Comparison and Transformations of Pathway Databases
Němeček, Pavel ; Šilhavá, Jana (referee) ; Smrž, Pavel (advisor)
The main topic of this work are comparison and transformations of pathway databases. Large part is dedicated to databases KEGG and BioCarta. In work are described formats of provided data. In process of searching for overlapping pathways between databases are used clustering, edit distance, NCBI gene numbers and equivalent relationships comparison. The system was written in C++ and using XML parser. Results are text outputs, eventually files in DOT language, which can be executed with GraphViz to generate graphs.

3D Volume Rendering Data Visualization
Němeček, Pavel ; Kubíček, Radek (referee) ; Kršek, Přemysl (advisor)
The first part of this project is focused on theoretical analysis of methods for rendering volume data. Both methods are analyzed showing the volume data using triangle mesh, and methods for direct volume rendering. Ray Casting is presented in detail. Possible way of its realization using graphics card is the subject of implementation part. The paper presents several methods that could be applied to ray casting and achieve different results of visualization of the same data. The work also aims to create a graphical user interface that allows interactive visualizations.

Evaluation System of Thermal Condition Environment and his Measurement Uncertainties Analyze
Košíková, Jana ; Němeček, Pavel (referee) ; Kureková, Eva (referee) ; Vdoleček, František (advisor)
The Ph.D. thesis deals with the evaluation of indoor thermal environment in which people are located. A great attention is paid to the thermal comfort. If a person in a given environment does not feel well, then makes mistakes. Thermal comfort is created many parameters that can be monitored and managed. These parameters include not only temperature but also other parameters such as the mean radiant temperature, operative temperature, humidity and air velocity and the draft. All these parameters can be measured. The standard ČSN EN ISO 7726 is written how and what the parameters are measured. Furthermore, this standard provides requirements for measuring equipment. There are many professional measuring devices. Unfortunately, these devices are very expensive. Therefore are within the project GACR 101/09/H050 - Research on energy- saving equipment to achieve the quality of the indoor environment at our faculty developed sensors for thermal comfort, which have showed comparable accuracy measurements as a professional , but it will be cheaper than professional. Knowledge of real parameters of the developed sensor thermal comfort environment is important, as with any other measurement devices, and also need to verified whether it has the required accuracy. In order to objectively sensors testing were developed two chambers - the testing and calibration chamber. The developed sensors were tested both in the open laboratory, and also in the test chamber. Then uncertainties measurement were calculated from the results of measurements This work deals with the evaluation of thermal comfort, the measurement of parameters of thermal environment, the evaluating the results of measurements and determining the measurement uncertainty of the sensors. In this thesis, based on these results, were recommended suitable sensors for measuring various parameters environment.

Device Proposal for Measurement and Evaluation of Environmental Thermal State
Janečka, Jan ; Němeček, Pavel (referee) ; Kratochvíl, Zdeněk (referee) ; Vdoleček, František (advisor)
The thesis deals with evaluation of the environmental thermal state in closed rooms with people inside the room. The achievement of thermal comfort is related to thermal balance of human body. People are producing heat during their work, which has to be carried away from the body to surrounding area by radiation, convection, conduction, respiration and evaporation. The intensity of heat removal is influenced by environmental parameters, especially by air temperature, mean radiant temperature, air velocity and humidity. Personal factors as energy expenditure of human body and clothing resistance are influencing the intensity of heat removal as well. People are able to influence the thermal comfort by their behaviour in given environment, appropriate clothing and regulation of basic environmental parameters. CSN EN ISO 7730 standard states that environmental parameters should be estimated or measured. The operative temperature is than evaluated from collected data. This operative temperature is defined as the temperature of black enclosed area where the human body will be by convection and radiation sharing the same amount of heat as in real inconsistent environment. Nowadays on the market there is no cheap solution for sensor which is able to evaluate the operating temperature and could be used in buildings. There are a lot of professional sensors which have very high accuracy, but are very expensive. Therefore are mainly used only for research or for single and exceptional measurement of environmental thermal state in rooms. The thesis is therefore focused on proposal of suitable (compact) operative temperature sensor assembled according to valid regulations and standards. Emphasis is placed mainly on the sensor price together with guarantee of sufficient accuracy. The proposed sensor is providing information to control system which is than able to adjust the parameters of environment using appropriate way based on relevant requirements. Here is some space for energy savings due to possible continuous measurement and evaluation of environmental thermal state in different rooms. Therefore, during continuous measurement no unnecessary rooms overheating in winter as well as unreasonable cooling in summer should occur. This research and solution is than reflected in reduction of energy consumption used for building operation and subsequently reduction of the pollutants production. This issue is being watched with increasing interest. Another advantage is that whole system is able to work autonomously without human intervention. People no longer have to continuously adjust air temperature because the control system is able to evaluate the most appropriate adjustments based on objective data obtained from the sensor. The thesis includes subsequent verification of proposed sensor as well as the definition of sensor technical parameters including analysis of measurement uncertainties.

Family house with a brewery T: O: P in Jevíčko
Němeček, Pavel ; Vávra, Petr (referee) ; Brzoň, Roman (advisor)
Bachelor´s thesis is focused on a project of a detached family house with a brewery T:O:P on a site 88/13 and 88/14 in a Jevíčko. Bachelor´s thesis is drawn in a project documentation for the realization of building. The house has two floors without cellarage, rectangular plan with flat roof, based on strip foundations made of a simple concrete. Vertical frameworks are devised from masonry type therm from Porotherm. Horizontal frameworks are from ceiling panels Spiroll. External wals are warmed by a contact system from polystyrene. Entry into the brewery premises and residential units, located on the second floor, is oriented to the southeast, entrance to the brasserie on the southwest. 1.NP is divided into two service. The service brewery with his technological background and administrative background brewer. The second service is brasserie brewery with his social service and visitors. Housing unit is separated from the brewery and brasserie ceiling constructions and has its own entrance from the open air.
