Modeling and control of a redundantly actuated variable mass 3RRR planar manipulator controlled by a model-based feedforward and a model-based-proportional-derivative feedforward–feedback controller
PublicationIn the paper, dynamics of a complex mechatronics system is considered. A redundantly actuated planar manipulator is the base of the mechanical part of it. It is a 3RRR 1 platform based parallel manipulator. To control its trajectory, a model-based feedforward controller is employed. Three aspects are fundamental in the presented investigations. The first focus is on development of an accurate numerical model used to solve the inverse...

The idea of the heat storage in heat accumulator for car engine preheating before start = Koncepcja wykorzystania ciepła zakumulowanego w cieczy chłodzącej do wstępnego podgrzania silnika samochodu przed kolejnym rozruchem
PublicationSposób eksploatacji samochodów osobowych w miastach charakteryzuje się krótkimi przejazdami, a w przypadku pojazdów kurierów i pojazdów dostawczych również krótkimi postojami z zatrzymaniem silnika. Nowoczesne układy chłodzenia z pompą cieczy chłodzącej z napędem niezależnym od silnika stwarzają możliwość schładzania lub podgrzewania silnika zatrzymanego. Wpływ stanu cieplnego podczas rozruchu na parametry eksploatacyjne był rozważany...

Proposal of a mobile medical waste incinerator with automatic waste feeder and heat recovery system
PublicationThe paper presents and discusses the issue of medical waste (including hazardous ones) and their proper management. Inappropriate handling of infectious medical waste directly endangers the human being health and the environment. Infectious waste must therefore be properly disposed of – one of the most commonly used methods is the thermal treatment in the incinerators tailored for this purpose. During designing an incinerator unit,...

Modelling of saturated, subcooled and post-dryout flow boiling with the energy dissipation based semi-empirical model
PublicationA comprehensive semi-empirical model for saturated, subcooled and post dryout heat transfer is presented based on considerations of energy dissipation in the flow. The fundamental hypothesis in the model is the fact that heat transfer during flow boiling can be treated as a sum of two contributions constituting the total energy dissipation in the flow, namely the energy dissipation due to the shearing flow without the bubbles and...

Increased resonance energy transfer between fluorophores bound to DNA in proximity to metallic silver particles.
PublicationZbadano wpływ nanocząstek metalicznego srebra na rezonansowe przekazywanie energii między fluoroforami związanymi z DNA. Donor (pochodna kumaryny) i akceptor (Cy3) umieszczono na przeciwległych końcach DNA o strukturze podwójnej helisy i o 23 parach bazowych. W nieobecności cząstek srebra wydajność przekazywania energii w tym układzie wynosiła ok. 9%, zaś po umieszczeniu go między kwarcowymi płytkami pokrytymi filmem wysepek...
