Antistatistic properties of materials in engineering practice
Vodička, Tomáš ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
The bachelor thesis deals with the properties of antistatic materials in engineering practice. The theoretical part described mathematically and physically electric field, the principle of electrification, triboelectric effect, types of electrostatic discharges, types of antitatic materials and methods of measurement surface and volume resistivity. In the practical part is designed the automated measuring workplace with electrometer Keithley 6517 and with the test chamber Keithley 8009, creating an application in Agilent VEE Pro, measurement of surface and volume resistivity on commercial materials and materials with various surface finishes, realized by cathode sputtering and the inclusion of materials in each group.

Design and construction of measuring equipment for lightning research
Kirsanov, Ivan ; Krajsa, Ondřej (referee) ; Roubal, Zdeněk (advisor)
The main aim of this semester work is the design of meter of an electrostatic field in the open landscape. The theoretical part focuses on describing the theory of the creation of an electrostatic field and on proven measurement methods. The practical part of the bachelor's work is focused on the design of a measuring instrument, selection of components and justification. The practical part includes a block diagram of wiring.

Computation of 3D Electrostatic Fields Excited by Thin Conductors
Karban, P. ; Škopek, M. ; Doležel, Ivo
Solution of 3D electric fields in a system of thin charged conductors of general shapes by classical differential methods (FDM, FEM etc.) is extremely difficult due to ignorance of boundary conditions and existence of geomertically incommensurable subdomainswithin the investigated area. Application of integral methods is also complicated because the kernel functions occuring in the first-kind Fredholm equations are intergrable only in 2D and not in 1D.
