Deposition of magnetic nanostructures using EBID and optimalization of their chemical composition and morphology
Vyroubal, Ondřej ; Kolíbalová, Eva (referee) ; Kolíbal, Miroslav (advisor)
This master's thesis deals with deposition of cobalt nanostructures using Electron Beam Induced Depositon (EBID). The thesis firstly describes theoretical background regarding EBID. In the following experimental part, the deposition process is optimized via analysis of exposition parameters and their influence on the final shape of nanostructures. These are analyzed via Atomic Force Microscopy (AFM). Optimized exposure parameters are then applied to the deposition of functional 3-dimensional nanostrucutres. In particular, the deposition of cobalt spheres. The elemental composition is analyzed by the means of element composition using Energy-dispersive X-ray Spectroscopy (EDX) and the nanostructures of desired morphologies are studied with Magnetic Force Microscopy (MFM) and Magneto-Optical Kerr Microscope).

Trading on Internet Auctions
Obůrková, Markéta ; Sedláček, Jiří (advisor) ; Slaba, Jiří (referee)
Diploma thesis entitled Trading on Internet Auctions deals with the analysis and comparison of important international and Czech internet auctions. Under examination are not only important auctions in terms of number of users, but also those that surpass other interesting business solutions and innovative thinking. The diploma thesis is divided into three chapters. The first chapter, entitled Establishment and Development of e-commerce describes the most important events and milestones for the development of e-commerce and the subsequent emergence of online auctions. The second chapter is specifically devoted to the analysis and comparison of foreign auction sites. The third chapter focused attention on the Czech auction sites, including the legal aspects that are related to trading on internet auctions. The whole thesis ends by conclusion and evaluation of reaching the given object.
