Texte intégralRésumé :
Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para a obtenção do Grau de Mestre em Engenharia Informática.Among the information technology sectors is the virtualization sector, which stands out by being a very active area, with many collaborations and advances. Virtualization’s benefits are plenty. Some of them are the massive server consolidation, reduced cooling, structural and electrical costs and the isolation between virtual machines. Virtual appliance is a concept resulting from the advancements on virtualization, and defines an alternative software distribution model from those existing by then, such as the traditional CD-ROM distribution, software as a service and hardware appliances. This model allows customers to have their IT solution fully specified and optimized for the task it must perform. With the virtual appliance outbreak, many servers using different applications tend to gather on the same physical machine. The applications, in turn, may implement plenty configuration formats, from widely adopted standards to proprietary formats. The configuration of these applications is typically carried by busy system administrators, who must dedicate some of their time coping such a vast configuration format range. This thesis contributes for the nourishing of the virtual appliance concept and proposes the creation of a tool which automatically configures applications inside virtual appliances, regardless of the application being configured. The contributions on this area are, therefore, very rare, which elevates this dissertation to a pioneer of the area. The approach for the problem of automatic application configuration explores the frequently found patterns in configuration files. Typically, those files use similar concepts, such as parameter definitions, parameter blocks and comments. Besides this, only some files were found to implement other concepts, although on a punctual basis. This dissertation proposes a framework for the automatic configuration of applications based on this characteristic. A configuration file is transformed to a structured and application-independent language, like the eXtended Markup Language, which is then modified and reverted to its original syntax.

Locating a parking spot during peak hours in most populated areas like shopping malls, universities, exhibitions or convention centers is difficult for the drivers. The difficulty rises from not knowing where the available spots may be at that required time. Smart parking is a solution to metropolitan cities to reduce congestion, cut vehicle emission totals and save persons' time by helping them in finding a spot to park. Smart Parking is a parking system, usually a new one that is equipped with special structured devices (things) to detect the available parking slots at any parking area. This is an application based on Internet of Things (IoT) that in Real-Time environment have sensors and devices embedded into parking spaces, transmitting data on the occupancy status; and the vehicle drivers can search for parking availability using their mobile phones or any infotainment system that is attached to the vehicle. Hence the driver would know where there is an available spot to park his vehicle in less time, reducing the energy consumption and air pollution. The Client or the sensor posts the parking slot occupancy status to a web service URL. The Java based web service is built using Spring and Hibernate to connect to the backend system. The web service (.war) file is deployed on Apache Tomcat Server and the backend used is MySQL database.

Texte intégralRésumé :
This PhD thesis introduces basic concepts of smart chemical sensors design, which are afterwards applied to a particular application: the analysis of natural gas.
The thesis addresses thus two sets of objective, a first set of objectives related to the conceptual design of a smart chemical sensor using smart sensor standards:
- The design of an optimal smart chemical sensor architecture
- The novel combination in a working prototype of the highly complementary smart sensor standards IEEE-1451 and BS-7986
A second set of objectives is directly related to the selected application. Natural gas quality control. Natural gas is an energy source of major importance in the world energy supply, its quality control is increasingly important due to its origin-dependent properties and the progressive liberalization of the energy market. The objectives related to this application are:
- To solve the natural gas quality analysis problem by using a lower cost approach taking advantage of MEMS technology, smart sensor features, and embedded intelligent signal processing.
- To select suitable sensing technologies and associated signal processing.
An overall goal addressed by the PhD Thesis is in the end the reporting of a working smart sensor prototype implementing all the smart sensor features, MEMS based natural gas analysis and advanced signal processing as a demonstration of a novel low-cost and high speed natural gas analyzer.
The thesis covers this research along 7 chapters, introducing the concepts and application in chapters 1 and 2, the objectives in chapter 3, the simulation of a proposed MEMS sensor approach in chapter 4, the description of the advanced signal processing approach adopted in chapter 5, the description of the electronics and engineering of the smart natural gas analyzer prototype in chapter 6, and finally the conclusions of the work in chapter 7.La tesis introduce conceptos básicos sobre el diseño de sensores químicos inteligentes, en particular presenta los estándares propuestos IEEE-1451 y BS-7986, y elabora una propuesta para el diseño óptimo de dichos sensores químicos inteligentes. Se implementa la propuesta de diseño para una aplicación concreta, el análisis de gas natural. Además de la aplicación de los conceptos sobre sensores químicos inteligentes se pretende además diseñar un analizador compacto, rápido y de bajo coste, para ello se estudia el uso de un microsensor termoeéctrico como sensor principal del analizador. Una vez probada su viabilidad se implementan ambos conceptos (sensores inteligentes y microsensor termoeléctrico) en un prototipo funcional validado en laboratorio. Como resultado se obtiene una propuesta para el diseño de sensores químicos inteligentes basada en estándares, y por otro lado se presenta un nuevo analizador de gas natural, más rápido y compacto que los existentes. Los resultados obtenidos originan diversas publicaciones en revistas así como dos patentes de método y sistema.

