Detection of thermal radiation using lanthanum-strontium-iron oxide (LSFO) bolometers
PublikacjaW artykule przedstawiono bolometr wykonany z tlenków lantanowo-strontowo-żelazowych zastosowany do detekcji promienowania podczerwonego. Parametry bolometru były badane za pomocą wzorcowego źródła poromieniowania o temperaturze 38°C (311 K) oddalonego od bolometru o 500 mm. W trakcie pomiarów uzyskano stosunek sygnał/szum wynoszący ok. 62 (tj. 35.9 dB). Na podstawie wyników pomiarów oszacowano dokładność pomiaru temperatury za...

The power of silence? opinion contagion and the surprise of the polish 2005 parlamentary and presidential elections
PublikacjaThis paper investigates opinion contagion in collective behaviour using threshold model (Granovetter (1978), Krassa(1988)). The theoretical background is the spiral of silence concept developed by Noelle-Neumann (1974), arguing that people only assert their opinions if they perceive a minimal support from a relevant proportion of others. We apply the model to explain the dispersion between pre-elections preferences and the final...

Automatic detection and correction of detuned singing system for use with query-by-humming applications
PublikacjaThe aim of the paper is to present an idea of using the automatic detection and correction of detuned singing as a subsystem in query-by-humming (QBH) applications. The common approach to searching for a requested song basing on the melody retrieved from hummed pattern usually employs the so-called Parsons code or melody contour. In such a case information about sound pitch is discarded. It was thought out that an additional module...

Influence of statistical errors on damage detection based on structuralflexibility and mode shape curvature
PublikacjaDamage detection procedures based on measured natural frequencies and building structure mode shapes are discussed in this paper. Modal curvature and structural flexibility approaches are tested. Attention is paid to the modal identification errors that influence damage detection. This problem is studied using a computer simulation of a simple supported beam. For practical cases, the peak picking methodand its statistical errors...

Detection of Blastocystis hominis in unpreserved stool specimens byusing polymerase chain reaction
PublikacjaBlastocystis hominis jest pasożytem występującym na całym świecie. Patogenność tego pasożyta nie jest jeszcze w pełni udowodniona, aczkolwiek opisanych jest wiele przypadków, sugerujących, że B. hominis może wywoływać objawy żołądkowo-jelitowe. Wykrywanie tego pasożyta opiera się na bezpośredniej obserwacji mikroskopowej rozmazów i zagęszczonych próbek kału lub rozmazów utrwalonych, jednakże w pewnych przypadkach nie jest to możliwe.Celem...
