Use of standard centrifugal pump as turbine
Podešva, Adam ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
This work deals with the use of a centrifugal pump in turbine mode and control of the system where this machine is operated. The introduction describes and divides the various types of pumps and discusses the issue of Euler's pump and turbine equations. The flow control options are also described here. Part of the work is a research that examines the advantages and disadvantages of using a centrifugal pump in turbine mode, the possibilities of using this system and real applications in the Czech Republic and in the world. The main part is the design of a mathematical model in Microsoft Excel, which solves the regulation of the piping system with a pump operating in turbine mode, especially out of the optimal operating parameters.

The used principles of industrial cooling
Machala, Jiří ; Sekanina, Bohumil (referee) ; Kavička, František (advisor)
This thesis summarizes the main cooling methods used in industrial cooling systems. It also discusses the fluids used in cooling, their influence on environment; ozone layer and climate change. The thesis closely describes the properties of ammonia and out of the many cooling methods on the market, it mostly concentrates on ammonia cooling systems. The thesis also discusses heat pumps, vortex tubes, and thermoelectric cooling.

Sevices WCF
ENINGER, Boris
The main goal of this thesis is to acquaint readers with the modern technology Windows Communication Foundation. People who are interested in it can learn via several tutorial lessons how to create and set WCF services. In addition to it, the work describes some techniques of the security service and gives the basic look into hosting area. The problems are explained through visual aids. The sample of audiovisual presentation is available.