Texte intégralRésumé :
Methods for uncertainty quantification (UQ) and mitigation in the electrical power system are very basic, Monte Carlo (MC) method and its meta methods are generally deployed in most applications, due to its simplicity and easy to be generalised. They are adequate for a traditional power system when the load is predictable, and generation is controllable. However, the large penetration of low carbon technologies, such as solar panels, electric vehicles, and energy storage, has necessitated the needs for more comprehensive approaches to uncertainty as these technologies introduce new sources of uncertainties with larger volume and diverse characteristics, understanding source and consequences of uncertainty becomes highly complex issues. Traditional methods assume that for a given system it has a unique uncertainty characteristic, hence deal with the uncertainty of the system as a single component in applications. However, this view is no longer applicable in the new context as it neglects the important underlying information associated with individual uncertainty components. Therefore, this thesis aims at: i) systematically developing UQ methodologies to identify, discriminate, and quantify different uncertainty components (forward UQ), and critically to model and trace the associated sources independently (inverse UQ) to deliver new uncertainty information, such as, how uncertainty components generated from its sources, how uncertainty components correlate with each other and how uncertainty components propagate through system aggregation; ii) applying the new uncertainty information to further improve a range of fundamental power system applications from Load Forecasting (LF) to Energy Management System (EMS).In the EMS application, the proposed forward UQ methods enable the development of a decentralised system that is able to tap into the new uncertainty information concerning the correlations between load pattern across individual households, the characteristics of uncertainty components and their propagation through aggregation. The decentralised EMS was able to achieve peak and uncertainty reduction by 18% and 45% accordingly at the grid level. In the LF application, this thesis developed inverse UQ through a deep learning model to directly build the connection between uncertainty components and its corresponding sources. For Load Forecasting on expectation (point LF) and probability (probabilistic LF) and witnessed 20%/12% performance improvement compared to the state-of-the-art, such as Support Vector Regression (SVR), Autoregressive Integrated Moving Average (ARIMA), and Multiple Linear Quantile Regression (MLQR).

Texte intégralRésumé :
Smart home technology and IoT is rapidly gaining popularity, and many systems use mobile applications to control the hardware in the homes of the owners. Connective created by Indentive is one such system, which allows users to control things like the temperature in their homes via their smartphones. However, the usability of applications such as this one can be limited, which leads to frustration and even loss of interest for the users. This can result in critical implications for the company producing such a system – both economically and in regards to popularity. It is therefore important for companies to detect issues with their systems early on in order to address these issues and prevent negative implications. Connective was thus tested in a qualitative study using contextual inquiries with 7 participants. The data from the inquiries was then structured through thematic analysis, and the usability of the application was also tested using SUS-evaluation. Wireframe suggestions for changes to the application were then brainstormed with the thematic analysis and the result of the SUS in mind. Major issues that were addressed were access to help, information, the layout, the handling of errors, and feedback. Future studies should include further, more in-depth qualitative studies, perhaps in combination with quantitative data, to further improve and develop the wireframe-suggestions into working prototypes that can then be user tested.

Yuan, S. « Magnetic field energy harvesting for Smart Grid application ». Thesis, University of Liverpool, 2016. http://livrepository.liverpool.ac.uk/3003026/.
Texte intégralRésumé :
Real-time data of power infrastructures collected by wireless sensors are the foundation of many smart grid applications. However, the finite life span of the batteries which power the wireless sensor becomes a bottleneck problem as it is expensive to periodically replace these batteries. Energy harvesting can be an effective solution for autonomous, self-powered wireless sensors. In the vicinity of high voltage/current equipment, a strong magnetic field is generated, which could be a consistent energy source. The purpose of this thesis is to present a comprehensive study into a magnetic field energy harvesting system which mainly consists of coil and rectifying circuit with the ultimate goal to obtain the maximum energy as efficiently as possible for a given condition. The main contribution of this thesis is in two research areas: The first area is about the design of an energy harvesting coil. The ferromagnetic core is the most important part to determine the output power from the whole energy harvesting system. Thus, the precise knowledge of ferromagnetism is critical. As the harvesting coil may not fully enclosure the current conductor, the demagnetization factor which is closely related to the core geometry is carefully studied and minimized. Two new core shapes have been proposed and optimized to have much lower demagnetization factors (hence more power) than that of a conventional rod. 1. A bow-tie-shaped core is introduced and designed to have two large end surfaces. By making its two ends broader, more magnetic flux can be guided from the air into the ferromagnetic core. This intensifies the magnetization at the middle of the core where the wire is wound on. 2. A new helical core is introduced as a further improved version of the bow-tie core. It utilizes two big circular plates fitted at the both ends for the flux collection. In the middle, a helical-shaped core is introduced to increase the path of the magnetic flux. Therefore, the separation between the north pole and south pole is lengthened dramatically, which leads to a reduction in the demagnetization factor and an increase in the magnetic flux density. In addition to the core shape, the selection of the core material is studied and found that high permeability ferrite is the most suitable core material due to its high relative permeability and ultra-low conductivity. Thus, the eddy current losses in the ferromagnetic core can be significantly reduced. Experimental results show that the proposed helical coil with only 400 turns of wire can have a power density of 2.1 μW/cm3 when placed in a magnetic flux density of 7 μTrms. This value is 17 times greater than a previously reported design with 40,000 turns of wire (0.12 μW/cm3 ) placed in the same magnetic field. If a longer helical coil with 8,000 turns of wire is placed in a magnetic flux density of 11 μTrms, the produced power density is around 131.4 μW/cm 3 which is comparable to a solar panel working during a cloudy day. The second area is about the rectifying circuit design which utilizes the energy harvested from the coil to power a commercial wireless sensor. A voltage doubler is applied to provide full-wave rectification and simultaneously boost the output voltage. A transient analysis is carried out to calculate the input resistance of a charging capacitor as a function of time. The theoretical analysis indicates that the input resistance is highly related to the input and output voltages. Therefore, a conventional matching network which consists of linear components cannot work well. A switch mode power converter is introduced as a matching network so that the charging capacitor can be isolated from the harvesting coil. The emulated input resistance looking into the power converter is a constant and determined by the frequency and the duty cycle of the power width modulation applied on the switch. The system is designed and made. The experimental results demonstrate that the energy conversion efficiency from the harvesting coil to the storage capacitor is around 74.6% which is twice as large as a previously reported design. Finally, an energy management unit is developed and it effectively utilizes the energy stored in the capacitor to power a commercial wireless sensor. It is shown in this thesis that a highly efficient magnetic field energy harvesting system has been successfully demonstrated. A wireless sensor can be properly powered up by using a small coil (15 cm long) placed in a small magnetic flux density (7 μTrms). The proposed solution is a very efficient and attractive method for harvesting the magnetic field energy for a wide range of smart grid applications.

