A Unifying Interface Abstraction for Accelerated Computing in Sensor NodesIyer, Srikrishna 31 August 2011 (has links)
Hardware-software co-design techniques are very suitable to develop the next generation of sensornet applications, which have high computational demands. By making use of a low power FPGA, the peak computational performance of a sensor node can be improved without significant degradation of the standby power dissipation. In this contribution, we present a methodology and tool to enable hardware/software co-design for sensor node application development. We present the integration of nesC, a sensornet programming language, with GEZEL, an easy-to-use hardware description language. We describe the hardware/software interface at different levels of abstraction: at the level of the design language, at the level of the co-simulator, and in the hardware implementation. We use a layered, uniform approach that is particularly suited to deal with the heterogeneous interfaces typically found on small embedded processors. We illustrate the strengths of our approach by means of a prototype application: the integration of a hardware-accelerated crypto-application in a nesC application. / Master of Science

7 visioner för framtidens BIM : En studie kring vilka förändringar som krävs för att skapa ett branschvägledande arbetssätt för användandet av BIM / 7 visions for the future of BIM : A survey of the neccessary changes to create an industry-guiding way of working with the application of BIMAndersson, Jonathan, Hällgård, Johan January 2015 (has links)
Molnlagring, kommunikationsplattformar med interaktiva funktioner, virtuella modeller som sammanfogas med fysiska omgivningar, datorsimuleringar, livscykelperspektiv. Så diskuteras det i BIM-världens korridorer. Men om detta nu är framtiden: varför går implementeringen så långsamt, och vad är det egentligen som ska implementeras? Processen att hantera och förstå vad BIM är har blivit för komplex, och med denna rapport vill vi hitta åtgärder för att göra arbetssättet begripligt och användbart för fler. Vi har i samarbete med Vianova Systems undersökt hur användningen av BIM ser ut idag och vilka förbättringsåtgärder som behövs för en bredare framtida implementering i samhällsbyggnadsbranschen. Våra undersökningar visar att nästan 80 % tror att ett arbete som drar nytta av en digital modell skulle vara effektivare: samtidigt är osäkerheten kring mjukvaror och oklarhet kring implementeringen av arbetsmetoderna begränsande faktorer. Som lösning på detta har ett användarinterface för projektsamordning och kommunikation arbetats fram. Dessa undersökningar har genomförts med hjälp av en enkätstudie samt intervjuer och sammanställts i två delar: dels denna rapport, samt en slutprodukt av visionär karaktär kallad ”7 visions for the future of BIM”. / Cloud storage, communication platforms with interactive functions, virtual models that are merged with physical surroundings, computer simulations, life cycle perspective. This is what is being discussed in the corridors of the BIM-world. But if this is the future: why is the implementation so slow, and what exactly is to be implemented? The process of handling and understanding what BIM is has become too complex, and in this report we want to find solutions for making the way of working intelligible and useful for a wider audience. In collaboration with Vianova Systems, we have investigated what the use of BIM looks like today and what improvements are needed for a wider future implementation in the AEC industry. Our investigations show that almost 80 % believe that work which utilizes a digital model would be more effective: at the same time the insecurity concerning software and uncertainties regarding the implementation of the work methodologies are limiting factors. As a solution for this a user interface for project management and communication has been developed. These investigations have been carried out with the aid of a questionnaire and interviews and compiled into two parts: partly this report, as well as an end product of visionairy nature called ”7 visions for the future of BIM”.

PDA software pro robotický fotbal / PDA software for robot soccerUhlíř, Luděk January 2008 (has links)
Robotic soccer is a game like a real soccer but here the game is played by robots. The rules are the same, only there are few exceptions (foul, penalty kick, stalemate situation). Game is running without the human intervention. Just a human referee is supervising the game. Two teams are attending the game. Each of them has a control computer. The control computer is the brain of the game. It has a camera, it is making decisions for the next step of robots and sending them configuration data. The thesis deals with testing of communication interface and designs the new communication protocol for the next generation of the robots. The testing is provided by pocket pc Palm TX. It will send data over the Bluetooth interface to the control pc and will configure particular constants, like constants of PID regulator and an address of a robot. This will be provided by the IrDA interface.
