Full textAbstract:
Mobile applications can be developed using a variety of different techniques and technologies. One of the most recent of these techniques is the Progressive Web Application (PWA), a cross-platform solution that is built exclusively using common web technologies. The technique has great potential to become a major competitor to native applications but is currently held back by a few rather significant limitations. This project was initiated because of a significant lack of academic research on the topic of PWA, and a perceived poor level of knowledge in the industry about the technique. The goal of the project was to determine if PWA deserved broader utilization or if the current low level of adoption was justified. During the project, two surveys were conducted. The first survey asked mobile application developers from companies in different countries about things such as their knowledge of, experience with, and opinions of PWA. The second survey asked similar questions but was instead answered by lecturers in higher education in Sweden only. The results of this project show that the average level of knowledge of PWAis very low and that developers’ opinions of the technique are quite negative. The limitations of PWA were found to be few but crippling to its potential to achieve widespread adoption.

Full textAbstract:
The main aim of the thesis is to compare two web development technologies. For this purpose, a real estate application is developed using Active Server Pages (ASP.NET) with C-Sharp (C#) and Hypertext Preprocessor (PHP) as languages. The platforms used are Microsoft Visual Studio 2010 for ASP.NET and Eclipse Helios 2010 for PHP developers. Two different servers implemented in these platforms comprising the Sql server 2008 for ASP.NET and MySQL for PHP. A real estate web application is developed with three main panels which are the user panel, advertiser panel and admin panel. The same functional requirements are used in two web technologies. When comparing two technologies, ASP. NET is found to be more efficient and reliable than PHP. During the development process it was found that, PHP is a simple scripting language in comparison to the .NET language C#. However, ASP.NET provides built in tools, function and controls which helps in faster development of code as compared to PHP.

Faradi, Tarik. "Conception d’un système antennaire multi-standard multi-applications dédié au module TRAXBOX pour le suivi de conteneurs." Thesis, Nice, 2016. http://www.theses.fr/2016NICE4023.
Full textAbstract:
Ce mémoire présente la conception de différents systèmes antennaires miniatures devant fonctionner dans des conditions environnementales et climatiques sévères, mais également capables d’opérer dans plusieurs bandes de fréquence ISM et plusieurs standards de communications mobiles. Ce système antennaire dédié infine à l’intégration dans les modules TRAX-BOX développés par la société TRAXENS, doit satisfaire différents critères techniques, industriels et économiques, définis par leur application finale qui est le suivi de conteneurs métalliques multimodaux de grandes dimensions. Pour cela, le système doit présenter un fonctionnement multibande et large bande, un diagramme de rayonnement omnidirectionnel, une bonne efficacité, un encombrement réduit permettant une intégration simple et efficace dans son boîtier, une rigidité mécanique permettant au système d’être protégé contre les vibrations et les chocs, une large plage de températures de fonctionnement et un faible coût de fabrication. Ces exigences techniques et industrielles sont souvent difficiles à satisfaire simultanément. Pour ce faire, plusieurs techniques de conception de systèmes multi-antennaires multibandes ont été employées. L’insertion de fentes sur les résonateurs et la juxtaposition d’éléments parasites a tout d’abord permis d’élargir la bande des antennes. En ce qui concerne l’isolation mutuelle des antennes, l’insertion de fentes sur le plan de masse, est l’une des techniques qui permettent d’isoler les antennesThis thesis presents the design of different small antenna systems, operating in harsh environmental and climatic conditions, but also be able to operate in several ISM frequency bands and several mobile communication standards. This antenna system designed to be integrated in the TRAXBOX modules developed by TRAXENS, must meet various technical, industrial and economic criteria, defined by their final application which is the monitoring of multimodal metallic containers. To this end, the system must provide a multiband and wideband operations, an omnidirectional radiation pattern, a good efficiency, a reduced size allowing an easy and efficient integration into its housing, mechanical rigidity allowing the system to be protected against vibrations and shocks, a wide operating temperature range and low manufacturing cost. These technical and manufacturing requirements are often difficult to simultaneously satisfy. To do this, several design techniques of multiband multi-antenna systems have been employed. The use of slots and parasitic elements has first allowed widening the antennas bands. Regarding the mutual isolation of the antennas, the insertion of slots on the ground plane is one of the techniques that improve the antennas isolation. However, in this manuscript, we have mainly focused on the optimal layout of the parasitic resonators to simultaneously increase the bandwidth but also optimize the system efficiency and the isolation between antennas after interpretation of the various physical phenomena observed

Small unmanned aircraft systems (sUAS) have been in commercial use since the1980’s and over 8-12% of its current uses are in the agricultural sector, but only involving limited uses like surveying, mapping and imaging, which is expected to increase to 47% according to AUVSI with the association of Artificial Intelligence over the next decade. Our research is one such effort to help farmers utilize advanced sUAS technology coupled with Artificial Intelligence and give them meaningful results in a widely used and user friendly interface, like a mobile application. The vision for this application is to provide a completely automated experience to the farmer for a repetitive and periodic analysis of his/her crops where all the instruction needed from the farmer is a push of a button on a one time configured application and ultimately providing results in seconds. This would help the farmer scout their crops, assess yield potential, and determine if additional inputs are needed for increasing grain yield and profit per acre. For making this application we focused on user-friendliness by abstracting crop algorithms, minimized necessary user inputs, and automate the construction of flight paths. Due to internet connection not always being available at farm fields, processing was kept to on-board compute systems and the mobile device to give live results to farmers without reliance on cloud-based analytics. The application is configured to work with DJI Aircraft using OpenCv for video processing and mobile vision, GIS and GPS data for accurate mapping, locating device, sUAS on the mobile application, and FFMPEG for encoding and decoding compressed video data. An algorithm developed by Precision-Ag Lab at the K-State Agronomy Department was implemented into the sUAS application for providing real time yield estimations and nitrogen recommendation algorithm for winter wheat.

Full textAbstract:
Web applications have come a long way both in terms of adoption to provide information and services and in terms of the technologies to develop them. With the emergence of richer and more advanced technologies such as Ajax, web applications have become more interactive, responsive and user friendly. These applications, often called Rich Internet Applications (RIAs) changed the traditional web applications in two primary ways: Dynamic manipulation of client side state and Asynchronous communication with the server. At the same time, such techniques also introduce new challenges. Among these challenges, an important one is the difficulty of automatically crawling these new applications. Crawling is not only important for indexing the contents but also critical to web application assessment such as testing for security vulnerabilities or accessibility. Traditional crawlers are no longer sufficient for these newer technologies and crawling in RIAs is either inexistent or far from perfect. There is a need for an efficient crawler for web applications developed using these new technologies. Further, as more and more enterprises use these new technologies to provide their services, the requirement for a better crawler becomes inevitable. This thesis studies the problems associated with crawling RIAs. Crawling RIAs is fundamentally more difficult than crawling traditional multi-page web applications. The thesis also presents an efficient RIA crawling strategy and compares it with existing methods.

