2. 1. Electronic Healthcare Ontologies : Philosophy, the real world and IT structures

   Author : Martin Berzell; Ingemar Nordin; Urban Forsum; Daniel Karlsson; Ingvar Johansson; Linköpings universitet; []
   Keywords : HUMANIORA; HUMANITIES; Philosophy; medical informatics; ontology; terminology; critical realism; immanent realism; Filosofi; medicinsk informatik; ontologi; terminologi; kritisk realism; immanent realism; Theory of science; Vetenskapsteori; Theoretical philosophy; Teoretisk filosofi;

   Abstract : The thesis investigates how the notion of ‘ontology’ has been used in the field of medical informatics and knowledge representation. Partly to investigate what an ‘ontology’ can be said to represent and what requirements we can have on a good ‘ontology’. READ MORE

4. 2. Consensus Trade-offs in Wireless Sensor Networks

   Author : CHRISTOPHER LINDBERG; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Algorithms; Wireless Sensor Networks; Compressed Sensing; Consensus Algorithms; Trade-off Analysis;

   Abstract : As more and more everyday electronic devices become equipped with the combined re- sources of computation, sensing, and wireless communications, possible platforms for implementation of wireless sensor networks have become ubiquitous. The combination of these three main capabilities of such a network present the opportunity to for example gather high resolution measurement data, or cooperatively perform advanced computa- tional tasks.

7. 5. Photonic THz Generation and Quasioptical Integration for Imaging Applications

   Author : Biddut Kumar Banik; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nondestructive evaluation; semiconductor device modelling; uni-travelling-carrier photodiodes; millimetre wave and submillimetre wave generation; III-V semiconductors; photomixers; terahertz sources.; catadioptric lens; microwave imaging; dielectric loaded antennas; terahertz imaging; lens antennas; millimetre wave and submillimetre wave imaging;

   Abstract : This thesis deals with the analysis and optimisation of the uni-travelling-carrier photodiode (UTC-PD) for continuous-wave generation in terahertz (THz) frequencyrange. Photonic THz generation using UTC-PDs is extremely promising as it offers wide tunability, adequate output power and room temperature operation. READ MORE
