Acceleration of numerical computation of heat conduction in solids in inverse tasks
Ondruch, Tomáš ; Komínek, Jan (referee) ; Pohanka, Michal (advisor)
The master's thesis deals with possible ways of accelerating numerical computations, which are present in problems related to heat conduction in solids. The thesis summarizes basic characteristics of heat transfer phenomena with emphasis on heat conduction. Theoretical principles of control volume method are utilized to convert a direct heat conduction problem into a sparse linear system. Relevant fundamentals from the field of inverse heat conduction problems are presented with reference to intensive computations of direct problems of such kind. Numerical methods which are well-suited to find a solution of direct heat conduction problems are described. Remarks on practical implementation of time-efficient computations are made in relation with a two-dimensional heat conduction model. The results are compared and discussed with respect to obtained computational time for several tested methods.

Radar Signals with Pulse Compression Analysis in Matlab
Trnčíková, Veronika ; Dušek, Martin (referee) ; Šebesta, Jiří (advisor)
This thesis is dedicated to pulse modulation influence to the ambiguity function. The ambiguity function indicates the resolution of the system in range and Doppler frequency. The thesis contains the general introduction of radiolocation basis, individual modulations and the solution in MATLAB environment utilizing spare matrix principles. Graphs of ambiguity function for individual modulations created in MATLAB environment are included in the text.
