Electronic RLC meter
Dvořák, Radim ; Hanák, Pavel (referee) ; Lattenberg, Ivo (advisor)
This work deals with measurement methods of passive components R, L ,C used almost in every electrical circuit. Work describes progress of choosing the right methods for measurement and also the process of designing the autonomous RLC meter with use of ATMEL microprocessor chips. The RLC meter will be powered from rechargable battery and will be able to measure primary attributes of RLC components.

Capacity meter for Li-Ion and NiMH accumulators
Pinďák, Lukáš ; Cipín, Radoslav (referee) ; Huták, Petr (advisor)
The goal of this bachelor thesis is primarily theoretical analysis of battery problems, analysis tester capacity of Li-ion and NiMH accumulators and its subsequent construction. The work consists of three main. The first part deals with the electrochemical current sources and their division, a brief description of their charging and final comparison commonly most used batteries. The second part of the thesis is already focused on the practical design of the capacity meter. In this section is explained the issue of measuring voltage, current and temperature of the battery and determination of their capacity. The last part describes the device software. The proposed devices allow measurement capacity Li-ion and NiMH cells at three different load modes and can be recharged after discharge.

Comparison of architectures of MIB system databases designed for QoS management in data networks
Jelínek, Tomáš ; Hošek, Jiří (referee) ; Molnár, Karol (advisor)
Bachelor thesis deals with Diffserv mechanism for Quality of Service in data network and goes through several parts of structure MIB database for managing Diffserv mechanism. The first chapter is introduction. I explain SNMP protocol in the second chapter. In the third chapter I deal with Quality of Service (QoS) and in the next chapter I explain Diffserv mechanism and its architecture. In fifth chapter I present possibilities of using Policy Information Base (PIB). I show several parts of MIB database in the sixth chapter. I compare two parts of MIB database and summary whole work in the last chapter.

Development of mobile flowmeter
DITRICH, Vít
This thesis contains the description of well-known methods and principles dealing with the measurement of the flow-velocity of fluids. Furthermore, it contains the description of the development of the mobile flow-meter, including the realization and the technical description of the device. The thesis describes the advantages and disadvantages of the above mentioned flow-meter. The last part of the thesis is dedicated to the calibration of the device and to the possible practical use of the flow-meter.
