1. 36. Towards a Framework for Efficient Use of Virtual Reality in Urban Planning and Building Design

   Författare :Mikael Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; building design; computer graphics; 3D-city models; Building Information Model; usability; urban planning; Virtual Reality;

   Sammanfattning : This thesis mainly deals with the question on how Virtual Reality (VR) simulations can become a communication tool that is integrated in the urban planning and building design process. The work has investigated both technical and usability aspects of the VR technology and identified challenges encountered when trying to implement VR as a natural communication platform in urban planning and building design.

3. 37. Understanding Physical Reality via Virtual Experiments

   Författare :Sergiu Arapan; Rajeev Ahuja; Börje Johansson; Chris Pickard; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; ab initio calculations; electronic structure; lattice dynamics; high-pressure phase transitions; high-temperature phase transitions; incommensurate structures; Condensed matter physics; Kondenserade materiens fysik;

   Sammanfattning : In this thesis I have studied some problems of condensed matter at high pressures and temperatures by means of numerical simulations based on Density Functional Theory (DFT).The stability of MgCO3 and CaCO3 carbonates at the Earth's mantle conditions may play an important role in the global carbon cycle through the subduction of the oceanic crust.

4. 38. Datadriven Human Intention Analysis : Supported by Virtual Reality and Eye Tracking

   Författare :Julius Pettersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; eye tracking; Virtual reality VR ; deep machine learning; time series analysis; psychological testing.; collaborative robots; human intention prediction; uncertainty estimation;

   Sammanfattning : The ability to determine an upcoming action or what decision a human is about to take, can be useful in multiple areas, for example in manufacturing where humans working with collaborative robots, where knowing the intent of the operator could provide the robot with important information to help it navigate more safely. Another field that could benefit from a system that provides information regarding human intentions is the field of psychological testing where such a system could be used as a platform for new research or be one way to provide information in the diagnostic process.

5. 39. Application of Virtual Reality in the study of Human Behavior in Fire : Pursuing realistic behavior in evacuation experiments

   Författare :Silvia Arias; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Virtual Reality; behavioral realism; fire evacuation; VR experiments;

   Sammanfattning : Virtual Reality (VR) experiments are used to study human behavior in fire because they allow simulation of fire events with relatively low risks to the participants, while maintaining high levels of experimental control. Manystudies have used VR experiments to explore aspects of the human response to fire threats, but VR experiments as a research method are yet to be subjected to a systematic process of validation.

7. 40. Construction, Validation and Application of a Virtual Reality Simulator for the Training of Transurethral Resection of the Prostate

   Författare :Reidar Källström; Joar Svanvik; Hans Hjertberg; Peder Funch-Jensen; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgical education; simulation; transurethral resection of prostate; psychometric tests; personality; validation; virtual reality; proficiency based training; objective assessment; MEDICINE; MEDICIN;

   Sammanfattning : The fundamental of surgical training is the traditional apprenticeship method introduced by William Halsted which has been used for the last 100 years. It is based on learning in the operating room (OR) where the resident is guided by an experienced surgeon and gradually and methodically exposed to surgery. LÄS MER
