Information System Assessment and Proposal for ICT Modification
Konečný, Tomáš ; Novák, Lukáš (referee) ; Koch, Miloš (advisor)
The bachelor thesis deals with the design of the information systém for VIVO CONECTION s.r.o., which specializes in providing internet conection and communication technologies. The company uses an information system called IKARUS, which evolves itself. Based on the analysis of the current state, I will try to find weaknesses of the information system and propose optimization for maximum efficiency. The outcome of this thesis will draft amendments of information system to achieve better efficiency.

Essays on Migration and Trade
Konečný, Tomáš ; Dušek, Libor (advisor) ; Rauch, James (referee) ; Girma, Sourafel (referee)
The unifying theme of my dissertation is access to foreign markets, be it through social networks (immigration), or independent NGO-driven initiatives (Fair Trade). In the first paper, "Immigrant Networks, Trade Creation, and Trade Diversion", I derive a simple gravity model with matching and use data on the foreign-born population located in 19 OECD-member countries to estimate the impact of immigrant links on trade. The relative impact on trade of immigrant networks declines with the GDP of source country and is generally smaller than estimates from preceding studies. The theoretical framework explicitly models forgone bilateral trade and shifts in trade flows due to immigrant links. There is some empirical evidence that immigrant networks change trade flows between countries. The net effect on total trade of a 10-percent increase in the overall immigrant stock varies between -0.12 and 1.18 percent for host countries and -6.99 and 2.58 percent for source countries in the sample. The second essay entitled "Expatriates and Trade" evaluates the contribution to bilateral trade flows of expatriates from the OECD economies living in less developed countries. Similarly to the results of the existing research that focused on immigrants moving in the opposite direction, I find that the expatriates promote trade...

Design of a Robotic Cell for Load Testing Purposes
Konečný, Tomáš ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
This thesis is focused on design of a robotic cell for load testing purposes. At the beginning the aim of work is determined by objective testing. Next part is description of a test object, current work station and the present state of work. Further is determined one variant of solutions and are selected elements of the robotic cell. The design of layout follows especially with regards to safety and is processed simplified risk analysis. The second half of the work consists of developing a driverless robot design of the measuring device. The end of thesis is price calculation.

Cooler for heat pump inverter
Trepka, Petr ; Konečný, Tomáš (referee) ; Hejčík, Jiří (advisor)
Thesis in the introductory section describes the theory of heat pumps, the principle of their functions, including components used in pumps. The thesis includes a description of the air-water heat pump indoor unit, which also includes a frequency converter. Electronic frequency converter produces waste heat that must be cooled. The most extensive part of the work therefore deals with the computational model of heat transfer in the exchanger. The output is a map of all heat pump operating points with checking cooling efficiency of the inverter. In the final part are recommended modifications of the cooler design.

Surface treatment of aluminum alloys
Petr, Jiří ; Konečný, Tomáš (referee) ; Zmrzlý, Martin (advisor)
The thesis is focused on the surface treatment used for the preparation of aluminium alloys for the adhesive bonding. The theoretical part can be divided into three chapters. The first of them deals with aluminium alloys, the second one speaks about the adhesive bonding. The surface treatment itself, especially the conversion coating issues, is discussed in the last chapter. The experimental part is focused on the optimalization of a two-step titanium and zirconium based conversion coating technology. In the first part, the aluminium alloy is analysed by the glow discharge optical emission spectroscopy. The second part of the experiment deals with the first step of the technology, acidic deoxidation. The objective was to examine the influence of the exposure time on the morphology of the alloy surface and the shear strength of adhesive joints. In the last part of the experiment, the conversion coatings are prepared and characterised by the scanning electron microscopy and energy dispersive spectroscopy.
