Systems for remote measurement in power engineering
Hudec, Lukáš ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
The work deals with the measurement and management in power. Provides an introduction to the problems of remote meter reading, management, and describes the current situation in the field of modern technologies Smart metering and Smart grids. It also analyzed the issue of collection of networks and data collection from a large number of meters over a wide area. For the purpose of data transmission are described GPRS, PLC, DSL, ... Further, there are given options to streamline communication. This area is used hierarchical aggregation. Using k-means algorithm is a program designed to calculate the number of concentrators and their location in the group of meters. The finished program is written in Java. It has a graphical interface and shows how the calculation is conducted. To verify the results of the optimization program is given simulation model in OPNET Modeler tool. Audited results are described in the conclusion and can deduce that using the optimization program is to streamline communications.

Electricity Meters Utilization for Advanced Monitoring and Control of the Power Distribution Systems
Bernát, Jan ; Pithart, Jan (referee) ; Drápela, Jiří (advisor)
This thesis deals with a research of static meters manufactured nowadays usable in systems of smart metering. Static meters and their functions are described in terms of their internal organization, metrology and wiring. Emphasis is given to the description of new functions (detailed measuring, calendar, disconnector, communications etc.) which could not be used with induction meters and to requirements for measuring, for expenditure control, for safety of meters and for the concept description of smart grids. In a practical part of the thesis particular systems of smart metering will be described – AMR, AMM, AMI and their advantages and benefits during their deployment. The thesis includes also a catalogue of meters usable for smart metering, which is based on available information from particular producers. The final part of this thesis gives information about a pilot project of ČEZ company and about another possible functions of smart meters which could be of use in the future.

Recurrent Neural Networks for Speech Recognition
Nováčik, Tomáš ; Karafiát, Martin (referee) ; Veselý, Karel (advisor)
This master thesis deals with the implementation of various types of recurrent neural networks via programming language lua using torch library. It focuses on finding optimal strategy for training recurrent neural networks and also tries to minimize the duration of the training. Furthermore various types of regularization techniques are investigated and implemented into the recurrent neural network architecture. Implemented recurrent neural networks are compared on the speech recognition task using AMI dataset, where they model the acustic information. Their performance is also compared to standard feedforward neural network. Best results are achieved using BLSTM architecture. The recurrent neural network are also trained via CTC objective function on the TIMIT dataset. Best result is again achieved using BLSTM architecture.

Montessori pedagogy in the Czech education
Havlíková, Renata ; Hanková, Zdeňka (advisor) ; Richterová, Magdalena (referee)
The thesis processes the use of Montessori pedagogy in the Czech environment. The introductory chapters of this thesis describe the life and work of Marie Montessori, the fundamental anthropological thoughts and principles, and the development of Montessori approach. The thesis maps out by descriptive method the current institutions and primary schools which operates in the Czech environment. The following chapters contain case studies of two Montessori primary schools in Prague. The results of this thesis show that the approach of Marie Montessori is not just a rigid conception, but that it is still capable of development in the living process in school practice.

Innovation of information systems in enterprises, particularly in the utility market segment
Maloš, Martin ; Žid, Norbert (advisor) ; Tůma, Jiří (referee) ; Hübner, Miroslav (referee)
This thesis addresses the innovation of information systems in enterprises, particularly in the utility market segment. The thesis starts with a definition of utilities, a market segment containing companies involved in generation, transmission, distribution and retail of energy services as well as other companies providing related networked services. The aims of this thesis are both theoretical and practical. The theoretical part offers a new theory for IS innovations for the selected segment and for the relation between the innovation and the architectures of IS. In the practical part, the author identifies current challenges and opportunities in the selected market segment and offers scenarios and visions for future development. The first part of the thesis maps out the general innovation theories in the context of the selected topic. The second part introduces a new innovation theory based on an analysis of the specific conditions in the utility market segment. The next section focuses on the topic of IS architecture and its ability for tracking and managing the changes of the IS during the innovation process. The following part relays designs for specific architecture models supporting the current innovation trends in the utility market. The final part of the thesis summarizes particular business recommendations for innovation procedures in utilities, identifies innovation opportunities, and inspires visions for the future development of the market. The opportunities are related to a new way of understanding the role of IS in utility companies. IS provides a portfolio of information services to support the customer oriented business services, advanced services with added value and tailor made services for specific customer groups.
