To Dvur Kralove by train - Transfer Terminal in Dvur Kralove nad Labem
Hudečková, Kristína ; Růžička, Tomáš (referee) ; Ponešová, Barbora (advisor)
The terminal represents joining two things – an internal and an external – a city and a surroundings. The intetion of my bachelor thesis is to connect fluently a main hiking trail from a center of city with a bus service and train transport. To make this connection as natural as possible, the proposal of terminal is based on a mass concentration in a point of joint and gradual diffusion towards the the city and the surroundings. The terminal is designed as a longitudinal structure with a one communication in the middle of the layout. The space of terminal is defined by twenty steel frames arranged one behind the other in the direction of the axis of connection between train track and hiking trail from the center of the city. The steel frame becomes the dominant element of the terminal. Different closing of sections between particular frames creates spaces of different characters and a different rate of permeability.

Static verification and variant design of roof structure of winter sport stadium in Jihlava city
Růžička, Tomáš ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
Object of this master thesis is the static verification and variant desing of roof structure of winter sport stadium in Jihlava city. The ground plan dimensions are 60 x 84 m The current structure is composite of truss main girders with parabolic lower chords, and purlins. Axial distances of main girders are 12m. Concrete columns are a support to main girders. The variant desing of roof uses truss girders and truss purlins. They are supported on existing concrete columns. All load bearing members of existing and new design structure have been evaluated according to actual normative rules. The static assessment of the existing structure is not satisfied from viewpoint of ultimate and serviceability limit states (in some elements). The static assessment of the new structure is satisfied from the viewpoint of both limit states.

Marketing analysis of a selected company
Růžička, Tomáš ; Maitah, Mansoor (advisor) ; Kuzmenko, Elena (referee)
This bachelor thesis is focused on marketing situational analysis, its characteristics and individual steps presented on the energy company named Pražská plynárenská, a.s.. The aim is to show the importance of both internal and external environment of the company, to observe the market dynamism where the company is operating in and to identify the influences that affect the company.
The first part of this thesis describes the characteristics of marketing in general terms, the procedure of marketing situational analysis, the process of defining the right strategy, and determines the aspects of marketing that are specific in the energy industry.
The second part of the thesis is already concerned with marketing situational analysis achieved through the elaboration of each appropriate analysis suitable for the given environment of the company. The main goal of this thesis is to present and show the process of marketing situational analysis on Pražská plynárenská, a.s., by using analyses of the internal and external environment such as Marketing mix analysis, PEST analysis, Porter´s five forces model analysis and SWOT analysis.

Light Propagation Volumes
Růžička, Tomáš ; Tóth, Michal (referee) ; Milet, Tomáš (advisor)
The aim of master thesis is to describe different calculation of global illumination methods including Light Propagation Volumes. All three steps of LPV calculation are widely described: injection, propagation and rendering. It is also proposed several custom extensions improving graphics quality of this method. Two parts of design and implementation are focused on scene description, rendering system, shadow rendering, implementation of LPV method and proposed extensions. As conclusion, measurement and several images of application are presented, followed by comparison in environment with diffenent parameters, thesis summary with evaluation of achieved results and suggestions of further improvements.

Lightmap Generation Tool
Růžička, Tomáš ; Pečiva, Jan (referee) ; Polok, Lukáš (advisor)
This bachelor's thesis deals the design and implementation of a Lightmap Generation Tool. The aim of this thesis is to describe and demonstrate all steps which are necessary for lightmap creation, specifically unwrapping 3D object geometry process and consequently shading it by the ray-tracing method. The scene system and the used engine are also described in this thesis. This work is concluded by a several experiments, along with image documentation, followed by the possibilities of the future work.

HW and SW for Ethernet-to-IEEE802.15.4 bridge
Růžička, Tomáš ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
The present work includes theoretical information about network protocols, Ethernet (TCP/IP) and IEEE 802.15.4.Work also includes design of the converter realiyed using the development kit RCM 3365 from the Rabbit Semiconductor company. The converter works with the UDP, which can be converted to packets of wireless standard, or from a wireless packet can create a UDP packet. The wireless part was replaced with a serial interface RS-232, after which the packets travel in wireless standard IEEE 802.15.4. To create and monitor data on the Ethernet and RS-232 three external programs are used.

Thick-film amperometric sensor array
Růžička, Tomáš ; Prášek, Jan (referee) ; Adámek, Martin (advisor)
Supposed work deals with proposal and construction of thick-film amperometric sensor array. The reason of this proposal of sensor array is multiple increase of speed, increase of accuracy and enlargement of possibilities of measuring against current optical system. In theoretic part there is described method of seriography and electrochemical analytic method for determination of chemical elements in the solution. Practical part is composed of proposal of topology of electrochemical sensor electrodes, their comparison according to characteristics and subsequently of the proposal of sensor array. For testing of function of sensor array measuring by method of cyclical voltametry was done with the help of default electrochemical oxidative-reducing pair of potassium ferro-ferricyanide.

Influence of Al ionts in nickel hydroxide on behaviour of electrodes
Růžička, Tomáš ; Vrbický, Jiří (referee) ; Sedlaříková, Marie (advisor)
This master's thesis is concerned with the influence of aluminate ions added in various concentrations into the structure of nicel hydroxide that creates Ni-Cd accumulators positive electrode active mass basis nowadays. Nicel hydroxide occurs in two basic modifications ? and ß. Nowadays used ß modification reaches low capacity in comparison with ? modification. The disadvantage of ? modification is its instability and gradual degradation to ß modification. The aim of this diploma paper is to select the optimal amount of aluminate additives into the structure of nicel hydroxide with regard to electrochemical efficiency, stability, and degradation degree of the accumulated layer.
