Analysis of Documentation of Real Damage to Vehicles in Road Accidents
Novotný, Václav ; Kovanda,, Jan (referee) ; Vémola, Aleš (advisor)
This diploma thesis deals with a comprehensive analysis of the photographic documentation of vehicle damage in traffic accidents. A systematic overview of the current documentation and included inspection is carried out in the analysis. Police records are compared with records made during the crash tests. Further, the documentation in this thesis is divided into two groups of conflicts. The representative of the accidents are described in detail and then evaluated. Similarly, this procedure is practiced on other car accident that reflect the mutual deformation. The result of this thesis is to determine the optimal location of the lens for the acquisition of documentation and establishing a baseline number of photos to document damage to the vehicle after the traffic accident.

Dynamic Characteristics of Exhaust System and Noise Transmition to the Car Cocpit
Novotný, Václav ; Ramík, Pavel (referee) ; Svída, David (advisor)
This thesis deals with the complex analysis of dynamic characteristics of the exhaust system and the transmission of noise from exhaust system to the vehicle. In the first part is performed modal analysis, which is compared to experimentally measured data. Modal analysis of the complete exhaust system is made with focusing on the influence of temperature of the exhaust system. There is also performed an analysis of noise transmission from exhaust system to the car cockpit.

Termomechanical reliability soldered connections in electronic
Novotný, Václav ; Psota, Boleslav (referee) ; Šandera, Josef (advisor)
The diploma thesis deals with the sphere of solder joints reliability. The narrower focus is use of lead-free solder alloy SAC305 in the production process and parameters of its reliability. The text describes the main factors, which have the influence on the reliability of solder joints under conditions of thermal cycling. These factors also relate with choice of substrates and technological processes of preparation, which are characterized and described. Another part is devoted to estimating the reliability of soldered connections and are listed the fatigue model to estimate reliability. These fatigue models are categorized based on different physical mechanisms that operate in the soldered joints during operation. Based on the comparison of different models is selected the most appropriate model and in conjunction with simulation in ANSYS is estimated reliability. For this purpose is selected soldered connection of the FR-4 substrate and ceramic substrate via SMD component. They are manufactured test kits and subjected to conditions of temperature cycling. Results obtained from experimental measurements are compared with results obtained by simulation and calculation.

Embedded display recognition
Novotný, Václav ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
This master thesis deals with usage of machine learning methods in computer vision for classification of unknown images. The first part contains research of available machine learning methods, their limitations and also their suitability for this task. The second part describes the processes of creating training and testing gallery. In the practical part, the solution for the problem is proposed and later realised and implemented. Proper testing and evaluation of resulting system is conducted.

Creep-fatigue models for solder joints reliability prediction
Novotný, Václav ; Šandera, Josef (referee) ; Švecová, Olga (advisor)
This project is focused on utilization of creep-fatigue models for estimate of reliability lead-free solder joints. It describes basic groups of creep-fatigue models, their usage for estimate of reliability solder joint, advantages and disadvantages. There are discusssed properties of single models, which are on different base. Purpose of this project is find optimal creep-fatigue model for lead-free solder and devise a test structure to which the model will be verified. Results are compared with theoretical calculations.

Czech publications of francophone literature for children and young adults
NOVOTNÝ, Václav
This thesis deals with editions of francophone literary works for children and youth issued during the twentieth century and pursues the publishing policies in this field. It's been written based on a catalogue of works categorised by individual literary styles. Those literary styles and their evolution have served as a ground of the theoretical part of this work. The practical part consists of a catalogue that contains the above mentioned literary works. The annexe includes supplements, in which the data extracted from the catalogue are processed viewed from various perspectives.

The Analysis Of Ceramic Resistor Arrays In Smt
Novotný, Václav ; Vala, Radek
This paper is focused on the area of current electrical manufactory in conjunction with possibilities of computer analysis and monitoring psychical phenomena by computing systems. There are also described processes of preparation and manufactory of testing boards for evaluation of reliability of solder joints on specific microelectronic part which has its place in contemporary electronic production and subsequent analysis of physical processes on these boards under condition of thermal cycling in thermal chamber and their influences on overall reliability of the entire component. For purposes of analysis were chosen SMD resistor arrays in configuration 8x0603 which were soldered on typical substrate FR-4 by SAC305 solder. These soldered resistor arrays are also modeled in Solidworks and analyzed by ANSYS. The results achieved by experimental measurement are complemented by simulations of models.