Full textAbstract:
Software patterns have been proven as a valuable way to storing a repeatable solution to a commonly occurring problem in software design. A pattern is not a finished design that can be directly formed into program code; instead it is a description how to solve a problem that may occur in many situations.
In the ontology community very little research have been made in producing high-level patterns where the solution shows how an architecture of an ontology based software might look like.
In this thesis the results of examining how high-level patterns of this type relates to other types of patterns are given and how these patterns would be described are formulated.

Full textAbstract:
The objective of this research is to analyze how the demographic characteristics and reported home locations of Cycle Atlanta smartphone app users compare to those of cyclists reflected by other datasets. The findings of this research show that the majority of Cycle Atlanta users are young, white males belonging to either a very high annual income group or a low annual income group, with fewer users belonging to middle-income groups. Most of the app's users live in east-side, ``intown' Atlanta neighborhoods. Other cyclist data for the Atlanta area show similar trends, although less pronounced than the trends exhibited by Cycle Atlanta users. Because smartphone apps such as Cycle Atlanta are a fairly recent innovation, there is still a great deal of uncertainty as to how equitably they can gather bicycle data. The research presented in this thesis has the potential to empower transportation planners to plan bicycle facilities that will benefit many different facets of the cycling community in Atlanta. This has the potential to increase the mode share of cycling in cities, which will reduce congestion and promote healthier lifestyles.

Abstract
Data mining is a relatively new field of research whose major objective is to acquire knowledge from large amounts of data. In medical and health care areas, due to regulations and due to the availability of computers, a large amount of data is becoming available. On the one hand, practitioners are expected to use all this data in their work but, at the same time, such a large amount of data cannot be processed by humans in a short time to make diagnosis, prognosis and treatment schedules. A major objective of this thesis is to evaluate data mining tools in medical and health care applications to develop a tool that can help make timely and accurate decisions.
Two medical databases are considered, one for describing the various tools and the other as the case study. The first database is related to breast cancer and the second is related to the minimum data set for mental health (MDS-MH). The breast cancer database consists of 10 attributes and the MDS-MH dataset consists of 455 attributes.
As there are a number of data mining algorithms and tools available we consider only a few tools to evaluate on these applications and develop classification rules that can be used in prediction. Our results indicate that for the major case study, namely the mental health problem, over 70 to 80% accurate results are possible.
A further extension of this work is to make available classification rules in mobile devices such as PDAs. Patient information is directly inputted onto the PDA and the classification of these inputted values takes place based on the rules stored on the PDA to provide real time assistance to practitioners.

Full textAbstract:
The concept of Application modeling is a basic and essential component to the design and development of any computer-based application. Application modeling ensures that an application is developed to meet standards that have been set for level of Performance, Maintainability, Scalability, Reliability and Security. Application modeling is not restricted to only large-scale enterprise applications. Its scope covers a range of all applications from single user simple spreadsheet applications to Large Scale Web Applications that are accessed by millions of users at the same time all over the World by using the World Wide Web.Application modeling is mostly a subject that is totally ignored or not used to an extent that its benefits are realized and hence it is often overlooked after the first few weeks or totally confined to a very small subset of the whole application. This can have very drastic effects to the overall design and effectiveness of the application once it is put into production.Different types of Applications have been developed over the passage of time starting off with the large-scale applications, which ran on large Main Frame computers to applications designed to run on dumb terminals systems. Later, a new trend was born with the arrival of the Personal Computer and a new era was seen in computing.The Desktop Enterprise application has been a very common type of application, which covers the aspect of thick clients installed on various user terminals all communicating with a central database via some fast connection Link. These applications have been in use for many years now. However, the latest trend, which has been seen is the development of Web Applications. These are applications that are not restricted to a certain geographical area but are available to the whole world if needed. Of course, these applications can be restricted in access if required and only be run and used within an organization on an Intranet or be restricted to a certain number of organizations running on an extranet. But, whatever the case the scope and range of web applications is certainly much more than any other typical applications, which have been developed in the past.As we have seen above, Web Applications are the most common applications in development these days and even after the fall of the “dot com” era their utility and demand keeps on growing. Due to these factors my dissertation will concentrate on this type of application.As we have already discussed, Application modeling is crucial to the design and development of any application. But when we come to Web Applications, especially ones that will be running on the World Wide Web, it becomes even more crucial because the range of users can grow from a few hundred to millions in a very small space of time. Hence, modeling the application to meet the required needs of Performance, Reliability, Scalability, Maintainability and Security become even more crucial. Another factor, which is as much important as the above five mentioned factors, is the Usability or User experience. The first five factors mentioned above will not be of much use if the user of a particular application cannot easily find the information he or she is looking for or cannot easily complete the task he or she wants to perform. Hence, modeling an application from the point of view of these six factors, is very crucial to the success of any application, especially web based applications. Throughout my dissertation I will be looking at the various factors of Application modeling with reference to Web Applications, mainly the web applications designed for world wide web users as these exhibit the most crucial requirements of an efficient modeling solution. Why I call this dissertation “Enhanced Application modeling techniques for Web Applications” is because I will move ahead of the standard and conventional modeling technique used today where only certain subsets of an application, mainly the middle and data tier, are clearly modeled. I will try to engulf the whole application with special emphasis on the presentation tier and model it to meet the requirements, which are defined as the ultimate goal to be achieved by the end product. I will also highlight the benefits that are achieved by modeling each of the three tiers of the web application as compared to the traditional method of modeling only two tiers of the same application.

Full textAbstract:
L'omniprésence des applications Web, la possession et l'utilisation simultanée de plusieurs appareils par un seul utilisateur sont les principaux facteurs de la demande accrue pour les applications multi-écrans. La création des applications multi-écrans imposent des défis sur le développeur d'applications et sur le designer, en particulier s'ils réutilisent les applications web existantes. Par exemple, les developpeurs doivent planifier la distribution de l'interface utilisateur et ils doivent prendre en compte la diversité des dispositifs pour mieux présenter le contenu. En plus, ils doivent re-penser l'organisation du code de l'application afin de préserver la fonctionnalité de l'application et surtout assurer la communication entre les parties distribuées de l'application. Dans ce travail, nous proposons un système de bout en bout pour le refactoring des applications web. Le système permet la réutilisation des applications existante, mono-écran, pour créer automatiquement des applications multi-écrans. Les parties distribuées des applications générées ont leur mise en page adaptée aux petits et grands dispositifs et ils sont prêts â fonctionner de manière synchrone tout en fournissant des tâches complémentaires. La performance du système est évaluée quantitativement sur un ensemble d'applications contenant au moins un élément vidéo et du contenu interactifThe ubiquity of web applications and the user possession and utilization of multiple devices are major factors for the increased demand for multi-screen applications. Multi-screen applications impose challenges on the application developer and designer especially if existing single-screen applications have to be transformed to the multiscreen environment. Designers should plan the user interface distribution and should adapt the layout for various devices. Developers should re-organize the application logic and associate it to the distributed user interface. They should preserve the application functionality and finally they need to adapt it to the underlying multiscreen platform. In this work, we propose an end-to-end refactoring system. The system allows the re-use of existing single-screen applications to automatically create multi-screen applications. The components of the multi-screen applications have their layout adapted to small and large device and they are ready to operate synchronously to provide a complementary usage experience. Our system is quantitatively evaluated on different sets of applications containing at least one video element and interactive content. The content division of our system corresponds to a ground truth division with an average recall of 0.84. In addition, our layout refactoring approach obtains 60% accuracy on the tested applications. In addition, we evaluate the performance of the run-time behavior of one application and we compute the delays that are caused by our system and by the network in a real physical environment: with a total delay of 5 ms, our solution is realistic

