Full textAbstract:
The Android operating system, originally intended for smartphone devices, is now finding its way into cars and other vehicles. While the Android system already implements support for system updates, it is not suitable for use in the automotive domain. It is not compatible with modern automotive standards for diagnostic communication such as ISO 14229: Unified Diagnostic Services (UDS). This means that new tools, procedures and software would be needed to allow an Android device to be updated by a service technician in a repair shop or on the field. A better approach would be to add support for automotive diagnostic communication in Android. This way, the tools and supporting infrastructure that already exist can still be used. We have developed a solution for diagnostic communication on Android that is both modular and compatible with existing automotive standards. By using the standard ISO 13400: Diagnostic communication over Internet Protocol (DoIP), this solution enables both updating the system software on the Android device itself, as well as diagnostic communication with the ECUs on the vehicle’s internal CAN network. Thus, an existing diagnostic port based on a slower communication protocol such as CAN or J1587 could theoretically be replaced completely by the Android device’s Ethernet port. Finally, we have evaluated the performance of our implementation under various settings and conditions. These include varying the maximum size of a diagnostic message, different network settings, downloading software over a Wi-Fi link, and downloading data to multiple devices simultaneously.Operativsystemet Android, ursprungligen avsett för smartphone-enheter, återfinns numera även i bilar och andra typer av fordon. Även om Android-systemet redan implementerar stöd för system-uppdateringar, är det inte lämpligt att använda i fordonsindustrin. Den är inte kompatibel med moderna fordons-standarder för diagnoskommunikation som t.ex. ISO:14229: Enhetliga diagnostiktjänster (UDS). Detta innebär att det skulle krävas nya verktyg, procedurer och mjukvara för att möjliggöra att en Android-enhet uppdaterades av en service-tekniker i verkstad eller i fält. Ett bättre tillvägagångssätt skulle vara att lägga till support för diagnoskommunikation i Android. På detta sätt skulle redan existerande verktyg och stödjande infrastruktur kunna fortsätta användas. Vi har utvecklat en lösning för diagnoskommunikation i Android som är både modulär och kompatibel med existerande fordonsstandarder. Genom att använda ISO 13400: Diagnostikkommunikation över Internet-protokoll (DoIP) möjliggör denna lösning både uppdatering av systemmjukvaran i själva Android-enheten, samt diagnoskommunikation med övriga styrenheter på fordonets interna CAN-nätverk. Därmed skulle en befintlig diagnosport baserad på ett långsammare kommunikationsprotokoll såsom CAN eller J1587 teoretiskt kunna ersättas helt och hållet med Android-enhetens Ethernet-port. Slutligen har vi testat vår implementations prestanda under varierande inställningar och förhållanden. Dessa inkluderar bland annat att variera den maximala storleken av ett diagnos-meddelande, olika nätverks-inställningar, att uppdatera mjukvaran över en Wi-Fi-länk, samt att uppdatera mjukvaran på flera enheter samtidigt.

Full textAbstract:
A large-scale model of a tiltrotor wing and flap was built and tested to determine how the size and spacing of fluidic actuators for active flow control should be scaled up from laboratory size models to aircraft size. Flow control was provided by sweeping jet actuators mounted in the flap follower. Chordwise pressure data was collected through pressure taps located along the model centerline. The maximum flap deflection to which the flow could be attached with actuation was compared to previous experiments on a 10% 3D model. An ideal actuator spacing was found and the momentum coefficient was comparable between the various sized models. These results were used in the design of an industrial wind tunnel-scale model of a wing built for cruise and tiltrotor-like download testing. These tests have shown that actuators located in the flap follower are effective in both the hover and cruise phases of flight.

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorPensando a fotografia enquanto fenômeno comunicativo, numa perspectiva cartográfica associada à Teoria do Ator-Rede de Bruno Latour (2012), passamos a traçar os vínculos sociais, visuais e sensíveis que hoje põem em evidência o fazer lomográfico. Aqui, sob os relatos dos modos de fabricação e circulação da lomografia, pudemos adentrar estas redes de mediações sociotécnicas que desenham sua prática, bem como perceber o modo como construímos, no presente, a história das imagens nesse contexto. Já sob a diversidade de elementos que hoje reordenam nossas formas de ver, junto à noção de anacronismo (AGAMBEN, 2009; BENJAMIN; 1994; DIDI-HUBERMAN, 2010; RANCIÈRE, 2012), este gesto cartográfico nos levou tanto a buscar aspecto relacional e comunicativo da imagem lomo, quando a compreender a construção deste sentido visual frente à montagem de tempos heterogêneos. Processo onde as formas de apresentação e os atuais valores de uso lomo revelam, na imagem, seu caráter movente onde lugares do visível que se deslocam de seus contextos anteriores, renegociando socialmente suas condições de possibilidade no contemporâneo, podem ser redimensionados
Considering photography as a communicative phenomenon, based on a cartographic perspective associated to Actor-Network Theory by Bruno Latour (2012), this research enable us to outline the social, visual and sensitive bonds that highlight the modes of existence of lomographic experience. Here, reporting the modes of production and circulation of lomography, we were able to enter these networks of sociotechnical mediations that draw its practice, as well as we can perceive the way we build in the present the history of images in this context. Among the diversity of elements that reorder our ways of seeing, with the notion of anachronism (AGAMBEN, 2009; BENJAMIN; 1994; DIDI-HUBERMAN, 2010; RANCIÈRE, 2012) this cartographic gesture took us either to look at the relational and communicative aspect of the lomo image and to understand the construction of its visuality regarding the assembly of heterogeneous times by which it is made. This is a process where forms of presentation and current values of lomos use reveal within the image its moving characteristics. Where the visible is dislocated from its prior contexts, socially renegotiating the conditions of its possibilities in the present and where in so doing, it can be redimesioned

Full textAbstract:
For traditional web servers, available bandwidth decreases as the number of clients increases. This can cause servers to serve files slowly or to become completely overwhelmed when load grows too high. BitTorrent is a peer-to-peer solution to this problem, but it requires manual configuration for each file to be delivered this way. We develop a new system that integrates peer-to-peer file delivery with traditional client-server downloads. Clients initially attempt to download a file from a web server; if this is too slow, they transition to peer-to-peer delivery. Experiments with a prototype system show that it serves up to 30x faster than traditional web servers.

