Heat recovery in Building Services
Hrabová, Kristýna ; Plášek, Josef (referee) ; Šikula, Ondřej (advisor)
This thesis deals with the optimization of sewer heat recovery. For proper design and optimization it is necessary to use three basic methods: diagnostics, heat balance calculations and modeling. In 2D software Area Calculation are simulated different types of sewer exchangers arranged in sewer pipes. Using models of software CalA and simulations will be selected optimal variant. Using software BSim, which is based on more zone numerical simulation of the energy needs of buildings in relation to indoor climate, are detected heat needs of an office building. The optimal number of sewer exchanger is designed from the identified performance heat exchangers and supplies heat for the building.

Survey and Evaluation of Existing Construction
Kozubková, Tereza ; Hrabová, Kristýna (referee) ; Cikrle, Petr (advisor)
The diploma thesis deals with the survey and evaluation of the existing structure. The theoretical part of the work is focused on the description of devices and methods used for destructive and non-destructive diagnostics of existing objects. In the practical part, a search of previous surveys and their results is processed, and an own diagnostic survey of the structure is also carried out. Based on the results of the survey, a critical element of the structure is selected and statically assessed, and then a method of statically securing the object is proposed

Risk Asessment of Construction and Demolition Waste
Repka, Matej ; Láník, Jaromír (referee) ; Hrabová, Kristýna (advisor)
Master’s thesis deals with the assessment of risks associated with construction and demolition waste. These are risks mainly related to environmental protection, safety and health protection of workers handling construction waste on the construction site, as well as technical aspects of the use of recyclates. The tools selected for this thesis to identify and analyse the risks are cause and effect analysis (Ishikawa diagram) and bow-tie type analysis. For the assessment of the identified risks, the methods selected are the risk matrix and then the Failure Mode and Effect Analysis (FMEA), which also deals with the design of measures for each problem, which aim to minimize the probability of occurrence and impact of the identified risks. Thus, the aim of the thesis is to identify, assess and analyse the risks and determine simple measures to eliminate or mitigate them.

Analysis, assessment and management of risks of manufacturing process
Ďurovcová, Júlia ; Balgová, Zuzana (referee) ; Hrabová, Kristýna (advisor)
This thesis focuses on risk management in the production process of Frentech Aerospace, s.r.o. At the beginning the thesis covers the theoretical background of risk management, quality management and safety. This knowledge has been expanded with quality and safety requirements based on international standards. For a proper measurement of the identified hazards, a perfect understanding of the evaluated system is necessary. For this reason, the method of process flow diagrams was used to provide a visual representation of the company's production process, together with a description of the individual production operations. The FTA method was selected to identify the causes of the failure conditions, which provided the basis for the final failure mode and consequence analysis. Due to the systematic approach of risk identification and assessment, the most serious process risks were selected. These are provided in the thesis with recommended preventive suggestions that lead to the minimization of the identified risks.

Analysis, assessment and management of risks of the purchasing process of the selected company
Šurík, Jakub ; Balgová, Zuzana (referee) ; Hrabová, Kristýna (advisor)
This diploma thesis is focused on the analysis of the purchasing process of a selected company. The purchasing process in the company is approached theoretically, including various definitions from the field of riskology. After establishing the objectives of the thesis, the specific purchasing process of the selected company is analyzed using BPMN diagrams to visualize it. The PESTLE method is used to analyze the environment of the company. A register of possible risks in the purchasing process of the company is written to create a risk matrix. Subsequent bow-tie analysis provides a more detailed elaboration of the risks and proposes preventive and reactive measures to reduce the mentioned risks. This is followed by a summary of the analysis results obtained and an evaluation of the benefits of the proposed measures.

Analysis, assessment and management of risks of process
Kaplan, Miloslav ; Balgová, Zuzana (referee) ; Hrabová, Kristýna (advisor)
This master’s thesis deals with risk management associated with a construction company. The main goal is to analyze possible risks, asses their magnitude, and propose measures that mitigate the overall risk. For construction companies, it is crucial to mitigate risk, especially from the point of view of safety, but attention must also be paid to the quality of contracts, their timely fulfilment, and the overall profitability of the company. The evaluation of these important attributes is processed using FMEA analysis, and one selected risk is displayed graphically using the Bow tie method. The result is the analysis of possible risks for the internal and external aspects of the company as well as for interested parties with the design of countermeasures to reduce the level of risk. The partial goal of the work is to assess whether the company complies with all legislative regulations. This is processed through the assessment of compliance with legislation.

Landfilling as one of the causes of climate change
Knopp, Lubomír ; Balgová, Zuzana (referee) ; Hrabová, Kristýna (advisor)
This thesis deals with municipal waste landfilling. The aim of the thesis was to map the current situation of municipal waste management, to present the European and Czech strategies in the field of waste management and to evaluate the risks associated with landfilling. The thesis examines all the consequences and risks of landfilling. The thesis then looks at the difference objectives and action plans of the European Union and the Czech Republic in the field of waste management. Finally, educational tools for waste prevention in the Šternberk micro-region are presented.

Risk Analysis of Sample Preparation for Transmission Electron Microscopy
Gálíková, Markéta ; Hrabová, Kristýna (referee) ; Balgová, Zuzana (advisor)
Tato diplomová práce prezentuje analýzu rizik při přípravě vzorků pro transmisní elektronovou mikrosopii. Jejím cílem je zvýšit bezpečnost práce v laboratořích, které se přípravou a nalýzou vzorků zabývají. Tato práce se zaměřuje na identifikaci potenciálních nebezpečí, hodnocení rizik a navrhuje efektivní strategie na zmírnění nebo eliminaci rizik. Práce je rozdělena na dvě hlavní části. První je teoretická, která shrnuje informace o přípravě vzorků a legislativní požadavky určené Evrpskou únií a Českou republikou. Druhá, praktická část, popisuje vypracovanou analýzu rizik. Blokový diagram, analýza příčin vad a následků i analýza příčin a následků byly použity tak, aby se zjistilo co nejvíce informací o rizicích spojených s procesem přípravy vzorků. Navíc byla navrhnuta opatření tak, aby byla zjištěná rizika eliminována nebo alespoň zmírněna. Navrhovaná opatření ke zmírnění rizik byla například: používání osobních ochranných prostředků, ergonomická opatření, revize vybavení a pokyny pro zacházení s chemickými látkami. Výsledky analýzy rizik ukazují, že po zavedení navrhovaných opatření dojde k výraznému snížení úrovně rizika, což ilustruje snížení prioritního rizikového čísla. Zjištění zdůrazňují význam začlenění analýzy rizik do procesu přípravy vzorků pro vytvoření bezpečnějšího pracovního prostředí.

Green energy: benefits and risks
Cibulková, Magda ; Balgová, Zuzana (referee) ; Hrabová, Kristýna (advisor)
This master´s thesis deals with a topic green energy. Firstly, in the theoretical part of the thesis, there are described basic types of renewable sources of energy, including their principles and their advantages and disadvantages. Secondly, in the practical part of the thesis, there are provided analyses SLEPTE and SWOT. Their aim is to provide a comprehensive overview of the benefits and risks of the green energetics. Furthermore, an Ishikawa diagram is processed. There are graphically showed causes which are leading to the transition to the green energy. Finally, there are identified and mathematically evaluated environmental risks of the green energy in a simplified form of FMEA method. In addition, there are proposed measures in order to mitigate these risks.
