Abstract:

Hybrid Energy Resource System (HERS) is studied and applied aroundworld in recent years. Control and monitor of them are quite important in realapplication. HERS also has the equirement to integral with power grid such asdistribution grid networks. Therefore, to design and implement the informationcommunication system following IEC 61850, which is most promising standard fordesign of substation communication and automation system, is necessary. This paperpresents the design of Information Communication Technology (ICT) architectureand Unified Modeling Language (UML) models and final implementation through LabVIEW programming for Smart Energy Container. Applying design following IEC61850 series standards allow the HERS can communicate and interoperate with other IEC61850 devices and SCADA systems. The implementation is applied to SmartEnergy Container which contains wind power, solar power, battery energy storagesystem, and hydrogen energy storage system. Verification and testing results shows thedesign is qualified to control and monitor Smart Energy Container. Smart Energy Container

Abstract:

In planning for future electricity supplies certain issues will need to be considered such as increased energy usage, urbanisation, reduction in personnel, global warming and the conservation of natural resources. As the result, some countries have investigated the transformation of their existing power grid to the so-called Smart Grid. The Smart Grid has three main characteristics which are, to some degree, antagonistic. These characteristics are the provision of good power quality, energy cost reduction and improvement in the reliability of the grid. The need to ensure that they can be accomplished together demands much richer Information and Communications Technology (ICT) networks than the current systems available. In this research we have identified the gap in the current proposals for the ICT of the power grid. We have designed and developed an ICT architecture for the neighbourhood sub-Grid level of the electrical network, where monitoring at this level is very underdeveloped because most current grids are controlled centrally and the response of the neighbourhood area is not generally monitored or actively controlled. Our designed ICT architecture, which is based on established architectural principles, can incorporate data from heterogeneous sources. This layered architecture provides both the sensors that can directly measure the electrical activity of the network (e.g. voltage) and also the sensors that measure the environment (e.g. temperature) since these provide information that can be used to anticipate demand and improve control actions. Additionally, we have de-signed a visualisation tool as an interface for a grid operators to facilitate a better comprehension of the behaviour of the neighbourhood level of the Smart Grid. Since we have noticed that energy aware ICT is a prerequisite for an efficient Smart Grid, we have utilised two different approaches to tackle this issue. The first approach was to utilise a cluster-based communication technique for the second layer of the architecture, which comprises Wireless Sensor Networks, where energy limitation is the major problem. Accordingly, we have analysed the energy-aware topology for wireless sensor networks embedded in the mentioned layer. We provide evidence that the proposed topology will bring energy efficiency to the communication network of the Smart Grid. The second approach was to develop a data reduction algorithm to reduce the volume of data prior to data transmission. We demonstrated that our developed data reduction is suitable for Smart Grid applications which can keep the integrity and quality of data. Finally, the work presented in this thesis is based on a real project that is being implemented in the medium voltage power network of the University of Manchester where power grid instrumentation, real data and professionals in the field are available. Since the project is long-term and the environmental sensor networks in particular are not currently installed we have evaluated some of our predictions via simulation. However, where the instrumentation was available, we were able to compare our predictions and our simulations with actual experimental results.

Abstract:

Thesis (Ph. D. in Design and Computation)--Massachusetts Institute of Technology, Dept. of Architecture, 2012. Cataloged from PDF version of thesis. Includes bibliographical references (p. 155-159 (i.e. [190]-[194])). Remote design comes with significant challenges. A major barrier to designing in remote regions is the lack of communication between designers and users. As a result, the lack of information flow leads to assumptions about the community's needs- an inherent weakness in the design process. This study examines the role that mobile phones play as a mode of communication between designers of products for communities in developing countries and the users within the communities themselves, in order to provide a better sense of context and environment. This study focused on the use of a communication software called mSurvey and its ability to create accessible feedback flows, that would otherwise be difficult to achieve within remote areas. The investigation uses three case studies as examples. These case studies differ in location, design team, and distance. The first case study took place in Trinidad and Tobago and had software engineers as the design team. The second case study, in Nairobi, Kenya, consisted of architects, engineers, and Masters of Business Administration (MBAs) as the design team. The third case study, in Tanzania, consisted of a company of over 160 employees, whose job titles ranged from designers and engineers, to supply chain strategists. The findings illustrate that, although each design task was different, there are similar challenges when designing for remote regions, specifically, developing countries. The solution to some of these challenges is the increased use of mobile technologies between designers and communities. by Kenfield Allistair Griffith. Ph.D.in Design and Computation

Abstract:

Not being able to, or not knowing how to make use of, ICT is becoming a clear factor of economic exclusion for businesses in developing countries. Several studies has investigated the correlation between access to information about ICT and the overall development of the country suggesting a strong bond. How information regarding ICT solutions can be structured to improve access has been investigated in this thesis using work conducted at the Havana University of Technologies José Antonio Echeverría in Cuba as a basis. This paper explores how information regarding the use of ICT in Cuban enterprises can be structured to eventually allow for further analysis. The information gathered is centered around Enterprise Architecture with a focus on alignment between business areas, processes and applications. The findings suggest that the information can be structured in a foreseeable manner using a database and the analysis of the data may be feasible. The report highlights the difficulties related to heterogeneity and dissimilarities of Enterprise Architecture data limiting the catalogue being used for statistical analysis. Furthermore, this paper gives a recommendation of how the gathering of the information regarding ICT solutions should be structured to increase the relevancy of the database and analysis. Att inte kunna eller inte veta hur man kan nyttja ICT är en betydande anledning förekonomisk uteslutning för företag i utvecklingsländer. Flera studier har undersökt korrelationen mellan tillgången till information om ICT, och den övergripande utvecklingen av landet som tyder på ett starkt band. Hur information kopplat till ICT lösningar kan struktureras för att ge nya insikter har undersökts i denna avhandling med hjälp av arbeten som utförts på Havana University of Technologies José Antonio Echeverría på Kuba som en fallstudie. I denna avhandling så undersöks hur samlad information om användningen av ICT i kubanska företag kan struktureras för att möjliggöra ytterligare analyser. Den information som samlas in är centrerad kring Enterprise Architecture med fokus på anpassning mellan affärsområden, processer och applikationer. Resultaten tyder på att informationen kan struktureras på ett överskådligt sätt med hjälp av en databas, och analysen av datan kan vara genomförbart. Avhandlingen belyser svårigheter kopplat till att heterogen Enterprise Architecture data och hur detta begränsar databasen från att tillämpa statistisk analys. Vidare ger denna avhandling en rekommendation om hur ytterligare insamling av informationen om ICT-lösningarna ska struktureras för att öka relevansen av databasen och analysen.

Abstract:

Kungliga Tekniska Högskolan har för en tid sedan anordnat så kallade ”workshops” för att hjälpa studenter med sina studier. Dessa workshops ger studenterna tillfälle att få hjälp av assistenter. Syftet med detta projekt är därför att göra administrationen för workshopstillfällena så effektiv och smidig som möjligt.För att uppnå detta syfte har en webbapplikation konstruerats i utvecklingsmiljön Netbeans och är baserad på en treskiktsarkitektur. Detta har genomförts med hjälp av utvecklingsmetoden Scrum och programmeringsspråket Java. Stor vikt har lagts på att skapa en modulär applikation med fokus på hållbar utveckling.Resultatet har blivit en webbapplikation som kan nås via mobila enheter, surfplattor och stationära enheter. Den har prestandatestats och är därmed redo för att testas för en utvärdering av dess effektivitet och inverkan på workshopverksamheten. The Royal Institute of Technology has recently arranged so-called "workshops" to help students with their studies. These workshops give students the opportunity to receive help from assistants. The purpose of this project is to make the administration of the workshop sessions as efficient and seamless as possible.To achieve this purpose, a web application has been designed in Netbeans the development environment and is based on three-layer architecture. This has been implemented using the Scrum development methodology and the Java programming language. Great emphasis was placed on creating a modular application with focus on sustainable development.The result is a web application that can be accessed via mobile devices, tablets, and stationary units. Its performance has been tested and the web application is thus ready to be tested in order to evaluate its effectiveness and impact on the workshop activities.

Abstract:

Travel demand forecasting is essential for many decisions, such as infrastructure investments and policy measures. Traditionally travel demand modelling has considered trip frequency, mode, destination and route choice. This thesis considers two other choice dimensions, hypothesised to have implications for travel demand forecasting. The first part investigates how the increased possibilities to overcome space that ICT (information and communication technology) provides, can be integrated in travel demand forecasting models. We find that possibilities of modelling substitution effects are limited, irrespective of data source and modelling approach. Telecommuting explains, however, a very small part of variation in work trip frequency. It is therefore not urgent to include effects from telecommuting in travel demand forecasting. The results indicate that telecommuting is a privilege for certain groups of employees, and we therefore expect that negative attitudes from management, job suitability and lack of equipment are important obstacles. We find also that company benefits can be obtained from telecommuting. No evidences that telecommuting gives rise to urban sprawl is, however, found. Hence, there is ground for promoting telecommuting from a societal, individual and company perspective. The second part develops a departure time choice model in a mixed logit framework. This model explains how travellers trade-off travel time, travel time variability, monetary and scheduling costs, when choosing departure time. We explicitly account for correlation in unobserved heterogeneity over repeated SP choices, which was fundamental for accurate estimation of the substitution pattern. Temporal constraints at destination are found to mainly restrict late arrival. Constraints at origin mainly restrict early departure. Sensitivity to travel time uncertainty depends on trip type and intended arrival time. Given appropriate input data and a calibrated dynamic assignment model, the model can be applied to forecast peak-spreading effects in congested networks. Combined stated preference (SP) and revealed preference (RP) data is used, which has provided an opportunity to compare observed and stated behaviour. Such analysis has previously not been carried out and indicates that there are systematic differences in RP and SP data. QC 20100825

Abstract:

The last two decades have seen rapid evolution of Information and Communication Technology (ICT) capabilities in the public sector which facilitate the adoption of several IT innovations. E-government is one of these strategic innovations that many government organisations have considered adopting to deliver government information and services to citizens and to support the modernisation of their business processes. This work therefore investigates this issue through a study of the impact of e-government on government organisations and their capabilities towards the e-government adoption. This has led to developing a framework for e-government adoption that outlines the implementation process, determines critical factors influencing adoption, and identifies barriers that could keep government organisations behind the advanced stages of the implementation process. The research also proposes a novel architecture framework for e-government that offers a clear picture of ICT requirements, along with a business process model needed for the implementation for e-government. This framework also supports the researcher in terms of validating the proposed conceptual framework in case organisations. The researcher, by adopting a qualitative case study strategy, examines the proposed framework in three government organisations in the Kingdom of Bahrain.. The analysis of empirical data comes up with a novel comprehensive framework for e-government adoption in the public sector that can be a benefit in multiple ways. The major benefit of this framework is to reduce the confusion surrounding e-government adoption in the public sector by understanding the implementation process, identifying the requirements of ICT tools, and highlighting the importance of organisational readiness and the impact of the environment. The framework can also help decision makers in government to provide a clear strategic action plan for e-government. Finally, the proposed framework can be used by IT experts to estimate the progress level of their e-government projects.

