Résumé :

Object detection is particularly important in robotic applications that require interaction with the environment. Although 2D object detection methods obtain accurate results, these are not enough to provide a complete description of the 3D scenario. Therefore, many models have recently showed promising progress in this challenging field. In this work, the goal is to predict 3D bounding boxes from single images without using temporal data or any explicit depth estimation. We propose an approach for 3D monocular object detection based on Deep3DBox. We replace the geometric constraints taken into account to predict the 3D location of objects by a deep learning module. Moreover, we undertake a study on the different parameters for the modules that are used to predict dimensions and orientation of objects. We conduct experiments in order to search for the best hyperparameters of our model for KITTI cars and we report and compare our results on KITTI and the challenging NuScenes benchmarks for cars and pedestrians with other state of the art methods. Therefore, we conclude that our approach performs on par with similar methods and improves Deep3DBox results.
Objektsdetektion är särskild viktigt i robotikapplikationer som kräver interaktion med miljön. Fastän metoder för objektssdetektion i 2D ger precisa resultat, så krävs det mer för en komplett beskrivning av 3D-scenariot. Därför har flera modeller nyligen visat lovande framsteg i detta utmanande område. I detta arbete är målet att förutsäga inkapslande 3D-lådor från en bild utan användning av temporal data eller explicit beräkning av djup. Tillvägagångssättet vi föreslår för 3D monokulär objektsdetektion baseras på Deep3DBox. Vårt mål är att ersätta de geometriska gränserna som har använts för förutsägning av 3D-position med en djupinlärningsmodul. Dessutom genomför vi en studie på olika modulparametrar som används för förutsägelse av dimension och orientering av objekt. Vi gör experiment för att finna de bästa hyperparametrarna för vår model för KITTI-bilar och vi rapporterar och jämför våra resultat med KITTI och NuScenes utmanande riktmärken för bilar och fotgängare med andra toppresterande metoder. Vi kan därför dra slutsatsen att vårt tillvägagångssätt presterar likvärdigt med liknande metoder och förbättrar Deep3DBox-resultaten.

Résumé :

In this thesis a quadrotor is studied and a linear model is derived using grey-box estimation, a discipline in system identification where a model structure based on physical relations is used and the parameters are estimated using input-output measurements. From IMU measurements and measured PWM signals to the four motors, a direct approach using the prediction-error method is applied. To investigate the impact of the unknown controller the two-stage method, a closed-loop approach in system identification, is applied as well. The direct approach was enough for estimating the model parameters. The resulting model manages to simulate the major dynamics for the vertical acceleration and the angular rates well enough for future control design.

Résumé :

There are many names or labels which refer to the generation growing up with digital media and these include labels such as ‘Net Generation’ (Tapscott, 1998), ‘digital natives’ (Prensky, 2001), ‘cyberkids’ (Holloway, 2003) and ‘MySpacegeneration’ (Rosen, 2008). The core idea behind these labels is that young people who have grown up surrounded by digital technology are very different to previous generations in their way of using and even thinking about the new digital technology. This appears to be reinforcing a generational divide and makes the assumption that young people can be categorized into one group in relation to their use of ICTs. The approach in this thesis is to empirically explore, in order to nuance, some of these presumptions about the ‘Net Generation’ (defined according to Tapscott). Thus, the research question is: How can the presumptions about the ‘Net Generation’ be nuanced? The following three presumptions have been explored within the three papers included in the thesis: i) The ‘Net Generation’ diverges from previous generations in relation to the use of internet; ii) The ‘Net Generation’ is techno-savvy or digitally competent; iii) The digitally competent ‘Net Geners’ are also digital participants since there is a causal relationship between digital competence and digital participation. The explorations are conducted by using the theoretical concepts ‘digital skills’, ‘self-efficacy’ and ‘participatory culture’. Several hypotheses,deduced from previous research, have been tested on a national representative sample of people born between the years 1978 and 1997 (categorised as the ‘Net Generation’). The results show that ‘Net Geners’ internet usage is diversified;hence, it is simplified to talk about them as a homogeneous group. Those included in the categorisation have different opportunities to participate in the digital society. Their internet usage differs both in terms of how much time they spend and what they do online. Their digital skills and self-efficacy in the use of computers are also different and so is the perceived feeling of participation in the information society. This implies that the ‘Net Geners’ do not have equal conditions in relation to participation in the digital society. However, what is meant by participation is still an unresolved question which requires further exploration.
SAMMANDRAG Idag beskrivs ofta generationen som vuxit upp med internet och digitala medier i termer av att vara en ”internetgeneration” (Tapscott, 1998), "digitala infödingar" (Prensky, 2001), "cyberkids" (Holloway, 2003) eller "MySpace-generation" (Rosen, 2008). Dessa antaganden bygger på att det finns en generationsskillnad i förhållningssätt till internet, d.v.s. att ”internetgenerationen” är de som är kunniga och vana internetanvändare till skillnad från äldre generationer som inte helt naturligt kan ta till sig den nya digitala tekniken. Avhandlingens syfte är att empiriskt undersöka ett antal antaganden om ”internetgenerationen” för att ta reda hur dessa kan nyanseras. Således är frågeställningen: Hur kan antaganden om "internetgenerationen" nyanseras? Följande tre antaganden har utforskats inom de tre artiklarna som ingår i avhandlingen: i) "internetgenerationen" skiljer sig från tidigare generationer när det gäller användningen av internet, ii) "internetgenerationen" är tekniskt kunniga eller digitalt kompetenta; iii) den digitalt kompetenta "internetgenerationen" är också digitalt delaktig eftersom det finns ett orsakssamband mellan digital kompetens och digital delaktighet. För att empiriskt undersöka antagandena om internetgenerationen har teoretiska koncept så som ”digital skills”, ”self-efficacy” samt ”participatory culture” använts. Ett antal hypoteser som deducerats utifrån tidigare forskning har testats på ett riksrepresentativt urval av personer födda mellan 1978 och 1997 (de som tillhör internetgenerationen). Resultaten visar att det är en förenklad bild att prata om en internetgeneration. De som ingår i den kategoriseringen har olika förutsättningar att delta i det digitala samhället. Deras internetanvändning skiljer sig åt både när det gäller hur mycket tid de spenderar samt vad de gör online. Deras digitala kompetens och självförtroende när det gäller användning av datorer skiljer sig också åt och det gäller även den upplevda känslan av delaktighet i informationssamhället. Detta indikerar att inte alla har samma förutsättningar att vara delaktiga i det digitala samhället. Vad som däremot innebär att vara delaktig är fortfarande en obesvarad fråga som behöver ägnas mer uppmärksamhet i framtida studier.

