Information System for a Language School
Sikora, Martin ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
The main goal of this thesis is to design and implement an information system for a language school, which will replace the existing data processing in Microsoft Excel tables. The system will work with language school's data like courses, translation, staff, books, customers and makes management work easier. The most of the processes will be accelerated or automated. It will also notify management for upcoming translations' deadlines or employees' ending contracts.

Control of headlight assembly line
Sikora, Martin ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
This thesis deals with design of the reflector assembly line. The document contains the analysis of the customer requirements sheet. In short there is written how to put the parts of the reflector together. The Poka-Yoke method is properly described in this work too. This method is used to design of the actions, which are trying to decrease the risk level of wrong reflector composition as low as it is possible. FMEA and PFMEA methods are explained in theory. There is the plan how to make the analysis too. The instrumentation of one part of the line is designed according to this analysis and according to the customer requirements. The OEE pointer is used to test the right effect of the Poka-Yoke method. The next aim of this thesis is to compare chosen PLCs for control of the assembly line and to choose one of them. On the base of the analysis there is designed the control program in the flowcharts form. One part of this thesis is focused on design of the visualization for the chosen operational panel.

Electro-thermal model and simulation of integrated circuit
Sikora, Martin ; Kledrowetz, Vilém (referee) ; Prokop, Roman (advisor)
Thermal effects in integrated circuits have increasing impact on chip's lifetime and function. For this reason, the chips must be subjected to electro-thermal simulations prior to the launch of production in order to avoid potential circuit failures. Therefore, in the first part of this diploma thesis these effects and methods of creating thermal models are described. The thesis also explores available tools for electro-thermal simulations and the way these simulators work. In the practical part of the thesis, the operation of electro-thermal simulation in the Eldo tool is verified, a method of automated thermal network creation is proposed and a application for its generation based on the circuit layout is implemented. The results of the electro-thermal simulation with the generated thermal network are compared with the results of the currently used method.

Web App for Capturing New Shots of Historical Photographs
Sikora, Martin ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
The aim of this diploma thesis is to design and implement a web application focused on rephotography management. Analyze existing solutions, create list of features and simple graphical user interface. It also includes a design of API structure to communicate with the mobile application. Essential application requirements include adding photos on a map and combining different photos in a photo editor with enhanced auto-alignment features.

Control of pneumatic press model
Sikora, Martin ; Stibor, Karel (referee) ; Štohl, Radek (advisor)
This thesis deals with improving of the pneumatic press model. The document contains short description of press model. It also focuses on completion of safety and functionality of the machine. There are an analyse and an aplication of instruments in the chapter Choice of instrumentation for change of the pressure force and for the increase of safety of this machine. The chapter Construction of the press model selects the mechanical components and solves the aplication for press model. In the section Extension of the control program there are the analyses of the control algorithms and programs for the safety PLC and PLC for vizualization. The last part of this work is devoted to vizualization, which displays the states of the sensors and safety PLC. In vizualization there is the setting of hand-operated mode or the automatic control mode with different pressing force changing in time.

New Integral Formulae in Hypercomplex Analysis
Sikora, Martin ; Souček, Vladimír (advisor) ; Krýsl, Svatopluk (referee) ; Vanžura, Jiří (referee)
Title: New Integral Formulae in Hypercomplex Analysis Author: Mgr. Martin Sikora Department: Mathematical Institute of Charles University Supervisor: prof. RNDr. Vladimír Souček, DrSc., MÚ UK Supervisor's e-mail address: soucek@karlin.mff.cuni.cz Abstract: The Dirac equation for Clifford algebra-valued functions on the even-dimensional Minkowski space can be understood as a hyperbolic sys- tem of partial differential equations. We show how to reconstruct the solution from initial data given on the upper sheet of the hyperboloid. In particular, we derive an integral formula which expresses the value of a function in a chosen point as an integral over a compact cycle given by the intersection of the null cone with the upper sheet of the hyperboloid in the Minkowski space. We also treat the ultra-hyperbolic case where the Dirac equation gives the ultra-hyperbolic system of partial differential equations. An analogue of the second order Cauchy formula is proved for (n − 1)-vector-valued holo- morphic functions. It reconstructs values inside a bounded domain in the 2n-dimensional complex space by integrating over the characteristic boun- dary of the domain. 1
