Spread-spectrum Communication System
Machala, Pavel ; Šimek, Milan (referee) ; Číž, Radim (advisor)
The thesis focuses on issues around communication system with the Direct Spread Spectrum Signal Signal. This work outlines the theoretical analysis of this technique and subsequently is created a communication system concept. The device concept is adjusted so that the device can be used as a laboratory device, presenting the spreading technique. This thesis offers a comprehensive and detailed description of the communication system construction, including design of transmitter, receiver and a common transmission channel. In conclusion are stated the results of devised communication system.

Electronic tester of capacity and internal resistance of batteries and accumulators
Machala, Pavel ; Kubánek, David (referee) ; Lattenberg, Ivo (advisor)
This work deals with the design and realization of electronic tester of capacity and internal resistance of galvanic cells. In the begining is situated the familiarization with basic concepts and features of galvanic cells. There are also described appropriate methods for measuring capacity and internal resistance. These principles are aplied into the design of electronic tester which is described in detail in the next chapter. The designed device is controlled by a microprocessor chip ATmega16, whose software is thoroughly described in the second part. In the end you can find the results of testing and assessment of these tests.

Diving Group of the Fire Rescue Brigade of the South Bohemian Region - activities, training and education
MACHALA, Pavel
The diploma thesis focuses on the Diving Team of the Fire Rescue Service of the South Bohemia region. It concentrates on its activities, technical gear, staffing, related law regulations and internal files of the Fire Rescue Service of the Czech Republic, more precisely of the Fire Rescue Service of the South Bohemia Region. One of the main law regulations, which define tasks of the Fire Rescue Service of the Czech Republic, is currently Act No. 320/2015 collection about the Fire Rescue Team of the Czech Republic and about the changes in some laws. In order to fulfil all the tasks and duties, it is necessary to be well trained in specialized fire rescue skills, without which the above mentioned could not be performed. The examples of these skills are the skills of the Diving Team of the Fire Rescue Service of the Czech Republic. Their main assignments are mainly rescue works, which are supposed to be fast and effective response in protection of human health, life, possession and environment, which require activities done under water surface. The members of the team the divers must deal with a high number of unfavourable circumstances and negative leverages. They not only make their work more complicated but also put their health and life at risk. For all the above-mentioned reasons this work requires real professionals with the best theoretical and practical training, supported by the best quality and heavy-duty gear. The divers spend most of their working time in dark, cold and mentally demanding environment; in environment containing harmful chemical and biological substances. They work on places where they are confronted by circumstances that enhance the already demanding working conditions. As their scope of activities is always under water surface they are constantly exposed to environment which places demands on their physical adaptability, and in which they must rely solely on their own abilities and reliability of their colleagues. On top of all the previously mentioned, the fire fighter diver must carry out all his tasks and assignments on the place of intervention where he is constantly under the threat of change of conditions and subsequent occurrence of a hazardous situation. In view of all the above-mentioned facts, the diver must demand on psychological endurance, perfect physical condition, above-average health condition, high technical skilfulness, and efficiency in thinking. Therefore, the fire fighter diver must be a real professional in his field. He needs a complete theoretical training, complex gear and perfect physical training, so that no unexpected situation would result in fatal consequences while performing the required task on the place of intervention in its full extent. The aim of this diploma thesis is to assess the activities of the Diving Team of the Fire Rescue Service of the South Bohemia region, verification of the sufficiency of the theoretical and practical training, as well as screening of the facilities and gear with respect to the capacity of being placed on duty in order to perform rescue operations. The assessment of the work carried out by the Diving Team in this diploma thesis is based on retrospective view at the activities performed by the Diving Team during their interventions and their professional look at the stated issues. After processing of the information from the reports about the interventions of the Diving Team of the Fire Rescue Service of the South Bohemia region for the period between January 1st 2006 and December 31st 2015, structural dialogues with the members of the Diving Team were carried out as a follow-up activity based on the results of the processing. These dialogues provided valuable information for possible suggestions and recommendations for alterations of the internal files of the Fire Rescue Service of the South Bohemia region and proposed some modifications to the equipment available to the group.

The use of hydraulic rescue equipment
MACHALA, Pavel
The aim of the presented bachelor thesis is to compare the usability of hydraulic and electrohydraulic rescue tools during car accidents or people rescue. The main category of electrohydraulic tools at which this thesis is aimed is the category of battery-powered rescue tools. These are not-so-typical rescue tools which, in my opinion, have a great future. They have many advantages for the rescuers, but they have not been in use in the Fire Rescue Service of the Czech Republic so far.