Abstract:

De nos jours la plupart des organisations pour ne pas dire toutes, dépendent des technologies de l'information et de la communication (TIC) pour supporter plusieurs tâches et processus (quelquefois critiques). Cependant, dans la plupart des cas, les organisations et en particulier les petites entreprises accordent une importance limitée à l'information et à sa sécurité. En outre, sécuriser de tels systèmes est une tâche difficile en raison de la complexité et de la connectivité croissante du matériel et du logiciel dans le développement des TICs. Cet aspect doit alors être pris en compte dès les premières phases de conception. Dans ce travail, nous proposons une approche basée sur les modèles permettant de sécuriser des architectures logicielles en utilisant des patrons. Les contributions de ce travail sont : (1) un cadre de conception intégré pour la spécification et l'analyse d'architectures logicielles sécurisées, (2) une nouvelle méthodologie à base de modèles et de patrons et (3) une suite d'outils. Le fondement de l'approche associe un environnement basé sur des langages de modélisation pour la spécification et l'analyse des modèles d'architectures sécurisées et un dépôt à base de modèles d'artéfacts dédiés à la sécurité (modèle de patrons de sécurité, menaces et propriétés de sécurités) permettant la réutilisation de savoir-faire et de connaissances capitalisées. Pour cela on utilise des langages de modélisation pour la spécification et l'analyse de l'architecture. Le processus associé est constitué des activités suivantes : (a) analyse de risques à base de modèle appliquée à l'architecture du système pour identifier des menaces, (b) sélection et importation de modèles de patrons de sécurité, afin d'arrêter ou de mitiger les menaces identifiées, vers l'environnement de modélisation cible, (c) intégration de modèles de patrons dans le modèle d'architecture, (d) analyse de l'architecture obtenue par rapports aux exigences non-fonctionnelles et aux menaces résiduelles. Dans ce cadre, on s'est focalisé sur la vérification du maintien du respect des contraintes temporelles après application des patrons. La recherche de menaces résiduelles est réalisée à l'aide de techniques de vérification exploitant une représentation formelle des scénarios de menaces issus du modèle STRIDE et basés sur des référentiels de menaces existants (ex., CAPEC). Dans le cadre de l'assistance pour le développement des architectures sécurisées, nous avons implémenté une suite structurée d'outils autour du framework SEMCO et de la plateforme Eclipse Papyrus pour supporter les différentes activités basées sur un ensemble de langages de modélisation conforme à des standards OMG (UML et ses profils). Les solutions proposées ont été évaluées à travers l'utilisation d'un cas d'étude autour des systèmes SCADA (systèmes de contrôle et d'acquisition de données) Nowadays most organizations depend on Information and Communication Technologies (ICT) to perform their daily tasks (sometimes highly critical). However, in most cases, organizations and particularly small ones place limited value on information and its security. In the same time, achieving security in such systems is a difficult task because of the increasing complexity and connectivity in ICT development. In addition, security has impacts on many attributes such as openness, safety and usability. Thus, security becomes a very important aspect that should be considered in early phases of development. In this work, we propose an approach in order to secure ICT software architectures during their development by considering the aforementioned issues. The contributions of this work are threefold: (1) an integrated design framework for the specification and analysis of secure software architectures, (2) a novel model- and pattern-based methodology and (3) a set of supporting tools. The approach associates a modeling environment based on a set of modeling languages for specifying and analyzing architecture models and a reuse model repository of modeling artifacts (security pattern, threat and security property models) which allows reuse of capitalized security related know-how. The approach consists of the following steps: (a) model-based risk assessment performed on the architecture to identify threats, (b) selection and instantiation of security pattern models towards the modeling environment for stopping or mitigating the identified threats, (c) integration of security pattern models into the architecture model, (d) analysis of the produced architecture model with regards to other non-functional requirements and residual threats. In this context, we focus on real-time constraints satisfaction preservation after application of security patterns. Enumerating the residual threats is done by checking techniques over the architecture against formalized threat scenarios from the STRIDE model and based on existing threat references (e.g., CAPEC). As part of the assistance for the development of secure architectures, we have implemented a tool chain based on SEMCO and Eclipse Papyrus to support the different activities based on a set of modeling languages compliant with OMG standards (UML and its profiles). The assessment of our work is presented via a SCADA system (Supervisory Control And Data Acquisition) case study

It therefore consists of not only theoretical research but also of applied work. First goal of this paper was to provide information base both about (especially electronic) voting and significant electronic voting projects realized throughout the world. Consequent second goal was analysis and design of electronic voting solution for chosen elections type at the University of Economics, Prague and proposal of possible process changes in chosen type of elections in the Czech republic should electronic voting be implemented. In it's first part the paper gathers, summarizes and presents information about (especially electronic) voting and chosen electronic voting implementations. The second part then describes chosen types of elections at the University of Economics, Prague and in the Czech Republic and analyzes their processes. In former case the analysis is followed by proposition and evaluation of possible electronic voting implementation variants of chosen elections type and detailed elaboration of the most suitable one. In latter case the paper goes on to describe possible process changes that could arise should electronic voting be implemented for chosen elections type in the Czech Republic. Author's contribution lies in fulfilling the goals of this thesis and performing the necessary activities leading to them. Following the (electronic) voting research the author has provides the reader with information base needed to quickly orientate tehmselves in the field of electronic voting. The author then leverages this information to research and process-analyze chosen types of elections at the University of Economics, Prague and in the Czech Republic, propose changes in mapped processes needed for eventual electronic voting implementation, present alternatives of electronic voting implementation of chosen elections type at the University of Economics, Prague and elaborate on the chosen most suitable one.

Abstract:

Les céramiques macroporeuses sont largement utilisées dans des applications telles que la filtration, l'isolation thermique, les scaffolds pour la croissance de tissus biologiques, les SOFC, ou encore les OTM. En plus d’une bonne stabilité mécanique, ces céramiques doivent généralement posséder une autre propriété fonctionnelle, comme une perméabilité élevée, une faible conductivité thermique, ou une biocompatibilité. Cependant, la résistance mécanique est généralement augmentée en diminuant le volume total des pores, même si cela peut dégrader d’autres propriétés fonctionnelles. Au-delà de la porosité, des paramètres morphologiques tels que la taille des pores, leur forme ou la tortuosité, peuvent devenir cruciaux pour maximiser les performances, tout en conservant une grande résistance mécanique. Une importante amélioration des propriétés mécaniques peut par exemple être obtenue par des structures anisotropes. Celles-ci renforcent les structures dans la direction de la contrainte principale, de manière similaire aux matériaux naturels tels que l'os trabéculaire, le liège ou le bois. Néanmoins, la plupart des techniques classiquement utilisées pour produire des céramiques macroporeuses ne proposent pas ce niveau de flexibilité. L’ ice-templating est une technique de mise en forme appropriée pour obtenir des matériaux macroporeux anisotropes. Elle est basée sur la congélation de suspensions colloïdales et la séparation ultérieure des particules par le front de solidification. Le solvant congelé est ensuite éliminé, en laissant des pores dont les morphologies sont une réplique des cristaux sublimés. Enfin, le matériau cru est fritté pour consolider la microstructure. Ce processus assure un contrôle indépendant de l'architecture des pores (volume des pores, la taille et la morphologie) à travers la fraction de solides initiale, la vitesse de refroidissement, ou les éventuels additifs. Par conséquent, une bonne compréhension de ces paramètres est essentielle afin d’établir un lien entre les procédés de mise en forme, la microstructure, et les performances de ce type de matériaux et d'étendre leur utilisation dans les applications mentionnées précédemment. L’objectif de ce travail est premièrement, d’adapter l'architecture des pores faits par l’ice-templating pour ensuite, déterminer les principaux paramètres des microstructures qui contrôlent la résistance à la compression, la fiabilité mécanique, et la perméabilité de ces matériaux poreux unidirectionnels. En outre, l'applicabilité des modèles de flux mécanistique et de flux de gaz sera discutée dans le contexte des morphologies de pores structurés. Enfin, nous allons fournir des lignes directrices pour produire des échantillons tubulaires produits par ice-templating Macroporous ceramics are widely used in applications such as filtration, thermal insulation, scaffolds for tissue engineering, SOFCs, or OTM’s. They must combine mechanical stability with at least one other functional property such as high permeability, low thermal conductivity, or biocompatibility. However, strength is usually increased by decreasing the total pore volume even though this may degrade the other functional properties. Beyond porosity content, morphological parameters such as pore size, shape, or tortuosity, can become crucial to maximize the performance while maintaining high strength. For example, a significant improvement can be achieved by engineering anisotropic structures to mechanically reinforce the direction of the main stress, similarly to natural materials such as trabecular bone, cork, or wood. Unfortunately, most of the techniques conventionally used to produce macroporous ceramics do not offer this level of flexibility. Ice-templating is a processing technique suitable to obtain anisotropic macroporous materials. It is based on the freezing of colloidal suspensions and the subsequent segregation of particles by the solidification front. After solidification, the frozen solvent is removed, leaving pores whose morphologies are a replica of the sublimated crystals. Finally, the green body is sintered to consolidate the microstructure. This process provides independent control of the pore architecture (pore volume, size, and morphology) through initial solids loading, cooling rate, or additives. Therefore, a good understanding of these parameters is essential to understand the relationship between processing, microstructure, and performance of this type of materials and extend their use in the aforementioned applications.The purpose of this work is first, tailor the pore architecture of specimens processed by ice-templating to then, determine the main microstructural parameters that control the compressive strength, mechanical reliability, and air permeability of unidirectional porous materials. Furthermore, the applicability of mechanistic and gas flow models will be discussed in the context of the structured pore morphologies. Finally, we will provide some guidelines to produce tubular ice-templated samples with controlled porosity.The purpose of this work is first, tailor the pore architecture of specimens processed by ice-templating to then, determine the main microstructural parameters that control the compressive strength, mechanical reliability, and air permeability of unidirectional porous materials.

