An auction platform is a dynamic environment where a rich variety of social effects can be observed. Most of those effects remain unnoticed or even hidden to ordinary users. The in-depth studies of such effects should allow us to identify and understand the key factors influencing users’ behaviour. The material collected from the biggest Polish auction house has been analyzed. NLP algorithms we...

INTRODUCTION The paper presents the methods of cultural adaptation of the Newcastle Satisfaction with Nursing Scale (NSNS) to the conditions in Polish hospitals. MATERIAL AND METHODS The process of cultural adaptation of the research tool took into consideration an analysis of different equivalence levels, the translation procedure and the estimation of psychometric parameters. The Polish ver...

Using the backpropagation algorithm, we have trained the feed forward neural network to pronounce Polish language, more precisely to translate Polish text into its phonematic counterpart. Depending on the input coding and network architecture, 88%-95% translation eeciency was achieved.

An automatic speech recognition system for Polish is demonstrated. A few layers of our system are different from popular approaches as a result of differences between Polish and English languages.

We generalize some model theory involving Hyp(M) and HF(M) to the case of actions of Polish groups on Polish spaces. In particular we obtain two variants of the Nadel’s theorem about relationships between Scott sentences and admissible sets.

BACKGROUND Financial analysis (budget impact analysis, BIA) is increasingly required by decision-makers to ascertain the macroeconomic consequences of new product reimbursement in addition to proof of cost-effectiveness. Poland is in the process of drafting country-specific guidelines for BIA, positioned as complementary to economic evaluation in decision-making OBJECTIVES The aim of this art...

In dynamical systems examples are common in which two or more attractors coexist and in such cases the basin boundary is non-empty. The purpose of this paper is to describe the structure and properties of basins and their boundaries for two-dimensional diffeomorphisms. If a two-dimensional basin has a basin cell (a trapping region whose boundary consists of pieces of the stable and unstable man...

The hydrothermal sediments of Guaymas Basin, an active spreading center in the Gulf of California (Mexico), are rich in porewater methane, short-chain alkanes, sulfate and sulfide, and provide a model system to explore habitat preferences of microorganisms, including sulfate-dependent, methane- and short chain alkane-oxidizing microbial communities. In this study, hot sediments (above 60°C) cov...

Recent concern about survival and recovery of highelevation white pine ecosystems has returned white pine blister rust (caused by Cronartium ribicola) to prominence as a significant threat to forest health in the western U.S. (Samman et al., 2003). This, in turn, has spurred new research into potential rustresistance mechanisms in high-elevation white pines, including whitebark (Pinus albicauli...
