Microscope and it´s use in engineering practice
Kopecký, Jiří ; Dostál, Lukáš (referee) ; Veselka, František (advisor)
This work deals with the use of the light microscope in industry and its use within the automatization of the diagnostic method specialized on electrical machines with a sliding contact. The method is called the dust particles method and it is used to determine the loss of the brushes used in the machines. The current method involves a manual evaluation of an acquired data, which demands additional tests and the evaluation itself is very difficult. The objective of this work is to simplify and accelerate the method using the computer analysis. First, the usage of the light microscope, through which the samples are obtained, is showed. The method uses these samples as the input. Then, the principles of the dust particles method are demonstrated and the image analysis using the MATLAB program follows. The guide to the image analysis with the elimination of rising defects using the MATLAB program is available. Then, the volume of the intercepted dust particles is calculated using the MATLAB program. The dust particles were obtained from the LFC 55h brush using the Arsenal LPT 1513 – T light microscope.

Platform .NET for Numerical Integration
Kopecký, Jiří ; Kunovský, Jiří (referee) ; Šátek, Václav (advisor)
This bachelor thesis deals with numeric solution of ordinary first-order differential equations and their systems. The first part of this thesis contains description of selected one-step integration methods. The second part is devoted to a language intended for differential equation notation. This part at first describes the study of languages of MATLAB, Maple and TKSL/386 simulation systems. Later, based on this study it presents a design of a new language. The penultimate part of the thesis deals with design and implementation of a system intended for the calculation of systems of differential equations. In the final part is then shown usage of this system to solve exercises from the Circuits Theory domain.

Multiplatform Access for Databases Applications
Hromádková, Pavla ; Jaša, Petr (referee) ; Kopecký, Jiří (advisor)
This thesis deals with possibilities of accessing database systems from different devices. It contains analysis, concept and description of the following information system implementation with draft model Model-View-Controller. Concept of the system is made in UML language. The PHP programming language and MySQL relational database server were used during the progression of the system. User interface was implemented by HTML and WML technologies. Final look of the application was achieved by using CSS web technology. Technical report describes multilayer architecture and its advantages in the creation of the information system. It deals with MVC draft model, which is useful in the cases, where´s the need of the separation of the application look, its communication with database and application logic. The work oncemore describes analysis, concept and implementation of multiplatform application for the Drak travel agency. Systém could be currently accessed by handy or web browser. The application is easily extensible for the use in another platform.

Diagnosis sliding contact using practical applications "Methods particulate"
Kopecký, Jiří ; Mach, Martin (referee) ; Veselka, František (advisor)
This thesis deals with the sliding contact of electrical machines and its diagnostic methods. Namely, the dust-particles method for assessing the length decrease of brushes is deeply described. Then, usage of the method in industry is described. The comparison of accuracy between manual version and new automated version of the method using computer analysis is presented. The final section is devoted to the practical verification of the new automated version which was developed especially for large machines. Measurements were performed on a small machine.

Simulation of point processes
KOPECKÝ, Jiří
The aim of the thesis is to create a pack of functions in Wolfram Mathematica software to simulate spatial point patterns of chosen hard-core and Gibbs processes. Then it tries to apply these models to real data, estimate the parameters of models for real data and test the validity of models. The thesis can serve as introduction into the theory of spatial point processes.
