Improving energy parameters of single-phase induction motors
Dospěl, Leoš ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
Bachelor thesis Improving energy parameters of single-phase induction motors deals with issues of lowering the losses of a small single-phase induction motor J22VV506 from ATAS Elektromotory Náchod a.s.. The first part deals with the theory of asynchronous motors and the issue of losses and their reduction is described in this part as well. In the second part engine parameters are measured and calculated efficiency of the machine and suggested ways to reduce losses. In the last part is measuring motor with the proposed regulation.

Calculation of induction machine cooling
Záruba, Jan ; Huzlík, Rostislav (referee) ; Janda, Marcel (advisor)
This thesis discusses in the first part of the theoretical concept of flow and cooling induction machine. His behavior , characteristics and possible variants of its calculation . Questions concerning losses from the engine, through the second cooling flow types and finally the calculation. The second part focuses on practical laboratory measurements on a real model. Furthermore, the evaluation of its results. The third part focuses on computer simulation and calculation. The third part is further divided into three phases , where in the first phase devoted to the calculation and simulation flow to the fan motor. In the second stage, the third part deals with the flow in the engine itself , and the third is described and simulated temperature analysis . In the final third phase are subsequently evaluated by computer simulations and compared with practical measurements . This comparison is based on the theory described from the beginning.

Analysis of intracranial pressure
Procházka, Ondřej ; Kolářová, Jana (referee) ; Kozumplík, Jiří (advisor)
The aim of my bachelor’s work is the literature review about problematic of measurement and evaluation of intracranial pressure. I describe physical principle of intracranial pressure, anatomy of cerebral ventricle and different accesses and placement of measuring instruments in intracranial place. Moreover I describe evaluation of clinical data at standard way and explain analysis in frequency and time domain by program MATLAB. I make a script for analysis ICP data. It calculates main ICP, amplitude and latency of waves, RAP index and shows spectrum of amplitude.

Data resources analysis of third parties in the Internet environment
Paulech, Michal ; Krajsa, Ondřej (referee) ; Koutný, Martin (advisor)
This bachelor’s thesis is about planning and making of system, which working with thirdparty data sources, mainly Facebook API, Twitter API and Expedia API. This system is monitoring profiles on social networks, their data and content. The system allows monitoring the success of individual profiles on social networks. The system consists of several modules and in the future the system could be extended to include other functionality.

Design system for the detection and quantification of requirements to the control system of intelligent house
Kotík, Miloslav ; Novotný, Jan (referee) ; Bátora, Branislav (advisor)
Bachelor thesis focuses on analysis of the investor's requirements for control system of intelligent house. It is designed questionnaire to guide the designer in communication with the investor and this process is converted into an interactive form as a schedule. On the basis of the questionnaire is designed a procedure for automatic evaluation and transfer of detected investor’s requirements into the list of recommended components of a Tecomat Foxtrot control system and its peripherals for implementation. The first two chapters are theoretical and describe the intelligent house and the Tecomat Foxtrot control system. The last chapter of bachelor thesis describes the Design system itself and its parts - questionnaire, database, form, program evaluation.

Correlation dimension analysis for heart rate variability analysis
Ptáček, Ondřej ; Čmiel, Vratislav (referee) ; Janoušek, Oto (advisor)
Bachelor thesis deals with the analysis of heart rate variability (HRV). By focusing on the analysis of HRV in the time domain and mainly using correlation dimension. It is necessary to propose a methodology for evaluating changes in HRV data using these two techniques of analysis and the comparison of the two approaches. Subsequently create an application in MATLAB for analysis of HRV, which is able to evaluate the effect of changes in HRV caused by ischemia. In the last section it is necessary to discuss the results and the comparison of the two approaches to detect changes induced by ischemia.

Mathematical modelling of HTTP network traffic
Miklica, Jan ; Vajsar, Pavel (referee) ; Molnár, Karol (advisor)
The aim of this thesis is to capture network tradic on the HTTP protocol. Then from the captured tradic to analyze parameters using selected models and compare them with the achal properties of real network traffic. This bachelor´s thesis describes the HTTP protokol and mathematical modeling, and simulation models developed for it. The document described the capture of data tradic on HTTP using Wireshark. In the next part are performed elemental analysis of selected models. In conclusion the analysis results of the selected models are described.
