Mendoza, Toro Paola Carolina. "Evaluación de viabilidad de replicar el modelo de la campaña: Australian made australian grown en Chile." Tesis, Universidad de Chile, 2014. http://www.repositorio.uchile.cl/handle/2250/116401.

Abstract:
Magíster en Gestión para la Globalización<br>El objetivo de la investigación es determinar si es posible replicar exitosamente en Chile una campaña similar a Australian Made Australian Grown (AMAG), iniciativa desarrollada en Australia que tiene por objeto principal promover el consumo de los productos elaborados o cultivados en dicho país. Para lograr este objetivo, se realiza un análisis de la campaña australiana, tanto a nivel interno, considerando la historia, su desarrollo, funcionamiento y ámbitos de acción, así como también análisis externo, identificando qué factores han sido y son claves a lo largo de los años. A partir de lo anterior, y realizando una comparación con la situación existente en Chile, se determina si es viable o no implementar una iniciativa similar a AMAG, en nuestro país. Por tanto, a partir del análisis de la iniciativa australiana, se busca identificar cuáles son los factores críticos de éxito que están presentes, ya sea al momento de poner en marcha el proyecto y/o durante su desarrollo, y que deben estar presentes en una futura implementación en Chile, de tal forma de mantener la efectividad del trabajo de la iniciativa. Estos factores de éxito se refieren a situaciones o condiciones específicas directa o indirectamente relacionadas a la iniciativa y que le han permitido a esta organización mantenerse por más de 25 años en funcionamiento y es ahí donde radica la importancia de su identificación. En definitiva, al término de este trabajo se concluye que las condiciones que harían factible implementar en Chile una campaña similar a lo realizado por AMCL en Australia, son: desarrollar y posicionar un logo que sea representativo y de fácil asociación con Chile; contar con una campaña u organización única que concentre esfuerzos y recursos; implementar campañas en mercado interno para posicionar a la campaña en este mercado y fortalecer en el mensaje el sentido colectivo que ésta tiene detrás; desarrollar el trabajo con perspectivas de largo plazo; contar con apoyo y respaldo del gobierno y también de asociaciones de privados, de los grandes minoristas y también de los gobiernos locales. Lo anterior, constituye la base para que se comience a trabajar en el diseño y definiciones de una campaña de este tipo, tales como: objetivo, misión, visión, oferta de valor y, estrategia, así como también en la definición de un plan de trabajo para su implementación. Hasta ahora el gobierno chileno ha cumplido el rol estratégico de apoyo y respaldo en la tarea de posicionar al país y sus productos en los mercados extranjeros, sin embargo, aún persiste una brecha de la institucionalidad chilena para la implementación de iniciativas que apunten a cumplir con este objetivo. Dicha brecha se refiere a la independencia y autonomía en la toma de decisiones con que ha contado la organización australiana, que también ha sido capaz de autofinanciarse, aspecto en que las instituciones chilenas investigadas, aún están lejos de lograrlo. En este mismo sentido, resulta muy relevante y primordial para el éxito de una campaña de este tipo, definir la imagen con la que dar a conocer a Chile, la que deberá ser única, representativa, distintiva y de rápida asociación con el país, tal como ocurre con el logo de la campaña australiana que resume todo lo anterior.

Abstract:
TESIS PARA OPTAR AL GRADO DE MAGÍSTER EN POLÍTICAS PÚBLICAS<br>Ante la creciente proporción de egresados de Educación Media Técnico-Profesional (EMPT) que rinde la Prueba de Selección Universitaria (PSU) en Chile, y luego opta por seguir estudios superiores, se ha desarrollado una línea creciente de investigación sobre la relación entre EMTP y la PSU, la cual permita, más allá del consenso de que estudiar EMTP tiene un efecto negativo respecto de escoger la modalidad científico-humanista (EMCH) asociada a las diferencias socioeconómicas, identificar el efecto atribuíble a la formación diferenciada. Uno de los problemas para responder a esta interrogante es resolver el problema de sesgo de selección, puesto que quienes ingresan a las dos modalidades o entre los que ingresan a EMTP y deciden rendir la PSU son diferentes, tanto en atributos observados como no observados, la cual posiblemente sobreestime el efecto estimado no corregido. En este estudio buscamos aislar y determinar el efecto en la PSU de cursar en EMTP respecto a hacerlo en EMCH, tanto para el ciclo diferenciado como para toda la enseñanza media, a través de modelos de regresión Heckman en dos etapas, controlando por variable instrumental relacionada con la probabilidad de rendir la PSU. A través del seguimiento de una cohorte de alumnos que rindieron el SIMCE de 8º básico en 2011, el de 2º Medio en 2013 y la PSU en 2015, se puede calcular de forma aislada el efecto de los dos años de formación diferenciada y de los cuatro años en la modalidad de enseñanza media escogida por cada estudiante. Además, buscamos saber si esta tendencia negativa en EMTP logra ser revertida, y en qué magnitud, entre aquellos estudiantes que se matriculan en establecimientos TP de no muy alta selectividad académica en su ingreso, pero de destacado SIMCE en 2º medio, los cuales fueron denominados como “Liceos TP Efectivos en SIMCE” Complementando con la ejecución de los mismos modelos en MCO, el análisis de correlaciones y estadísticas descriptivas, se obtiene que el ciclo diferenciado tiene un efecto negativo de 24 puntos menos para EMTP, y de 27 menos para los cuatro años de EMTP a nivel general, siendo relativamente menos perjudicada la rama Comercial y más la rama Técnica-Servicios. Por último, los Liceos TP considerados “Efectivos” en SIMCE si bien generan una ganancia para sus estudiantes en el ciclo común (entre SIMCE de 8º y de 2º Medio), pero parte de ellos se diluyen en el ciclo diferenciado (3º-4º medio)