Texte intégralRésumé :
Le but de cette thèse est de concevoir et mettre en œuvre une stratégie de renseignement sur les menaces cyber afin de soutenir les décisions stratégiques. L'alerte précoce et la détection des violations sont décisives, ce qui signifie que l'accent de la cyber sécurité a évolué vers l'intelligence des menaces. Pour cette raison, nous avons créé, analysé, mis en œuvre et testé deux solutions. La première solution agit comme un mécanisme prédictif et proactif. C'est un nouveau cadre utilisé pour analyser et évaluer quantitativement les vulnérabilités associées à un réseau de villes intelligentes. Cette solution utilise le modèle de chaîne de Markov pour déterminer le niveau de gravité de vulnérabilité le plus élevé d'un chemin d'attaque potentiel du réseau. Le niveau de gravité élevé amènera l'administrateur système à appliquer des mesures de sécurité appropriées à priori aux attaques. La deuxième solution agit comme un mécanisme défensif ou auto-protecteur. Ce cadre atténue les attaques par disponibilité zero-day basées sur Identification, Heuristics et Load Balancer dans un délai raisonnable. Ce mécanisme défensif a été proposé principalement pour atténuer les attaques par déni de service distribué (DDoS) car elles sont considérées comme l'une des attaques de disponibilité les plus sévères qui pourraient paralyser le réseau de la ville intelligente et provoquer une panne complète. Cette solution repose sur deux équilibreurs de charge dans lesquels le premier utilise une approche heuristique et le second agit comme une sauvegarde pour produire une solution dans un délai raisonnableThe purpose of this thesis is to design and implement a cyber-threat intelligence strategy to support strategic decisions. Early warning and detection of breaches are decisive to being in a state of readiness, meaning that the emphasis of cybersecurity has changed to threat intelligence. For that reason, we created, analyzed, implemented, and tested two solutions. The first solution acts as a predictive and proactive mechanism. It is a novel framework used to analyze and evaluate quantitatively the vulnerabilities associated with a smart city network. This solution uses the Markov Chain Model to determine the highest vulnerability severity level of a potential attack path in the attacks graph of the network. High severity level of a potential attack path will lead the system administrator to apply appropriate security measures a priori to attacks occurrence. The second solution acts as a defensive or self-protective mechanism. This framework mitigates the zero-day availability attacks based on Identification, Heuristics and Load Balancer in a reasonable time frame. This defensive mechanism has been proposed mainly to mitigate Distributed Denial of Service (DDoS) attacks since they are considered one of the most severe availability attacks that could paralyze the smart city’s network and cause complete black out. This solution relies on two load balancers in which the first one uses a heuristic approach, and the second acts as a backup to produce a solution in a reasonable time frame

The later was designed to provide suitable voltage level and interface for the loads connected. PVSyst model was built and set to be located in Ulm, Germany. The design parameters were set, and different set of orientations were tested for each module. The simulation results showed bifacial module delivered a reliable PV system in case of south and south-east orientation and achieved better performance in other orientations in comparison to the other PV modules implemented. Due to limitations in PVSyst software the results provided had an overall uncertainty of 5%. The microcontroller was able to process the data from the radar sensor and DAQ card and perform fast Fourier transform (FFT). However, further processing of motion detection was complex to be included in the thesis work. The radar sensor and DAQ card provided signals with uncertainty of ± 3.4 mV. The RF wireless communication module transmitted signal over various ranges up to 150 m with time delay of 500 ms.

Texte intégralRésumé :
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.

Texte intégralRésumé :
Approved for public release; distribution is unlimitedThis research explores methods to increase the performance of HTTP traffic when operating on a network that is prone to disrup-tions. The SmartNet architecture is presented as an open and extensible software framework for experimenting with and deploying application-transparent network optimization solutions, including the incorporation of the disruption tolerant networking (DTN) and split TCP (SplitTCP) technologies into an IP network. The architecture fashions a plugin-based system architecture where each plu-gin implements a small set of application or transport protocol specific network adaptations that can be chained with other plugins to form a packet processing pipeline. The SmartNet framework is implemented along with plugins to route packets through native-IP, the Bundle Protocol, or SplitTCP. Performance of the SmartNet is measured under five network disruption patterns and five link speeds. The results conclude that HTTP performance can be increased by using the SmartNet to transparently route packets over the DTN bundle protocol or SplitTCP when the network is prone to disruptions.

