Immersion Tin Surface Finish of PCB
Karzel, Vítězslav ; Zatloukal, Miroslav (referee) ; Starý, Jiří (advisor)
The aim of this work is to study and more deeply understand everything about surface finishing of the printed circuit boards, that are used for lead-free soldering. Mainly we should focus on immersion tin and prepare some fundamental information for future measurement. Therefore, in the first part of the thesis is our main task is to create a~sufficient theoretical background for printed circuit boards, immersion tin and solderability. Then we are able to use previously created theoretical background to measure selected samples. Thereafter the measured data can be used for more strict evaluation, from which the results of measurement can be obtained.

Active database of standart at Institute of design created
Slezák, Jan ; Zimmerman, Martin (referee) ; Dvořáček, Jiří (advisor)
Aim of this bachelor’s thesis is to create compact database of valid standards, which are on hand the Institute of design created with the possibility continuous refilling by database system. A short charakteristics of standard and basic identification data belong to the survey. There is charakteristic of standard, kinds of standards and history of standards in the first part. Creation of standards, their numbering and obligation are introduced in the second part. Databases are introduce in the third part.

Functional Safety for Microcontrollers
Klecker, Jan ; Pavlík, Michal (referee) ; Hejátková, Edita (advisor)
This Master’s thesis deals with the principles and mechanisms of functional safety for microcontrollers. The IEC 60730 and IEC 60335 standards are described, from which the requirements for testing of microcontroller functional blocks are derived. Furthermore, the requirements for designing safety software are discussed. The most important chapter of the theoretical part is the design and discussion of functional safety tests for the given peripherals. In the practical part, a demo hardware of a gas boiler with safety features and diagnostic mechanisms controlled by two NXP KV46 microcontrollers communicating via a UART interface is designed. In the software chapter, the design of the application software for the gas boiler is described and then functional safety tests are implemented for the microcontrollers. For testing and demonstration purposes, a graphical user interface is designed in the FreeMASTER tool.

Legislative Regulations for Vehicle Exterior Noise
Koštuřík, Vojtěch ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
This bachelor´s thesis deals with an overview of legislative regulations for vehicle exterior noise. Introduction is dedicated to acoustics and basic acoustic variables. Next, there are mentioned sources of external noise of vehicles and distribution vehicles by category. The following provides an overview of standards and legislative documents dealing with external noise of motor vehicles. These standards and documents also establish a methodology for measuring external noise, referred to in the following chapter. In the end, there is an assessment of development of legislation in the field of external noise.

Concept for Organizational Culture Change in the SILGOR, a.s. Company
Tošerová, Valérie ; Orlík, Adam (referee) ; Konečná, Zdeňka (advisor)
The aim of this thesis was to summarize the theoretical knowledge related to the concept of organizational culture, describing the most important functions, elements, structures, typology and methods for its analysis. Based on the analysis of organizational culture in the organisation was outlined the current organizational culture through the use of systematic observation and investigation using interviews, written methods of interviewing and document analysis of the organization. Then the deficiencies in the organizational culture of the organization have been detected and the actions and recommendations for improving the current situation towards the desired organizationa culture have been suggested.

Static solution of parking house
Rose, Dominik ; Koláček, Jan (referee) ; Zich, Miloš (advisor)
The bachelor's thesis is focused on the elaboration of a static solution of a parking house with four above-ground floors. Three variants are elaborated, one of which was elaborated in more detail. The proposed elements are the ceiling slab, the columns and staircase. The SCIA Engineer 20.0 program is used to calculate the internal forces. As part of the work, drawing documentation is also prepared. The structure is designed according to correctly valid standards.

Verification Angles
Tesařová, Martina ; Marková, Petra (referee) ; Pernikář, Jiří (advisor)
The main effect of this graduation theses is detailed project for control process of exactness of angular measuring instruments. It is necessary to produce conponents with sufficient accuracy for correct function of machines. That is why there is very important thing to exactly measure proportions of these conponents during industrial process. Then the real parameters of finished products are confronted with measures stated in conponent plans. The final deviations have to fall into fixed limits. Measuring of angles is very important for replacing of machines´ conponents and for economy of producing too...