Internet has dominated the modern communication and information exchange and it is growing enormously day by day. Initially it is designed to off?er various applications like World Wide Web (WWW), Electronic Mail (E-Mail) and File Transfer (FTP). WWW has become very popular and today, Web traffic constitutes 70-80% in global Internet traffic. Web traffic generates by the end users, when they request for a web page. The web page transfers between various Web servers via different service networks to the end users. Web traffic has become very significant in the present world and the service providers have to offer best service to the customers. Quality of Service (QoS) is a measure of describing the performance of the service. Quality of Experience (QoE) explains the user perceived performance and it is subjective in nature. QoE influences the user satisfaction level, so QoS has to ensure to promote better QoE. User perceived QoE depends on page download time and it is an important parameter in evaluating the performance of web service. In this work we try to correlate the web page download times at both application-level and network-level. In particular, when there is a considerable delay in the network, we tried to correlate the application perceived download time with network-level download time. We explained the difference between application and network download times and how it varies with the applied delay. This work also shows how the download times at both levels are related to each other and their coefficient of correlation.Internet har dominerat modern kommunikation och informationsutbyte och den växer enormt varje dag.

I detta arbete försöker vi att korrelera webben gånger sidan ladda ner på både program-nivå och på nätverksnivå. I synnerhet när det finns en betydande fördröjning i nätet, försökte vi att korrelera ansökan upplevda tid för nedladdning med nät-nivå nedladdning tid. Vi förklarade skillnaden mellan applikationer och nätverk gånger hämta och hur den varierar med den tillämpade dröjsmål. Detta arbete visar också hur hämtningstider på båda nivåerna är relaterade till varandra och deras korrelationskoefficient.

A natureza de alguns dos produtos disponibilizados por estas máquinas, associado à criação de legislação em Portugal e na restante União Europeia, com o objectivo de assegurar o correcto manu-seamento e acondicionamento de produtos frescos, congelados e ultracongelados, obriga a que os operadores económicos tenham a necessidade proceder ao registo da temperatura do ar a que os produtos estão sujeitos enquanto estão armazenados dentro das máquinas. Para-lelamente, existe ainda a necessidade de as empresas procederem à descarga periódica da auditoria financeira dos moedeiros instalados nas máquinas. Actualmente no mercado existe um vasto conjunto de soluções que permitem a recolha dos dados de auditoria ambiental e financeira remotamente. No entanto o elevado custo dessas soluções torna diminuta a sua utilização em Portugal. Pretende-se com esta dissertação criar uma solução que visa proporcionar aos operadores económicos da indústria das máquinas de vending uma solução simples e eficaz para reco-lha de dados de auditoria, e que tire partido da deslocação regular dos repositores às máquinas de vending.

Full textAbstract:
In a highly mobile and networked society the need to download large amounts of data on a mobile network is inevitable. This thesis analyzes the predictability of download speeds in mobile networks to be able to schedule downloads while in areas with high download speeds. This decreases the download time and thus the energy wasted downloading. The data analyzed is from Bredbandskollen. We find that in areas of 200 x 200 meters the download speed is easiest to predict due to a low covariance. We also find that areas with high average download speed are more likely to have neighboring areas with similar download speed than areas with low average download speed, making it easier to predict the download speed when moving between such locations. Finally, we show paths in urban areas where a user can move long distances and experience similar download speeds.

