A PC-BASED RF TEST CONSOLE FOR INTEGRATION & TEST ON NASA’S LUNAR PROSPECTOR SPACECRAFT

Losik, Len 10 1900 (has links)
International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Lunar Prospector’s project engineering staff selected a Windows PC platform as the RF test console for the Lunar Prospector spacecraft. The spacecraft test team chose the PCbased RF test console because the PC provides a low-cost, common platform with a graphical user interface. The PC provides point-and-click, menu-driven windows that are common throughout the satellite factory. The PC RF test console is being used to exercise the Lunar Prospector spacecraft RF link for RF commanding, telemetry, and ranging signals during factory test, including thermal vacuum chamber testing. For spacecraft command and control at the factory, the PC-based RF test console is networked to a UNIX workstation over RS-422. The PC RF test console and spacecraft interface are controlled through a coax switch residing in a test rack next to the workstation. The PC RF test console is connected directly to the Lunar Prospector spacecraft using coax cable through the spacecraft Telemetry, Commanding, & Ranging (TC&R) RF antenna hat for both transmit and receive functions. The PC RF test console is also connected hard-line to the spacecraft transponder through the transponder RS-422 connection. This connection provides the ability for spacecraft telemetry to be received at the PC at RF or baseband. The same hard-line spacecraft telemetry data is provided to the UNIX workstation for comparison. NASA’s Lunar Prospector project is the first of the Discovery series of “faster, better, cheaper” missions to be competitively awarded. Lunar Prospector project funding was capped by NASA to ensure that no overruns would occur. The mission was funded to support the scientific community’s desire to verify the presence of ice on the moon and collect environmental data to understand the dynamics that may have led to polar ice deposits. The Lunar Prospector mission received funding in 1996 with a launch planned for September 1997

Les interventions thérapeutiques dans les pathologies inflammatoires et le cancer : compréhension des propriétés immunomodulatrices de Viscum album / Therapeutic intervention in inflammatory pathologies and cancer : understanding the anti-inflammatory properties of Viscum album

Hegde, Pushpa 26 June 2013 (has links)
Les progrès réalisés en immunologie ont orienté les recherches vers des approches et des stratégies de plus en plus prometteuses et innovantes afin de mieux manipuler la réponse immunitaire. Le but de nos recherches est la prévention et le traitement des maladies liées aux dysfonctionnements du système immunitaire, telles que les maladies auto-immunes, inflammatoires et malignes. Bien que l’inflammation constitue un processus physiologique indispensable au maintien de l’homéostasie suite à une infection ou à une lésion, elle est également associée à des pathologies infectieuses, auto-immunes et tumorales. Les stratégies thérapeutiques les plus utilisées pour traiter l’inflammation sont basées sur la neutralisation des médiateurs inflammatoires par des anticorps, des antagonistes moléculaires, des immunoglobulines intraveineuses, des corticostéroïdes, des médicaments anti-inflammatoires non stéroïdiens. En plus des traitements mentionnés, des produits issus de la phytothérapie ont été largement utilisés afin d’atténuer l'inflammation et la douleur dans plusieurs maladies inflammatoires et dans le cancer. Depuis des décennies, les préparations de Viscum album, connu sous le nom de « gui européen », sont largement utilisées dans le traitement du cancer comme thérapie auxiliaire. Bien que les mécanismes d’action soient partiellement connus, plusieurs hypothèses ont été proposées. En effet, les mécanismes anti-tumoraux du Viscum album impliquent des propriétés induisant une cytotoxicité, l'apoptose, l'inhibition de l'angiogenèse et plusieurs autres mécanismes immunomodulateurs. Ce travail décrit un nouveau mécanisme anti-inflammatoire de Viscum album, qui participe à l’effet thérapeutique de ces préparations. De plus, l’effet bénéfique anti-inflammatoire observé est associé à l’inhibition des voies pro- inflammatoires de COX2 et PGE2 dans les cellules épithéliales issues d’adénocarcinome du poumon. Ce travail a identifié un des mécanismes moléculaires de Viscum album associé à son effet anti-inflammatoire participant à ses bénéfices thérapeutiques. Ainsi, ces préparations pourraient être utilisées en combinaison avec d’autres traitements dans des maladies inflammatoires et dans le cancer. / Recent advances in immunology research have led us towards more promising approaches and strategies to manipulate the immune response to prevent or treat the diseases related to immune dysfunction such as autoimmune, inflammatory pathologies and malignant diseases. Although, immuno inflammation is a basal physiological phenomenon required to eliminate the causative agent and to initiate the healing process, it is a physiopathological symptom in a diverse conditions of infectious, autoimmune and tumoral origin. Various therapeutic strategies have been developed in order to reduce inflammation and pain, including the treatment with cytokine neutralizing antibodies, molecular antagonists, intravenous immunoglobulins, corticosteroids, non-steroid anti-inflammatory drugs (NSAID) and several others. In addition to these well known anti-inflammatory therapeutic strategies, treatment with various phytotherapeutics has also contributed enormously to control inflammation and pain, associated with various severe inflammatory disorders and cancer. Viscum album (VA) preparations, commonly known as European mistletoe, are extensively used as complementary therapy in cancer for decades. However the mechanisms of action have been partially understood. Several mutually non-exclusive mechanisms have been proposed such as anti-tumor properties which involve the cytotoxic properties, induction of apoptosis, inhibition of angiogenesis and several other immunomodulatory mechanisms. This study reveals anti-inflammatory mechanism as another important mechanism of action of these phytotherapeutics, which is responsible for their therapeutic benefit and addresses the molecular mechanisms in the pro-inflammatory axis of COX-2 and PGE2 using in vitro experimental model of human lung adenocarcinoma. The present work contributes for a better understanding of mechanisms of action of Viscum album preparations underlying their therapeutic benefit and allows us to revitalize the therapeutic strategies used in treatment of inflammatory disorders and cancer.

