Electronically reconfigurable frequency filters
Gajdoš, Adam ; Langhammer, Lukáš (referee) ; Jeřábek, Jan (advisor)
The aim of the thesis was design of reconnection-less and electronically reconfigurable filters of SISO type with non-traditional active elements. Adjustability of bandwidth or quality factor is also required. First part of the thesis deals with theoretical analysis of filters, their operation modes and design of frequency filters using Signal-flow graph method aswell. Last but not least, electronical reconfiguration of transfer function and parasitic analysis was discussed. Another part describes active elements used in the practical part of thesis. Behaviors and design of active elements using existing circuits (e.g. UCC,EL2082) are described and their transformation into the Signal-flow graph form too. In the practical part five reconnection-less and reconfigurable filters of SISO type was designed using SNAP program. Simulations were done using Orcad program with ideal and real simulation models of active elements. Last part deals with filter design in EAGLE and experimental measurement.

An Implementation of CellMatrix in FPGA
Martinák, Jan ; Bidlo, Michal (referee) ; Sekanina, Lukáš (advisor)
Reconfigurable hardware architecture represents a modern trend in development of the new curcuits. Rising demands on such architecture lead in efforts to create curcuit, that is able to reconfigure itself in parallel and locally. One of such technologies is the Cell Matrix which is based on principles of cellular automata. The purpose of this thesis is to inform the reader about Cell Matrix architecture and to show its advantages, functions and potentialities by implementation in FPGA on FITkit development kit.

Optimalization of Power Electric Engineering Processes by Genetic Algorithms
Paar, Martin ; Hradílek, Zdeněk (referee) ; Skala, Petr (referee) ; Toman, Petr (advisor)
Current trends in regulation of electricity supply continuity in the power engineering industry includes introduction of systems and customers standards. The electricity market liberalization in the European Union is speeded up the process furthermore. Companies included in the distribution network bussiness therefore began to be interested more in the evaluation of risks associated with the aplication of these standards. The aim of the thesis is to minimize the expenses caused by power losses of the distribution network by means of distribution network reconfiguration depending on the standard selection. For the minimization two of the Genetic algorithms was selected. As an criterion the overall expenses caused by power losses and the expenses caused by an electricity shortage. Furthermore the influence of the inclusion of the power loss to the calculation on the operation costs for given regulation standards. Two contemporary standards - finish and portugues - are considered together with three experimental standards. The aim of including experimental standards is to complete the regulation standards with parameters uncovered in the portuguese and finish standard. The results described in the thesis can be used in the distribution network optimization process from the point of reliability and operational costs.

Using of SD Memory Card for FITkit Platform
Gazda, Martin ; Slaný, Karel (referee) ; Vašíček, Zdeněk (advisor)
Reconfigurable hardware architectures represent a modern trend in development of new circuits. A lot of embedded systems is used as mobile devices with high demands on data capacity and power consumption of peripheral devices. This demands are suited with FLASH based memory, like SecureDigital memory card. This bachelors thesis deals with the problem of usage of this memory card on FITkit development platform.

Emergent urban strategies: rules of city reconfiguration
Buš, Peter
A city as a complex phenomenon and an entirety of events, its communication flows (information and data telecommunication networks and their access points), energy, goods and materials distribution and movement of users themselves and their spatial interactions with the environment nowadays no doubt has been creating new conditions and demands on the city's spatial organization, infrastructure, its growth and its thickening. Urban space today is an aggregate of complex dynamic processes which contribute to its configuration and mutually influence each other. Thus, urban environment shows emergent qualities and contains multi-layer scenarios of its own development and reconfiguration in time. This stratification is impossible to be comprehended by a linear model of a single predicted concept (top-down strategy). Architects and urban planners may, however, cover these specifics by a prediction of space development with a multi-layer result that would take into account the requirements of users at the lower level (bottom-up strategy). The aim of the research is therefore a spatial simulation of environment development, which would simulate its complexity, growth and reconfiguration. This spatial simulation would serve as a decision-making tool for architects when applying various scenarios of environment development and thereby it would create a basis for spatial planning decisions in subsequent stages of zoning proceedings. The final result of this research shall be a visualized algorithm in a model of spatial environment reconfiguration that could be serviceable also in the internet environment. This result implemented in a software tool can also serve as a creative platform for designing urban structure based on simple rules of a lower level that would, however, consequently simulate the complex urban entirety.
