Audio matrix-switch
Dluhý, Vojtěch ; Kaller, Ondřej (referee) ; Šebesta, Jiří (advisor)
Target of this bachelor thesis is make analyse and concept of matrix for switching audio signals with best quality in radio station. Inputs are regulated and outputs are adjusted to line level for connecting with another devices. Matrix is controlled from PC over USB by microcontroller. From this findings is made electrical scheme, PCB a mechanic design of this equipment. Finally, device is constructed.

Industrial state indicator
Růžička, Zdenek ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Diploma work deals with industrial display systems, indicators and their proposal. These systems are used everywhere that is necessary to mediate transmission of information. Own proposal of indicator is very specific and depends on given application and used display. In practice there is possible to use a few types of displays but in this diploma work there are used only sedmisegmental and matrix. Common component of proposal is microcontroller. No less significat and important part of the proposal is a choice of interface and communication protocol. The correct choice of hardware that is completed with software we will obtain complete status indicator.

Looking for an optimal aiming point in playing darts
Mareček, Petr ; Rajmic, Pavel (referee) ; Mangová, Marie (advisor)
The thesis deals with recommendation optimal point of dartboard. The first part is theoretical, where is described issue of probability, distribution of variation and significant distribution of variation. At the end of theoretical part is described the Fourier transfrom. The second part of the thesis deals with the design and implementation of web application. The design and implemention of web application uses the theoretical part for assigment optimal point of dartboard.

Sizing of the waves geometrical parameters fabricated on the sheet metal die
Stupárek, Daniel ; Forejt, Milan (referee) ; Samek, Radko (advisor)
This thesis approaches the problem of the return of the original geometric shape of the wave which is created on die panels. Die is used as a structural feature of the fiber-cement roofing material in its shipment in the production line. Based on the study of the theory of cold formed sheet metal determine the actual status in the plant. The method of calibration was designed from the collected informations about the original manufacturer of sheet metal panels. Under this proposal and calculation of the required forming power for the recalibration wave in the factory device for the die calibration was designed and constructed. Equipment calibration was performed on two types of corrugated panels and the result fulfilled the theoretical assumptions. In conclusion is processed technological-economic evaluation and the accompanying drawings.

LOGISTIC CONCEPT FOR VIRTUAL ORGANISATIONS
Kuřitka, Ivo ; Jurová, Marie (advisor)
The thesis addresses the role of logistic concept in a virtual organization. Theory of virtual organization was complemented by a definition of virtuality and a model of virtual organization was created. Two measurable properties of virtual organizations are used for construction of a 2x2 matrix of centralization – integration giving thus clear view of virtual organizations taxonomy. Duality of hierarchic dimension of network structure and layers of the virtual dimension led to a comprehensive description of virtual enterprises with the aid of newly created 3x3 matrix of virtual layer – hierarchy level. Within this framework are interpreted processes in virtual organization during virtual enterprise’s lifecycle. Dynamic restructuring and stability issues are explained with the aid of the matrixes. A consistent approach of presented virtual organization’s theory gives interpretation of emerging logistic concept. The use and application potential of presented theory is exemplified in development of RFID implementation method for virtual organizations. Attention is paid to RFID costs and benefits analysis under condition of virtual organizing.

Electrical motors parameters identification using subspace based methods
Jenča, Pavol ; Veselý, Ivo (referee) ; Blaha, Petr (advisor)
The electrical motors parameters identification is solved in this master’s thesis using subspace based methods. Electrical motors are simulated in Matlab/Simulink interactive environment, specifically permanent magnet DC motor and permanent magnet synchronous motor. Identification is developed in Matlab interactive environment. Different types of subspace algorithms are used for the estimation of parameters. Results of subspace parameters estimation are compared with least squares parameters estimation. The thesis describes subspace method, types of subspace algorithms, used electrical motors, nonlinear approach of identification and comparation of parameters identification.

Cutting forces when drilling fibre reinforced composites
Režný, Tomáš ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
This master´s thesis is focused on fibre–filled composite materials, their distribution, labeling, usage, development and production. The aim of this work is complex processing of acquired technical knowledge, and evaluation of technological rehearsals of drilling composite materials which are reinforced by glas fiber and prepreg in terms of the impact of the machined material, wor-king conditions and the tool, and its wear to the feed force value and torque.

Clouds and Hills Generation Using Fractal Geometry
Tůma, Petr ; Zuzaňák, Jiří (referee) ; Venera, Jiří (advisor)
This work is concerned with generation of landscape objects using fractal geometry. In this work is explained what the fractal is and terms associated with them. The other parts describe basic theoretical ideas and implementation of these algorithms. The Capital theme is generation of models clouds and hills in values of input parameters, their presentation and date media saved there. The project includes my algorithm extension for hills generation of course. At the conclusion of this work are summarized tendencies of next development and my results.