Vad krävs för att beräkna när automatiserade användargränssnitt (GUI) tester lönar sig? : Vilka styrkor och svagheter finns med automatiserade GUI-test? / What is required in order to calculate when the automated user interface (GUI) testing is worthwhile?

Vikström, Todd, Kaiser Löv, Sara January 2019 (has links)
ROI och break-even finns för att beräkna vinster i verksamheter men det är svårt att veta hur dessa metoder kan appliceras på automatiserade GUI-test. Genom en utförd fallstudie där litteraturstudier, dokumentstudier, enkäter och intervjuer använts har det visat sig att dessa metoder kan anpassas för att beräkna vinster med automatiserade GUI-tester. Nackdelarna med dessa metoder är att de är svåra att använda om inte automatiseringen är gjord. Det behövs konkreta uppgifter över till exempel tidsåtgång för körning av både manuella och automatiserade testfall. Även om metoderna kan visa att det finns ekonomiska vinster med automatiserade GUI-tester så kan det vara många andra vinster som inte kan identifieras genom att metoderna appliceras. Dessa immateriella vinster och förluster har i arbetat identifierats genom intervjuer och enkäter och resultatet presenteras med en SWOT-analys. Flera viktiga immateriella vinster som till exempel ökad kvalitet och tidsvinst har framkommit. Även några materiella förluster har framkommit som att det kan vara kostsamt att införa automatiserade GUI-tester. Även immateriella förluster har identifierats, en av dessa är att det krävs särskild kompetens för att konstruera och köra de automatiserade testerna. / ROI and break-even are available for calculating profits in operations, but it is difficult to know how these methods can be applied to automated GUI tests. By a conducted case study in which literature review, document studies, questionnaires and interviews have been used, it has been shown that these methods can be adapted to calculate the profits with automated GUI-tests. The disadvantages with these methods are that they are difficult to use unless the automation is made. There is a need for concrete data on, for example, the time taken for the execution of both manual and automated test cases. Although the methods can show that there are financial gains with automated GUI tests, there may be many other gains that cannot be identified by applying the methods. These intangible profits and losses have been identified in the work through interviews and surveys and the results are presented with a SWOT analysis. Several important intangible benefits such as increased quality and time savings have emerged. Some material losses have also come to light as it can be costly to introduce automated GUI tests. Even intangible losses have been identified, one of these is that it requires special skills to design and run the automated tests.

