Zheng, Wenbo, and Hongxi Zhong. "Reconfigurable Machine Tools Design Methodology." Thesis, KTH, Industriell produktion, 2012. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-119082.
Full textAbstract:
In today’s industry, the competitive market, the short life time of the products and rapid change in customer demand forms a big trend of appearance of new manufacturing system. Reconfigurable Machine Tool (RMT) is a kind of solution for future machining systems, thus it can not only provide customized solutions to the operation requirements but also is cost-effective. Thethesis aims to create and implement methodology of RMT design for manufacturing industry. The methodology is introduced and extended according to the five principals of modular machine tool design. The methodology will be applied step by step herein so as to make the methodology more clear. First of all is to get the concept or process requirements from the customer. The customer requires three reconfigurable part families for a high speed milling application including tables, spindles, and cutters. In this case, to fulfill customer’s requirements and concept, the dual spindle (Multi-tool) RMT is selected as an example to interpret the RMT design methodology. Secondly, the most important point in methodology of RMT design is to analyze the valuable proposal of the four principles of modular design based on extensive experience. This work turns the four principles, separation, and unification (standardization), connection, and adaptation, to practical design methodology. Based on the classical four principles, the principle of reusability is an addition principal in consider of zero waste concept. In order to perform the RMT design methodology effectively, it is necessary to complement the advantages of the reconfiguration in dual spindle RMT design and the reconfiguration for other part families in according to the RMT design methodology. A final step utilizes computer software to model the configuration in 3 dimensions. And evaluations can be discussed in Degree of Freedom (DOF), stiffness analysis and number of modules.

The aim of this study is to present teacher and student views on, and usage of, digital learning tools in the Swedish upper secondary English language classroom, as well their views on a comparison between digital and traditional learning tools. Digital learning tools have seen an increase in both usage and development, something that began as early as the 1990’s, and has become a more common sight in Swedish upper secondary schools. Previous research conducted about digital learning tools and their application in both the general and the English language classroom is presented and used to both analyze and discuss empirical data; said data has been received through a qualitative methodology comprised of two focus group interviews with students and teachers. The empirical data is categorized according to each research question, with direct and translated quotes from the focus group interviews. The results of the study show that while digital learning tools viewed in a positive light and their usage is appreciated by some students, both groups primarily advocate variety in the English language classroom rather than relying exclusively on just one set of tools to create a learning environment that caters to all students rather than a select few.

Full textAbstract:
The advances in silicon technology, as well as competitive time to market, in the recent decade have forced the design tools and methodologies to progress towards higher levels of abstraction. Raising the level of abstraction shortens the design cycle via elimination of details in design specification. One such new methodology is High Level Synthesis (HLS). HLS tools accept the behavioral design in the abstract level as the input and generate the detailed Register Transfer Level (RTL) code. In this thesis project, the HLS methodology is introduced in the design flow and its advantages are outlined. We then evaluate and compare three HLS tools developed by market leading vendors, namely, C-to-Silicon, CatapultC and Synphonycc. To compare the HLS tools, an HLS input is developed for one of the Ericsson’s designs and the generated RTL is compared with the hand-written RTL based on several performance criteria. Thereof, we discuss the choice of the best tool so as to facilitate adoption of HLS in Ericsson’s design flow. At last, capability of the HLS tools in the synthesis of designs with pure control flow is investigated.

Full textAbstract:
The ability to design is the distinguishing characteristic of an engineer. Recent research has increased our understanding of both the engineering design process and effective means for teaching that process to neophyte design engineers. In that spirit, a design methodology was developed at the Institute for Innovation and Design in Engineering (IIDE), Texas A&M University. At the core of this approach is a design philosophy based on the cognitive skills of Abstraction, Critical Parameter Identification, and Questioning. This philosophy along with the design process is taught in the senior undergraduate design and graduate design courses. The goal of the methodology is not only to teach the design process to novice designers but also to instill in them the design philosophy that would enable them to perform design effectively and innovatively in any area of specialty.
In this dissertation the design philosophy along with its role in the design methodology is explained. The Need Analysis and the Conceptual Design stages of the IIDE methodology are elaborated. The weaknesses in these stages are identified and addressed, by developing and incorporating design methods and techniques that fit the spirit and framework of the IIDE design methodology. The Object Function Method was developed to address certain aspects at the Need Analysis stage. There was need for an effective concept searching method within the Concept Design stage of the IIDE design methodology. This is addressed by the development of new search techniques and methods for effective concept discovery during concept searching. The usage and application of these methods and techniques is explained in detail along with examples.
Additionally, this dissertation contains the results of a study conducted with two groups of senior design students, those who have been through the process and those who have not, to evaluate the effectiveness of applying the IIDE design philosophy and performing the Need Analysis and Conceptual Design stages for the given design challenge. The goal of the study was to investigate the relationship, if any, between the degree to which these aspects of the design methodology were followed and the quality of the resulting design solutions produced.

Previous issue date: 2013-08-23<br>It is well-known that model-driven engineering (MDE) is a software development methodology
that focuses on creating and exploiting (specific) domain models. Domain models
(conceptually) capture all the topics (for instance, entities and their attributes, roles, and
relationships as well as more specific constraints) related to a particular problem. It is
common to use domain-specific languages (DSL) to describe the concrete elements of
such models.
MDE tools can easily build domain-specific languages (DSL), capturing syntactic
as well as static semantic information. However, we still do not have a clear way of
capturing the dynamic semantics of a DSL as well as checking the domain properties prior
to generating the implementation code. Formal methods are a well-known solution for
providing correct software, where we can guarantee the satisfaction of desired properties.
Unfortunately the available formal methods tools focus almost exclusively on semantics
whereas human-machine interaction is "left to the user". Several industries, and in
particular the safety-critical industries, use mathematical representations to deal with
their problem domains. Historically, such mathematical representations have a graphical
appeal. For example, Markov chains and fault-trees are used in safety assessment processes
to guarantee that airplanes, trains, and other safety-critical systems work within
allowed safety margins. In general, due to the difficulty to obtain correct software, such
industries use Commercial Off-The-Shelf (COTS) software or build them specifically
to satisfy their needs with a related testing campaign effort. Such DSLs are difficult
to capture, using just MDE tools for instance, because they have specific semantics to
provide the desired (core) information for the industries that use them.
In this sense, given a DSL (L) composed of a syntax and static semantics (SSL),
and dynamic semantics (DSL) parts, our work proposes a rigorous methodology for
combining the easiness of MDE tools, to capture SSL, with the correctness assured by
formal methods, to capture DSL as well and check its properties. This combination
is specifically handled in the following way, we capture all aspects of L using formal
methods, check the desired properties and adjust if necessary. After that, we automatically
translate part of it in terms of constructs of a MDE tool, from which we can build a
user-friendly (GUI) front-end very easily (automatically). Finally, we link the front-end
code to the automatically synthesized code from the formal dynamic semantics back-end.
Although we require the use of a formal methods tool, the distance from the mathematical
representations used in industry and the formal methods notation is very close.
With this proposed methodology we intend that safety-critical industries create their domain specific software as easy as possible and with the desired static and dynamic
properties formally checked.<br>A Engenharia Dirigida a Modelos ou (MDE—Model-Driven Engineering) é uma metodologia
de desenvolvimento de software que se concentra na criação e manipulação de modelos
específicos de domínio. É comum o uso de linguagens específicas de domínio (DSL) para
descrever os elementos concretos de tais modelos.
Ferramentas de MDE podem facilmente construir linguagens específicas de domínio
(DSL), capturando seus aspectos sintáticos assim como sua semântica estática. No
entanto, ainda não possuem uma forma clara de capturar a semântica dinâmica de uma
DSL, assim como a verificação de propriedades de domínio antes da geração de código
executável. Métodos formais são tidos como uma solução para prover software correto,
onde podemos garantir que desejadas propriedades são satisfeitas.
Infelizmente, as ferramentas de métodos formais disponíveis concentram-se quase que
exclusivamente na semântica enquanto que a interação homem-computador é "deixada
para o usuário". Indústrias em que a segurança é crítica, usam representações matemáticas
para lidar com os seus domínios de problemas. Historicamente, essas representações
matemáticas têm um apelo gráfico. Por exemplo, Cadeias de Markov e Árvores de Falha.
Em geral, devido à dificuldade em obter softwares formalmente verificados, essas
indústrias utilizam sistemas comerciais prontos para uso (Commercial Off-the-shelf -
COTS) ou os constróem especificamente para satisfazerem as suas necessidades com
um esforço considerável em testes. Tais DSLs são difíceis de capturar, usando apenas
ferramentas MDE por exemplo, porque possuem uma semântica particular para prover as
informações específicas desejadas para as indústrias que as utilizam.
Neste sentido, dada uma DSL (L), composta por sintaxe e semântica estática (SSL), e
semântica dinâmica (DSL), este trabalho propõe uma metodologia rigorosa para combinar
a facilidade de ferramentas MDE em capturar SSL, com a corretude assegurada por
métodos formais para capturar DSL e verificar suas propriedades. Esta combinação é
especificamente tratada da seguinte maneira: captura-se todos os aspectos de L utilizando
métodos formais, verificam-se as propriedades desejadas e as ajustam caso necessário.
Em seguida, parte de L é traduzida automaticamente em termos de artefatos para uma
ferramenta MDE, a partir da qual é possível construir uma interface amigável (front-end)
facilmente (automaticamente). Por fim, o código do front-end é integrado com o código
sintetizado automaticamente a partir da semântica dinâmica formal (back-end).

