1. 21. An industrial robot as carrier of a laser profile scanner : motion control, data capturing and path planning

   Författare :Sören Larsson; Johan Kjellander; Wolfgang H. Koch; Örebro universitet; []
   Nyckelord :Geometric reverse engineering; Laser scanning; Industrial robot; Path planning; CAD; 3D measurement systems; Mechanical engineering; Maskinteknik; TECHNOLOGY; TEKNIKVETENSKAP; Mechanical Engineering; Maskinteknik;

   Sammanfattning : Geometric Reverse Engineering (RE) is concerned with the problem of creating CAD-models of real objects by measuring point data from their surfaces. In the aim of creating a fully automatic RE system there is a need to automate also the measuring process. LÄS MER

3. 22. Tomographic Techniques for Safeguards Measurements of Nuclear Fuel Assemblies

   Författare :Tobias Lundqvist Saleh; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : Nuclear power is currently experiencing increased interest over the world. New nuclear reactors are being built and techniques for taking care of the nuclear waste are being developed. This development puts new demands and standards to safeguards, i.e. LÄS MER

4. 23. Electronic Properties of Diamond

   Författare :Markus Gabrysch; Jan Isberg; Mats Leijon; Johan Hammersberg; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; CVD diamond; wide-bandgap semiconductor; time-of-flight; pair-creation energy; electronic devices; detector; Elektronik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

   Sammanfattning : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties compared to other (wide bandgap) semiconductors make it desirable to develop single-crystalline epitaxial diamond films for many electronic device and detector applications.

5. 24. Microwave Transistor Noise Model Extraction Methods and a Non-Contacting Scattering Parameter Measurement Method

   Författare :Jörgen Stenarson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extraction; S-parameter; noise parameter; vector network analyzer; electro-magnetic probe; microwave; non-contacting testing; transistor noise model; VNA; EM-probe; non-invasive testing;

   Sammanfattning : This thesis has two parts. The first part discuss noise model extraction methods for FETs. The second part describe theory and implementation of a non-contacting S-parameter measurement method. Noise is an important aspect for a circuit designer, because noise generated in the circuit is a sensitivity limiting factor. LÄS MER

7. 25. Viscous Behaviour of Fibre-filled Liquids

   Författare :Mina Djalili-Moghaddam; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viscosity; geometry effects; short-range interactions; parallel plate; fibre suspension; normal force; cone and plate;

   Sammanfattning : Process simulation of discontinuous fibre composites is of importance in automotive industries. The performance of a fibre composite part depends to a great extent on the fibre orientation pattern. LÄS MER
