Lead-acid battery formation
Hlaváč, Pavel ; Tošer, Pavel (referee) ; Vaculík, Sebastian (advisor)
This bachelor project deals with the pulse charging of lead-acid batteries and ways of formation of electrodes so that the new batteries can constantly offer high performance and efficiency for its life. The work is an attempt to compare and determine whether the formation of different charging modes will not have a major impact on the quality of a formed battery. The formation of the different modes uses both the pulse and continuous charging. Everything is tested on four manufactured articles. The production of positive electrode and formation of accumulator is processed in various chapters of my project at our workplace.

The examination of the effect of titanium dioxide on the properties of lead-acid batteries
Mlýnek, Martin ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
Despite, considerable advances in technologies for storing electrical energy, lead-acid batteries are still the most widely used these days even it was invented more than a century ago. The functionality remains the same since its invention. Today´s time puts certain pressure on improving some aspects of the functionality like, heat management, charging and discharging speed, capacity and durability etc..... This bachelor´s thesis is based on the last mentioned, Durability,. The work presents the theory of acid batteries with the history of chemical reaction, technological production processes and battery construction. It is followed by a chapter about titanium and titanium dioxide as an addition of negative active mass where all the aspects are being examined in this work.

Assessment of Market Value of the Easement on the Route of the Sewage Pipelines
Konečná, Jana ; Hlavinková, Vítězslava (referee) ; Hrubanová, Michaela (advisor)
This dissertation deals wtih a problematice of easements of real estates in Czech Republic.The main goal of the dissertation is to estimate the value of considered easement and value of the family house burdened with the easements, consider and give reasons for possible devaluation of the real estate by making the easements. In the theoretical part are defined the terms connected with the real estate business, methods of valuation of the real estates and terms from land registry. Legislation of easements, methods and proceduresof valuation of easementsand valuationof real estates with easements follows. Practical part is about valuation of easements. Municipakl authority in Vyškov reallized construction of sewers in local parts Lhota and Rychtářov. The sewers goes through lands thats why the easements are established for the land owners. The easements are provided with conrtracts. The final part of the dissertation includes the summary and comparison of easements in 2011 and 2014, example of valuation of family house in local part Rychtářov and valuation of the influence of easement on the real estate.

Enterprise's Image as an aspect of Comptetitivness Development
Chakrian, Andrei ; Velinov, Emil (advisor) ; Denisov, Igor (referee)
The purpose of this thesis is definition of influence of image of the enterprise on competitiveness, and also to carry out the analysis of current state of image of LLC Alliance Distribution Company and to develop actions on to improvement. In this thesis it to be told about development of an imageology in Russia, image definition, his contents and types is given. It is told about communication of image and competitiveness at the enterprise. As growth of value of the consumer to goods and services is result of formation of image. At the thesis there is a general characteristic of the enterprise and image of LLC Alliance Distribution Company is analyzed. Actions for improvement of image and councils for increase of competitiveness of the enterprise due to image are written.

Impact of Size Effects on Formation of Nanoparticles from Supersaturated Vapor
Levdansky, V.V. ; Smolík, Jiří ; Ždímal, Vladimír ; Moravec, Pavel
The mechanism of nanoparticle formation in condensation of a supersaturated vapor is of interest for different kinds of atmospheric phenomena and processes of nanotechnology (e.g. manufacture of nanoparticles). Homogeneous nucleation is the initial stage of nanoparticle formation. The critical cluster size is one from the main parameters in the classical nucleation theory. The value of the critical cluster size is usually found from the Kelvin equation which does not depend on the condensation coefficient. In the general case the size dependence of the condensation coefficient can influence the critical cluster size (Levdansky, 2002). The size dependence of the cohesive energy in the nanoparticle can also affect the size of the critical cluster. Below we consider the joint influence of above-mentioned size effects on the critical cluster size, the rate of nucleation and the growth rate of arising nanoparticles.

Oscillation of Interfacial Meniscus during the Formation of Bubbles
Stanovský, Petr ; Růžička, Marek
A closer look at the interphase meniscus in the model system with a transparent plate using a high-speed camera has showed that after detachment of the bubble the meniscus moves to the lower orifice rim. On that rim the meniscus oscillate dumped by increasing pressure in the space below the plate. In the description of the bubble growth at the orifice during so called waiting period accrue the equations describing the oscillatory behavior of the meniscus. Together with the nonlinear Rayleigh-Plesset equation it results in a bifurcation behavior - the volume of bubbles differ by up to 50% from the mean at certain values of the gas flow. This phenomenon has not been previously identified as the time-averaged values of bubble sizes conceal this effect.