Full textAbstract:
Abstract In visible light communication (VLC), light emitting diodes (LEDs) are used as transmitters; the air is the transmission medium and the photodiodes are used for receivers. This is often referred to as light fidelity (Li-Fi). In this thesis, we provide the methodology to evaluate the performance of VLC hotspot networks in the context of data downloading on the move scenarios by using throughput-distance relationship models. In this context, first we study the different properties of optical transceiver elements, noise sources, characterization and modelling of artificial light interference, different link topologies and then we introduce the throughput-distance relationship model. Secondly, the analytically based throughput-distance relationship has been developed for evaluating the performance of VLC hotspot networks in indoor environment in both day and night conditions. Simulation results reveal that background noise has a significant impact on the performance of VLC hotspots. As expected, in both indoor and outdoor environments the VLC hotspot performs better at night than during day. The performance of VLC hotspot networks is also quantified in terms of received file size at different bit error rate requirements and velocities of the mobile user. Thirdly, we study the performance of hybrid (Radio-Optical) WLAN-VLC hotspot and compare its performance with stand-alone VLC-only or WLAN-only hotspot cases. In this case, we also consider the data download on the move scenarios in an indoor environment for a single-user as well as for multi-user cases. In this hybrid WLAN-VLC hotspot, both the WLAN and the VLC are characterized by their throughput and communication range. Simulations have been performed to evaluate the performance of such network for data downloading on the move scenario by taking into account performance metrics such as filesize, average connectivity and system throughput. Simulation results reveal that the considered hybrid WLAN-VLC performs always better than stand-alone VLC-only or WLAN-only hotspot both for a single and multi-user cases. Finally, this thesis analyses the feasibility and potential benefits of using hybrid radio-optical wireless systems. In this respect, cooperative communication using optical relays are also introduced in order to increase the coverage and energy efficiency of the battery operated device. Potential benefits are identified as service connectivity and energy efficiency of battery operated device in an indoor environment. Simulation results reveal that user connectivity and energy efficiency depend on user density, coverage range ratio between single-hop and multi-hop, relay probabilities and mobility of the userTiivistelmä Näkyvään valoon pohjautuvassa tiedonsiirrossa (VLC) valodiodeja (LED) käytetään lähettiminä, ilma on siirtokanava ja valoilmaisimia käytetään vastaanottimina. Tätä kutsutaan usein nimellä light fidelity (Li-Fi). Tässä työssä tarjoamme menetelmiä VLC ”hotspot” verkkojen suorituskyvyn arviointiin tiedonsiirtonopeus-etäisyysmalleilla skenaarioissa, jossa tietoa ladataan liikkeessä. Tässä kontekstissa tutkimme ensin optisen lähettimen komponenttien eri ominaisuuksia, kohinan lähteitä, keinovalon häiriömalleja ja tiedonsiirtolinkkien topologioita, jonka jälkeen esittelemme tiedonsiirtonopeuden ja etäisyyden välisen mallin. Toiseksi kehitetyn analyyttisen tiedonsiirto-etäisyys mallia käytetään arvioitaessa VLC hotspot verkkojen suorituskykyä sisäympäristössä sekä päivä että yö olosuhteissa. Simulointien tulokset osoittavat, että taustakohinalla on suuri vaikutus VLC verkkojen suorituskykyyn. Kuten odotettua, sisä- ja ulkotiloissa VLC hotspot toimii paremmin yöllä kuin päivällä. VLC hotspot verkkojen suorituskyky arvioidaan myös vastaanotetun tiedoston koon, eri bittivirhesuhteen vaatimuksilla ja liikkuvan käyttäjän nopeuden suhteen. Kolmanneksi tutkimme hybridi WLAN-VLC hotspot verkon suorituskykyä ja vertaamme sen suorituskykyä pelkän VLC- tai WLAN hotspot tapauksessa. Käsittelemme myös skenaarioita jossa tiedoston lataus tapahtuu liikkeessä sisätilassa yhden käyttäjän sekä monen käyttäjän tapauksissa. Tässä hybridi WLAN-VLC hotspot, sekä erilliset WLAN- ja VLC verkot ovat määritelty niiden tiedonsiirtonopeuden ja kantaman perusteella. Näiden verkkojen suorituskykyä arvioitaessa on tehty joukko tietokonesimulointeja verkossa tapahtuvasta tietojen lataamisesta liikkeessä ottamalla huomioon suorituskyvyn mittarit kuten tiedoston koko, keskimääräinen yhteyden kesto ja saavutettu läpäisy. Simuloinnin tulokset paljastavat, että hybridi WLAN-VLC toimii aina paremmin kuin pelkkä VLC tai WLAN hotspot sekä yhden että monen käyttäjän tapauksessa. Lopuksi työssä analysoidaan ehdotetun järjestelmän toteutettavuus ja mahdolliset edut käytettäessä hybridejä radio-optisia langattomia järjestelmiä. Tältä osin esitellään myös kooperatiiviseen viestintään perustuvat optiset releet parantamaan verkon kattavuutta ja energiatehokkuutta akkukäyttöisissä laitteissa. Mahdolliset hyödyt tunnistetaan palvelun konnektiivisuudessa ja energiatehokkuudessa akkukäyttöisissä laitteissa sisätiloissa. Simulointien tulokset osoittavat, että käyttäjien konnektiivisuus ja energiatehokkuus riippuvat käyttäjätiheydestä, kantaman ja etäisyyden välisestä suhteesta yhden hypyn ja monen hypyn välillä, releointi todennäköisyydestä ja käyttäjien mobiliteetista

A disseminação do formato mp3 como padrão para arquivos de música, aliada ao crescimento da Internet, fez surgir uma poderosa rede de distribuição de música online. A extrema disponibilidade, diversidade de escolha e facilidade de acesso para quem possui banda larga em seus computadores fez crescer o download de músicas pela Internet, revolucionando o mundo fonográfico. O objetivo geral deste estudo é identificar quais fatores, na perspectiva do consumidor, têm maior influência no download gratuito de música pela Internet através de uma pesquisa exploratória de duas fases. Na primeira fase, qualitativa, foram realizadas entrevistas não estruturadas com usuários e consumidores de redes peer-to-peer de download de música pela Internet e entrevista semi-estruturada com um ex-executivo da indústria fonográfica. Na fase seguinte, quantitativa, foram aplicados questionários estruturados a pessoas que efetuam download de música pela Internet. Adotou-se a regressão linear múltipla como modelo para interpretar os dados colhidos junto à amostra e testar as hipóteses relacionadas as variáveis: acessibilidade ao produto, percepção de injustiça no preço e faixa etária. Os resultados sugerem a não rejeição das três hipóteses estudadas.

The aim of this study is to identify which factors, from the perspective of consumers, have more influence on the free download of music via the Internet through an exploratory research in two phases. In the first phase, qualitative, unstructured interviews were conducted with consumers and users of peer-to-peer downloading of music over the Internet and semistructured interview with a former executive of the music industry. In the following phase, quantitative, structured questionnaires were applied to people who download music from the Internet. It was adopted a multiple linear regression model to interpret the data collected from the sample and to test the hypotheses: product accessibility, perceptions of injustice in the price and age. The results suggest not rejecting the three studied hypotheses.