Résumé :

Active safety systems for automobiles in the form of camera systems have evolved rapidly the last ten years, Autoliv Electronics in Linköping develops multiple such systems. In their development process there is a need for a Break out Box (BoB) to record and playback video and CAN data as if the camera system was used in an actual automobile. The aim of this thesis has been to develop a BoB for these camera systems. The work has been divided into three phases; identiﬁcation of requirements, design of the BoB and implementation of a prototype. The project has addressed four known issues with the currently used BoB; bandwidth, modularity, synchronization and usability. The result is a new BoB which is based on an FPGA connecting to a PC over Gigabit Ethernet. The design is an extendible platform for multiple channels of video, CAN data, other serial data and future extensions. A prototype proves the design concept by successfully recording video for the Autoliv NightVision system onto a PC.

Résumé :

In the development of digitally connected solutions that require the use of personal data, the issue of data privacy is an important factor that must be taken into account. Simply informing users about how data is used and getting their consent with a simple click is not enough to create awareness of the issue of data privacy and let them make a conscious decision about the use of their personal data. Furthermore, there is a big gap in knowledge about what personal data is and what is considered sensitive data. Especially the knowledge about what biometric identifiers that they are used in a variety of everyday life applications and in which sense the handling can be problematic is unknown.This thesis project explores how the use of critical play in form of an activist game can create awareness of the issue of data privacy, inform about the value of biometric data and foster self-reflection of handling one’s own personal data. Through the simulation of dependencies between personal data, the motivation to share them and the aggregation of personal data in combination with real and prospective use cases, players are empowered to reflect on their behaviour and to critically deal with the topic of data privacy.

This word aimeded to develop a friendly computational tool that, given the expectation of the producer in relation to soybean prices at a future date, help them decide whether or not it‟s worth waiting to sell their produce at that future date or sell in the current date. This work relied mainly with the System Dynamics methodology for model building and testing of Box-Jenkins to obtain the price expectations. The model also allows deriving the likely minimum price to be received by the producer in order to justify its decision to postpone its sale. We found no empirical evidence capable of sustaining the existence of a priori a better time to sell soybeans.

Para tanto, contou principalmente com a metodologia System Dynamics para construção do modelo e a análise de Box-Jenkins para obtenção das expectativas de preços. O modelo desenvolvido, também, permite auferir o provável preço mínimo a ser recebido pelo produtor, a fim de que possa justificar sua decisão em postergar sua venda. Não foram encontradas evidências empíricas capazes de sustentar a existência a priori de uma melhor data para se vender a soja.

Résumé :

This study takes one step further towards constructing a tool able to automatically amplify the security on your cryptographic implementations. In white box cryptography the encryption key is hidden inside the encryption algorithm out of plain sight. An attacker can try to extract the secret key by conducting a side channel attack, differential computational analysis, which many white boxes are vulnerable to. The technique to increase security explored in this study consists of randomly with different probabilities perturb the white box by adding the value one to a variable inside the running white box. This does break the correctness of the output on all the three tested white box implementations to various extents, but some perturbations can be made which maintains fairly high correctness on the output of the program. Running a white box with perturbations does not cause any significant increase in execution time. Out of more than 100 000 possible perturbation points 25 were chosen to be investigated further. In one case the security of a perturbed white box increased, but in four similar cases the white box was made more insecure, otherwise no change in security was observed. A more sophisticated technique of identifying the best point to insert perturbations are therefore required in order to further investigate how to increase the security of your cryptographic implementations while still maintaining a fairly high correctness despite the program experiencing random perturbations.
Denna studie tar ett steg längre i att skapa ett verktyg som automatiskt höjer säkerheten på kryptografiska implementationer. I white box-kryptografi är krypteringsnyckeln som används redan gömd inuti den valda krypteringsalgoritmen. En användare med onda intentioner kan vilja försöka att extrahera denna gömda krypteringsnyckel genom att utföra en typ utav side-channel -attack, differential computational analys, vilket flera white box-implementationer är sårbara för. Tekniken för att öka säkerheten hos dessa white box-implementationer som utforskas i denna studie går ut på att slumpmässigt, med olika sannolikheter störa white box-implementationen genom att addera värdet ett (1) till en godtycklig variabel mitt under programmets körning. Detta sänker korrektheten på outputen från alla de tre testade white box-implementationerna olika mycket, men vissa störningar kan utföras och fortfarande resultera i hög korrekthet. Att sätta in sådana störningar i white box-implementationerna har ingen större inverkan på dess totala exekveringstid. Utav 100 000 möjliga ställen att sätta in en störning på valdes 25 utav dessa att undersökas vidare. I ett utav dessa fall ökade säkerheten på white box-implementationen, men i fyra liknande fall minskade säkerheten, annars på övriga störningspunkter fanns det inga tecken på en förändring i säkerhet. Ett mer sofistikerat sätt att identifiera de bästa störningspunkterna på behöver därför utredas för att bygga vidare på detta arbete med att öka säkerheten hos kryptografiska implementationer genom att utsätta dem för slumpmässiga störningar och samtidigt kunna hålla hög korrekthet i programmets resultat.

