This thesis deals with the problems of wounding of low potential transferred from steam turbine condenser. First, in the theoretical part variations of steam condenser design are described. Then there is a description of variations of cooling cycles and possibilities of their operation range. In second part of the thesis there are two common cooler options chosen. Those are wet cooling tower with natural draft and dry chiller with forced draft. Two types of cooling liquid are chosen to be used for dry cooling. These are water and the other one is 50 % mixture of water and propylene glycol. Based on the calculation results of both cooling cycle variations appropriate pumps are chosen, fan for forced convection respectively. Parts of the thesis are also projection drawings for both calculated variations.

This thesis deals with the construction of an active transtibial prosthesis for recreational swimming. Its aim is to create a working sample of such a prosthesis. The device will primarily serve the patient to move in water - it will be attached to the stump and it will be driven forward. Secondarily, the prosthesis can be used for walking, in the sense that the patient attaches the prosthesis near to a water surface (pool, lake, ocean) and comes with it to the shore. As part of the design and electronics it will be necessary to determine the characteristics of the human resistance in water depending on speed and to determine the necessary propulsion (thrust) strength of the propeller, which will serve as the driving force. Subsequently there will be formed structural variants and selected the best one. This will become default for design and construction of simplified testing device, which will be tested for static thrust. After verifying the functionality and reliability, the final functional sample will be manufactured and tested too.

Controlled deformation. Under with conditions can the iron deformation process be affected? This work is focused on expanding steel profiles. Using various tests, I will confront the visual results with the technical possibilities of the material. Attempting to find a boundary that is still permissible in terms of maximum steel loading just before the material starts to fail. The resulting installation should show the enormous forces needed to distort the material, where the viewer will be directly confront with the process.

The long-term performance of TAH pumps needs to be demonstrated. Reliability tests are performed to measure its ability to operate for months, or years, without failure. Real Heart is currently constructing test rigs for this purpose. Software for documenting test rig conditions is also required. Thus, the objective of this study is to assist in developing reliability test rig software.  The software is written in LabVIEW and is hosted on a CompactRIO controller. Requirements include sampling of sensor data, logging, and alarms. Additionally, a PC dashboard is constructed for monitoring real-time data, reviewing logs, as well as controls for acquisition. Results of this study present a foundation for the test rig software. It features a modular architecture which allows for future scalability. The process of development involves research of hardware/software, establishing a reference design and to build and validate each module through test simulations. Data acquisition is set up with the NI-DAQmx API. It features automatic configuration for thermocouple, as well as custom signal scaling of the pressure and flow transducers. However, grouping of data and synchronization for logging and alarms was a challenge. The producer/consumer design pattern is implemented for grouping data as well as synchronization for logging and alarms. / Det artificiella hjärtats långsiktiga prestanda måste demonstreras. Tillförlitlighetstester utförs för att mäta pumparnas förmåga att fungera i månader eller år utan att gå sönder. Real Heart bygger för närvarande testriggar för detta ändamål.

Resultaten av denna studie utgör en grund för testriggens programvara. Den har en modulär arkitektur som möjliggör framtida uppskalning. Utvecklingsprocessen involverar studier av hårdvara/programvara, upprättande av en referensdesign, samt att bygga och validera varje modul genom testsimuleringar. Datainsamling genomförs med NI-DAQmx API. Den har automatisk konfiguration för temperatur, samt anpassad signalskalning av tryck- och flödesgivare. Designmönstret producent/konsument implementerades för gruppering av data, samt synkronisering för loggning och alarm.

Diploma thesis Gender Equality Implemented by Gender Segregation: Analysis of TV show "Tah dámou" deals with an issue of gender segregation. The theorethical part of the thesis presents results of academic researches of feminist media studies covering the topics of women's representation within media contents and women's status within media institutions. History of different feminist's approaches is described and followed by definitions of sex/gender. The thesis provides discussion of different approaches to gender equality from different feminist's points of view. The study also examines how feminism is presented in the media content in the Czech Republic and abroad as well and how feminism is evaluated by journalist in the newsrooms. Analysis of Tah dámou TV show focuses on both the TV producers (contributers) and media response that the show provoked after its launch in 2011. The results of analysis revealed that the gender segregation was motivated by underrepresentation of women in media and public sphere. The authors tried to equilaze "women's voice" to "men's voice" in the manner of the second wave of feminism. The authors defined cathegory of "women" through common women's life experiences. Criticism of segregation character of the show appeared in the analysed articles. Journalists pointed...

Millions of people suffer from heart failure worldwide. The need for heart donations started the development of mechanical circulatory support systems. A suction phenomenon can occur in the artificial heart when not enough blood is available. Due to occlusion, suction in the artificial heart can cause the arteries to collapse and have fatal consequences. This thesis is in collaboration with Scandinavian Real Heart AB and follows the implementation of a preemptive atrial suction detection algorithm for the total artificial heart (TAH) developed by Realheart. The main limitation is the number of sensors available to collect data from, restricted to a pressure and current sensor. The data used in the thesis is collected on a mock loop that simulates the pressures in the human body. The implementation follows an iterative process where different Artificial Intelligence algorithms are tested and evaluated. The final algorithm uses a recurrent neural network (RNN) for classification and is evaluated based on the accuracy and the number of seconds before suction occurs. The results show that the RNN can preemptively classify the data one second before it occurs. The algorithm assumes suction to happen one second before it occurs, preemptively detecting suction. The results from this thesis enable a continuation that can improve the development of TAHs. Future work includes an addition of features for a more accurate and robust algorithm, a more diverse dataset, an improved labelling process and the addition of a time axis to the RNN to improve the time before suction is detected.

This dissertation thesis deals with the computational modelling of the dynamic response of the rotating electrical machine structure on the application of the magnetic forces. Apart from the dynamic response of the ideal symmetrical machine, the influence of the air gap eccentricity on the dynamics response is studied in this work. A basic type of the air gap eccentricity, which is caused by eccentric mounting of the rotor pack on the shaft of the rotor, is considered. The calculations the dependence of the magnetic forces on the time and a misalignment of the rotor pack are performed as first. The computational model of the magnetic field of the rotating electrical machine, which is based on solution of the electromagnetic coupled field analysis by finite element method, is used for this purpose. An analysis of the influence of the unbalanced magnetic pull and the stiffness of some parts of the machine on the modal properties of the machine is performed in the second part of this thesis. A third part of this thesis is focused on the calculation of the dynamic response of the machine during the steady state operation of the machine and the influence of the rotor pack misalignment on the dynamic response is studied. The obtained results showed that the tangential components of the magnetic forces, which act on the stator pack, excite significant torsional vibration of the stator. Besides the vibration of the stator of the machine, the influence of the rotor pack misalignment on the sound power of the machine, vibration of the rotor, loads of rotor bearings and air gap eccentricity is studied in this thesis.