Mestrado em Gestão de Sistemas de InformaçãoO objetivo deste projeto pretende contribuir para o estudo de mercado das aplicações móveis em Portugal. Ao perceber e interpretar o feedback dos utilizadores portugueses os programadores, designers, comerciais e todas pessoas envolvidas nos lançamentos de aplicações poderão investigar e investir mais em aspetos, configurações e características que os utilizadores encontrem ser mais importantes e relevantes levando, então, quer ao sucesso da equipa, quer à satisfação dos utilizadores. Para tal, foi realizado um estudo através da formulação de um questionário, onde foram definidas variáveis com base nas preferências gerais de análise dos utilizadores e ainda com base nas normas internacionais criadas pela organização ISO, mais especificamente as normas ISO/IEC 9126-1:2000 e a ISO/IEC 25012. Posteriormente foi feita uma análise estatística com recurso a dois softwares Microsoft Office Excel e IBM SPSS Statistcs 25, que permitiram organizar a informação, assim como obter os resultados dos testes e análises estatísticas. Concluiu-se que, para os utilizadores portugueses, os comentários detalhados são mais impactantes que os comentários emocionais, que a avaliação geral de uma aplicação tem mais valor que os comentários e ainda que a norma ISO/IEC 9126-1:2000 é mais importante para a avaliação de uma aplicação.
The objective of this project will contribute to the market study of mobile applications in Portugal. By understanding and interpreting feedback from Portuguese users the developers, designers, commercials and everyone involved in releasing applications will be able to investigate and invest more in aspects, configurations and features that users find to be most important and relevant, thus leading to both team's success and user satisfaction. To this end, a study was carried out through the formulation of a survey, where variables were based on the general preferences of users analysis and also based on the international standards created by the ISO organization, specifically ISO / IEC 9126-1: 2000 and ISO / IEC 25012. Subsequently, a statistical analysis was performed using two softwares, the Microsoft Office Excel and the IBM SPSS Statistcs 25, which allowed the information to be organized, as well as find the results of the tests and statistical analyzes. It was possible to conclude that for the Portuguese users, detailed comments are more impactful than emotional comments, that the overall evaluation of an application has more value than comments, and that ISO / IEC 9126-1: 2000 is most important for the evaluation of an application.

Full textAbstract:
In the information age, the growth in availability of both technology and exploit kits have continuously contributed in a large volume of websites being compromised or set up with malicious intent. The issue of drive-by-download attacks formulate a high percentage (77%) of the known attacks against client systems. These attacks originate from malicious web-servers or compromised web-servers and attack client systems by pushing malware upon interaction. Within the detection and intelligence gathering area of research, high-interaction honeypot approaches have been a longstanding and well-established technology. These are however not without challenges: analysing the entirety of the world wide web using these approaches is unviable due to time and resource intensiveness. Furthermore, the volume of data that is generated as a result of a run-time analysis of the interaction between website and an analysis environment is huge, varied and not well understood. The volume of malicious servers in addition to the large datasets created as a result of run-time analysis are contributing factors in the difficulty of analysing and verifying actual malicious behaviour. The work in this thesis attempts to overcome the difficulties in the analysis process of log files to optimise malicious and anomaly behaviour detection. The main contribution of this work is focused on reducing the volume of data generated from run-time analysis to reduce the impact of noise within behavioural log file datasets. This thesis proposes an alternate approach that uses an expert lead approach to filtering benign behaviour from potentially malicious and unknown behaviour. Expert lead filtering is designed in a risk-averse method that takes into account known benign and expected behaviours before filtering the log file. Moreover, the approach relies upon behavioural investigation as well as potential for 5 system compromisation before filtering out behaviour within dynamic analysis log files. Consequently, this results in a significantly lower volume of data that can be analysed in greater detail. The proposed filtering approach has been implemented and tested in real-world context using a prudent experimental framework. An average of 96.96% reduction in log file size has been achieved which is transferable to behaviour analysis environments. The other contributions of this work include the understanding of observable operating system interactions. Within the study of behaviour analysis environments, it was concluded that run-time analysis environments are sensitive to application and operating system versions. Understanding key changes in operating systems behaviours within Windows is an unexplored area of research yet Windows is currently one of the most popular client operating system. As part of understanding system behaviours for the creation of behavioural filters, this study undertakes a number of experiments to identify the key behaviour differences between operating systems. The results show that there are significant changes in core processes and interactions which can be taken into account in the development of filters for updated systems. Finally, from the analysis of 110,000 potentially malicious websites, typical attacks are explored. These attacks actively exploited the honeypot and offer knowledge on a section of the active web-based attacks faced in the world wide web. Trends and attack vectors are identified and evaluated.