Design de interação para TV Digital: convergência das mídias e o Sistema Brasileiro de TV Digital / Digital TV Interaction Design: media convergence and the Brazilian Digital Television System

Schlittler Silva, João Paulo Amaral 27 April 2011 (has links)
O Sistema Brasileiro de TV Digital (SBTVD), adotado como padrão de TV Digital no Brasil, traz consigo a alta resolução de imagens, mais canais, a transmissão para receptores móveis e a promessa de interatividade. Concomitantemente à sua implantação, vemos o crescimento da base de usuários do serviço móvel pessoal, assim como um aumento substancial dos usuários de redes sociais e da internet acessando mídias como TV, música, publicações e conteúdo gerado por usuários. As mídias digitais interativas criaram uma demanda pelo design de interfaces facilitadoras da interação entre máquinas, usuários e o acesso, busca e distribuição de conteúdo midiático. Designers gráficos antes dedicados a mídias específicas como a TV, cinema e publicações impressas têm migrado para plataformas digitais, contribuindo para o design de mundos virtuais e a interação homem-computador. Com a convergência da TV Digital com outras mídias, designers de interfaces devem considerar a ubiquidade de dispositivos móveis inteligentes presentes no mesmo ambiente da TV, criando assim uma experiência em que os usuários podem interagir com múltiplas telas e plataformas. É cada vez mais comum celulares e outros aparelhos portáteis estarem conectados à internet, e que podem servir como canal de retorno e tela secundária, expandindo a interface do usuário e facilitando a interação com a TV. Diversos motivos como a ausência de um canal de retorno e a disponibilidade limitada do middleware Ginga em conversores e receptores de TV Digital têm atrasado o lançamento de serviços interativos para o SBTVD. Ao transferir o paradigma da interatividade de um modelo de distribuição vertical para um ambiente conectado, no qual usuários e telespectadores podem compartilhar sua experiência em múltiplas telas e dispositivos, é possível conceber uma nova forma de interação com a TV Digital. Esta tese pesquisa avanços no design de interfaces, tecnologia da TV Digital e novas mídias de modo a subsidiar o design de experiência do usuário da TV Digital. Partindo do conteúdo audiovisual e digital da Copa do Mundo de 2010, propõe-se o design de uma interface que integra um smartphone com um receptor de TV Digital como síntese de um modelo de interação com a TV para a Copa de 2014. / While Brazil has adopted SBTVD as its Digital Television standard, providing higher resolution, multiple channel feeds, mobile television and the promise of interactivity, there has been an explosive growth of the cell phone user base, as well as a dramatic increase in the usage of social networks and services on the internet that provide access to digital media such as TV, music, publishing and user generated content. The emergence of digital media has created a demand for the design of humancomputer interfaces allowing the interaction between users, searching, publishing and retrieving media content. Graphic designers once working on specific medias such as print, film and television have migrated to digital platforms becoming more and more involved in the design of virtual worlds and human computer interaction. As Digital TV converges with other media, user interface designers should consider the ubiquity of digital devices in the same room as an HDTV receiver, creating an experience where users can fluidly interact with multiple platforms and screens. Increasingly smartphones and other devices are connected to the internet, thus providing both a data return path and a secondary display that can extend the user interface enhancing the interaction with the TV. For several reasons, such as the lack of a return path and limited availability of Ginga middleware in converter boxes and digital sets, the launch of Interactive TV services has had a slow start in Brazil. By shifting the paradigm of interactivity from a vertical distribution model to a connected environment where users and viewers can share their experiences using multiple screens and devices, it is possible to design a new way to experience and interact with Digital TV. This thesis researches developments in interface design, digital TV technology and new media in order to subsidize the design of an interactive TV user experience. Drawing on audiovisual media and interactive content of the 2010 FIFA World Cup, the design of a user interface that integrates a smartphone with a DTV Receiver proposes a DTV interaction model for the 2014 World Cup.

Interactive Visualization of Statistical Data using Multidimensional Scaling Techniques

Jansson, Mattias, Johansson, Jimmy January 2003 (has links)
<p>This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. </p><p>In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. </p><p>In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize. </p><p>Together with Dr. Robert Treloar at Unilever, the SOM Visualizer - an application for interactive visualization and analysis of multidimensional data - has been developed. The analytical part of the application is based on Kohonen’s self-organizing map algorithm. In cooperation with the Smartdoc project, a component has been developed that is used for smart filtering in multidimensional data sets. Microsoft Visual Basic and components from the graphics library AVS OpenViz are used as development tools.</p>

Construction and realisation of measurement system in a radiation field of 10 standard suns.

