Richmond, Virginia has, through recent design proposals and projects, sought reconciliation with the countries in West Africa that were once the source for slave trade in which the city was such an active participant. These admirable works address the nations’ shared history, perhaps at the expense of understanding modern cultures. This thesis seeks to create this understanding through the development of an educational facility that would interact with Richmond’s current landscape. In pursuit of respectful relationship, I address the ways in which design can authentically teach about place. The study begins with the creation of a personal understanding of site through diagrammatic analysis. The research continues with case studies that relate to either the context, program or process of this project. The concepts this research generated led to a proposed design solution for the Southern Railway Freight building in Richmond’s Shockhoe Slip. Both design processes and the proposed solution are documented herein.

Detta projekt har haft som fokus att skapa ett system där användare med hjälp av SSH ska kunna logga in på en server och utföra konfigurationer på switchar och routrar med olika krav såsom att enbart en användare får vara inloggad i systemet åt gången. För att uppnå målen och kraven så användes ett par olika skript med språk såsom shell, bash, perl och expect. Resultatet visar en färdig produkt och att detta projekt var genomförbart. Lösningsförslaget finns presenterat i form av ett flödesschema och sedan vanlig text. Slutligen presenteras och diskuteras även andra alternativa lösningar.The projects main focus have been to create a system mainly for the users that study network technology on a more advanced level. In order for the students to start to configure the switches and routers they need to access a server with the SSH protocol which was one of the requirements. Another requirement was that only one user should be able to configure at same time (so two users should NOT be able to configure the switches and routers at the same time). The scripting languages that was used was bash, shell, perl and expect in order to achieve these goals and requirement. The result shows a finished product and that this project was feasable. The solution is presented as a flowchart as an overview and some regular text that explains the scripts in more depth. There are of course a ton of other ways to solve this problem and a few of them are presented and discussed in the later chapters.

I am a Christian. In my opinion, this is the most important way I can describe myself as a person. As a son, brother, friend, employee, and student my Faith undeniably affects every facet of my life. In an effort to make my last year as a student resonate on a personal level, I have combined my spiritual journey with my academic one. My intent was to characterize my Christian faith in order to introduce an architecture that embodies the duality of a personal connection to God and a community experience based on fellowship. My ten-week investigation of my beliefs, the Christian church, and architectural precedents has pointed me towards designing a remote worship destination in an effort to explore the intersection that occurs between the spiritual and earthly realms and between the individual and society. My hope is that this design will embody my concept of the Christian faith as a process, or journey, and the nature of that process causing a spiritual separation from society. My intention is to symbolically represent a journey, a point of rest and introspection, and to capture the nature of worship with an architecture and how that architecture responds to a site. My process thus far has been incredibly introspective and educational on so much more than an academic plane. My early research was fueled by cynicism and frustration with how I have seen the Christian faith and church represented in America today. However, diving deeper into the spirituality of Christian worship I have gained a beautiful perspective on our relationship with God and each other. I can only hope that my solution will reflect the spiritual growth I have experienced. If you want to make God laugh, tell Him your plans. Folk Proverb

Mestrado em Gestão de Sistemas de InformaçãoVive-se hoje uma época onde as organizações estão em constante mutação, as preocupações acrescidas com a qualidade e a performance tornaram o mundo empresarial um espaço agressivo e pouco tolerante ao erro. Contratar colaboradores culturalmente distantes ou geograficamente afastados, estimulando deste modo novas formas de trabalhar e cooperar passaram hoje a ser uma realidade e em alguns casos um fator diferenciador. Tentar compreender a existência de possíveis diferenças na gestão destas equipas, a viabilidade financeira da sua utilização o impacto da heterogeneidade cultural e geográfica no comportamento das mesmas são os grandes objetivos que o estudo pretende esclarecer. Para responder a estes temas, são abordados ao longo do estudo pontos essenciais para o correto funcionamento das Equipas Virtuais, sustentados numa investigação da literatura existente sobre o tema das Equipas Virtuais, com o intuito de aferir quais as caraterísticas principais já observadas por investigadores. Posteriormente é analisado um estudo de caso representativo da utilização de Equipas Virtuais, num contexto de um grande projeto de Sistemas de Informação. Foram recolhidas opiniões de alguns dos elementos participantes no projeto na forma de um questionário. Seguiu-se uma análise das respostas onde se obtiveram algumas conclusões. A necessidade de incentivar o uso de técnicas de inclusão como forma de eliminar as barreiras causadas pela distância física, a importância de aproximar os colaboradores fomentando uma maior cumplicidade e a relevância dos eventos presenciais na promoção da confiança, foram algumas das conclusões obtidas, cujo contributo espera-se, possa vir a ser útil a futuros investigadores.
Today is a time where organizations are constantly changing, increased concerns about quality and performance have made the business world an aggressive and not tolerant of error. Hiring culturally distant or geographically distant collaborators, stimulating new ways of working and cooperating, have now become a reality and in some cases a differentiating factor. Trying to understand the existence of possible differences in the management of these teams, the financial viability of their use and the impact of cultural and geographic heterogeneity on their behavior are the main objectives that the study intends to clarify.In order to respond to these themes, essential points for the correct functioning of the Virtual Teams, based on an investigation of the existing literature on the topic of Virtual Teams, are addressed throughout the study, in order to ascertain the main characteristics already observed by researchers. Subsequently a representative case study of the use of Virtual Teams is analyzed, in the context of a large Information Systems project. Opinions were collected from some of the project participants in the form of a questionnaire. This was followed by an analysis of the answers where some conclusions were obtained. The need to encourage the use of inclusion techniques as a way of eliminating the barriers caused by physical distance, the importance of bringing employees closer to each other and fostering more complicity and the relevance of face-to-face events in the promotion of trust were some of the conclusions obtained. It is hoped, may prove useful to future researchers.

During times of crisis, such as when the world is going through a pandemic. Many companies get affected and need to change their way of working. Our purpose is to study how the abrupt transition to remote work effects different aspects of work and to see whether, and in what ways, the involuntary nature of the current remote work situation changes how remote work is perceived by employees and managers. We choose to do a qualitative study, in order to get a deeper understanding from both employees’ perspective and managers perspective. The managers and employees participating in our interview are from banking, insurance, and staffing agencies. These interviews will be supplemented with secondary sources from news and statistical surveys. By comparing the results from our study with earlier research and recommendations from industry experts, we concluded that organizational members are handling the transition to remote work well despite the ongoing situation. Similar pros and cons of remote work that are present in previous research are also present in our interviews. However, there are some distinct differences as well. Our thesis is intended to help other organizations learn and gain knowledge about how different organizations are managing remote work in a crisis and the challenges that it brings.