Abstract:
I’m interested in the way we stage our identity through objects. How objects relate to identity and body. I have been looking into how the self conception and creation of identity is affected by living in an individualistic, capitalistic and mass medial time. I carry a question, how much of the self is really just a replica of a replica? In this essay I discuss how the consumption of different kinds of media gives us knowledge and experiences of the world that is secondary. I explain how I experience that social media creates a thinking where I’m looking at my self from the outside and that this thinking makes my experiences indirect. I look at the individualization of the society and how I think the individualization affects the way we create collective and individual identities. Furthermore, I discuss how object become signifiers of identity and how we, within the consumer society, consume signs rather than objects. I look at the home, as a keeper of identity and memory, I also resemble the home with an organism where the human body only become a part of a bigger body. I discuss how body and object are intertwined both mentally and physically. Jewellery art and corpus is located between art and utility objects, my field gives me the opportunity to discuss the symbolism of the objects we surround ourselves with. In this essay I give a summary of my thinking around materials, methods and sources of inspiration in my work with Replika på replika. I go through my thinking around padded textile objects, the colour pink, the use of aluminium and how I work with reflection and figurative painting. I connect my work with my thoughts on caricatures, cartoons, pop musicians ways of working with characters and to art within different fields.

Abstract:
This bachelor thesis brings up a discussion about museums availability and access to thearchaeological display objects towards blind and visually impaired visitors. The study phasewill take start in analyzing four museums in south Sweden, all which have exhibitions aboutthe prehistory.Visually impaired and blind visitors don’t have a lot to go on at the current exhibitions aboutprehistory. This is because of the lack of access and availability when it comes to their specialneed. To raise awareness to this problem I took out a survey for the museums to answer. I alsovisited two of the exhibitions to make my own opinion of the museums public areas; such asthe entrance, hallway and the exhibition area. Things I looked out for were Braille, audioguides and objects to touch.The sense to touch is of most importance for visually impaired and blind to create an image ofan object. Because of this I discuss the ability for an exhibition where most of the objects areexposed to all visitors to be touched. An exposure of archaeological object to benefit needsfor visually impaired is an important discussion towards the management of thearchaeological display objects, which leads the study towards replicas and experimentalarchaeology.The conclusion was that it is quite possible to design and customize an archaeologicalexhibition for the visually impaired by factors like; reconstructed objects, route marker fororientation, Braille and audio guides with well rendered image descriptions.

Abstract:
In order to fulfill the increasing energy demand, several improvements can be done in already existing means of producing energy. Based on the idea of light harvesting, several main ideas of optimizing natural leaves (or even creating from a master), such as morphology, super-hydrophobity and waterproofing, among others, have been analyzed. Experimentally, it has been shown that by means of applying natural coatings of wax (from bilberry and lingonberry) onto the surface of silicon and PDMS the reflectance varies in the visible spectrum. In the case of silicon the reflectance decreased on average 17.5% in the case of the bilberry wax and 18.4% for lingonberry wax. For PDMS, the curves were more complex and implied an increase of reflectance of 1.3% for bilberry and 2.4% for lingonberry. Finally, a Scanning Electron Microscope imaging experiment was carried out, revealing that for a film coating of wax bigger specks formed (circa 0.1 mm), thus leading to the conclusion that a spin coating is the best option to achieve optimal properties, since the smaller specks would not override other applied coating and natural properties.

Abstract:
Audiovisual concatenative synthesis is an analysis-driven granular technique using a corpus of multimedia data to sequence audio and video streams on a microtemporal level. This text outlines my development of this technique as a tool for multimedia composition, using my work, Replica, as a case study. The paper illustrates how the concepts of granular structure, gesture capture, and replication are integral not only to the software but to the architecture of the composition. In doing so, machine learning approaches to music and visual art are reviewed and related to my personal compositional practice. Additionally, I attempt to show how audiovisual concatenative synthesis provides a composer with strategies for shaping one's sense of time through disorienting audiovisual cues and tightly organized counterpoint between sound and image, stage and screen, and the real and virtual.

Abstract:
This thesis addresses the problem of replica management in a distributed object-oriented database system. It presents a protocol to ensure data consistency across the different nodes of the system. This protocol relies on recent advances in group communication techniques, and on the use of atomic broadcast as a building block to help serialize conflicting transactions. The protocol was implemented in the context of the GlobData project. GlobData was an European IST project designed and implemented a data management middleware tool, named COPLA. The tool offers the abstraction of a global object database repository, supporting transactional access to geographically distributed persistent objects independent of their location. COPLA supports the replication of data according to different consistency criteria. Each consistency criteria is implemented by one or more consistency protocols, that offer different trade-offs between performance and fault-tolerance. A general description of the algorithm is given, followed by a thorough description of its implementation within the COPLA tool. This implementation is then evaluated against other COPLA consistency protocols

Abstract:
In today’s distributed applications, replica placement is essential since moving the data in the vicinity of an application will provide many benefits. The increasing requirements of data for scientific applications and collaborative access to these data make data placement even more important. Until now, replication is one of the main mechanisms used in distributed data whereby identical copies of data are generated and stored at various distributed sites to improve data access performance and data availability. Most work considers file’s popularity as one of the important parameters taken into consideration when designing replica placement strategies. However, this thesis argues that a combination of popularity and affinity files are the most important parameters which can be used in decision making whilst improving data access performance and data availability in distributed environments. A replica placement mechanism called Affinity Replica Placement Mechanism (ARPM) is proposed focusing on popular files and affinity files. The idea of ARPM is to improve data availability and accessibility in peer-to-peer (P2P) replica placement strategy. A P2P simulator, PeerSim, was used to evaluate the performance of this dynamic replica placement strategy. The simulation results demonstrated the effectiveness of ARPM hence provided a proof that ARPM has contributed towards a new dimension of replica placement strategy that incorporates the affinity and popularity of files replicas in P2P systems.

