1. 11. From Static Structures to Free Energy Landscapes: Characterizing Conformational Transitions in Biological Macromolecules

   Författare :Cathrine Bergh; Erik Lindahl; Gerhard Hummer; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein conformational transitions; molecular dynamics simulations; statistical mechanics; ion channels; Proteinkonformationsövergångar; molekyldynamiksimuleringar; statistisk mekanik; jonkanaler;

   Sammanfattning : To be alive means to temporarily counteract the fundamental dispersive driving force described by the second law of thermodynamics, eventually leading all systems to decay and disorder. In cells, this task is partly carried out by proteins - small specialized molecular machines that utilize free energy to maintain the proper functioning of the cell. LÄS MER

3. 12. Potential for B-physics measurements with a fixed-target proton-collision experiment

   Författare :Jenny Ivarsson; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; CP Violation; quantum field theory; Elementarpartikelfysik; HERA-B; Fixed Target; kvantfältteori; B Physics; Monte Carlo Simulations; Fysicumarkivet A:1999:Ivarsson;

   Sammanfattning : HERA-B is a high-energy physics experiment at HERA. It is a fixed-target experiment with a forward spectrometer to benefit from the strong boost of beauty hadrons. The main goal of HERA-B is to detect and measure the degree of CP violation in exclusive B-decays, with emphasis on the {em golden} decay, $golden$. LÄS MER

4. 13. Co-Simulation of Coupled Electromagnetic and Nonlinear Circuit Problems using the Partial Element Equivalent Circuit Method

   Författare :Sohrab Safavi; Wil Schilders; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Sammanfattning : Co-simulation of coupled electromagnetic (EM) structures and linear/nonlinear circuits has become a major demand in today's engineering. In many disciplines such as antenna engineering, microwave circuit design, electromagnetic compatibility (EMC), and even fairly low-frequency power electronic systems, simulation techniques capable of incorporating both EM structures and lumped circuit elements have become a necessity.

5. 14. The partial element equivalent circuit method : modeling and experimental verification of PCB structures

   Författare :Jonas Ekman; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Sammanfattning : To help products comply with international Electromagnetic Compatibility (EMC)regulations or as a help in a design process numerical simulation of electromagnetic (EM) characteristics are a valuable tool. With the development of high-speed computers the complexity of EM simulation programs and the systems they can simulate has increased considerable. LÄS MER

7. 15. Efficient PEEC-based solver for complex electromagnetic problems in power electronics

   Författare :Danesh Daroui; Bruce Archambeault; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Sammanfattning : The research presented in this thesis discusses an electromagnetic (EM) analysis tool which is based on the partial element equivalent circuit (PEEC) method and is appropriate for combined EM and circuit simulations especially power electronics applications. EM analysis is important to ensure that a system will not affect the correct operation of other devices nor cause interference between various electrical systems. LÄS MER
