2. 6. Modelling and Analysis of Interconnects for Deep Submicron Systems-on-Chip

   Author : Dinesh Pamunuwa; KTH; []
   Keywords : delay and noise modelling in VLSI circuits; cross-talk; interconnect modelling; timing analysis; transfer function; on-chip bus; bandwidth maximization; throughput maximization; repeater insertion; wire optimization;

   Abstract : The last few decades have been a very exciting period in thedevelopment of micro-electronics and brought us to the brink ofimplementing entire systems on a single chip, on a hithertounimagined scale. However an unforeseen challenge has croppedup in the form of managing wires, which have become the mainbottleneck in performance, masking the blinding speed of activedevices. READ MORE

4. 7. Modelling and control of a line-commutated HVDC transmission system interacting with a VSC STATCOM

   Author : Paulo Fischer de Toledo; Hans-Peter Nee; Gustaf Ohlsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Keywords : HVDC transmission; LCC – Line-commutated Current-source Converter; STATCOM; VSC – Voltage Source Converter; Space-Vector complex vector ; transfer-function; frequency-domain analysis; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Abstract : The interaction of an HVDC converter with the connected power system is of complex nature. An accurate model of the converter is required to study these interactions. The use of analytical small-signal converter models provides useful insight and understanding of the interaction of the HVDC system and the connected system components. READ MORE

5. 8. Methods to Generate Size- and Composition Controlled Aerosol Nanoparticles

   Author : Martin Karlsson; Fasta tillståndets fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; differential mobility analyzer DMA ; transfer function; binary alloy nanoparticles; nanoparticle generator; thermal decomposition; Physics; sintering; Fysik; size selection; nanoparticles; aerosol technology; Fysicumarkivet A:2004:Karlsson;

   Abstract : This thesis describes experiments performed using different methods to produce aerosol nanoparticles with control over size and composition. The process included differential mobility analyzers (DMAs) as size-selecting instruments and tube furnaces for particle synthesis. READ MORE

6. 9. Modeling and Control of Voltage Source Converters Connected to the Grid

   Author : Michael Lindgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage source converter; switching frequency; pulse width modulation; IGBT valve; power electronics; small-signal; L-filter; LCL-filter; transfer function; line filter; active filtering; frequency response; sampling frequency;

   Abstract : This thesis deals with the modeling and control of pulse width modulated (PWM) voltage source converters connected to the grid. When voltage source converters are connected to the grid, the power quality and the dynamic performance are affected by the line filter connected between the converter and the grid, and by nonlinearities caused by the switching converter.

7. 10. Efficient Medical Volume Visualization : An Approach Based on Domain Knowledge

   Author : Claes Lundström; Anders Ynnerman; Hans Knutsson; Dirk Bartz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scientific Visualization; Medical Imaging; Computer Graphics; Volume Rendering; Transfer Function; Level-of-detail; Fuzzy Classification; Uncertainty Visualization; Virtual Autopsies; Medical engineering; Medicinsk teknik;

   Abstract : Direct Volume Rendering (DVR) is a visualization technique that has proved to be a very powerful tool in many scientific visualization applications. Diagnostic medical imaging is one domain where DVR could provide clear benefits in terms of unprecedented possibilities for analysis of complex cases and highly efficient work flow for certain routine examinations.
