Springing and Damping of Truck Cabin
Kroupa, Ondřej ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
This Diploma Theses, which can be included in the field of vehicle dynamics, explores the effect of suspension and damping of truck cabs for the safe ride and comfort. As the driver spends many hours in their vehicle, comfort is the most essential criterion. That is why we seek possible improvements which are offered by the sprung cab. The research part firstly analyses the individual elements of suspension and damping. The following chapter is devoted to the systems which are used nowadays in the construction of cabin suspension. Next there is the introduction to the theoretical production of a simplified computational model as well as the presentation of the possible evaluation of the achieved results. The following practical part deals with the actual shaping of the computational model in the Adams View software, which is based on a real vehicle, and was lent at the faculty. The model is then verified and compared with the existing state and the cab mounting concepts are tested on it. The effects of cab parameters on driving comfort and safe riding were tested on it as well. The last part focuses on the forming of the special Dakar computational model, on which optimization was performed according to the findings discussed in the previous chapter. Also, the appropriate configurations to the real-life testing were designed.

Information System Assessment and Proposal of ICT Modification
Kroupa, Ondřej ; Koch, Miloš (referee) ; Novák, Lukáš (advisor)
The main goal of this bachelor thesis is to analyse the information system of the Company, which deals with the sale and distribution of breeding and food for domestic and farm animals and the subsequent proposal of changes to increase efficiency and productivity in the company. The first part of this thesis will focus on theoretical concepts related to this issue and their explanations. The next part will focus on the introduction of the company and the evaluation of the current state of the company in terms of infromational system. The last part will focus on changes that, after their implementation, would help to improve work processes in the company.

Design of military vehicles
Kroupa, Ondřej ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor thesis is focused on military vehicles and their construction. At first it is needed to divide them into categories by the valid Czech legislation. The issue of the crawler and wheel chassis is also important, as both have their advantages and disadvantages. The construction of the crawler chassis and the problematics of the construction on the basic wheel chassis components, which often differs from road vehicles, are analysed next. One of the important construction areas today are also the elements of protection, which can be passive or active. While designing the military vehicles, it is also necessary to take into account their special position within the legislation. The thesis addresses the problematics of emissions and noise rules, which is different from measures valid to road vehicles. In conclusion there is an indication of possible future development.

Documentation of sinkholes in Vilemovice locality
Kroupa, Ondřej ; Kuruc, Michal (referee) ; Vondrák, Jiří (advisor)
The main object of this bachelor thesis is area survey of locality close to Vilémovice. It was planimetric survey of field and specific locality of Vilémovice along with planimetric and altimetric survey of sinkholes. According to those surveys was made a thematical mapin scale 1:1000.For sinkholes was made detail in scale 1:500.

Digital terrain model in the area of Admas
Kroupa, Ondřej ; Kalvoda, Petr (referee) ; Hanzl, Vlastimil (advisor)
The goal of this thesis is to scan part of the complex research center AdMaS using terrestrial laser scanner, from obtained data draw up a 3D terrain model and compare the height accuracy with conventional terrestrial measurement. The thesis is focused to software, which allow processing of point clouds and prepare the 3D model. The output of this work is the 3D terrain model and two transverse profiles for vertical comparison of two measurement methods.