Blockchain is a distributed ledger technology that records exchanges of value between parties securely, permanently, and in an easily verifiable manner. It is the technology underlying cryptocurrencies such as Bitcoin and Ethereum. Although initially used for financial transactions, blockchain's applications extend beyond finance and can impact a wide variety of industries. One such application is in supply chain management. With multiple stakeholders and business transactions, supply chains are inherently complex. Many challenges exist, including the lack of transparency and traceability, difficulty in managing risks and disruptions, and the need to build trust and reputation. Blockchain technology ushers in the potential to solve these challenges through the use of smart contracts. Smart contracts are digital agreements between transacting parties that are written in computer code and deployed to the blockchain, where they will self-execute when predetermined conditions are met. They reduce complexity in a supply chain through automated verification and execution of the multiple business transactions involved. A decentralized, immutable record also ensures all stakeholders have equal access to information and helps build trust. Smart contracts improve the transparency, traceability and efficiency of a supply chain, allowing it to be more agile while strengthening relationships among stakeholders. In this thesis, I create a proof-of-concept to explore the application of smart contracts in supply chain management. The proof-of-concept consists of three smart contracts, coded in Solidity, that can be integrated to determine the provenance of goods, track the chain of custody as goods flow through a supply chain, automatically execute payment upon fulfillment of criteria, and maintain an open database of stakeholders with a score indicating their reputation. I validate the proof-of-concept using the Ethereum platform, which was specially conceived for smart contract and decentralized application development. Preliminary testing shows that the contracts are able to interact with one another and execute their functions as intended. Further testing is necessary to evaluate the performance of the contracts on the live Ethereum network, and integration with smart sensors should be explored to create a more viable real-world solution.

Texte intégralRésumé :
Smart Materials have been investigated for decades and widely used in the automotive and aeronautics industries to measure and control noise and vibration. This study covered ship structure vibration and Smart Materials were employed for the purpose of ship vibration attenuation. One specific Smart Material, piezoelectric material, was the focus of the study. Although previous research has been conducted on vibration mitigation employing piezoelectric shunt systems, this study identified the need for specific applications regarding ship vibration mitigation. Passive piezoelectric shunt damping systems for ships were described and investigated in this study. Computational methods were used to investigate structural vibration of a cantilever beam, a Liquid Natural Gas (LNG) carrier and a bulb keel. The Finite Element Method (FEM) was used to calculate the vibration and vibration treatment with the passive piezoelectric shunt damping system. The numerical results of the passive piezoelectric shunt system bonded to the cantilever beam were compared to experimental results obtained from a previous study. The FEM delivered results, which showed a high degree of similarity in comparison to the experimental results. Both experimental and numerical studies validate the theory that piezoelectric material, connected to an electrical circuit, can be successfully used to achieve vibration reduction. Significant vibration attenuation was found in the numerical simulation of the LNG vessel. The simulation of the bulb keel also provided promising outcome regarding substantial vibration reduction by means of piezoelectric shunt system.

Texte intégralRésumé :
Nowadays, we hear much about smart grids as a promising idea that will have a direct impact on our life of tomorrow. Research, articles and standards are also numerous on this subject. Among them, IEC 61850 is an important standard about communication which could have a big influence on electrical substations or even power plants in the future. However, the feasibility of this standard has been little investigated. This study has been done with Tractebel Engineering France, which is a branch of GDF Suez. They have good expertise on hydro power plant, but their projects can also cover electrical substations and electrical transmission lines. Smart grid’s development can have direct impacts on their activities. The study presents firstly the different aspects of smart grid, in order to know the logic of motivations and the interesting points for the company. A certain emphasis has been put on the electrical gird functioning aspect as well as renewable energies, because they seem to be especially important for Tractebel. Secondly, the study is focused on the main aim of this article, the feasibility of IEC 61850 to a substation of Tractebel’s Kaléta project. A presentation and analysis of essential notions of the standard 61850 has been done in chapter VII. In the following chapters, the study tries to make a judgment of the feasibility by analyzing the aspects of software, modeling and practical functioning of the substation. The study concludes that despite the fact that IEC 61850 seems to be the standard of the future, it is still premature today for Tractebel to use it in the case of Kaléta. Due to the independent software tools’ complexity and the lack of interoperability between different components, the modeling process remains complicated if we don’t want to choose a software program provided by a specific equipment supplier. Moreover, the functioning of an IEC 61850 substation requires new skills for the staff, which could be another practical problem for Kaléta.

