Deploying thin clients and terminal servers in various environments that differ in requirements for load and performance
Králík, Martin ; Lattenberg, Ivo (referee) ; Kouřil, Jiří (advisor)
The thesis deals with possibilities of the use of terminal servers and available virtualization technologies on Microsoft, Vmware and Citrix platforms.In the first part, technical principles for virtualization are analyzed in detail and contributions to individual technologies are compared.The second part is practically aimed and deals with the suggestion of testing methodology.The testing methodology consists of identification of key factors describing user´s behaviour, which are subsequently used for selection and dimensioning of hardware architecture.The testing methodology is transformed into a scripting language and prepared for automated tests.The realized tests can be divided into groups dealing with sever load performance, monitoring data transfer, and mapping of the system time response to user´s stimulation.Thin and software clients are computed on the clients side.Performance characterizations of RDP and PcoIP protocols are monitored and compared here. On the basis of the results of performed tests two case studies for computing thin clients in the environment of The Department of Telecommunications,Brno university of Technology and in a basic school are elaborated. The first case study intended for The Department of Telecommunications is concerned with computing of VMware View technology for 150 clients. The second one supposes to compute Microsoft Remote Desktop Services in the system enviroment of a basic school for 15 clients.

Classification of sleep phases using polysomnographic data
Králík, Martin ; Kozumplík, Jiří (referee) ; Ronzhina, Marina (advisor)
Aim of this thesis is the classification of polysomnographic data. The first part of the thesis is a review of mentioned topic and also the statistical analysis of classification features calculated from real EEG, EOG and EMG for evaluating of the features suitability for sleep stages scoring. The second part is focused on the automatic classification of the data using artificial neural networks. All the results are presented and discussed.

Metodika zajištění bezpečnosti historických vodních děl při povodních
Brouček, Miroslav ; Fošumpaur, Pavel ; Králík, Martin ; Satrapa, Ladislav ; Zukal, Milan
Metodika slouží pro zdokonalení stávajících postupů při zvyšování bezpečnosti historických vodních děl při povodních metodami hydraulického modelování na fyzikálních modelech. Metodika reaguje na aktuální potřebu zvyšování kapacit funkčních objektů vodních děl dle významně zvýšených bezpečnostních požadavků dle platné legislativy. Metodika je obecně platná také pro případy vodních děl, která nemají statut kulturních památek. V případě historických vodních děl je třeba přistupovat k jejich rekonstrukcím citlivě z důvodu zachování jejich kulturně historického charakteru. Metody hydraulického výzkumu umožňují nejspolehlivější modelovací nástroj pro ověřování stávajících kapacit funkčních objektů a optimalizaci navržených rekonstrukcí s minimálními dopady na charakter památkově chráněných staveb.

PSG-Based Classification of Sleep Phases
Králík, M.
This work is focused on classification of sleep phases using artificial neural network. The unconventional approach was used for calculation of classification features using polysomnographic data (PSG) of real patients. This approach allows to increase the time resolution of the analysis and, thus, to achieve more accurate results of classification.

Vylepšení procesu digitální podpory použitím osvědčených postupů přístupem ITIL, Kanban a TOC v multikulturním prostředí
Králik, Miroslav ; Bruckner, Tomáš (advisor) ; Kalantar Hormozi, Kaveh (referee)
Many companies today have to deal with business processes optimization, ongoing removal of system obstacles and identifying any bottlenecks laying on the way which are preventing us to reach our goals. I would like to show how we have dealt with similar problems in our case applied in the department of web application maintenance. In the first chapter I will introduce the basic information about the history, environment the company operate in and maintenance activities which are part of the process. Following with description all of the system obstacles and bottlenecks identified in the process and possible solutions or improvements for their elimination. In the last chapter I will present the achieved results after my executing of the proposed improvements and if the expectations have been met or not and what positive or negative influence it has brought.

The neutron flux characterization on the microtron MT25
Chvátil, David ; Králik, M. ; Granja, C. ; Krist, Pavel
Microtron is a small cyclic electron accelerator. When it is used as a source of neutrons, electrons must be converted to neutrons by means of nuclear reactions. Spectra of neutrons produced by high energy X-ray photons in lead and uranium targets installed on the microtron MT25 were measured by the Bonner sphere spectrometer with passive detectors of thermal neutrons. Neutron yield from uranium target was nearly two times higher than from the lead one.

Maven repository management
Králik, Miroslav ; Pavlíček, Luboš (advisor) ; Pecinovský, Rudolf (referee)
In this thesis I would like to describe a tool used for build and categorize projects in Java language for commercial or non-commercial use. The first part is concerned with the tool called Maven that is used either for desktop projects or web projects. The aim is to present the purpose, operation principle and the role which represents the whole life cycle of the project compilation. This includes a description of its advantages and disadvantages of use and in case of use, model his communications with the remote Maven repository manager implemented with and without a repository manager. The second part is dedicated to the description of the most famous Maven repository managers, namely the Apache Archive, Sonatype Nexus and JFrog Artifactory, indicating their functionality. These managers I will try to compare with each other, indicating their advantages and disadvantages with regard to technology solutions to the most important functions. The last part, which can handle a detailed description of the installation and basic configuration of Sonatype Nexus application and also I will try to find solutions to difficult situations in the migrated data and existing users of Apache Archive.

Study of Unique Bracelets from Early Bronze Age
Vykouková, J. ; Březinová, Helena ; Fikrle, Marek ; Frána, Jaroslav ; Králík, M. ; Lutovský, M. ; Samohýlová, A. ; Smejtek, L.
This paper aims to assess two unique bracelets from several points of view, including the history of their discovery, their typological and chronological classification, and analysis of the material from which they were made - above all, analysis of the corrosion layers and surviving textile and human skin imprints, as well as questions of conservation.