Full textAbstract:
Image enhancement improves an image appearance by increasing dominance of some features or by decreasing ambiguity between different regions of the image. Image enhancement techniques have been widely used in many applications of image processing where the subjective quality of images is important for human interpretation. In many cases, the images have lack of clarity and have some effects on images due to fog, low light and other daylight effects exist. So, the images which have these scenarios should be enhanced and made clear to recognize the objects clearly. Histogram-based image enhancement technique is mainly based on equalizing the histogram of the image and increasing the dynamic range corresponding to the image. The Histogram equalization algorithm was performed and tested using different images facing the low light, fog images and colour contrast and succeeded in obtaining enhanced images. This technique is implemented by averaging the histogram values as the probability density function. Initially, we have worked with the MATLAB code on Histogram Equalization and made changes to implement an Application Program Interface i.e., API using Xamarin software. The mobile application developed using Xamarin software works efficiently and has less execution time when compared to the application developed in Android Studio. Debugging of the application is successfully done in both Android and IOS versions. The focus of this thesis is to develop a mobile application on Image enhancement using Xamarin on low light, foggy images.

Full textAbstract:
Aromatic and aliphatic diacid chlorides were used to condense naturally occurring diamino acids and their esterified derivatives. It was anticipated the resulting functional polyamides would biodegrade to physiologically acceptable compounds and show pH dependant solubility could be used for biomedical applications ranging from enteric coatings to hydrosoluble drug delivery vehicles capable of targeting areas of low physiological pH. With these applications in mind the polymers were characterised by infra red spectroscopy, gel permeation chromatography and in the case of aqueous soluble polymers by potentiometric titration. Thin films of poly (lysine ethyl ester isophthalamide) plasticised with poly (caprolactone) were cast from DMSO/chloroform solutions and their mechanical properties measured on a Hounsfield Hti tensiometer. Interfacial synthesis was investigated as a synthetic route for the production of linear functional polyamides. High molecular weight polymer was obtained only when esterified diamino acids were condensed with aromatic diacid chlorides. The method was unsuitable for the production of copolymers of free and esterified amino acids with a diacid chloride. A novel miscible mixed solvent single phase reaction was investigated for production of copolymers of esterified and non-esterified amino acids with diacid chlorides. Aliphatic diacid chlorides were unsuitable for condensing diamino acids using this technique because of high rates of hydrolysis. The technique gave high molecular weight homopolymers from esterified diamino acids and aromatic diacid chlorides.

Full textAbstract:
Enterprise systems and applications are getting more and more complex. In 30 years computing has transformed from big single machines to highly heterogeneous systems. Businesses are today depending on a super-sized mixed bag of applications that have been introduced over the years. Businesses have much to gain by obtaining a holistic view of their data and integrating business processes that are spread over different systems. This master of thesis explores critical success factors (CSF) for enterprise application integration (EAI) from the perspective of developing new application into such environment. Based on current research in the field of EAI, and experiences gained from a real-life scenario the report argues for the importance of integration and what the most influential factors for success are. Among many significantly important factors, two main trends emerge as especially important: developer guidance and documentation, and integration functionality. The former leads to success by focusing on developer productivity through the use scorecards, principles and guidance, well-specified interfaces, and skilled EAI employees; and the latter by extending integration functionality to include many-tomany integration strategies and workflows to model the business.

The number of applications for the Android platform found on Google Play is now over 1 million and there are over 1.5 billion downloads each month . With a low cost of entry the Android platform attracts developers many of which do not have the necessary competence or experience to develop secure applications. Weassess 20 Android applications using a custom testing methodology based on the OWASP Mobile Project and look for common vulnerabilities. We decompileapplications using Dare and review the source codemanually as well as using static and dynamic analysis to look for vulnerabilities.We also evaluate existing vulnerability classifications and argue which onesare most fitting to apply to Android vulnerabilities for educational and research purposes. We then categorize our findings according to OWASP MobileTop 10 and present mitigation strategies for each category as a whole. Finally,we argue the implications of the vulnerabilities to end-users.

Full textAbstract:
Mobile applications provide services that can benefit various sectors of the society. It is imperative that the realization of mobile applications be well-planned and based on standards. The interplay of Extensible Markup Language (XML)-based technologies, software engineering principles, and "best practices" formalized as patterns provides such a systematic approach. This thesis formulates a rigorous classification of mobile application patterns into four categories: architecture, process, product, and usage. To express the patterns in a universal manner, an XML-based pattern notation, the Mobile Application Patterns Markup Language (MAPML), is introduced. Based on a requirements analysis and design description, the specification of MAPML is given. MAPML is equipped with a collection of tools that includes formal grammars for MAPML, and solutions for authoring, processing, and presenting MAPML documents on the Web. The thesis concludes with a discussion of the current state of work and directions for future improvement.

Full textAbstract:
This thesis presents the design, analysis and optimization of a MEMS capacitive temperature sensor. The capacitive sensors are utilized in a wide range of applications from industrial and automotive applications to biomedical and food processing. A capacitive sensor has two conductive electrodes and its working principle depends on the change in the position of the electrodes or their effective area, which ultimately results in a change in the capacitance of the device. This thesis describes the modeling and the simulation results of a capacitive temperature sensor with a set of bimorph beams working as thermal actuators. The thermal actuator creates out-of-plane displacements and changes the distance between the electrodes as the ambient temperature changes. The presented bimorph capacitive temperature sensor consists of two bilayer silicon-gold beams and two capacitive electrodes, one of them is fixed to the substrate and the second one is connected to the beams. Different beam sizes and electrode shapes are designed and simulated and the characteristics capacitance-temperature (C-T) response of the sensor is obtained. The goal of this work is to modify and optimize the sensor geometry such that the C-T response is more linear, providing nearly constant sensitivity. ANSYS mechanical APDL is used as the finite element software for simulation and optimization of the sensor design, and coupled-field multiphysics solver is utilized to solve the electrostatic and structural domains. The simulation results show that for a given fabrication process, where the thickness of the structural and sacrificial layers in fabrication process is fixed, it is possible to modify the dimensions and geometry of the sensor such that a C-T response with high linearity is obtained.