The purpose of this thesis is to develop a remote control application for personal computers. This application will have two devices implied, the computer to be controlled and a small portable device that will be used as remote controller.
In this specific case, the portable device picked is the Nintendo DS, for reasons discussed later in this document that make this device interesting as a remote controller.
The application should allow the final user to create his own set of remote controllers for any computer application he wants to control, and also, to define the commands the application should perform. This makes the developed solution a full customizable universal remote controlling application.
The first step taken was to do a small research about what kind of devices and software are present actually for remote control applications, so the differences, advantages and disadvantages of using the Nintendo DS will be shown. Then the developed solution will be explained and tested, controlling some computer applications under different scenarios.

International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, NevadaA Remote Telemetry Station (RTS) was developed to support Boeing’s requirement to relocate its flight test telemetry range away from Seattle, Wa. As requirements to relocate the test range were investigated high level requirements were documented and various approaches were evaluated. The end result of the analysis and requirements definition was the procurement of the Remote Telemetry Station (RTS). The RTS is capable of supporting many sites, tracking and receiving up to 1024 Kbits/sec of telemetry data, providing fully redundant two-way radio communication in the UHF and VHF bands, linking all the data back to Seattle and appearing transparent to the users. The RTS was designed and developed by a Boeing/Veda Incorporated team. The end result of this joint design and development effort is a system that meets all Boeing requirements in a highly integrated, extremely efficient, and very flexible package providing for growth through the year 2000.

Today, many small aerodromes have a hard time surviving economically, and amongst the largest cost is air traffic control. Airlines are cutting costs where they can, and many times this affects the aerodromes as well, e.g. when airlines decide to park remotely instead of at the gate. The project called Remotely Operated Towers, initiated by SESAR and run by Saab and LFV, is aiming to address this problem. The project revolves around remotely providing ATS to aerodromes where it is deemed suitable. A big challenge in this project is how to assign aerodromes to remote tower modules in the remote control centre. There are many ways to do this, but there is only a few ways to do it to achieve the least amount of modules. This thesis aims to find an optimal solution to the challenge mentioned above. The thesis resulted in a model where the user can provide the input of choice, i.e. aerodromes with associated ATS operating hours and movements, for a specific period – and receive the assignment schedule for the modules, saying exactly which aerodrome are to be controlled by which module at what time.

Context. Introduction of efficient multimedia technologies combined with the spreading of high-speed internet connection all over the world has led to the continuous increase in demand of multimedia services, particularly video and audio. One of the major demands are flexible, interoperable and cost-effective lightweight remote collaboration systems in companies. Web Real Time Communication (WebRTC) is an emerging peer to peer technology that is promising to be the solution to many digital real-time communication challenges. With its fantastic one-to-one communication capabilities, WebRTC supports fast and smooth audio calls, video calls, conferencing, data (media file, document and screen) sharing, gaming and all sorts of messages exchange, all being done straight out of the browser. However, as shown by investigations and interviews supported by Ericsson AB and Semcon AB as party of the MERCO (Mediated Effective Remote Collaboration) international project, many corporate use cases of remote collaboration involve applications beyond the conventional one to one communication. Present videoconferencing systems (telepresence) limits the collaboration flexibility due to their lack of the ability to adapt to system resource usage, hence tend to be too heavy for less powerful devices (laptops, tablets, phones). Moreover, their installation and maintenance costs are too expensive for small companies. Therefore, new flexible, lightweight and less expensive solutions for remote collaboration need to be developed. Objectives. The main objective of this thesis is to identify technical solutions to address the challenges of resource usage flexibility in WebRTC multi-party remote collaboration systems. Despite concurrent developments of both commercial and free solutions that provide multi-party videoconferencing services using WebRTC, present solutions such as the conventional Multipoint Control Unit (MCU), Selective Forwarding Unit (SFU) and Fully Meshed architectures suffers from issues of excessive resource usage and cannot deliver the acceptable quality of experience in different use cases, particularly the mobile environment. The aim of this thesis is to investigate lightweight technical solutions that can be used to improve the system resource usage in WebRTC multiparty conferencing systems. Through understanding the architectural designs, benchmarking the performance of various technologies used in WebRTC and selecting the most suitable techniques a prototype is developed as a proof of concept. Methods. The first part of the thesis is dedicated to comprehensive study of fundamentals, background information and related works on WebRTC. This gives knowledge of technologies, techniques and performance evaluation metrics which help in making appropriate technical decisions during the experimental development of WebRTC solutions. The second part of the thesis is dedicated to experimental investigation in which two WebRTC signaling technologies (XSockets and NodeJs) are evaluated based on call setup time in WebRTC group call. Two lightweight technical solutions for improving resource usage flexibility (Switching video quality based on speech and using emotions and gestures instead of video) are evaluated based on system resources (CPU, memory, disk and network) and user experience. Results. Based on call setup time of WebRTC multi-party calls, the experimental results indicates that XSockets is a better signaling technology than NodeJs. The two proposed lightweight solutions have shown a remarkable improvement based on systems resource usage. A 15% reduction of CPU usage is observed when using speech controlled video quality switching and further 10% reduction is observed when video is replaced by emotions and gestures. Conclusions. Despite the minimal resource usage achieved by using emotions technique, this solution has usability issues as it cannot detect emotions in poor lighting environment. Consequently, the solution of switching video quality based on speech is chosen for further implementation. Though, this technique can be further improved through using machine learning techniques, the current implementation can significantly reduce the amount CPU, memory, disk and network usage to allow up to 6 participants to join a single conference call while maintain acceptable quality of experience.