Abstract:

La esencia del trabajo consta de estudios y análisis de la cultura y la educación propia de la ciudad de Ica, para un desarrollo integral que fortalezca aquello que se va perdiendo, usando métodos que vinculen a la sociedad y su identidad. Al investigar más acerca de las necesidades y problemáticas de la ciudad, sale a flote la gran demanda de visitantes nacionales, residentes y extranjeros a sectores cuyas características están ligadas a la falta de infraestructura cultural. Seguidamente el número excesivo de estudiantes en instituciones pedagógicas en relación a la cantidad de colegios, universidades, institutos, etc. Esta información se va ver reflejado en la propuesta multianual de inversiones del Ministerio de Cultura, que propone el desarrollo de un Centro cultural en Ica, vinculado a solucionar las 2 problemáticas con mayor demanda. Por este motivo se propone dicha tipología que aborde un programa consecuente a la falta de ambientes que tienen las instituciones cercanas al proyecto, al igual que la factibilidad para vincular una ruta cultural, que ofrece salas de exposición pertenecientes a restos arqueológicos de Paracas, donde actualmente se exponen en edificaciones no adecuadas para su conservación. Bajo estas circunstancias es como se desarrollará el proyecto cumpliendo un rol que vincule los lazos de la identidad Iqueña, como también ser pionero al marcar pautas acerca del correcto emplazamiento, sistemas de asoleamiento, materialidad a través del mimesis con el entorno, etc. Siendo un punto de partida para hacer arquitectura pensada para el lugar. The essence of the work consists of studies and analysis of the culture and education of the city of Ica, for an integral development that strengthens what is being lost, using methods that link society and its identity. When investigating more about the needs and problems of the city, the great demand of national visitors, residents and foreigners to sectors whose characteristics are linked to the lack of cultural infrastructure comes to the fore. Then the excessive number of students in educational institutions in relation to the number of colleges, universities, institutes, etc. This information will be reflected in the multi-annual investment proposal of the Ministry of Culture, which proposes the development of a Cultural Center in Ica, linked to solving the 2 problems with greater demand. For this reason, this typology is proposed that addresses a program consistent with the lack of environments that the institutions near the project have, as well as the feasibility to link a cultural route, which offers exhibition halls belonging to archaeological remains of Paracas, where currently They are exhibited in buildings not suitable for conservation. Under these circumstances it is how the project will be developed, fulfilling a role that links the ties of the Iqueña identity, as well as being a pioneer in setting guidelines on the correct location, sunning systems, materiality through mimesis with the environment, etc. Being a starting point to make architecture designed for the place.

Abstract:

Le paradigme de MEC (Mobile Edge Computing) consiste à mettre les ressources de calcul et de stockage aux « extrémités » du réseau à proximité des utilisateurs finaux. Le terme « edge » désigne n’importe quel type de station de base de réseau. Les motivations pour l’adoption de ce nouveau concept sont principalement la réduction de la charge au cœur du réseau et la diminution de la latence grâce à la proximité des ressources et ainsi améliorer l’expérience utilisateur. Les serveurs MEC sont de bons candidats pour héberger les applications mobiles et diffuser le contenu Web. La mise en cache à l’extrémité du réseau, ou Edge Caching en anglais, est l’une des technologies les plus émergentes connues comme solution de récupération de contenu au bord du réseau. Elle est aussi considérée comme une technologie permettant la mise en place du concept MEC puisqu’elle présente une opportunité intéressante pour implémenter les services de mise en cache. En particulier, les serveurs MEC sont implémentés directement au niveau des stations de base, ce qui permet la mise en cache à l’extrémité du réseau et assure un déploiement à proximité des utilisateurs finaux. Cependant, l’intégration des serveurs MEC dans les stations de base complexifie le problème de la consommation de l’énergie, particulièrement dans un tel environnement qui est dynamique et sujet à des changements au fil du temps. Par ailleurs, la demande des utilisateurs des appareils mobiles est en constante augmentation ainsi que leur expectation d’une expérience meilleure. Sachant que le cache est d’une taille limitée, il est donc nécessaire et crucial que les mécanismes de mise en cache soient en mesure de faire face à cette situation et de proposer des solutions valables et satisfaisants à long terme. La plupart des études existantes se sont focalisées sur l’allocation de cache, la popularité du contenu ou encore la manière de concevoir le cache. Dans cette thèse, nous présentons une nouvelle stratégie de mise en cache écoénergétique basée sur la logique floue (Fuzzy logic). Notre proposition prend en compte les quatre caractéristiques d’un environnement mobile et introduit une implémentation matérielle en utilisant les FPGA (Field-Programmable Gate Array) pour réduire les besoins globaux en énergie. L’adoption d’une stratégie de mise en cache adéquate sur les serveurs MEC ouvre la possibilité d’utiliser des techniques d’intelligence artificielle (IA) et d’apprentissage automatique (Machine Learning) aux extrémités des réseaux mobiles. L’exploitation des informations de contexte des utilisateurs permet de concevoir une mise en cache intelligente sensible au contexte. La reconnaissance du contexte permet au cache de connaître son environnement, tandis que l’intelligence lui permet de prendre les bonnes décisions en sélectionnant le contenu approprié à mettre en cache afin d’optimiser les performances du caching. Inspiré par le succès de l’apprentissage par renforcement utilisant des agents pour traiter des problèmes de prise de décision, nous avons étendu notre système de mise en cache basé sur la logique floue à un modèle d’apprentissage par renforcement modifié. Le cadre proposé vise à maximiser le taux de réussite du cache (hit rate) et nécessite une prise de conscience multiple sure les conditions de web et l’utilisateur final. La méthode d’apprentissage par renforcement modifiée diffère des autres algorithmes par le taux d’apprentissage qui utilise la méthode du gradient stochastique décent (stochastic gradient decent) en plus de tirer parti de l’apprentissage en utilisant la décision de mise en cache optimale obtenue à partir des règles de la logique floue Mobile edge computing (MEC) concept proposes to bring the computing and storage resources in close proximity to the end user by placing these resources at the network edge. The motivation is to alleviate the mobile core and to reduce latency for mobile users due to their close proximity to the edge. MEC servers are candidates to host mobile applications and serve web contents. Edge caching is one of the most emerging technologies recognized as a content retrieval solution in the edge of the network. It has been also considered as enabling technology of mobile edge computing that presents an interesting opportunity to perform caching services. Particularly, the MEC servers are implemented directly at the base stations which enable edge caching and ensure deployment in close-proximity to the mobile users. However, the integration of servers in mobile edge computing environment (base stations) complicates the energy saving issue because the power consumed by mobile edge computing servers is costly especially when the load changes dynamically over time. Furthermore, users with mobile devices arise their demands, introducing the challenge of handling such mobile content requests beside the limited caching size. Thus, it is necessary and crucial for caching mechanisms to consider context-aware factors, meanwhile most existing studies focus on cache allocation, content popularity and cache design. In this thesis, we present a novel energy-efficient fuzzy caching strategy for edge devices that takes into consideration four influencing features of mobile environment, while introducing a hardware implementation using Field-Programmable Gate Array (FPGA) to cut the overall energy requirements. Performing an adequate caching strategy on MEC servers opens the possibility of employing artificial intelligence (AI) techniques and machine learning at mobile network edges. Exploiting users context information intelligently makes it possible to design an intelligent context-aware mobile edge caching. Context awareness enables the cache to be aware of its environment, while intelligence enables each cache to make the right decisions of selecting appropriate contents to be cached so that to maximize the caching performance. Inspired by the success of reinforcement learning (RL) that uses agents to deal with decision making problems, we extended our fuzzy-caching system into a modified reinforcement learning model. The proposed framework aims to maximize the cache hit rate and requires a multi awareness. The modified RL differs from other RL algorithms in the learning rate that uses the method of stochastic gradient decent beside taking advantage of learning using the optimal caching decision obtained from fuzzy rules

Abstract:

Este documento surge por la aparición de una vivienda social inadecuada en Ica, por no responder al estilo de vida del usuario y por no entender su desarrollo económico en el tiempo. El estado a través de la empresa privada busca solucionar la demanda existente de vivienda presentando una estandarización de módulos de vivienda para agilizar su construcción, y llegar a las metas establecidas. Se entregan módulos básicos construidos con la opción de expandirlos a través del tiempo, sin embargo, los módulos entregados no suelen entender el contexto inmediato donde se emplazan y tampoco comprenden el estilo de vida de las familias causando una inversión adicional a pesar de poder expandirlos en el tiempo, porque los residentes al expandirlos, tratan de moldear estos módulos con su identidad probando soluciones informales y a veces arriesgadas, demostrando el desinterés del estado y la empresa privada por la realidad del usuario y su desarrollo económico. Esta investigación se hizo para demostrar la importancia de entender al ser humano, para comprender su realidad, y para precisar que el arquitecto tiene un rol social importante en mejorar la vida de las personas. This document arises from the appearance of inadequate social housing in Ica, for not responding to the user's lifestyle and for not understanding their economic development over time. The state, through private companies, seeks to solve the existing demand for housing by presenting a standardization of housing modules to speed up their construction and reach the established goals. Basic modules built with the option of expanding them over time are delivered, however, the modules delivered do not usually understand the immediate context where they are located nor do they understand the lifestyle of families causing an additional investment despite being able to expand them in over time, because residents, by expanding them, try to mold these modules with their identity, testing informal and sometimes risky solutions, demonstrating the disinterest of the state and private companies for the reality of the user and their economic development. This research was done to demonstrate the importance of understanding the human being, to understand his reality, and to specify that the architect has an important social role in improving people's lives.

Abstract:

Background. PAC controller is a strengthened version of PLC controller. Its function is very similar, but its essence and construction are different. PLC and PAC have many successful applications in the field of industrial automation control. There is a lot of literature about the software architecture of PLC control system. However, there is almost no relevant literature on software architecture based on PAC control system. A well-performing and stable automatic control system is indispensable to the design and development of suitable software architecture. The quality and pattern of software architecture can even affect the stability and efficiency of the control system. Objectives. Based on these problems, we defined two primary objectives. The first is to investigate the architecture of some existing large industrial control systems, to analyze and summarize the scenarios and advantages and disadvantages of these architectural patterns. The second, based on the results of effort for the first objective, we want to propose and design a set of automated control solution architecture model based on PAC control system, which is implemented and applied in a printing house. In the process, we sum up the challenges and obstacles encountered in implementing the solution and provide some guidance or reference for those involved in the field. Methods. For the first objective, we used a systematic literature review to collect data about existing ICS architecture. Concerning the second objective, a case study was conducted in a printing house in Karlskrona Sweden, in the study, we proposed a software architecture model suitable for PAC automation control system. Then, we developed and tested the automation control system and summarized some challenges and obstacles in the process of the implementation. Results. The existing ICS (Industrial Control System) architecture models and critical problems and challenges in the implementation of ICS are identified. From the existing literature, we have summarized five commonly used large industrial control system architecture models, which are mainly using composite structures, that is, a combination of multiple architecture patterns. Also, some critical problems in the industrial control system, such as information security, production reliability, etc. are also identified. In the case study, we put forward an automatic control solution for Printing House based on SLR results. We designed the hardware deployment architecture of the system and the software control architecture. Generally speaking, this architecture is based on C/S architecture. In the development of client, we adopt the popular MVC architecture mode. In the longitudinal view of the whole system, an extended hierarchical architecture model is adopted. In the core control system, we adopt the modular architecture design idea. The whole control system is composed of 6 parts, four subsystems of PAC terminal, one server-side program and one client program. After a long time, development and test, our system finally goes online for the production, and its production efficiency is improved compared with the old system. Its expansion functions, such as Production Report and Tag Print, are deeply satisfying for the customers. Conclusions. In this research, we summarize and compare the advantages and disadvantages of several commonly used industrial control systems. Besides, we proposed a software architecture model and developed an automation control system based on PAC. We fill the gap that there is a lack of studies about the software architecture about the implementation of the automation control system based on PAC. Our result can help software engineers and developers in ICS fields to develop their own PAC based automation control system.