Full textAbstract:
The download duration of peer-to-peer overlay networks is highly dependent upon the client's selection of candidate node-servers and the algorithms used in that process. Recent findings suggest that as node-server network capacity increases the deviation from the average total download time can vary as much as 300 percent between selection algorithms. This work investigated the current selection algorithms based upon chunk size, parallel connections, permanent connection, and time based switching.
The time based switching algorithm is a variation of the chunk based algorithm. Time based switching enables a client to randomly select a new node-server regardless of connection speed at predetermined time slots. Simulations indicate a 41% percent decrease in download time when compared to chunk based switching.
The effects of inserting chokepoints in the time based switching algorithm were investigated. This work investigated improving a client's download performance by preemptively releasing a client from a poor performing node-server. To achieve this, the client will gather a peer-to-peer network overlay capacity from a global catalog. This information will be used to seed a client choke algorithm. Clients will then be able to continually update a local capacity average based upon past download sessions. This local average will be used to make a comparison between the current download session and the previously calculated average. A margin has been introduced to allow the client to vary from the average calculated capacity. The client will perform comparisons against chokepoints and make performance decisions to depart a node-server that does not meet minimum capacity standards.
Experimental results in this research demonstrated the effectiveness of applying a choking algorithm to improve upon client download duration as well as increasing the accuracy of download duration estimates. In the single downloader scenario, the choke based algorithm improved performance up to 44% in extreme congestion and a more modest 13% under normal conditions. The multiple client scenarios yielded on average a 1% decrease in client download duration along with a 44% increase download homogeneity. Furthermore, the results indicate that a client based choking algorithm can decrease overall peer-to-peer network congestion buy improving upon client selection of node-servers.

Este trabajo de tesis presenta los servicios de descarga de contenido en modo push como un
mecanismo eficiente para el envío de contenido de televisión pre-producido sobre redes de

de red a la entrega en vivo de contenido televisivo, tanto sobre redes de difusión como
sobre conexiones unidireccionales. Esta oferta de servicios responde únicamente a
requisitos comerciales: disponer de los contenidos televisivos en cualquier momento y
lugar. Sin embargo, desde un punto de vista estrictamente académico, el envío en vivo es
únicamente un requerimiento para el contenido en vivo, no para contenidos que ya han sido
producidos con anterioridad a su emisión. Más aún, la difusión es solo eficiente cuando el
contenido es suficientemente popular.
Los servicios bajo estudio en esta tesis utilizan capacidad residual en redes de difusión para
enviar contenido pre-producido para que se almacene en los equipos de usuario. La
propuesta se justifica únicamente por su eficiencia. Por un lado, genera valor de recursos de
red que no se aprovecharían de otra manera. Por otro lado, realiza la entrega de contenidos
pre-producidos y populares de la manera más eficiente: sobre servicios de descarga de
contenidos en difusión.
Los resultados incluyen modelos para la popularidad y la duración de contenidos, valiosos
para cualquier trabajo de investigación basados en la entrega de contenidos televisivos.
Además, la tesis evalúa la capacidad residual disponible en redes de difusión, por medio de
estudios empíricos. Después, estos resultados son utilizados en simulaciones que evalúan
las prestaciones de los servicios propuestos en escenarios diferentes y para aplicaciones

Nowadays, network operators dedicate a considerable amount of network resources to live streaming live, through both broadcast and unicast connections. This service offering responds solely to commercial requirements: Content must be available anytime and anywhere. However, from a strictly academic point of view, live streaming is only a requirement for live content and not for pre-produced content. Moreover, broadcasting is only efficient when the content is sufficiently popular. The services under study in this thesis use residual capacity in broadcast networks to push popular, pre-produced content to storage capacity in customer premises equipment. The proposal responds only to efficiency requirements. On one hand, it creates value from network resources otherwise unused. On the other hand, it delivers popular pre-produced content in the most efficient way: through broadcast download services. The results include models for the popularity and the duration of television content, valuable for any research work dealing with file-based delivery of television content. Later, the thesis evaluates the residual capacity available in broadcast networks through empirical studies. These results are used in simulations to evaluate the performance of background push content download services in different scenarios and for different applications. The evaluation proves that this kind of services can become a great asset for the delivery of television content

Peer-to-peer (P2P) applications have become a popular method for obtaining digital content. Recent research has shown that the amount of time spent downloading from a poor performing peer effects the total download duration. Current peer selection strategies attempt to limit the amount of time spent downloading from a poor performing peer, but they do not use both advanced knowledge and service capacity after the connection has been made to aid in peer selection. Advanced knowledge has traditionally been obtained from methods that add additional overhead to the P2P network, such as polling peers for service capacity information, using round trip time techniques to calculate the distance between peers, and by using tracker peers. This work investigated the creation of a new download strategy that replaced the random selection of peers with a method that selects server peers based on historic service capacity and ISP in order to further reduce the amount of time needed to complete a download session.

In the multiple clients simulation the new approach showed an average download duration improvement of 53.31% and an average cross ISP traffic reduction of 88.83% when ISPs were participating in cross ISP throttling. This new approach also significantly improved the consistency of the download duration between download sessions allowing for the more accurate prediction of download times.

Esta pesquisa analisa a permanência da cultura do vinil através das festas na cidade de Recife, que têm os DJs e os seus LPs como protagonistas. Buscamos conhecer esses profissionais, bem como os principais motivos que os levam a ainda tocar e consumir esse artefato cultural analógico, em plena era digital. Mesmo em face das facilidades que a música digitalizada oferece, com equipamentos mais leves e mais práticos, assim como uma oferta gratuita e quase irrestrita de fonogramas, esses DJs ainda preferem usar seus discos e dão muitas outras explicações além da qualidade sonora e da técnica de djing. Interessa-nos, também, como a circulação dos LPs através de rotas comerciais e de afeto, ao se encontrarem com os DJs em suas festas, podem formar uma interface ser humano – coisa e se constituir em processos de circularidade e cena. A partir do uso desses conceitos a hipótese é que espaços antes vazios podem ser transformados em lugares de significação, que abarcam sensibilidades e sociabilidade, assim como disputas e tensões. A tríade LP-DJs-Festas tem o poder de transformar ou influir na vida cultural de uma cidade, trazendo novos significados e experiências na maneira de vivenciar e olhar a cidade, e é o ponto nevrálgico dessa pesquisa. Procurou-se dar um entendimento a esse universo, articulando noções relacionadas a materialidade da mídia e práticas de consumo e coleção.

