Nanoelectrodes for biophysical measurements
Márik, Marian ; Hrdý, Radim (referee) ; Hubálek, Jaromír (advisor)
The aim of the project is formation of nanoelectrodes on the silicon wafer surface by thin-film techniques combined with lithography and nanotechniques developed in LabSensNano. Project is engaged in lithography and in preparation of silicon wafers. Furthermore is proposed a brief proposal of electrodes, proposal of realization and current state of the experiment.

Design and Realization of a System for Masking Dispatcher PC Cut-Off by Backing-Up Data Obtained from TAMRON Weighing-Machine
Štulír, Vojtěch ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
In the productive operation any kind of plant is undesirable due to failure of system that all production has been stopped. Therefore, different security and backup devices that covered those failures are being developed and used. This thesis describes vulnerabilities in the real operation which are important for treatment and reduce the risk of failure in the whole production. Here is analyzed problem dispatching computer failure and its solution using a module for covering failure. The function of module consists in backup during failure, their sending and treating them after system failure removal. Gradually described, there is an analysis of the system and place the module into their architecture. After all details follow description of module development from design through implementation to deployment and testing in reality.

Application for Measurement of Threshold in Quiet and Masking Curves
Bednář, Jan ; Sysel, Petr (referee) ; Schimmel, Jiří (advisor)
Main aim of this thesis is to create an application for measuring threshold in quiet and masking curves in C++ language. First chapter describes basic teory of perceiving sound and phenomenon of masking. Second chapter focuses on description of different hearing measurement methods. Third chapter describes, how the classes and functions for frequency changing oscilator and evaluation were created and how the graph display function works. Next chapter describes, how to use the application properly and how to do the basic calibration, so the data will be displayed correctly. Last chapter shows the correct function, measured thresholds in quiet and masking curves for two subjects.

Testing of room acoustics
Toufarová, Tereza ; Špalek, Karel (referee) ; Sigmund, Milan (advisor)
This paper presents parameters of evaluation of acoustic quality of the space. It is divided into parts presenting physical principle of the origin and movement of the acoustic signal, principles of its processing with current technology and properties of the acoustic field. This is followed by an analysis of the musical part and notes on psychoacoustics. The document contains a description of relevant parameters of acoustic spaces and way in which we can reach desired results, including material analysis. The paper mainly focuses on description of relevant parameters of three acoustic spaces which were measured. The last part of the work is a program for elementary acoustical measurement, which can be provided by means of commonly accessible equipment such as a notebook or a personal computer.
