Cutting tools for deep drilling and their use in practice
Sedlář, Jiří ; Kalivoda, Milan (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis deals with tools for drilling deep holes. The first part is focused on the basic description of the drilling process, sorting the tools according to their construction and last but not least, sorting of the systems used for deep drilling. In the theses is further elaborated an overview of materials for the production of cutting tools and ways of coating, which are used the most nowadays. There is a constant development in coating, because of the better mechanical, physical and chemical properties in this field. The last part is dedicated to the definition of the tools for deep drilling and their use in practice.

Image similarity measuring using deep learning
Štarha, Dominik ; Šeda, Pavel (referee) ; Rajnoha, Martin (advisor)
This master´s thesis deals with the reseach of technologies using deep learning method, being able to use when processing image data. Specific focus of the work is to evaluate the suitability and effectiveness of deep learning when comparing two image input data. The first – theoretical – part consists of the introduction to neural networks and deep learning. Also, it contains a description of available methods, their benefits and principles, used for processing image data. The second - practical - part of the thesis contains a proposal a appropriate model of Siamese networks to solve the problem of comparing two input image data and evaluating their similarity. The output of this work is an evaluation of several possible model configurations and highlighting the best-performing model parameters.

Risks associated with diving and their prevention
DIVIŠOVÁ, Anna
The topic of this bachelor thesis is called: "Risks related to diving and their prevention." The theoretical part is mainly focused on health risks which arise during scuba diving and follow-up prevention of the health risks. Furthermore, the following topics are mentioned in the theoretical part: a history of diving, biophysical concepts, and necessary equipment. Because of this topic, it was important to include chapters about first aid, treatment and medical fitness for diving. A reduction of health risks was chosen as the main objective in the practical part. There were created 3 research questions. 1. What is the training of divers? 2. What is currently the prevention of health damage during diving? 3. How can we reduce the risk of health damage? The qualitative research measurements were used for the creation of the research part of this bachelor thesis. A semi-structured interview containing 24 questions was created to get the data. There were 6 divers chosen for the interviews, 3 professional divers and 3 hobby divers. According to the results, it was found that there is a fundamental difference in the knowledge of the divers about this topic. Very often the risks are caused by insufficient preparedness and knowledge of the diver, not handling of the panic and stress, and a wrong reaction. Disobeying of precautions and principles often contributes to that. The results of this bachelor thesis may be helpful in completing education and information of divers, but also medical staff.

Because of this topic, it was important to include chapters about first aid, treatment and medical fitness for diving. A reduction of health risks was chosen as the main objective in the practical part. There were 5 research questions created. 1. What is the training of divers? 2. What is suitable equipment for diving? 3. What conditions are convenient for diving? 4. What is currently the prevention of health damage during diving? 5. How can we reduce the risk of health damage? The qualitative research measurements were used for the creation of the research part of this bachelor thesis. A semi-structured interview containing 15 questions was created to get the data. There were 15 divers chosen for the interviews, 5 professional divers and 5 hobby divers. According to the results, it was found that there is a fundamental difference in the knowledge of the divers about this topic. Very often the risks are caused by insufficient preparedness and knowledge of the diver, not handling of the panic and stress, and a wrong reaction.