Résumé :

Software testing is an important and time consuming part of the software development cycle. While automated testing frameworks do help in reducing the amount of programmer time that testing requires, the onus is still upon the programmer to provide such a framework with the inputs upon which the software must be tested. This requires static analysis of the source code, which is more effective when performed as a peer review exercise and is highly dependent on the skills of the programmers performing the analysis. It also demands the allocation of precious time for those very highly skilled programmers. An algorithm that automatically generates inputs to satisfy test coverage criteria for the software being tested would therefore be quite valuable, as it would imply that the programmer no longer needs to analyze code to generate the relevant test cases. This thesis explores a hybrid evolutionary strategy with an evolutionary algorithm to discover such test cases , in an improvement over previous methods which overly focus their search without maintaining the diversity required to cover the entire search space efficiently.

Résumé :

Software testing is a part of software development process. However, this part is the first one to miss by software developers if there is a limited time to complete the project. Software developers often finish their software construction closed to the delivery time, they usually don¿t have enough time to create effective test cases for testing their programs. Creating test cases manually is a huge work for software developers in the rush hours. A tool which automatically generates test cases and test data can help the software developers to create test cases from software designs/models in early stage of the software development (before coding). Heuristic techniques can be applied for creating quality test data. In this paper, a GA-based test data generation technique has been proposed to generate test data from UML state diagram, so that test data can be generated before coding. The paper details the GA implementation to generate sequences of triggers for UML state diagram as test cases. The proposed algorithm has been demonstrated manually for an example of a vending machine.

Texte intégral

Résumé :

In this thesis the effect of normalization methods on the identification of differentially expressed genes is investigated. A zebrafish microarray dataset called Swirl was used in this thesis work. First the Swirl dataset was extracted and visualized to view if the robust spline and print tip loess normalization methods are appropriate to normalize this dataset. The dataset was then normalized with the two normalization methods and the differentially expressed genes were identified with the LimmaGUI program. The results were then evaluated by investigating which genes overlap after applying different normalization methods and which ones are identified uniquely after applying the different methods. The results showed that after the normalization methods were applied the differentially expressed genes that were identified by the LimmaGUI program did differ to some extent but the difference was not considered to be major. Thus the main conclusion is that the choice of normalization method does not have a major effect on the resulting list of differentially expressed genes.

Texte intégral

Résumé :

This thesis evaluates and shows an implementation of a video telephony solution for network connected set-top boxes based on the SIP protocol for managing sessions.

Unlike other video telephony implementations the set-top box does not handle both audio and video, but only video. A separate phone is used to handle audio. To maintain compatibility with other video telephony implementations, which expect a single SIP device with both audio and video capabilities, a mechanism to merge the audio (SIP-phone) and video (set-top box) into a single entity was developed using a back-to-back user agent.

Due to the set-top boxes'limited hardware it could be impossible to have video compression and decompression performed by the set-top boxes. However, numerous performance tests of compression algorithms showed that the computational power available in the set-top boxes is sufficient to have acceptable frame rate and image quality in a video telephony session. A faster CPU or dedicated hardware for video compression and decompression would however be required in order to compete with dedicated video telephony systems available today.

The implemented video telephony system is based on open standards such as SIP, RTP and H.261, which means interoperability with other video telephony implementations, such as Microsoft's Windows Messenger 4.7, is good.

Résumé :

A city consists of many elements such as humans, buildings, and roads. The complexity of cities is difficult to measure using Euclidean geometry. In this study, we use fractal geometry (scaling analysis) to measure the complexity of urban areas. We observe urban development from different perspectives using the bottom-up approach. In a bottom-up approach, we observe an urban region from a basic to higher level from our daily life perspective to an overall view. Furthermore, an urban environment is not constant, but it is complex; cities with greater complexity are more prosperous. There are many disciplines that analyze changes in the Earth’s surface, such as urban planning, detection of melting ice, and deforestation management. Moreover, these disciplines can take advantage of remote sensing for research. This study not only uses satellite imaging to analyze urban areas but also uses check-in and points of interest (POI) data. It uses straightforward means to observe an urban environment using the bottom-up approach and measure its complexity using fractal geometry. Web 2.0, which has many volunteers who share their information on different platforms, was one of the most important tools in this study. We can easily obtain rough data from various platforms such as the Stanford Large Network Dataset Collection (SLNDC), the Earth Observation Group (EOG), and CloudMade. The check-in data in this thesis were downloaded from SLNDC, the POI data were obtained from CloudMade, and the nighttime lights imaging data were collected from EOG. In this study, we used these three types of data to derive natural cities representing city regions using a bottom-up approach. Natural cities were derived from open geographic data without human manipulation. After refining data, we used rough data to derive natural cities. This study used a triangulated irregular network to derive natural cities from check-in and POI data. In this study, we focus on the four largest US natural cities regions: Chicago, New York, San Francisco, and Los Angeles. The result is that the New York City region is the most complex area in the United States. Box-counting fractal dimension, lacunarity, and ht-index (head/tail breaks index) can be used to explain this. Box-counting fractal dimension is used to represent the New York City region as the most prosperous of the four city regions. Lacunarity indicates the New York City region as the most compact area in the United States. Ht-index shows the New York City region having the highest hierarchy of the four city regions. This conforms to central place theory: higher-level cities have better service than lower-level cities. In addition, ht-index cannot represent hierarchy clearly when data distribution does not fit a long-tail distribution exactly. However, the ht-index is the only method that can analyze the complexity of natural cities without using images.