Full textAbstract:
Motivated by the need for an evaluation technique to help decision makers ensure the success of their computer-based decision support tools, this research explores the evaluation of decision aids from a broad organizational and managerial perspective. A review of current research identifies the need for theoretical and practical developments emphasizing: (1) evaluation techniques which can work with partial knowledge about the effect of a decision support tool on management processes, (2) a systematic way to prescribe evaluation techniques for different assessment situations, (3) evaluation techniques which provide a way to transition from one assessment situation to another, and (4) evaluation techniques which recognize that the performance of one decision support tool may depend on other decision aids used by the manager. This study complements existing theoretical research by developing seven conceptual models which identify essential evaluation parameters and their relationships. The first model explores parameters affecting the decision to evaluate. The second and third models examine the role of evaluation in ensuring success. The fourth and fifth models analyze how conclusions about success are made. The sixth model identifies components of an evaluation technique. Finally, the seventh model presents a framework for prescribing evaluation approaches. Using the seven conceptual models and previous research as its theoretical foundation, Evalu-Action, a step-by-step practical technique to ensure the success of computer-based decision support tools is developed. The technique is pilot tested and improved. Recommendations for further work are presented.<br>M.S.

Il processo di progettazione in passato si è concentrato principalmente sulla riduzione dei costi,
aumentando la qualità del prodotto e diminuendo i tempi di produzione, a questo scopo sono stati
sviluppati diversi strumenti per assistere il progettista in questa attività. Al giorno d'oggi gli aspetti
ambientali ricoprono un ruolo fondamentale e rappresentano un fattore importante per il successo nel
mercato dei prodotti, infatti tra i consumatori si sta sviluppando una sensibilità ambientale sempre
crescente. Da queste considerazioni viene alla luce l’esigenza di strumenti per assistere i progettisti nel
considerare sia aspetti ambientali che di costi nel processo di progettazione, negli ultimi anni diversi
strumenti sono stati sviluppati a questo scopo. I sistemi IT sono oggi largamente impiegati nel processo
di progettazione e possono essere raggruppati sotto la definizione di PLM (Product Lifecycle
Management). I sistemi PLM possono essere visti come l'integrazione di diversi strumenti con metodi,
persone e processi attraverso tutte le fasi della vita di un prodotto. Per quanto riguarda la valutazione
dell’impatto ambientale dei prodotti, esistono diversi metodo e strumenti a questo scopo, il metodo
LCA (Life Cycle Assessment) è quello più diffuso e riconosciuto per determinare l'impatto ambientale
di prodotti e servizi. Gli obiettivi di questo lavoro possono essere sintetizzati come la definizione di un
nuovo approccio, di una metodologia e di strumenti per l’analisi dell’impatto ambientale e dei costi di
prodotto nel processo di progettazione. Il lavoro svolto rappresenta un passo verso lo sviluppo di un
approccio innovativo e di uno strumento di EcoDesign, integrando sistemi di gestione del ciclo di vita
con metodologie di calcolo dell’impatto ambientale e di costi. La metodologie e lo strumento sviluppato
consentono al progettista di valutare diverse alternative progettuali durante la prima fase di sviluppo del
prodotto. In questo modo è possibile progettare prodotti “green” prendendo in considerazione sia
l'impatto ambientale che l'aspetto legato ai costi del ciclo di vita del prodotto.<br>The design process in the past was focused mainly on cost-reduction, increasing product quality and
time-reduction, several tools have been developed to assist designer in this activity. Nowadays the
environmental aspects have become widely considered and represent an important and success market
factor, in fact the consumers are developing an increasing environmental sensibility so they are
attracted by “green” products. From this considerations come the needs for tools to assist the
designers to consider both the environmental and the cost aspects into the design process, in recent
years several tools were developed at this scope. IT systems are nowadays widely employed in the
design process, they can be grouped under PLM (Product Lifecycle Management) system. PLM can be
viewed as the integration of several tools as mentioned before, with methods, people and the processes
through all stages of a product’s life. On the other hand there are tools to assess and calculate the
environmental impact of products by different methods. LCA (Life Cycle Assessment) is the most
common and recognized method to determine the environmental burden of products and services. The
research goals could be synthesized as the definition of a new approach, methodology and tools for the
environmental and cost consideration in the design process. This research work is a step toward the
development of an innovative EcoDesign approach and tool by linking IT systems and lifecycle
methodologies: PLM software and LCA-LCC methods. This approach represent an EcoDesign method
that take into consideration environmental and lifecycle cost aspects into the product development
process, the developed tool enable the designer to evaluate different design alternatives easily and
rapidly during the early product development phase. By this way is possible to design green products
taking into consideration the environmental lifecycle impact and also the lifecycle cost aspect of the
product.

Full textAbstract:
Does the lead industry have a future, in the face of the developing environmental challenge? This thesis addresses this question and concludes, it should have for the foreseeable future, providing it adopts the changes detailed. These changes are posited within a framework, which consists of a strategy, approaches and tools. The changes are both technical and philosophical. They are technical, in the sense that the tools and approaches provide practical means whereby the environmental `risks' may be identified, assessed and managed. They are philosophical, because they set out and identify the features of a new conceptual paradigm, whose basis is in the concept of the `risk society'. The paradigm is significantly more holistic, multi-dimensional, inherently flexible, and is intended to be reflexive. Adoption of the elements of the framework, will facilitate a more effective establishment, and management of environmental `risk' credentials, which will help encourage better environmental decision making. Hence, it will facilitate, the balancing of resource consumption and environmental impact costs, versus social and economic benefits, in an improved manner. The modelling approaches, and selected inventory and environmental impact assessment tools, enclosed within this thesis, have been designed to facilitate the development of, and to function within, the new paradigm. These have been developed for BRM and MIM case studies, and function at the site-specific and the cradle-to-gate scales. The former consider the company site of Britannia Refined Metals (BRM) Ltd., where refining to produce primary and secondary refined lead products takes place, whilst the latter consider the life-cycle of the refined primary lead products of MIM Ltd. The modelling approaches have also been designed so, that they may be re-aggregated into models able to operate at many different scales, as required. The framework, and its elements, are applicable for all industries facing similar challenges.

