Temperature effect on the current-voltage characteristic fill factor for the silicon solar cells
PublikacjaW pracy przedstawiono badania wpływu temperatury pracy krzemowych ogniw fotowoltaicznych na wartość współczynnika wypełnienia charakterystyki prądowo- napięciowej (FF). Efekty dyfuzyjne w obszarze złącza oraz rekombinacja nośników ładunku ograniczają wartość współczynnika wypełnienia charakterystyki. Spadek tej wartości wynika głównie ze wzrostu wartości rezystancji szeregowej rs. Na rezystancję szeregową składają się: opór emitera...

The formal safety assessment and influence of human factor in application to chosen ship's type
PublikacjaTragedia jednego ze statków typu ro-ro pokazała podatność tego typu statków na utratę stateczności, przewrócenie się, a w ostateczności zatonięcie. Wszystkie ro-rowce charakteryzują się małym zanurzeniem, a wynurzona część kadłuba podatna jest na działanie wiatru. Jeżeli dodatkowo w takich warunkach dochodzi element nieprawidłowego rozmieszczenia pojazdów i ich słabego zamocowania to groźba przesunięcia ładunku staje się realna....

Constant-Factor Approximation Algorithm for Binary Search in Trees with Monotonic Query Times
PublikacjaWe consider a generalization of binary search in linear orders to the domain of weighted trees. The goal is to design an adaptive search strategy whose aim is to locate an unknown target vertex of a given tree. Each query to a vertex v incurs a non-negative cost ω(v) (that can be interpreted as the duration of the query) and returns a feedback that either v is the target or the edge incident to v is given that is on the path towards...

Interaction of the conserved region 4.2 of sigma(E) with the RseA anti-sigma factor
PublikacjaEo-E RNA polymerase transcribes a regulon of folding factors for the bacterial envelope and is induced by physical and chemical stresses. The RseA anti-sigma factor inhibits the activity of Esigma(E) RNA, polymerase. It is shown here that the N-terminal portion of sigma(E), residues 1-153, binds core RNA polymerase. RseA interacts with residues 154-191 of sigma(E), a site that is homologous to region 4, the sigma factor binding...

Hydrophobic and hydrophilic properties of pollutants as a factor influencing their redistribution during snowpack melt
PublikacjaGlaciers accumulate organic pollutants delivered by snow. However, our understanding of the exact dynamics of organic pollutants in the snowpack relies primarily on laboratory experiments and mathematical models. To fill the gap related to the detailed field data, we have conducted observations of melting snow profiles in two locations and three different stages of melting on one High Arctic glacier, as well as in superimposed...

The Factors Affecting Group Identity of Cluster Structures
PublikacjaThe paper provides a new approach to cluster analysis, basing on a sociologically rooted concept of identity. The authors state that identity in cluster structures is formed by two main groups of factors – uncontrollable or slightly controllable factors (identity mix) and factors that can be fully controlled by a cluster initiative (corporate identity mix). It means that the cluster coordinator is able to consciously build the...