The world is becoming smarter with an increase in efficiency of wireless communication resulting in an accelerated use of smart phones. Open source of Android market gave a chance to individuals to freely develop their own applications which could be run easily on Android smart phones. The purpose of this project is to develop an Android application for managing and tracking a user’s shopping information. The Smart tracker is about tracking the user's purchase of clothes and accessories. The main advantage of this Android app is that it helps to remember the size of clothing purchased. When a user shops at a retail store, he feeds the information pertaining to the fitting of the clothes purchased brand wise, whether it is a correct fit or a bit loose/tight. The data thus entered can be retrieved when he decides to make a purchase in the same store in future. This tremendously decreases the user’s shopping time and makes the experience easier as the right size is already known and hence there is no hassle of using trial rooms to see if the clothes fit. In addition to size, Smart tracker also stores the price at which the item was bought and any additional user comments along with the store location. When data pertaining to a purchased clothing item is entered, the app provides the option to append an image of the item either by capturing a picture through the smart phone’s camera or by uploading an image from the gallery. This helps the user recount the item to which the information corresponds. Another important feature is that tracking of purchases for a family can be personalized, i.e., the shopping information of each family member can be stored separately (especially for kids who can't track their own expense). Additionally, the user can also keep track of money spent on each item/brand/family member. Smart tracker also enables user to create a wish list to remember what they (or a friend) liked but didn't buy in a particular store.

Texte intégralRésumé :
This thesis describes the development of an IOT application based upon Digitizing a smart door lock for making it connected to the internet and able to recognize employees that work in the office. This thesis concentrates primarily on the security aspects by listing the typical security challenges in IOT systems in general and summing these challenges up to develop a functional and secure product from scratch. A microcontroller is chosen for this project and a test environment is built to experiment and develop the security breaches. Architectural designs are chosen for the API being developed and even for the Android Application. A detailed description is made of the multi-master database represented by Azure active directory and its importance to achieving the security of an essential security breach. A new technique called Eddystone is introduced in the project to serve the transmission protocol with Bluetooth beacons. The final stage of this project is completing the development of the Android application and making sure that all the subsystems developed do communicate with each other, to deliver a functional and secure flow of the IoT system.Följande examensarbete beskriver utvecklingen av en IoT-produkt baserad på digitalisering av ett smart dörrlås där applikationen ansluts till internet för igenkänning av anställda som arbetar på ett kontor. Examensarbetet fokuserar primärt på säkerhetsaspekterna genom att notera de typiska säkerhetsutmaningarna som generella IOT-system utsätts för och summerar dessa utmaningar för att utveckla en funktionell och säker produkt från start av projektet. En mikrokontroller väljs ut specifikt för projektet och en testmiljö byggs för att undersöka och motverka eventuella säkerhetsbrister. Rapporten ger även detaljerad beskrivning av multi-master databasen Azure Active Directory och dess betydelse för att uppnå önskad säkerheten i systemet.

Texte intégralRésumé :
The ability to estimate positions of sound sources is one that gives animals a 360° awareness of their acoustic environment. This helps compliment the visual scene which is restricted to 180° in humans. Unfortunately, deaf people are left out on this ability. Smart phones are rapidly becoming a common tool amongst mobile users in developed and emerging markets. Their processing ability has more than doubled since their introduction to mass consumer markets by Apple in 2007. Top-end smart phones such as the Samsung Galaxy Series; 3, 4, and 5 models, have two microphones with which one can acquire stereo recordings. The purpose of this research project was to establish a feasible Sound source localization algorithm for current top-end smart phones, and to recommend hardware improvements for future smart phones, to pave way for the use of smart phones as advanced auditory sensory devices capable of acting as avatars for intelligent remote systems to learn about different acoustic scenes with help of human users. The GCC-PHAT algorithm was chosen as the underlying core DOA algorithm due to its suitability for pair-wise localization as highlighted in literature. A stochastic power accumulation algorithm was designed and implemented to improve estimation outcomes by GCC-PHAT. This algorithm was based on inspiration from W-disjoint orthogonality assumption in literature and was extended to perform sound source counting and time domain source separation. The system yielded satisfactory azimuth estimates of sound source directions in real time with pin-point DOA estimation accuracy rates of 64%, and 90.67% accuracy rate when a tolerance of ± 1 correlation sample is considered. An effort to resolve front back ambiguity using phone orientation data from the MEMs sensors yielded un-satisfactory results prompting a recommendation that an extra microphone would be needed to achieve 360° localization in a more user friendly way. The dissertation concludes with plans for further work on the topic and provision of a further refined API and optimised libraries to facilitate development of customised solutions using this system.

Texte intégralRésumé :
In this thesis I present the design of hydrophobic hybrid inorganic-organic coatings via Lotus leaf-like and Slippery Liquid Infused Porous Surfaces (SLIPS) approaches with anti-wetting performance in cold environments. In the temperature range from -10 to 0°C, a maintenance of a low water contact angle hysteresis (<15°) for all the SLIPS developed is reported.
Moreover, the evaluation of the icing nucleation delay and the ice adhesion force of the designed coatings is reported. SLIPS exhibited an increase of ice nucleation delay time if compared with bare substrate and a huge decrease of ice adhesion. In conclusion, designed samples are characterized in Ice Wind Tunnel to simulate the impact of supercooled drops on the designed coatings. The results confirmed the efficiency of the SLIPS with a consistent decrease of ice accumulation with respect the base substrate.
SLIPS also achieved good stability in cold environment, stood out as a key issue for further development at larger scale.

