Electrical motors parameters identification using subspace based methods
Jenča, Pavol ; Veselý, Ivo (referee) ; Blaha, Petr (advisor)
The electrical motors parameters identification is solved in this master’s thesis using subspace based methods. Electrical motors are simulated in Matlab/Simulink interactive environment, specifically permanent magnet DC motor and permanent magnet synchronous motor. Identification is developed in Matlab interactive environment. Different types of subspace algorithms are used for the estimation of parameters. Results of subspace parameters estimation are compared with least squares parameters estimation. The thesis describes subspace method, types of subspace algorithms, used electrical motors, nonlinear approach of identification and comparation of parameters identification.

Orthogonal axonometry for secondary schools
Janišová, Lenka ; Moravcová, Vlasta (advisor) ; Surynková, Petra (referee)
This work, which is intended for secondary school pupils and teachers, is fo- cused on orthogonal axonometry for pupils and teachers at secondary schools. The thesis consists of exercises, some of them are stepped in presentations and can be found on the attached CD. Templates of models that students can build themselves are included in the first exercises for better understanding. The text is supplemented by the development of orthogonal axonometry and an analysis of the current state of orthogonal axonometry education in the Czech Republic, based on a questionnaire survey and an analysis of textbooks. The theoretical part of the work was prepared for publication on the website. 1

Secondary school chapters from an orthogonal axonometry
Janišová, Lenka ; Moravcová, Vlasta (advisor) ; Štěpánová, Martina (referee)
Title: Secondary school chapters from an orthogonal axonometry Author: Lenka Janišová Department: Department of Mathematics Education Supervisor: RNDr. Vlasta Moravcová, Department of Mathematics Education Abstract: The work describes the process displaying the situation in orthogonal axonometry from getting distorted the units on the axes through the constructi- ons of elementary objects up to the theoretical solution of objects sections and displaying more complex objects. It includes tasks for practicing. Some of these tasks are available in presentations, which are adapted for projection by a projec- tor and contain step by step solutions of excercise. Auxiliary models are attached to the tasks at the beginning, which consist of the distorted axes problem, so the tasks can be illustratively visualized. The work is intended for secondary school pupils as a material for self-study, presentations and models can also be used for teaching in the school. Keywords: orthogonal axonometry, orthogonal projection, projection, intersection method, construction tasks 1

Tři způsoby interpolace na konečných prvcích
Šolín, Pavel ; Segeth, Karel
Interpolation on finite elements usually occurs in a Hilbert space setting, which means that interpolation techniques involving orthogonal projection are an alternative for the traditional Lagrange nodal interpolation schemes. In addition to the Lagrange interpolation, this paper discusses the global orthogonal projection and the projection-based interpolation. These techniques are compared from the point of view of quality, efficiency, sensitivity to input parameters and other aspects.