Abstract:

Industrial Control Systems are essential to modern life. They are utilized in hundreds of processes including power distribution, water treatment, manufacturing, traffic management, and amusement park ride control. These systems are an essential part of modern life and if compromised, could result in significant economic loss, safety impacts, damage to the environment, and even loss of life. Unfortunately, many of these systems are not properly secured from a cyber attack. It is likely that a well-funded and motivated attack from a nation-state will successfully compromise an industrial control system's network. As cyber war becomes more prevalent, it is becoming more critical to find new and innovative ways to reduce the physical impacts from a cyber attack.This thesis presents a new architecture for a secure industrial controller. This architecture protects the integrity of the controller logic, including the safety logic which is responsible for keeping the process in a safe condition. In particular, it would prevent malicious or accidental modification or bypassing of the controller logic. This architecture divides the controller into three components; the logic controller, the interface controller and the SAP link. The logic controller is responsible for controlling the equipment and contains the safety logic. The interface controller communicates with the rest of the control system network. The Simple As Possible (SAP) link is a bridge between the logic and interface controllers that ensures the integrity of the logic controller by drastically limiting the external interface of the logic controller. We implement this new architecture on a physical controller to demonstrate the process of implementing the architecture and to demonstrate its feasibility.

Abstract:

Avec la prolifération des appareils mobiles, la mobilité devient une exigence et une caractéristique incontournable pour 5G. Cependant, en dépit des efforts pour permettre la mobilité dans le réseau IP, les solutions sont anchor-basées et inefficaces. Dans ce contexte, le réseau centré sur l'information (ICN) est proposé. Alors que ICN soutient mieux la mobilité, certains défis restent sans solution pour une mobilité transparente. La thèse explore trois défis de ce type et propose solutions efficaces. Tout d'abord, pour résoudre la mobilité des producteurs, MapMe, un protocole de gestion de micro mobilité compatible avec trafics latence-sensibles est proposée. MAP-Me est sans anchor et préserve les avantages de l'ICN. Les résultats de simulation montrent que MAP-Me surpasse les autres solutions en matière de performances client tout en gardant bas les frais de réseau sur diverses conditions réseau. En plus, nous étudions la sécurité de mobilité des producteurs. Nous nous concentrons sur l'attaque de préfixe hijacking, qui est à la base de plusieurs attaques. Pour éviter cette attaque, nous proposons un protocole léger et distribué basé sur hash-chaining. Les premiers résultats montrent une amélioration significative des frais de vérification. Enfin, il faut d'autres mécanismes dans la couche transport pour ICN mobile. Nous proposons WLDR et MLDR pour la détection et la récupération des pertes dans le réseau afin de faciliter le contrôle de la congestion. Les résultats de simulation montrent une réduction significative du temps d'écoulement (jusqu'à 20%) With the proliferation of mobile devices, mobility becomes a requirement and a compelling feature for 5G. However, despite tremendous efforts in the last 2 decades to enable mobility in IP network, the solutions are mostly anchor-based and inefficient. In this context, Information-Centric networking (ICN) is proposed. While ICN has some native support of mobility, other architectural challenges remain unsolved to achieve seamless mobility. The thesis explores 3 main challenges of such and contributes novel solutions. First, to solve producer mobility, MapMe, a micro mobility management protocol supporting latency sensitive traffic is proposed. MAP-Me is anchorless and preserves key ICN benefits. Simulation results show that MAP-Me outperforms existing work in user performance while retaining low network overheads in various network conditions. Second, we investigate security in producer mobility. We focus on prefix hijacking attack, which is a basis of several attacks. To prevent prefix hijacking, we propose a light-weight and distributed prefix attestation protocol based on hash-chaining. First results show significant improvement in verification overhead. It is resistant to replay-based prefix hijacking. Finally, additional transport-layer mechanisms are needed in mobile ICN. To this aim, we investigate alleviating the adverse effect of wireless/mobility loss on congestion control. We propose WLDR and MLDR for in-network loss detection and recovery to facilitate congestion control. Simulation results show a significant reduction in flow completion time (up to 20%)

Abstract:

Honeypots are progressively becoming a fundamental cybersecurity tool to detect, prevent, and record new threats and attack methodologies used by attackers to penetrate systems. A honeypot is a deceptive or fake computer system that presents itself as a real computer system with actual sensitive information. A range of open-source honeypots are available today, such as Cowrie and Conpot, which can be easily downloaded and deployed within minutes—with default settings. Cowrie is a medium-interaction secure shell (SSH) and Telnet honeypot intended to log brute force and shell interaction attacks. In contrast, Conpot is a low-interaction SCADA honeypot, which attempts to mimic an active SCADA system. These honeypots operate on a standardised configuration file that encompass options for deployment such as hostnames, IPs, network services, protocols, applications, and fingerprint information. These options are convoluted and must be used in an integrated and granular fashion to make the deception presented by the honeypot to be plausible and effective. The current issue with the default configurations is that it is easily detected by adversaries using default parameters, automated scripts and scanners such as Shodan and NMAP. Nonetheless, cybersecurity specialists deploy most honeypots with default configurations. This is because modern systems do not provide a standard framework for optimal deployment of these honeypots based on the various configuration options available to produce a non-default configuration. Hence, default honeypot deployments are counterproductive and a surplus network resources and personnel. A quantitative empirical learning approach driven by a quasi-experimental methodology was undertaken to develop a solid understanding about the deceptive capabilities of the Cowrie and Conpot honeypots. This was accomplished by developing a framework created from the analysis of numerous Cowrie and Conpot configurations and linking these artefacts to their deceptive potential. This framework provides for customised honeypot configuration, thereby enhancing their functionality to achieve a high degree of deceptiveness and realism. Thereafter, these configured honeypots were then deployed in association with banners and firewall rules to prevent Shodan and NMAP detections and to prevent attackers from acknowledging default parameters. The results of these deployments show an exponential increase in attackerhoneypot interaction in comparison to their subsequent default implementations. In turn, they inform and educate cybersecurity audiences how important it is to deploy honeypots with advanced deceptive configurations to bait cybercriminals and mitigate counterproductive distributions.

Abstract:

This paper presents and discusses the results of recent investigations carried out by the Ánimas Altas Archaeological Program, in the Ica department, southern Peru. A particular emphasis is put on the excavations conducted at a frieze-decorated building. The analysis of the material culture registered in this building, particularly of the icons depicted on the friezes, not only offers some interpretations regarding Paracas symbology and cosmovision but also sheds lights on critical aspects related to identity as well as the territorial dynamics of the Paracas social formations from the lower section of the Ica valley. Furthermore, imagery depicted on friezes support the idea that social interactions promoted by the Paracas were not limited to the adjacent highland. Even more, potential links with the north and central coast from remote timesneed to be further investigated. The stylistic and technological variations registered at the «Building of Friezes» – which are not diachronically manifested, can reveal diverse phenomena such as the occupation of the territory by several groups that gave shape to socio-political identities in Late Paracas times. The comparison between the data obtained from the excavation at the «Building of Frizes» and other Paracas sites´will allow Paracas scholars to formulate interpretations and hypotheses about both the political and cultural spaces of the ancient Paracas. En este artículo, se presentan y se discuten los resultados de las recientes investigaciones llevadas a cabo en el marco del Programa Arqueológico Ánimas Altas, Ica, Perú. Se enfatizan las excavaciones realizadas en un edificio decorado con frisos. El análisis de la cultura material de este edificio —en particular, de los íconos plasmados en los frisos— ofrece algunas interpretaciones no solamente respecto a la simbología y cosmovisión paracas; también, arroja luces sobre aspectos relacionados con dinámicas identitarias y territoriales de las formaciones sociales paracas en el valle bajo de Ica. Los íconos plasmados en los frisos apoyan la idea según la cual las interacciones de los paracas no se limitaron a la sierra adyacente. Más aún, existen nexos con la costa norte y central desde épocas remotas que quedan por investigar. Las variacionesestilísticas y tecnológicas observadas en el Edificio de los Frisos —que no se manifiestan en diacronía— pueden revelar varios fenómenos, entre ellos, la ocupación del territorio por varios grupos que formaron entidades sociopolíticas en la época Paracas Tardío. Las comparaciones entre los datos proporcionados por las excavaciones del Edificio de los Frisos con los de otros sitios permitirán formular interpretaciones e hipótesis sobre el espacio político y cultural de los paracas.

Abstract:

L’Internet des objets (IdO) utilise l’interconnexion de milliards de petits appareils informatiques, appelés «Objets», pour fournir un accès à des services et à des informations partout dans le monde. Cependant, la suite de protocoles IP a été conçue il y a plusieurs décennies dans un but totalement différent, et les fonctionnalités de l’IoT soulignent désormais les limites de l’IP. En parallèle aux efforts d’adaptation de l’IP à l’IdO, des architectures alternatives basées sur les réseaux orientés information promettent de satisfaire nativement les applications Internet émergentes. L’une de ces architectures est appelée réseau de données nommées (NDN). Nos objectifs à travers le travail rapporté dans ce manuscrit peuvent êtrerésumés en deux aspects. Le premier objectif est de montrer que NDN est adapté à la prise en charge des systèmes IdO. Le deuxième objectif est la conception de deux solutions de communication légères pour les réseaux sans fil contraints avec NDN The Internet of Things (IoT) uses the interconnection of billions of small computing devices, called “Things”, to provide access to services and information all over the world. However, the IP protocol suite has been designed decades ago for a completely different purpose, and IoT features now highlight the limitations of IP. While adapting IP for the IoT might be seen as cutting corners, alternative architectures based on the Information Centric Networking (ICN) paradigm promise to natively satisfy emerging Internet applications. One of these architectures is Named Data Networking (NDN). Our objectives through the work reported in this manuscript can be summarized in two aspects. The first objective is to show that NDN is suitable to support IoT networking. The second objective is the design of two solutions for lightweight forwarding in constrained wireless networks

Abstract:

