Quasi-analytical Near-to-Far Field Transformation Based on Field Matching Method for Scattering Problems
PublikacjaA new quasi-analytical near-to-far field transformation based on field matching method (field expansion in a base of Hankel functions) is presented. This approach uses finite element method to obtain near field, then the field is expressed in a base of Hankel functions. The evaluated coefficients allow to calculate the field outside the numerical domain, also in a far distance. The main advantage of the proposed technique is avoiding of...

A preliminary study for identifying olfactory markers of fear in the rat
PublikacjaW sytuacjach stresowych wiele zwierząt wydziela feromony alarmowe aby ostrzec inne osobniki o nieuchronnym zagrożeniu. Autorzy szukali warunków doświadczalnych, mających na celu identyfikację feromonów alarmowych wydzielanych przez szczury. Szczury umieszczono w specjalnie zaprojektowanych komorach i narażono na różne dotykowe, wizualne i akustyczne bodźce w przeciągu kilku dni. Badacze obserwowali zachowanie szczurów i analizowali...

A Comparative Study on Methods of Distinction Between Near- and Far-Side Defects as Techniques Used Alongside with the Magnetic Flux Leakage Testing
PublikacjaResults of the finite element analysis show that a far-side defect in a steel plate, with the depth greater by 10% of the plate thickness than a near-side defect, can produce a very similar magnetic flux leakage (MFL) signal. Due to the fact that a measurement of MFL itself can lead to misclassification of a far-side defect as a near-side one, and thus to underestimation of its depth, a comparative study of three complementary...

On the Consumption of Multimedia Content Using Mobile Devices: a Year to Year User Case Study
PublikacjaIn the early days, consumption of multimedia content related with audio signals was only possible in a stationary manner. The music player was located at home, with a necessary physical drive. An alternative way for an individual was to attend a live performance at a concert hall or host a private concert at home. To sum up, audio-visual effects were only reserved for a narrow group of recipients. Today, thanks to portable players,...

Correlations between the wear of car brake friction materials and airborne wear particle emissions
PublikacjaAirborne wear particles emitted from transport vehicle brakes are one of the main sources of toxic metals in inhalable particulate matter. Prediction of wear particle emissions may become more accurate if the relationship between the wear and particle emission characteristics is known. An experimental study was performed to investigate proportional correlations between the mass wear, 0.01–0.42 μm particle emission measured by a NanoScan...

Water Behavior Near the Lipid Bilayer
PublikacjaIn this chapter, we focus on the dynamics of water molecules situated in the vicinity of a phospholipid bilayer. Using a molecular dynamics simulation method, we studied interactions between water and the bilayer and tracked trajectories of the water molecules. Based on the hypothesis that molecules trapped inside the bilayer make different motions than the ones which are either attached to the surface or move freely in the water...

Theory and application of Near-infrared spectroscopy
PublikacjaIn recent years one can observe a significant increase in the requirements on quality control in all industrial sectors. The growing number of involved analyses makes the traditional, time consuming, requiring use of large quantities of reagents, thus expansive methods inconvenient especially for industrial applications. Fortunately, there is a very fast, cheap and not invasive analytical method that is increasingly used in qualitative...

The integrals of velocity near the tissue in bioreactor.
PublikacjaWykazano, że siły tarcia występujące w trakcie hodowli decydują o jakości wzostu tkanki i jej planowanych, zamierzanych właściwościach. Siły tarcia wyznaczamy z pola prędkości cieczy biologicznej przepływającej wokół powierzchni tkanki. Dlatego w pracy tej wyznacza się pole prędkości przepływu cieczy biologicznej w cienkiej warstewce przyściennej. Wyznaczone analitycznie pole prędkości charakteryzuje się newtonowskimi właściwościami...
