Proposal nozzle for measuring the air quantity of an internal combustion engine
Esterka, Ondřej ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
In this bachelor‘s thesis are mentioned emission standards, which apply to passenger cars, and the mixture-control system. There is also a research of volumetric and sectional flowmeters, suitable for measuring the flow volume of the air, including the principle of measuring the volumetric or mass flow. After that follows engineering design of Venturi tube for measuring the flow of the air through the chosen combustion engine. The design is based on the appropriate standard. There is also involved a welded assembly drawing of the Venturi tube, and a description, how to use the tube in a test room.

Technical standards for quality.
Nováková, Veronika ; Koška, Petr (referee) ; Fiala, Alois (advisor)
This thesis deals with the question of whether the technical standards have an impact on quality. We understand quality as a degree of compliance of requirements of a set of inherent features. Inherent feature means its own internal character of the object, whose quality is dealt. Quality and standards passed a long development, both from a point of law, as well as history, which began as early as in the old Mesopotamia by reference in Chammurapi Code. Since then, the quality changed its definition for several times, but the meaning of quality remains the same. It is necessary to mention the initiator of the quality who contributed by their work to its development, such as Prof. RNDr. František Egermayer, DrSc., who was the most significant initiator of modern understanding of quality in our country, then it is Dr. Joseph M. Juran, renowned author and "father" of modern quality management, also we must not forget William Edwards Deming, an American statesman and professor who is the most known of his work in Japan, and not least, world-famous personality Agnes Waddell, and other prominent personalities in this field. Today, quality control and normalizing ensure the main government authorities, such as Ministry of Industry and Trade of CR, which also ensures the management of other government bodies (ÚNMZ, ČMI, ČIA, see Chapter 6). The very Ministry of Industry and Trade may encharge a corporate entity to creation assurance and issuing Czech technical standards, their amendments and repeal. This assignment is non-transferable. As long as this assignment is valid, no other corporate entity must be encharged for this activity. There is no legal claim for this assignment. The costs of the creation of the Czech technical standards are covered by a person who requires processing. The costs of the creation of standards, notably the Czech technical standards transposing European standards, prepared pursuant to the request of the ministries or other central government departments and the costs associated with membership in international and European standardization organizations are paid by the State. In creation and issuing the Czech technical standards, their changes and cancellation must be provided the conditions laid down in the decision to assignment, as set out in Chapter 3.

Statistical methods in quality management system.
Vyškovský, Jaroslav ; Toul, Jiří (referee) ; Fiala, Alois (advisor)
Statistical methods in quality management system are strong tools, which helps us to make right resolutions in area of quality management, or in other possible areas, such as process control, or in assessing of specific parameters in company. In these respects we are using various norms, manuals and publications such as ČSN EN ISO 9001, ČSN EN ISO 9004 a ČSN ISO/TR 10017. In the beginning part of work we are gradually dealing with basic phraseology from area of statistical methods, next we continues with management and with process, SPC, description of basic statistical methods and in the end by data. Goal of this work is literature exploration of facts and own conclusion connected with predict of progress in these area.

Wind action on high-rise buildings
Damek, Marek ; Eliáš, Jan (referee) ; Nevařil, Aleš (advisor)
This thesis is focusing on comparison two approaches wind actions on high rise buildings. Determinist approach will consider by norm ČSN EN 1991-1-4. Stochastic approach by real wind speeds and synthetic generate wind speeds. Wind as a random value, variable on time and height. Model of water tower will use for the comparison.

Information Centre
Kovář, Jindřich ; Štrba,, Michal (referee) ; Barnat, Jan (advisor)
This bachelor thesis is concerned with the static project and the consideration of the carrier steel construction of the information centre that means the two-storeyed building with the 24 x 24m extent. The project is solved by two options. In both cases, the steel basis with components united by articulated joints is concerned. These are pillars, supporting joists and ceiling beams that are composited with a concrete desk so that they ensure the position stability in a horizontal direction. The both options differ from each other by the position stability method in a vertical direction. In the first case, the vertical clamps avoid the deformation. In the second case, two frame constructions are designed for both yawing directions. The result was the choice of the first method that is discussed in a more detailed way further.

Setting norms of consumption in the procurement operations department.
Millerová, Denisa ; Svobodová, Hana (advisor) ; Mejdrech, Vlastimil (referee)
The diploma thesis focuses on the problematics of setting the number of employees in the selected department (team) in a specific company. With respect to the severity of impact of this decision, the diploma thesis choses a sophisticated tool, norms of work consumption. To simplify their utilization a model is created to specify the number of employees. The basis for construction of the model is summarized in the theoretical-methodological part. Practical part of the diploma thesis presents the company, the department and the team and it defines preformed processes. Furthermore, it calculates (determines) individual elements needed for building the required model, namely the time normatives (norms) of the activities, probabilities of occurrence of certain activities and usable time fund of an employee. Lastly, the created model is tested by using real data from the last period and consequent recommendations are presented.
