Design of gated weir on the Želivka river
Staněk, Tomáš ; Roth, Tomáš (referee) ; Julínek, Tomáš (advisor)
The purpose of the diploma thesis „Design of a movable weir on the Želivka river" is a design of the reconstruction of a fixed weir in Soutice village on the river Želivka at km 1,639. The first part of the thesis deals with the localization of the area of interest and a description of all documents needed for the weir design. The first part also includes a short search of the considered structures, the findings of which are further applied in the design of a movable weir structure. Furthermore, the work continues by determining the design flow and selecting a suitable structure of the fixed weir substructure and movable closure, which is fitted to the substructure. Based on the selected types of structures, hydrotechnical calculations are performed, which also include a partial assessment of the weir stability. The thesis ends with a technical description of the proposed objects and a final evaluation of the determined achievements of the work. Part of the study is a drawing part documenting designed objects.

The Proposal for Improvement of the Work Motivation
Gřešek, Roman ; Steyer, Marek (referee) ; Pokorný, Jiří (advisor)
The aim of this thesis is to propose ways for improving work motivation in the company operating in field of financial services. In the introduction there are discussed theoretical knowledge concerning the motivation, stimulation, handling, motivation of individuals and others. There are mentioned world´s renowned authors of motivational theories, their specific theories of motivation, recommendations and strategies in motivation of managers. In the context of the work there are mentioned characteristics of the company, questionnaire survey and analysis of contemporary status in the company. At the end there are brought up problematical areas and proposed recommendations and ways to improve current situation in the company. This thesis was made for being used as a supportive material, which contains basic information that allow orientation in problems of work motivation and increase of work efficiency.

Rig for Testing Suspension Components
Nedoma, David ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
Development of car suspensions needs optimalisation of comfort, durability over external conditions, reduction of un-sprung mass, car handling. This requirements often need contradictory solutions and during solving it is necessary to take compromises. Verification of durability of car suspension is better while developing the whole car. Therefore, many solutions of car suspension test rigs are created. This thesis brings summary of existing solutions and their construction. This thesis brings its own solution of the suspended test equipment, strength calculations of main components. You can find here procedure of testing components on this test rig as well. Written ideas for future development of this rig are mentioned in last chapter

Influence of Aerodynamics on Vehicle Handling Performance
Hejtmánek, Petr ; Kaplan, Zdeněk (referee) ; Dundálek, Radim (referee) ; Píštěk, Václav (advisor)
The main aim of this dissertation was to develop a computational tool capable of evaluating the influence of aerodynamics on the handling of a vehicle. The methodology it uses is based on the simulation of driving manoeuvres with a single-track model of a vehicle, which was composed with an emphasis on minimizing the amount of necessary input parameters. This simple model, which allows the assessment of the influence of aerodynamics on vehicle dynamic and static driveability, therefore doesn’t require large amount of input data, which makes the acquirement of relevant values easier. The computational model was validated by extensive measurements of two driving manoeuvres defined by ISO norms (step steer input and steady state cornering). As a consequence of unsatisfactory initial validation results, the differences between measurements and simulations were analysed, which led to gradual enhancements of the model with additional inputs to achieve better accuracy of simulations. The final part of the thesis deals with the comparison of influences of individual aerodynamic parameters on vehicle handling and the assessment of overall significance of aerodynamics compared to other factors which were taken into account (tires, mass properties, steering etc.). This thesis was realized in close cooperation with Škoda-Auto.

Design of a weir structure with movable locking elements
Staněk, Tomáš ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The aim of this Bachelor thesis is the design of the movable barrier structure on the site of the existing fixed weir in the city district of Brno - Husovice on the Svitava River in km 7,820. The first half of the thesis deals with theoretical aspects concerning the design and utilization of weir structures. In the second half of the thesis, theoretical knowledge is applied to practical design of the moving weir structure. First of all, the locality of interest including adjacent objects is positioned and described. Subsequently, a critical evaluation of the scope and quality of input materials is performed. The following is the selection of the appropriate type of substructure construction and movable valve. Based on the chosen type of construction, hydrotechnical calculations are performed, which include partial assessment of weir stability. The thesis also includes drawings and summary description of the designed structure.

The Phenomenology of Touch and Desire
Vojtěšková, Jitka ; Hanzlová, Alžběta (referee) ; Mikyta, Svätopluk (advisor)
Still life arise from interactions related to a particular situation, location and experience. They are composed of objects that are located on a given place, of my own and borrowed or donated by my "partners". Reflect the time memory. They are a physical reminder of the experience. Still Life is manipulated, staged, composed of various artifacts that are symbolic bearer of facts that preceded them, Images may affect the perception of emotions associated with the concept of beauty, transience, decay, evoking a feeling of emptiness, to reflect the time - an irreversible momentum. Photos show a banal, everyday objects, often so obvious and neglected, What remains for us ... What remains ... What goes around ... What is gone ... Similar scenarios acquire different meanings, finding what is already absent,

Vehicle data analysis
Starý, Přemysl ; Porteš, Petr (referee) ; Zháňal, Lubor (advisor)
The diploma thesis deals with a data analysis of the Formula Student race car. An attention is given for both, vehicle and driver. Processes of braking, turning and balance of car are analysed. Special attention is given to the dampers positions while driving and their settings. Dampers velocity histograms and ride frequencies graph are put together. Algorithms in MATLAB are suggested to reduce requested time for analysis. Scripts for displaying important channels are made. Analyzed data are used to create events which accelerate orientation in record and tell the most important information.
