Blízké pole dipólových antén / Near field of the dipole antennas

Beran, Vlastimil January 2010 (has links)
The thesis describes the radiation of dipole antennas in near field area. More methods for evaluation of spatial dipole field arrangement are compared. The work target for practical use is to create software for simulation of near field values placed in planar or cylindrical observation plane. The computer programme is applicable to single dipole or dipole array. The limits for human body exposition of non-ionizing radiation are here implemented for compliance purpose in hygienic evaluations. The simulated results of field distribution are possible to display as graphs or save to data file. The results of own calculation are compared with results obtained by some commercial software as well by measurement of field components under model conditions.

Monitoring podmínek pro lední hokej mládeže ve vybraných hokejových klubech v menších sídlech / Monitoring circumstances for youth ice hockey in selected hockey clubs in smaller towns

Kobzová, Tereza January 2014 (has links)
Title: Monitoring circumstances for yourth ice hockey in selected hockey clubs in smaller towns Purpose: Main aim of diploma tesis is to decribe situation in selected ice hockey clubs in Czech republic. Visited clubs were choosen by small numbers of members in youth categories of ice hockey players. Huge effort of the diploma tesis is detect causes unsatisfactory situation in clubs and suggest the best solutions to expansion and development youth membership. Methods: Survey is based on depth and sturctured interviews with the expert guidance of the clubs and the mayors of the cities. Next method used in diploma tesis is utilized content data analysis. Thanks to using these two methods was formed qualitative research, which was summarized and described in 18 case studies. Results: Both methods are qualitatively processed in case studies. There are carefully and accuratelly reasons of decreasing youth membership in ice hockey clubs. There is also decribed way of solution. Collected data include envely research and results could be aplicated to the whole territory of Czech republic. Keywords: ice ring, sports facilities service, funding clubs, membership development

Smart shop banner - nový marketingový nástroj / Smart shop banner - new marketing tool

Gotthardt, Martin January 2011 (has links)
This thesis deals with a new marketing tool for campaigns to support product sales at the point of sales. Banner can appropriately draw customer's attention and also persuade to unplanned impulsive purchase. It is a plastic pocket that can hold posters to support individual product or brands of companies and also can be changed quite often. Uniqueness of the solution lies in the location of the advertising space. In case an LCD monitor is part of the cash register, the banner is located on the other side directly exposed to the eyes of customers. The aim of the thesis is to present a new marketing tool and ideally prove that the right use of visual communication means is able to encourage impulsive purchases even in the environment of a Czech bank. Even though it was not completely proven that the banner can encourage impulsive purchases in banks, the whole concept has been prepared, it's potential revealed and the possible effective uses for normal practice have been formulated.

Peer to peer systém pro vzdálené ovládání počítače

LEJTNAR, Michal January 2017 (has links)
This thesis deals with creating of decentralized peer to peer system designed for remote control of computers. P2P network and single nodes in this network is inspired by hybrid peer-to-peer network architecture used by Skype application. The application uses terminal services available in operation system Windows for remote control of computers. Namely, MS Remote Desktop and MS Remote Assistance is used. The entire application is created in programing language C#.

Vliv vodních ploch na návrh nového uspořádání pozemků ve vybraných pozemkových úpravách. / The influence of water areas on the proposal of a new land arrangement in selected land adjustment.

JAROŠOVÁ, Kamila January 2013 (has links)
My thesis is focused on the influence of water areas on the proposal of a new land arrangement in land adjustment. I chose the cadastral area of Žár u Nových Hradů and Netřebice. I made the work by comparing maps of land cadastre, land register and comprehensive landscaping project, where I focused on the comparison of changes in arrangement and area of ponds and reservoirs with adjacent land and changes in ownership.

Internetové ovládání laboratorních modelů / Internet based control of laboratory models

Dobrovolný, Petr January 2011 (has links)
This award solves design of two models that are designed to teach on PLC and in the future on the Control Web. Both models should be used in LabLink system, which allows you to remotely working on laboratory tasks. The first software model simulates the movement of trains on rail in relation on control from the PLC. The second model is a physical model of drill. In both models are solid managing and type of construction, which allows operation without physical intervention.

Planární fraktální filtr na substrátu s porušenou zemí / Planar fractal filter on defected ground substrate

Kufa, Martin January 2012 (has links)
The diploma thesis is focused on the design of planar filters combining fractal layouts and defected ground substrates. The diploma thesis can be divided into three main parts. First, basic knowledge about fractals is presented (creation of Minkowski Island and Koch loop, e.g.). Then, the principle of defected ground structure is described, and a combination of fractal motives with a defected ground structure is briefly introduced. Properties of investigated structures are verified by CST Microwave Studio and Ansoft HFSS. Second, different defected ground structures under the 50 transmission line are designed, and conventional equivalent filters are created. Filters are simulated and compared. In final, the investigated filters are recalculated for the substrate Arlon 25N, simulated, manufactured, measured and confronted with a conventional filter on the defected ground substrate.

Projekční návrh ohříváků topné vody pro výměníkovou stanici 200 MW / Design of heating water heat exchanger, capacity 200 MW

Vašíček, Jakub January 2014 (has links)
The thesis is focused on the design proposal of thermal heaters for heating water in heat-exchanger station with a total output of 200 MW. The aim of the work is conceptual design of heat exchangers, thermal and hydraulic design of individual heaters and preview of flow of mass and energy. The outputs of the work are written calculations, design drawing of one heater and design of a heater arrangement in exchanger station. The objectives of the work are filled completely. The work is focused on issues directly related to the actual design of heat exchangers, does not give a general overview of the topic. Thermal calculation is limited to the calculation of heat transfer surfaces for condensation of steam and condensate hypothermia.
