Shared processor scheduling of multiprocessor jobs
PublikacjaWe study a problem of shared processor scheduling of multiprocessor weighted jobs. Each job can be executed on its private processor and simultaneously on possibly many processors shared by all jobs. This simultaneous execution reduces their completion times due to the processing time overlap. Each of the m shared processors may charge a different fee but otherwise the processors are identical. The goal is to maximize the total...

Experimental certification of more than one bit of quantum randomness in the two inputs and two outputs scenario
PublikacjaOne of the striking properties of quantum mechanics is the occurrence of the Bell-type non-locality. They are a fundamental feature of the theory that allows two parties that share an entangled quantum system to observe correlations stronger than possible in classical physics. In addition to their theoretical significance, non-local correlations have practical applications, such as device-independent randomness generation, providing...

Psychological and physical components in forming preferences on urban greenery management – The case of trees
PublikacjaPublic opinion is increasingly important in managing urban greenery. In this regard, this study demonstrates the importance of sociological (environmental worldviews), psychological (place attachment, perceived benefits of trees), and physical factors (type of building people live in, and urban greenery) in forming residents’ opinions on whether the municipality or landowners should decide about tree removal on private land. Logistic...

Ryzyko realizacji prac projektowych i prowadzenia przebudowy obiektów prywatnych
PublikacjaW artykule przedstawiono przykład realizacji przebudowy prywatnego budynku mieszkalnego, podczas której okazało się, że nie jest on wykonany zgodnie z projektem i zasadami sztuki budowlanej. Opracowany i zatwierdzony projekt budowlany przebudowy niewiele miał wspólnego z obiektem, którego dotyczył. Realizacja prac zgodnie z tym projektem była więc obarczona dużym ryzykiem, a w konsekwencji groziła katastrofą budowlaną.