Protective relays are important parts of the power system. The protection guards valuable equipment, and protective relays play a vital role in performing the task. The relay detects fault conditions within an assigned area, opens and closes output contacts to cause the operation of other devices under its control. The relay acts to operate the appropriate circuit breakers to prevent damage to personnel and property. To ensure consistent reliability and proper operation, protective relay equipment must be evaluated and tested.
The importance of the relay evaluation issue is linked to capability to test the relays and relaying systems using very accurate waveform representation of a fault event. The purpose of testing protective relays is to ensure correct operation of the relay for all possible power system conditions and disturbances. To fulfill this purpose, relay testing in varying network configurations and with different fault types is required. There are a variety of options that have different performance potentials and implementation constraints. Use of digital simulators to test protective relays has proven to be an invaluable mean to evaluate relay performance under realistic conditions.
This thesis describes a new methodology that attempts to improve the existing practices in testing relays by using advanced digital simulator hardware, different software packages for network modeling, and new software tools for generating and replaying test waveforms.
Various types of microprocessor relays are tested and evaluated through the set of scenarios. New methodology that combines different software packages to facilitate particular testing objectives is applied.

Full textAbstract:
One of the main performance criteria for a machine tool is its ability to manufacture dimensionally and geometrically accurate parts. In this context evaluation of the geometric and kinematic accuracy of machine tools is important for achieving a high accuracy of machine parts. Moreover, the potential of predicting the accuracy of the machine tool outcome would benefit by reducing the non-value adding operations of machined parts measurement. The aim of this thesis is to develop a methodology for modeling geometric errors of machine tools in order to evaluate the geometric and kinematic accuracy and estimate the machined part accuracy by predicting the error motion of the machine tool for a given toolpath. The thesis consists of the description of the methodology that includes and explains aspects necessary for the development of the machine geometric error model. Additionally, a laser interferometer measurement process of the geometric errors and the various parameters necessary for the model development is presented. A three axis machine tool is utilized in order to investigate and analyze the model and to measure the geometric errors. An analysis is made for evaluating the accuracy of the machine tool. Finally, a computational implementation of the model is made and two simple toolpaths are generated in order to demonstrate the potential of the model in predicting the geometric errors of the machine.<br>En av de viktigaste prestationskriterierna för en verktygsmaskin är dess förmåga att tillverka dimensionellt och geometriskt korrekta delarna.

Full textAbstract:
This thesis describes the findings of an industrial survey that identified the context of use for software development projects. This context of use is parameterised and combined with a categorisation of UIDT functionality to produce an extensible and tailorable reference model or framework for UIDT evaluation and selection. An accompanying methodology - which together with the framework is known as SUIT (Selection of User Interface Development Tools) - guides the use of the framework such that project-specific context of use can be modelled and thereafter systematically considered during UIDT selection. This thesis proposes that such focussed and documented consideration of context of use during UIDT selection increases the quality of a selection decision and therefore facilitates reuse of UIDT evaluation and selection results. An evaluative study is described which demonstrates the effectiveness and viability of the SUIT framework and methodology as a paper-based UIDT evaluation facility. The same study also identifies the need for a computer-based tool to support the management of UIDT evaluation data and to assist its comparison and analysis. Experiences with this study, the results of the industrial study, and the structure of the framework and methodology provided input into a set of requirements for a computer-based visualisation environment that supports the comparison and analysis of UIDT data. The SUIT data visualisation environment and its qualitative evaluation are described. The evaluation results identify the usefulness and practicability of the SUIT approach when supported by the visualisation environment. They also suggest a number of refinements and extensions to the tool. The results provide an initial corpus of knowledge regarding practical strategies used by evaluators to compare and analyse UIDT evaluation data. These strategies are modelled using a novel purpose-built graphical notation that focuses on sequencing, flexibility, and patterns of activity.

Au cours de la dernière décennie, la conception des systèmes embarqués a évolué dans l'optique d'augmenter la puissance de calcul tout en conservant une faible consommation d'énergie. À titre d'exemple, les véhicules autonomes tels que les drones sont un domaine d'application représentatif qui combine de la vision, des communications sans fil avec d'autres noyaux de calculs intensifs, le tout avec un budget énergétique limité. Avec l'avènement des systèmes multicœurs sur puce (MpSoC), la simplification des processeurs a diminué la consommation d'énergie par opération, alors que leur multiplication a amélioré les performances. Cependant, l'apparition du phénomène de ''dark silicon'' a conduit à l'intégration d'accélérateurs matériels spécialisés au sein des systèmes multicœurs. C'est ainsi que sont nées les architectures massivement multicœurs hétérogènes (HMpSoC) combinant des processeurs généralistes (SW) et des accélérateurs matériels (HW). Pour ces architectures hétérogènes, les performances et la consommation d'énergie dépendent d'un large ensemble de paramètres tels que le partitionnement HW/SW, le type d'implémentation HW et le coût de communication entre les organes de calcul HW et SW conduisant ainsi à un immense espace de conception. Dans cette thèse, nous étudions des méthodes permettant la réduction de la complexité de développement et de mise en oeuvre d'applications efficaces en énergie sur HMpSoC. De nombreuses contributions sont proposées pour améliorer les outils d'exploration de l'espace de conception (DSE) avec des objectifs énergétiques. Tout d'abord, une définition formelle de la structure HMpSoC est introduite ainsi qu'une méthode de représentation générique axée sur la hiérarchie mémoire. Ensuite, un outil de modélisation rapide de l'énergie est proposé et validé sur plusieurs applications. Ce modèle énergétique sépare les sources d'énergie en trois catégories (calcul statique, dynamique et communications) et calcule leurs contributions sur la consommation globale de manière indépendante. Basée sur une étude précise des communications, cette approche calcule rapidement la consommation d'énergie pour une répartition donnée d'application sur un HMpSoC. Dans un deuxième temps, nous proposons une méthodologie permettant l'exploration énergétique d'accélérateurs sur HmpSoC. Cette méthode s'appuie sur le modèle de consommation précédent couplé à une formulation de programmation linéaire en nombre entier mixte (MILP). Cela permet de sélectionner efficacement les accélérateurs HW et le partitionnement HW/SW et ainsi d'obtenir une implémentation efficace en énergie pour une application tuilée. Les expériences réalisées ont montré la complexité du processus de validation d'outils/algorithmes de DSE sur une large gamme d'applications et d'architectures. Afin de résoudre ce problème, nous proposons un simulateur d'architectures HMpSoC intégrant un modèle de consommation permettant d'observer l'exécution d'applications. La structure de l'architecture cible est décrite à l'aide d'un fichier de configuration basé sur le modèle de représentation générique précédent. Ce fichier est chargé dynamiquement lors du démarrage du simulateur. De plus, ce simulateur est associé à un générateur d'applications permettant la création d'un large ensemble d'applications représentatives du domaine. Ce générateur se base sur un ensemble de schémas de calcul et de communication élémentaire qu'il combine pour obtenir une application complète. Les applications ainsi obtenues peuvent être enrichies par des informations de placement et automatiquement exécutées sur le simulateur. Cet ensemble d'outils a pour objectif de faciliter la validation de nouveaux algorithmes ciblant le placement efficace en énergie d'application sur une large gamme d'architectures HMpSoC<br>During the last decade, the design of embedded systems was pushed to increase computational power while maintaining low energy consumption. As an example, autonomous vehicles such as drones are a representative application domain which combines vision, wireless communications and other computation intensive kernels constrained with a limited energy budget. With the advent of Multiprocessor System-on-Chip (MpSoC) architectures, simplification of processor cores decreased power consumption per operation, while the multiplication of cores brought performance improvement. However, the ''dark silicon'' issue led to the benefit of augmenting programmable processors with specialized hardware accelerators and to the rise of Heterogeneous MpSoC (HMpSoC) combining both software (SW) and hardware (HW) computational resources. For these heterogeneous architectures, performance and energy consumption depend on a large set of parameters such as the HW/SW partitioning, the type of HW implementation or the communication cost between HW and SW cores therefore leading to a huge design space. In this thesis, we study how to reduce the development and implementation complexity of energy-efficient applications on HMpSoC. Multiple contributions are proposed to enhance Design Space Exploration (DSE) tools with energy objectives. First, a formal definition of HMpSoC structure is introduced alongside with a generic representation focused on the memory hierarchy. Then, a fast power modelling tool is proposed and validated on several applications. This power model separates the power sources in three families (static, dynamic computation and dynamic communication) and computes their contributions on global consumption independently. With a fine grain communications study, this approach rapidly computes energy consumption for a given application mapping on a HMpSoC. In a second time, we propose a methodology for energy-driven accelerator exploration on HMpSoC. This method builds upon the previous power model coupled with an Mixed Integer Linear Programming (MILP) formulation and enables to efficiently select HW accelerators and HW/SW partitioning which achieve energy efficient-mapping of a tiled application. The experiments involved in these contributions show the complexity of DSE validation process on a wide range of applications and architectures. To address these issues, we introduce a HMpSoC simulator embedding a power model to monitor application execution. Properties of targeted architectures are described, at run-time with the previous generic representation model. Furthermore, this simulator is coupled with an application generator framework that could build an infinite set of representative applications following predefined computation models. The obtained applications could then be enriched with mapping directive and executed on the simulator. This combination enables to ease the research and validation of new DSE algorithms targeting energy-aware application mapping on a wide range of HMpSoC architectures