Resumo: A presente pesquisa objetivou elaboração de uma proposta de ordenamento da ocupação territorial da Sub-bacia Hidrográfica do Baixo Rio Candeias, localizada no Estado de Rondônia, utilizando ferramentas de Sensoriamento Remoto e Sistemas de Informações Geográficas na avaliação do processo de mudanças de uso da terra para subsidiar o planejamento de bacias hidrográficas. Nesta pesquisa, utilizou-se imagens de satélite digitais e analógicas e Sistema Processamento de Informações Georreferenciadas - SPRING, disponibilizados pelo Instituto Nacional de pesquisas Espaciais - INPE, no qual foram armazenadas, processadas e analisadas todas as informações inerentes a pesquisa. Inicialmente foi realizado um Diagnóstico Zero da sub-bacia, que serviu de base de dados para estabelecer e identificar as deficiências técnicas que necessitam ser complementadas em função das necessidades das comunidades abrangidas. Através da análise da rede de drenagem foi possível analisar a morfoestrutura e morfotectonica da área, identificando as falhas e fraturas, bem como, anomalias do tipo alto/baixo estrutural. Foi realizada uma caracterização das unidades fisiográficas, definidas a partir da interpretação das imagens orbitais, com identificação das formas, reconhecimento e deduções dos fenômenos na elaboração da paisagem atual e subatual. A estas informações foram agregadas, informações de pedologia de fundamental importância para entender a dinâmica e evolução da paisagem e consequentemente, na elaboração do mapa de subzonas. Os limites das Subzonas coincidiram com os limites das unidades de solos incrementadas a unidades geológicas, e como resultado definiu-se dezenove subzonas, que agruparam todas as informações (morfoestrutura e morfotectonica, fisiografia, solos, vegetação e litologia) produzidas e pesquisadas...

Abstract: This research objective was to prepare a proposal of suitable land uses for the Lower Candeias River Watershed, geographically located within the State of Rondônia, Brazil, using Remote Sensing and Geographic Information Systems approaches to assess land use and land cover change processos and to provide information to support preparation of a sustainable watershed occupation plan. Satellite imagery and a Geographic Information System (SPRING) developed by the National Space Research Institute (INPE) were used to store, process, and analyze digital datasets. Initially, a "Zero Diagnostic" of the Lower Candeias River Watershed was prepared. This diagnostic was used as supporting information to identify technical weakness in the methodological approaches, which required complementary efforts given the local community and environmental characteristics. In addition, based on the river network analysis, it was possible to define the morphostructure and morphotectonic of the study area, which made possible to identify geologic faults and fractures, and low/high structural anomalies. Physiographic units were identified by analyzing satellite imagery, which included form identification, recognition and deduction of the phenomenon that were shaping current and previous landscape. The critical pedologic information were aggregated to support analysis of the dynamic and evolution of the landscape and, subsequently, to support preparation of the subzoning map of the Lower Candeias River Watershed. The subzones limits overlapped the soil unit limits and, by merging them with the geologic units, it resulted in 19 new subzones. Therefore, these new 19 subzones incorporated all information (morfoestrutura and morfotectonica, fisiografia, ground, vegetation and litologia) derived from this dissertation research. Therefore, the land use map... (Complete abstract click electronic access below)

Wireless Sensor Network (WSN), a collection of “sensor nodes” promises to change the scientist’s approach of gathering the environmental data in various fields. Sensor nodes can be used for non-stop sensing, event detection, location sensing and local control of actuators, this concept gives surety to many latest application areas like agriculture, military, home or factory automation, logistics and so on. Remote surveillance and measurement missions can be performed by using WSNs. The hot research topic now-a-days is to make such networks remotely controllable and adaptive to the environment and mission.
The work carried out in this thesis is the development of a surveillance application using TinyOS/nesC. The purpose of this application is to perform event-detection mission by using any one of the built-in sensor on Mica2 motes as well as a setup protocol is designed to make the WSN remotely controllable and adaptive to the mission. In this thesis, an experimental work is also performed using TinyDB to build up a surveillance system whose purpose is to detect and count the total number of person present at any time in a given room and to view the results at a remote place. Besides these two system applications, a comparative study between TinyDB and nesC is described which concludes that more hardware control can be achieved through nesC which is a more power efficient platform for long-term applications.

Unmanned Aerial Vehicles (UAVs) have a tremendous appeal. One can imagine a large number of applications such as search-and-rescue, traffic monitoring, aerial mapping, etc. Helicopters are particularly attractive due to their Vertical Take Off and Landing (VTOL) capabilities. The research on UAVs has shown rapid development in recent years, and offers a great number of challenges. This thesis is the result of a project which is a part of the Autonomous Remote Controlled Helicopter (ARCH) project at the Department of Computer and Information Science, Norwegian University of Science and Technology. The ARCH project has already gained public interest, when it was featured on a television program (Schrödingers katt, NRK. September 2004). The object of this thesis is divided into three main sections. Firstly, it is to create and describe a remote control system for controlling the UAV in semi-autonomous mode, that will also enable the UAV to autonomously follow objects (pursuit-mode). Secondly, it is to create and describe a virtual cockpit which is to be used with the remote control system. Finally, it is to create and describe an image stabilization system, which can stabilize the visual information sent from the UAV to the ground and the virtual cockpit. These three components have been combined and integrated into the client prototype called ARCH Groundstation. Together, these three components provides a platform for an operator to control the ARCH UAV in semi-autonomous mode.

Image analysis plays a crucial role in many computer vision applications in which images of the same scene with different geometrical orientations need to be compared for further processing. This thesis describes the design and implementation of a model-based vision system for the recognition of aerial images. The main objective is to register two remote sensing images taken at different times. First, some distinctive features are extracted and matched then, these matched features are used as marking points in defining a geometric mapping function. Once registered, the reference image can be used as an aid to automatic interpretation and as a framework for detecting changes between successive images. A two stage matching procedure is used for this task. In the first part, corners are extracted and matched in both images and an initial estimation of the mapping function is computed. This initial function is then used in the second part to estimate the parameters of a global mapping function for the entire image. The process ends when all the extracted features in one image are either mapped to features in the other image, or rejected if no match could be found.