Full text
Abstract:
<p>High availability in database systems is achieved using data replication and online repair. On a system containing 2 replicas of each fragment, the loss of a fragment replica due to a node crash makes the system more vulnerable. In such a situation, only one replica of the fragments contained in the crashed node will be available until a new replica is generated. In this study we have investigated different methods of regenerating a new fragment replica that is up to date with the transactions that have happened during the process of regenerating it. The objective is to determine which method performs the best in terms of completion time at each of the nodes involved, in different conditions. We have investigated three different methods for sending the data from the node containing the primary fragment replica to the node being repaired, and one method for catching-up with the transactions executed at the node containing the primary fragment replica during the repair process. These methods assume that the access method used by the DB system is B-trees. The methods differ by the volume of data sent over the network, and by the work (and time) needed to prepare the data prior to sending. They consist respectively in sending the entire B-tree, sending the leaves of the B-tree only, and sending the data only; the latter has two alternatives on the node being repaired, depending on whether the data is being inserted into a new B-tree, or whether the B-tree is being regenerated from the leaf-level and up. This study shows that the choice of recovery method should be made considering the network configuration that will be used. For common network configurations like 100Mbits or lower, it is interesting to use methods that minimize the volume of data transfered. For higher network bandwidth, it is more important to minimize the amount of work done at the nodes.</p>

Abstract:
Dissertação para obtenção do Grau de Mestre em Engenharia Informática<br>Replication is a key technique for improving performance, availability and faulttolerance of systems. Replicated systems exist in different settings – from large georeplicated cloud systems, to replicated databases running in multi-core machines. One feature that it is often important is a mechanism to verify that replica contents continue in-sync, despite any problem that may occur – e.g. silent bugs that corrupt service state. Traditional techniques for summarizing service state require that the internal service state is exactly the same after executing the same set of operation. However, for many applications this does not occur, especially if operations are allowed to execute in different orders or if different implementations are used in different replicas. In this work we propose a new approach for summarizing and recovering the state of a replicated service. Our approach is based on a novel data structure, Scalable Counting Bloom Filter. This data structure combines the ideas in Counting Bloom Filters and Scalable Bloom Filters to create a Bloom Filter variant that allow both delete operation and the size of the structure to grow, thus adapting to size of any service state. We propose an approach to use this data structure to summarize the state of a replicated service, while allowing concurrent operations to execute. We further propose a strategy to recover replicas in a replicated system and describe how to implement our proposed solution in two in-memory databases: H2 and HSQL. The results of evaluation show that our approach can compute the same summary when executing the same set of operation in both databases, thus allowing our solution to be used in diverse replication scenarios. Results also show that additional work on performance optimization is necessary to make our solution practical.

Abstract:
Communication by voice is foundational in our society and many rely on their voices for their occupations. Voice disorders affect a significant number of individuals each year, and diagnosis and treatment improvements are therefore sought via advancements in voice research. Contained in this thesis is a description of work intended to contribute to vocal fold research by using synthetic, self-oscillating vocal fold replicas to study the impact of replica vibration on perfusion fluid flow through the replica. Methods for manufacturing vocal fold replicas containing imbedded channels allowing for fluid perfusion are discussed. Experimental procedures developed for delivering perfusion fluid to the imbedded channel at a constant pressure during replica vibration are described. Methods for measuring perfusion parameters of perfusion fluid pressure, imbedded channel diameter, flow rate, and vibration parameters (subglottal pressure, frequency, amplitude, channel length, and glottal width) are detailed. Experiments performed using both stationary and vibrating vocal fold replicas are presented. Correlations between perfusion pressure and channel diameter are discussed. Vibration parameters were correlated to perfusion flow parameters and it is shown that perfusion flow rate through the channels decreased significantly with model vibration. Potential mechanisms for changes in perfusion flow resistance with vibration are discussed and analyzed. Output of a theoretical model, developed to incorporate some of the possible flow resistance mechanisms, was compared to vibrating replica experimental data.

Full text
Abstract:
Tombusviruses are single, positive strand RNA viruses of plants, often associated with parasitic defective interfering (DI) RNAs. Two viral- coded gene products, namely p33 and p92, are required for tombusvirus replication. The overlapping domains of p33 and p92 contain an arginine/proline-rich (RPR) RNA binding motif. In this study, the role of RPR motif and viral RNA in tombusvirus replication and recombination, as well as involvement of viral RNA in tombusvirus replicase assembly was examined. Using site-directed mutagenesis I generated a series of RPR mutants of Cucumber necrosis tombusvirus (CNV). Analysis of RPR mutants defined that wild type RPR motif, especially two of the four arginines, were required for efficient RNA binding in vitro, for replication of tombusviruses, their associated DI RNAs, subgenomic (sg)RNA synthesis and DI RNA recombination in vivo. Experiments using a two-component tombusvirus replication system showed that RPR motif is critical for functions of both p33 and p92 in replication, but its role in these proteins might not be identical. Recombination studies using a novel tombusvirus three-component system revealed that mutations in RPR motif of p33 replicase protein resulted in an altered viral RNA recombination rate. Identified DI RNA recombinants were mostly imprecise, with recombination sites clustered around a replication enchancer and an additional putative cis-acting element that might facilitate the template switching events by the tombusvirus replicase. To study the role of RNA during the assembly of functional tombusvirus replicase, recombinant CNV replicase that showed similar properties to plant-derived CNV replicase was purified from Saccharomyces cerevisiae. When in addition to p33 and p92 proteins DI RNA was co-expressed in yeast cells, the isolated replicase activity was increased ~40 fold. Further studies defined RNA motifs within two short DI RNA regions that enhanced active CNV replicase formation. In summary, this study showed that the conserved RNA binding motif of the tombusvirus replicase proteins and viral RNA are involved in replicase assembly, viral RNA replication, subgenomic RNA synthesis and RNA recombination. This data shed new light on the complex roles of the viral elements in replication, and will help future studies aimed at interfering with viral infections.