Costas loop is a well known method and is the basis in the design of the BPSK demodulation. A new design approach employing digital Box Car arm filters is used to improve receiver performance and flexibility. Detail design and performance of the digital Costas loop will be explored in a later section. A classical technique is employed for Phase demodulation with the use of tracking Phase Lock Loop. Frequency demodulation is designed around a simple, single FM discriminator IC.

Résumé :

Many models have been proposed for software reliability prediction, but none of these models could capture a necessary amount of software characteristic. We have proposed a mixed approach using both analytical and data driven models for finding the accuracy in reliability prediction involving case study. This report includes qualitative research strategy. Data is collected from the case study conducted on three different companies. Based on the case study an analysis will be made on the approaches used by the companies and also by using some other data related to the organizations Software Quality Assurance (SQA) team. Out of the three organizations, the first two organizations used for the case study are working on reliability prediction and the third company is a growing company developing a product with less focus on quality. Data collection was by the means of interviewing an employee of the organization who leads a team and is in the managing position for at least last 2 years.

Résumé :

The final thesis focuses on the issue of analyzing the situation of a citizen in connection with a services of the public administration. One of the main goals is to acquaint the reader with the services of the public administration, with the concept of eGovernment and provide a comparison of this area with other countries. These objectives are achieved by studying resources relating to Czech and foreign eGovernment and they are given to the theoretical part. The practical part is devoted to the specific life situations (services) within communication between citizen and public administration. These services were analyzed through a defined methodology to determine the level of friendliness in relation to the user and if necessary, make recommendations for improvement. The main part is devoted to the data box. The reader learns how to set up and activate the data box, what level the user interface is and what functionality can be used in connection with the data box. Benefit of this work is to familiarize the reader with the eGovernment projects in the Czech Republic. Another benefit is to familiarize the reader with the data box to levels that he will be able to use it.

The objective of this work was to verify the efficiency of Box-Cox and Blom scores transformations in correcting the phenotypic heterogeneity of variance adjusted weights of cattle Tabapuã the Brazilian Northeast to the factors producing regions, ages and sex. We used data Tabapuã the Brazilian Northeast, collected from 1970, from the control of weight development Brazilian Association of Zebu Breeders (ABCZ) with information concerning the weights adjusted to 205, 365 and 550 days of age. The Box-Cox and Blom scores transformations were used in an attempt to correct the heterogeneity of variances for the factors of production regions, ages and sex. Bartlett's test was applied before and after the transformation of the data to see if there was a reduction of heterogeneity of phenotypic variances. The Blom scores transformation was effective in reducing the coefficients of skewness and kurtosis and was more appropriate than the Box-Cox transformation to correct the phenotypic heterogeneity of variance between production regions, ages and sex, since produced significantly more favorable results.
O objetivo deste trabalho foi verificar a eficiência das transformações de Box- Cox e escores de Blom na correção da heterogeneidade de variâncias fenotípicas dos pesos ajustados de bovinos da raça Tabapuã do Nordeste brasileiro para os fatores regiões de produção, idades e sexos. Foram utilizados dados da raça Tabapuã do Nordeste brasileiro, coletados a partir de 1970, provenientes do controle de desenvolvimento ponderal da Associação Brasileira de Criadores de Zebuíno (ABCZ) com informações relativas a pesos ajustados para 205, 365 e 550 dias de idade. As transformações em escores de Blom e Box-Cox foram utilizadas na tentativa de corrigir a heterogeneidade de variâncias para os fatores regiões de produção, idades e sexos. O teste de Bartlett foi aplicado antes e após a transformação dos dados para verificar se houve redução da heterogeneidade de variâncias fenotípicas. A transformação em escores de Blom foi efetiva na redução dos coeficientes de assimetria e curtose e mostrou-se mais adequada do que a transformação de Box-Cox para correção da heterogeneidade de variâncias fenotípicas entre regiões de produção, idades e sexos, uma vez que apresentou um maior número de resultados favoráveis.

Résumé :

This thesis covers design and implementation of a media system solution for home networks with personal computers and a set-top box.

In a home there are effectively two independent media systems with the same purpose: the personal computer and the digital set-top box, with the purpose of delivering digital media in form of audio and video to the consumer.

The goal of the thesis work was to implement a solution that bridges the gap between the two systems, so that the user, from the set-top box, can play back media that is actually stored on one or several personal computers.

Our solution is based on UPnP technology, which is used for service discovery and control. The choice of UPnP is motivated by an evaluation of discovery protocols, which concludes that UPnP is the most suitable technology in this particular system. Also, an evaluation of suitable transport protocols was done. Here,HTTP was used.

For the personal computer, a media server and a graphical user interface for configuring the media server were created. For the set-top box, a media client, and a graphical user interface for browsing the content of the media server, were created. In conclusion, the creation of the prototype was successful and the set-top box was able to playback media that had been shared by the PC on the network.

