1. 16. Simulation supported training in oral radiology : methods and impact on interpretative skill

   Författare :Tore Nilsson; Jan Ahlqvist; Martin Rydmark; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virtual reality; simulation; simulator; radiology; radiography; learning; skill acquisition; visual-spatial ability; parallax; Radiology; Radiologi; odontologi; Odontology;

   Sammanfattning : Simulation is an important tool when training is hazardous, time consuming, or expensive. Simulation can also be used to enhance reality by adding features normally not available in the real world. LÄS MER

3. 17. A real-time simulation-based optimisation environment for industrial scheduling

   Författare :Marcus Frantzén; Philip Moore; David Stockton; Amos Ng; Stephen Newman; Riham Khalil; Högskolan i Skövde; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheduling system; Simulation; Scheduling; simulation-based optimisation; Technology; Teknik; Production and Automation Engineering; Produktion och automatiseringsteknik;

   Sammanfattning : In order to cope with the challenges in industry today, such as changes in product diversity and production volume, manufacturing companies are forced to react more flexibly and swiftly. Furthermore, in order for them to survive in an ever-changing market, they also need to be highly competitive by achieving near optimal efficiency in their operations. LÄS MER

4. 18. Electrothermal Simulation in a Concurrent Waveform Relaxation Based Circuit Simulator

   Författare :Magnus Wiklund; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circuit synthesis; Bond graphs; Nullor; Circuit theory; Analog simulation; Circuit simulation; Multiprocessor computer; CONCISE; Parallel computation; Waveform relaxation; Thermal models; Transistor models; Electro-thermal simulation; Electro-thermal modeling; Translinear circuits; Electronics; Elektronik; Electrical engineering; Elektroteknik;

   Sammanfattning : The main purpose of this work is to study methods to simulate electro-thermal effects in integrated circuits using CONCISE a waveform relaxation based circuit simulator. WR is a method that is suitable to run on a multi-computer with state of the art computing power. Especially CMOS VLSI circuits have been simulated successfully with WR. LÄS MER