The aim of this research was to develop and validate a conceptual design management model for international, collaborative remote site projects. In the last decade or so there has been an increasing number of remotely located and often environmentally sensitive sites becoming the focus for development work involving potential investors/entrepreneurs/stakeholders or government and non-government agencies. There were no previously documented empirical examples, nor theoretical models, for remote site design management. Projects on remote sites are frequently government funded, making the approval processes, and timelines for example, subject to political influence, which means that the projects are potentially more difficult to manage, at all levels of involvement. The conceptual model was developed in association with the development of a typology for remote sites, and an investigation of three previously completed eco-resort and Antarctic science projects located on environmentally sensitive world heritage sites. The model responded to and reflected the perceived need for a well-integrated management approach to remote site projects. The research aimed to also demonstrate the potential portability of the model, in terms of offering a basis for a relevant management framework for built environment projects, international scientific drilling projects and international humanitarian aid projects. Grounded theory and case-study methodology were adopted when developing the typology, the conceptual model and when validating the design management model, as it involved empirical enquiry that afforded investigation of the remote site design management phenomenon within a real-life contexts. Two main case studies were undertaken to test the model, one being an historical Antarctic Science Drilling Project and the other, a current UN Humanitarian Project in Sudan. The findings to date support the conceptual design management model as being relevant for not only non-profit and/or Humanitarian Aid projects in the Post-disaster Reconstruction context, but also for commercially based Antarctic Science projects. Subsequently, the model has also been applied to a Post-disaster Reconstruction project in Aceh managed by the Jesuit Refugee Services (JRS).

Vid tillfällen då det inte lämpar sig att stå vid en videokamera kan det lösas med ett fjärrstyrt kamerafäste. Exempel på tillfällen är på grund av platsbrist på en konsert, en högtidsceremoni där någon måste stå konstigt till för att få bra bild, ute i naturen där djur ska filmas utan att bli ivägskrämda eller vid personalbrist, en tight budget och måste styra flera kameror samtidigt. De system som finns tillgängliga på amatörmarknaden idag har antingen annan funktionalitet och passar sig inte för ovanstående problem eller har väldigt begränsad räckvidd och går inte att sammankoppla med en mobilapplikation. Detta projekt går ut på att ta fram en kostnadseffektiv och skräddarsydd lösning för ovanstående problem genom att utveckla ett fjärrstyrt kamerafäste i semiproffssegmentet där det via en handkontroll och vid senare skede med en mobilapplikation styr kamerans lutning och rotation även kallad tiltning och panorering. Skillnaderna mellan denna och befintliga lösningar är att med hjälp av Bluetooth-tekniken kan styra både med handkontroll och senare även med en mobilapplikation, anledningen till att det skall kunna styra med båda är att det inte alltid är tillåtet att använda sig av mobiltelefoner i alla miljöer där man vill filma och därför får ett bredare användningsområde för kamerafästet.At times when it is not suited to stand by a video camera can be resolved with a remote controlled camera mount. Examples of occasions is due to lack of space at a concert, a solemn ceremony in which someone must stand awkwardly to to get good image, out in nature where animals shall be filmed without being frightened away or when you have staff shortages, a tight budget and need to control multiple cameras simultaneously. The systems that are available in the amateur market today have different functionality and is not fitting for the above problem or have very limited range and cannot connect to a mobile application. This project aims to develop a cost-effective and customized solution for the above problem by developing a remote-controlled camera mount in semi-professional segment where you through a controller and at a later stage with a mobile application controls the camera angle and rotation also called tilt and pan. The differences between this and existing solutions are that by using Bluetooth technology can control both the controller and later on also with a mobile application, the reason why it must be able to control both is that it is not always allowed to use cell phones in all environments where you want to film and therefore have a wider range of applications for camera mounting.

A remote residential control system enables home users to remotely manage devices at their homes. These devices may include energy management, security surveillance, household appliances, consumer electronics, etc. This system involves technologies in home automation, home networking, and interfacing a home network with external networks. However, lacking a single standard poses a big challenge to the design of such a system. This thesis proposed three methods of turning an IP Set-Top Box into a remote residential control platform. Additionally, future trends are discussed. Various technologies in the fields mentioned above are also examined.Ett system för fjärrstyrning av intelligenta hem (remote residential control system) är ett system som möjliggör för hemanvändare att på distans övervaka och styra utrustning i hemmet. Denna utrustning kan vara energiövervakning, säkerhetsutrustning, hushållsapparater, konsumentelektronik, etc. Det saknas dock en gemensam standard, vilket gör det till en stor utmaning att konstruera ett sådant system.