Full textAbstract:
Peer-to-peer networks are a common methodology used for content delivery and data sharing on the Internet. The duration of any particular download session is highly dependent on the capacity of the node servers selected as source peers. Recent investigations have shown that specific total download times may deviate significantly from average total download times. This work investigates a novel approach to selecting download server peers that is intended to reduce average total download times and minimize variance of those times from the overall average of download session durations.
Typical algorithms used in today's Peer-to-Peer (P2P) systems have improved from simply connecting to a single source peer for the entire download session to an approach where the download content is divided into chunks and a randomly selected source peer is chosen as the source for each chunk. This limits the possibility of an extremely long download session due to the selection of a low capacity download source peer. Prior work has demonstrated that it is better to divide the download session into time slices and download as much as possible from a randomly selected source peer within each time interval rather than staying connected to a poorly performing source peer for the entire time it takes to download a chunk of the source content. This approach minimizes the time spent with a poorly performing source peer and allows the client to move on to a potentially better performing source after a specific, limited interval. Other work has shown that by keeping a history of node performance, it is possible to recognize a poorly performing partner early in a time slice and depart to a new, and hopefully better performing partner, prior to the completion of a time slice (referred to as "choking" a poorly performing peer). These approaches have been shown to reduce average download times and minimize the variance in duration between download sessions.
Prior work has also shown that there is value in the use of parallel download streams. As long as the number of streams is kept small (i.e. 4 to 6), minimizing the overhead of maintaining numerous streams and saturation of the available incoming network bandwidth, average download time can be further reduced. The algorithm described in this investigation uses time-based source peer switching and maintains a small number of parallel download streams. At the end of each time interval, it does not randomly replace all source peers but keeps those source peers that are performing relatively better and replaces those performing relatively poorly with randomly selected new source partners. In this way, as the download progresses, parallel downloading typically progresses from a set of better and better performing source partners, therefore reducing average download times and reducing overall variance between download times. This approach has been shown in simulations to reduce average download times by nearly 20% over parallel versions of basic time-based downloads and 8.7% over time-based downloads with the addition of "choking" poorly performing partners. As file sizes increase and/or the heterogeneity of source node service capacities increase, the benefits of this approach to source peer replacement also increases. These improvements are gained while maintaining or further limiting the variance in performance between download sessions. The reduction in average download times and the decrease in variance between download sessions provided by this approach will improve the user experience for users of P2P content distribution systems. This approach should also be applicable to other data distribution systems such as distributed file systems.

The arrival of Digital TV has brought the possibility to broadcasters create interactive programs. For this, applications should be sent to the TV station via the standard DSMCC carousel. This standard enables data to be sent cyclically, so that any time you turn on the TV, it can receive all data transmitted. However, the way each interactive application will be available on the carousel has an impact on the users waiting time. The carousel can be modified to prioritize some applications, and so give more satisfaction to most users and also increase the profits of the station. It is not been defined yet a model of how to handle the priority of applications. Current work suggests an innovative business model, seeking to satisfy users, the broadcaster and the contractor.With the priorities of the applications, a new problem arises, termed here as the Download Time Variability Problem (DTVP). It defines the way that the carousel should be created to minimize the users waiting times. This is a difficult problem, which makes the use of exact techniques unapplicable for large instances. The paper proposes the use of GRASP and ILS metaheuristics to solve the problem.
A chegada da TV Digital trouxe consigo a possibilidade de criação de programas interativos por parte das emissoras. Para isso, aplicativos para TV devem ser enviados pela emissora através do padrão Carrossel DSM-CC. Esse padrão permite que os dados sejam enviados de forma cíclica, a fim de que a qualquer momento que o usuário ligue a TV, o mesmo possa receber todos os dados transmitidos. Porém, a forma com que cada aplicativo interativo vai estar disponível no carrossel tem um impacto no tempo de espera do usuário. O carrossel pode ser modificado de forma a priorizar algumas aplicações, e assim dar maior satisfação a maioria dos usuários e também aumentar o lucro da emissora. Ainda não existe um modelo definido de como tratar a prioridade das aplicações. O trabalho corrente sugere um modelo de negócio inovador, buscando satisfazer os usuários, a emissora e a empresa contratante. Com as prioridades das aplicações, surge um novo problema, denominado neste trabalho como o Problema da Variabilidade do Tempo de Download (PVTD). Ele trata da forma com que o carrossel deve ser gerado para minimizar o atraso no download das aplicações. Isso é um problema difícil, o que inviabiliza a utilização de técnicas exatas para grandes instâncias. O trabalho propõe a utilização das metaheurísticas GRASP e ILS para solucionar o problema.

This master thesis was carried out at Enea during the fall of 2007 with the purpose of investigating the implementation of software download through an external and secure communication link to every node in a DySCAS system. Furthermore it aimed at investigating how policies, which are a part of making the system behave autonomously, should be managed in the DySCAS project when it came to storing these in a repository. Finally, the AUTOSAR standardization, another automotive project, was studied for an investigation to be made about which requirements that should be set on the architecture of DySCAS, for it to co-exist with the AUTOSAR standardization. After an initial literature study, addressing the issues presented above, a design of the software system was carried out followed by an implementation and testing of this software. A general design of a system supporting software load, allowing both the replacement of one middleware component as well as the update of an entire node running in the DySCAS middleware, has been presented. In the subsequent implementation the possibility of using the CAN network to upgrade the software running on one or more DySCAS nodes with the help of an externally connected "upgrading node" has been explored and successfully implemented in the demonstrator platform. Furthermore, a Repository Service , using Enea's Polyhedra real-time database as the underlying repository, has been designed and implemented in the DySCAS demonstrator platform at Enea. The implemented software component supports the storage of policies and context information and thus aids the system in the objective of behaving autonomously. The Repository Service also provides the DySCAS system with a general storage facility, allowing other parts of the middleware or applications running on top of the middleware to store data. Finally, a design of how DySCAS and AUTOSAR should be elaborated to t together in one bigger system has been presented.