Full textAbstract:
The traditional product development process has been sequential in nature, with the product going through design, process planning, manufacturing and assembly. This sequential decision making results in increased costs and higher product development times. With the trend towards better product quality, product customization, shorter product life cycle, and international competition, manufacturers are faced with the challenge of improving product quality while reducing product development time, manufacturing lead-time, and product cost. To cope with these challenges, the product development process has to be made more efficient by integrating manufacturing and assembly considerations in the design phase itself, through the use of techniques such as Design For Manufacturability (DFM) and Design For Assembly (DFA).
DFM techniques have to be automated to take advantage of the vast advances in CAD and CAM systems. However, the automation of DFM has been constrained, especially for machined components, by the lack of methodologies which are dependent on the process of manufacture, and the incomplete part data representation in CAD systems. This research created a DFM methodology for machined components, along with an appropriate data representation scheme. Also, a software prototype was developed to demonstrate and validate both the methodology and the data structure.
The DFM methodology consists of three modules: DFM feasibility, process plan generation, and DFM analysis. The DFM feasibility module performs an initial feasibility check on the material, dimensions, tolerances, and configuration of the part. It also generates the spatial relationships between features. The process plan generation module uses a sequence identifier algorithm to generate the manufacturing sequence. The DFM analysis module evaluates tolerances relative to their stacking effects and manufacturability. It then analyzes the part configuration for possible design and process plan improvements.
A software prototype was developed using C++. It addresses the dimension checking, tolerance checking, configuration checking and spatial relationships generation in the DFM feasibility module. In the process plan generation module, the sequence of surfaces/features to be generated has been automated. This sequence is one of the major inputs to a computer-aided process planning module.
Other methodologies for non-machined components can be easily integrated into the DFM framework for complete automation of DFM analysis.<br>Ph. D.

The goal of this research is to create a methodology that measures the robustness and effectiveness of forensic tools' ability to detect data hiding. First, an extensive search for any existing guidelines testing against data hiding was performed. After finding none, existing guidelines and frameworks in cybersecurity and cyber forensics were reviewed. Next, I created the methodology in this thesis. This methodology includes a set of steps that a user should take to evaluate a forensic tool. The methodology has been designed to be flexible and scalable so as new anti-forensic data hiding methods are discovered and developed, they can easily be added to the framework, and the evaluator using the framework can tailor it to the files they are most focused on. Once a polished draft of the entire methodology was completed, it was reviewed by information technology and security professionals and updated based on their feedback.Two popular forensic tools – Autopsy/Sleuthkit and X-Ways – were evaluated using the methodology developed. Evaluation revealed improvements in the methodology that were updated. I propose that the methodology can be an effective tool to provide insight and evaluate forensic tools.

Full textAbstract:
Standards play a big role in a lot of professions and when it comes to most aspects of law enforcement and forensic investigation, it’s no different. Despite that, for some reason, there aren’t any for when it comes to evaluating and choosing forensic tools. The lack of an international standard for evaluating forensic tools has a clear negative impact on the digital forensics community as it lowers the value of tool tests and evaluations and hinders both the reproducibility and verification of their results. Most tool evaluations are performed with custom forensic images and measures metrics that are not scientifically motivated, but rather made up based on the evaluator's personal preferences. By examining current standards and related work done in the field, a new methodology is proposed. It builds on scientific principles and the strengths of existing literature. The methodology is then tested in a practical experiment. The result of the paper is a solid foundation for a new standard to be built upon.

Full textAbstract:
Axial compressors are widely used in many aerodynamic applications. The design of an axial compressor configuration presents many challenges. Until recently, compressor design was done using 2-D viscous flow analyses that solve the flow field around cascades or in meridional planes or 3-D inviscid analyses. With the advent of modern computational methods it is now possible to analyze the 3-D viscous flow and accurately predict the performance of 3-D multistage compressors. It is necessary to retool the design methodologies to take advantage of the improved accuracy and physical fidelity of these advanced methods.
In this study, a first-principles based multi-objective technique for designing single stage compressors is described. The study accounts for stage aerodynamic characteristics, rotor-stator interactions and blade elastic deformations. A parametric representation of compressor blades that include leading and trailing edge camber line angles, thickness and camber distributions was used in this study A design of experiment approach is used to reduce the large combinations of design variables into a smaller subset. A response surface method is used to approximately map the output variables as a function of design variables. An optimized configuration is determined as the extremum of all extrema.
This method has been applied to a rotor-stator stage similar to NASA Stage 35. The study has two parts: a preliminary study where a limited number of design variables were used to give an understanding of the important design variables for subsequent use, and a comprehensive application of the methodology where a larger, more complete set of design variables are used. The extended methodology also attempts to minimize the acoustic fluctuations at the rotor-stator interface by considering a rotor-wake influence coefficient (RWIC). Results presented include performance map calculations at design and off-design speed along with a detailed visualization of the flow field at design and off-design conditions.
The present methodology provides a way to systematically screening through the plethora of design variables. By selecting the most influential design parameters and by optimizing the blade leading edge and trailing edge mean camber line angles, phenomenon s such as tip blockages, blade-to-blade shock structures and other loss mechanisms can be weakened or alleviated. It is found that these changes to the configuration can have a beneficial effect on total pressure ratio and stage adiabatic efficiency, thereby improving the performance of the axial compression system. Aeroacoustic benefits were found by minimizing the noise generating mechanisms associated with rotor wake-stator interactions. The new method presented is reliable, low time cost, and easily applicable to industry daily design optimization of turbomachinery blades.

Although information systems have had a great impact on environmental information, they can still influence how the environment is protected through the use of new technology. In this study, it was revealed that while the majority of people, including citizens, environmental experts and related civil servants are active and collaborate in this domain, they are still concerned about it. While information is found to be a key player, it is necessary to find a system that can lead it from the source to the proper destination. Consequently this study investigates how environmental information can be shared and more easily accessed. Different actors in the system create the opportunity to have more holistic view of the problem at hand. Soft systems methodology inspires me to draw requirements of different groups of actors, represent diverse conceptual models of their desired system and eventually examine a proposed information system. The study characterises a framework for employing Web 2.0 technology to facilitate the collaboration and coordination of environmental information with the goal of protecting the environment.