L'objectif de ces travaux de recherche est l'étude et le développement d'un système ICM embarqué en utilisant la méthodologie de conception conjointe afin de satisfaire ses contraintes spécifiques. Il en a découlé la constitution d'un système ICM complet intégrant un système d'acquisition OpenBCI et un système de traitement à base de FPGA. Ce système pourrait être utilisé dans des contextes variés : médicale (pour les diagnostiques précoces des pathologies), technologique (informatique ubiquitaire), industriel (communication avec des robots), ludique (contrôler un joystick dans les jeux vidéo), etc. Dans notre contexte d’étude, la plateforme ICM proposée a été réalisée pour assister les personnes à mobilité réduite à commander les équipements domestiques. Nous nous sommes intéressés en particulier à l'étude et à l'implémentation des modules de filtrage adaptatif et dynamique, sous forme d'un coprocesseur codé en HDL afin de réduire son temps d'exécution car c'est le bloc le plus critique de la chaine ICM. Quant aux algorithmes d'extraction des caractéristiques et de classification, ils sont exécutés par le processeur Nios-II sous son système d'exploitation en ANSI-C. Le temps de traitement d'un trial par notre système ICM réalisé est de l'ordre de 0.4 s/trial et sa consommation ne dépasse guère 0.7 W The main purpose of this thesis is to study and develop an embedded brain computer interface (BCI) system using HW/SW methodology in order to satisfy the system specifications. A complete BCI system integrated in an acquisition system (OpenBCI) and a hardware platform based on the FPGA were achieved. The proposed system can be used in a variety of contexts: medical (for early diagnosis of pathologies, assisting people with severe disabilities to control home devices system through thought), technological (ubiquitous computing), industrial (communication with Robots), games (control a joystick in video games), etc. In our study, the proposed ICM platform was designed to control home devices through the thought of people with severe disabilities. A particular attention has been given to the study and implementation of the filtering module, adaptive and dynamic filtering, in the form of a coprocessor coded in HDL in order to reduce its execution time as it is the critical block in the returned ICM algorithms. For the feature extraction and classification algorithms, they are executed in the Nios-II processor using ANSI-C language. The prototype operates at 200 MHz and performs a real time classification with an execution delay of 0.4 second per trial. The power consumption of the proposed system is about 0.7 W

Abstract:

Hårdare energidirektiv från EU gällande energianvändning i byggnader har resulterat i Boverkets framtagande av Sveriges kommande nära-nollenergilagstiftning. Den kommande lagstiftningen kommer ur energisynpunkt innebära ett paradigmskifte för hur man projekterar och bygger nya byggnader i Sverige. I samarbete med WSP Sverige AB har detta arbete huvudsakligen undersökt potentialen att klara av denna omställning, genom att fokusera på minimering av energiförluster från transmission i en byggnads klimatskal. Arbetet innehåller en omprojektering av en specifik byggnads klimatskal. Vid framtagandet av detta klimatskal har olika konstruktionsalternativ simulerats och analyserats för att på ett kostnadseffektivt sätt avgöra den ambitionsnivå som krävs för att uppnå kraven i den kommande lagstiftningen. Utöver Boverkets kommande lagstiftning har även möjligheten att klara av viktade krav från miljöclassifieringssystemet Miljöbyggnad analyserats.

Abstract:

As a result of the quick rise of pXRF technology in archaeology, there are concerns regarding the reliability and validity of data output acquired from pXRF. In this study, I test the hypothesis that portable X-ray fluorescence (pXRF) spectrometry can provide reliable and valid results, using newly developed calibration curves, for the analysis of archaeological animal and human skeletal materials in prehistoric Peru to address hypotheses about ancient diet and trade. While pXRF systems may come with calibration software, the few if any standards and reference materials provided with the instrument rarely correspond to the vast array of archaeological materials capable of being analyzed by pXRF, including archaeological bone specimens. Empirical calibration curves for Ba, Ca, Fe, and Sr were created using the linear regression analysis of 19 human and animal bone standards analyzed via pXRF and ICP-MS. The results suggest the calibrations for Ca and Sr are sound, but the calibrations for Ba and Fe need to be further improved. In order to assess the reliability of pXRF (i.e. precision and accuracy), statistical analyses of 60 measurements on human bone specimens as well as on 19 human and animal bone specimens was performed in this study. The results indicate that the precision of pXRF is reliable, but additional work is needed with regard to accuracy. In contrast, the analysis of forty-four prehistoric human and animal bone specimens from varying regions in Peru were used to test the validity of pXRF. The pXRF data support the notion that pXRF is a valid technique to use in the analysis of bone specimens to address archaeological questions regarding paleodiet and possible trade interactions among individuals that reside in the highland and coastal valley regions of Peru

Abstract:

Purpose: The construction industry loses a total of SEK 60 billion annually in the absence of communication. Svensk Byggtjänst has recently released CoClass, which is a new classification system for the construction industry. CoClass is considered to be the solution for the lack of communication and will eventually phase out the existing BSAB96 classification system. CoClass is a modern classification system and is adapted for digital information management. CoClass focuses on buildings' full life cycles, instead of production only as BSAB96 does. This gives rise to many benefits for the end user of the information. The digitization also gives rise to other uses. In order to deepen the knowledge of this system the goal was to compare the advantages of CoClass with BSAB96. In what areas can the system be used and what does it take to fully implement it in the field of work. Method: This final thesis work has contained several methods, also known as method-triangulation, to achieve the goals set up in the beginning of the work. Selected methods for carrying out this work are to work with a case study, where document analysis of published information about CoClass, literature studies about theories regarding the subject, calculations of the cost in real projects and supplementary interviews with the leading actors within the process of developing CoClass are included. Findings: The construction industry is an industry known for its conservative actions, which will also be reflected in the implementation of CoClass. Customers can however claim CoClass as a default in projects which will speed this up. CoClass brings many advantages and will be used in the future with ease. The benefits that the system brings to users varies between actors, but on the other hand, it is possible for everyone in the construction process to utilize benefits in their own niche. Implications: CoClass is a system that is not fully developed at the moment (2018) and therefore has few minor shortcomings. The fact that not more companies have implemented the system in their organizations is mainly due to a more final version, especially when their project "AMA function" has been completed and evaluated. Limitations: This final thesis work only corresponds to the versions of CoClass released in February 2018. The limitations set at the beginning of the work around the analyzed typing rooms discussed more specifically what inside the room would be calculated. The work has focused most around the leading actors within CoClass, which should have the most knowledge about the area. They have mostly been the subject to get information about their implementation-strategies and what they think is needed for it to happen. Keywords: CoClass, BSAB96, Implementation, Classification, BIM, ICT. Syfte: Byggbranschen förlorar årligen sammanlagt 60 miljarder kronor per år i bristande kommunikation. Svensk Byggtjänst har nyligen släppt CoClass som är ett nytt klassifikationssystem för byggbranschen. CoClass anses vara lösningen på problemet med bristande kommunikation och ska så småningom fasa ut det befintliga klassifikationssystemet BSAB96. CoClass är ett modernt klassifikationssystem och är anpassat för digital informationshantering. CoClass riktar in sig på byggnaders fulla livscykler, istället för enbart produktion som BSAB96 gör. Detta ger upphov till många fördelar för slutanvändaren av informationen. Digitaliseringen ger även upphov till andra användningsområden. För att fördjupa kunskaperna kring detta system har målet varit att jämföra fördelarna med CoClass jämfört med BSAB96. Vilka exempel på användningsområden som CoClass kan tillämpas på och vad som krävs för att en fullständig implementering ska ske. Metod: Detta examensarbete innehåller flertalet olika metoder för datainsamling, så kallad metodtriangulering, för att uppnå de mål som sattes upp i början av arbetet. Valda metoder för att genomföra detta arbete har varit att använda en fallstudie, där dokumentanalys av publicerad information kring CoClass, litteraturstudier kring teorier som anknyter till ämnet, beräkningar av kostnader på ett verkligt projekt samt kompletterande intervjuer med de ledande aktörerna kring framtagningen av CoClass ingår. Resultat: Byggbranschen är en bransch känd för sitt konservativa agerande, vilket även kommer återspeglas vid implementeringen av CoClass. Däremot kan beställare kravställa CoClass som standard i projekt, vilket kommer skynda på detta. CoClass bär med sig många fördelar och kommer i framtiden att kunna användas med enkelhet. Fördelarna som systemet bär med sig till användarna riktar sig olika till olika aktörer, däremot finns det möjlighet för samtliga inom byggprocessen att nyttja fördelar på ett eget nischat vis. Konsekvenser: CoClass är ett system som inte är fullt utvecklat för tillfället (2018) och har därför några mindre brister. Att inte fler företag har implementerat systemet i sina organisationer än beror främst på att de väntar på en mer slutgiltig version, främst när deras projekt ”AMA-funktion” har blivit avklarat och utvärderats. Begränsningar: Detta arbete svarar enbart för versionerna av CoClass utgivna under februari 2018. Avgränsningarna som sattes upp i början av arbetet kring de analyserade typrummen behandlade mer specifikt vad i rummet som skulle beräknas. Arbetet har även nischat sig kring de ledande aktörerna för CoClass när det gäller frågeställning 3 om implementering. Nyckelord: CoClass, BSAB96, Implementering, Klassificering, BIM, ICT.

