1. 16. Estimating Effective Interactions from Particle Trajectories

   Författare :Kolbjörn Tunström; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mori-Zwanzig projection; Force matching; United atoms; Multi-scale molecular dynamics; Coarse-graining; Molecular dynamics thermostat; Inverse Monte Carlo; Dissipative particle dynamics; Swarming;

   Sammanfattning : The theoretical and practical understanding of molecular systems is strongly dependent on computer simulations. All-atom molecular dynamics techniques are capable of sim- ulating systems on the scale of millions of particles up to about 100 ns. LÄS MER

3. 17. Quantum Few-Body Physics with the Configuration Interaction Approach: Method Development and Application to Physical Systems

   Författare :Jonas Cremon; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tonks-Girardeau gas; vortices; Bose-Einstein condensation; quantum many-particle physics; quantum few-particle physics; Lee-Suzuki approximation; configuration interaction method; Wigner localization; quantum dots; ultra-cold gases; Fysicumarkivet A:2010:Cremon;

   Sammanfattning : This dissertation, based on six included papers, theoretically investigates properties of quantum few-particle systems. An overview of related experimental research - ultra-cold trapped dilute gases, and electrons in quantum dots - is given, followed by a description of some of the studied many-particle phenomena - Bose-Einstein condensation, quantized vortices, Wigner localization and the Tonks-Girardeau gas.

4. 18. Non-Spherical Particle Interaction in Duct and Jet Flow

   Författare :Ammar Hazim; Matthias Mandø; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid-gas flow; turbulence modulation; duct flow; coaxial jets flow; swirl jet flow; active flow control; synthetics jet; biomass powder; non-spherical particles; PIV measurement; Strömningslära; Fluid Mechanics;

   Sammanfattning : Wood waste is the most popular biomass recourse for many nations. Burned wood can, direct or indirect, release one of the greenhouse gases, carbon dioxide. The process can still be seen as a renewable source of energy since replanting of the trees and crops are consuming nearly the same amount of carbon dioxide through photosynthesis. LÄS MER

5. 19. Development and Applications of Detailed Kinetic Models for the Soot Particle Size Distribution Function

   Författare :Karl Netzell; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; flamelet model; Physics; particle distribution; soot; moment method; sectional method; particle size distribution function;

   Sammanfattning : Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective.

7. 20. Microfluidic Cell and Particle Sorting using Deterministic Lateral Displacement

   Författare :Stefan Holm; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Separation science; Deterministic Lateral Displacement; Cell analysis; Deterministic lateral displacement; Microfluidics; Particle sorting; Droplet microfluidics; trypanosomiasis; red blood cell; Cell sorting; Fysicumarkivet A:2018:Holm;

   Sammanfattning : Microfluidics is a field which has the potential to revolutionize medical diagnostics. The ability to sort and analyse cells by the use of portable handheld devices has the potential to enable sensitive devices for point-of-care diagnostics. LÄS MER