Abstract
Growing environmental concerns caused by increasing consumption of natural resources and pollution need to be addressed. Manufacturing dictates the efficiency with which resource inputs are transformed into economically valuable outputs in the form of products and services. Consequently, it is also responsible for the resulting waste and pollution generated from this transformation process.
In particular, energy efficiency is one of the main issues when tackling resources consumption reduction in manufacturing, as manufacturing industry is responsible for 90% of industry energy consumptions, in turn making up the 51% of global energy usage (U.S. Energy Information Administration).
This research explored and addressed the challenge of Energy Performance Management in manufacturing, as it constitutes the first, critical step to understand energy behaviours, to identify energy management opportunities and to evaluate energy savings. This activity has become always more important in the last decades, as Energy Management Systems and energy management practices based on continuous improvement and people engagement have been largely adopted, requiring the introduction of new energy consumption control systems capable to identify the standard operative energy behaviour and performance of systems and machines and their energy baseline, to point out contingent deviations of energy performances from the baseline and to identify possible causes and clearly attribute responsibilities of such deviations. In this context, several attempts have been presented in literature trying to identify methods to create Energy Performance Indicators so as to satisfy these requirements, but a proper system to monitor and control their evolution over time is neglected. In addition, most of the proposed approaches envisages the use of huge amounts of data and of Internet of Things (IoT)/Machine Learning (ML) techniques, that are not always available or promptly applicable, mainly due to the scarceness and low quality of data. Thus, consumption control tools have been proposed, refined and tested as well as a framework to help companies in the selection of the most suitable tool basing on their needs and available data and information.
The work started with a review of existing theories about energy efficiency measures and control methodologies and of available tools. This review provided a strong foundation to approach the issues Energy Performance Management in manufacturing and helped defining research and research-practice gaps as well as main research questions. The applicability of most common approaches was then tested by the means of a massive survey regarding data availability, and the need of a framework to help companies selecting the most suitable tools and to assist their transition towards Industry 4.0 in Energy Performance Management was stated. Three different approaches and related tools for Energy Performance Management were then developed and tested in different companies; these tools are respectively based on simulation, statistical data analysis and Artificial Neural Networks (ANNs, or more in general machine learning techniques), thus requiring different assets and addressing different companies’ needs. The proposed methodology and tools were tested with the development of different industrial cases. Finally, basing on specific companies’ needs identification in the industrial cases analysed, criteria were defined to help companies identifying the most suitable tool to be implemented and a decision support tool was developed.M.Benedetti - Energy Performance Management in manufacturing: methodology, tools and

Background – Enhanced social research interviews seek to engage interviewees in extended conversation-like dialogues where they are empowered to produce output by discussing themes of relevance to them. Photos, videos, vignettes and other enhancing tools have been used before in social sciences research interviews to contextualise the interview interaction. Initial Assumption – Sacred texts (such as excerpts from the Bible and the Quran) enjoy some features that make them potential tools to enhance research interviews. This study set out to answer the Research Question: ‘What are the benefits and challenges of using sacred texts as tools to enhance social research interviews?’ Methodology – Selected Biblical and Quranic verses were used in three sets each, to start social discussions with fifteen Christian and thirteen Muslim participants, respectively, in semi-structured interviews. Findings – The findings of this empirical study show that using sacred texts was perceived favourably by the participants, enhanced the dynamics of the interviews and provided a platform to produce data that are rich, varied and nuanced. Conclusion – This research points out the usefulness of sacred texts – as enhancing tools – when used in social research interviews to produce natural conversations that, in turn, lead to rich, nuanced data. This suggests that sacred texts can be added to the qualitative research interview-enhancing toolbox especially with exploratory studies that are open for emerging themes during interview settings. Research areas where sacred texts can be used in interviews include: ethics, social relations, gender roles, psychology, moral choices, cultural studies and spirituality, among other social sciences disciplines. Researchers as well as participants will be expected to have a degree of familiarity with the sacred book or texts to make both interviewers and interviewees interested enough in discussing it in an open and respectful setting.

Full textAbstract:
In many industrial experiments, completely randomized designs (CRDs) are impractical due to restrictions on randomization, or the existence of one or more hard-to-change factors. Under these situations, split-plot experiments are more realistic. The two separate randomizations in split-plot experiments lead to different error structure from in CRDs, and hence this affects not only response modeling but also the choice of design. In this dissertation, two graphical tools, three-dimensional variance dispersion graphs (3-D VDGs) and fractions of design space (FDS) plots are adapted for split-plot designs (SPDs). They are used for examining and comparing different variations of central composite designs (CCDs) with standard, V- and G-optimal factorial levels. The graphical tools are shown to be informative for evaluating and developing strategies for improving the prediction performance of SPDs. The overall cost of a SPD involves two types of experiment units, and often each individual whole plot is more expensive than individual subplot and measurement. Therefore, considering only the total number of observations is likely not the best way to reflect the cost of split-plot experiments. In this dissertation, cost formulation involving the weighted sum of the number of whole plots and the total number of observations is discussed and the three cost adjusted optimality criteria are proposed. The effects of considering different cost scenarios on the choice of design are shown in two examples. Often in practice it is difficult for the experimenter to select only one aspect to find the optimal design. A realistic strategy is to select a design with good balance for multiple estimation and prediction criteria. Variations of the CCDs with the best cost-adjusted performance for estimation and prediction are studied for the combination of D-, G- and V-optimality criteria and each individual criterion.<br>Ph.

Dawson (2009) suggested a twelve step methodology for implementing knowledge management solutions following research which showed that implementing knowledge management solutions was not as successful as expected. This thesis investigates the third of this twelve step methodology which requires finding a knowledge management solution in the context of the problem. The aim of the research is to determine a methodology that will provide a systematic way for managers to select an appropriate knowledge management tool given a particular working environment. Two organisations are investigated to confirm that there is a need for a systematic methodology for selecting knowledge management tools and how a methodology may help in achieving selecting an appropriate tool. This investigation is carried out using case studies, action research and interviews and results in discovering that organisations do not have a systematic method for selecting tools which leads to tools being selected haphazardly and not always successfully. Two tools are developed to aid a manager in selecting a knowledge management tool: the House of Knowledge Management Tool Selection and the Knowledge Management Tool Classification Grid. The House tool helps to identify the knowledge problem being solved and evaluates all potential knowledge management tools against the problem. The barriers to the potential success of the tools are also examined. The grid identifies potential tools by classifying them against knowledge problems. The two tools are further refined and developed using the two organisations as case studies to demonstrate how and when the tools can be used. This leads to development of the Barrier House and the Evaluation Grid. A framework and associated methodology are then developed that can be used as a guide to using the tools, offering a systematic approach to selecting knowledge management tools given any environment and thus accomplishing the aim of the thesis.

Full textAbstract:
Engineering aircraft systems is a complex task. Therefore models and computer simulations are needed to test functions and behaviors of non existing systems, reduce testing time and cost, reduce the risk involved and to detect problems early which reduce the amount of implementation errors. At the section Vehicle Simulation and Thermal Analysis at Saab Aeronautics in Linköping every basic aircraft system is designed and simulated, for example the fuel system. Currently 2-dimensional rectangular blocks are used in the simulation model to represent the fuel tanks. However, this is too simplistic to allow a more detailed analysis. The model needs to be extended with a more complex description of the tank geometry in order to get a more accurate model. This report explains the different steps in the developed methodology for combining 3-dimensional geometry models of any fuel tank created in CATIA with dynamic simulation of the fuel system in Dymola. The new 3-dimensional representation of the tank in Dymola should be able to calculate fuel surface location during simulation of a maneuvering aircraft. The first step of the methodology is to create a solid model of the fuel contents in the tank. Then the area of validity for the model has to be specified, in this step all possible orientations of the fuel acceleration vector within the area of validity is generated. All these orientations are used in the automated volume analysis in CATIA. For each orientation CATIA splits the fuel body in a specified number of volumes and records the volume, the location of the fuel surface and the location of the center of gravity. This recorded data is then approximated with the use of radial basis functions implemented in MATLAB. In MATLAB a surrogate model is created which are then implemented in Dymola. In this way any fuel surface location and center of gravity can be calculated in an efficient way based on the orientation of the fuel acceleration vector and the amount of fuel. The new 3-dimensional tank model is simulated in Dymola and the results are compared with measures from the model in CATIA and with the results from the simulation of the old 2-dimensional tank model. The results shows that the 3-dimensional tank gives a better approximation of reality and that there is a big improvement compared with the 2-dimensional tank model. The downside is that it takes approximately 24 hours to develop this model.<br>Att utveckla ett nytt flygplanssystem är en väldigt komplicerad arbetsuppgift. Därför används modeller och simuleringar för att testa icke befintliga system, minska utvecklingstiden och kostnaderna, begränsa riskerna samt upptäcka problem tidigt och på så sätt minska andelen implementerade fel. Vid sektionen Vehicle Simulation and Thermal Analysis på Saab Aeronautics i Linköping designas och simuleras varje grundflygplanssystem, ett av dessa system är bränslesystemet. För närvarande används 2-dimensionella rätblock i simuleringsmodellen för att representera bränsletankarna, vilket är en väldigt grov approximation. För att kunna utföra mer detaljerade analyser behöver modellerna utökas med en bättre geometrisk beskrivning av bränsletankarna. Denna rapport går igenom de olika stegen i den framtagna metodiken för att kombinera 3- dimensionella tankmodeller skapade i CATIA med dynamisk simulering av bränslesystemet i Dymola. Den nya 3-dimensionella representationen av en tank i Dymola bör kunna beräkna bränsleytans läge under en simulering av ett manövrerande flygplan. Första steget i metodiken är att skapa en solid modell av bränslet som finns i tanken. Därefter specificeras modellens giltighetsområde och alla tänkbara riktningar hos accelerationsvektorn som påverkar bränslet genereras, dessa används sedan i den automatiserade volymanalysen i CATIA. För varje riktning delar CATIA upp bränslemodellen i ett bestämt antal delar och registrerar volymen, bränsleytans läge samt tyngdpunktens position för varje del. Med hjälp av radiala basfunktioner som har implementerats i MATLAB approximeras dessa data och en surrogatmodell tas fram, denna implementeras sedan i Dymola. På så sätt kan bränsleytans och tyngdpunktens läge beräknas på ett effektivt sätt, baserat på riktningen hos bränslets accelerationsvektor samt mängden bränsle i tanken. Den nya 3-dimensionella tankmodellen simuleras i Dymola och resultaten jämförs med mätningar utförda i CATIA samt med resultaten från den gamla simuleringsmodellen. Resultaten visar att den 3-dimensionella tankmodellen ger en mycket bättre representation av verkligheten och att det är en stor förbättring jämfört med den 2-dimensionella representationen. Nackdelen är att det tar ungefär 24 timmar att få fram denna 3-dimensionella representation.

