Effect of a bicycle's component on the energy expenditure
Růžek, Ondřej ; Jindra, Matouš (advisor) ; Baláš, Jiří (referee)
Title: Effect of a bicycle's component on the energy expenditure Objectives: Aim of this bachelor's thesis is to determine the difference of energy expenditure in a different component mounting frame of the bicycle. Methods: The study involved 6 probands aged 25.5 ± 3.6 years. Energy expenditure was calculated on the basis of oxygen consumed (O2) and carbon dioxide exhaled (VCO2). To measure was used exhaled gas analyzer Metamax from Cortex and method spiroergometry. Probands completed two runs cadence of 95 rounds per minute on a bicycle with a different component (a shock). Completed line measured 750 meters, led to a gradient of 5 ř ± 2 řand lasts 3 minutes. Results: In our study we found that the differences in energy intensity during bicycling on a hard-tail bike compared to a full-suspension are due to the standard error of the analyzer exhaled gases Metamax® insignificant. VO2 values during the study period did not exceed the threshold of 2 ml /kg/min for the confirmation the authenticity of our hypothesis. Cycling with two shock-absorbers at a distance of 750 m long and 3 minutes remains segment with the inclination of 5 ř ± 2 ř cause energy expenditure in the average value of 161.23 ± 33.15 kJ versus bicycling without shock-absorber and 160.98 ± 24.10 kJ expenditure, which represents an...

IDE-supported development of component-based applications
Hermann, Lukáš
Unlike many proprietary component systems, the academic ones do not have sufficient support in integrated development environments. This the- sis analyzes development of component-based applications in terms of the SOFA 2 component system and it finds out that the main issue is an in- sufficient connection between processes of common application design and creation of particular components. Based on this analysis, it defines a subset of the UML, a universal language for application design, and its semantics regarding entities of the SOFA 2 component system. Furthermore, it creates a tool integrated to the Eclipse IDE, which enables a developer to automat- ically generate these entities from a UML component model as well as to connect this model with already existing entities enabling their automatic correction in case of model changing. This tool is designed modularly so that it is possible to easily change semantics of the model or using it for other models. Finally, this thesis analyzes possibilities of extensions of this tool for other component systems, code generation and component behaviour verification.

C-language code generator for SOFA 2
Ježek, Lukáš ; Bureš, Tomáš (advisor) ; Bulej, Lubomír (referee)
SOFA 2 is a component system employing hierarchically composed components. It provides ADL-based design, behavior specification using behavior protocols, dynamic reconfiguration of the components, and modeling of the component communication by software connectors. This allows seamless and transparent distribution of component applications. The connectors can be automatically generated, SOFA 2 contains Java connector generator allowing to connect components with Java interfaces. The aim of this thesis is to implement C code generator and integrate it into the current SOFA 2 connector generator framework, so that C connectors can be automatically generated and thus components written in C language can be transparently connected in distributed environment. The proposed C code generator is based on the concept of template transformation, where templates containing mixture of C code and a scripting Domain Specific Language are transformed to a pure C code. Strategic term rewriting method provided by Stratego/XT framework is used for evaluation of the scripts within the templates.

Mode Change in Real-time Component Systems
Outlý, Matěj ; Bureš, Tomáš (advisor) ; Malohlava, Michal (referee)
The goal of the thesis is to examine possibilities of dynamic reconfiguration in real-time component systems, especially to formally describe support of operating modes. The thesis introduces a reconfiguration mechanism based on properties and relations between them. The mechanism is designed to facilitate a straight forward modeling of operating modes and reconfiguration rules and preserves re-usability of assembled components. The thesis also presents a realization of the mechanism suitable for the domain of embedded real-time systems.

Dynamic reconfiguration in SOFA 2 component system
Babka, David ; Bureš, Tomáš (advisor) ; Pop, Tomáš (referee)
SOFA 2 is a component system employing hierarchically composed components in distributed environment. It contains concepts, which allow for specifying dynamic reconfigurations of component architectures at runtime, which is essential for virtually any real-life application. The dynamic reconfigurations comprise creating/disposing components and creating/disposing connections between components. In contrast to majority of component systems, SOFA 2 is able to specify possible architectural reconfigurations in the application architecture at design time. This allows SOFA 2 runtime to follow the dynamic behavior of the application and reflect the behavior in architectural reconfigurations. The goal of this thesis is to reify these concepts of dynamic reconfigurations in the implementation of SOFA 2 and demonstrate their usage on a demo application.

Connection of elektrothermal devices to the network
Sumka, Martin ; Lázničková, Ilona (advisor)
This thesis devotes with electrothermal devices and their behavior when connected to the network. It describes the basic types of electrothermal equipment, their structure, construction, principle of converting electrical energy into heat energy and goings that occur during their operation. It also examines the basic types and ways of dealing with compensation and symmetrization applied on different types of electrothermal equipment. It explains the basic methodology used for design of compensation and symmetrization of particular electrothermal equipment and components.

Information System with Interpreter for Measured Data Processing and Visualisation
Šifra, Martin ; Skála, František (referee) ; Szőke, Igor (advisor)
This thesis describes the design and implementation of web-based information system for performance tests of Czech Mountaineering Association's sport climbers management. The system is implemented in PHP using frameworks Nette and Doctrine 2 with an emphasis on easy extensibility and maintainability. Beside basic operations allows integrated interpreter to execute extensive calculations with the data. Build solution keeps features of the spreadsheet and makes data available from the Internet. Its usage accelerates orientation in data with posibility of their visualization in order to improve the training of athletes.

System of AJAX Component for Framework Yii
Mahr, Martin ; Dytrych, Jaroslav (referee) ; Máčel, Lukáš (advisor)
The bachelor thesis deals with the web technologies PHP, HTML, JavaScript, AJAX, jQuery library and Yii framework. Outcome of this work is to evaluate these technologies and the development of an extension module for jQuery library and Yii framework. These extensions together provide the environment for the development of user interface components that are able to communicate with each other via AJAX technology and allows to create dynamic Web pages.