Texte intégralRésumé :
As important components of intelligent transportation system, lane detection and tracking (LDT) and lane departure warning (LDW) systems have attracted great interest from the computer vision community over the past few years. Conversely, lane markings recognition (LMR) systems received surprisingly little attention. This thesis proposed a real-time lane assisting framework for intelligent vehicles, which consists of a comprehensive module and simplified module. To the best of our knowledge, this is the first parallel architecture that considers not only lane detection and tracking, but also lane marking recognition and departure warning. A lightweight version of the Hough transform, PPHT is used for both modules to detect lines. After detection stage, for the comprehensive module, a novel refinement scheme consisting of angle threshold and segment linking (ATSL) and trapezoidal refinement method (TRM) takes shape and texture information into account, which significantly improves the LDT performance. Also based on TRM, colour and edge informations are used to recognize lane marking colors (white and yellow) and shapes (solid and dashed). In the simplified module, refined MSER blobs dramatically simplifies the preprocessing and refinement stage, and enables the simplified module performs well on lane detection and tracking. Several experiments are conducted in highway and urban roads in Ottawa. The detection rate of the LDT system in comprehensive module average 95.9% and exceed 89.3% in poor conditions, while the recognition rate depends on the quality of lane paint and achieves an average accuracy of 93.1%. The simplified module has an average detection rate of 92.7% and exceeds 84.9% in poor conditions. Except the conventional experimental methods, a novel point cluster evaluation and pdf analysis method have been proposed to evaluate the performance of LDT systems, in terms of the stability, accuracy and similarity to Gaussian distribution.

Texte intégralRésumé :
The aim of this thesis is to identify alternatives for the integration of smart cards into a classic Kerberos system. Some researchers have proposed specific solutions. Each proposal appeared to be limited and, hence, there was a need to identify what other approaches were available.
It was identified that smart cards can be added to each of the interfaces of Kerberos (user to authentication server, user to ticket granting server and user to application server). It appears most appropriate to use smart cards in the user to Authentication Server interface. The user's workstation is trusted with application data and so it will be usually appropriate for the application session keys to also be trusted to the user's workstation.
The smart card can be integrated into the user to Authentication Server messaging implementation so that the user's authentication information is never exposed to the workstation. Six options have been identified for the integration in this interface.
Some of the concepts developed were prototyped in order to identify the practicality of the suggestions. An early beta release of Kerberos from Massachusetts Institute of Technology was used as the base for prototyping.
It was found that complex protocols, such as Zero Knowledge Protocols, cannot be implemented on today's smart cards without special customisations by the smart card vendors. However, protocols that only required the use of common cryptographic functions such as DES (Data Encryption Standard) and RSA (Rivest, Shamir and Adleman) can be implemented.

Texte intégralRésumé :
Active ageing is presented as a potential panacea for the challenges faced due to population ageing. Work presented in this Thesis improves the integration and evaluation of sensor technology, embedded within a clothing system, designed specifically for the active ageing. A review of wearable sensors highlighted issues involving sensor integration, placement, validation and the effects of body shape and size as key challenges. These issues guided the focus of four studies within the Thesis. A study assessing the effect placing an accelerometer within clothing had on step count accuracy has been undertaken. Results demonstrated that a reliable step-count can be achieved from accelerometers placed within clothing at the sternum, waist or lower back. Subsequently, an investigation into the optimal location of an accelerometer to classify a range of everyday activities was perfonned. Results demonstrated data from the hip as the best single location to perfonn activity recognition. Following on from this, 3D body scanning was used to assess the effect of adiposity on the accuracy of step count obtained from an accelerometer. This study established that neither BMI, waist circumference nor ABVol had an effect on step count accuracy obtained from an accelerometer placed at the chest, waist or lower back. This adds clarity to the current inconsistencies within the literature. Considering a different fonn of sensor technology, the perfonnance of textile electrodes, integrated within custom fitted garments was investigated. Performance tests indicated that the custom garments did not perform accurately during tasks which included movement of the arms and torso. The performance during these tasks, did, however, vary considerably between subjects. The incorporation of these findings within the design of smart garments will help to ensure that wearable sensors and systems meet their potential, particularly in the role of supporting the health and wellbeing of an active ageing society.

Khazravi, Mojtaba. « A micro pump for drug delivery application using smart actuators ». Thesis, University of Leeds, 2012. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.582094.
Texte intégralRésumé :
This thesis details the fabrication of a smart actuator driven micro pump. The proposed pump was designed to take the advantage of a smart actuator used in drug delivery applications. Although advances in medicine have improved patients' chances against most diseases, conventional treatments and medications are not yet entirely efficient in terms of curing some diseases. For critical diseases and those difficult to cure, such as cancer and diabetes, state-of-the-art drug delivery systems could improve the treatment process and control or otherwise eliminate the complications associated with various illnesses owing to improved and more efficient drug delivery. Diabetes has been chosen as the primary target disease to be addressed in this project. Since the introduction of insulin delivery pumps during the 1970s, this type of drug delivery system has improved significantly; however, drug delivery systems currently available have various intrinsic practical problems. For example, they are rather large and heavy, and carrying such bulky devices can limit patients' mobility and their daily activities. On the other hand, they require user intervention, which can compromise their effectiveness. Moreover, such devices must be attached securely to the body via a catheter and pipe in order to deliver the drug; therefore, a fully automatic and miniaturised patch-like drug delivery system could offer valuable advantages over current devices. This project's approach towards solving the problem is to devise a novel micro pump through the use of smart actuators. In the proposed micro pump, the actuator and the diaphragm are integrated into one single part, thus eliminating most of the pump's moving parts compared with conventional pumps. Moreover, novel diaphragm designs are proposed. Smart actuators have a wide range in terms of materials and specifications; they can be solid, like quartz crystal, or flexible, like ionic polymer gel. Based on the outcome of the literature review for smart actuators, the ionic polymer metal composite (otherwise referred to as IPMC) was chosen to run the proposed micro pump owing to its low power consumption and. driving voltage, as well as good power-to-weight ratio. In order to characterise the IPMC actuator behaviour, proper test rigs and devices were devised and maximum displacement and force for different actuator strips and diaphragm setups were measured. The work carried out on the required calculations, modelling and simulation, is reported for both strip and diaphragm actuators. The results of the experiments on strips, diaphragms and pumps are presented in the respective chapters, highlighting the fact that, by constraining the actuator in any way, their maximum force and displacement output will be limited; thus, novel diaphragm designs are proposed. The result of the actuator experiments and the requirements of the diabetic patients, as studied in the literature review, were used to design the. micro pump itself. For the diaphragm and pump chamber, a rectangular shape was chosen owing to improved alignment in the final patch layout and higher compatibility with various IPMC diaphragm designs. In order to maximise the pump efficiency, various valve designs were studied and tested. Owing to the small displacement of the diaphragm, the valve backlash and opening force were found to be vitally important. Furthermore, the calculations, modelling and simulation work carried out on the pump are presented in this thesis. The experiments on the proposed micro pump, with its novel diaphragm design, showed that the required amount of drug can be transferred in time. The fabrication of this pump is the first step towards achieving the ultimate goal of developing a cutting-edge disposable insulin drug-delivery patch in the future.

