PHpix interface board
Opioł, Zbigniew ; Matějka, Tomáš (referee) ; Kubíček, Michal (advisor)
This work investigates the interface and properties of an ionization radiation detector with the PhPix chip, which is the basis of a future large-scale detector for use in nuclear medicine. In the next stage, an IP core for communication between the processor system and the PhPix chips on the Zynq platform is designed. Furthermore, software for video transmission over Ethernet interface is developed.
Radiological, Histochemical and Histological Changes M. Erector Spinae by Patients with a Fracture of Thoracolumbal Spine Treated With Open or Miniivasive Stabilisation
Matějka, Tomáš ; Matějka, Jiří (advisor) ; Džupa, Valér (referee) ; Chaloupka, Richard (referee)
Today, miniinvasive operations are part of modern medicine and in recent years have partially replaced open methods. The aim of this study was to compare radiological, histochemical and histological changes of the erector spinae muscle in patients with thoracolumbar spine fractures treated with open (OPEN) and miniinvasive (MISS) stabilization. The purpose was not to evaluate one method as better or worse, it was only a comparison and finding out the advantages and disadvantages of individual operations. During the study, we compared both the above-mentioned differences in the quality of the erector spinae muscle and laboratory changes in blood levels of muscle enzymes, we compared the duration of operations, the accuracy of insertion of transpediculars screws, blood loss, kyphotization of spine segments and exposure of radiation. It has been hypothesized that muscle damage in all factors will be lower in MISS than in OPEN. A total of 38 patients with type A and B fractures according to the Vaccar classification, 19 underwent MISS surgery and 19 at the OPEN method were included in the prospective randomized study. The average age of the whole group was 46.4 years (18 - 68), the average age for MISS procedures was 42.6 (18 - 66), for OPEN was 48.7 (19 - 68). Only monotrauma of the TL spine was...
Use of 3D printing for the construction of loaded parts
Matějka, Tomáš ; Fojtášek, Jan (referee) ; Zháňal, Lubor (advisor)
This thesis deals with designing and manufacturing of a 3D printed bump stop part of shock absorber with a predetermined deformation characteristic. The aim of this thesis is to confirm or refute the suitability of using 3D printers to produce stressed components. The introduction deals with the approach of the method of additive technology using three-dimensional fixed objects, the method of 3D printing. Followed by a division of individual methods, types of printers and usable materials. The suitability of use for our specific case is also mentioned there. Furthermore, in this thesis, the model itself is designed and the assumed deformation characteristics of the bump stop are calculated using the finite element method. The next part of the thesis describes the production of the bump stop using a 3D printer, the advantages and weaknesses of this technology and evaluated the printed model itself compared to the proposed one. The conclusion of the thesis is devoted to testing the manufactured bump stop, from which follows the suitability of using this technology.
Thermoluminescence measurement system
Matějka, Tomáš ; Král, Jan (referee) ; Kubíček, Michal (advisor)
This thesis deals with revision and design of electronic for measuring system PSI TL 500 which is designed for measurement of thermoluminescence phenomena in photosystem II. Thesis describes principles and properties of the measuring system in its current form and changes for the new version are discussed. Digital control part based on Xilinx Zynq platform is designed. Revision of analog measuring part of system is made and partial changes are implemented.
Analysis of socially responsible activities of the selected company
Matějka, Tomáš ; Musil, Martin (advisor) ; Dvořák, Jiří (referee)
The subject of the thesis "Analysis of socially responsible activities of the selected company" is the analysis of CSR activities, which the company currently performs. The thesis aims to help a company determine whether to actively devote implementation of CSR. And also propose the first steps that the company has implemented in its eventual implementation.
Module for detection of ionizing radiation
Matějka, Tomáš ; Džbánek, Lukáš (referee) ; Kubíček, Michal (advisor)
This thesis deals with design of detector of ionizing X-ray radiation. Conventional PIN photodiodes are used for construction of the detector. The thesis describes issue of using PIN photodiodes for X-ray and gamma radiation detection. Transimpedance amplifier is designed with two diferent modes of detection. Both amplifier variants are compared and their suitability for specific applications is discussed. The thesis describes principle of converting analog signals to digital and describes concept of bus for multiple detectors connection to central unit. Options for paralel data processing are discused in last part of thesis. The detector is implemented and measured values are compared with simulations.
Operating software with web interface for programmable controllers
Matějka, Tomáš ; Kovář, Jiří (referee) ; Houška, Pavel (advisor)
This diploma thesis deals with developing of software, which allows access and control of programmable controllers through web interface. Software uses client server model and for communication between client and server is used Windows Communication Foundation interface which is integrated in Microsoft .NET Framework from version 3.0. Applications were written in C# programming language using .NET Framework libraries. Data visualization in web application was created by Microsoft Silverlight.
Proposal for Effective Multicultural Team Management in an International IT Company
Šimek, Tomáš ; Matějka, Tomáš (referee) ; Konečná, Zdeňka (advisor)
Cílem této diplomové práce je návrh na zlepšení týkající se efektivního řízení multikulturního týmu ve velké mezinárodní společnosti působící v oblasti informačních technologií. V práci jsou uvedeny základní teoretické poznatky týkající se efektivního řízení, firemní kultury, řízení lidských zdrojů a týmové práce. Praktická část je zaměřena na analýzu stávajícího stavu společnosti, díky které bylo možné navrhnout taková opatření, která pří správné implementaci povedou k optimalizaci a zefektivnění samotného řízení týmu, motivace jeho členů, komunikace, výkonnosti a kvality. K analýze současného stavu byly použity rozhovory s jednotlivými členy týmu a dotazníkové šetření.
Comparison of funding for research, development and innovation in the Czech Republic with selected countries.
Matějka, Tomáš ; Peková, Jitka (advisor) ; Matula, Miloš (referee)
This thesis is focused on the analysis of the current system of funding for research, development and innovation in the Czech Republic and the subsequent comparison with foreign countries. The thesis provides a detailed overview of the current funding situation in the Czech Republic, the role of public administration in the process and mentions the critical comments that currently appear most often. Topicality and importance of the topic increases the current proposal on the creation of a new ministry for science. Working on the basis of analysis and comparison with other countries recommends changing the current system of funding for research, development and innovation in the Czech Republic, however, means other than the creation of the proposed new ministry.
Barriers in Communication between Workers in a selected Organization
Matějka, Tomáš ; Hiršová, Miloslava (advisor) ; Míková, Irena (referee)
The bachelor's thesis is divided into two parts: theoretical and practical. This work focuses on communication between managers and their subordinates in the selected organization. In the theoretical part, I explained the basic terms which are necessary for understanding the work. I also described in the theoretical part of several communication barriers that may arise between people in the workplace. In the practical part, I found out a questionnaire selected communication barriers among managers and workers. I then compared the responses of the two groups. The objective of my bachelor's thesis is to identify vertical barrier between superiors and their subordinates. At the end, I tried to propose solutions and thereby improve communication in the selected organization.
