Optimization of motocross sidecar chassis
Švihálek, Petr ; Fojtášek, Jan (referee) ; Tobiáš, Martin (advisor)
This bachelor's thesis deals with the design solutions of shock absorbers in the motorcycling discipline of sidecarcross. A research of various construction variants of shock absorbers was conducted, along with their measurements both in laboratory conditions and during training rides. The thesis explores the influence of basic adjustment elements of shock absorbers on their performance. The measurement results are analysed and presented using graphs illustrating the distribution of shock absorbers in the reaction area of normal compression and in the response area of the HS regulator. The theoretical part of the thesis provides basic information about sidecarcross, the history of shock absorbers, and their function. The practical part focuses on the installation of equipment and field measurements. The acquired knowledge is utilized to formulate recommendations for the optimal adjustment of shock absorbers, which can positively affect the riding characteristics and performance of racing specials.

Setting the Communication within an Organization from the Perspective of the Organization's Management and Individual Workers
BICEROVÁ, Markéta
The diploma thesis deals with the topic of communication settings in organizations and summarizes its settings in three arbitrarily selected organizations. The diploma thesis has two goals: to find out how communication is set up between management and individual workers in organizations and to map whether and how supervision takes place and how they help in setting up communication between workers. The research is carried out using a qualitative research strategy using a semi-structured interview. An arbitrary selection method is chosen for the selection of the research set. The research team consists of 11 employees, of whom two employees are in the position of the director of the organization and one is in the position of service manager. The analysis of the results is done by open coding and axial coding, and a paradigmatic model is created. The obtained data is processed in the Canva program. Data analysis shows how employees perceive the communication settings in the organization in which they work, what benefit they have for the employees of the organization and whether they help to improve communication between them. Employees of organizations perceive communication as very important; they continuously work on the quality of communication and try to improve it. They perceive supervision as an integral part of the high-quality operation of the organization and at the same time they perceive that supervision helps both in improving internal and external communication, as well as preventing burnout and contributing to the psychological well-being of all employees. The diploma thesis contains a subjective evaluation of the quality of communication between workers, evaluation, and benefits of supervision, which can serve as feedback for organizations in which the issue of internal communication or the issue of supervision is addressed.

Controlling of programmable analogue circuit
Sobotka, Josef ; Hanák, Pavel (referee) ; Vrba, Kamil (advisor)
This work deals with the design of the control software for the programmable analog circuit adjustable by means of a computer via the serial interface for the computer, as well as for programming the microcontroller. In addition, analyses the internal structure of programmable analog circuit on which it is proposed to further control, design of printed circuit boards for final programming and test equipment and measurement of the basic parameters of the circuit (transmission and phase frequency characteristics of parts and units).

Mobile applications development for remote control of instrumentation
Macek, Michal ; Křivík, Petr (referee) ; Frk, Martin (advisor)
The presented work describes the growing trend of using mobile devices to control laboratory instruments and displaying of measured data. The main objective is the application development for mobile devices, which will allow to remotely control and measure with laboratory instruments. The practical part is focused to programming mobile application which will be able by using the local network to connect multiple laboratory instruments, setting them for different types of measurements and then display measured data.

Analysis of data transport in converged network
Menšík, David ; Hošek, Jiří (referee) ; Škorpil, Vladislav (advisor)
This thesis deals with data transmission applications in the converged network, focusing on the WiFi network IEEE 802.11. The theoretical part describes the cause and nature of converged networks. One chapter is devoted to a description of IEEE 802.11, which is next to different standards and options described architecture, coordination and access network QoS solution to that standard. The research is based on custom design converged networks, and WiFi elements in the environment of graphic simulation software OPNET Modeler. In the proposed network was also simulated the operation of services such as voice, video conferencing, FTP and HTTP streaming. Results of simulation data traffic in the network are then analyzed. At the Conclusion of the thesis, is in OPNET Modeller program created the role of laboratory. The essence here is the comparison of operating a converged network, with and without quality support services.

Implementation of multi-purpose server based on WINDOWS
Depiak, Petr ; Kouřil, Jiří (referee) ; Pfeifer, Václav (advisor)
This thesis puts brain to the pieces of knowledge of the network services which are occurred in the server systems. These services are related to data storing, transport and data interpretation. Basically there are transport services which are used by FTP and SMB protocols. These protocols define them generally and their security too. Next section describes principles and application possibilities of electronic mail. It is based on SMTP, POP3 and IMAP protocols. The important part of this thesis is the World Wide Web service exploiting the HTTP protocol. It also refers to creation of dynamic presentation of electronic document by using the MySQL relational database and PHP script language. Practical part goes out of the theoretical part discussed above and all services are implemented on the MS Windows 2003 Server EE R2 platform. The main scope is oriented to the highest usage of data security within the available software. Other part presents the introduction to hosting of the Novell eDirectory service. It is practically applied on the MS Windows platform. This application also includes the administration of eDirecroty service by using the standard tool. This tool allows the administration though the web interface.

Traffic Management in UMTS Network
Menšík, David ; Novotný, Vít (referee) ; Hošek, Jiří (advisor)
This thesis is describing UMTS network, architecture and especially maintaining Quality of Services in this network. Specifically is focused on operation control management in UMTS network. Practical part contains description of settings for UMTS network with QoS and following operational simulation. This simulation was performed in OPNET Modeler v.14.5. Others simulations were performed with different settings of QoS. Results of three simulations were compared and by that operational dependence on QoS settings was verified.