Abstract:
Microfluidics provides an opportunity to create low cost devices that can potentially contain many elements of a diagnostics lab on a single chip. While the cost of the finished product may be low, a common method of fabricating microfluidic devices such as soft lithography can be expensive to prototype due to the use of photolithography equipment meant for the semiconductor industry. In addition, the majority of microfluidic research has been done using rectangular channels but in some cases the ability to make circular cross-section channel microfluidic devices would be very useful. For areas such as modelling cardiovascular flows, investigating micro flow cytometry and inertial particle focusing, the ability to create circular channels could provide improvement over the use of rectangular channels. To address these issues, an ultra low cost method of making silicon molds patterned with SU-8 has been developed as well as a method to create circular microfluidic channels via hot embossing and double casting techniques in both thermoplastic materials and PDMS. This hot embossing based method to create round channels allows for the rapid creation of straight and curving round channels in PMMA and other plastics as well as a method to create PDMS round channels using soft lithography.<br>Applied Science, Faculty of<br>Graduate

Abstract:
Avec le développement de l'Internet, l'informatique s'est basée essentiellement sur les communications entre serveurs, postes utilisateurs, réseaux et data centers. Au début des années 2000, les deux tendances à savoir la mise à disposition d'applications et la virtualisation de l'infrastructure ont vu le jour. La convergence de ces deux tendances a donné naissance à un concept fédérateur qu'est le Cloud Computing (informatique en nuage). Le stockage des données apparaît alors comme un élément central de la problématique liée à la mise dans le nuage des processus et des ressources. Qu'il s'agisse d'une simple externalisation du stockage à des fins de sauvegarde, de l'utilisation de services logiciels hébergés ou de la virtualisation chez un fournisseur tiers de l'infrastructure informatique de l'entreprise, la sécurité des données est cruciale. Cette sécurité se décline selon trois axes : la disponibilité, l'intégrité et la confidentialité des données. Le contexte de nos travaux concerne la virtualisation du stockage dédiée à l'informatique en nuage (Cloud Computing). Ces travaux se font dans le cadre du projet SVC (Secured Virtual Cloud) financé par le Fond National pour la Société Numérique " Investissement d'avenir ". Ils ont conduit au développement d'un intergiciel de virtualisation du stockage, nommé CloViS (Cloud Virtualized Storage), qui entre dans une phase de valorisation portée par la SATT Toulouse-Tech-Transfer. CloViS est un intergiciel de gestion de données développé au sein du laboratoire IRIT, qui permet la virtualisation de ressources de stockage hétérogènes et distribuées, accessibles d'une manière uniforme et transparente. CloViS possède la particularité de mettre en adéquation les besoins des utilisateurs et les disponibilités du système par le biais de qualités de service définies sur des volumes virtuels. Notre contribution à ce domaine concerne les techniques de distribution des données afin d'améliorer leur disponibilité et la fiabilité des opérations d'entrées/sorties dans CloViS. En effet, face à l'explosion du volume des données, l'utilisation de la réplication ne peut constituer une solution pérenne. L'utilisation de codes correcteurs ou de schémas de seuil apparaît alors comme une alternative valable pour maîtriser les volumes de stockage. Néanmoins aucun protocole de maintien de la cohérence des données n'est, à ce jour, adapté à ces nouvelles méthodes de distribution. Nous proposons pour cela des protocoles de cohérence des données adaptés à ces différentes techniques de distribution des données. Nous analysons ensuite ces protocoles pour mettre en exergue leurs avantages et inconvénients respectifs. En effet, le choix d'une technique de distribution de données et d'un protocole de cohérence des données associé se base sur des critères de performance notamment la disponibilité en écriture et lecture, l'utilisation des ressources système (comme l'espace de stockage utilisé) ou le nombre moyen de messages échangés durant les opérations de lecture et écriture<br>With the development of Internet, Information Technology was essentially based on communications between servers, user stations, networks and data centers. Both trends "making application available" and "infrastructure virtualization" have emerged in the early 2000s. The convergence of these two trends has resulted in a federator concept, which is the Cloud Computing. Data storage appears as a central component of the problematic associated with the move of processes and resources in the cloud. Whether it is a simple storage externalization for backup purposes, use of hosted software services or virtualization in a third-party provider of the company computing infrastructure, data security is crucial. This security declines according to three axes: data availability, integrity and confidentiality. The context of our work concerns the storage virtualization dedicated to Cloud Computing. This work is carried out under the aegis of SVC (Secured Virtual Cloud) project, financed by the National Found for Digital Society "Investment for the future". This led to the development of a storage virtualization middleware, named CloViS (Cloud Virtualized Storage), which is entering a valorization phase driven by SATT Toulouse-Tech-Transfer. CloViS is a data management middleware developped within the IRIT laboratory. It allows virtualizing of distributed and heterogeneous storage resources, with uniform and seamless access. CloViS aligns user needs and system availabilities through qualities of service defined on virtual volumes. Our contribution in this field concerns data distribution techniques to improve their availability and the reliability of I/O operations in CloViS. Indeed, faced with the explosion in the amount of data, the use of replication can not be a permanent solution. The use of "Erasure Resilient Code" or "Threshold Schemes" appears as a valid alternative to control storage volumes. However, no data consistency protocol is, to date, adapted to these new data distribution methods. For this reason, we propose to adapt these different data distribution techniques. We then analyse these new protocols, highlighting their respective advantages and disadvantages. Indeed, the choice of a data distribution technique and the associated data consistency protocol is based on performance criteria, especially the availability and the number of messages exchanged during the read and write operations or the use of system resources (such as storage space used)

