Minimizing the effect of interference on wireless network
Doležal, Jan ; Kyselák, Martin (referee) ; Škorpil, Vladislav (advisor)
This thesis is concerned the technology with technologies of transfer through wireless devices. It is about possibilities of optimization of transfer in wireless net, especially of the reduction of interference influence. The first part is about theory and the standards development of wireless technology. There are methods and principles used in wireless technologies. The second part is a practical measuring and testing of an internal wireless net, with the emphasis being on the source of interference influence. Measuring was focused on interference between access points and was not about meteorological influence. It continues with theory and testing of interference of the microwave oven in our wireless net. Then, it is a practical demonstration of interference in an external environment. There are practical examples of interference between different providers’ nets on the same area and solutions to prevent or to cancel this interference. In next part of work the wireless net is parsed and described in a given territory. Here is described the way how to precede the reciprocal interference and eventually how this mutual disturbance suppress. Consequently, our net is optimized for customer growth and for today’s options of newer and more powerful components for wireless transfer. Finally there are two laboratory tasks. The first one is about practical measuring and testing of wireless net’s parameters and the second one is about simulation of wireless networks in the Opnet program.

Optimization and use of standardized manufacturing routines for the Common Rail Flange production of high pressure pumps.
Doležal, Jan ; Prokop, Jaroslav (referee) ; Píška, Miroslav (advisor)
Objective of the Project of optimization and introduction of standardized procedures in flange production is to plan, determine and introduce optimal procedures based on time scan and MTM analysis; to determine standards, to establish standardized procedures for multi -machine operation and visual control and to train personnel according to new procedure. Project is expected to stabilize process, decrease work in process production, improve quality and increase volume of flange production to 2200 pieces per day for one production line. Furthermore to provide comparison of standardization influence on operations in flange production process, to perform quantitative analysis of several working instructions on visual control workplaces by statistics method (R&R study).

Shares and Their Measurement in Financial Accounting
Vašek, Libor ; Roubíčková, Jaroslava (advisor) ; Sedláčková, Dana (referee) ; Doležal, Jan (referee)
The thesis is focused on a comprehensive analysis of a number of valuation models of shares that are classified as financial assets in the investor's financial statements. The analysis follows the classification according to the level of control and in the structure of the context the valuation models of shares in the existence of the minority influence, significant influence and control, and finally the joint control are considered. The both measurement of shares denominated in foreign currencies and measurement of shares in investor's separate financial statements are also discussed in the thesis. The accounting rules follows primarily the current wording of the IFRS and in certain passages are complemented by US GAAP rules or by Czech accounting regulations.

The analysis of leases according to IFRS
Martiník, Karel ; Krupová, Lenka (advisor) ; Müllerová, Libuše (referee) ; Doležal, Jan (referee)
A lease is used by many companies as an instrument of external financing by which their investing and operational needs are financed. The lease itself is divided under the existing accounting standard IAS 17 Leases - into two parts -- the finance and the operating. The different classification of the lease can be used - position of a lessee and the position of a lessor. The problem in the case of the lessee is that the division into the finance and the operating lease is very sophisticated and also enables the opportunity of the creative accountancy. The reason is that some companies instead of the finance lease recognise the operating lease and conversely. This fact results in a fact that the financial statements are not comparable and users cannot rely on them. This thesis analyses these problems and it is looking for the solutions for the lessees and the lessors.