Résumé :

Depuis la publication en 1999 du papier fondateur de Paul C. Kocher, Joshua Jaffe et Benjamin Jun, intitulé "Differential Power Analysis", les attaques par canaux auxiliaires se sont révélées être un moyen d’attaque performant contre les algorithmes cryptographiques. En effet, il s’est avéré que l’utilisation d’information extraite de canaux auxiliaires comme le temps d’exécution, la consommation de courant ou les émanations électromagnétiques, pouvait être utilisée pour retrouver des clés secrètes. C’est dans ce contexte que cette thèse propose, dans un premier temps, de traiter le problème de la réduction de dimension. En effet, en vingt ans, la complexité ainsi que la taille des données extraites des canaux auxiliaires n’a cessé de croître. C’est pourquoi la réduction de dimension de ces données permet de réduire le temps et d’augmenter l’efficacité des attaques. Les méthodes de réduction de dimension proposées le sont pour des modèles de fuites complexe et de dimension quelconques. Dans un second temps, une méthode d’évaluation d’algorithmes logiciels est proposée. Celle-ci repose sur l’analyse de l’ensemble des données manipulées lors de l’exécution du logiciel évalué. La méthode proposée est composée de plusieurs fonctionnalités permettant d’accélérer et d’augmenter l’efficacité de l’analyse, notamment dans le contexte d’évaluation d’implémentation de cryptographie en boîte blanche
Since the publication in 1999 of the seminal paper of Paul C. Kocher, Joshua Jaffe and Benjamin Jun, entitled "Differential Power Analysis", the side-channel attacks have been proved to be efficient ways to attack cryptographic algorithms. Indeed, it has been revealed that the usage of information extracted from the side-channels such as the execution time, the power consumption or the electromagnetic emanations could be used to recover secret keys. In this context, we propose first, to treat the problem of dimensionality reduction. Indeed, since twenty years, the complexity and the size of the data extracted from the side-channels do not stop to grow. That is why the reduction of these data decreases the time and increases the efficiency of these attacks. The dimension reduction is proposed for complex leakage models and any dimension. Second, a software leakage assessment methodology is proposed ; it is based on the analysis of all the manipulated data during the execution of the software. The proposed methodology provides features that speed-up and increase the efficiency of the analysis, especially in the case of white box cryptography

Résumé :

IT equipment has been estimated to be responsible for 2% of global CO2 emissions and data centers are responsible for 1.2% of U.S. energy consumption. With the large quantity of high quality digital content available on the Internet the energy demands and environmental impact of the data centers must be addressed. The use of peer-to-peer technologies, such as BitTorrent, to distribute legal content to consumers is actively being explored as a means of reducing both file download times and the energy consumption of data centers. This approach pushes the energy use out of the data centers and into the homes of content consumers (who are also then content distributors). The current BitTorrent protocol requires that clients must be fully powered-on to be participating members in a swarm. In this thesis, an extension to the BitTorrent protocol that utilizes long-lived knowledge of sleeping peers to enable clients to sleep when not actively distributing content yet remain responsive swarm members is developed. New peer states and events required for the protocol extension, the implementation the new protocol in a simulation environment, and the implementation of the protocol extension in a real client are described. Experiments on a simulated swarm of 51 peers transferring a 1 GB and a real swarm of 11 peers transfer- ring a 100 MB file were run. To validate the simulation a simulated swarm of 11 peers transferring a 100 MB file is compared to the real swarm of 11 peers. The results of standard BitTorrent are compared to the new Green BitTorrent by examining download times, sleep time, and awake time. The results of the experiment show significant energy savings are possible with only a small penalty in download time. Energy savings of up to 75% are shown with download time increases as little as 10%. These energy savings could equate to over $1 billion dollars per year in the US alone if Green BitTorrent is used instead of standard BitTorrent for future rollouts of legal distribution systems.

Résumé :

This work addresses the issue of data boxes information system, which supports electronic communication between public authorities and other bodies. Aim of the work is to identify measure and evaluate the effectiveness of the data boxes at selected public authorities when processing received and sent documents. The effectiveness is detected by using the proposed metrics and also based on the analysis conducted in order to examine the processing of documents at selected institutions. The effectiveness of data boxes is being researched at the Municipal Office Dub nad Moravou and the Czech Agriculture and Food Inspection Authority. The information needed for the process analysis and the data required for evaluating the effectiveness of the implementation of the proposed metrics were obtained from the staff of those institutions. The work is divided into four parts. The first part is a thorough description of the data boxes information system. The functionality, use, technical solutions and legislations of data boxes are described based on available information. The second part focuses on the description and analysis of selected public authorities and on the way they process received and outgoing mail. In the third part of the work appropriate metrics to assess the effectiveness of the data boxes are proposed, followed by implementation of two-phase measurements. In the fourth section the effectiveness of the data boxes is evaluated based on the measurements conducted at selected public authorities. The main contribution of this work is that it will be the first evaluation of the effectiveness of the data boxes in selected subjects approximately one month after the official launch. Another benefit is the proposal of process for the evaluation of the effectiveness of a very specific new information system within the body and a comprehensive description of the data boxes information system.

