Monitoring of changes of drinking water quality during accumulation and distribution
Vaňková, Jitka ; Dolejš, Petr (referee) ; Mega, Jaroslav (advisor)
Theoretical part of the diploma thesis purveys information on drinking water and quality requirements, changes of drinking water quality during distribution and accumulation caused by disinfection, chemical processes, corrosion of constructional materials, incrusting solids, biofilms, nitrification of ammonia nitrogen, sediments in pipelines, elution of harmful matter. Attention was given to drinking water quality indicators which are associated with changes in drinking water distribution systems. In experimental part are studied changes of drinking water quality during distribution on the basis of selected drinking water quality indicators. There is specifically chemical oxygen demand, concentration of iron, manganese, ammonia ions, nitrites, nitrates, chloroform and chlorine. For periodical monitoring were selected suitable locality within the framework of Brno distribution system; for illustration were taken water samples from distribution systems of drinking water treatment plants Švařec, Vír, Štítary and Mostiště. For selected methods of analytical determination of above mentioned drinking water quality indicators are presented their characteristics. Obtained information on drinking water quality is mentioned in tabular and graphical form.

Geochemical study of the lacustrine deposits of the extinct Komořany Lake
Valentová, Daniela ; Martínek, Karel (advisor) ; Beneš, Jaromír (referee)
Komořany Lake, regarded as one of the most important sites of the Czechoslovak Quaternary, was situated at the southern foot of the Krušné hory Mountains, northwest from the Starý Most town, between the villages of Souš, Komořany, Ervěnice, Dřínov, Albrechtice, Černice and Dolní Jiřetín. Due to its size, Komořany Lake belonged to the largest bodies of water in the Czechoslovak Republic (25 km2 ) and due to the quantity of organogenic sediments get into the focus of paleoecologists. Gyttji sediments which occupy comparatively thick position in the lake infilling, formed a continuous record from the Last Glacial period to the Subatlantic period and up to now have been processed mainly from the paleoecological point of view. In this work the organogenic sediments are studied from the sedimentary record using modern geochemical methods (TOC/TN and d13C) for the first time in Komořany Lake history. The work was based on profiles (PK-1-C, PK-1-Ch, PK-1-I and PK-1-W) which were taken between 1977-1983 before a complete exploitation of Komořany Lake sediments as a result of coal mining in the Most Basin in the 1980's.

Risk analysis of implementation IS innovation in international company
Dušek, Michal ; Basl, Josef (advisor) ; Fortinová, Jana (referee)
The thesis focuses on risk analysis in implementation of IT innovations in selected international company. The main objective is to analyze the specific project dealing with the implementation of IS innovation. Chosen methods for analysis are TOC Thinking Process diagrams, used for the preparation of causal trees, which serve as the basis for the project risks identification in combination with SWOT method and Why/Why diagram. Together with ongoing consultations with interested parties, the list of project risks is complied, which is the main contribution of this thesis. The list of risks is specific for the organization and it is possible to reuse it with changes for other projects. In conclusion are mentioned recommendations for each risk, which were evaluated as the most serious within the project.

Application of Critical Chain in IS/ICT Project Management in an IT Company
Šlejharová, Daniela ; Chlapek, Dušan (advisor) ; Vedral, Ladislav (referee)
This thesis deals with application of Critical Chain in IT/ICT Project management in an international IT company. Beginning with a definition of Theory of Constraints and Critical Chain from a theoretical point of view the thesis provides knowledge base for practical implementation of Critical Chain. The thesis proceeds with selection and division of various IT/ICT projects types providing their evaluation according to their usability with CCPM (Critical Chain Project Management). The thesis also contains research and overview of available resources dealing with application of Critical Chain in IT projects management. This research is presented in a form of case studies and also concluded as a summary of both achieved successes and critical success factors that should be taken into account when implementing CCPM. Based on the knowledge acquired from the previous chapters a formal step-by-step procedure defining how to proceed with CCPM in a project was defined. This procedure will be applied in a real project management as a part of this diploma thesis. The thesis also presents analysis of currently used methodology and approaches to project management in the company and using the procedure created in the previous part the methodology is extended by relevant parts of CCPM. These approaches and methodology are formalized in a Methodical Pattern for IS Development (FI) -- CCPM and this pattern is then used for application of CCPM in a software development project. The project is prepared, planned and controlled according to principles of Critical Chain. The thesis captures this process step-by-step including monitoring of the project and its buffers. For evaluation of the Critical Chain implementation in a software development project a set of criteria was developed and used for assessment. Also every member of the given project team was sent a questionnaire to provide feedback. Originally planned comparison of the CCPM project with a project managed by currently used approaches could not, unfortunately, be carried out due to lack of data and their sensitivity. Considering the scope of this thesis, the application of CCPM in a real project represents verification of validity of the Methodical Pattern for IS Development (FI) -- CCPM and the contribution is also in creation of criteria and verification of their usability for evaluation of projects and potential comparison of two or more projects. Based on the practical application of Critical Chain in a real project, suggestions and recommendation for adjustments to current methodology and also further work with CCPM in the company were provided.