Full textAbstract:
Novel glass tracers, organic and inorganic polymers based on narrow band atomic fluorescence, have been developed for deployment as environmental tracers. The use of discrete fluorescent species in an environmentally stable host has been investigated to replace existing toxic, broad band molecular dye tracers. The narrow band emission signals offer the potential for the tracing of a large numbers of signals in the same environment; this has been investigated by examining multiple doped tracers which have the potential for coding to specific effluent sources or particulates. The concept of using lanthanide doped glasses as environmental tracers has been demonstrated. The spectral characterisation and concentration studies of the lanthanide doped tracer allow the selection of parameters to produce future tracers and detection systems for particular applications. Therefore by altering the chosen lanthanide dopant, number of dopants, dopant concentration and using selective excitation and emission wavelengths there are a huge number of possible unique tracer combinations. The significantly narrower bandwidth emission peaks of the lanthanide based tracers achieve more selective detection of multiple tracers without overlap interference and gives the potential to selectively and simultaneously monitor many different tracers in the same location. The spectral lifetime characteristics of the lanthanide tracers are very different from the lifetime of background fluorescence which is typically molecular in origin. This is an extra discrimination against background interference and is an important additional advantage of using lanthanide based tracers. Overall this work shows that a very large number of unique environmental tracers can be obtained by varying the concentration, the number of lanthanide ions in a glass and also the possibility of using organic and inorganic lanthanide chelate doped tracers.

Full textAbstract:
Next space missions should rely on the DTN architecture and its associated Bundle Protocol (BP) to cope with the challenges faced by interplanetary links, such as long delays and disruption. This has led to new BP implementations or new releases, incorporating version 7, recently standardized by IETF. Although positive per se, this has exacerbated an already existing fragmentation problem, as every implementation has its own API and its own set of bundle options supported, which is a significant obstacle to the development of third party applications.
To alleviate this problem, a new “abstracted” API for bundle protocol applications, called Unified API, has been developed during this thesis, and it is presented here.
The Unified API is a complete refactoring of the old “Abstraction Layer”. As the predecessor it aims to decouple a DTN application from the BP implementations, with great advantages in terms of portability, maintenance and interoperability. However, the Unified API is more ambitious and it has the goal to present also a new API, now much closer to the familiar UDP socket and, more generally, to facilitate the development of new DTN applications as much as possible.
To obtain this, the whole structure has been organized in three layers, of which only the top one is seen by applications. This layer consists of four blocks, of which the most important is the “Socket” block. The other blocks provide the programmer with high-level tools to create and modify a bundle, to parse the input string, to implement conditional prints etc.
The Unified API is compatible with most BP implementations (DTN2/DTNME, ION, IBR-DTN, µD3TN). As them, it is released as free software and it is going to replace its predecessors in the next release of the DTNsuite, the Unibo collection of DTN applications included in ION, the DTN implementation by NASA JPL.
The hope is that the Unified API will encourage third-party programmers, thus contributing to the success of DTN networking.

Previous issue date: 2015The rise of Internet of Things sensors, social networking and mobile devices has led to an explosion of available data. Gaining insights into this data has led to the area of Big Data analytics. The MapReduce (MR) framework, as implemented in Hadoop, has become the de facto standard for Big Data analytics. It also forms a base platform for a plurality of Big Data technologies that are used today. To handle the ever-increasing data size, Hadoop is a scalable framework that allows dedicated, seemingly unbound numbers of servers to participate in the analytics process. Response time of an analytics request is an important factor for time to value/insights. While the compute and disk I/O requirements can be scaled with the number of servers, scaling the system leads to increased network traffic. Arguably, the communication-heavy phase of MR contributes significantly to the overall response time. This problem is further aggravated, if communication patterns are heavily skewed, as is not uncommon in many MR workloads. MR applications normally run in large data centers (DCs) employing dense network topologies (e. g. multi-rooted trees) with multiple paths available between any pair of hosts. These DC network designs, combined with recent software-defined network (SDN) programmability, offer a new opportunity to dynamically and intelligently configure the network to achieve shorter application runtime. The initial intuition motivating our work is that the well-defined structure of MR and the rich traffic demand information available in Hadoop’s log and meta-data files could be used to guide the network control. We therefore conjecture that an application-aware network control (i. e., one that knows the applicationlevel semantics and traffic demands) can improve MR applications’ performance when compared to state-of-the-art application-agnostic network control. To confirm our thesis, we first studied MR systems in detail and identified typical communication patterns and common causes of network-related performance bottlenecks in MR applications. Then, we studied the state of the art in DC networks and evaluated its ability to handle MapReduce-like communication patterns. Our results confirmed the assumption that existing techniques are not able to deal with MR communication patterns mainly because of the lack of visibility of application-level information. Based on these findings, we proposed an architecture for an application-aware network control for DCs running MR applications. We implemented a prototype within a SDN controller and used it to successfully accelerate MR applications. Depending on the network oversubscription ratio, we demonstrated a 2% to 58% reduction in the job completion time for popular MR benchmarks, when compared to ECMP (the de facto flow allocation algorithm in multipath DC networks), thus, confirming the thesis. Other contributions include a method to predict network demands in MR applications, algorithms to identify the critical communication path in MR shuffle and dynamically alocate paths to flows in a multipath network, and an emulation-based testbed for realistic MR workloads.
O modelo de programação MapReduce (MR), tal como implementado por Hadoop, tornou-se o padrão de facto para análise de dados de larga escala em data centers, sendo também a base para uma grande variedade de tecnologias de Big Data que são utilizadas atualmente. Neste contexto, Hadoop é um framework escalável que permite a utilização de um grande número de servidores para manipular os crescentes conjutos de dados da área de Big Data. Enquanto capacidade de processamento e E/S podem ser escalados através da adição de mais servidores, isto gera um tráfego acentuado na rede. No caso de MR, a fase que realiza comunicações via rede representa uma significante parcela do tempo total de execução. Esse problema é agravado ainda mais quando os padrões de comunicação são desbalanceados, o que não é incomum para muitas aplicações MR. MR normalmente executa em grandes data centers (DC) de commodity hardware. A rede de tais DCs normalmente utiliza topologias densas que oferecem múltiplos caminhos alternativos (multipath) entre cada par de hosts. Este tipo de topologia, combinado com a emergente tecnologia de redes definidas por software (SDN), possibilita a criação de protocolos inteligentes para distribuir o tráfego entre os diferentes caminhos disponíveis e reduzir o tempo de execução das aplicações. Assim, esse trabalho propõe a criação de um controle de rede ciente de aplicação (isto é, que conhece as semânticas e demandas de tráfego do nível de aplicação) para melhorar o desempenho de aplicações MR quando comparado com um controle de rede tradicional. Para isso, primeiramente estudou-se MR em detalhes e identificou-se os padrões típicos de comunicação e causas frequentes de gargalos de desempenho relativos à utilização de rede nesse tipo de aplicação. Em seguida, estudou-se o estado da arte em redes de data centers e sua habilidade de lidar com os padrões de comunicação encontrados em aplicações MR. Baseado nos resultados obtidos, foi proposta uma arquitetura para controle de rede ciente de aplicação. Um protótipo foi desenvolvido utilizando um controlador SDN, o qual foi utilizado com sucesso para acelerar aplicações MR. Experimentos utilizando benchmarks populares e diferentes características de rede demonstraram uma redução de 2% a 58% no tempo total de execução de aplicações MR. Além do ganho de desempenho em aplicações MR, outras contribuições desse trabalho incluem um método para predizer demandas de tráfego de aplicações MR, heurísticas para otimização de rede e um ambiente de testes para redes de data centers baseado em emulação.