Les champs de lumière ont attisé la curiosité durant ces dernières décennies. Capturés par une caméra plénoptique ou un ensemble de caméras, ils échantillonnent la fonction plénoptique qui informe sur la radiance de n'importe quel rayon lumineux traversant la scène observée. Les champs lumineux offrent de nombreuses applications en vision par ordinateur comme en infographie, de la reconstruction 3D à la segmentation, en passant par la synthèse de vue, l'inpainting ou encore le matting par exemple.Dans ce travail nous nous attelons au problème de reconstruction du champ de lumière dans le but de synthétiser une image, comme si elle avait été prise par une caméra plus proche du sujet de la scène que l'appareil de capture plénoptique. Notre approche consiste à formuler la reconstruction du champ lumineux comme un problème de rendu basé image (IBR). La plupart des algorithmes de rendu basé image s'appuient dans un premier temps sur une reconstruction 3D approximative de la scène, appelée proxy géométrique, afin d'établir des correspondances entre les points image des vues sources et ceux de la vue cible. Une nouvelle vue est générée par l'utilisation conjointe des images sources et du proxy géométrique, bien souvent par la projection des images sources sur le point de vue cible et leur fusion en intensité.Un simple mélange des couleurs des images sources ne garantit pas la cohérence de l'image synthétisée. Nous proposons donc une méthode de rendu direct multi-échelles basée sur les pyramides de laplaciens afin de fusionner les images sources à toutes les fréquences, prévenant ainsi l'apparition d'artefacts de rendu.Mais l'imperfection du proxy géométrique est aussi la cause d'artefacts de rendu, qui se traduisent par du bruit en haute fréquence dans l'image synthétisée. Nous introduisons une nouvelle méthode de rendu variationnelle avec des contraintes sur les gradients de l'image cible dans le but de mieux conditionner le système d'équation linéaire à résoudre et supprimer les artefacts de rendu dus au proxy.Certaines scènes posent de grandes difficultés de reconstruction du fait du caractère non-lambertien éventuel de certaines surfaces~; d'autre part même un bon proxy ne suffit pas, lorsque des réflexions, transparences et spécularités remettent en cause les règles de la parallaxe. Nous proposons méthode originale basée sur l'approximation locale de l'espace plénoptique à partir d'un échantillonnage épars afin de synthétiser n'importe quel point de vue sans avoir recours à la reconstruction explicite d'un proxy géométrique. Nous évaluons notre méthode à la fois qualitativement et quantitativement sur des scènes non-triviales contenant des matériaux non-lambertiens.Enfin nous ouvrons une discussion sur le problème du placement optimal de caméras contraintes pour le rendu basé image, et sur l'utilisation de nos algorithmes pour la vision d'objets dissimulés derrière des camouflages.Les différents algorithmes proposés sont illustrés par des résultats sur des jeux de données plénoptiques structurés (de type grilles de caméras) ou non-structurésLight fields have gathered much interest during the past few years. Captured from a plenoptic camera or a camera array, they sample the plenoptic function that provides rich information about the radiance of any ray passing through the observed scene. They offer a pletora of computer vision and graphics applications: 3D reconstruction, segmentation, novel view synthesis, inpainting or matting for instance.Reconstructing the light field consists in recovering the missing rays given the captured samples. In this work we cope with the problem of reconstructing the light field in order to synthesize an image, as if it was taken by a camera closer to the scene than the input plenoptic device or set of cameras. Our approach is to formulate the light field reconstruction challenge as an image-based rendering (IBR) problem. Most of IBR algorithms first estimate the geometry of the scene, known as a geometric proxy, to make correspondences between the input views and the target view. A new image is generated by the joint use of both the input images and the geometric proxy, often projecting the input images on the target point of view and blending them in intensity.A naive color blending of the input images do not guaranty the coherence of the synthesized image. Therefore we propose a direct multi-scale approach based on Laplacian rendering to blend the source images at all the frequencies, thus preventing rendering artifacts.However, the imperfection of the geometric proxy is also a main cause of rendering artifacts, that are displayed as a high-frequency noise in the synthesized image. We introduce a novel variational rendering method with gradient constraints on the target image for a better-conditioned linear system to solve, removing the high-frequency noise due to the geometric proxy.Some scene reconstructions are very challenging because of the presence of non-Lambertian materials; moreover, even a perfect geometric proxy is not sufficient when reflections, transparencies and specularities question the rules of parallax. We propose an original method based on the local approximation of the sparse light field in the plenoptic space to generate a new viewpoint without the need for any explicit geometric proxy reconstruction. We evaluate our method both quantitatively and qualitatively on non-trivial scenes that contain non-Lambertian surfaces.Lastly we discuss the question of the optimal placement of constrained cameras for IBR, and the use of our algorithms to recover objects that are hidden behind a camouflage.The proposed algorithms are illustrated by results on both structured (camera arrays) and unstructured plenoptic datasets

The aim of this thesis is to study and advance technology relating to remote rendering of Virtual Reality (VR). In remote rendering, rendered content is commonly streamed as video images in network packets from a server to a client. Experiments are conducted with varying networks and configurations throughout this work as well as with different technologies that enable or improve remote VR experiences. As an introduction to the field, the thesis begins with related studies on 360-video. Here, a statistic based on throughput alone is proposed for use in light-weight performance monitoring of encrypted HTTPS 360-video streams. The statistic gives an indication of the potential of stalls in the video stream which may be of use for network providers wanting to allocate bandwidth optimally. Moving on from 360-video into real-time remote rendering, a wireless VR adapter, TPCAST, is studied and a method for monitoring the inputand video-throughput of this device is proposed and implemented. With the monitoring tool, it is for example possible to identify video stalls that occur in TPCAST and thus determine a baseline of its robustness in terms of video delivery. Having determined the baseline, we move on to developing a prototype remote rendering system for VR. The prototype has so far been used to study the bitrate requirements of remote VR and to develop a novel method that can be used to reduce the image size from a codec-perspective by utilizing the Hidden Area Mesh (HAM) that is unique to VR. By reducing the image size, codecs can run faster and time will therefore be saved each frame, potentially reducing the latency of the system.

Interactive system developers spend most of their time and resources on user interface
evaluation in traditional usability laboratories. Since the network itself and the remote

Remote usability evaluation that takes interface evaluation of any application beyond the

Nesta pesquisa, utilizou-se imagens de satélite digitais e analógicas e Sistema Processamento de Informações Georreferenciadas – SPRING, disponibilizados pelo Instituto Nacional de pesquisas Espaciais – INPE, no qual foram armazenadas, processadas e analisadas todas as informações inerentes a pesquisa. Inicialmente foi realizado um Diagnóstico Zero da sub-bacia, que serviu de base de dados para estabelecer e identificar as deficiências técnicas que necessitam ser complementadas em função das necessidades das comunidades abrangidas. Através da análise da rede de drenagem foi possível analisar a morfoestrutura e morfotectonica da área, identificando as falhas e fraturas, bem como, anomalias do tipo alto/baixo estrutural. Foi realizada uma caracterização das unidades fisiográficas, definidas a partir da interpretação das imagens orbitais, com identificação das formas, reconhecimento e deduções dos fenômenos na elaboração da paisagem atual e subatual. A estas informações foram agregadas, informações de pedologia de fundamental importância para entender a dinâmica e evolução da paisagem e consequentemente, na elaboração do mapa de subzonas. Os limites das Subzonas coincidiram com os limites das unidades de solos incrementadas a unidades geológicas, e como resultado definiu-se dezenove subzonas, que agruparam todas as informações (morfoestrutura e morfotectonica, fisiografia, solos, vegetação e litologia) produzidas e pesquisadas...
This research objective was to prepare a proposal of suitable land uses for the Lower Candeias River Watershed, geographically located within the State of Rondônia, Brazil, using Remote Sensing and Geographic Information Systems approaches to assess land use and land cover change processos and to provide information to support preparation of a sustainable watershed occupation plan. Satellite imagery and a Geographic Information System (SPRING) developed by the National Space Research Institute (INPE) were used to store, process, and analyze digital datasets. Initially, a “Zero Diagnostic” of the Lower Candeias River Watershed was prepared. This diagnostic was used as supporting information to identify technical weakness in the methodological approaches, which required complementary efforts given the local community and environmental characteristics. In addition, based on the river network analysis, it was possible to define the morphostructure and morphotectonic of the study area, which made possible to identify geologic faults and fractures, and low/high structural anomalies. Physiographic units were identified by analyzing satellite imagery, which included form identification, recognition and deduction of the phenomenon that were shaping current and previous landscape. The critical pedologic information were aggregated to support analysis of the dynamic and evolution of the landscape and, subsequently, to support preparation of the subzoning map of the Lower Candeias River Watershed. The subzones limits overlapped the soil unit limits and, by merging them with the geologic units, it resulted in 19 new subzones. Therefore, these new 19 subzones incorporated all information (morfoestrutura and morfotectonica, fisiografia, ground, vegetation and litologia) derived from this dissertation research. Therefore, the land use map... (Complete abstract click electronic access below)

