Experimental validation of the parasitic RC components extraction (PEX extraction) using ring oscillators
 Buzek, Vít ; Král, Vojtěch (referee) ; Hejátková, Edita (advisor)
The main focus of this work is verification of extraction of parasitic RC components. The theoretical part is concerned with theoretical terms from the area of design of integrated circuits, ring oscillators, parasitic extraction and frequency counting are clarified. The practical section is dedicated to measuring at manufactured structures on a silicon wafer and simulation, which simulates the designed structures in Cadence Virtuoso. For the parasitic extraction to be verified, it is necessary to compare the measured and simulation frequencies, to find out the deviations and to point out configurations with limited accuracy. Section of the practical part is dedicated to statistical analysis and suggestion on improving the parasitic extraction.

Měření přestupu tepla a frekvence oscilací s fluidickým generátorem syntetizovaného impaktního proudu
 Tesař, Václav ; Trávníček, Zdeněk ; Kordík, Jozef ; Randa, Zdeněk
The paper discusses recent results of an experimental research of annular impinging hybrid-synthetic jets generated by a no-moving-part fluidic actuator. The actuator is based on a new principle and the first part of the paper discusses the basic configuration idea and the relationship with earlier hybrid-synthetic jet generators. The next part of the paper provides information of a strange phenomenon – an unexpected high-temperature region found on the impingement surface. Also discussed are the measurements of the oscillation frequency. The most important result is the substantial increase of heat transfer efficiency compared with the steady flow from the same nozzles.
