Speaker Recognition in the VoIP Environment
Remeš, Jan ; Pešán, Jan (referee) ; Plchot, Oldřich (advisor)
Tato práce popisuje použití systémů pro rozpoznávání mluvčího v~prostředí VoIP, úspěšnost systému a přístupy k jejímu zlepšení. Popisuje architekturu těchto systémů, metriky pro vyhodnocení jejich úspěšnosti a klíčové komponenty VoIP z hlediska rozpoznávání mluvčího. Je zde popsáno vytvoření simulace VoIP prostředí, úspěšnost systému je vyhodnocena na datech pocházejících z různých druhů VoIP prostředí a výsledky jsou demostrovány. Adaptace a kalibrace systému je provedena a jejich přínosy zhodnoceny.

Virtualization of I/O Operations in Computer Networks
Remeš, Jan ; Martínek, Tomáš (referee) ; Matoušek, Denis (advisor)
This work deals with virtualization of computer systems and network cards in high-speed computer networks, and describes implementation of the SR-IOV virtualization technology support in the COMBO network card platform. Various approaches towards network card virtualization are compared, and the benefits of the SR-IOV technology for high performance applications are described. The work gives overview of the COMBO platform and describes design and implementation of the SR-IOV technology support for the COMBO platform. The work concludes with measurement and analysis of the implemented technology performance in virtual machines. The result of this work is the COMBO cards' support for the SR-IOV technology, which makes it possible to use them in virtual machines with wire-speed performance preserved. This allows future COMBO cards to be used as accelerators in the networks utilizing the Network Function Virtualization.

Teorie a konstrukce mlátících ústrojí sklízecích mlatiček
Remeš, Jan
The thesis describes the history and the history of threshing grain combine harvesters. The paper describes the types of threshing unit. They are given energy indicators, the main technical data threshing system and their calculation. The paper gives an overview of the performance categories, sales, capital costs, operating costs and on the percentage of combine harvesters on the market today. The following describes the structure threshing device manufacturers marks Case, Claas, John Deere and New Holland, and there is shown a graphical comparison of their technical parameters. The work describes the mass flow threshing mechanism. Theoretical calculation is expressed by the dependence of flow quantity on the length of the threshing drum and then compared with the actual measured values.

Vliv nastavení regulační hydrauliky traktoru na výstupní parametry orební soupravy
Remeš, Jan
The present thesis entitled "Impact of the tractor control hydraulics setting on the output parameters of the tilling system" in its reference part surveys the current state of the design of hydraulic systems in agricultural tractors. The practical part of the thesis is focused on implementation and evaluation of experimental measurement. The measurement employed a tilling system featuring a tractor Class Axion 850 and a four-furrow mounted plough Kverneland EG 85 Variomat. The goal was to identify the effects of various types of hydraulic system controls on the fuel consumption, drive slip and tilling system performance. The measured values have been processed and presented in tables and graphics. The conclusion has been formulated on the basis of the identified results.