A tracking system that serves as a tool for tracking the movement of surgical instruments has been developed. The system tracks color markers on the surgical instruments. The Continuously Adaptive Mean Shift (CAMSHIFT) methodology was employed for tool tracking and a total distance traversed by the surgical instrument of interest was calculated. Two cameras were used to record the motion of the tool and the software developed was used to track the movement of markers on the tools over subsequent frames. The information thus derived from the two views of cameras was used to calculate the three dimensional coordinates of the location of the marker on the instrument and subsequently the distance traversed. MATLAB, which is a commercial software package, was used to implement the tool tracking algorithm and for developing the GUI (Graphic User Interface). Data was collected using Commercial off the shelf (COTS) camera hardware and processing was done on a 2.2 GHz, 512 MB RAM Intel Pentium 4 computer.

Full textAbstract:
The disciplines of space and time form two domains to which it is daring to compare, since it is obvious that they are of a different nature. Music happens in time, while architecture happens in space. However, from the first treatises on both architecture and music, repeated calls for comparison, complementarity and influence of both disciplines can be read, at least to the observation of certain common orders between the two domains. In this doctoral thesis we do not question this whole theoretical corpus that has been enriching the relationship between both disciplines. We received it and joined that stream of knowledge. What we do notice, however, is the almost impertinent question that follows: can sound help the architect in his daily tasks? And, therefore, what are the contributions of sound to the architect? To do this we must seek the connection in the principles of both arts, where we can detach ourselves from time and space, and approach the most universal of art forms.
The architect, in his daily work, is faced with three particular tasks: the architectural project, the architectural analysis and the teaching of architecture. Each of the three tasks is connected with the other two tasks: the project is carried out again with the analysis and transmitted to the new architect; the analysis supports the project decisions and gives tools to the disciple; and the teaching has the project as its purpose and the analysis as its method. The thesis presented here shows what sound offers to the task of the project, to that of analysis and to that of teaching. These three tasks are approached from three premises: theoretical foundations, tools and evaluation. The interaction of the three tasks with the three premises gives rise to nine lines of work that articulate the chapters of the thesis.
The first, fourth and seventh chapters approach the three tasks from the premise of theoretical foundations, foundations that perhaps because they are obvious, have been ignored or overlooked but which constitute the nature of both disciplines. The first shows, by the hand of two 20th century authors - the architect Dom Hans van der Laan and the composer Olivier Messiaen - that creation in both disciplines is of a systematic nature. The fourth one revaluates the analytical systems of representation of form both in architecture and in music which, starting with the basic characteristics of its elements, lead to a symbolic notation and a tool for the analysis of the work: the plan and the score. The seventh introduces the student of architecture to the growing separation between music and architecture that has been accentuated to this day.
The second, fifth and eighth chapters approach the three particular tasks from the premise of tools, working tools that help to understand more directly the influence of architecture on sound. The second places virtual reality and auralization techniques at the service of the architectural and urban planning project, enhancing the sound experience in these projects. The fifth deals with the acoustic analysis of exterior spaces and their relationship with the urban configuration of these spaces. The eighth section presents the study of acoustic heritage as an educational tool.
The third, sixth and ninth chapters deal with the three tasks from the premise of evaluation, a check that ensures the influence of sound on them through teaching experiments. The third argues and exemplifies that a sound landscape can be the engine and generator of an architectural design. The sixth one reviews the methods for evaluating the subjective and objective parameters of architectural acoustics. The ninth shows that in teaching sound to architects, "learning by listening" should be given priority over "passive learning".<br>Las disciplinas del espacio y del tiempo forman dos dominios a los que resulta atrevido comparar, pues es obvio que son de naturaleza distinta. La música ocurre en el tiempo, mientras que la arquitectura en el espacio. No obstante, desde los primeros tratados tanto de arquitectura como de música, se pueden leer repetidas llamadas a la comparación, al complemento y a la influencia de ambas disciplinas, cuanto menos a la constatación de ciertos órdenes comunes entre ambos dominios. En esta tesis doctoral no ponemos en cuestión todo este corpus teórico que ha venido enriqueciendo la relación entre ambas disciplinas. La recibimos y nos unimos a esa corriente de conocimiento. En lo que sí reparamos, en cambio, es en la pregunta casi impertinente que surge seguidamente: ¿puede el sonido ayudar al arquitecto en sus tareas diarias? Y, por tanto, ¿cuáles son las contribuciones del sonido para el arquitecto? Para ello debemos buscar la conexión en los principios de ambas artes, allí donde podemos despegarnos del tiempo y del espacio, y acercarnos a la más universal de las formas de arte. El arquitecto, en su tarea diaria, se enfrenta a tres tareas particulares: el proyecto arquitectónico, el análisis arquitectónico y la enseñanza de la arquitectura. Cada una de las tres tareas está conectada con las otras dos: el proyecto se reconduce con el análisis y se transmite al nuevo arquitecto; el análisis soporta las decisiones de proyecto y da herramientas al discípulo; y la enseñanza tiene como fin el proyecto y como método el análisis. La tesis aquí presentada pone de manifiesto lo que el sonido ofrece a la tarea del proyecto, a la del análisis y a la de la enseñanza. Estas tres tareas son abordadas desde tres premisas: los fundamentos teóricos, las herramientas y la evaluación. La interacción de las tres tareas con las tres premisas da lugar a nueve líneas de trabajo que articulan los capítulos de la tesis. Los capítulos primero, cuarto y séptimo abordan las tres tareas desde la premisa de los fundamentos teóricos, fundamentos que quizá por ser obvios, se han obviado o pasado por alto pero que constituyen la naturaleza de ambas disciplinas. El primero muestra, de la mano de dos autores del siglo XX ?el arquitecto Dom Hans van der Laan y el compositor Olivier Messiaen- que la creación en ambas disciplinas es de naturaleza sistemática. El cuarto revaloriza los sistemas analíticos de representación de la forma tanto en arquitectura como en música que, empezando por las características básicas de sus elementos, conducen a una notación simbólica y una herramienta de análisis de la obra: el plano y la partitura. El séptimo presenta al estudiante de arquitectura la creciente separación entre la música y la arquitectura que se ha venido acentuando hasta nuestros días. Los capítulos segundo, quinto y octavo abordan las tres tareas particulares desde la premisa de las herramientas, útiles de trabajo que ayudan a comprender de modo más directo la influencia de la arquitectura en el sonido. El segundo sitúa la realidad virtual y las técnicas de auralización al servicio del proyecto de arquitectura y urbanismo, potenciando la experiencia sonora en estos proyectos. El quinto aborda el análisis acústico de espacios exteriores y su relación con la configuración urbana de estos espacios. El octavo presenta el estudio del patrimonio acústico como herramienta pedagógica. Los capítulos tercero, sexto y noveno abordan las tres tareas desde la premisa de la evaluación, comprobación que asegura mediante experimentos docentes la influencia del sonido en ellas. El tercero argumenta y ejemplifica que un paisaje sonoro puede ser el motor y generador de un diseño arquitectónico. El sexto realiza una revisión de los métodos de evaluación de los parámetros subjetivos y objetivos de la acústica arquitectónica. El noveno muestra que en la enseñanza del sonido para los arquitectos debe priorizarse "aprender escuchando" antes que el "aprendizaje pasivo".

