Knee system C-Leg and its application to transfemoral amputation
Červený, Jan ; Pavlů, Dagmar (advisor) ; Véle, František (referee)
Title: Knee System C-Leg and its application to transfemoral amputation Objectives: Aim of this work is characteristic of knee system C-Leg prosthetic leg construction with knee system C-Leg applied in patients with transfemoral amputations, the possible setting, used in combination with a common type of Socket and compare the affect of the image of the patient's gait. Another target is a description of possible mistakes in the setting of the C-Leg and their manifestations in the initial use and walking Methods: In this work I used the method of analysis previously identified and published knowledge and experience with the knee of C-Leg, its buildings, the settings recommended by the manufacturer and walk to school transfemoral amputation. Compiling the various types of Socket used to walking training, the published results of therapy in patients amputated and its own experience, I worked under subsequent acts, which occurred during therapy. Results: In keeping with the recommended structure for the transfemoral prosthesis and knee system with the C-Leg and then comparing the different types of Socket and results of therapy in the rehabilitation wards, I described the side effects are possible in the image the patient's gait. The presented findings describe the possible recommendations for the...

Termoregulace lesních mravenců r. Formica na výškovém gradientu
Kadochová, Štěpánka ; Frouz, Jan (advisor) ; Véle, Adam (referee)
This study examines thermoregulation behavior of wood ant genus Formica on elevation gradient. Two years long dataloger records of inner nest and ambient temperature were combined with detailed spring-summer manual measurement of nest temperature in different depths below nest surface. Results show that inner nest temperature was higher than air temperature in all seasons. Temperature of ant nest is highest in the deepest layer, the heat flows from inside out. We can assume that thermal homeostasis of ant nest in spring and summer i.e. in period of ant highest activity is influenced mainly by inner heat sources - microbial activity and ant metabolism. Insulation seems to have direct effect on nest temperature only in early spring; in summer insulation affects nest temperature indirectly, via ant activity. In winter there is pronounced effect of nest volume which corresponds high isolative properties of nest material. Our results indicate that thermoregulatory behavior of wood ants is driven by endogenous factors, namely colony needs in sense of queen oviposition brood development. Both of these require high temperature. Nests at variable altitude did not differ in average seasonal temperature or seasonal temperature fluctuation. Variability of nest temperature was bigger among nests from one...

Business Rules Management Systems
Vele, Vladimír ; Gála, Libor (advisor) ; Pour, Jan (referee)
The aim of this thesis is to evaluate chosen business rules management systems. In addition, it should provide global overview of all business rules area. Crucial definitions and principles related to the Business Rules Management are introduced in the first part of the thesis. The different types ofbusiness rules description, therelation between business rules and business processes, and technology used for BRMS are specified among others. In the second section,the evaluation criteria are created based the previous theoretical analysis. The criteria are divided into groups based on a functionality that should be provided by a business rules management system. The evaluation and its results are presented in the last part of the thesis. The results are discussed and the final conclusion is provided.The thesis can be used as baseline in the decision making process when a business rules management system is to be purchased.

Comparison of open source database systems
Véle, Marek ; Palovská, Helena (advisor) ; Klas, Jan (referee)
Goal of this paper was to compare chosen open source database management systems from theoretical and practical point and assess their suitable use. For this comparison I chose MySQL, PostgreSQL and MonetDB database systems. Theoretical comparison involved licenses covering the systems, available support, supported platforms, usable interfaces and data types. In practical comparison I conducted basic installation and configuration in real environment and tested performance of execution of certain SQL queries. One of the aspects of performance testing was to determine the influence of data storing architecture on speed of execution of specific types of queries. Documentation available with the compared systems and official web pages of particular systems served as the main source for theoretical comparison. I conducted the practical part using the linux platform. To access the systems and for the SQL queries input I used the standard JDBC interface. As data for testing I used random data from Open Source Database Benchmark, which I ordered into two similar tables. I defined the test queries myself in order to compare the performance of database systems in whole and in particular fields. I've reached a conclusion that MySQL is suitable for corporate and stand-alone users thanks to wide support, choice of licenses and diversified spectrum of available interfaces and supported platforms. However, its performance in many fields including index creation and ordering of data was very poor in tested configuration. PostgreSQL can indeed discourage mostly corporate users by worse choice of commercial support and interfaces shipped with the system, but these problems are mostly compensated by active community, or third parties. The performance of PostgreSQL was outstanding, I find it suitable for larger data collections and it's fast even in cases when indexing of data didn't take place. MonetDB, as a not well-known while academically developed system, has little chance for a breakthrough outside its field of origin. Its column oriented storage of data proved convenient when selecting very small number of columns. Even without any indexation all test queries were executed with good speed. Individual chapters of the theoretical part are divided based on the compared systems. The practical part only consists of one chapter divided according to order of actions. At the end of each chapter there is evaluation of discovered facts.
