Detection of attacks targeted at web applications
Jégrová, Eliška ; Gerlich, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
This thesis is dealing with vulnerabilities of web applications. The aim of the work is to create tools for attack detection of certain attacks, specifically Same Origin Method Execution (SOME), XML Signature Wrapping attack, XPATH Injection, HTTP Response Smuggling and Server-Side Includes (SSI) injection. Another aim is to create logs that display detected attacks. In the first part, the theory is analyzed and vulnerabilities of chosen attacks are described including their misuse. In the next section there are web application implemented which contain vulnerabilities for successful execution of the attacks. Furthermore, in Python language detection methods are designed and developed for these attacks, which are accompanied by a log entry.

Experimental testing of hydroinsulating injection screens efficiency in dependance on properties of building materials
Červenka, Martin ; Černý, Vít (referee) ; Drochytka, Rostislav (advisor)
The most of the buildings are almost always faced with moisture in our climate. In the past, the humidity was reduced and conducted only by mechanical methods. Over time, chemical wet masonry method also known as chemical infusion curtain was invented and introduced into practice. This method involves the creation of boreholes at a selected height of humid masonry. These boreholes are impregnated with special solutions. These solutions in humid masonry fill pores in the field of boreholes and thanks to this subsequence the monolithic waterproofing curtain is created. The objective of this work is to determine the methodology for verifying effectiveness of various types of waterproofing injection curtains depending on the properties of the various types of building materials.

Production technology of plastic porter for ammunition
Hejl, Dušan ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
Dissertation deals with solution of production of set component „plastic porter for ammunition“. Component is made from high-density polyethylene with business marking LITEN ML 77, suggested series of 3 000 000 pieces. On the basis of literary study of plastics injection problems and necessary calculations, there was proposed injection form. This form is solved by means of normalised components from company Meusburger. There was chosen injection machine from company Arburg Allrounger 370 S 700 – 170.

Three-phase sinusoidal pulse width modulation algorithms
Rudolf, Ladislav ; Červinka, Dalibor (referee) ; Klíma, Bohumil (advisor)
The main theme of this bachelors‘s thesis is to introduce readers into the algorithm of generating three-phase sinusoidal pulse width modulation. Main attention is concentrating to methods of generating Pulse width modulation method such as comparate PWM modulation technique and space modulation of voltage vector SVM. The functional units of algorithms are analysed and described from the basics. In addition, this project describes the basic analog solutions and even the implementation of the PWM modulator into signal processors DSP56F800.

Optimizing injections from the condensate pump
Kordiovský, Jan ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with the topic of the optimization calculation of the mass flow of injection from the condensing pumps of the second degree to the condensate of heating steam, flowing from the system of separation and reheating, with the main goal to achieve the maximum power of the block of the power plant. There is calculation of the secondary circuit of the nuclear power plant in Dukovany before and after the optimization. In the next part, there is calculated growth of electric power of the block, results are drawn in diagrams and technical solution is designed.

Injection System Build-in on Tractor Engine
Svršek, Michal ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
The aim of this work is to design the installation of a new injection system to the existing tractor engines and construct new components necessary for proper function of the injection. In the following section is suggesting the location of other accessories for engine control. This is an injection system with a pressure reservoir "Common Rail" and all its components are created in modeling environment PTC Creo 2.0. Designed components are tested for strength and they are subjected to modal analysis.

The development of grouting for additional sealing of embankment dams
Michalčíková, Magdaléna ; Klablena,, Petr (referee) ; Drochytka, Rostislav (advisor)
Seal of sand or gravel by chemical injection is known and used for a long time. Chemical grouting are however expensive and sometimes the use of cement does not lead to desire effects. So it is trying to find new materials and methodologies injection arrangement works. To achieve savings of chemical products are added to a mixture clay and cement. Clay-cement grouting mix are used not only in order that they are better quality, but also because in this way proposed mixtures have a tendency to penetrate better into incoherent sediments that need additional sealant of chemical injection. For further possible reductions of economic terms the mixture is trying to replace the classic clay. As a suitable substitute for classic clay is to a certain extent the use of secondary raw materials. Above all it is fly ash. As a part of my thesis I deal with the appropriateness use of these materials and examining their properties in the mixture. It was found that by using fly ash were improving consistency of the fresh mixture, reducing the amount of water-cement ratio and reduce shrinkage of the mixture. On the other hand, by using fly ash has been increasing decantation, permeability atc. In the next stage of my work was examined the influence of the quality of cement, lime and liquefaction in the mixture. The aim of thesis is to propose the optimal injection mixture for additional sealing earth dams.

Fuel Injection Analysis
Schnabl, Jan ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
The ignition and injection system in any form are an integral part of each car. The development of these systems goes hand in hand with the development of the automobile and his growing industry. Since the nineteenth century to the present occurred in this sector signifcant progress. This thesis is focused primarily on the description of the two systems and their partiton. The development has been recorded from the oldest systems to the newest systems.

Mechanical construction of electromagnetic valves in automotive
Sušovský, Martin ; Novák, Petr (referee) ; Strecker, Zbyněk (advisor)
The bachelor thesis brings complex view at electromagnetic valves used in automotive. Providing closer information about its function in important parts of car. This study is mostly focused on usage of the electromagnetic valves in an injection systems, like high pressure common-rail system used in diesel engine from BOSH. Furthermore, in main part of the study, technical solutions, that lead to reduced response time, which results to improved performance of the valves, are investigated.

Tool for SQL Injection Vulnerability Detection
Kutypa, Matouš ; Samek, Jan (referee) ; Barabas, Maroš (advisor)
The Bachelor thesis is focused on the issue of SQL injection vulnerabilities. The thesis presents commonly used procedures in the attacks against information systems and are also discussed possibilities of defense including the correct ways of input validation. The theoretical part contains the essential foundation of what should the penetration tester know, to be able to examine the inputs of application for SQL injection vulnerability. The thesis also describes analysis, design and implementation of specialized tool for Web application vulnerability detection. The implemented tool was tested and compared with other existing tools. Within the thesis has been also implemented a Web application, which demonstrates many different variants of SQL injection vulnerable inputs.
