Implementation of drivers for wireless sensor unit
František, Milan ; Šimek, Milan (referee) ; Botta, Miroslav (advisor)
This work is concerned with the use of digital and analog sensors with wireless unit IRIS. There is a basic description of the software stack BitCloud, including important functions with a used sensor types and used buses. In the work is described procedure for creating drivers for the various sensors and their implementation in a stack BitCloud. In conclusion of this work is a practical example of right implementing of the individual drivers.

Distribution of Network Traffic to Multi-Core Processors
Straňák, Peter ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
The content of this thesis is the design and implementation description of the driver for the NetCOPE platform. This driver is required to provide rapid transfer between hardware and software as well as multi-threaded applications. Driver is designed for Linux and is modified so that it allows multiple applications simultaneous access to the card. The paper provides basic information necessary for its adaptation and implementation details of individual features. The emphasis is on high data throughput. The part of the implementation is also a modification of the user library, which cooperates with the driver.

Design of Network Applications for a NetCOPE Platform
Hank, Andrej ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
Monitoring and security in multigigabit networks with speeds 1 - 100 Gb/s needs hardware acceleration. NetCOPE platform for rapid development of network applications uses hardware acceleration card with FPGA technology by means of hardware/software codesign. Increas in performance of platform's software part is dependent of parallel processing in applications to take advantage of utilising more processor cores. This thesis analyses NetCOPE platform architecture and possibilities of parallelising classic network applications and creates models of concurrent access to data in NetCOPE platform to utilize more processor cores. These models are subsequently implemented as extensions to platform's Linux system drivers. Userspace libraries are created to provide simple interface for applications to use these new features. To achieve high throughput of this solution several optimizations are performed. Results are measured by created testing tools.

Porting OpenVPN to Windows CE Platform
Ešner, Oldřich ; Ráb, Jaroslav (referee) ; Ryšavý, Ondřej (advisor)
The motivation for inception of this MSc. thesis which follows on from a term project of the same name was the transfer of the application for building private virtual OpenVPN networks from Windows XP operating system to Windows CE Embedded 6.0 platform. The project deals with virtual private networks in general and looks more closely at its implementation - OpenVPN. It also introduces the basic features of the Windows CE operating system. The project goes on to describe device drivers in NT-based Windows operating systems, the Windows Driver Model used, the NDIS network interface model and also the model of Windows CE drivers - the Stream Interface Model. The project continues with a~description of communication in OpenVPN application and primarily the role of TUN/TAP virtual network interfaces. This is followed by a proposal for transfer of TUN/TAP adapter drivers together with a description of limitations and necessary modifications between both platforms. As a result a TAP network device driver is implemented whose function is verified by test application that emulates the behaviour of a TUN adapter. The project concludes with an evaluation of the achieved results, the possibilities for further work on this theme and with the overall contribution of this project.

Contingency table analysis from questionnaire survey data of drivers
Velacková, Barbora ; Šulc, Zdeněk (advisor) ; Pecáková, Iva (referee)
The bachelor thesis deals with the contingency table analysis from questionnaire survey data of drivers. The data were obtained from the agency Data Collect s.r.o., which conducted the survey in 2014. The aim of the thesis is to analyse the behaviour of drivers and their habits, which could increase the risk of accidents. The thesis is divided into two main parts; in the first one, methods of contingency table analysis are described; in the second one, the presented analyses are applied to the survey data. Firstly, the behaviour of single and young drivers is analysed, then the differences between men and women drivers. Calculations were made using the software SPSS and MS Excel, in which all the graphs and tables were made.

Vehicle usage in emergency medical service stations in the Czech Republic
BRANDEJSKÝ, Miloš
The Emergency Medical Service (EMS) is one of the basic components of the Integrated Rescue System (IRS). The development of the EMS and the usage of new technologies enable an effective emergency management. Ambulances, the emergency service vehicles, are one of the most important aspects influencing the quality of care for a patient. These vehicles ensure the arrival of the EMS personnel on the site of a critical incident as soon as possible, the protection of the personnel, the protection of the patient during he transport and the equipment of ambulances and their size influence the care for a patient. Before the purchase of these vehicles the operation area, i.e. where and on what geological setting they will operate must be taken into account. Also the active and passive safety and technical parameteres must be taken into consideration. The vehicles must also comply with legal norms and norms declared by the manufacturer. Nowadays, when the market is filled with a great number of vehicle producers, vehicles made in the Czech Republic o and Mercedes Benz and Volkswagen are preferred. Specialist firms offer a wide range of car bodies and equipment tailored to the needs of the target client. The objective of the thesis was to compare the performance of vehicles in an operation area and to examine the efficiency of ambulances. The research set was formed by the personnel of the Emergency Medical Service stations in the South Bohemian region. The South Bohemian region was chosen for the diversity of the landscape morphology. The data were gathered by the questionnaire method, the research was anonymous. I set a group of 104 respondents {--} 63 drivers and 44 medical service providers. Questionnaires were composed of questions focused on the respondents´ experience with the ambulance fleet of the EMS. The research was conducted from 4th April to 17th April 2008. Four hypotheses were set: The hypothesis I {--} ambulance drivers prefer vehicles with a classical body, was confirmed. The results are a combination of a questionnaire and a discussion with the EMS personnel. The hypothesis II {--} ambulance drivers prefer vehicles with an enlarged body {--} was not confirmed. 54 % of respondents have enough room in ambulances with a classical body, 66 % have enough room in ambulances with an enlarged body. The hypothesis III {--} in the city traffic the rendez-vous system is being used {--} was not confirmed. According to 54 % of respondents out of the total number of 104 in the city transport cars are being used, but 15 % of respondents use ambulances with an enlarged body and 22 % of respondents never use the rendez-vous system. The hypothesis IV {--} ambulances with an enlarged body have enough room for emergency interventions in the prehospital emergency care {--} was confirmed. 66 % of respondents state that there is enough room in this type of an ambulance, 10 % state that there is not. The research data analysis shows that vehicles used by the EMS are reliable, quality and safety vehicles regardless of their make. Ambulance drivers prefer the vehicles with classical body because they are used to them. They criticise the vehicles with an enlarged body because of the increased width (only rear mirrors are bigger) which is the reason for slow passage in heavy traffic or through densely built-up sites. But the EMS providers prefer ambulances with classical body because they are used to the inner layout. The ambulances with an enlarged body have enough room for emergency interventions in the prehospital care but emergency care providers are not used to another inner layout. The results of my research will be published on newly formed websites {--} health care encyclopaedia {--} section automobiles.