Texte intégralRésumé :
The adaptive serrated nozzle (ASN) is one of the most promising concepts to help reduce the noise level generated by aero-engines. Shear between a hot air stream and ambient air at the nozzle exit creates noise. The serrated nozzle is designed to protrude into the air stream causing mixing between the two air streams reducing the noise level. Adaptive control system using shape memory alloy (SMA) actuators deploy the protrusion only when required in order to maximise fuel efficiency. The successful joining of NiTi shape memory alloy (SMA) to the titanium parent structure is critical to the development of the adaptive serrated nozzle. However, joining of SMAs to dissimilar metals is widely known as extremely difficult if not impossible. This research provides a preliminary study into the potential of using SMAs in large engineering applications such as the ASN and the development of viable joining methods for joining SMA to titanium based alloy. Five most favourable conventional joining methods were selected for experimental investigation. Results proved that the successful joining of SMA to dissimilar alloys was extremely difficult, joint failures were mainly due to the formation of brittle intermetallics at joint interfaces. The formation of these intermetallics occurs irrespective of the type of joining method and level of heat input employed. However, it has been shown that the formation of these intermetallics can be suppressed by the manipulation of the joint composition. A marked improvement in joint performance has been achieved for joints that contained no more than 25 at% nickel. Joint improvement has also been achieved through the addition of titanium at the joint, although further research is necessary to investigate the effect of titanium addition to joint performance.

This dissertation proposes a location-based access control model, named Smart-RBAC, extending the functionality of Role-based Access Control Model (RBAC) by including user’s location as the contextual attribute, to solve the aforementioned problem. Smart-RBAC model is designed with a focus on content delivery to the user in order to offer a feasible level of flexibility, which was missing in the existing location-based access control models. An instance of the model, derived from Liferay’s RBAC, is implemented by creating a portal application to test and validate the Smart-RBAC model. Additionally, portlet-based applications are developed to assess the suitability of the model in a smart campus environment. The evaluation of the model, based on a popular theoretical framework, demonstrates the model’s capability to achieve some security goals like “Dynamic Separation of Duty” and “Accountability”. We believe that the Smart-RBAC model will improve the existing smart campus applications since it utilizes both, role and location of the user, to deliver content.

In this paper, we propose an application framework for pervasive computing. In this framework, we divide services into two types: Active Services and Passive Services and we will take the changes in the real situation as "Event". By using the events, the Active Service will be driven so that it can offer the service for the user automatically. Then, we can set up an application called "Smart Campus" based on the framework. Take the activities in the campus as an example, the first step will be list all the activities in the campus and present them with Event Format, which means all the activities will be shown as “Who, How, when, where, What”. Therefore, "Smart Campus" can see the whole pictures campus by collecting and interpreting these events. Then, it can inform the related staff. In other word, Smart Campus have the character of pervasive computing, which means it is Fully Distributed, Context-Awareness and can blend the computing into daily life.

This study aims to explore the characteristics of smart contracts in the blockchain: users can't deny that all changes can be tracked and recorded, it is difficult to tamper with credibility, confidentiality, to achieve the convenience of planning for the Pre Need funeral contract. Because of the rapid transformation of modern society, people have become gradually enlightened for the concept of endowment and end of life, and it is a task that everyone has to face the arrangement funeral. However, in the face of the end of life, people are still powerless for their own arrangements funeral, and in today’s society, the majority of people are degraded. People are still unable to arrange their own affairs behind the scenes, so the Pre Need funeral contract has become a way for people to confess things behind. However, the domestic contractual contractors only introduced stereotyped Pre-Need contracts, and most of the pre-Need contracts cannot meet individual needs. In the end, they returned to the origin to allow the burial industry to ask for permission so that future generations would be overwhelmed. The blockchain is a technology has started to develop for several years. It has become more mature in the development of smart contracts. Therefore, the purpose of this research is to explore the possibility of applying the content of a lifetime contract through the application of smart contracts in order to reach the individual’s wishes. The autonomy and convenience of the contract. Blockchain technology is open and transparent, and it cannot be faked. A program executed on a blockchain platform through smart contracts can ensure that the program will not be tampered with, and that all execution records can be completely preserved so that the lifetime contract can be achieved through this technology to facilitate the process of transparency and popularity. Help consumers to plan Pre-need faster, easier, safer, more professional and more transparent.