Dengue é uma doença infecciosa que afeta países subtropicais. Autoridades de saúde locais utilizam informações sobre o número de notificações para monitorar e prever epidemias. Este trabalho foca na modelagem do número de casos de dengue semanal em quatro cidades do estado do Rio de Janeiro: Rio de Janeiro, São Gonçalo, Campos dos Goytacazes, e Petrópolis. Modelos de séries temporais são frequentemente utilizados para prever o número de casos de dengue nos próximos ciclos (semanas ou meses), particularmente, modelos SARIMA (Modelo Sazonal Autorregressivo Integrado de Médias Móveis) apresentam uma boa performance em situações distintas. Modelagens alternativas ainda incluem informação sobre o clima da região para melhorar a performance preditiva. Apesar disso, modelos que usam apenas dados históricos e de clima podem não possuir informações suficientes para capturar mudanças entre os regimes de não-epidemia e epidemia. Duas razões para isso são o atraso na notificação dos casos e que possivelmente não houveram epidemias nos anos anteriores. Baseando-se no sistema de monitoramento InfoDengue, esperasse que incluindo dados sobre ”numero de reprodução efetiva dos mosquitos”(RT) e ”número de tweets se referindo a dengue”(tweets) possam melhorar a qualidade das previsões no curto (1 semana) e longo (8 semanas) prazo. Foi possível mostrar que modelos de séries temporais incluindo RT e informações climáticas frequentemente performam melhor do que o modelo SARIMA em termos do erro preditivo quadrático médio (RMSE). Incluir a variável sobre o twitter não mostrou uma melhora no RMSE.
Dengue fever is an infectious disease affecting subtropical countries. Local health departments use the number of notified cases to monitor and predict epidemics. This work focus on modeling weekly incidence of dengue fever in four cities of the state of Rio de Janeiro: Rio de Janeiro, São Gonçalo, Campos dos Goytacazes, and Petrópolis. Time series models are often used to predict the number of cases in the next cycles (weeks, months), in particular, SARIMA (Seazonal Auto-Regressive Integrated Moving Average) models are shown to perform well in distinct settings. Alternative models also include climate covariates to improve the quality of the forecasts. However, models that only use historical and climate data may no have sufficient information to capture changes from non-epidemic to an epidemic regime. Two reasons are that there is a delay in the notification of cases and there might not have had epidemics in the previous years. Based on the INFODENGUE monitoring system we argue data including the "effective reproduction number of mosquitoes" (RT) and "number tweets referring to dengue" (tweets) may improve the quality of forecasts in the short (1 week) to long (8 weeks) range. We show that time series models including RT and climate information often outperform SARIMA models in terms of mean squared predictive error (RMSE). Inclusion of twitter did not improve the RMSE.

Résumé :

Cloud computing and cloud storage services, in particular, pose a new challenge to digital forensic investigations. Currently, evidence acquisition for such services still follows the traditional approach of collecting artifacts on a client device. In this work, we show that such an approach not only requires upfront substantial investment in reverse engineering each service, but is also inherently incomplete as it misses prior versions of the artifacts, as well as cloud-only artifacts that do not have standard serialized representations on the client. In this work, we introduce the concept of API-based evidence acquisition for cloud services, which addresses these concerns by utilizing the officially supported API of the service. To demonstrate the utility of this approach, we present a proof-of-concept acquisition tool, kumodd, which can acquire evidence from four major cloud storage providers: Google Drive, Microsoft One, Dropbox, and Box. The implementation provides both command-line and web user interfaces, and can be readily incorporated into established forensic processes.

Résumé :

The diploma thesis deals with the processes associated with receiving and sending postal items of E.ON Czech Republic followed with the effective development of the life cycle of documents with use of the digitization and data mining. The aim is to develop the project "Electronic Registry", which can be implemented into current information systems of the company and which will contribute to the optimization of processes of the registry. To achieve this objective it was developed an extensive analysis of the current state of registry and records management system in E.ON Czech Republic. Based on analysis it was proposed a specific solution for improvement. The first part deals with the analysis of current legislative requirements and theoretical analysis of the document lifecycle, which is demonstrated on the example of E.ON Czech Republic in the second part of the thesis. In the second part there is the introduction of company E.ON Czech Republic, which is followed by description of the current state of registry and processes in relation to the rece-iving of postal items. In the analysis of the current situation there are identified issues that arise when receiving and processing postal items to the registry. To the identified problems are offered individual solutions, which are elaborated in the overall solution in the final part of the thesis. The last part is a custom suggestion of optimization of existing processes by using of digi-tizing paper documents and data mining for automatic sorting, which helps to streamline existing processes. This section describes specific solution that is introduced into the E.ON Czech Republic. The solution system provides a single place for the digitization of docu-ments received and their subsequent management.

Résumé :

The rapid development of technology in the health-care sector has led to the discovery of many new illnesses and improved treatments that were not possible earlier. However, many treatments and medicines for a specific disease often come with several side effects. The accuracy in treatments with an optimal result on specified targets is therefore desired with minimum side effects. This requires that the production and the usage processes should be precise. The scope of this study is not about the medicine production phase but rather on managing a medicine schedule. How many times a medicine should be taken in a day is strongly related to its dosage and following a precise timing plays a crucial role in the individual’s health. As a solution, a pill box based on a low power display (Electronic Paper Display, EPD) together with an embedded system has been introduced by the project owner (Victrix AB, Stockholm) .The pill box should have some different functions like alarms, data logging and wireless reporting. Different types of alarms including ringtone, vibration and voice recording/playing are required as well. To be able to trace the already planned timing for taking medicines, system will be able to save and report history of the past 100 days. Since every single idea for solving different parts of the problem should be tested in real system, a Quantitative Research based on experiments be used and the best possible solution be selected and implemented in the project. Studying technical material and also related works besides analyzing generated data after each experiment were a useful tool for the system integration in this work. As the result, a pill box based on an embedded system was designed and integrated successfully. A hardware platform, in form of a prototype system based on an ARM microcontroller and a compatible embedded software have been designed, improved and tested successfully and are available. At the end of this work, the low power E-paper display works properly, alarms can be set and activated, data can be saved and also sent wirelessly. Basically, the result of this project shows how an embedded system can be specialized and programmed to be able to interact with patients and e.g. nurses in order to make a stable and continuous connection between them. Most of determined goals have been achieved and some of them be changed and modified during the work. Also a few additional functions and improvements be suggested as future work.