Full textAbstract:
The time it takes to download a file in a peer-to-peer (P2P) overlay network is dependent on several factors. These factors include the quality of the network between peers (e.g. packet loss, latency, and link failures), distance, peer selection technique, and packet loss due to Internet Service Providers (ISPs) engaging in traffic shaping. Recent research shows that P2P download time is adversely impacted by the presence of distant peers, particularly when traffic goes across an ISP that could be engaging in P2P traffic throttling activities. It has also been observed that additional delays are introduced when distant candidate nodes for exchanging data are included during the formation of a P2P network overlay. Researchers have shifted their attention to the mechanism for peer selection. They started questioning the random technique because it ignores the location of nodes in the topology of the underlying physical network. Therefore, selecting nodes for interaction in a distributed system based on their position in the network continues to be an active area of research. The goal of this work was to reduce the cumulative file download time and variance for the majority of participating peers in a P2P network by using a peer selection mechanism that favors nearby nodes. In this proposed proximity strategy, the Internet address space is separated by IP blocks that belong to different Autonomous Systems (AS). IP blocks are further broken up into subsets named zones. Each zone is given a landmark (a.k.a. beacon), for example routers or DNS servers, with a known geographical location. At the time peers joined the network, peers were grouped into zones based on their geographical distance to the selected beacons. Peers that end up in the same zone were put at the top of the list of available nodes for interactions during the formation of the overlay. Experiments were conducted to compare the proposed proximity based peer selection strategy to the random peer selection strategy. The results indicate that the proximity technique outperforms the random approach for peer selection in a network with low packet loss and latency and also in a more realistic network subject to packet loss, traffic shaping and long distances. However, this improved performance came at the cost of additional memory (230 megabytes) and to a lesser extent some additional CPU cycles to run the additional subroutines needed to group peers into zones. The framework and algorithms developed for this work made it possible to implement a fully functioning prototype that implements the proximity strategy. This prototype enabled high fidelity testing with a real client implementation in real networks including the Internet. This made it possible to test without having to rely exclusively on event-driven simulations to prove the hypothesis.

This study aims to discuss the mobile application users’ relationship between source of information and user's perceived value. And what will cuse to source of information and user's perceived value in different demographic variables. Most users think information as a fact, and have tend to reference the information. The information sources even will affect to an application users’ download evaluation decisions. However, the perceived value will further affect the users to use applications’ willing. Therefore, this study wants to discuss the influence of two variables, "source of information" and "perceived value" to the mobile application users’ download intention. This study was used investigated by the questionnaire and network questionnaire. Survey was in 2014 during April 20 to May 20 for one month. We got 610 valid questionnaires and 236 internet questionnaires. After reliability analysis, the Cronbach's α values are all above 0.8, shows the good reliability.

Mobile gaming now accounts for one of the top consumer behaviors on mobile device with estimates of 15billion market value by 2015. The goal of this study is to explore factors affecting mobile device users to download game apps based on the Unified Theory of Acceptance and Use of Technology(UTAUT) model while considering the moderating effects of game experience. Two of the constructs of UTAUT, effort expectancy(EE) and social influence(SI) are adopted and two additional constructs,game review and game popularity are developed..Particularly, this study investigates the role of personality factors in the UTAUT model. 475 participants completed an online survey and analysis of Moment Structures (AMOS) was used to test the measurement and structural model. The results show that the Big –Five personality traits are significant predictors of downloading game apps.EE, normative SI,game review and game popularity also have significantly postive effects on download intention while game-download intention is significantly postively related to download behavior. This study extends the UTAUT model by adding more constextual variables to understand mobile game users’ download intention and behavior. Theoretical and practical implications are also discussed.

Thanks to the advance of technology and the innovation of software and hardware, as well as the telecommunication liberation and market access, cell-phone market has entered its matured stage. The making cell-phones the consumer electronics taking up the largest market share in the technology industry. Smart phones and tablet computers are enjoying a worldwide attention of the consumers, boosting the demand for mobile application software. When more and more consumers are willing to use smart phones, consumers are also more willing to download mobile application software (App). In addition, cell phones are gradually become people’s daily functional products. Facing with growing App market, App providers should be more aware of the market demand and its trend, in order to create better opportunities and profits to the business. This study, based on the literature review, sorted out the factors affecting user’s evaluation on values of App from value perspective. Besides, an in-depth interview was also conducted to the App users to analyze the evaluation factors of App from the user’s point of view. After combining the results of literature review and of the in-depth interviews to the users, the evaluation factors affecting users in terms of downloading App were presented in the current study, including four primary standards, namely emotional value, social value, price value and quality value, and fourteen secondary standards. To understand the priority of these factors in decision making, the present study began with applying DEMATEL methods to determine the interrelationships among different factors. Then, an ANP framework was establish to analyze and prioritize each primary and secondary standards of how users think a certain App is worth downloading. The result showed that the primary factors affecting consumers in terms of downloading App are the quality valued, followed by the emotional value. The secondary factors are peer recognition, system effectiveness, security, social visibility and mobile efficiency are the top-five decision factors. The current study provided management suggestions according to its research results for APP designers and providers.

