Analysis of a Corporate Information System and Proposal of Changes
Křepela, Jakub ; Šimka, Dalibor (referee) ; Dydowicz, Petr (advisor)
The main issue of diploma thesis is information system and it's influence to effectiveness and productivity of work in the concrete company. Main aim is to suggest a recommendation that will lead to increasing the effectiveness of the company work. The thesis is separated to three parts. Theoretic part engaged the information systems most important sections. The real problems are detected in the analytic part and in the practical part are the recommendations on improvement current situation.

Suggestion for the Improvement of the Company´s Culture
Křepela, Jakub ; Havlena, Petr (referee) ; Pokorný, Jiří (advisor)
The bachelory work is engaged in problems of company's culture and it's influence to effectiveness of the company work in concrete company Triga color, a. s. The aim is to suggest a recommendation that will lead to increasing the effectiveness of the company work. This work consists of theoretic part, which includes the company's culture description and individual elements description. In the practical part the results of the research are presented and the recommendations on improvement current situation are proposed.

Dynamic Behaviours of the C Axis Drive for Multifunction Cutting Center
Křepela, Jan ; Marek, Jiří (referee) ; Souček, Pavel (referee) ; Brychta, Zdeněk (referee) ; Singule, Vladislav (advisor)
his Disertation thesis involves the creating of the simulation model of the C axis drive over mentioned machine and them verification on the prototype of this machine. C axis is controlled with position feedback. Simulation model was created before the realisation of the machine prototype for the preliminary identification of the dynamic behaviours in the working cycles and them opportunity of the realisation this conception. C axis is constructed with worm gear and is controlled with help of Master-Slave drive. This torque drive eliminates the production backlash in the worm gear. The multifunction turning center, where is used this C axis, is determinate for heavy duty roughing cutting of the forged peaces, where is problem with dynamic stability of the cutting process. Simulation model includes the problems with multi-body mass system, friction on the worm gear, self locking, damping on the worm gear and the optimization of the parametrs for many regulators. Simulation model was verified on the prototype of the machine. Achieved results bring the new knowledge, which are used for simulation complicated machine nodes and this knowledge is used for research and developing of the similar mechatronics system.

SOA and cloud computing
Křepela, Josef ; Karkošková, Soňa (advisor) ; Feuerlicht, Jiří (referee)
The primal goal of the bachelor thesis is describe principles of cloud computing, properties of SOA (service oriented architecture), their synergy following SOA Governance. At the beginning theoretical part will be described some important concepts and principles of cloud computing, there will be described deployment models and service models, SWOT analysis. In the next chapter is analyzed service oriented architecture. The third chapter describe the common features of cloud computing and SOA, synergy. The last chapter deals with governance of SOA (SOA Governance). Practical part of the work is modeling of SOA governing processes continuity with service cloud provider.