Résumé :

Machine learning models are becoming more and more powerful and accurate, but their good predictions usually come with a high complexity. Depending on the situation, such a lack of interpretability can be an important and blocking issue. This is especially the case when trust is needed on the user side in order to take a decision based on the model prediction. For instance, when an insurance company uses a machine learning algorithm in order to detect fraudsters: the company would trust the model to be based on meaningful variables before actually taking action and investigating on a particular individual. In this thesis, several explanation methods are described and compared on multiple datasets (text data, numerical), on classification and regression problems.
Maskininlärningsmodellerna blir mer och mer kraftfulla och noggranna, men deras goda förutsägelser kommer ofta med en hög komplexitet. Beroende på situationen kan en sådan brist på tolkning vara ett viktigt och blockerande problem. Särskilt är det fallet när man behöver kunna lita på användarsidan för att fatta ett beslut baserat på modellprediktionen. Till exempel, ett försäkringsbolag kan använda en maskininlärningsalgoritm för att upptäcka bedrägerier, men företaget vill vara säkert på att modellen är baserad på meningsfulla variabler innan man faktiskt vidtar åtgärder och undersöker en viss individ. I denna avhandling beskrivs och förklaras flera förklaringsmetoder, på många dataset av typerna textdata och numeriska data, på klassificerings- och regressionsproblem.

Résumé :

When developing HTML5 applications for TV platforms, the TV platforms provide, in addition to standardHTML5 functionality, also extra APIs for TV-specific features. These extra APIs differ between TVplatforms, and that is a problem when developing an application targeting several platforms. This thesis hasexamined if it is possible to design a framework which provides the developer with one API that works formany platforms by wrapping their platform-specific code. The answer is yes. With success, platform-specificfeatures including: TV remote control input, video, volume, Internet connection status, TV channel streamsand EPG data have been harmonised under an API in a JavaScript library. Furthermore, a build systempackages the code in the way the platforms expect. The framework eases the development of TV platformHTML5 applications. At the moment, the framework supports the Pace, PC and Samsung Smart TVplatforms, but it can be extended with more TV platform back-ends.
Lorsque l’on développe des applications HTML5 pour des plateformes TV, les plateformes TV fournissent,en plus de la fonctionnalité standard d'HTML5, des APIs supplémentaires pour les particularités d'une TV.Ces APIs supplémentaires diffèrent entre les plateformes TV, et ceci cause un problème lors dudéveloppement d’une application pour plusieurs plateformes. Cette thèse a fait l’examen de la possibilité deconcevoir un cadre d'applications qui fournit au concepteur une API qui peut servir à plusieurs plateformes,cachant le code spécifique de celles-ci. La réponse est oui. On a réussi à harmoniser : l’entrée de latélécommande, le lecteur vidéos, le volume, la connexion Internet, le flux TV et leurs données GPE, dans uneAPI qui réside dans une bibliothèque JavaScript. En outre, un système de compilation met le code d’unemanière dont la plateforme peut comprendre. Le cadre d'applications facilite le développement d'applicationsHTML5 des plateformes TV. Pour le moment, le cadre d'applications peut supporter la Pace, le PC et laplateforme de Samsung Smart TV, mais il peut également fonctionner avec d'autres plateformes TV.
Wenn man HTML5-Anwendungen für TV-Plattformen entwickelt, stellen die Plattformen neben denStandardfunktionalitäten von HTML5 auch extra APIs für TV spezifische Features zur verfügung. Diesezuzätzlichen APIs unterscheiden zwischen TV-Plattformen und das ist ein Problem bei der Entwicklung vonAnwendungen, die auf mehreren Plattformen laufen sollen. Diese These untersucht, ob es möglich ist, einFramework zu entwerfen, dass dem Entwickler eine API bereitstellt, welche für mehrere Plattformenfunktioniert, indem deren Plattform spezifischer Code verpackt wird. Die Antwort ist ja. Das Frameworkharmonisiert: Fernbedienungeingabe, Video, Volumen, Internet-Anschlussstatus, Fensehkanalstreams undelektronische Programmführer, zu einer gemeinsamen JavaScript-Bibliothek-API. Weiterhin verpackt einbuild system den Code so, wie es die Plattform erwartet. Das Framework erleichtert die Entwicklung vonHTML5-Applikationen für TV-Plattformen. Im Moment deckt das Framework: Pace-, PC- und SamsungSmart TV-Plattformen, aber es kann mit weiteren TV-Plattformen erweitert werden.
Quando si sviluppano delle applicazioni HTML5 per le piattaforme TV, quest'ustime offrono, oltre allafunzionalità comune di HTML5, anche APIs addizionali per funzionalità specifiche della TV. Queste APIsaddizionali differiscono tra le varie piattaforme TV e questo è un problema quando si sviluppaun'applicazione che funzioni per ciascuna piattaforma. Il presente lavoro esamina la possibilità di progettareun framework che fornisca allo sviluppatore una sola API, la quale sia funzionante per molte piattaforme esia idonea a nascondere il codice specifico di ciascuna di esse. La risposta è sì. Il framework fonde:l'immissione del telecomando, il video, il volume, lo stato della connessione Internet, i flussi dei canali TV edei dati della guida elettronica dei programmi, all'interno di una API secondo il modello di una libreriaJavaScript. Inoltre, il sistema di compilazione crea un pacchetto del codice nel modo in cui le piattaforme siaspettano. Il framework facilita lo sviluppo di applicazioni HTML5 per le piattaforme TV. Al momento, ilframework sostiene le seguenti piatteforme: Pace, PC e Samsung Smart TV, ma può essere esteso anche adaltre.
När man utvecklar HTML5-applikationer för TV-plattformar, finns utöver HTML5s standardfunktionalitet,även extra APIer för att komma åt TV-specifika funktioner. Dessa extra APIer skiljer sig åt mellan TV-plattformar, och det är ett problem när man utvecklar en applikation för många plattformar. Dettaexamensarbete har undersökt om det är möjligt att designa ett ramverk som förser utvecklaren med ett APIsom fungerar för många plattformar genom att wrappa deras plattformsspecifika kod. Svaret är ja. Ramverketharmoniserar: fjärrkontrollsindata, video, volym, internetförbindelse, TV-kanalströmmar och deras TV-tablåer, till ett gemensamt JavaScript-bibliotek-API. Vidare paketerar ett byggsystem koden på de sätt somplattformarna förväntar sig. Ramverket underlättar utveckling av HTML5-applikationer för TV-plattformar.För tillfället stöder ramverket plattformarna: Pace, PC och Samsung Smart TV, men det kan breddas med flerTV-plattformar.

