Influence of changed shape and dimensions of a helical spring on its compression characteristic
Melichar, Marek ; Majer, Zdeněk (referee) ; Burša, Jiří (advisor)
The bachelor thesis deals with a change of a shape of a spring in order to facilitate its assembly in a gas boiler controller assembly. The introductory part deals with familiarization with the given issue. Then, based on the algorithm created in the bachelor thesis "Assessment of characteristic of a helical conus-shaped spring under compression" of Libor Loveček, the calculation program is adapted for calculating the existing conical spring and is further modified for other spring shapes. Accuracy of the created algorithms is verified by comparing the results with commercial computing programs. Based on the calculations, new shapes are designed, manufactured and experimentally tested. At the end of the thesis the possibility of usage of created alternative shapes is evaluated.
Are There Any Digital Curators in Czech Libraries?
Římanová, Radka ; Melichar, Marek
The development of digital repositories reveals the need for new Czech terminologies for library positions. One such job title or specialization is “digital curator”, a term which refers to a specialist responsible for digital collections. Competencies for digital curators include technical, organizational, communication, and marketing skills as well as some level of expertise in computer science as well as in information and library science. A survey of several administrators of Czech digital libraries asks how to best professionally label this group of library staff with respect to the actual activities they perform in their jobs - digital curators, administrators of digital libraries, or digital librarians? Job titles have a strong impact on higher education curricula, on the management of libraries, and also on the coordinated system of remuneration of employees at libraries, academic, and research institutions.

Turbocharger Test Stand
Melichar, Marek ; Ramík, Pavel (referee) ; Svída, David (advisor)
This master’s thesis contains information about a construction of a turbocharger test stand, which is specialized in vibrations and noise testing. In the theoretical part, there are information about parts of turbochargers and basic division of the tests, which are practiced on them. Because of a specialization in testing of noise and vibrations, there are also chapters about these themes. In the practical part of this master’s thesis, there is a description of the development of the turbocharger test stand I designed. There is also an example of the results of the modal analyses, which were used to improve the construction of the test stand. At the end of this thesis, there is a description of the software, which is used to read and process the data from measuring the components.
Combined supercharging internal combustion engines
Melichar, Marek ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
This bachelor’s thesis contains a basic division of various types of combined supercharging and a description of their functions. For the most common types of supercharging technologies there are listed specific examples of usage in the automotive industry. This thesis also contains a short overview of the history of supercharging and an analysis of ideal cycles supercharged internal combustion engines. One of the most important chapters of this thesis is thermal efficiency of supercharged engines and their comparison with naturally aspirated internal combustion engines.