Many organizations have legacy applications and strive to modernise them in order to react on changes and adapt to the new environment, the cloud. The enticements are quite a few but the risks are lurking as well. How to migrate a legacy application to the cloud is an unanswered question for many organizations. We look at how research has answered this question and the methods and tools they provide. The research partially answers the question of migration of legacy application to the cloud. The methods and tools are still quite granular, not that automated and is very dependent of what type of legacy application and the aim of the end result is.

Full textAbstract:
Natural ventilation of buildings has the potential to significantly reduce energy consumption related to cooling and fanning. This can be achieved by providing good indoor air quality without any electricity demand and improving thermal comfort in the summer through increased daytime airspeed and high night ventilation rates. In high-rise buildings, however, natural ventilation is still not a widely preferred means of ventilation.
The main reason is the lack of information on the required system design. Evaluation tools and instruments are not suitable for complex flow path design. Only few results are available on the performance of naturally ventilated high-rise buildings, especially where energy conservation is considered.
The current thesis is predicated on this research gap. The existing barriers for implementing passive technologies can be lowered by creating a quantifiable framework that accounts for all the relevant input parameters in the design process. In order to reach this goal, a planning and simulation approach is developed. Simulations results are compared to those of a reference case-study.
The 28-floor ‘Kanyon’ office tower, situated in Istanbul, is selected to demonstrate the applicability. From the energy metering, it is concluded that mechanical cooling and ventilation result in significant electricity consumption. Detailed information on the building and its operation has been made available by the building management. In addition, the impact of different moderate climates is analysed.
The primary objectives of the thesis can be stated as the development of a design approach, and the investigation of the feasibility of the proposed design, based on an existing case-study building virtually adapted. The approach is developed in three steps, including conceptual design considerations, the development of a preliminary design tool, and a detailed design development.
In the first step, an architectural concept is developed for wide-shaped high-rise buildings where it is impossible to realise simple cross or single-sided ventilation. Conceptual adaptations addressing the flow-path design are a central chimney strategy in respect to the building width, isolated, modular segments in respect to the building height and opposed, wind adapting openings. Other solutions proposed for passive cooling are improved shading devices and activation of the structural mass for night-time ventilation.
In the second step, the originally developed ‘HighVent’ planning tool is introduced. Simple electrical circuit analogies, for both ventilation and thermal models, are found to be suitable in supporting the passive system planning. As classic design day conditions are too strict for passive system design, meaningful boundary conditions are provided. Openings can be sized automatically including an optimization process. The program first calculates the flow-path for a given airflow rate with unchanging boundary conditions. These values are then provided to the thermal module, which calculates the dynamic thermal comfort. The procedure is repeated till the system size is sufficient for passive cooling.
In the third step, the annual performance is exemplarily modelled with EnergyPlus building energy simulations including airflow networks and controls. This includes the ‘HighVent’ tool preliminary design outputs, the conceptual adaptations made, and the remaining features of the as-built Kanyon building.
The design approach is then further evaluated by comparing mechanical operation with an operation based on passive and hybrid control. Indicators proposed to evaluate the functionality are the energy consumption compared to that of mechanical ventilation and cooling systems, and compliance with the thermal comfort limits; additional aspects are the ventilation rates and the indoor air quality reached.
Simulation results indicate that properly designed and controlled natural ventilation shows a good functionality. Control over the openings is crucial, as otherwise ventilation rates can get too high and the rooms tend to cool down too much even during summer. It is shown that the ‘Adaptive Temperature Amplifier’ control algorithm developed is very robust. Differences in climate have a varying impact. For example, in the climate of Stuttgart, further adaptations to the preliminary design are not necessary, whereas in Istanbul adaptations might be reasonable. However, to satisfy the comfort expectations in Turin, there is a necessity for adaptations or a hybrid cooling concept. That humidity values meet comfort expectations must be discussed and accepted by all project stakeholders, else hybrid operation might be a good alternative.
To systematically study the possible energy conservation while maintaining thermal comfort, the energy consumption of identical buildings with different variants (passive/hybrid/active) is benchmarked against the as-built scenario. Results show that the Kanyon’s primary energy input can be reduced by approximately 30% to 40% for passive operation and by 28% to 34% for hybrid operation. This verifies the initial assumption that energy conservation of passively cooled and ventilated office spaces is significant, especially when compared to highly energy consuming state-of-the-art office towers.
The results of this research work are intended, on the one hand, to support building planners in better understanding and implementing passive cooling measures and, on the other hand, to contribute to further development of sustainable building practices.

Full textAbstract:
The Physical Vapour Deposition (PVD) magnetron sputtering process is one of the widely used techniques for depositing thin film coatings on substrates for various applications such as integrated circuit fabrication, decorative coatings, and hard coatings for tooling. In the area of coatings on cutting tools, tool life can be improved drastically with the application of hard coatings. Application of coatings on cutting tools for various machining techniques, such as continuous and interrupted cutting, requires different coating characteristics, these being highly dependent on the process parameters under which they were formed. To efficiently optimise and customise the deposited coating characteristics, PVD process modelling using RSM methodology was proposed. The aim of this research is to develop a PVD magnetron sputtering process model which can predict the relationship between the process input parameters and resultant coating characteristics and performance. Response Surface Methodology (RSM) was used, this being one of the most practical and cost effective techniques to develop a process model. Even though RSM has been used for the optimisation of the sputtering process, published RSM modelling work on the application of hard coating process on cutting tool is lacking. This research investigated the deposition of TiAlN coatings onto tungsten carbide cutting tool inserts using PVD magnetron sputtering process. The input parameters evaluated were substrate temperature, substrate bias voltage, and sputtering power; the out put responses being coating hardness, coating roughness, and flank wear (coating performance). In addition to that, coating microstructures were investigated to explain the behaviour of the developed model. Coating microstructural phenomena assessed were; crystallite grain size, XRD peak intensity ratio I111/I200 and atomic number percentage ratio of Al/Ti. Design Expert 7.0.3 software was used for the RSM analysis. Three process models (hardness, roughness, performance) were successfully developed and validated. The modelling validation runs were within the 90% prediction interval of the developed models and their residual errors compared to the predicted values were less than 10%. The models were also qualitatively validated by justifying the behaviour of the output responses (hardness, roughness, and flank wear) and microstructures (Al/Ti ratio, crystallographic peak ratio I111/1200, and grain size) with respect to the variation of the input variables based on the published work by researchers and practitioners in this field. The significant parameters that influenced the coating hardness, roughness, and performance (flank wear) were also identified. Coating hardness was influenced by the substrate bias voltage, sputtering power, and substrate temperature; coating roughness was influenced by sputtering power and substrate bias; and coating performance was influenced by substrate bias. The analysis also discovered that there was a significant interaction between the substrate temperature and the sputtering power which significantly influenced coating hardness, roughness, and performance; this interaction phenomenon has not been reported in previously published literature. The correlation study between coating characteristics, microstructures and the coating performance (flank wear) suggested that the coating performance correlated most significantly to the coating hardness with Pearson coefficient of determination value (R2) of 0.7311. The study also suggested some correlation between coating performance with atomic percentage ratio of Al/Ti and grain size with R2 value of 0.4762 and 0.4109 respectively.