Abstract:
The stability of rock masses is influenced by the occurrence of rock joints. Therefore, the shear strength of rock joints must be considered in dimensioning of underground constructions. One way to predict the shear strength is through usage of failure criteria, which are validated from results of direct shear tests under controlled laboratory conditions. Consequently, the quality of the results from the tests are crucial to the accuracy with which the criteria will be able to predict the shear strength. Since rock joints are unique by nature usage of replicas (man-made copies of rock joints) is of importance in parameter studies. The overall objective of this work is to facilitate the development of improved criteria for predictions of the shear strength of rock joints. To support this objective, two sources of uncertainty have been investigated, namely the geometry of replicas and the influence of the normal stiffness of test systems. Two quality assurance parameters for evaluation of geometrical differences between replicas and rock joints based on scanning data have been derived. The first parameter describes the morphological deviations. The second parameter describes the deviations in orientation with respect to the shear plane. The effective normal stiffness approach, which compensates for the influence of the normal stiffness of the test system indirect shear testing, has been developed, validated, and applied. With help of the quality assurance parameters it is demonstrated that it is possible to reproduce replicas within narrow tolerances. Application of the effective normal stiffness approach basically eliminates the normal load error. In all, the results support generation of improved quality of test data and consequently, the development of shear strength criteria with improved accuracy will also be facilitated.<br>Bergmassors stabilitet påverkas av bergssprickor. Bergssprickors skjuvhållfasthet behöver därför beaktas vid fastställandet av vilka laster berganläggningar skall dimensioneras mot. Skjuvhållfastheten predikteras bland annat med hjälp av brottkriterier, vilka valideras med hjälp av resultaten från skjuvtester i kontrollerad laboratoriemiljö. Kvaliteten på resultaten från testerna är därför av avgörande betydelse för med vilken noggrannhet kriterierna kommer att kunna prediktera skjuvhållfastheten. Det övergripande målet med detta arbete är att underlätta utvecklingen av förbättrade kriterier för prediktioner av bergssprickors skjuvhållfasthet. Som ett bidrag till att uppnå detta mål har två osäkerhetsfaktorer undersökts, nämligen geometrin av replikor (kopior) av bergssprickor och inverkan av testsystems normalstyvhet. Två kvalitetssäkringsparametrar för utvärdering av de geometriska skillnaderna mellan replikor och bergprov baserade på skanningdata har tagits fram. Den första parametern beskriver de morfologiska avvikelserna. Den andra parametern beskriver avvikelserna i orientering med avseende på skjuvplanet. Ett tillvägagångssätt med en effektiv systemnormalstyvhet, vilken kompenserar för inverkan av testsystemets normalstyvhet, har utvecklats, validerats och tillämpats. Med hjälp av kvalitetssäkringsparametrarna påvisas att det ar möjligt att reproducera replikor inom snäva toleranser. Genom tillämpning av tillvägagångssättet med en effektiv normalstyvhet kan felet i normallast i princip elimineras. Sammantaget stödjer resultaten framtagning av testdata med förbättrad kvalitet och därigenom underlättas även utvecklingen av skjuvhållfasthetskriterier med förbättrad noggrannhet.<br><p>QC 210518</p>

Abstract:
L'architecture géo-distribuée de fog computing fournit aux utilisateurs des ressources accessibles avec une faible latence. Cependant, exploiter pleinement cette architecture nécessite une distribution similaire de l'application par l'utilisation de techniques de réplication. Par conséquent, la gestion de ces répliques doit intégrer des algorithmes prenant en compte la proximité aux différents niveaux de gestion des ressources du système. Dans cette thèse, nous avons abordé ce problème à travers trois contributions. Premièrement, nous avons conçu un système de routage des requêtes entre les utilisateurs et les ressource prenant en compte la proximité. Deuxièmement, nous avons proposé des algorithmes dynamiques pour le placement des répliques prenant en compte les derniers percentiles de la latence. Enfin, nous avons développé un système de mise à l’échelle automatique qui ajustent le nombre des répliques de l'application en fonction de la charge subie par les applications fog computing<br>Geo-distributed fog computing architectures provide users with resources reachable within low latency. However, fully exploiting the fog architecture requires a similar distribution of the application by the means of replication.

In this thesis, we addressed this problem over three contributions. First, we designed a proximity-aware user-to-replica routing mechanism. Second, we proposed dynamic tail-latency-aware replica placement algorithms. Finally, we developed autoscaling algorithms to dynamically scale the application resources according to the non-stationary workload experienced by fog platforms

Doutoramento em Engenharia Civil<br>O principal objectivo deste trabalho foi sistematizar características físico- químicas dos azulejos para conservação e restauro de fachadas azulejares da cidade de Ovar, pertencentes à fase produtiva da semi-industrialização e industrialização dos finais do século XIX inico do século XX, de forma a produzir réplicas técnicas para recolocação nos locais de fachada com lacunas de azulejo. Além de se ter criado uma base de dados sobre estes materiais, formularam-se réplicas para os corpos cerâmicos calcários e pó de pedra, sugerindo matérias-primas e grau de moagem para a sua formulação, pressão de prensagem, ciclo e temperaturas máximas de cozedura conferindo-lhes características técnicas para que estas possam ser aplicadas lado a lado com os azulejos seculares, sem que perturbem a unicidade técnica da fachada. Investigaram-se duas das patologias mais recorrentes que afectam o vidrado: destacamento por cristalização de sais e fendilhamento. A primeira afecta a perda da parte pictórica do azulejo, atirando-o para uma remoção compulsiva da fachada aquando da sua intervenção para conservação restauro. A segunda permite-nos compreender possíveis compromissos técnicos feitos no passado.<br>The main objective of this work was to systematize physic-chemical characteristics of tiles removed for conservation and restoration of façades in the city of Ovar, belonging to the productive stage of semi industrialisation and industrialisation in late 19th century beginning of 20th century, in order to produce technical replicas to be used in façades gaps. Besides creating a database on these materials with an inexistent extension in Portugal, it was also achieved the lab production of replicas for ceramic bodies of calcitic tiles and pó de pedra, suggesting raw materials and its particle size, pressing pressure, maximum temperatures and firing cycle, assuring technical characteristics so that they can be applied alongside the secular tiles without disturbing the technical harmony behaviour of the facade. Two of the most recurrent pathology affecting the glaze were investigated: glaze detachment promoted by salts crystallization and crazing. The first affects the loss of the tile waterproof decoration, throwing it to a compulsory removal of the facade at its intervention for restore and conservation. The second allows us to understand possible technical commitments made in the past.