Full textAbstract:
This master thesis investigates studies on fashion oriented people according to the "Outfit-Centric Accessories" concept. The outfit-centric accessories concept originated from recent research study by Juhlin and Zhang (2011) about mobile phone representation in fashion and Aesthetic of Interaction area of Human-Computer Interaction (HCI). The term outfit-centric accessories originated from clothing and wearer. In this concept an outfit is playing a role as the centerpiece and a mobile phone is functioning as a sort of an accessory that can be added to an outfit. The main aim here is to explore design solution for matching the visual appearance of mobile device with different outfit of a person. The first phase of this thesis is based on a research conducted through a literature review on the Aesthetic Interaction and the Experience-Centered design approach. Literature study has been followed by studies the relation between the fashion and technology and the outfit-centric accessories concept precisely. The findings that are presented here are based on field studies on fashion oriented people who are interested in mobile phone design. Filed studies were conducted through gathering input entries from social networking services such as Facebook and Blogger, survey of questionnaire on outfit matching mechanism, and inquiring people around. The findings are described the outfit "Match Mechanism" and the "social activities around the outfit matching" in relation to the concept. These descriptions have led the project to the system design and development phase regarding the outfit-centric accessories concept. This phase resulted in the Android based mobile application named "Mobile Fashion". This application enables a user to match a mobile device with variety of clothing in the form of a background image, cover, or printable sticker (skin phone) and it allows a user to participate in social services by sharing the look with others. It is worth mentioning that "Mobile Fashion" application presented in Vinnova-nytt (June 2011, No.3, p15) and International Joint Conference on Ambient Intelligent (AmI'11 November, 16, 2011, Amsterdam) (see appendix 14 and 15).

Full textAbstract:
I ett IMS-nät (IP Multimedia Subsystem) finns Applikations Servrar (AS) som tillhandahåller tjänster, dessa AS är ofta SIP-servrar (Session Initation Protocol).
Målet för det här examensarbetet var att finna den SIP-server som är mest lämpad att använda när man ska lägga till en tjänst i ett IMS-nät.
Först gjordes en undersökning av tillgängliga SIP AS och ett tiotal hittades. Några av dem valdes ut för att jämföras och utredas mer noggrant. Inledningsvis inspekterades deras dokumentation, sedan analyserades proceduren att installera AS och att lägga till en tjänst på dem. Till sist lades tjänsten till i ett IMS-nät.
Eftersom varken deras fördelar eller nackdelar utmärkte sig på ett sådant sett att någon av dem sammantaget var bättre än den andra, kunde tyvärr inte någon av dem pekas ut som den mest lämpade.
In an IMS (IP Multimedia Subsystem) network there are Application Servers (ASs) which host and execute services. These are often SIP (Session Initiation Protocol) servers. The goal for this thesis was to evaluate a selection of open source SIP ASs to see which one was most suited for IMS service development.
Ten different SIP ASs was found in an initial search. They were briefly reviewed and some of them were chosen as candidates for further investigation.
The documentation of the chosen servers were thoroughly explored and evaluated; as was the installation process and how to deploy a service to them.
Finally the servers were installed and a service was implemented and deployed to an IMS network.
Unfortunately, I could not point out one of the ASs to be more suited than another for deploying an IMS service on. This was because they had different pros and cons and none of them were distinguishing in a way that made them superior to the other.

The smartwatch has been predicted to be the next big thing in the ecosystem of wearable and mobile devices. The success of the smartphone has a lot to do with the support from third party developers and their applications. This support will most likely be of utmost importance if the smartwatch is going to be successful. But what are suitable applications for this type of device? What are people's expectations and opinions on smartwatches? This thesis work delved into these matters with focus on development for the Apple Watch. This was done through an online survey that reached more than 1400 people, through a field study for one person that used the smartwatch as an air-travel tool and finally through a usability test conducted on five people that tried out several applications, most of which were developed for this project. Four different applications were implemented: a timetable application, a museum audio-guide, a game and an airline application. The results indicate that people generally expected the smartwatch to act as an extension for their smartphones and notifications seemed to be an area in which the smartwatch excelled. The results also show that there are many applicable areas the smartwatch can be used for, but that interaction with these should be kept quick and simple. This is extra important given the limited screen-size and special considerations should be taken on what content to display.Smarta klockor har länge framstått som nästa stora insteg inom ekosystemet av mobila enheter. Succén bakom smarttelefoner har mycket att göra med det stora stödet från tredjepartsutvecklare och deras applikationer. För att smarta klockor ska nå liknande nivåer är det troligt att detta tredjepartsstöd är av stor betydelse. Men vad är lämpliga applikationer för detta format? Vad har folk för förväntningar på denna plattform? Det här arbetet har handlat om dessa ämnen med fokus på utveckling mot Apple Watch. Arbetet har gjorts genom en enkätundersökning online som nått över 1400 användare, genom en fältstudie på en person där en applikation för flygresor testats samt genom ett användartest på fem personer där dessa fått testa på ett antal applikationer för Apple Watch, varav de flesta av dessa var utvecklade för detta projekt. Totalt implementerades fyra applikationer: en tidtabellsapplikation för kommunaltrafik, en ljudguide för ett museum, ett spel och en applikation för flygresande. Resultaten visar att folk verkar förvänta sig att en smart klocka ska fungera som en förlängning av deras smarttelefon och det verkar som att notifikationer är ett väldigt bra användningsområde för formatet. Resultaten visar också att det verkar finnas många olika användningsområden för smarta klockor men att interaktioner med dessa bör vara korta och lätthanterliga. Detta är extra viktigt givet den begränsade skärmstorleken och man bör noga överväga hur och vad man presenterar för användaren.

