Aspects of Optimality and Balance Evaluation of Corporate IS
Neuwirth, Bernard ; Koch, Miloš (advisor)
This doctoral thesis deals with the aspects of evaluation of balance and optimality of corporate information systems. The initiative for this specialization was given by the increasing importance that is being laid on the perception of information systems from the point of view of a business company. More and more resources are being invested in the domain of information systems, but afterwards, it is not always ascertained that the information system is such a system, one could characterize as balanced and optimal for the company today as well as in the future. Often this is because there does not exist for the company an available and easily applicable methodic how to evaluate the system. As one of the main starting points of this doctoral thesis I have chosen the methodic HOS8 that was published 5 years ago on our faculty. The newly proposed methodic HOS2009 is trying to clear up the weak points of the original HOS8 methodic that were discovered during its practical use. This is done mainly by using the information feedback from the applicants of the methodic. Within the scope of this thesis the factors influencing the level of the particular areas of the system and the influence of these areas on its general balance are being examined. With regard to the evaluation of the balance and optimality of the information system, in this thesis the problematic of determination of a balanced and optimal state of information system for a company nowadays as well in the future are being examined. As a part of the methods output the thesis presents also charts representing the general state of the system, the imbalance of the particular parts of the IS and the relationship between the areas of hardware and software. Based on the evaluation of the current state and its comparison to the balanced optimal state for the present day as well for the future, the new possible directions and strategies of further development of the IS in the company are being proposed. I see the best exploitation of the methodic HOS2009 in the company in the support of managerial decisions with impact on: the discovery of potentially problems within the scope of IS of the company, the design of a possible course of development useful for their solution, but also the usage of the methodic as a simple control mechanism.

The Innovation of Order Management in the Company
Volná, Tereza ; Pfeifer, Marcel Rolf (referee) ; Putnová, Anna (advisor)
The bachelor thesis is focused on the design of a new innovation in a predetermined company. The theoretical part deals with concepts related to innovation and information systems of companies. The analytical part is focused on basic information about the selected company and the current state of awarding contracts. In the last part, a new system of awarding orders is proposed, which should help to assign tasks more efficiently and at the same time better organize the company's schedule.

Luminaires and Applications with Power LEDs
Vaňko, Adam ; Pavelka, Tomáš (referee) ; Baxant, Petr (advisor)
Progress in development of modern LEDs, their long lifetime and high luminous efficacy predetermine them for usage in lighting systems. This master's thesis examines possibilities of application of LEDs in luminaires, parameters of diodes and problems, which can appear in construction of luminaire with LED lighting source. In the practical part of this thesis a luminaire is designed, capable of illuminating traffic signs, vertical surfaces, billboards and fasades. By standards required parameters of a lighting system and adaptability of application must be considered in complex predesign. Simulations of lighting scene, created in special computer software, measurements of optical point’s parameters and construction of real luminaire model using high quality CREE LEDs, are included in analysis of the problem. Parameters of the luminaire were proved by measurements of product’s attributes at light laboratory. There are also some suggestions for improvement and further development of the product.

Charger for small accumulators
Dvořák, Pavel ; Zeman, Václav (referee) ; Kolka, Zdeněk (advisor)
Work will address the characteristics of small batteries. They are described types of charging process, charging time and charging currents, depending on their effectiveness. Great attention will be directed to draft Chargers, working in the area of continuous or discontinuous modes. Furthermore, the calculation of individual components and their influence on the running drive. The charger will be simulated by PSpice program and powered photovoltaic. Work will focus on the maximum efficiency when the incident light intensity. With related setting maximum efficiency and maximum power tracking using microprocessor-controlled detention. The charger will detect the input voltage, battery voltage and current. Depending on these values will be changed duty cycle PWM.

Data Backup and Data Storages
Šebo, Martin ; Luhan, Jan (referee) ; Kříž, Jiří (advisor)
This bachelor’s thesis is oriented at backing up, recovering and cloning of data, while also on various types of data storages and their usage in the company Lorion Insurance a.s.. It’s also focusing on issues arising from the company’s current state and on solving them. The output of this thesis resides in a design of a more effective, reliable and better secured sys-tem for storage and management of data.

Heat Exchangers
Rosypal, Štěpán ; Fortelný, Zdeněk (referee) ; Baláš, Marek (advisor)
This bachelor thesis shall inform readers about basis types of heat exchangers used in power industry and their basis sorting. They are sorted not only from the point of view of their purpose and function, but also, from the point of view of their construction. Apart from that, there is a comparison of recuperative heat exchangers. Moreover, the thesis deals with possibilities to enhance their efficiency, possible problems in service and ways to solve these problems, maily with sedimentation and cleaning heat exchangers.