Abstract:

This thesis was developed to investigate the current models of sustainable development and architectural working and design practice and process to respond to the challenges of the current era defined as the Information Age. This thesis proposes a new model of sustainable development aligned to architecture and the Information Age, and a new integrated systems-design methodology to support it. Buildings were defined by le Corbusier in 1927 as ‘machines for living in’1 on the premise that these buildings facilitated our day-to-day user experience. The role of architecture as a facilitator for a sustainable existence is therefore subject to continued investigation. While there has been an increasing interest in environmental issues and ‘green building’, built environments have consequently failed to effectively holistically integrate core sustainable development principles in architecture. When compared to the definition of sustainable development in the UN Brundlandt Report of 1987, further research into an architectural design methodology is required to enable and plan for the long-term success of our built environments for current and, importantly, future generations. The practices and production of architecture risk being limited to reactively monitoring the design and construction processes for fixed moments in time, usually after the problem has presented itself. This is representative of localised, yet much publicised trends involving quantifiable rating systems for building performance. This does not contribute to long-term sustainability of the architectural product, nor the core principle of sustainable development to adequately meet the needs of current and future generations. The gravitation towards these easily-followed, yet limited-in-scope checklist processes is symptomatic of concepts of sustainable development remaining too broad and fragmented to facilitate focused, industry-appropriate implementation and design. The digital and information-based revolution has arrived, and humankind has now progressed to the point where constant and pervasive access to information and communication in a world of connected systems has changed the way we live and work. This is occurring at an exponential rate within what have been termed ‘knowledge-based societies’. Furthermore, the influence of the Information Age continues to manifest itself in the built environment through advancement of concepts and initiatives such as Smart Cities, intelligent buildings, and the Internet of Things. However, architectural approach and its emphasis on the building as a finite product comes at the expense of a holistic and integrated systems approach, and therefore requires investigation towards a revised design methodology. This thesis will begin by investigating the concept of sustainable development from its original inception to existing interpretations, and will interrogate its continued significance as a decades-old concept to the Information Age. This will be undertaken on the basis that sustainable development primarily aligns itself to the needs of humankind (current and future generations) and as such remains timeless as a core concept. However, the criteria that define sustainable development require investigation based on: a) their suitability towards human need in the context of knowledge-based societies and the Information Age, as well as b) their appropriateness for focused implementation in the scope of the built environment. In this aim, newly proposed criteria will be assimilated into a revised model for sustainable development, from which a methodology for design is developed. This will address the nature of the architectural process towards the creation of sustainable building solutions as a function of a systems approach, rather than a product approach. An integrated systems-design methodology is proposed, promoting the evolution of sustainable development theory in architecture for greater applicability to the Information Age. This systems-design methodology proactively identifies criteria for solving a given problem and the development of alternative solutions, while the proposed revised model for sustainable development is integrated to achieve a holistic building solution based on a systems process. This is inclusive of product (systems solution) delivery into the operation phase. The designer and project information model therefore transition into ‘information custodian’ and repository for knowledge gathering and exchange respectively, to the benefit of current and future stakeholders. This is addressed through various stages in design development and implementation, which apply contextually-based requirements of proposed sustainable development criteria, while catering for aspects of future flexibility, user experience, and knowledge-based development. This methodology expects the design practitioner to apply multi-dimensional evaluation and assessment tools at their discretion, and accommodate changing project dynamics over its life cycle. This implementation will benefit from future research and the introduction of new technologies to aid the process. This may furthermore be affected by new regulatory policy and guidelines affecting architects and the built environment. Thesis (PhD)--University of Pretoria, 2018. Architecture PhD Unrestricted

Abstract:

Since 2009, within the framework of the Ánimas Altas Archaeological Program in Ica, Peru — under the direction of the au-thors — systematic excavations have been carried out in the Ánimas Altas/Ánimas Bajas archaeological complex, the center ofthe Paracas culture in the lower Ica valley. To date, the project has documented public-ceremonial architecture as well as domesticand production areas. Additionally, excavations have revealed evidence of pyramidal complexes contiguous to plazas, one smallpyramid housing an elite tomb decorated with a mural frieze, and remnants of dwellings and storage areas.In this article, we attempt to understand the function that Ánimas had during its prehispanic occupation, using data from recent excavations at the site. Our analysis draws on a wide range of material culture categories to facilitate reflections on the concepts of ‘city’ and ‘territory’ in the Andes, enriching our understanding of the process of prehispanic urbanism, a widely debated concept among Andeanists. Thus, we explore the meaning of the stylistic and technological heterogeneity observde in some types of materialamong Andeanists. Thus, we explore the meaning of the stylistic and technological heterogeneity observde in some types of materia culture, positing the idea that this heterogeneity reflects social and territorial dynamics, rather than mere diachronic variation. Desde 2009, en el marco del Programa Arqueológico Ánimas Altas, Ica, Perú, bajo la dirección de los autores, se realizan exca-vaciones sistemáticas en el complejo arqueológico Ánimas Altas/Ánimas Bajas, principal establecimiento paracas en el valle bajode Ica. Hasta la fecha, se han documentado áreas público-ceremoniales, y otras de carácter doméstico y/o de producción. Además,las excavaciones han revelado secciones de complejos piramidales contiguos a plazas, una pequeña pirámide que albergaba unatumba de élite asociada a un friso mural y vestigios de viviendas y áreas de almacenaje.En el presente artículo, sobre la base de los datos proporcionados por las recientes excavaciones, intentamos aproximarnos al tipo de establecimiento que habría sido Ánimas. Se enfatizan los análisis de la cultura material para alimentar la reflexión sobre la noción de la ciudad y del territorio en los Andes, y enriquecer la problemática del urbanismo prehispánico, tema muy debatido en el Perú. Asimismo, se explora el significado de la heterogeneidad estilística y tecnológica de algunos aspectos de la cultura material dentro una perspectiva de dinámicas sociales y territoriales, en lugar de considerarla automáticamente como una manifestación dentro una perspectiva de dinámicde evolución estilística diacrónica.

Abstract:

The burial area BRiG 3117 (Coyungo) was investigated during the PABRiG (Proyecto Arqueológico Bajo Río Grande). It consists of four burial contexts with about 25 individuals (MNI) and a considerable amount of pottery, textiles and gourd fragments among others. One of the textiles is part of a famous piece housed at Dumbarton Oaks. It is the most significant and complex compound known from the south coast during Late Formative times despite its heavy previous looting. In this paper the material evidence is presented in a preliminary form and some concerning interpretations are offered.

Abstract:

Réseau centré sur l’information (ICN) englobe une famille de réseaux architectures repensant les principes de communication Internet autour des données nommées. Après plusieurs années de recherche et l’émergence de quelques propositions populaires, l’idée de remplacer TCP / IP par un réseau centré sur les données reste débattue. Les avantages du ICN ont été préconisés dans le contexte des réseaux 5G pour la prise en charge de schémas de communication minimaux hautement mobiles, à accès multiples / source et à latence. Toutefois, des tests à grande échelle et une insertion dans des réseaux opérationnels doivent encore être réalisés, probablement en raison de l'absence d'une stratégie de déploiement incrémental claire. L'objectif de cette thèse est de proposer et d'évaluer des solutions efficaces pour le déploiement de l'ICN. Tout d'abord, nous proposons Hybrid-ICN (hICN), une intégration ICN dans IP (plutôt que sur / sous / à la place de) qui a pour ambition de ne pas échanger les principes architecturaux ICN. En réutilisant les formats de paquets existants, hICN introduit de l'innovation au sein de la pile IP, nécessitant un minimum de mises à niveau logicielles et garantissant une interconnexion transparente avec les réseaux IP existants. Deuxièmement, la thèse est centrée sur le problème du déploiement de l'ICN aux extrémités du réseau, notamment l'hôte final, en concevant une infrastructure de transport et une API de socket pouvant être utilisées dans plusieurs architectures ICN telles que NDN, CCN et hICN. Le cadre favorise les technologies de pointe visant à fournir des performances et une efficacité aux applications. Une analyse comparative détaillée à la fin du chapitre présentera les performances du cadre de transport. Ensuite, les avantages que les services de transport et de réseau hICN peuvent apporter aux applications seront évalués en considérant deux principaux cas d'utilisation: HTTP et WebRTC. Le premier représente le protocole de facto du Web, tandis que le second est une nouvelle technologie émergente de plus en plus adoptée pour les services en temps réel. Enfin, la thèse propose une solution pour déployer par programmation, configuration et gestion des réseaux et des applications ICN: Virtualized ICN (vICN), un cadre unifié programmable pour la configuration et la gestion de réseau qui utilise les progrès récents en matière d’isolement des ressources et de techniques de virtualisation. Il offre une plate-forme unique, flexible et évolutive pour répondre à différents objectifs, en particulier les déploiements réels de l'ICN dans les réseaux IP existants Information-Centric Networking (ICN) embraces a family of network architectures rethinking Internet communication principles around named-data. After several years of research and the emergence of a few popular proposals, the idea to replace TCP/IP with data-centric networking remains a subject of debate. ICN advantages have been advocated in the context of 5G networks for the support of highly mobile, multi-access/source and latency minimal patterns of communications. However, large-scale testing and insertion in operational networks are yet to happen, likely due to the lack of a clear incremental deployment strategy. The aim of this thesis is to propose and evaluate effective solutions for deploying ICN. Firstly, we propose Hybrid-ICN (hICN), an ICN integration inside IP (rather that over/ under/ in place of) that has the ambition to trade-off no ICN architectural principles. By reusing existing packet formats, hICN brings innovation inside the IP stack, requiring minimal software upgrades and guaranteeing transparent interconnection with existing IP networks. Secondly, the thesis focuses on the problem of deploying ICN at the network endpoints, namely at the end host, by designing a transport framework and a socket API that can be used in several ICN architectures such as NDN, CCN and hICN. The framework fosters cutting-edge technologies aiming at providing performance and efficiency to applications. An extensive benchmarking at the end of the chapter will present the performance of the transport framework. Subsequently, the benefits that hICN network and transport services can bring to applications will be assessed, by considering two main use cases: HTTP and WebRTC. The former represents the de-facto protocol of the Web, while the latter is a new emerging technology increasingly adopted for real time services. At last, the thesis proposes a solution for programmatically deploying, configuring and managing ICN networks and applications: Virtualized ICN (vICN), a programmable unified framework for network configuration and management that uses recent progresses in resource isolation and virtualization techniques. It offers a single, flexible and scalable platform to serve different purposes, in particular the real deployments of ICN in existing IP networks

Abstract:

A partir des limites réelles de l'Internet, dans cette thèse, nous étudions différents aspects de deux directions dont l'Internet évolue. En particulier, nous considérons des moyens plus souples pour joindre les hôtes du réseau, et pour distribuer du contenu. Host Centric Networking (HCN) est le nom que nous donnons à l'ensemble des architectures qui tentent de découpler la position et l'identification d'un hôte. Fondamentalement, ils identifient chaque nœud par des étiquettes plates qui ne localisent pas l'hôte dans le réseau. Les architectures HCN utilisent Distributed Hash Tables ( DHT ) pour récupérer la position de l'hôte de l'étiquette correspondante.Toutefois, l'acheminement et la transmission sous-jacente à la DHT, s'appuient fortement sur des algorithmes traditionnels basés sur des chemins uniques. Ainsi, dans la première partie, nous proposons APLASIA, une architecture de routage alternatif composé principalement par un algorithme de recherche de chemin, à savoir APL, et par un plan de données de autoforwarding. Information Centric Networking (ICN) rend le contenu directement adressable par les hôtes du réseau. L'idée de base consiste à envoyer des paquets portant l'identifiant de contenu, plutôt que l'adresse de l'hôte. Comme le contenu peut être facilement mis en cache dans les périphériques réseau, un réseau ICN peut être modélisée comme un réseau de caches orienté vers le récepteur. Dans la deuxième partie de ce travail, nous considérons la mise en oeuvre des algorithmes déployés sur un réseau de caches Starting from the evidence of the Internet’s actual limits, in this Thesis we investigate different aspects of two directions the Internet is evolving toward. In particular, we consider more flexible ways to reach hosts, and to distribute content. Host Centric Networking (HCN) is the name we give to the umbrella architectures which try to decouple host location and identifiers. Basically, they identify each device by the means of flat labels which do not locate the host within the network. HCN architectures leverage Distributed Hash Table(DHT) approaches for retrieving the host position from the corresponding label. However, routing and forwarding underlying the DHT, heavily rely on traditional single path algorithms. Thus, in the first part we propose APLASIA, an alternative routing architecture mainly composed by a path-finding algorithm, namely APL, and by an autoforwarding data plane. Information Centric Networking (ICN) makes content directly addressable by network hosts. The basic idea is to send packets carrying the content identifier, rather than the host address. As content can be easily cached within network devices, an ICN network can be modeled as a receiver driven network of caches. Indeed, in the second part of this work, we consider caching algorithms deployed over a network of caches. Each of these algorithms is a triplet composed by forwarding (which path is worth following), meta-caching (what content is worth caching), and replacement (what content is worth replacing) strategies