Abstract:
REPLICA is a family of novel scalable chip multiprocessors with configurable emulated shared memory architecture, whose computation model is based on the PRAM (Parallel Random Access Machine) model. The purpose of this thesis is to, by benchmarking different types of computation problems on REPLICA, similar parallel architectures (SB-PRAM and XMT) and more diverse ones (Xeon X5660 and Tesla M2050), evaluate how REPLICA is positioned among other existing architectures, both in performance and programming effort. But it should also examine if REPLICA is more suited for any special kinds of computational problems. By using some of the well known Berkeley dwarfs, and input from unbiased sources, such as The University of Florida Sparse Matrix Collection and Rodinia benchmark suite, we have made sure that the benchmarks measure relevant computation problems. We show that today’s parallel architectures have some performance issues for applications with irregular memory access patterns, which the REPLICA architecture can solve. For example, REPLICA only need to be clocked with a few MHz to match both Xeon X5660 and Tesla M2050 for the irregular memory access benchmark breadth first search. By comparing the efficiency of REPLICA to a CPU (Xeon X5660), we show that it is easier to program REPLICA efficiently than today’s multiprocessors.<br>REPLICA är en grupp av konfigurerbara multiprocessorer som med hjälp utav ett emulerat delat minne realiserar PRAM modellen. Syftet med denna avhandling är att genom benchmarking av olika beräkningsproblem på REPLICA, liknande (SB-PRAM och XMT) och mindre lika (Xeon X5660 och Tesla M2050) parallella arkitekturer, utvärdera hur REPLICA står sig mot andra befintliga arkitekturer. Både prestandamässigt och hur enkel arkitekturen är att programmera effektiv, men även försöka ta reda på om REPLICA är speciellt lämpad för några särskilda typer av beräkningsproblem. Genom att använda välkända Berkeley dwarfs applikationer och opartisk indata från bland annat The University of Florida Sparse Matrix Collection och Rodinia benchmark suite, säkerställer vi att det är relevanta beräkningsproblem som utförs och mäts. Vi visar att dagens parallella arkitekturer har problem med prestandan för applikationer med oregelbundna minnesaccessmönster, vilken REPLICA arkitekturen kan vara en lösning på. Till exempel, så behöver REPLICA endast vara klockad med några få MHz för att matcha både Xeon X5660 och Tesla M2050 för algoritmen breadth first search, vilken lider av just oregelbunden minnesåtkomst. Genom att jämföra effektiviteten för REPLICA gentemot en CPU (Xeon X5660), visar vi att det är lättare att programmera REPLICA effektivt än dagens multiprocessorer.

Abstract:
This is a problem of sampling. The number of classical states of an N-body system grows with O( 3 ^ N ). To sample this space, advanced techniques are required. Replica Exchange (RE), also known as parallel tempering, is an example that uses parallelization, and Hamiltonian Replica Exchange is a subset of RE that scales the energy of the replicas. The number of simulations required grows at O( N^(1/2) ), where N is number of atoms in the system. Replica Exchange with Dynamical Scaling (REDS) attempts to address this problem to decrease computational cost. It has been shown to increase efficiency 10-fold. We implemented REDS in GROMACS 2018. (Abraham 2015) All changes to the source code were written in the form of parallel methods. Scripts were written in Python and Perl to automate the experiment entirely. An exchange connects a region of high energy space, far above the surface of the landscape, to low energy space, which approaches the surface of the landscape, which represents the natural conformational progression of the molecule. Using REDS we were able to achieve exchanges at temperatures spaced too far apart to exchange using normal RE. Ergo, the flexibility of dynamical scaling allowed regions of phase space that would have gone unsampled to be mapped, addressing our initial problem of sampling.

Abstract:
Diatoms possess characteristics such as abundance, diversity, and high reproductivity, which make their nano-structured frustules (diatom frustules) attractive for a wide range of applications. To overcome the limitation of their silica based frustule composition, diatom frustules have been converted into a variety of materials including silicon, silicon carbide, silver, gold, palladium and carbon in the present study. The compositions and the extent of shape preservation of the replicas are examined and evaluated with different characterization methods such as X-ray diffraction, SEM, TEM and FTIR analyses. These replicas still retained the complex 3D structures and nano-scaled features of the starting diatom frustules. Some properties and possible applications of converted materials are explored and the kinetics and thermodynamics related to the successful replications (conversions) are also studied and discussed.

