Study of properties of cementitious composites with fiber reinforcement from inorganic fibers
Gottwaldová, Aneta ; Novosad, Petr (referee) ; Bodnárová, Lenka (advisor)
Diploma thesis deals with study of properties of cementious composites with fiber reinforcement from glass and basalt inorganic fibers. Diploma thesis includes a theoretical and experimental part. The theoretical part deals with information about glass and basalt fibers, their durability and usage. In the experimental part we monitored properfies of cement composites with basalt and glass fibers. Fibers were exposed to an aggressive environment. The properties of composites with reference fibers were compared with composites with fibers affacted by the aggressive environment. The properties of composites were examined after 28 and 90 days. We monitored compresive strenght, bending tensile strenght, tensile strenght, surface layer strenght and SEM.

Influence of input materials for quality architectural concrete
Ondryášová, Veronika ; Novosad, Petr (referee) ; Hela, Rudolf (advisor)
This diploma thesis focuses on the influence of properties of feedstocks for the production of quality surfaces of architectural concrete. The introductory part describes the definition of architectural concrete with the advantages and disadvantages of its implementation. In the following chapters, the characteristics, the dosage or the chemical composition of the input materials are given. Besides the design of the mixture, important parameters for the creation of a quality surface of concrete are compaction, precise placement in formwork and subsequent treatment of the surface. Individual types of architectural concrete, their method of production with the examples belonging to concrete constructions are also given. In the practical part, 4 mixtures were designed, whose type or dosage of feedstocks was changed. In creating mixtures, emphasis was placed on minimal segregation of fresh concrete and the formation of pores on the surface of hardened concrete.

Architectural concrete
Novosad, Petr ; Ďurica,, Tibor (referee) ; Dulenčín, Juraj (referee) ; Klečka,, Tomáš (referee) ; Hela, Rudolf (advisor)
In the development of concrete structures and its finishes we are constantly looking for new ways to highlight the aesthetic value of the concrete. With all the possibilities of shapes, textures and colours, an architectural concrete in the hands of an architect and designer becomes a material, which can be used to express different individual and specific ideas. It is necessary to recognize and cope with these possibilities, but also the limits, which determine the properties of concrete as the proper design and implementation creates excellent finishes that are otherwise inaccessible to other materials and technologies. The theoretical part includes an extensive summary carries out a research on issues of architectural concrete and its production. From this research comes a new definition of architectural concrete and the newly redesigned and determined classes of architectural concrete with respect to the continuous development of technologies and production possibilities, rendering and surfacing. The aim of the thesis is to verify the possibilities of producing quality architectural concrete and additional treatment of the surface with respect to the desired aesthetic quality.

Influence of environmental conditions on the modulus of elasticity of concrete
Peřina, Tomáš ; Novosad, Petr (referee) ; Křížová, Klára (advisor)
Increasingly, the modulus of elasticity of concrete is at the forefront of interest. In the past, it has been neglected to some reason and not taken into due consideration. The theoretical part of the bachelor thesis is to study of factors influencing the static modulus of elasticity in compression. The practical part is focused on monitoring the modulus of elasticity of concrete, based on the different type of the environment stored test specimens. Concrete will be stored outdoor in the water and in the laboratory environment conditions. Designed concrete mixes will be primarily different with the used of type of admixtures but also with type of cement. The result values will be compared on the dependence of environmental conditions of the test specimens.

The use of dynamic non-destructive methods for determining the strength of cement from cement plant Hranice
Procházková, Lenka ; Novosad, Petr (referee) ; Brožovský, Jiří (advisor)
Nondestructive testing methods are employed as a tool for evaluation of parameters of building materials, especially to ascertain strength properties and to determine alteration occured during durability tests. An ultrasonic pulse velocity method is one of the most used nondestructive methods. A resonance method is employed among the nondestructive methods less. The aim of this work is to establish the calibration relationships between parameters of nondestructive testing and compressive strength value and flexural tensile strength value, respectively. Moreover, applicability of the calibration relationships is also discussed.

Wireless Control of Presentations by Pocket Computer
Liška, Jan ; Smrčka, Aleš (referee) ; Novosad, Petr (advisor)
This work deals with design and realization of an application for Pocket PC which controls presentation on notebook or desktop PC. The goal of this project is to free person from staying behind the computer during presentation. With this remote controller this person can move freely in the whole room and can be in better contact with audience. This document consists of short introduction to Pocket PCs and development tools for this devices. The main part describes concept and implementation of this application by client-server architecture. In the end there are suggestions for future development of this application.

Geocaching Support on Pocket PCs with GPS
Kuchta, Michal ; Bidlo, Michal (referee) ; Novosad, Petr (advisor)
Modern technologies of pocket computers (personal digital asistents, PDA) and navigation systems - how to combine them to have a fun? This is the question, that this work tries to answer. In the first few chapters, the work informs reader about the GPS technology, about Geocaching stash hunting game and about technology of pocket computers. A Concept and implementation of WMGeo program, which could be the Geocaching solution for the PocketPC, is presented.

Semiautomatic Book Generator from Web Content
Sysel, Vojtěch ; Novosad, Petr (referee) ; Letko, Zdeněk (advisor)
This bachelor's thesis deals with semiautomatic book generator from web content. The program input is the URL address and a file with a template. From the URL address the program downloads a website from which it finds an interesting part by means of template. This part is then converted into LaTeX. The program output is PDF, DVI or PostSkript file and LaTeX source code which can be used for further modifications of the document. The theoretical part of the thesis deals with description of particular technologies. The practical part describes particular problems with implementation and their solutions. Further, creation of new templates is described there. The last part contains testing and shows using the program on several model examples.

Wireless Control of Desktop Presentation Using Mobile Phone with Bluetooth
Tesař, Miroslav ; Letko, Zdeněk (referee) ; Novosad, Petr (advisor)
The project aims to relieve a person performing a notebook or desktop computer based presentation of a need to control the presentation by a keyboard. The system uses a mobile phone with mobile Java and Bluetooth technology to communicate with the computer. The project focuses on the use by a wide range of mobile phones and it is independent of the presentation program using separate definition of user controls. This document also contains a brief introduction to mobile Java technology and Bluetooth.
