  2. 1. Numerical Methods for Wave Propagation : Analysis and Applications in Quantum Dynamics

    Author : Emil Kieri; Sverker Holmgren; Vasile Gradinaru; Hans O. Karlsson; Tobias Jahnke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computational wave propagation; quantum dynamics; time-dependent Schrödinger equation; spectral methods; Gaussian beams; splitting methods; low-rank approximation; Scientific Computing; Beräkningsvetenskap;

    Abstract : We study numerical methods for time-dependent partial differential equations describing wave propagation, primarily applied to problems in quantum dynamics governed by the time-dependent Schrödinger equation (TDSE). We consider both methods for spatial approximation and for time stepping. READ MORE

  4. 2. Chemistry: content, context and choices : towards students' higher order problem solving in upper secondary school

    Author : Karolina Broman; Eva Silfver; Dan Johnels; Judith Bennett; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; chemistry education; upper secondary students; meaningful learning; higher order thinking; problem solving; context-based learning; interest; educational choice; identity; kemididaktik; didactics of chemistry;

    Abstract : Chemistry is often claimed to be difficult, irrelevant, and uninteresting to school students. Even students who enjoy doing science often have problems seeing themselves as being scientists. This thesis explores and challenges the negative perception of chemistry by investigating upper secondary students’ views on the subject. READ MORE

  5. 3. Solving the correspondence problem in analytical chemistry : Automated methods for alignment and quantification of multiple signals

    Author : Erik Alm; Magnus Åberg; Beata Walczak; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Abstract : When applying statistical data analysis techniques to analytical chemical data, all variables must have correspondence over the samples dimension in order for the analysis to generate meaningful results. Peak shifts in NMR and chromatography destroys that correspondence and creates data matrices that have to be aligned before analysis. READ MORE

  6. 4. Feasible Direction Methods for Constrained Nonlinear Optimization : Suggestions for Improvements

    Author : Maria Mitradjieva-Daneva; Maud Göthe-Lundgren; Torbjörn Larsson; Clas Rydergren; Anders Forsgren; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; constrained nonlinear optimization; feasible direction methods; conjugate directions; traffic equilibrium problem; sequential linear programming algorithm; stochastic transportation problem; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : This thesis concerns the development of novel feasible direction type algorithms for constrained nonlinear optimization. The new algorithms are based upon enhancements of the search direction determination and the line search steps. READ MORE

  7. 5. Constructing Algorithms for Constraint Satisfaction and Related Problems : Methods and Applications

    Author : Ola Angelsmark; Peter Jonsson; Brahim Hnich; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; constraint satisfaction; CSP; graph problems; algorithm construction; computational complexity; microstructures; graph colouring; decision problems; optimisation problems; quantum computing; molecular computing; Computer science; Datavetenskap;

    Abstract : In this thesis, we will discuss the construction of algorithms for solving Constraint Satisfaction Problems (CSPs), and describe two new ways of approaching them. Both approaches are based on the idea that it is sometimes faster to solve a large number of restricted problems than a single, large, problem. READ MORE