In Japan, where its market of music is only second to USA, the sales of the physical goods has reached its peak in 1998 by 607.5 billion Yen, followed by a steady down fall. On the other hand, although the scale of music download service haven’t reach one eighth of the sales of physical goods, it grows in an amazingly pace steadily. Under such circumstances, early Japanese record companies took a negative attitude since the music download service didn’t go well, and also in the fear of the sale of intangible goods may affect the sale of physical goods. When entering growth stage, the lack of numbers of goods, higher price and inconvenience comparing with the Western market, had limited the development of Japanese companies. There are several particularities of Japanese market of music download service. First of all, due to the early popularity of mobile Internet and improvement of mobile phone’s capability, downloading music by mobile phone had become the mainstream of the market. Secondly, most company offer only download by track before Napster entered the market, and finally, because of the complexity of copyright’s consignment, its digital right management is more rigid than its counter part in the west. In the mean time, when Western companies fought their way into the Japanese market, the key point of Japanese company is to raise their service quality, make good use of their own core competitively, and more over, to combine their software and hardware and make it their own advantage. This study is to explicate the overview of Japanese market of music download service, and to discuss the music download business in Japan by analyze current companies strategy by Strategies for Business System Design.

Drive-by download is a sort of network attack which uses different techniques to plant malicious codes in their computers. It makes the traditional intrusion detection systems and firewalls nonfunctional in the reason that those devices could not detect web-based threats. The Crawler-based approach has been proposed by many studies to discover drive-by download sites. However, the Crawler-based approach could not simulate the real user behavior of web browsing when drive-by download attack happens. Therefore, this study proposes a new approach to detect drive-by download by sniffing HTTP flow. This study uses reputation system to improve the efficiency of client honeypots, and adjusts client honeypots to process the raw data of HTTP flow. In the experiment conducted in real network environment, this study show the performance of a single client honeypot could reach average 560,000 HTTP success access log per day. Even in the peak traffic, this mechanism reduced the process time to 22 hours, and detected drive-by download sites that users were actually browsing. Reputation system in this study is applicable to varieties of domain names because it does not refer to online WHOIS database. It established classification model on machine learning in 12 features. The correct classification rate of the reputation system applied in this study is 90.9%. Compared with other Reputation System studies, this study not only extract features from DNS A-Type but also extract features from DNS NS-Type. The experiment results show the Error Rate of the new features from DNS NS-Type is only 19.03%.

We often see the device that broadcast the advertisement, for example the advertising machine in the lift or the shopping mall, and the most common way to change the file in the device is by the manpower at present. It can’t deal with the urgent state and wastes human resources. In this thesis, we propose a protocol and implement a server to control the remote devices. It can overcome the inconvenience of audio-visual file transfer, and the urgent state can be dealt with. The audio-visual materials are transmitted to the advertising device through the network, and the policies which the control center defined are conveyed to each machine through the network too, do not need to change the files artificially. The server we proposed offers the administrator to define the policies to make the advertising device broadcasting on schedule, and manage the relevant audio-visual materials with the function that modify immediately. Let the remote devices to download the policies and relevant audio-visual files, and broadcast relevant audio-visual files according to the administrator’s demand, avoid operating manually. We have to define the policies and the communication protocol between server and devices. The devices only need to update the relevant materials regularly through the network to achieve the goals of remote control and dealing with the emergency, for example halting broadcasting, or inserting text to marquee.

Dissertação de Mestrado em Engenharia Informática apresentada à Faculdade de Ciências e Tecnologia da Universidade de CoimbraAs operadoras de telecomunicações estão a perder um elevado número de receitas, já que os seus clientes começam a optar por soluções Over-The-Top (OTT), como o Skype, WhatsApp, Facebook ou Twitter, que oferecem melhores soluções a um custo reduzido. De forma a combater esta tendência, a Global System for Mobile Communications Association (GSMA) criou o Rich Comunication Suite (RCS) que consiste numa especificação de um conjunto de serviços - Voice Over IP (VoIP), Instant Message (IM), File Transfer (FT), entre outros - interoperáveis entre as várias redes das operadoras de telecomunicações. Várias soluções foram colocadas no mercado por diferentes operadoras, todas oferecendo um cliente de forma gratuita. Após garantirem uma sólida base de utilizadores, as operadoras vêm nestas soluções uma oportunidade de negócio. O modelo de negócio incide essencialmente na disponibilização de conteúdos de valor acrescentado aos seus utilizadores. A venda de Skins e de Stickers, por exemplo, está a ter um enorme sucesso nas aplicações OTT, tendo estas reportado receitas significativas resultantes da venda destes conteúdos. Neste relatório o autor apresenta as suas contribuições no desenvolvimento das funcionalidades de download e consumo de conteúdos de valor acrescentado nos clientes RCS da WIT Software e no cliente de messaging do grupo Vodafone intitulado de Message Plus.

Provisioning of video streaming service in Mobile P2P networks is challenged by many facts in transmission, such as high data loss rate, burst loss, unstable connectivity, link and peer host heterogeneity. This thesis addresses these transport issues by proposing two novel schemes, statistical download (SD) and blockless interleaving (BI), which cooperatively work with UEP-FEC channel coding. SD improves the successful rate of data download by exploiting multi-source download according to a RTT-based probability model. BI conducts different interleaving policies of data download from respective source peers according to the associated channel loss process. Simulation results show that even the system presents high volatility and heterogeneity, when the size grows into large, SD can improve on-time data rate with moderate traffic overheads. Meanwhile, BI can improve the error recovery performance of UEP-FEC by eliminating the packet loss correlation. It turns out that the video continuity is significantly improved.