Full textAbstract:
The field of software development has rapidly been changing due to changes in work requirements and expectations of stakeholders. As a result, there has been a widespread adoption of agile methodology within the software industry, as it allows for a constant stream of deliveries and project adjustments. Agile methodology allows project teams to pick and adjust appropriate agile practices as they see fit, meaning that situations differ in various ways. With respect to the young age of agile methodology and the various approaches has created gaps that could affect project efficiency and quality. Specifically, one of these unperfected areas is the task management tools, that has had a hard time being established in the digital space. This can be illustrated by the popular use analog tools such as post-it notes and whiteboards. Likewise, analog and digital task management tools have varying advantages and disadvantages that forces project teams to work in certain ways. For example, analog tools are easily adjusted and digital tool are instead more structured. Typically, this creates restrictions to the physical work space for employees and obstacles of project progression communication to external parties. Towards addressing the issue, a set of seven task board requirements are established as the foundation for the solution, which are based on the theoretical and practical findings. The solution is a digitalized whiteboard with syncing and cross platform abilities.

Currently, there is a monthly breach with its vehicle delivery policy. This policy refers to said company, it refers to a minimum of 92% of units towards the points of sale. However, in the last quarter of 2017 and the semester of 2018, it has only been met from 82% to 90%. These are 5% -10% that have not come to meet in each month, but also directly to the profitability of the company. On the one hand, storage costs are increased by each car that does not arrive or dissatisfaction is generated by the customer, this is the problem of 3 main causes, which is the installation time of radios, installation of alarms and more vehicles that are not served in the damage assessment area. As a root cause, we have the first, since, on the one hand, a bottleneck is generated by the lack of car attention and, on the other hand, represents 20% of the monthly sales of the case study, For what needs to be done to reduce this bottleneck and increase the capacity of the vehicles in this area, the damage is detailed, two lines of evaluation are carried out. This type of triage, we ensure a standardized work, since there was a group of vehicles waiting with different types of damage in the same operating line. Also, the delivery of vehicles on time is improved to 95% and the times of the areas of installation of radios, installation of alarms and damage assessment are reduced by 42.85%, 51.42% and 50% respectively.

Full textAbstract:
Knowledge Management Systems are deployed in organisations of all sizes to support the coordination and control of a range of intellectual assets, and the low cost infrastructures made available by the shift to ‘cloud computing’ looks to only increase the speed and pervasiveness of this move. However, their implementation has not been without its problems, and the development of novel interventions capable of supporting the mundane work of everyday organisational settings has ultimately been limited. A common source of trouble for those formulating such systems is said to be that some proportion of the knowledge held by a setting’s members is hidden from the undirected view of both The Organisation and its analysts - typically characterised as a tacit knowledge - and can therefore go unnoticed during the design and deployment of new technologies. Notwithstanding its utility, overuse of this characterisation has resulted in the inappropriate labelling of a disparate assortment of phenomena, some of which might be more appropriately re-specified as ‘hidden knowledges’: a standpoint which seeks to acknowledge their unspoken character without making any unwarranted claims regarding their cognitive status. Approaches which focus on the situated and contingent properties of the actual work carried out by a setting’s members - such as ethnomethodologically informed ethnography - have shown significant promise as a mechanism for transforming the role played by members’ practices into an explicit topic of study. Specifically they have proven particularly adept at noticing those aspects of members’ work that might ordinarily be hidden from an undirected view, such as the methodic procedures through which we can sometimes mean more than we can say in-just-so-many-words. Here - within the context of gathering the requirements for new Knowledge Management Systems to support the reuse of existing knowledge - the findings from the application of just such an approach are presented in the form of a Pattern Language for Knowledge Management Systems: a descriptive device that lends itself to articulating the role that such hidden knowledges are playing in everyday work settings. By combining these three facets, this work shows that it is possible to take a more meaningful approach towards noticing those knowledges which might ordinarily be hidden from view, and apply our new understanding of them to the design of Knowledge Management Systems that actively engage with the knowledgeable work of a setting’s members.

Relatório de Trabalho de Projeto apresentado para cumprimento dos requisitos necessários à obtenção do grau de Mestre em Enfermagem Médico-Cirúrgica<br>Este trabalho visa apresentar o Projeto de Intervenção em Serviço (PIS) e Projeto de Aprendizagem Clínica (PAC) realizados no Serviço de Urgência Geral (SUG) de um Centro Hospitalar da Margem Sul do Tejo, em contexto de estágio integrado no plano de estudos do 1º Curso de Mestrado em Enfermagem Médico-Cirúrgica da Escola Superior de Saúde do Instituto Politécnico de Setúbal, e fazer uma análise reflexiva sobre as aprendizagens adquiridas à luz das competências comuns e específicas do Enfermeiro Especialista em Pessoa em Situação Crítica e Mestre em Enfermagem Médico-Cirúrgica.
No PIS, abordámos uma temática relacionada com o uso de equipamentos de proteção individual (EPI) no SUG. Cientes da importância do uso de EPI na prevenção e controlo de infeção, aplicámos uma grelha de observação e um questionário à equipa de enfermagem do serviço. Após análise dos dados obtidos, fundamentámos a perceção inicial de que os enfermeiros por vezes não usavam EPI ou usavam-no de forma inadequada, potenciando a infeção associada aos cuidados de saúde (IACS). A IACS constitui um problema de saúde devido à elevada morbilidade e mortalidade e o uso de EPI faz parte integrante das precauções básicas garantindo a segurança dos profissionais e dos clientes (Pina et al, 2010). Propusemo-nos, então, divulgar boas práticas no uso de EPI desenvolvendo atividades como, formação/treino dos enfermeiros no uso de EPI, atualização do Procedimento Geral de Seleção de EPI e elaboração de instrumento de auditoria às práticas.
Após deteção de necessidades através de entrevistas não estruturadas com a equipa de enfermagem e observação na prática, desenvolvemos o PAC. Elaborámos procedimento sobre cuidados de enfermagem ao cliente com entubação endotraqueal, assim como tabela de compatibilidades de medicamentos administrados por via intravenosa e desenvolvemos estratégias relacionadas com evacuação de clientes do SUG.<br>Abstract: This paperwork aims to present Service Intervention Project (SIP) and the Clinic Apprenticeship Project (CAP) made in the General Urgency Service (GUS) of an Hospital Centre on the South Side of Tejo, in context of internship integrated in the study plan of the 1st Masters Course in Medical-Surgical Nursing of the Superior School of Health of the Polytechnic Institute of Setúbal, and to do a reflexive analysis of the learning acquired under the Specialist Nurse common and specific skills in a Critical Situation person and Master in Medical-Surgical Nursing.
In the SIP, we approach a thematic related with the use of personal protective equipment (PPE) in the. Aware of the importance of the use PPE in the prevention and control of infection, we applied an observation grill and a questionnaire to the service nursing team. After analysis of the obtained data we substantiated our initial perspective that nurses sometimes didn’t wear the PPE nor used it in the proper way, enhancing the Health Care Associated Infection (HCAI). The HCAI constitutes a health problem due to the high morbility and mortality and the use of PPE is an integrant part of the basic precautions guaranteeing the professionals and the clients’ safety (Pina et al, 2010). So we proposed to spread good practices in the use of PPE developing activities like formation/training of the nurses in the use of PPE, updating the Selection of PPE General Proceeding and elaboration of auditing instruments to the practices.
After detecting the necessities trough non structed interviews with the nursing team and observation in practice, we developed a CAP. We prepared a proceeding about nursing cares to the endotracheal intubation and a compatibilities table of drugs administrated intravenously and developed strategies related with clients’ evacuation of the GUS.

Full textAbstract:
An assemblage of prehistoric Huron chipped stone tools has been analyzed in terms of its inherently dynamic properties. It is hypothesized that the series of measurements and ratios that has been developed is more efficient than existing systems for gauging the changing nature of these implements over time. The statistical evaluation of the data revealed strong linear relationships between various pairs of variables, such as projectile point length and tip angle and end scraper bit edge angles and bit height. It was found that comparing these data to other attributes of these tools, such as use-wear traces and reduction techniques, can be very informative about how each category of tools changed through manufacture, use, and maintenance. The results of this analysis were then compared to those of a more traditional study of a contemporaneous collection of Huron stone tools (Poulton, 1985), demonstrating the utility of the techniques developed.
