PL Miasta są w ciągłym ruchu i nieustannie się zmieniają. Ostatnie pięćdziesiąt lat pokazało nam jak wiele może się zmienić w tak krótkim czasie. Po II wojnie światowej coraz większa powszechność samochodu oraz powstające teorie strefowania funkcji w urbanistyce spowodowały niesamowity wzrost mobilnośc[...]
EN Our cities are in constant movement and incessant changes. The past fifty years showed us that a lot can change in a very short period of time. After World War II the car and the theories of urban zoning caused the amazing increase of mobility. What is happening now when the mobility just exist, is [...]

EN In this work we present the model of ``mobile object net systems'' - an algebraic formalisation of the ``nets within nets''-paradigm. The formalism of ``mobile object nets'' is well suited to express the dynamics of open, mobile systems, since it allows tokens to be active. The algebraic theory of `[...]

Opto - Electronics Review
EN We investigated single crystals of GaN and thin film GaN radiation detectors by thermally stimulated currents (TSCs) and thermally stimulated depolarization (TSD) methods in order to characterize carrier transport properties as influenced by material defect structure. In thick GaN, no expressed stru[...]

PL Jedną z podstawowych właściwości charakteryzujących pojazdy bojowe lub specjalne transportowe, niezależnie od rodzaju podwozia, jest ich zdolność do poruszania się po dowolnych drogach oraz pokonywania różnego rodzaju przeszkód terenowych naturalnych i sztucznych. Pojazdy te na swojej drodze mogą na[...]
EN One of the basic characteristic that characterize combat vehicles or transportation special vehicles, regardless of type of vehicle, is ability to move along any kind of roads as well as overcome different kind of off road obstacles natural and artificial. These vehicles on their road can encounter [...]

Opto - Electronics Review
EN We report on the results of transport studies of MBE-grown InAs/GaSb superlattices. We demonstrate that the in-plane mobility is limited by interface roughness scattering by showing that, as a function of InAs layer width L, the in-plane mobility behaves as μ ∝ L5.3, which closely follows[...]
