VoIP and QoS
Kolmačka, Jan ; Křivánek, Vítězslav (referee) ; Kovář, Petr (advisor)
The bachelor’s thesis gives the basic information about the solution of a problem with Quality of Service in sequence with the VoIP telephony. In a few last years the VoIP technologies and basically the other multimedia applications have unbelievable grow. It is caused by a big demand internet user’s for the new interactive applications offering voice transfers and streaming video. These new habits bring quite big requests on networks from the side of QoS. That is why, it was necessary to develop new methods, which reach requested parameters of QoS in single categories. The first part discuss theoretically about protocols used in the VoIP telephony. The second part presents QoS, parameters of QoS and two basic methods for guarantee QoS. In the last part of the bachelor’s thesis is theoretically described the QoS support in Wi-Fi with the main aim on new technologies QoS reservation defined in the 802.11e. The following simulations and the results of the different settings parameters QoS are made by the powerful simulating software Opnet Modeler.

Localization of a Moving Target using a MIMO Radar System
Šulc, Martin ; Vychodil, Petr (referee) ; Škorpil, Vladislav (advisor)
The aim of this thesis is to estimate parameters of the moving target using different radar configurations. First the Doppler effect and the time delay of the received signal is examined. The investigation of these phenomenons is made for radial and non-radial movement of simple monostatic radar configuration and after that for the bistatic and multistatic MIMO configuration. The ambiguity function is presented for all these configurations. The ambiguity function is then used to estimate target parameters from the received signal. The received signal model and ambiguity function for the monostatic radar configuration is developed using Matlab software. Finally the practical use of these implementations is presented and compared.

Simulated Fault-Injection in Network Communication
Rozsíval, Michal ; Rogalewicz, Adam (referee) ; Smrčka, Aleš (advisor)
The development of network applications takes place under ideal conditions, as opposed to deploying them in a real-world environment that contains vulnerabilities such as loss, latency, or cyber-attacks. Ensuring resilience against these vulnerabilities is thus crucial. This thesis introduces the NetLoiter, which aims to enable the simulation of the required vulnerabilities and thus allow developers to treat them correctly. The NetLoiter can be used in transparent (proxy server), hidden (captures communication directly from the system kernel), or hardware versions suitable for testing embedded systems. NetLoiter supports dynamic reconfiguration using a public interface that can be used to automate the testing process. NetLoiter has been successfully integrated and used in real projects.

Sound Effect "Glitch Machine"
Cimmerman, Matej ; Mošner, Ladislav (referee) ; Černocký, Jan (advisor)
This thesis addresses software music effects and their implementation. It shows design and implementation of the Glitch Machine, which belongs to the music multieffect programs and demonstrates the simultaneous use of various music effects to process audio signals. The result is a program for Windows OS, which utilizes cooperation of various effects, namely a filter, reverb, distortion, extractor, reverz, stutter, shifter, pitch resample and gain. It allows extensive and detailed editing of an audio track and a higher extent of manipulation with sounds, than with single music effects. Other components of the program include visualisations of the waveform and frequency spectrum of audio signals and an option for loading and saving effect presets. The program was tested in tests of the performance and memory usage and also with user testing of quality and graphical interface.

Default of time in business transactions and its consequences
Kolář, Ondřej ; Patěk, Daniel (advisor) ; Oehm, Jaroslav (referee)
Delay in commercial commitments and its consequences The purpose of the thesis is to describe all the aspects of delay in commercial commitments in the law system of the Czech Republic with focus on the consequences a delay may cause. Even though the history of the respective legislation is long and uninterrupted (it basically dates back to the Austrian General Civil Code from 1811), certain cases of indistinct interpretation in every-day use of the rules may still arise and that is the reason for elaborating the research. Legislation, expert interpretation of the legislation, papers from professional journals and a number of judicatures, mostly decisions of the Supreme Court of the Czech Republic, are used to thoroughly analyse the topic. The Czech Commercial Code recognises two general kinds of delay - debtor's delay, which occurs if the debtor does not fulfil their (usually contractual) duties in time and/or properly and creditor's delay, that is initiated by the creditor if they do not accept proper fulfilment from the debtor and that supersedes the debtor's delay, if it may be in place. In case of the debtor's delay the law automatically guarantees the creditor several rights. They have the right to insist on the proper fulfilment to be delivered or they are entitled to cancel the contract, if...

Delay in the new Civil Code
Doležal, Tomáš ; Štenglová, Ivanka (advisor) ; Patěk, Daniel (referee)
The thesis which is called "Delay in the new Civil Code" analyses the general legal regulation of delay and its consequences under the current civil code and related European and Czech legislation. The thesis explains the system of the current regulation, explains the nature and meaning of delay, defines the term "delay" and partial terms "debtor's delay" and "creditor's delay" and how they relate to the term of performance of a obligation. The work further focuses on analysis of the individual consequences of debtor's delay" and "creditor's delay. The closing part of the work contains comparison of the current Czech legislation with the international regulations such as UNIDROIT Principles of International Commercial Contracts (PECL); The Principles of European Contract Law and Draft of a Common Frame of Reference (DCFR).
