Design of algorithms for neural networks controlling a network element
Stískal, Břetislav ; Kacálek, Jan (referee) ; Škorpil, Vladislav (advisor)
This diploma thesis is devided into theoretic and practice parts. Theoretic part contains basic information about history and development of Artificial Neural Networks (ANN) from last century till present. Prove of the theoretic section is discussed in the practice part, for example learning, training each types of topology of artificial neural networks on some specifics works. Simulation of this networks and then describing results. Aim of thesis is simulation of the active networks element controlling by artificial neural networks. It means learning, training and simulation of designed neural network. This section contains algorithm of ports switching by address with Hopfield's networks, which used solution of typical Trade Salesman Problem (TSP). Next point is to sketch problems with optimalization and their solutions. Hopfield's topology is compared with Recurrent topology of neural networks (Elman's and Layer Recurrent's topology) their main differents, their advantages and disadvantages and supposed their solution of optimalization in controlling of network's switch. From thesis experience is introduced solution with controll function of ANN in active networks elements in the future.

Application of system catalogue for database management
Nečas, Jaroslav ; Pfeifer, Václav (referee) ; Kacálek, Jan (advisor)
The purpose of this project is to create a design and subsequently the web application for a database management which uses the system catalogue of the Microsoft SQL database system. The introduction deals with the principle of the relational databases and includes the list of the most widespread database systems. The next chapter of the theoretical part describes the syntax of the SQL query language, and the next chapter deals with the properties of the system catalogue which were utilized. Finally, the last of the theoretical chapters is centred on the .NET platform and its technologies – particularly the ASP.NET and the ADO.NET technologies. The former is used for creating dynamical web pages, and the latter is an object library used for the data access. The practical part of this work comprises the web application scheme on which is the final web application based. The most emphasized issues in this part are the security and the supposed program design of the web application. The final part of the work contains a description of the finished web application, especially the configuration and the functions which the application provides to a user. And finally, the whole project is briefly evaluated in the conclusion.

Application of neural networks in telecommunications
Šulák, Michal ; Koula, Ivan (referee) ; Kacálek, Jan (advisor)
This Master’s Thesis consists of description of current routing protocols and routers, basic principles of neural networks and their interpretation in connection with the use for routing in data networks and telecommunications networks. In the thesis I focused on neural networks, which use energetic functions to find solution stabled states and their use for data routing. I produced the application software to test and find suitable variables for each function. This application counts the shortest path and is able to change variables to reach the best solution of stabled state of neural network. These solutions are compared with other functions that are usually used in nowadays systems for data network routing.