Abstract:

Cerrillos is an Early to Middle Paracas civic-ceremonial site located in the upper Ica Valley of Perú. The site is known for its finely plastered adobe architecture, beautifully decorated ceramics, and complex textiles, many of which are decorated with camelid hair. Cerrillos was located in a strategically important place where the mountains meet the coastal desert and the Ica River bends south, a likely intersection in a road system that connected Cerrillos to contemporary sites in the Paracas region and beyond. This paper focuses on several early textiles, ceramics, and other artifacts, including ceramic palettes used for gold working and wooden earspools, that suggest that Cerrillos was involved in a cultural phenomenon or interaction sphere that linked sites as far away was Chavín de Huántar through the interchange of goods, beliefs, and practices. The paper presents a complete description of the textiles excavated at Cerrillos between 1999 and 2002, focusing on two fabric fragments with images of the Staff Deity and one with an abstract Chavín-like design. The ceramics discussed in the text demonstrate the wide variety of styles found at Cerrillos, including some that resemble the Janabarriu of Chavín de Huántar and several others that are either not Paracas or an Early Paracas style that has never been previously described. Cerrillos es un sitio cívico-ceremonial con ocupación entre las épocas Paracas Temprano y Medio, localizado en el valle alto de Ica, Perú. Es conocido por su arquitectura de adobe enlucida de manera fina, cerámica bellamente decorada y textiles complejos, muchos de ellos decorados con fibra de camélido. Estuvo localizado en un lugar de importancia estratégica, donde las montañas se encuentran con el desierto costero y el río Ica gira hacia el sur, una probable intersección en un sistema de caminos que lo conectaba con sitios contemporáneos en la región de Paracas y más allá. Este artículo se enfoca en diversos textiles, cerámica y otros artefactos tempranos, entre ellos paletas de cerámica usadas para trabajar el oro y aretes en forma de argollas de madera, lo que sugiere que este complejo estaba involucrado en un fenómeno cultural o esfera de interacción que vinculaba sitios tan lejanos como Chavín de Huántar mediante el intercambio de bienes, creencias y prácticas. Este artículo presenta una completa descripción de los textiles excavados en Cerrillos entre 1999 y 2002, y se enfoca en dos fragmentos textiles, uno con imágenes del Dios de las Varas y el otro con un diseño abstracto parecido al chavín. La cerámica tratada en el texto demuestra la amplia variedad de estilos encontrados, entre ellos algunos que se parecen al Janabarriu de Chavín de Huántar y varios otros que no corresponden al estilo Paracas o que semejan un estilo Paracas Temprano que nunca antes ha sido descrito.

Abstract:

La refrigeració manté la qualitat sensorial del productes i minimitza la pèrdua en les cadenes de valor del fred. Les àrees remotes dels països en desenvolupament es caracteritzen principalment pels baixos nivells de tecnologia, accés limitat a la xarxa elèctrica i el predomini de les petites explotacions agrícoles com un desafiament. El principal objectiu d'aquesta tesi és desenvolupar i caracteritzar un sistema de refrigeració modular multipropòsit basat en l'emmagatzematge de gel per a aplicacions de petita escala. El sistema d'emmagatzematge de gel va utilitzar un equip de refrigeració amb un compressor de corrent continu i velocitat variable. La càrrega de refrigerant i les dimensions de l'tub capil·lar es van optimitzar experimentalment per maximitzar el rendiment i evitar la caiguda de temperatura de la línia de succió. A més, es va avaluar experimentalment el rendiment de sistema sota diversos paràmetres. Els usos de l'emmagatzematge de gel per a refrigeració de llet i aplicacions de càmeres frigorífiques també es van investigar experimentalment. Es van utilitzar deposits de llet convencionals en un bany de refredament aïllat, i en una cambra frigorífica dotada d'una unitat de fancoil amb els seus respectius sistemes experimentals. En general, el treball de recerca realitzat en aquesta tesi aporta més coneixements sobre el desenvolupament de tecnologies de refrigeració baixes en carboni adequades per a països en desenvolupament. La refrigeración mantiene la calidad sensorial del producto y minimiza la pérdida en las cadenas de valor del frío. Las áreas remotas de los países en desarrollo se caracterizaron principalmente por bajos niveles de tecnología, acceso limitado a la red eléctrica y el predominio de las pequeñas explotaciones agrícolas como un desafío. El principal objetivo de esta tesis es desarrollar y caracterizar un sistema de refrigeración modular multipropósito basado en el almacenamiento de hielo para aplicaciones de pequeña escala. El sistema de almacenamiento de hielo utilizó un equipo de refrigeración con un compresor de corriente continua y velocidad variable. La carga de refrigerante y las dimensiones del tubo capilar se optimizaron experimentalmente para maximizar el rendimiento y evitar la caída de temperatura de la línea de succión. Además, se evaluó experimentalmente el rendimiento del sistema bajo diversos parámetros. Los usos del almacenamiento de hielo para refrigeración de leche y aplicaciones de cámaras frigoríficas también se investigaron experimentalmente. Se utilizaron cantaras de leche convencionales en un baño de enfriamiento aislado, y en una cámara frigorífica dotada de una unidad de fancoil con sus respectivos sistemas experimentales. En general, el trabajo de investigación realizado en esta tesis aporta más conocimientos sobre el desarrollo de tecnologías de refrigeración bajas en carbono adecuadas para países en desarrollo. Refrigeration and cooling maintains the sensory quality of the product and minimizes the loss in cold value chains. Remote areas of the developing countries were mainly characterized by low levels of technology, limited access to modern energy and dominance of small-holder farms as a challenge. Hence, the main objective of this thesis is to develop and characterize a modular-multipurpose cooling system based on an ice-storage for small-scale applications. As part of the experimental system, the ice storage with a variable speed DC-compressor was developed and fabricated. The refrigerant charge and the capillary tube dimensions were experimentally optimized to maximize performance and avoid suction line temperature drop. Moreover, performance of the system under varying parameters was evaluated. Uses of the ice storage for milk cooling and cold room applications were also experimentally investigated. Conventional milk-cans with insulated box and a heat simulated room with a FCU were utilized as respective experimental systems. Chilled water recirculation rates, ice-storage energy density, and air flow rate across FCU were varied as main experimental parameters. Improvement of the ice production technique and corresponding performance data obtained were among main contributions of this research. In general, the research work performed in this thesis contributes more knowledge on development of low-carbon cooling technologies suitable for developing countries. Therefore, piloting and field testing of the technology are among major recommendations for future work.

Abstract:

La communication Machine-to-Machine (M2M) est l'un des principaux fondements de l'Internet des Objets (IoT). C'est un phénomène qui a évolué discrètement au cours du temps et vient d’émerger à la surface pour do! nner naissance à une explosion de nouveaux usages et services. Capteurs, actionneurs, tags, véhicules et objets intelligents ont tous la possibilité de communiquer. Le nombre de connexions M2M est en constante augmentation et il est prévu de voir des milliards d’objets connectés dans un futur proche. Les applications M2M offrent des avantages dans divers domaines à savoir les villes intelligentes, les voitures connectées, les usines du futures, l’agriculture de précision, l’environnement, la santé, etc. La croissance rapide de cet écosystème est entrain de conduire le M2M vers un avenir prometteur. Cependant, les opportunités d'expansion des marchés M2M ne sont pas évidentes. En effet, un ensemble de challenges doivent être surmontés afin de permettre un déploiement à grande échelle dans des domaines diverses et variés à savoir les défis d’interopérabilité, de complexité et de scalabilité. Actuellement, le marché du M2M souffre d'une fragmentation verticale importante touchant la majorité des domaines industriels. En effet, diverses solutions propriétaires ont été conçues pour répondre à des applications spécifiques engendrant ainsi un sérieux problème d''interopérabilité. Pour adresser ce challenge, nous avons conçu, développer et expérimenté la plateforme OM2M offrant une architecture opérationnelle, flexible et extensible pour l'interopérabilité M2M conforme à la norme SmartM2M. Pour supporter les environnements contraints, nous avons proposé une nouvelle convention de nommage basée sur une structure de ressources non-hiérarchique permettant d’optimiser la taille des messages échangés. Pour assurer l’interopérabilité sémantique entre les applications et les machines, nous avons proposé l'ontologie IoT-O. Cette dernière est composée de cinq modèles de base représentant les capteurs, les actionneurs, les observations, les actuations et les web ! services pour permettre de converger rapidement vers un vocabulaire commun pour l'IoT. Une plateforme M2M horizontale permet d'interconnecter des machines hétérogènes largement distribués et qui évoluent fréquemment en fonction des changements de l’environnement. Maintenir ces systèmes complexes en vie est coûteux en termes de temps et d'argent. Pour adresser ce challenge, nous avons conçu, développé et intégré le framework FRAMESELF afin d'ajouter des capacités d'autogestion aux systèmes M2M basées sur le paradigme de l'informatique autonome. En étendant le modèle d'architecture de référence MAPE-K, notre solution permet d'adapter dynamiquement le comportement de la plateforme OM2M par en fonctions des changements du contexte et des politiques haut niveaux. Nous avons défini un ensemble de règles sémantiques pour faire du raisonnement sur l'ontologie IoT-O en tant que modèle de connaissance. Notre objectif est de permettre la découverte automatique entre les machines et les applications à travers un appariement sémantique et une reconfiguration dynam! ique de l'architecture des ressources. L’interopérabilité et l’autogestion ouvrent la voie à un déploiement de masse des systèmes M2M. Par contre, ces derniers se basent sur l'infrastructure actuelle d'internet qui n'a jamais été conçu pour ce genre de d'utilisation ce qui pose de nouvelles exigences en termes de scalabilité. Pour adresser ce challenge, nous avons conçu, simulé et validé l'approche OSCL proposant une nouvelle topologie de réseau maillé M2M comme alternative à l'approche centralisée actuelle. OSCL s'appuie sur les techniques de routage centrées sur l'information favorisant les communications à sauts multiples et un cache distribué pour une meilleure dissémination des données. Nous avons développé le simulateur OSCLsim pour valider l'approche proposée.[...] Machine-to-Machine (M2M) is one of the main features of Internet of Things (IoT). It is a phenomenon that has been proceeding quietly in the background, and it is coming into the surface, where explosion of usage scenarios in businesses will happen. Sensors, actuators, tags, vehicles, and intelligent things all have the ability to communicate. The number of M2M connections is continuously increasing, and it has been predicted to see billions of machines interconnected in a near future. M2M applications provide advantages in various domains from smart cities, factories of the future, connected cars, home automation, e-health to precision agriculture. This fast-growing ecosystem is leading M2M towards a promising future. However, M2M market expansion opportunities are not straightforward. A set of challenges should be overcome to enable M2M mass-scale deployment across various industries including interoperability, complexity, and scalability issues. Currently, the M2M market is suffering from a high vertical fragmentation affecting the majority of business sectors. In fact, various vendor-specific M2M solutions have been designed independently for specific applications, which led to serious interoperability issues. To address this challenge, we designed, implemented, and experimented with the OM2M platform offering a flexible and extensible operational architecture for M2M interoperability compliant with the SmartM2M standard. To support constrained environments, we proposed an efficient naming convention relying on a non-hierarchical resource structure to reduce the payload size. To reduce the semantic gap between applications and machines, we proposed the IoT-O ontology for an effective semantic interoperability. IoT-O consists of five main parts, which are sensor, actuator, observation, actuation and service models and aims to quickly converge to a common IoT vocabulary. An interoperable M2M service platform enables one to interconnect heterogeneous devices that are widely distributed and frequently evolving according to their environment changes. Keeping M2M systems alive is costly in terms of time and money. To address this challenge, we designed, implemented, and integrated the FRAMESELF framework to retrofit self-management capabilities in M2M systems based on the autonomic computing paradigm. Extending the MAPE-K reference architecture model, FRAMESELF enables one to dynamically adapt the OM2M system behavior according to high level policies how the environment changes. We defined a set of semantic rules for reasoning about the IoT-O ontology as a knowledge model. Our goal is to enable automatic discovery of machines and applications through dynamic reconfiguration of resource architectures. Interoperability and self-management pave the way to mass-scale deployment of M2M devices. However, current M2M systems rely on current internet infrastructure, which was never designed to address such requirements, thus raising new requirements in term of scalability. To address this challenge, we designed, simulated and validated the OSCL overlay approach, a new M2M meshed network topology as an alternative to the current centralized approach. OSCL relies on the Named Data Networking (NDN) technique and supports multi-hop communication and distributed caching 5 to optimize networking and enhance data dissemination. We developed the OSCLsim simulator to validate the proposed approach. Finally, a theoretical model based on random graphs is formulated to describe the evolution and robustness of the proposed system