Full textAbstract:
L’analyse de flux d’évènements pour reconnaître des comportements complexes prédéfinis (Complex Event Processing – CEP) permet d’interpréter et de réagir à des quantités importantes de données ne pouvant être appréhendées telles quelles. Dans cette thèse, nous fournissons le cadre théorique général d’un CEP en adoptant une approche purement formelle qui assure une possibilité de vérification et d’analyse du processus de reconnaissance. Nous définissons un langage, le langage des chroniques, permettant de décrire les comportements complexes à reconnaître. Nous formalisons la notion de reconnaissance de chronique à l’aide d’une sémantique ensembliste fondée sur une représentation arborescente des reconnaissances. Dans une visée applicative, nous développons ensuite deux modèles du processus de reconnaissance. Le premier est réalisé avec le formalisme des réseaux de Petri colorés et permet de valider les principes de reconnaissance en faisant notamment ressortir les problèmes de concurrence et de modularité. Le second implémente directement le formalisme mathématique sous la forme d’une bibliothèque C++ appelée Chronicle Recognition Library (CRL) et disponible en open source. Nous tirons parti de cette implémentation pour traiter deux cas d’applications liés à l’insertion des drones dans l’espace aérien. La première vise à surveiller la cohérence d’un système de drones insérés dans le trafic aérien, en cas de pannes de liens de communication. Notre application permet d’une part de vérifier la cohérence des procédures actuellement mises en place en cas de pannes ; et d’autre part de compléter ces procédures par des alarmes dans les situations inévitables causées par des erreurs humaines. La seconde application surveille le bon respect des procédures de sécurité d’un drone partant en mission et traversant diverses zones, contrôlées ou non, de l’espace aérienRecognising complex predefined behaviours by the analysis of event flows (Complex Event Processing - CEP) alows to interpret and react to large quantities of data wich one would not be able to apprehend alone. In this Ph.D. thesis, we provide a general theoretical framework for CEP through a purely formal approach ensuring the possibility to check and analyse the recognition process. We define a language, the chronicle language, allowing the description of the complex behaviours to be recognised. We formalise the notion of chronicle recognition through a set semantics based on an arborescent representation of recognitions. In order to use this framework, we then develop two models of the recognition process. The first relies on coloured Petri nets and allows the validation of recognition principles including concurrency and modularity issues. The second model directly implements the mathematical formalism in a C++ library, chronicle recognition library (CRL), wich is avaible in open source. We use this implementation to fulfil two applications linked to the insertion of unmanned aircraft system inside air traffic in case of communication link breakdowns. This application allows, on the other hand, to check the consistency of the procedures currently followed in case of failures ; and, on the other hand, to complete these procedures with alarms in case of unavoidable situations caused by human errors. The second application oversees that the security procedures of an unmanned aircraft flying through controlled or uncontrolled airspace are correctly followed

Le travail présenté dans cette thèse concerne l'analyticité et l'algébricité d'applications de Cauchy-Riemann (CR) lisse entre variétés CR analytiques ou algébriques réelles. Ce sujet a trait aux propriétés de prolongement d'applications et a récemment connu un regain d'activité. Notre contribution porte principalement sur l'étude du cas non équidimensionnel et sur le passage à la codimension supérieure à un. Dans la première partie de la thèse, nous considérons la question de l'algébricité d'une application holomorphe locale f envoyant une sous-variété algébrique réelle générique minimale M de Cn, n > 1, dans un sous-ensemble algébrique réel M' de Cn'. Ce problème a pour origine les travaux de Poincaré (1907), et plus récemment de Webster (1977). L'introduction de "variétés caractéristiques" associées à la fois aux ensembles M et M' et à l'application f nous permet de donner deux nouvelles conditions pour que f soit algébrique. Dans la deuxième partie de la thèse, nous étudions le problème de l'analyticité d'une application CR lisse f : M -> M' entre une sous-variété analytique réelle générique minimale M de Cn, n>1, et un sous-ensemble analytique réel M' de Cn'. Nous établissons une généralisation du principe de réflexion de Lewy-Pinchuk (1975-77) et prouvons que si la variété caractéristique est de dimension zéro, f est analytique réelle. Dans la troisième partie de la thèse, nous traitons la situation plus générale où la variété caractéristique est de dimension arbitraire. Nous démontrons que si M' ne contient pas de courbe complexe, f est analytique sur un ouvert dense de M. Plus généralement, nous établissons une estimation supérieure de l'analyticité partielle de f, en fonction de la dimension maximale des feuilletages holomorphes locaux contenus dans M'.

Full textAbstract:
L’adamantane est un hydrocarbure polycyclique, rigide et assez encombrant. En médecine, plusieurs dérivés à base d’adamantane ont été développés notamment comme agent antiviraux. Facilement fonctionnalisés, sa conformation 3D permet d’amoindrir les encombrements stériques entre les différents groupements fonctionnels. Nous avons décidé d’utiliser ses propriétés pour concevoir des structures plus complexes, à savoir, des dendrons et des foldamers. Les dendrons sont des polymères synthétiques possédant des propriétés intéressantes. De par leurs tailles, ils sont considérés comme des nanoparticules et possèdent un ciblage passif des cellules cancéreuses. De plus, facilement fonctionnalisés ils peuvent être utilisés comme molécule cargo dans la vectorisation de principes actifs. Outre la vectorisation, les dendrons permettent d’améliorer les propriétés physico-chimiques d’un médicament (absorption, distribution, métabolisme, élimination et toxicité). Nous avons alors choisi de concevoir des dendrons à base d’adamantane. Ces derniers ont la particularité de ne pas posséder d’espaceur entre les molécules d'adamantane se qui les rend hautement rigides. L’analyse par microscopie électronique à transmission de différents dendrons a permis d’étudier leurs morphologies selon leurs fonctionnalisations ainsi que l’effet du solvant, de la concentration et du support sur leurs auto-assemblages. Dans un second temps, nous avons conçu un acide aminé basé sur l’adamantane. Cet acide g-aminé a ensuite été incorporé dans des séquences peptidiques et les effets de l’adamantane sur la structure secondaire des peptides ont été étudiés par dichroïsme circulaireAdamantane is a polycyclic hydrocarbon, rigid and quite bulky. In medicine, several adamantane-based derivatives have been developed especially as antiviral agents. Easily functionalized, its 3D well-defined structure considerably decrease the sterical hindrance between its different functional groups. In this context, we decided to use adamantane to build more complex structures such as dendrons and foldamers. Dendrons are synthetic polymers with interesting properties. Because of their size, they are considered as nanoparticles and possess a passive cancer cell targeting. In addition,they are easily functionalized and can be use as vector of drugs. Indeed, the dendrons improve the physochemical properties of a drug (absorption, distribution, metabolism, elimination and toxicity). We decided to combine adamantane and dendrons to build adamantane-based dendrons. However, these dendrons have the particularity of not having spacer between the adamantane moieties, thus, they are highly rigid. Transmission electron microscopy analysis of the different functionalized dendrons allowed to study their self-assembly capacity and their morphology according to their functional groups,the solvent, the concentration and the support. In a second step, we designed an amino acid based on adamantane. This g-amino acid has been introduced in a peptide backbone using solid phase peptide synthesis. Then, the effects of adamantane onto peptide secondary structures have been studied by circular dichroism