Abstract:
Characterization of small precipitates is important for development of new alloys. One inherent  difficulty  in  characterisation  of  small  precipitates  with  electron microscopy techniques  while  the  particles  are  embedded  in  the  matrix,  is  that the surrounding bulk material will contribute to the analysed signal- limiting, for example, the quantification of the composition of particles.  In order to avoid the matrix contribution, the extraction replica technique was developed in the 1950's. Extraction replicas are made by extracting only the particles from a material onto a thin film for further analysis by scanning or transmission electron microscopy. Different types of particles can be examined by this technique, including various carbides, nitrides, oxides and borides, as well as many intermetallic phases.  In this work, direct replication techniques were compared to two-stage replication for low-alloyed steel, concluding that both are suitable for qualitative analysis, but direct replication is preferred for quantitative analysis.  Successful replication of the zirconium-based Zirlo and the stainless steel 254 SMO was performed, where the precipitated phases were isolated and the composition quantified.   Particle extraction was successful also for the zirconium-based Zircaloy-2 and two types of  aluminium  alloys,  but  no  quantification of  composition  could  be  made  due to different problems associated with etching of each alloy, showing that properchoice of etchant is crucial for the quality of the replicas.<br>Karaktärisering av små utskiljningar är viktigt för utveckling av nya legeringar. En svårighet  vid  karaktärisering  av  små  utskiljningar  med elektronmikroskopi när partiklarna  sitter  kvar  i  matrisen  är  att  matrisen kommer  ge  ett  bidrag till den analyserade signalen,  därför är t.ex.   möjligheterna för kvantifiering av sammansättning begränsade. För att undvika bidraget från matrisen utvecklades extraktionsrepliker  på  1950-talet.  Extraktionsrepliker  tillverkas  genom  att extrahera partiklar från ett material till en tunn film som sedan kan analyseras med hjälp av svep- eller transmissionselektronmikroskopi. Olika sorters partiklar kan  undersökas  med hjälp  av  denna  metod.     Dessa  inkluderar  olika  typer av  karbider, nitrider, borider, oxider  och  många  olika  sorters  intermetalliska partiklar. I  detta arbete  jämfördes direkta  metoder  med  tvåstegsrepliker  på låglegerat  stål. Slutsatsen  blev  att  båda metoderna  lämpar  sig  för  kvalitativ analys av små partiklar, men direkta metoder är att föredra för kvantitativ analys. Lyckade repliker tillverkades även av zirkoniumlegeringen Zirlo och det rostfria stålet  254  SMO,  där  utskiljningarna  kunde isoleras  och sammansättningen kvantifieras.   Extraktion  av  partiklar  var  lyckad  även  för zirkoniumlegeringen Zircaloy-2  samt  två  typer  av  aluminiumlegeringar, men ingen  kvantifiering  av sammansättningen  kunde  göras  på  grund  av  olika problem  relaterade  till  den valda etsmetoden för varje legering, vilket visar att valet av etsmedel ar avgörande för kvaliteten av replikerna.

Abstract:
In this thesis, we apply methods from replica theory to deal with two contemporary problems in the study of complex systems. In Part I, we discuss the behavior of the rare fluctuations of the observable of choice in most models of spin glasses: the free energy. Due to the quenched disorder, this and other thermodynamic quantities are self-averaging random variables, whose probability distribution can be evaluated within replica theory. In particular, the probability of the free energy fluctuations above its typical value shows an anomalous scaling with the number of degrees of freedom, at variance with the ordinary exponential suppression for fluctuations below. We explain how the introduction of a small magnetic field can remove this anomalous behavior. In Part II, we apply the replica formalism to the problem of linear classification of objects with a geometrical structure, in the context of machine learning. In particular, using combinatorial techniques we evaluate the number of dichotomies (binary classifications) of a set of structured inputs achievable by a linear classifier, as a function of the number of inputs to classify. We prove that this number shows an additional critical point beyond the usual storage capacity for isolated points, at which the number of admissible dichotomies becomes zero in the thermodynamic limit; the associated phase transition present a certain degree of replica symmetry breaking. This behavior is due to a trade-off between the increasing number of points to classify, and the increasing volume excluded by their geometrical structure. This approach goes in the direction of finding bounds on the generalization error of certain simple neural network architectures, more stringent for structured data than the ones known from Statistical Learning Theory.

The analysis is conducted from the perspective of the manufacturer's North American distribution center, and how flexibility can be employed to meet customer demands. NFL replica jerseys can be stocked either completed with player name and number, called "dressed" or as "blank" jerseys that can be customized at the distribution center. Player demand can change drastically from year to year. The result is that common practice is to minimize inventory at year-end, and treat each season as a single period. The approach taken utilizes the newsvendor model to determine the optimal stocking levels of replica jerseys given an expected demand forecast. Two modeling approaches were compared, the traditional newsvendor problem and a newsvendor model with risk pooling. The traditional newsvendor problem separated selected players to order as dressed jerseys and remaining demand to order as "blank" jerseys. The second approach, the newsvendor with risk pooling, provides a more flexible inventory plan that satisfies selected player demand using a combination of dressed and blank jerseys. The newsvendor model with risk pooling resulted in the higher expected profits then the traditional newsvendor model, and comparable service levels, but at much lower inventory levels.<br>by John C.W.

Abstract:
Mesoporous nanostructured materials are useful for a widespread field of applications, such as gas storage; selective molecular adsorption; confined chemical reactions and catalysis. In this work, periodic mesoporous silica and organosilica materials, thanks to their high surface area, narrow pore size distribution and high regular structure, have been exploited to obtain nanostructured porous materials with different chemical nature, such as polymer or carbon. Periodic mesoporous silica objects with defined micrometric shape have been obtained by template synthesis in aqueous medium. A change in synthesis condition of temperature, time and acidity leads to the generation of different shapes such as gyroids, spheres and hollow tubes. Mesoporous silica particles have been exploited for confined polymerization of different monomers (styrene, methylmethacrylate and acrylonitrile) to obtain morphological polymeric nanocomposites. The nanocomposite with polyacrylonitrile has been then heated at high temperature in non-oxidative atmosphere to induce polymer carbonization until the formation of a graphitic-like carbon structure. The silica matrix has been then removed by chemical etching to obtain nanostructured porous materials in polymer and graphitic-like carbon with high surface area and the same micrometric morphology of starting silica matrix (shape replica effect). Afterwards, a periodic mesoporous organosilica system, with phenylene groups directly linked in the wall structure and organized on the molecular scale, has been synthesised, exploited as selective gas adsorption system and heated in non-oxidative atmosphere to obtain a new mesoporous carbon material with high surface area, very regular mesoporous structure and graphitic-like pore walls. Characterization of these materials has been conduced with X-ray diffraction, calorimetric techniques (DSC and TGA), adsorption of gases and vapours and advanced mono- and bi-dimensional NMR experiments to investigate the interaction between the organic and the inorganic moieties. Thermal evolutions of polyacrylonitrile and phenylene-organosilica have been studied with spectroscopic techniques of ATR and Raman, while the shape replica effect and the high regular pore structure have been directly seen with SEM and TEM microscopies.