Abstract:

Parmi les architectures orientées contenu, l'architecture NDN (Named-Data Networking) a su agréger la plus importante communauté de chercheurs et est la plus aboutie pour un Internet du futur. Dans le cadre de l'architecture NDN, au cours de ce doctorat, nous nous sommes concentrés sur les mécanismes de routage adaptés à cette nouvelle vision du réseau. En effet, la capacité à acheminer une requête vers la destination est fondamentale pour qu'une architecture réseau soit fonctionnelle et cette problématique avait été très peu étudiée jusqu'alors. Ainsi, dans ce manuscrit, nous proposons le protocole de routage SRSC (SDN-based Routing Scheme for CCN/NDN), qui repose sur l'utilisation du paradigme des réseaux logiciels (Software-Defined Networks\\, SDN). SRSC utilise un contrôleur capable de gérer le plan de contrôle du réseau NDN. En centralisant l'ensemble des informations telles que la topologie du réseau, la localisation des différents contenus et le contenu des mémoires cache des nœuds du réseau, le contrôleur va pouvoir établir la meilleure route pour acheminer les requêtes vers le contenu. SRSC permet également un routage de type anycast, c'est à dire qu'il permet d'acheminer les requêtes vers le nœud le plus proche qui dispose des données, permettant d'optimiser la distribution des requêtes dans le réseau et de répartir la charge parmi tous les nœuds. De plus, SRSC utilise uniquement les messages Interest et Data de l'architecture NDN et tient son originalité du fait qu'il s'affranchit complètement de l'infrastructure TCP/IP existante. Dans un premier temps, SRSC a été évalué via simulation avec le logiciel NS-3 où nous l'avons comparé à la méthode d'inondation des requêtes, appelée flooding, initialement proposée par NDN. SRSC a ensuite été implanté dans NDNx, l'implantation open source de l'architecture NDN, puis déployé sur notre testbed utilisant la technologie Docker. Ce testbed permet de virtualiser des nœuds NDN et d'observer un réel déploiement de cette architecture réseau à large échelle. Nous avons ainsi évalué les performances de notre protocole SRSC sur notre testbed virtualisé et nous l'avons comparé au protocole NLSR, (Named-Data Link State Routing Protocol), le protocole de routage du projet NDN Internet is a mondial content network and its use grows since several years. Content delivery such as P2P or video streaming generates the main part of the Internet traffic and Named Data Networks (NDN) appear as an appropriate architecture to satisfy the user needs. Named-Data Networking is a novel clean-slate architecture for Future Internet. It has been designed to deliver content at large scale and integrates several features such as in-network caching, security, multi-path. However, the lack of scalable routing scheme is one of the main obstacles that slow down a large deployment of NDN at an Internet-scale. As it relies on content names instead of host address, it cannot reuse the traditional routing scheme on the Internet. In this thesis, we propose to use the Software-Defined Networking (SDN) paradigm to decouple data plane and control plane and present SRSC, a new routing scheme for NDN based on SDN paradigm. Our solution is a clean-slate approach, using only NDN messages and the SDN paradigm. We implemented our solution into the NS-3 simulator and perform extensive simulations of our proposal. SRSC show better performances than the flooding scheme used by default in NDN. We also present a new NDN testbed and the implementation of our protocol SRSC, a Controlled-based Routing Scheme for NDN. We implemented SRSC into NDNx, the NDN implementation, and deployed it into a virtual environment through Docker. Our experiments demonstrate the ability of our proposal to forward Interest, while keeping a low computation time for the Controller and low delay to access Content. Moreover, we propose a solution to easily deploy and evaluate NDN network, and we compare SRSC with NLSR, the current routing protocol used in NDNx

Abstract:

La Côte Nord de l’Estuaire et du Golfe du St. Laurent (Québec, Canada) est caractérisée par une série de complexes deltaïques mis en place en contexte de chute de Niveau Marin Relatif (NMR) forcée par le rebond glacio-isostatique, lors du retrait des marges de l’Inlandsis Laurentidien. L’étude de trois complexes deltaïques montre qu’un motif d’évolution morphostratigraphique contrôlé par le retrait des marges glaciaires prévalait au premier ordre. Le premier stade de sédimentation se caractérise par la mise en place de cônes d’épandage juxtaglaciaires sous-aquatiques. Leur localisation au front de la marge glaciaire fait que la répartition spatiale des corps sédimentaires montre localement un empilement en rétrogradation. Dès l’émergence d’un front glaciaire continental, des deltas proglaciaires se développent en contexte de chute de NMR, formant des lobes dont l’altitude décroît vers le bassin. Ces derniers sont initialement associés à un système fluviatile en tresse alimenté en sédiments glaciogéniques par les marges glaciaires en retrait. Malgré des taux de chute de NMR de plusieurs cm/an, aucune incision fluviatile n’est observée à ce stade et la dynamique de transfert est prédominante du fait des forts taux d’apports sédimentaires. Plus tard, à la suite du retrait des marges glaciaires hors des bassins versants, le remaniement paraglaciaire se développe du fait de la réduction drastique des apports en eaux et sédiments. Le système fluviatile, devenu méandriforme, s’encaisse dans les anciens dépôts deltaïques maintenant inactifs et les bordures de deltas sont remaniées par les processus littoraux (plages soulevées, terrasses marines). Cette étude révèle que la majorité du volume de ces complexes deltaïques (10-20 km3) est mis en place en quelques milliers d’années seulement, immédiatement après la déglaciation ; le remaniement paraglaciaire n’ayant contribué à l’accrétion deltaïque que très marginalement. La modélisation numérique (Dionisos) valide les différents forçages identifiés par l’analyse morphosédimentaire. Une synthèse des complexes deltaïques à l’échelle de toute la Côte Nord du St. Laurent a permis de catégoriser 21 complexes deltaïques en 4 scénarios d’évolution morphosédimentaire, directement liés à la dynamique de retrait de la marge glaciaire. Leur décryptage offre une clef de lecture originale pour l’historique du retrait des marges glaciaires de l’Inlandsis Laurentidien sur la période 12-7.5 ka cal BP The North Shore of the St. Lawrence Estuary and Gulf is characterized by the presence of deltaic complexes that were emplaced under falling Relative Sea Level (RSL) forced by the glacio-isostatic rebound, immediately after the retreat of the Laurentide Ice Sheet (LIS) margin. The study of three deltaic complexes reveals that a common morphostratigraphic evolution forced by the retreat of the LIS prevailed for the edification of these structures, reflecting the retreat of the LIS margin. The emplacement of subaqueous outwash fans beyond the retreating or stillstanding glaciomarine margin constitutes the first stage of this evolution. As tied to the ice-margin position, these fans are characterized in places by a backstepping stacking pattern, in spite of the forced regressive setting. From the emergence of a continental ice front, the proglacial deltaic system develops and forms lobes staged accordingly to the RSL fall. These deltaic systems actively prograde at that time because they are fed in glaciogenics by the retreating LIS margin through braided meltwater streams. In spite of the RSL fall reaching several centimeters per years, no fluvial entrenchment occurs mainly owing to the significant amount of sediment supply. Later, when the LIS margin retreats from the drainage basins of feeding rivers, fluvial systems experience a drastic drop in sediment supply that forced the interruption of the deltaic progradation and the onset of paraglacial reworking. The paraglacial reworking consists in the entrenchment of a meandering fluvial system within former deltaic deposits and shows the prevalence of shallow-marine processes (waves, tides) at the delta rim (raised beaches, marine terraces). This study reveals that the bulk of the deltaic volume (c.a. 10-20 km3) for each complex was emplaced in only a few thousands of years following the LIS margin retreat when the latter was still located in the drainage basin. The paraglacial reworking had a minor influence on the deltaic accretion. A forward stratigraphic model (Dionisos) is used to validate the variety of forcing as understood from the sedimentary analysis. A synthesis including 21 deltaic complexes of the St. Lawrence North Shore allowed the establishment of a fourfold categorization. This scheme of deltaic evolution was used in order to refine the position of the LIS margin retreating upland for a period ranging from 12 to 7.5 ka cal BP
