Car black boxes /the problem of data acquisition and analysis for use in forensic science/
Lenková, Alžběta ; Schmidt, Drahomír
The amount of recording devices for independent installation to cars and trucks is increasing. These devices can be called cars’ black boxes. They measure the fundamental vehicle dynamics and record the actual GPS position of the car; alternatively they are able to record the video sequence. The usage of these devices for the vehicle accident analysis is undoubtedly advantageous. This article is aimed to the problematic of analysis of data acquired from these systems, definition of sources of uncertainties and errors. The aim of this article isn’t in the certain evaluation of any system. The aim is to give an impulse for the expert discussion in the field of demands and requirements to these independent systems from the forensic expertise point of view. A comparison with the EDR units is outlined.

Risk Management of a Company Using Data Analysis Tools
Halamová, Kateřina ; Sádlík, Libor (referee) ; Kříž, Jiří (advisor)
This diploma thesis focuses on risk management of a selected company using data analysis tools. The thesis comprehends three main parts. The first part aims at an introduction and presentation of a selected company, and marketing analysis of its surroundings is realized. The second part addresses theoretical issues concerning risk management and data analysis tools. In the third part, financial analysis and evaluation of the possible risks of the company using data analysis tools are realized. Eventually, for the highest risks precautions are proposed.

Analysis of operation data for purposes of optimization
Slavíček, Martin ; Pavlas, Martin (referee) ; Touš, Michal (advisor)
This thesis deals with analysis of operation data for purposes of optimization. The thesis is divided into four chapters. First chapter focuses on present and future development in waste management legislation. It mainly deals with prevention, recycling and disposal of waste. Second chapter more closely describes waste-to-energy process. This chapter also describes the technology of municipal waste incinerator in Liberec, Termizo, a.s. Third chapter starts with description of tools used in design of the models based on operation data. Then the models for individual technological nodes are described. The last part is focused on building a complex model of Termizo using previous results.

Optimisation of gear ratio for racing cars
Bém, Pavel ; Roupec, Jakub (referee) ; Mazůrek, Ivan (advisor)
Pavel BÉM Optimisation of Gear Ratio for Race Cars DW, IAE, 2008, pp. 62, fig. 69. At first I labellig problems about gearboxes than, I review dataloggers for racing cars using now. I create model of dynamic simulating car move during at akcelerating and decelerating on choice track. I create program analyzating data from telemetry and applicated dynamic model to optimisation gears ratio.

Data analysis from moving vehicle
Kvapil, Josef ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
The thesis deals with data analysis obtained from the traffic simulator. The data are from trajectory of vehicle movement. The analysis are suggested to driving trajectory which are obtained from the characteristic parameters for the subsequent detection of the critical vehicle position. Analysis and evaluation of the detection critical vehicle position are solved in the Matlab program scripts.

Data Mining
Slezák, Milan ; Hynčica, Ondřej (referee) ; Honzík, Petr (advisor)
The thesis is focused on an introduction of data mining. Data mining is focused on finding of a hidden data correlation. Interest in this area is dated back to the 60th the 20th century. Data analysis was first used in marketing. However, later it expanded to more areas, and some of its options are still unused. One of methodologies is useful used for creating of this process. Methodology offers a concise guide on how you can create a data mining procedure. The data mining analysis contains a wide range of algorithms for data modification. The interest in data mining causes that number of data mining software is increasing. This thesis contains overviews some of this programs, some examples and assessment.

Least-squares fitting of multivariate data
Hrabec, Pavel ; Bednář, Josef (referee) ; Tomášek, Petr (advisor)
Thesis sumarizes basic theory required for inference of aproximation using the least squares method and aplicates this method on data obtained from engineering practice. Within thesis were created programs, in MATLAB enviroment, to solve this problem. MATLAB already contains several algorithms, wich are useful for solving this problem. Thesis includes comparsion of properties and test of those algorithms.

Use of Benford's Law in election results analysis
Pikhart, Miroslav ; Holý, Vladimír (advisor) ; Zouhar, Jan (referee)
The topic of the thesis is introduction to Benford's law and its usage in forensic data analysis. First part of the thesis covers the theoretic basics and explains how conformity is tested. All introduced tests are then applied in second part, which works with two independent datasets. Russian presidental elections 2012, where several scientific articles discuss whether there was foul play involved or not. In comparsion, the second dataset contains czech presidental elections 2013, where no suspicions were ever raised. Both datasets are analyzed using the R software and it is shown that while the czech data indeed conforms to Benford's law, the russian data shows no conformity whatsoever. Also a mistake in one of the R packages used is found and an update is suggested.
