  Rolling resistance of tires is one of the most important factors influencing energy consumption of road vehicles, especially on rural roads. For practical reasons, most of rolling resistance measurements are usually performed for dry road conditions. Based on the fact that roads are wet during a considerable time over the year and as part of the projects MIRIAM, ROLRES and ROSANNE, the TUG (Technical University of Gdańsk) in Poland...

  Mimo podejmowanych wielu działań w zakresie brd na sieci dróg krajowych w Polsce, rezultaty są dalekie od oczekiwań i zadań postawionych przez Krajowy Program BRD GAMBIT 2005. Można by to tłumaczyć dużym przyrostem liczby pojazdów i wzrostem pracy przewozowej szczególnie na drogach krajowych. Ale porównanie ryzyka występującego na sieci dróg krajowych w Polsce do ryzyka występującego na drogach krajowych najbliższych krajów europejskich...

  While it is usually known that the mean value of a single observable is enough to detect entanglement or its distillability, the counterpart of such an approach in the case of quantum privacy has been missing. Here we develop the concept of a privacy witness, i.e., a single observable that may detect the presence of the secure key even in the case of bound entanglement. Then we develop the notion of secret-key estimation based...

  This paper presents an overview of factors causing driver fatigue as described in the literature. Next, a traffic crash database for 2003–2007 is used to identify the causes, circumstances and consequences of accidents caused by driver fatigue on Poland’s national roads. The results of the study were used to build a model showing the relationship between the concentration of road accidents and casualties, and the time of day. Finally,...

  - PHYSICAL REVIEW A - Year 2013

  The separability problem is formulated in terms of a characterization of a single entanglement witness. More specifically, we show that any (in general multipartite) state rho is separable if and only if a specially constructed entanglement witness W-rho is weakly optimal, i.e., its expectation value vanishes on at least one product vector. Interestingly, the witness can always be chosen to be decomposable. Our result changes the...
