The work deals with design solutions to the intake manifold modern contemporary internal combustion engines. Then describes the types of flow and structural design of ports, including the intake of their basic properties. The thesis also compare the results of the analysis and design optimization based on simulation of flow inlet port and measure the actual inlet port.

This thesis focus with construction design intake manifold of four stroke engine rallyecross division 1A. For improvement observant come into operating here derive benefit from theory tuned supercharging, which is based on tuning longitudes sucking conduit. Derive benefit woolen effect. Driving unit is here used four cylinders, water-cooled, atmospheric combustion engine from car VW Polo 6N GTI. Design is created so, to answer condition division 1A.

The aim of this thesis is to consider the operation of dredge pump and design new technology of slag removal including return on investment calculation. The operation optimization itself was preceded by analysis of present technology, data collection, calculation of pressure losses and pinpointing the causes of their origin. Subsequently, the measures to elimination of losses were deduced and these measures were implemented into optimization of dredge pump operation itself. The return on investment into the new technology of slag removal is calculated in the last chapter, considering its feasibility in the heating plant.

There is a description of modernisation steam condensing turbine in this Master´s thesis. Electric output is decreased from 250 MW to 160 MW. This thesis is divided into two parts, there is a calculation of heat balance in first part and a calculation of blading in second part. Detail drawing and heat balance are the most important results of this Master´s thesis.

The thesis is focused on designing of condensing steam turbine with reheating for combustion of biomass. The turbine is developed to be tandem compound-regenerative with five uncontrolled extraction points. Optimization of reheating pressure is made in the turbine's cycle. The turbine outlet is constructed to lead down to the water cooled condenser. Thesis includes the calculation of heat cycle with the draft of flow channel of high pressure and middle-low pressure turbine. Detailed calculation of middle-low pressure turbine, including stress-strength analysis, is performed. The thesis provides an evaluation of flow scheme of 100 % and 75 % of generator’s power output and the drawing of middle-low pressure turbine in longitudinal section.

This master‘s thesis deals with the design of horizontal heat recovery steam generators (HRSG) with two pressure levels after a combustion turbine. In the introduction part is performed thermal calculation and proposal of a heat transfer surfaces. Furthermore, are suggested dimensions of the drums and pipes for flooding and transferring. The emphasis is placed on the fulfillment the required parameters of steam and flue gas at HRSG outlet. At the end is calculated loss of boiler draft and made technical documentation a drawing of the boiler.

The conventional way of cryptanalysis is based on the cryptographic algorithms weak points examine. The attack model of conventional cryptanalysis covers mathematical description of the cryptographic algorithm used. This model is not with the relation to the physical model implementation and the real environment. Cryptographic algorithms currently used in the combination with strong cipher keys are almost unbreakable and the conventional cryptanalysis is ineffective. The new way of cryptanalysis employs the side channels. The model of cryptanalysis using side channels is enhanced with physical revelation of module performing the cryptographic operations. This dissertation thesis deals with cryptographic module description and studies influence of side channels to the security of this module.

This thesis deals with an analysis of a system called Digital Audio Broadcast and describes its mathematical model created in MATLAB program. In the first part basic blocks of a transmitter and a receiver are analyzed along with their principles. Then different types of transmission channels for static, portable and mobile receivers are described. The second part contains description of the DAB mathematical model itself. Individual blocks are described in the order of the DAB signal path, from the transmitter through the transmission channel to the receiver side. In this part the graphical user interface is also described. In the final part the results of experimental measurements and simulations are presented.

The work is mainly concerned with the possibilities of breaking the encryption algorithm AES with using of non-template attacks. In the introduction are listed techniques of differential analysis, which are using in the present, but for the sake of completeness is there mention about simple power analysis. In the next chapters are briefly described countermeasures against power analysis and further is described the AES algorithm. Most important parts are chapters where are described attack implementation on AES-128 through correlation power analysis and mutual information analysis. These attacks exploit power traces from www pages dedicated to book Power Analysis Attacks - Revealing the Secrets of Smartcards, http://DPAbook.org and especially to power traces from DPA Contest 4.2, http://www.dpacontest.org. In conclusion is comparison of methods based on the number of power traces needed for finding the key of secret message.