Resumo: O monitoramento de vulcões é necessário para a mitigação do perigo que apresentam à sociedade. Esse monitoramento pode ser feito em uma escala global através de satélites. Foi com essa finalidade que este doutorado visou desenvolver metodologias para o monitoramento das atividades termais dos vulcões observados do espaço. Chegou-se a isso através do uso de uma variedade de sensores infravermelhos orbitais. Foi utilizado o sensor Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), que oferece imagens de moderada a alta resolução espacial (30 - 90 m) no infravermelho das ondas curtas (SWIR) e infravermelho termal (TIR), a fim de caracterizar o tamanho e a intensidade das anomalias termais. As bandas do TIR do ASTER conseguiram detectar anomalias sutis, o que permitiu a observação de novos precursores termais antes das erupções. O Moderate Resolution Imaging Spectroradiometer (MODIS) oferece imagens de alta resolução temporal (i.e. cobertura global diária), por isto foi utilizado para investigar atividade termal através do tempo. A análise de wavelets foi utilizada para quantificar os períodos de oscilação de tal atividade. Hyperion é um espectroradiômetro imageador e foi utilizado para demonstrar uma nova metodologia para calcular fluxo radiante de alvos termalmente heterogêneos (i.e. vulcões). Essas metodologias utilizam as melhores resoluções de cada um dos sensors: espacial (ASTER), temporal (MODIS), espectral (Hyperion) pode ser automaticamente executadas em escala global. Essa tese visa, portanto apresentar uma fundação sólida onde futuros sistemas de monitoramento de vulcões podem ser baseados
Abstract: Volcanoes need to be monitored to mitigate the risk that they pose to society. This can be done on a global scale using satellite sensors. The goal of this doctorate was to develop methods for the monitoring of volcanic thermal activity from space. This was achieved through the use of a variety of orbital infrared sensors. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), which offers moderate to high spatial resolution imagery (30 - 90 m) in the short-wave infrared (SWIR) and thermal infrared (TIR), was used to characterize the size and intensity of thermal anomalies. Its TIR channels were capable of detecting subtle thermal anomalies. This permitted the observation of new thermal precursors to eruptive events. The Moderate Resolution Imaging Spectroradiometer (MODIS) offers high temporal resolution imagery (i.e. daily global coverage). It was therefore used to investigate thermal activity through time. Wavelet analysis was used to quantify the time period over which such activity oscillates. Hyperion is an orbiting imaging spectrometer. It was used to demonstrate a new method for calculating radiant flux from thermally heterogeneous targets (i.e. such as volcanoes). These methods utilized the strengths of each sensor system, i.e. high spatial, temporal or spectral resolution. They all improve the ability to detect and/or quantify thermal anomalies from space and can be executed in an automated global basis. This thesis therefore presents a solid foundation on which the next generation global volcano monitoring system can be based