Model computations show that the strength of the replicas is determined by the Coulomb interactions between electrons and holes, which modify the localization of the envelope wave functions and the net charge distribution.<br><p>Original Publication: Daniel Dufåker, Fredrik Karlsson, V Dimastrodonato, L O Mereni, Bo Sernelius, Per-Olof Holtz and E Pelucchi, Phonon replicas of charged and neutral exciton complexes in single quantum dots, 2010, PHYSICAL REVIEW B, (82), 20, 205421. http://dx.doi.org/10.1103/PhysRevB.82.205421 Copyright: American Physical Society http://www.aps.org/</p>

Abstract:
PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO<br>Seguindo uma tendência mundial, o consumo de produtos falsificados tem se ampliado consideravelmente no Brasil, com relevantes consequências econômicas e sociais. Apesar de sua característica de exclusividade, os produtos de marcas de luxo não são imunes a esse processo. Réplicas de artigos como bolsas e relógios de marcas historicamente inacessíveis para muitos, por exemplo, podem ser adquiridos com facilidade no país. A desmistificação do luxo é, em grande parte, resultado da evolução do seu significado: partindo de uma lógica artesanal para uma visão financeira e industrial, o luxo caminhou pela modernidade e pós-modernidade - era do consumo movido pelo simbolismo e pela união do real e do imaginário, até, finalmente, democratizar-se através do novo luxo, abrindo as portas para a falsificação. Nesse contexto, o presente estudo buscou responder à seguinte pergunta: Quais valores podem ser considerados responsáveis pela decisão de compra de bolsas falsificadas da marca Louis Vuitton? Para tanto, foi realizada uma pesquisa exploratória, em que 15 mulheres que compraram bolsas Louis Vuitton falsificadas foram submetidas a entrevistas em profundidade analisadas pela técnica Laddering. O resultado do estudo sugere que, para além dos atributos do produto, avaliado como de elevada beleza, a bolsa faz com que as mulheres sintam-se possuidoras de imponência e status. Ao comprarem a bolsa Louis Vuitton, mesmo falsificada, as consumidoras buscam o pertencimento e procuram elevar a autoestima, valor que atua como principal motivador da decisão de compra.<br>Following a global trend, the consumption of counterfeit goods is substantially spreading in Brazil, with significant economic and social consequences. Despite its uniqueness, luxury brand products are not immune to this process. Replicas of items such as handbags and watches produced by brands that are historically inaccessible for many, for example, can be easily purchased in the country. The demystification of luxury is the result of the evolution of its meaning: starting from craft logic onto a financial and industrial vision, luxury strode through modernity and post-modernity – the consumption era driven by symbolism and the merging of real and imaginary until finally democratize itself through what is known as new luxury, making counterfeit possible. In this context, the present study intends to comply with the following question: Which values could be held responsible for the buying decision of counterfeit Louis Vuitton handbags? To this end, we conducted an exploratory study in which 15 female subjects who bought counterfeit Louis Vuitton handbags were subjected to in-depth interviews analyzed using Laddering. The result of the study suggests that besides the product attributes, evaluated as extremely beautiful, to own a handbag made women feel imponent and with a certain status. When acquiring a Louis Vuitton hanbag, even though counterfeit, female consumers crave for belonging and raising their self-esteem, a value that is the primary motivation of the purchase decision.

Abstract:
The generation of nanostructured microscale assemblies with complex, three-dimensional (3-D) morphologies possessing multicomponent inorganic compositions tailored for adhesion is of considerable scientific and technological interest. This dissertation demonstrates that self-assembled 3-D organic templates of biogenic origin can be converted into replicas comprised of numerous other functional nanocrystalline inorganic materials and, further, how such replicas can tailored for adhesion. Nature provides a spectacular variety of biologically-assembled 3-D organic structures with intricate, hierarchical (macro-to-micro-to-nanoscale) morphologies designed for particle adhesion. The conformal coating of such structurally-complex biotemplates with synthetic materials provides a framework for chemical transformation of other, complex synthetic organic templates and the basis to study imparted adhesion properties. Three specific research thrusts are detailed in this document. First, freestanding magnetite (Fe3O4) replicas of bio-organic templates are synthesized via a layer-by-layer (LbL) wet chemical deposition process and subsequent morphology-preserving thermal treatments to allow for structures with tailorable long-range magnetic adhesion. Second, freestanding spinel ferrite replicas of bio-organic templates are synthesized (via LbL coating and thermal treatment) for grain size controlled long-range magnetic adhesion and short range van der Waals adhesion. The final research thrust focuses on the use of a low temperature (≤ 250°C) wet-chemical based process to convert bioorganic templates into magnetically-coated structures retaining both the size and morphology of the template. The rate-limiting kinetic mechanism(s) of the partial reduction of the inorganic coatings have been examined via quartz crystal microbalance analysis. The effects of the coating micro/nanostructure on magnetic behavior and on surface adhesion, have been investigated.