Full textAbstract:
Actuellement les smartphones possèdent un grand éventail de fonctionnalités. Ces objets tout en un, sont constamment connectés. Il est l'appareil favori plébiscité par les utilisateurs parmi tous les dispositifs de communication existants. Les applications actuelles développées pour les smartphones doivent donc faire face à une forte augmentation de la demande en termes de fonctionnalités tandis que - dans un même temps - les smartphones doivent répondre à des critères de compacité et de conception qui les limitent en énergie et à un environnement d'exécution pauvre en ressources. Utiliser un système riche en ressource est une solution classique introduite en informatique dans les nuages mobiles (Mobile Cloud Computing), celle-ci permet de contourner les limites des appareils mobiles en exécutant à distance, toutes ou certaines parties des applications dans ces environnements de nuage. Certaines architectures émergent, mais peu d'algorithmes existent pour traiter les propriétés dynamiques de ces environnements. Dans cette thèse, nous focalisons notre intérêt sur la conception d'ACOMMA (Ant-inspired Collaborative Offloading Middleware for Mobile Applications), un interlogiciel d'exécution déportée collaborative inspirée par le comportement des fourmis, pour les applications mobiles. C'est une architecture orientée service permettant de décharger dynamiquement des partitions d'applications, de manière simultanée, sur plusieurs clouds éloignés ou sur un cloud local créé spontanément, incluant les appareils du voisinage. Les principales contributions de cette thèse sont doubles. Si beaucoup d'intergiciels traitent un ou plusieurs défis relatifs à l'éxecution déportée, peu proposent une architecture ouverte basée sur des services qui serait facile à utiliser sur n'importe quel support mobile sans aucun exigence particulière. Parmi les principaux défis il y a les questions de quoi et quand décharger dans cet environnement très dynamique. A cette fin, nous développons des algorithmes de prises de décisions bio-inspirées : un processus de prise de décision bi-objectif dynamique avec apprentissage et un processus de prise de décision en collaboration avec les autres dispositifs mobiles du voisinage. Nous définissons un mécanisme de dépôt d'exécution avec une méthode de partitionnement grain fin de son graphe d'appel. Nous utilisons les algorithmes des colonies de fourmis pour optimiser bi-objectivement la consommation du CPU et le temps total d'exécution, en incluant la latence du réseau. Nous montrons que les algorithmes des fourmis sont plus facilement re-adaptables face aux modifications du contexte, peuvent être très efficaces en ajoutant des algorithmes de cache par comparaison de chaîne (string matching caching) et autorisent facilement la dissémination du profil de l'application afin de créer une exécution déportée collaborative dans le voisinageNot bounded by time and place, and having now a wide range of capabilities, smartphones are all-in-one always connected devices - the favorite devices selected by users as the most effective, convenient and neces- sary communication tools. Current applications developed for smartphones have to face a growing demand in functionalities - from users, in data collecting and storage - from IoT device in vicinity, in computing resources - for data analysis and user profiling; while - at the same time - they have to fit into a compact and constrained design, limited energy savings, and a relatively resource-poor execution environment. Using resource- rich systems is the classic solution introduced in Mobile Cloud Computing to overcome these mobile device limitations by remotely executing all or part of applications to cloud environments. The technique is known as application offloading. Offloading to a cloud - implemented as geographically-distant data center - however introduces a great network latency that is not acceptable to smartphone users. Hence, massive offloading to a centralized architecture creates a bottleneck that prevents scalability required by the expanding market of IoT devices. Fog Computing has been introduced to bring back the storage and computation capabilities in the user vicinity or close to a needed location. Some architectures are emerging, but few algorithms exist to deal with the dynamic properties of these environments. In this thesis, we focus our interest on designing ACOMMA, an Ant-inspired Collaborative Offloading Middleware for Mobile Applications that allowing to dynamically offload application partitions - at the same time - to several remote clouds or to spontaneously-created local clouds including devices in the vicinity. The main contributions of this thesis are twofold. If many middlewares dealt with one or more of offloading challenges, few proposed an open architecture based on services which is easy to use for any mobile device without any special requirement. Among the main challenges are the issues of what and when to offload in a dynamically changing environment where mobile device profile, context, and server properties play a considerable role in effectiveness. To this end, we develop bio-inspired decision-making algorithms: a dynamic bi-objective decision-making process with learning, and a decision-making process in collaboration with other mobile devices in the vicinity. We define an offloading mechanism with a fine-grained method-level application partitioning on its call graph. We use ant colony algorithms to optimize bi-objectively the CPU consumption and the total execution time - including the network latency

Full textAbstract:
User development of applications provides end users with an alternative to the traditional process of systems development by allowing them to solve job related problems by developing their own software applications. User developed applications (UDAs) support decision making and organisational processes in the majority of organisations, and the ability to develop small applications forms part of the job requirements for many positions. Despite its pervasiveness, there are many risks associated with user development of applications. These risks result primarily from decreases in application quality that arise when end users have had little training and do not follow system development methodologies.
The primary aim of the research described in this thesis is to gain a better understanding of UDA success. In particular, the thesis considers the role of system quality in UDA success and the ability of end user developers to judge whether the applications they develop will have a positive impact on their performance of tasks. The research also investigates factors that might impact upon this ability.
The research objectives were addressed through two empirical studies. Two possible models of UDA success provided the starting point for Study 1. The first model is DeLone and McLean's (1992) model of IS success, and the second model is a version of this model that was modified to address concerns about the DeLone and McLean model and to reflect current research about UDA success. The models were tested using data from a field study involving business people participating in a business policy simulation, where they developed spreadsheet applications to assist in decision making. Structural equation modelling was used to test the models. Neither of the models was well supported by the data. However, the analysis provided strong support for relationships between perceived system quality and user satisfaction, information quality and user satisfaction, user satisfaction and intended use, and user satisfaction and individual impact. It is notable that the model paths that were supported in Study 1 were primarily those that reflect user perceptions rather than objective measures. This study highlighted that user perceptions of information systems success play a significant role in the UDA domain. The results did, however, suggest that there might be a direct relationship between system quality and individual impact.
Study 2 was a laboratory experiment and the participants were end users from a range of organisations. A revised research model was developed based on the findings of Study 1, and structural equation modelling was again used to test the model. The model paths that were supported suggest that for small to moderate applications, increases in spreadsheet development knowledge lead to increases in system quality and consequently the development of better quality spreadsheets. They also suggest that for these kinds of applications, end users have realistic perceptions of system quality and hence that user satisfaction may be an appropriate measure of UDA success. The results of Study 2 also provided insight into the role of user involvement in end user development, clarifying the process by which benefits are obtained. The study also provided insight into the importance of spreadsheet development knowledge for successful use (as well as development) of a spreadsheet application.
The results described in this thesis have practical implications for the management of user development of applications. They highlight the need either to increase end user levels of development knowledge via training so that end users can cope with applications of greater complexity, or to provide other forms of support for development. The role of organisational standards and guidelines is also be considered in the thesis and it is suggested that there is a particular need for guidelines on what kinds of applications are suitable for end user development.