Resumo: Um grande esforço tem sido feito para desenvolver sistemas de classificação de imagens capazes de criar mapas temáticos de alta qualidade e estabelecer inventários precisos sobre o uso do solo. As peculiaridades das imagens de sensoriamento remoto (ISR), combinados com os desafios tradicionais de classificação de imagens, tornam a classificação de ISRs uma tarefa difícil. Grande parte dos desafios de pesquisa estão relacionados à escala de representação dos dados e, ao mesmo tempo, à dimensão e à representatividade do conjunto de treinamento utilizado. O principal foco desse trabalho está nos problemas relacionados à representação dos dados e à extração de características. O objetivo é desenvolver soluções efetivas para classificação interativa de imagens de sensoriamento remoto. Esse objetivo foi alcançado a partir do desenvolvimento de quatro linhas de pesquisa. A primeira linha de pesquisa está relacionada ao fato de embora descritores de imagens propostos na literatura obterem bons resultados em várias aplicações, muitos deles nunca foram usados para classificação de imagens de sensoriamento remoto. Nessa tese, foram testados doze descritores que codificam propriedades espectrais e sete descritores de textura. Também foi proposta uma metodologia baseada no classificador K-Vizinhos mais Próximos (K-nearest neighbors - KNN) para avaliação de descritores no contexto de classificação. Os descritores Joint Auto-Correlogram (JAC), Color Bitmap, Invariant Steerable Pyramid Decomposition (SID) e Quantized Compound Change Histogram (QCCH), apresentaram os melhores resultados experimentais na identificação de alvos de café e pastagem. A segunda linha de pesquisa se refere ao problema de seleção de escalas de segmentação para classificação de imagens de sensoriamento baseada em objetos. Métodos propostos recentemente exploram características extraídas de objetos segmentados para melhorar a classificação de imagens de alta resolução. Entretanto, definir uma escala de segmentação adequada é uma tarefa desafiadora. Nessa tese, foram propostas duas abordagens de classificação multiescala baseadas no algoritmo Adaboost. A primeira abordagem, Multiscale Classifier (MSC), constrói um classificador forte que combina características extraídas de múltiplas escalas de segmentação. A outra, Hierarchical Multiscale Classifier (HMSC), explora a relação hierárquica das regiões segmentadas para melhorar a eficiência sem reduzir a qualidade da classificação xi quando comparada à abordagem MSC. Os experimentos realizados mostram que é melhor usar múltiplas escalas do que utilizar apenas uma escala de segmentação. A correlação entre os descritores e as escalas de segmentação também é analisada e discutida. A terceira linha de pesquisa trata da seleção de amostras de treinamento e do refinamento dos resultados da classificação utilizando segmentação multiescala. Para isso, foi proposto um método interativo para classificação multiescala de imagens de sensoriamento remoto. Esse método utiliza uma estratégia baseada em aprendizado ativo que permite o refinamento dos resultados de classificação pelo usuário ao longo de interações. Os resultados experimentais mostraram que a combinação de escalas produzem melhores resultados do que a utilização de escalas isoladas em um processo de realimentação de relevância. Além disso, o método interativo obtém bons resultados com poucas interações. O método proposto necessita apenas de uma pequena porção do conjunto de treinamento para construir classificadores tão fortes quanto os gerados por um método supervisionado utilizando todo o conjunto de treinamento disponível. A quarta linha de pesquisa se refere à extração de características de uma hierarquia de regiões para classificação multiescala. Assim, foi proposta uma abordagem que explora as relações existentes entre as regiões da hierarquia. Essa abordagem, chamada BoW-Propagation, utiliza o modelo bag-of-visual-word para propagar características ao longo de múltiplas escalas. Essa ideia foi estendida para propagar descritores globais baseados em histogramas, a abordagem H-Propagation. As abordagens propostas aceleram o processo de extração e obtém bons resultados quando comparadas a descritores globais
Abstract: A huge effort has been made in the development of image classification systems with the objective of creating high-quality thematic maps and to establish precise inventories about land cover use. The peculiarities of Remote Sensing Images (RSIs) combined with the traditional image classification challenges make RSI classification a hard task. Many of the problems are related to the representation scale of the data, and to both the size and the representativeness of used training set. In this work, we addressed four research issues in order to develop effective solutions for interactive classification of remote sensing images. The first research issue concerns the fact that image descriptors proposed in the literature achieve good results in various applications, but many of them have never been used in remote sensing classification tasks. We have tested twelve descriptors that encode spectral/color properties and seven texture descriptors. We have also proposed a methodology based on the K-Nearest Neighbor (KNN) classifier for evaluation of descriptors in classification context. Experiments demonstrate that Joint Auto-Correlogram (JAC), Color Bitmap, Invariant Steerable Pyramid Decomposition (SID), and Quantized Compound Change Histogram (QCCH) yield the best results in coffee and pasture recognition tasks. The second research issue refers to the problem of selecting the scale of segmentation for object-based remote sensing classification. Recently proposed methods exploit features extracted from segmented objects to improve high-resolution image classification. However, the definition of the scale of segmentation is a challenging task. We have proposed two multiscale classification approaches based on boosting of weak classifiers. The first approach, Multiscale Classifier (MSC), builds a strong classifier that combines features extracted from multiple scales of segmentation. The other, Hierarchical Multiscale Classifier (HMSC), exploits the hierarchical topology of segmented regions to improve training efficiency without accuracy loss when compared to the MSC. Experiments show that it is better to use multiple scales than use only one segmentation scale result. We have also analyzed and discussed about the correlation among the used descriptors and the scales of segmentation. The third research issue concerns the selection of training examples and the refinement of classification results through multiscale segmentation. We have proposed an approach for xix interactive multiscale classification of remote sensing images. It is an active learning strategy that allows the classification result refinement by the user along iterations. Experimental results show that the combination of scales produces better results than isolated scales in a relevance feedback process. Furthermore, the interactive method achieves good results with few user interactions. The proposed method needs only a small portion of the training set to build classifiers that are as strong as the ones generated by a supervised method that uses the whole available training set. The fourth research issue refers to the problem of extracting features of a hierarchy of regions for multiscale classification. We have proposed a strategy that exploits the existing relationships among regions in a hierarchy. This approach, called BoW-Propagation, exploits the bag-of-visual-word model to propagate features along multiple scales. We also extend this idea to propagate histogram-based global descriptors, the H-Propagation method. The proposed methods speed up the feature extraction process and yield good results when compared with global low-level extraction approaches

Electronic devices have acquired an increasingly important role in our society and are integrated in our lives making both the users and their devices more accessible. Currently in the western world most families have at least one computer. This computer is generally equipped with multimedia accessories and an Internet connection. Portable devices, such as mobile phones and PDAs, are part of this technological and social environment. One might think about using a hands free Bluetooth headset together with a mobile phone, to obtain better sound quality, using a keyboard such as the Handykey Corp. Twiddler in order to dial/type quicker or send SMS messages in an easier way, watching a video on a large computer screen that had previously been downloaded to your mobile phone, etcetera. However, there is a problem when it comes to the interconnectivity between all these devices. Today users face many difficulties when attempting to use what should be the aggregated possibilities of their devices, rather than simply the functionality of each device. The hypothesis of this project is that the user's difficulties could be overcome if their devices could be internetworked. For example, even though mobile phones and PDAs often have a USB interface, unlike typical desktop or laptop computers these devices have been designed to only be USB slaves -- hence other USB devices cannot be directly attached to them. There are some signs of this changing with the introduction of USB On-The-Go - but we believe that this is a short-sighted evolutionary step. The obvious solution is to internetwork these devices. For example, by attaching these various USB devices to a computer that is a USB bus master (host) - we can enable the user to use their USB Twiddler with a USB phone. In this way, a user could remotely access the functions of the set of all of their portable devices - without worrying about how to directly interconnect them in pairs. This could enable new functionality, such as the user being able to answer an incoming call to their cellular phone with the keypad of the Twiddler, while using the audio input and output functions of their Bluetooth headset. We begin by examining a number of means to establish and use remote connections to access systems remotely. We have focused on the most popular desktop sharing systems, specifically those that use remote desktop protocols. Initially we require manual configuration or use of a discovery protocol to identify the different devices. Later we will examine additional protocols, along with some potentially automatic configuration mechanisms.Elektroniska apparater har fått en att starkare position i vårt samhälle, integerationen i våra liv gör dem mer tillgängliga. Nu för tiden har de flesta familjer i västvärlden, minst en dator per hushåll. Datorerna har allt som oftast flera multimedia tillbehör och en internett uppkopling. Handhållna aparater så som mobiltelefoner och PDA’er är också en del av teknologiska och sociala miljön. Kanske vill man andvända en handsfree med blue tooth för att förbättra ljudkvaliteten, eller ett tangentbord t.ex. ett Handykey Corp. En twiddler för att ringa eller skicka SMS. Se på högkavitets video på en stor skärm som du tidigare lastat ner till din mobiltelefon, etc. Hur som hälst uppstår det problem vid sammankopplingen mellan olika tillbehör. Dagens användare får en stor utmaning i användade av den kombinerade funktionen i stället för den ensamstående apparatens funktioner och förmåga. Hypotesen av detta projekt är att detta problem kan övervinnas om alla apparater var ihopkoplade via internetwork. Till exempel, även om de flesta mobiltelefoner och PDA’er har USB gränssnitt, har dem tillskillnad från vanliga stationära datorer och laptops bara designats för att vara USB-slavar. Detta betyder att USB-tillbehör inte kan kopplas direkt till apparaten. Det finns tecken på tekniker som t.ex. USB On-The-Go men detta ser ut som en kortsiktig lösning. En uppenbar lösning är att parkoppla dessa apparater via internetwork. Om man t.ex. kopplar alla dessa USB-tillbehör till en stationär eller bärbar dator, kan vi låta användaren komma åt dessa via sin telefon med USB. På så sätt kan användaren trådlöst komma åt alla tillkopplade tillbehör, utan att oroa sig över att para samman dem fysiskt. Möjligheten för nya funktioner och användningsområden visar sig då, som t.ex. att svara på inkommande samtal med den tillkoplade twiddler’n medans samtidigt tala via det trådlösa headsettet. Vi börjar med att undersöka olika tekniker för att upprätta trådlös tillkoppling till olika system. Vi har focuserat på de populäraste datasystemen, framför allt de som använder trådlösa protokoll. Sådana som kräver manuell installation eller använder upptäkande protokoll för att identifiera olika tillbehör. Senare visar vi exempel på andra protokoll med några potensial att automatisk konfigurera tillkopplingen.

