Mixed-flow submersible water pump driven by hydrostatic motor
Para, Marcel ; Ranuša, Matúš (referee) ; Nevrlý, Josef (advisor)
Bachelor thesis solves the problem of a submersible, diagonal hydrostatic pump. This study describes the basic principles of hydraulics and equipment. The possibility of engaging the hydrostatic system as an amphibious vehicle is investigated in the Bachelor thesis. The work is written in cooperation with the sponsor of HYDRAULIC RESEARCH CENTRE, spol. S.r.o., which is part of SPL Holding., Inc.

Comparison of the effect of the two-mass and hydraulic buffers on the impact of the self-loading rifle
Talanda, Jakub ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
The focus of this thesis are the effects of dual-body and hydraulic recoil buffers on measured recoil of an AR-15 type self-loading rifle. The first part explains the working principles of the rifle and both mentioned buffer designs and points out the sources of the recoil effect. A brief summary of contemporary knowledge and already conducted research into the problem follows. The second part describes an experiment in which the recoil force was measured using a force sensor placed between the rifle butt and shooter’s shoulder. At the end, outcomes of this research are discussed and results obtained for both buffer designs are compared.

Models of vehicle´s kinetic energy recovery
Fic, Miloslav ; Vaverka, Michal (referee) ; Nevrlý, Josef (advisor)
The bachelor thesis deals with analysis of existing knowledge in the area of vehicle kinetic energy recuperation models. This analysis is mainly focused on hydrostatic regenerative braking system models. This paper introduces stances of some authors, mathematic relationships and program tools useful for simulation of these models. Afterwards is estimation of shown studies and at least is presented future development of hydrostatic regenerative braking systems. This paper gives a sight of hydraulic recuperation system problems and it could be used as the theoretical element for next research in recuperation models area.
