1. 11. Thermodynamical properties of cellular automata

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Luca Bertolani; [2020]
   Keywords : Thermodynamics; Statistical; Mechanics; Cellular; automata; chaos; complex; matrix; computational; mathematical; 2d; two; dimensional; program; code; python; ising; teaching; ideal; gas; partition; function; equilibrium; non-equilibrium; classification; neighbourhood; local; Physics and Astronomy;

   Abstract : Cellular automata are a set of discrete computational models whose evolution is defined by neighbourhood rules and are used to simulate many complex systems in physics and science. In this work, statistical mechanics and thermodynamics in and out of equilibrium are used to develop a five-class classification scheme for two-dimensional cellular automata. READ MORE

3. 12. Testing the multi-epoch luminosity function of asymptotic giant branch stars in the Small Magellanic Cloud with VISTA

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Róisín O'Rourke Brogan; [2020]
   Keywords : stars: AGB; stars: late-type; stars: atmospheres; stars: variable; small magellanic cloud; magellanic system; stellar populations; model stellar populations; dwarf galaxies;

   Abstract : The physics pertaining to the asymptotic giant branch (AGB) phase of stellar evolution has been studied for many years. However, the mechanics behind many characteristics displayed at this stage are still not fully understood. READ MORE

4. 13. Best practice of extracting magnetocaloric properties in magnetic simulations

   University essay from Uppsala universitet/Materialteori

   Author : Johan Bylin; [2019]
   Keywords : Magnetocaloric effect; Thermodynamics; Statistical mechanics; Monte Carlo simulations; Metropolis algorithm; Wang-Landau method; Isothermal change in entropy; Adiabatic change in temperature; Numerical methods; Effective spin models;

   Abstract : In this thesis, a numerical study of simulating and computing the magnetocaloric properties of magnetic materials is presented. The main objective was to deduce the optimal procedure to obtain the isothermal change in entropy of magnetic systems, by evaluating two different formulas of entropy extraction, one relying on the magnetization of the material and the other on the magnet's heat capacity.

5. 14. Numerical methods for design of the transfer line of the ESSnuSB project : Independent Project in Engineering Physics

   University essay from Uppsala universitet/FREIA

   Author : Karl-Fredrik Boholm Kylesten; [2019]
   Keywords : Accelerator Physics; Physics; Numerical methods; Engineering Physics;

   Abstract : ESS neutrino Super Beam (ESSnuSB) is a project that aim to create ahigh energy beam of neutrinos and anti-neutrinos to study thephenomenon neutrino oscillation and learn more about symmetryviolations in quantum mechanics. To create the neutrino beam, negativeHydrogen ions must be transported from the ESS linear accelerator at2. READ MORE

6. 15. Quality Assessment of Thin Polymer Components using NonDestructive Testing : Degree Project for Master of Science in Mechanical Engineering with emphasis on Applied Mechanics

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Markus Nilsson; Tom Carlén; [2019]
   Keywords : nondestructive testing; polymer; nonlinear acoustics; instant dynamics amplitude recovery.; oförstörande provning; polymer; olinjär akustik; instant dynamics amplitude recovery;

   Abstract : Polymer components are used in many different applications, including in industries where critical applications put high requirements regarding quality assessment. Such applications might include medical or food where the presence of discontinuities might induce bacterial growth or other unpleasantries, thus certain manufacturers must be able to maintain a zero-tolerance towards damaged components.