Résumé :

To determine whether a credit limit for a corporate client should be changed, a financial institution writes a PM containingtext and financial data that then is assessed by a credit committee which decides whether to increase the limit or not. To make thisprocess more efficient, machine learning algorithms was used to classify the credit PMs instead of a committee. Since most machinelearning algorithms are black boxes, the LIME framework was used to find the most important features driving the classification. Theresults of this study show that credit memos can be classified with high accuracy and that LIME can be used to indicate which parts ofthe memo had the biggest impact. This implicates that the credit process could be improved by utilizing machine learning, whilemaintaining transparency. However, machine learning may disrupt learning processes within the organization.
För att bedöma om en kreditlimit för ett företag ska förändras eller inte skriver ett finansiellt institut ett PM innehållande text och finansiella data. Detta PM granskas sedan av en kreditkommitté som beslutar om limiten ska förändras eller inte. För att effektivisera denna process användes i denna rapport maskininlärning istället för en kreditkommitté för att besluta om limiten ska förändras. Eftersom de flesta maskininlärningsalgoritmer är svarta lådor så användes LIME-ramverket för att hitta de viktigaste drivarna bakom klassificeringen. Denna studies resultat visar att kredit-PM kan klassificeras med hög noggrannhet och att LIME kan visa vilken del av ett PM som hade störst påverkan vid klassificeringen. Implikationerna av detta är att kreditprocessen kan förbättras av maskininlärning, utan att förlora transparens. Maskininlärning kan emellertid störa lärandeprocesser i organisationen, varför införandet av dessa algoritmer bör vägas mot hur betydelsefullt det är att bevara och utveckla kunskap inom organisationen.

Résumé :

Clinical trials are experiments or observations on a patient’s responses of different medical treatments to cure diseases. Such trials are heavily regulated and must achieve a certain quality standard of the trial and clinical adherence is a determining factor on the success of a study. However, it has historically been difficult to systematically follow and understand patient adherence to medical ordinations, predominately due to lack of proper tools. One new type of tools is a digital pillbox that can be used to supply pills to participants in clinical trials. This paper examines implementing two supervised machine learning models to detect if an object (a pill) is found in an encapsulated compartment (pillbox) based on electromagnetic radiation data from a proximity sensor. Support Vector Machine (SVM) and Random Forest (RF) were evaluated on a data set of N=1,485 observations, consisting of five classes: four different pills and ‘no pill’. RF performs best with accuracy of 98.0% and weighted average precision of 98.0%. SVM had 97.3% accuracy and 97.6% weighted average precision. Best performance was achieved at N=1,000 for RF and 1,100 for SVM. The conclusion was that a high accuracy and precision can be achieved using either RF or SVM. The classification model strengthens the value proposition of a digital pillbox and can improve clinical trials to achieve better data quality. However, for the model to contribute actual economical value, digital pillboxes must be a common practice in clinical trials.
Kliniska studier är experiment eller observationer av en patients reaktion på olika typer av medicinsk vård för behandling sjukdomar. Sådana studier är tungt reglerade och behöver uppnå en viss kvalitésstandard och klinisk följsamhet är en avgörande faktor för en studies framgång. Trots det har det historiskt varit svårt att systematiskt mäta och förstå en patients följsamhet av en medicinsk ordination, primärt på grund av brist av användbara verktyg. En ny typ av verktyg är en digital pillerbox som försörjer piller till deltagare i kliniska studier. Denna studie undersöker implementation av två bevakade maskininlärningsmodeller för detektion om ett objekt (ett piller) befinner sig i ett slutet fack baserad på elektromagnetisk strålning från en närhetssensor. Support Vector Machine (SVM) och Random Forest (RF) utvärderades på ett dataset av N=1 485 observationer utgjort av fem klasser: fyra piller och ’inget piller’. RF presterar bäst med 98,0% i träffsäkerhet och 98,0% i viktad medelprecision. SVM fick 97,3% träffsäkerhet och 97,6% viktad medelprecision. Bäst prestation uppnåddes vid N=1 000 för RF och N=1 100 för SVM. Slutsatsen var att en hög träffsäkerhet och precision kan uppnås genom antingen RF eller SVM. Klassificeringsmodellen förstärker en digital pillerbox värdeerbjudande och kan hjälpa kliniska studier att uppnå högre datakvalité. Däremot, för klassificeringsmodellen ska bidra med faktiskt ekonomiskt värde, behöver digitala pillerboxar vara en vedertagen praxis.
