Motors for automotive wipers
Sekerka, Jan ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
This thesis deals with the innovation of DC motors with permanent magnets used in automotive technology to drive wiper mechanism to reduce the volume and weight of the active materials. Potential innovations is mainly using magnets of the magnetic rare earths, such as Neodym or samarium-cobalt. Another option is to reduce the rotor to decreases the number of threads (here, it's all about, what are the requirements for performance). The result is an innovative motor, wherein the volume of the permanent magnets is reduced by 65% and total volume of the motor by 23% while maintaining the rotor parts. Also slightly raised performance with Neodymium permanent magnets.

Taxi-Dispatch Optimization Due to Effective Usage of Geolocation Services
Sekerka, Jan ; Martinovičová,, Dana (referee) ; Kříž, Jiří (advisor)
This diploma thesis deals with the operation of taxi-dispatch system and possibilities of its optimization by using geolocation services. The introductory part of diploma thesis contains theoretical basis used for an analysis of the current state and for design of an appropriate solution. The analysis of the current state deals with description of dispatch system functions within the selected company, finding weaknesses of the current system and also includes an analysis of market with systems designed for dispatch operation. Based on the analysis has been proceeded to design a custom solution consisting of a mobile application and a server part, which was then put into practice in the chosen company. Diploma thesis is finished by an evaluation of the proposal, which is based on the comparison of the situation before and after the introduction of the proposed solution.

Car Business Through the Internet
Sekerka, Jan ; Martinovičová,, Dana (referee) ; Dvořák, Jiří (advisor)
This bachelor thesis aims to propose a new model for selling cars on the Internet. To illustrate the model is only expressed on the Czech market, but it can be applied to a different market or even a different commodity. The proposed model is based on an analysis of the current state of car sales, which is also part of this work, both virtual and in real environments. For processing the use of theoretical knowledge and e-business analysis methodology for the processing environment.