Saab has a product, Remote Tower, which allows air traffic controllers to supervise and control an airport remotely. Today an air traffic controller can operate on one airport at the time and switch between airports. The next phase of this system is to allow the air traffic controller to simultaneously control multiple airports, i.e. going from controlling airports in sequence to controlling airports in parallel. The airports are connected to and controlled from one single airport control center. This leads to a planning problem, both in long term and short term, for staffing this airport control center to maintain the capacity of the connected airports. This thesis will present the process of the development of a tool allowing a user to plan the schedule the staffing of a remote tower center. By utilizing this tool the impact of different restrictions affecting the planning will be evaluated and presented in the results.

This thesis proposes strategies for the making and exhibition of films that amplify conservation values and efforts in rural communities. The films support and promote the missions of local leaders and the agendas of respected environmental agencies. The filmmaking strategies entail identifying existing conservation values as experienced through broad themes such as quality of life, economics and community development. By focusing on the collaborative process of making and projecting a film, these strategies serve to inspire innovative solutions promoting responsible stewardship of the land and sea. This model of media creation and delivery is designed to empower local politics and communities with the momentum necessary to plan a future consistent with their environmental values. I call this media creation and delivery strategy, Remote Outreach Cinema Campaigns (R.O.C.C.); Remote, because the media is targeted towards rural audiences, Outreach because the media supports the missions of established environmental agencies, Cinema, because the final delivery is on a large screen and viewed collectively. And Campaign, because the final film is only one part of a process.

Approved for public release; distribution is unlimited.U.S. military and civilian vessels are critically vulnerable to asymmetric threats in littoral environments. Common asymmetric weapons such as Anti-Ship Cruise Missiles (ASCM), Low Slow Flying (LSF) aircraft and Fast Attack Craft (FAC) / Fast Inshore Attack Craft (FIAC) threaten U.S. strategic goals and can produce unacceptable losses of men and material. The SEA-18B team presents an operational concept for a family of Unmanned Surface Vessels USV) capable of defending ships from asymmetric swarm attacks. This USV, the Tailorable Remote Unmanned Combat Craft (TRUCC), can operate in concert with the next generation of capital surface vessels to combat this critical threat with maximum efficiency. Critical performance criteria of the TRUCC family were determined through agent-based simulation of a Straits of Hormuz Design Reference Mission. Additional models addressed ship synthesis and operational availability. A Technology and Capability Roadmap outlines areas of interest for investment and development of the next-generation USV. Interim technology and capability milestones in the Roadmap facilitate incremental USV operational capabilities for missions such as logistics, decoy operations and Mine Warfare. The TRUCC operational concept fills a critical vulnerability gap. Its employment will reduce combat risk to our most valuable maritime assets: our ships and our Sailors.

A remote sensing near infrared suspended sediment algorithm is developed from first principles and applied to Compact Airborne Spectrographic Imagery (CASI) data flown over the Humber Estuary. Laboratory measurements were used as the basis for the algorithm development, with the resulting spectra indicating that the ideal wavelength for a suspended sediment algorithm is the near infrared. The resulting algorithm took the form of a waveband ratio which was subsequently validated with a semi-analytical water optics model based on the absorption/scattering properties of the optically active constituents. The model was then used to derive a global water-leaving radiance algorithm, which is independent of the sediment type. The algorithm was applied to the CASI data collected during August and September 1993, and the resulting SPM maps were compared with contemporaneous in-situ measurements. The in-situ measurements include calculations of the diffuse attenuation coefficient (Kd), which was correlated with the SPM concentration. Further developments to the algorithm through the use of an atmospheric correction are outlined.

This thesis offers a review of the historical development of telemedicine services in remote health care. It addresses the professional concerns in practising medicine in isolated conditions, and the advances in telecommunications technology since the telephone was invented. It also examines the application of telemedicine in remote environments across the world, such as in indigenous communities, remote industrial work sites and at scientific bases in Antarctica. At its most exotic, a review is offered of the health care for space crews. The literature review highlights a number of concerns about the state of the art knowledge on remote health care services. These concerns are the minimal training requirements of individuals who act as health care practitioners in the remote environment, the additional training requirement upon the advising medical practitioner, and the design of a system for the collection of clinical information from the patient. In response to the above a two year study was conducted. Quantitative and qualitative observation of remote health care consultations was undertaken. The environments studied were simulation cases occurring in the UK and Antarctica, and real cases presenting on oil installations in the North Sea. The study results answer the original concerns about the training levels, data collection and communications components of a remote health care service. In addition, they offer valuable input towards the design of a telemedicine model for remote health care. The telemedicine model is presented as a framework upon which future developments in the field of telemedicine may be approached.