Full textAbstract:
In this dissertation, I enumerate several privacy problems in online social networks (OSNs) and describe a system called Footlights that addresses them. Footlights is a platform for distributed social applications that allows users to control the sharing of private information. It is designed to compete with the performance of today's centralised OSNs, but it does not trust centralised infrastructure to enforce security properties. Based on several socio-technical scenarios, I extract concrete technical problems to be solved and show how the existing research literature does not solve them. Addressing these problems fully would fundamentally change users' interactions with OSNs, providing real control over online sharing. I also demonstrate that today's OSNs do not provide this control: both user data and the social graph are vulnerable to practical privacy attacks. Footlights' storage substrate provides private, scalable, sharable storage using untrusted servers. Under realistic assumptions, the direct cost of operating this storage system is less than one US dollar per user-year. It is the foundation for a practical shared filesystem, a perfectly unobservable communications channel and a distributed application platform. The Footlights application platform allows third-party developers to write social applications without direct access to users' private data. Applications run in a confined environment with a private-by-default security model: applications can only access user information with explicit user consent. I demonstrate that practical applications can be written on this platform. The security of Footlights user data is based on public-key cryptography, but users are able to log in to the system without carrying a private key on a hardware token. Instead, users authenticate to a set of authentication agents using a weak secret such as a user-chosen password or randomly-assigned 4-digit number. The protocol is designed to be secure even in the face of malicious authentication agents.

Full textAbstract:
In this thesis, the newly released framework Ionic 2, which claims to fix the problems cross platform frameworks has suffered from concerning bad performance and bad user experience, has been evaluated. The study has focused on the Android platform by comparing a native developed application to an Ionic 2 developed application. The comparison has been made on performance and user experience. As an extent, Ionic 2 are also compared to another evaluation study made for React Native, to see how the two frameworks differ, both performance wise and user experience wise. The native application performs better in all performance tests, even though the difference only was a few percent for memory usage and battery consumption. In the user tests, the result was of different nature. Some users did not notice any differences between the applications, whilst some had big concerns with how the application behaved. The overall conclusion is that Ionic still has some way to go to compete with native applications. If considering using Ionic 2, you need to be aware of the flaws it has. From the data gathered for this study, React Native is considered to be better than Ionic, but with new updates coming continuously, Ionic is improving every day.

Full textAbstract:
Afin de retrouver un paramètre efficace de la structure périodique, on s'est efforcé de développer la théorie de l'homogénéisation, qui considère la structure périodique comme un milieu homogène. Cette thèse porte principalement sur la proposition et la validation de l'homogénéisation classique et de second ordre. Une méthode d'homogénéisation est appliquée pour obtenir des paramètres efficaces de structures multicouches. De plus, une homogénéisation classique est adoptée pour calculer les propriétés de transmission de structures diélectriques multicouches et la relation de dispersion d'un réseau de cylindres métalliques monté sur un plan de masse métallique lisse. D'après cette relation de dispersion, la propriété de coupe-bande à une certaine bande de fréquences est découverte et est appliquée sur la reformation du diagramme de rayonnement de l'antenne à plaque traditionnelle en supprimant l'onde de surface propageant sur le plan de masse. Nous avons publié cette partie dans [22]. Nous démontrons expérimentalement une limitation importante de l'homogénéisation classique lors du calcul de la propriété de transmission d'un réseau métallique ultra-fin. Le coefficient de transmission mesuré est beaucoup plus faible que celui calculé par homogénéisation classique, bien que les interférences qui peuvent être causées par l'installation d’expérience imparfaite sont éliminées. Nous proposons donc une nouvelle homogénéisation de second ordre, qui permet d'obtenir le coefficient de transmission correspondant aux résultats numériques. De plus, l'homogénéisation de second ordre a été validée expérimentalement par plusieurs grilles métalliques de même dimension sauf l'épaisseurIn order to retrieve effective parameter of the periodic structure, people have made effort to develop the theory of homogenization, which regards the periodic structure as a homo- geneous medium. This thesis mainly focuses on the proposition and validation of classical and second order homogenization. A kind of method for homogenization is applied to ob- tain effective parameters of multilayer structures. Moreover, classical homogenization is adopted to calculate transmission properties of dielectric multilayer structures and the dis- persion relation of metallic cylinder array mounted on a smooth metallic ground plane. From the dispersion relation, its band gap property at a certain frequency band is revealed and is applied to reshape the radiation pattern of traditional patch antenna by suppressing the surface wave propagating on the ground plane. We have published his part of the work in [22]. We experimentally demonstrate one important limitation of classical homogenization when calculating the transmission property of an ultra-thin metallic grating. The mea- sured transmission coefficient is much smaller than that calculated by classical homoge- nization, although the interferences may be caused by the imperfect experiment facility are eliminated. Thus we propose a new second order homogenization, which is able to get the transmission coefficient correspondent to numerical results. Furthermore, second order homogenization has been experimentally validated by several metallic grating with the same dimension except for the thickness. This part of work will be included in a chapter of a book will be published by Intech Publisher

Thesis (MEng)--Stellenbosch University, 2015.ENGLISH ABSTRACT: The Smart Grid is an initiative to make the existing utility grid more effective and efficient by making utility infrastructure smarter. The initiative affects all areas of the utility grid and all utility hardware. Communication to utility hardware for monitoring and remote configuration is central to the smart grid vision. The focus of this project is the Smart Transformer, a distribution transformer with built-in intelligence and communication capabilities. Data acquisition and remote configuration hardware and software was developed and installed on a distribution transformer for application in deep rural areas. The solution included communication capabilities and adheres to industry standards. The solution was tested and data acquisition and management were done using the OSIsoft PI System software. Field tests were performed to evaluate the effectiveness of the solution in a deep rural setting. It was found that the smart transformer can be effectively monitored, configured and controlled in a deep rural setting. The smart transformer concept was investigated in a microgrid context. The potential of a smart transformer within a microgrid was explored and the smart transformer as a microgrid market-enabler was focussed on. A simulation was performed to evaluate the role of a smart transformer as a microgrid market-enabling device. It was found that the smart transformer has the potential to serve as a market-enabling device.
