Risk analysis electrically operated machine
Fiala, Václav ; Hubený, František (referee) ; Pásek, Jan (advisor)
This thesis is concerning analysis of risk and solving them with electrically operand machines, specifically by semi-automatic parking apparatus in terms of design and integration of safety-related parts of a control systems. There are requirements for safety equipment according to DIN EN ISO 13849-1 in this thesis.

Vehicle classification
Fiala, Václav ; Klečka, Jan (referee) ; Honec, Peter (advisor)
This thesis deals with recognition of vehicles with image captured by one camera. The image is always taken as a front view of a vehicle passing one specific place in case of various lighting conditions. The aim is to implement classification method with regard to robustness, reliability and computional complexity. The method is implemented in Mircosoft Visual Studio 2013 using the OpenCV library.

LiFePO4 battery with BMS circuits for a battery drill
Fiala, Václav ; Červinka, Dalibor (referee) ; Vorel, Pavel (advisor)
This bachelor thesis deals with problematics of lithium accumulators. There are listed properties and practical use of lithium accumulators. There is also the chapter of lithium-ion-iron-phosphate accumulators, which will be a practical part of this thesis Next part of the thesis solves a safety electrical circuit system for new lithium batteries which will be able to protect batteries against overcharging or undercharging. In the practical part of the thesis new LiFePO4 batteries for the cordless drill were designed. Also, the mentioned safety electrical circuit was designed and tested.

Možnosti využití badatelsky orientované výuky na středních školách
FIALA, Václav
The inquiry based learning is a teaching method that prefers the interests of the pupils and their own activity. Its structure greatly contributes to the development of various knowledge and skills. Although it uses scientific methodological principles, this way of teaching is a suitable method for all pupils regardless of their future orientation. It develops and encourages skills that are necessary for each person, such as using appropriate information. Due to the poor awareness of teachers in our country, this method faces some obstacles that hinder its successful implementation in education. Furthermore, in fact, a lot of available inquiry based lessons are not research-oriented tasks at all. In this theses, there are described several of successful research tasks, in comparison with some IBE lessons which does not correspond to the concept of IBE. In conclusion, I suggest my own example of the inquiry based lesson plan.

Breeding success of Snow Leopard, Ounce (Uncia uncia) in Zoological gardens.
FIALA, Václav
A snow leopard, specifically irbis (Uncia uncia), is considered as the most endangered species. There are many causes of decreasing population in the last twenty years. The most important are mainly loss of habitat and prey, poaching, agro farming, related conflicts with the natives, and last but not least bad legislation in some countries. Although, the protection has improved in recent years, it is still necessary to increase its efficiency, especially in legislation. Breeding in human care is also one of the most significant implements in protection. For effective breeding it is essential to understand the factors affecting its success. The main aim of my bachelor thesis is to evaluate the breeding success of irbis in the zoos all over the world (except Asia) from data obtained from the International Pedigree Book for Snow leopards (Uncia uncia). Furthermore, my next task is to describe the conditions of breeding in the Czech Republic and specify the chief factors determining the success of rearing. The following facts based on the study of the International Pedigree Book for Snow leopards (Uncia uncia) were ascertained: due to the small number of zoological gardens, there are initially large fluctuations in success of rearing. With the rising natality increases at the same time the mortality. The average success rate is 56,47 %. The percentage of deaths is still high. The breeding conditions in zoos of the Czech Republic revealed that the success of breeding is negatively affected by the high humidity and poorly prepared diet.