The use of smartphones worldwide is growing very fast. Since the advent of online application stores, hundreds of thousands of applications have become instantly available to millions of smartphone users, but also the malicious attacks have increased. Reverse Engineering on malware analysis is a process which is used on malware in order to understand its operation, code structure and its functionality. This paper aims to understand the operation of a malware and investigate the parameters, code and structure which is created or modified by the android malicious application, and the relationship of smartphone hardware, android operation system and android application. In response to this objective a virtual lab was created to analyze malwares named “DroidDream” and “DroidDream Light” which infected Android platforms. After the Code analysis we understood the malicious piece of code which was embedded along with the original code, the mobile information which is sent to the remote servers, and once the malware gets the root access of the victim machine it can even damage the system. Let us can improve our defensive capabilities of smartphone malware attacks and the ability of the police digital forensics.

The target of this study is to develop a smart antenna array for mobile communication application, so as to improve the transmission efficiency and interference suppression. The center frequency of 2.4 GHz is chosen, which is one of the ISM band (Industrial Scientific Medical Band) and is commonly used for WLAN (IEEE 802.11b / IEEE 802.11g), Bluetooth, and ZigBee applications. Most of the conventional antenna designs for mobile application are omnidirectional ones because the signal may come from any direction. However, this does not lead to optimal data transmission performance and the antenna will also receive interferences from all directions. Since the wanted signal comes from a particular direction only, we propose an antenna array for mobile devices, in which the relative phases of the antenna elements are varied in a way that the main beam of the radiation pattern can be set to the desired direction with suppression of undesired interferences from other directions. This work employs a 2×2 patch antenna planar array on a PCB (printed circuit board) size of 200 mm ×137.5 mm, which is about the size of a 7.9 inch tablet. The relative phase of the antenna feed is controlled by digital phase shifters. The main beam of proposed antenna array can be set to four directions, which are the east, west, south, and north sides. The measured bandwidth for 10 dB return loss is about 4.6%, with a peak gain of 1 dBi and a HPBW (half-power beam width) of about 50 degree. It can be applied to the back of tablet of size larger than 7.9 inch for improving the transmission efficiency and interference suppression.

This research introduces the applications of smart card in various industries. We discuss the possibilities of distribution models, and emphasize the necessity of system integration by bringing in the progression of system. Furthermore, this research talks about the most popular smart card systems in Taiwan, and evaluates the possibilities of integration. The ultimate goal for the smart card system is to develop an open system. Because limiting smart card in one industry or applying smart card in only the simple applications would not meet the need of customers, distributing within multiple industries will be an inevitable trend. In order to establish an open system for smart card, transportation industry has to be one of the participants because of its stable demand and low substitutability. The success of Octopus system has proven this argument. In this research, we choose financial and retailing industries as the cooperating partners for transportation industry, and further discuss the possible distribution models. Due to the uniqueness of financial industry, there is no existing usage of smart card in Taiwan. Since transportation industry is our main focus, we discuss the characteristics of three existing smart card system from Northern, Middle, and Southern part of Taiwan. We also discuss the possible obstacles against smart card. As for retailing industry, we use 7-11, with its advantageous powerful distribution network, as example. With so many existing systems in Taiwan, it is necessary to integrate them before developing an open system. In the last part of this research report, we suggest that the integration should start with Taipei Smart Card and spread to Southern part of Taiwan through Taiwan’s railroad system. In the end, we also provide solutions to the major challenges for government, transportation industry, retailing industry, and financial industry.

THESIS ABSTRACT Graduate Institute of Business Administration National Taiwan University Name: Gi-Ming Wang Month/Year: Jan 1999 Advisor: Jong-Tsong Chiang Diffusion and Application Analysis of Smart Cards As an information system product, a smart card incorporates an IC chip that functions like a microcomputer in logic computation and database management. Therefore smart cards can be used to replace many existing systems in, for example, payment and security mechanisms. Furthermore, businesses in various industries, based on their infrastructures, can cooperate to develop appropriate functions in their smart card systems to provide customized services and create value for all participating parties. Because a smart card system represents a cross- industry convergence and consists of multiple members with varying interests, this thesis applies a five-layer approach to analyze the industry structure of smart cards. Besides, the thesis identifies three principal constituents of smart cards ─ service providers, technology providers and customers. Through a mechanism of positive causal loops, these three parties create and capture values on the basis of the common platform and form a community of common interest. One critical issue is the degree of openness of the smart card system. In promoting a smart card system, the initiators should first of all consider the characteristics of their infrastructures and understand the needs of their customers. While designing the appropriate system, they may have to seek and cooperate with partners with complementary assets. Through marketing, they attract and establish relationships with customers. If they can push the customer base to reach a so-called critical mass, the resultant network externalities can attract more customers, reinforce their expectation of benefit from this smart card system, and create a growth of interesting return for initiators.