Makineni, Anil Kumar January 2012 (has links)
A measurement system is to be presented, which is used to obtain the I-V characteristics of a solar cell and to track its temperature during irra-diation before mounting it into a complete array/module. This project presents both the design and implementation of an Electronic load for testing the solar cell under field conditions of 10000 W/m^2, which is able to provide current versus voltage and power versus voltage charac-teristics of a solar cell using a software based model developed in Lab-VIEW. An efficient water cooling method which includes a heat pipe array system is also suggested. This thesis presents the maximum power tracking of a solar cell and the corresponding voltage and current values. In addition, the design of the clamp system provides an easy means of replacing the solar cell during testing.Keywords: Solar cell, Metal Oxide Semiconductor Field Effect Transistor (MOSFET), I-V characteristics, cooling system, solar cell clamp system, LabVIEW, Graphical User Interface (GUI).

The body concept intelligentsia of the Wei-Jin Dynasty

Wang, Hsiu-Lin 14 August 2006 (has links)
Through the triple changes which include the variation in society, time and space, the intelligentsia in Wei and Jin Dynasties came to a realization that life is capricious. They combined the thought of Tze-Shi (carefree and footloose) and Gui-wuo (emphasize the unique value of oneself) together with the tolerance of physical desire and worship of nature to develop two theories: Zhong-shen (consider body as the foundation of all) and Le Sheng (carpe diem/seize the day), which remain the keynote of the viewpoint towards body in Wei and Jin Dynasties. Wei and Jin Dynasties followed the theory of Chi-transformation in Han Dynasty, as well as the idea that form and spirit are one, and develop a complete viewpoint towards body which interprets body and mind as one unity. The Chi flows in the body and becomes the medium of body and mind, then goes outward to the relation between body and nature; human body itself forms a complete micro system, which, through the flow of emotion and Chi, echoes or responds with the macro system of nature. The intelligentsia in Wei and Jin Dynasties considered etiquette and music as the embodiment of nature and human body as the territory where culture and nature are embodied. Kuo-Shian interpreted the relation between body, etiquette and music with the theory of Shi-Jai-Ti-Chung (ease and comfort within the body). Etiquette and music was made in a situation in which ¡§ease and comfort¡¨ are in harmony with body and also communicate with the heaven, earth and man in a way that ¡§ease and comfort¡¨ harmonize with the nature, and brings heaven, earth and man in concordance. When etiquette fails to bring ¡§ease and comfort¡¨ to the body, the intelligentsia used body as a tool to fight against the rigid etiquette, in order to arouse introspection over Li-Yuan-Zen-Ching (etiquette should be made with human beings as the first consideration, and eschews rigidity or affectation), and at the meantime brings reformation and feedback to the society. The intelligentsia¡¦s rising consciousness of selfhood and body makes the relation between body and society an active instead of a passive one. The intelligentsia, while perceiving the change of society and understanding the fact that human nature is unalterable, were contented to remain the status as Chung-Zen (mediocrity, people who are between genius and fools), and pursuit the fulfillment of their dreams as well as the feeling of carefree. Those intelligentsia emphasized the value of themselves and preferred to be themselves while understanding completely the truth and limitation of life, and they responded changes of the society and time with the idea of Shi-Shin-An-Min (follow and accept your own nature, be contented).

Dynamically generated multi-modal application interfaces / Dynamisch generierte multimodale Anwendungsschnittstellen

Kost, Stefan 28 May 2006 (has links) (PDF)
This work introduces a new UIMS (User Interface Management System), which aims to solve numerous problems in the field of user-interface development arising from hard-coded use of user interface toolkits. The presented solution is a concrete system architecture based on the abstract ARCH model consisting of an interface abstraction-layer, a dialog definition language called GIML (Generalized Interface Markup Language) and pluggable interface rendering modules. These components form an interface toolkit called GITK (Generalized Interface ToolKit). With the aid of GITK (Generalized Interface ToolKit) one can build an application, without explicitly creating a concrete end-user interface. At runtime GITK can create these interfaces as needed from the abstract specification and run them. Thereby GITK is equipping one application with many interfaces, even kinds of interfaces that did not exist when the application was written. It should be noted that this work will concentrate on providing the base infrastructure for adaptive/adaptable system, and does not aim to deliver a complete solution. This work shows that the proposed solution is a fundamental concept needed to create interfaces for everyone, which can be used everywhere and at any time. This text further discusses the impact of such technology for users and on the various aspects of software systems and their development. The targeted main audience of this work are software developers or people with strong interest in software development.
