Explorable Explanations on Statistical Physics
Examensarbete på avancerad nivå, 2016 (MSc - Complex adaptive systems)
This thesis report describes the development of Many Tiny Things, a series of explorable explanations on basic statistical physics. The explanations guide the reader through a molecular dynamics model, which is simulated and visualised on the reader’s computer. The reader can interact with the simulated model, and explore concepts such as energy, temperature...
On improving the expressive power of chemical computation
Examensarbete på avancerad nivå, 2015 (MSc - Complex adaptive systems)
Traditional CMOS computers are Turing complete information processing systems. They can compute any function that can be described algorithmically. In the past, the computing speed of such systems has been constantly improved. However, for various technological reasons this trends is expected to stop, and alternative ways of computing are under investigation...
General Analytical Solution for Two-group, Two-point Variance-to-mean Formulas and Their Application to Safeguards
Examensarbete på avancerad nivå, 2013 (MSc - Nuclear Engineering)
The theory of Feynman-alpha method was extended to two-point one-group, two-group onepoint,and two-point two-group versions by using the Kolmogorov forward master equation withcomplete description of various types of reactions for neutrons. The motivation for this workis related to the fact that the traditional one-group one-region Feynman-alpha formula wase...
One-shot free energy calculations for crystalline materials
Examensarbete på avancerad nivå, 2012 (Masterarbete)
Current methods for free energy calculations in materials science are either computationally expensive, as lambda-integration, or based on the harmonic approximation and thus only applicable to materials with stable lattices. Thus, a computationally cheap yet highly accurate method with broad applicability is sought after.The objective of this thesis is to e...
Modelling of a Novel Micro Scaled THz Detector
Examensarbete på avancerad nivå, 2009 (Masterarbete)
In order to extend technology into THz part of electromagnetic wave spectrum THz detectors are required. So far THz detectors have been used in astronomical observations with state of the art sensitivity requirements. To achieve the required sensitivity super conducting technology are used (temperatures below 5K). These detectors require the cryogenic tempe...
Collision Rate of Particles Advected in Random Flows
Examensarbete på avancerad nivå, 2007 (Civilingenjör)
Collisions of particles suspended in fluids in macroscopic motion is a subjectwith long history going back to M. v. Smoluchowsky (Zeitschrift f.physik. Chemie, XCII 129-168, (1917)) and P. G. Saffman & J. S. Turner(J. Fluid Mech., 1, 16-30, (1956)).In the case of smooth random flows, the problem can be solved exactly incertain limits, as is demonstrated in t...
