Optimisation of a Voice Transmission in Communication Networks
Novák, David ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
This master’s thesis deals abou the transmission of voice in communications networks. The theoretical part describes criteria for optimizing voice, such as quality of service, type of service, level of service, service type, and mean opinion score. Next I describe the Internet Protocol, comparing IPv4 and IPv6, VoIP, including security, protocols and parameters necessary for transmission. Other part is about neural networks. There are basically described the neural network, Hopfield neural network and Kohenen neural network. The research is based on a comparison of the network without ensuring the quality of service and with ensuring quality of service. Then, there are compared two types of switches. Classical switch-controlled sequentially, and switch controlled by neural networks. The overall simulation program is implemented in Opnet Modeler. The conclusion deals with the creation of laboratory tasks in this program to compare the different systems of ensuring quality of service.

The study of polymorphism and optimization of active pharmaceutical ingredients crystallisation
Novák, David ; Ing.Ladislav Cvak, Ph.D. (referee) ; Ing.Roman Gabriel (advisor)
Active pharmaceutical ingredients (APIs) are frequently delivered to the patient in the solid-state as part of an approved dosage form (tablets, capsules, etc.). Understanding and controlling the solid-state chemistry of APIs is therefore an important aspect of the drug development process. APIs can exist in a variety of distinct solid forms, including polymorphs, solvates, hydrates, co-crystals and amorphous solids. Each form displays unique physicochemical properties that can profoundly influence the bioavailability, manufacturability, stability and other performance characteristics of the drug. Most APIs are purified and isolated by crystallisation from an appropriate solvent during the final step in synthetic process. The main objective of a crystallisation process is to produce crystals with desired properties such as particle size distribution (PSD), shape and purity. All pharmaceutical dosage forms must be produced in uniform units, and good content of uniformity is only possible when the size of the active component is carefully controlled. For on-line control of crystallisations of Quetiapine Fumarate to achieve desired PSD and no changed physicochemical purity was used the Lasentec Focus Beam Reflectance Measurement (FBRM) system.

From single feature to settlement pattern, landscape and society: a methodological approach to castellological research
Novák, David
Fortified manors are in the scope of interest from the 19th century and at present, we have solid and complex knowledge base, which can be evaluated to obtain interesting results. Most of the published papers dealing with fortified manors have undergone basic chronological and typological analysis without further interest in their spatial attributes or their relation to the hinterland. This fact and underestimation of quantitative analysis and statistics may be explained in the context of the culture-history paradigm, still prevailing in Czech archaeology. Alternatively, perhaps, it is just a result of the methodological inability of many archaeologists to deal with large data sets. As a response to this situation, the author attempts to look at fortified manors in another way - through statistical methods and using GIS. Paper is aimed to present methodology used in case study of selected region in western part of Central Bohemia as a sample.

State informations keeping methods using HTTP
Novák, David ; Pinkas, Otakar (advisor)
The mission of this batchelor thesis is to give complete view to the problems concerning usage of interactive WWW services in the internet, where the communication is runned by HTTP protocol. This protocol is stateless. It means, that no information is stored between each connection. Nowday’s interactive web applications needs state informations for their proper functionality. That’s why this thesis considers methods of storing and transmission of state informations. In the first part is HTTP protocol described with mentions to the historical development. Actual version HTTP 1.1 is mainly focused. Next part is addicted to state informations, to the definition explanation, classification and methods of storing and transmitting theese informations. Following section is concerned with communication intermediaries in HTTP protocol. It means proxy and cache servers, which saves backup coppies of data for faster reusing and transmission capacities saving. This system brings along many problems, which are discussed in context of internet activity. References to extension of HTTP protocol for carrying state informations are highlighted. This is cookies. Their security risks are being discussed and also implementation in the relation to other methods is evaluated. In context of cookies is described P3P platform concerning protection of users privacy. Practical part consists of trivial application implementing the best of methods described here from the view of security and protection of privacy. Whole work might serve to the web application builder, it helps to understand patterns and to detect appropriate security risks.
