Thickness of sheet and hardness of welded joins
Valášek, Daniel ; IAE, Michal Loskot, IWE, (referee) ; Molliková, Eva (advisor)
Theme of this bachelor’s thesis is to determine the effect of material thickness, laser beam power and the material itself on hardness of the weld joint created by laser welding of construction steels. In addition to description of welding technology, this thesis also includes description of the undertaken experiment and its results which include photographs of microstructure from all weld joint zones and photograph evaluation.

Determination of mechanical characteristics of coatings using impulse excitation technique
Valášek, Daniel ; Řehořek, Lukáš (referee) ; Válka, Libor (advisor)
This diploma thesis deals with the determination of the Young’s modulus of coatings using the impulse excitation technique (IET). The theoretical part of the thesis describes Cold and Thermal Spray technology, theoretical foundations of the impulse excitation technique and models of composite materials. The experimental part of the thesis deals with the determination of the tensile modulus of copper coating created by Cold Spray technology. The impulse excitation technique has been used to measure fifteen samples with coating thickness ranging approximately from 0,4 to 2 mm. Results from this measurement were evaluated using five composite models to establish the Young’s modulus of the applied coating. The best results were achieved by using the composite model based on rule of mixtures (ROM).

Informing a Patient during Medical Treatment
Dufková, Pavla ; Prošková, Eva (advisor) ; Valášek, Daniel (referee)
This bachelor thesis deals with the issue of providing foreknowledge to a patient being provided with health care and nursing. The theoretical part is focused on the description of the patient's lawful right to be provided with information on his health condition in connection with health care, on written informed consent, health documentation as a file with personal information, and the obligatory confidentiality of the medical staff. In the practical part, methods of qualitative and quantitative research for data acquisition were used to obtain data to find out which information nurses provide during their practice, and whether the information corresponds to their competences. Further, the research was aimed at obtaining data on the process of signing the written informed consent, determination of nurses' theoretical knowledge, detection of possible data leak during nurse reporting, nurses' acquaintance with the rules of the obligatory confidentiality of the medical staff, and finding out if nurses are interested in providing patients with information.
