Aspects of Optimality and Balance Evaluation of Corporate IS
Neuwirth, Bernard ; Koch, Miloš (advisor)
This doctoral thesis deals with the aspects of evaluation of balance and optimality of corporate information systems. The initiative for this specialization was given by the increasing importance that is being laid on the perception of information systems from the point of view of a business company. More and more resources are being invested in the domain of information systems, but afterwards, it is not always ascertained that the information system is such a system, one could characterize as balanced and optimal for the company today as well as in the future. Often this is because there does not exist for the company an available and easily applicable methodic how to evaluate the system. As one of the main starting points of this doctoral thesis I have chosen the methodic HOS8 that was published 5 years ago on our faculty. The newly proposed methodic HOS2009 is trying to clear up the weak points of the original HOS8 methodic that were discovered during its practical use. This is done mainly by using the information feedback from the applicants of the methodic. Within the scope of this thesis the factors influencing the level of the particular areas of the system and the influence of these areas on its general balance are being examined. With regard to the evaluation of the balance and optimality of the information system, in this thesis the problematic of determination of a balanced and optimal state of information system for a company nowadays as well in the future are being examined. As a part of the methods output the thesis presents also charts representing the general state of the system, the imbalance of the particular parts of the IS and the relationship between the areas of hardware and software. Based on the evaluation of the current state and its comparison to the balanced optimal state for the present day as well for the future, the new possible directions and strategies of further development of the IS in the company are being proposed. I see the best exploitation of the methodic HOS2009 in the company in the support of managerial decisions with impact on: the discovery of potentially problems within the scope of IS of the company, the design of a possible course of development useful for their solution, but also the usage of the methodic as a simple control mechanism.

Formation of the Concept of energy self-sufficient of residential buildings
Hlavsa, Tomáš ; Horák, Petr (referee) ; Chlup, Jan (referee) ; Meixner, Miloslav (advisor)
Creating the concept of buildings is the primary task of architects, designers in the field of architecture and engineering. Although the basic requirements remain the same across time , possibilities of their solution are constantly evolving and changing. In addition, with the increasing globalization, in context of the housing and the architecture is expected new requirements go beyond the horizons of the interests of bouth investor and designer. Global view of each project and the evaluation of its traces left in our environment and society, although is much discussed but rarely taken into account or even just considered. In this context, we are witnessing the development of new trends of the concepts of buildings, consisting in the use of natural materials, in reducing the environmental burden of a surroundings, in reducing energy demands, or even in an effort to achieve energy independence thus trends, whose common denominator is sustainable construction, hence sustainable development in general. Feasibility of the creation of the concept of energy self-sufficient building doesn´t consist only in the precise solution of the assigned task from the perspective of the designer or investor, but also in finding such a solution which, even with using new trends and principles, will not go against the initial idea itself. The present instrument processed and presented in this dissertation has the ambition to move global view of the project into the perspective of a particular individual design process and in small way contribute to the creation of better projects from the perspective of sustainable development The term of energy self-sufficient buildings are not clearly defined. To work with them it was necessary to determine their basic definition that describes their diverse conceptual variations and allows precisely define the solution area. To correctly select the optimal solution in terms of sustainable development is necessary the assessment and mutual comparison since the beginning. As a basic tool for this assessment was used and partially modified SBTool, which is built on three basic pillars of sustainable development - SOCIAL - ENVIRONMENTAL - ECONOMIC. SBTool tries to determine the degree of left traces of the approach from the perspectives of these three aspects and evaluate the effectiveness of the selected solution. This tool allow to compare the different concepts for the same project among themselves, their parts but also various projects among each other. All of course with regard to the development of various aspects in the time.

Infuse of specialization on structure cities, rural habitat and landscape
Štěpánek, Martin ; Urbášková, Hana (referee) ; Suchánek, Radek (referee) ; Kopáčik, Gabriel (advisor)
Specialization and concentration of human activity is a phenomenon which accompanies the development of human settlements from their very beginning. While thoroughly explored in other fields, interconnection between pecialisation, on one hand, and urbanism and architecture, on the other, has been neglected. Nevertheless, this issue is of high ignificance since it determines the settlement structure development to a large extent. If understood correctly, this underlying principle of the impact of specialisation and concentration on the settlement development offers a new insight into historical context and enables one to understand the present development.

Potential calculation of mutual information from a time series
Hubr, Ivo ; Smékal, Zdeněk (referee) ; Mekyska, Jiří (advisor)
Mutual information is one of the factors used in traffic analysis and preparation phase space. Begin of this work deal with information theory, focusing on the calculation of mutual information. To calculate this parameter has been available for many algorithms which are analyzing in this final work. Two of the algorithms (Fraser-Swinney and calculation of mutual information using adaptive XY subdivision) are applied to the input data Rössler’ attractor, as shown in the output tables and graphs. The third consideration method is the computational Dinh-Tuan-Pham algorithm. The main goal of this work is a comparison of efficiency, speed and accuracy of the calculation of these algorithms.
