Analysis of the influence of thermal effects on thermophotovoltaic system
Kolář, Jakub ; Vyroubal, Petr (referee) ; Šimonová, Lucie (advisor)
This semestral thesis focuses on the description of specific renewable resources in the form of thermophotovoltaic cells using selective radiators with micro/nano structures. This work deals with an introduction of renewable resources and specifically focuses on thermophotovoltaic. Thesis describes basic principles, but also influences affecting the proper functioning of these systems. It also focuses on selective radiators, which are created by mikro/nano structures, and factors that can affect their implementation or simulation. Part of the work are also examples of calculations of basic parameters of the structures, which will be used in the simulations. Next chapters are dealing with simulations which are analyzing thermal effects on termophotovoltaic system. Except the analysis itself there is also partial optimalization solving some of the negative thermal effects.

The security of operating systems for mobile devices
Kolář, Jakub ; Babnič, Patrik (referee) ; Rosenberg, Martin (advisor)
This term paper explains the concepts related to security of mobile devices. The first chapter acquainted with how to develop mobile operating systems and what types are found on the market today. Then the work explains the basic types of attacks and security vulnerabilities. Further work is discussed in the most famous and most popular operating systems, from their basic descriptions, architecture, and then security. In the eighth chapter of this work is a basic description and explanation of the function code itself created by malicious applications. The chapter contains weaknesses of the Android operating system used by the application, opportunities spread of malware and protect against possible attack. In the last chapter is contained laboratory task that acquaints students with the Android operating system and focuses on knowledge inappropriately protocols used to communicate with the Internet applications.

Boilers for house heating
Kolář, Jakub ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor thesis is focused on topic cover liquid fueled boilers with power up to 200 kW used for the heating family house and block of flats. Distribution and characteristics of liquid fuels, formation and processing of oil as raw material in liquid fuel production is reviewed in the introduction. First part of this thesis is mainly focused on heat oils. Boilers applicable to house heating, theirs energetic score and specificity and types of liquid fueled boilers are reviewed in second part. In the last part of this thesis is maked a calculation and shows comparative economical computation of convenient types of boiler application.

Design of replicated production of the selected part using the technology Reverse Engineering and Rapid prototyping
Kolář, Jakub ; Jaroš, Aleš (referee) ; Slaný, Martin (advisor)
This study has been as a diploma project at BUT. Theoretical part describes the most used methods in Reverse engineering and Rapid Prototyping. Each method describes its characteristics, usability and pros and cons in general. Practical part of this study deals with application of these methods. Goal of this work has been to obtain a digital model of a winker from Škoda 1000 car using optical scanner ATOS, making a new master model in CATIA software, analyzing its dimensions compared to the scanned model and choosing a suitable manufacturing technology with emphasis on functional properties of this component.

Demografická analýza ORP Moravská Třebová
Kolář, Jakub
This bachelor thesis deals with the analysis of demographic development of the municipality with extended competence Moravská Třebová form 2001 to 2014. The analysis follows the development of demographic indicators such as population, mortality, birth rate, marriage rate, divorce rate and migration. The prognosis of development for next years is used for selected indicators using time series methods of compensation appropriate trend function.
