    The Influence of the Type of Electrodes on the Biological Impedance Measurement
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2016) Prokopyeva, Elena
    Electric impedance during meat storage can be affected by various processes: microbial growth, changing of ions mobility, structural changes, etc. Impedance of biological tissues is frequency dependent. The aim of current study is to determine and evaluate the impedance properties of pork meat using two types of electrodes. Measurements were performed during three days in frequency range 100 Hz ÷ 1 MHz.

    Stability of the Zero Solution of Stochastic Differential System
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2016) Klimešová, Marie
    Stability of stochastic differential equations (SDEs) has become a very popular theme of recent research in mathematics and its applications. The method of Lyapunov functions for the analysis of qualitative behavior of SDEs provide some very powerful instruments in the study of stability properties for concrete stochastic dynamical systems, conditions of existence the stationary solutions of SDEs and related problems.

    Automated Electrochemical Etching Prototype for Cold Field Emission Cathodes
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2016) Jurčík, Michal
    This article deals with a setup for automated cold cathode etching, its difficulties and benefits. As the method is well know there are no articles which describes this procedure in detail at least for tungsten wires from which cathodes are made. To provide stable and repeatable process of cathodes manufacturing, the experimental setup was proposed with full hardware control with aim to assure etching circuit disconnection in order of hundreds of nanoseconds.

    Solution of a Weakly Delayed Difference System
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2016) Šafařík, Jan
    The paper solves a weakly delayed difference systém x(k+1) = Ax(k)+Bx(k-1) where k = 0;1; : : : , A = (ai j)3 i; j=1, B = (bi j)3i ; j=1 are constant matrices. An explicit solution is given with a discussion on the number of independent initial data.

    Computer-assisted Search of the Roots of the Polynomial
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2016) Smetana, Bedřich
    This article describes finding roots of polynomials, specifically aimed at finding real roots of a polynomial. Computer Support focuses on the use of generally available programs such as spreadsheets, portals to solve mathematical problems and freeware applications. Attention is devoted to a comparison of commercial and open source software.
