Digital Gaps and Economic Inequalities in MENA Countries: An Empirical Investigation
PublikacjaThis research contributes to the present state of the art by examining changes in cross-country inequalities in digital technologies deployment and economic performance. Our empirical target builds on the hypothesis that rapid global diffusion of digital technologies unequivocally leads to gradual eradication of cross-country digital gaps and cross-country inequalities in terms of deployment of ICT; the technology convergence occurs....

Public valuation of social impacts. The comparison between mega and non-mega sporting events
PublikacjaThe main aim of this study is to assign value to intangible effects,including social impacts, which appear when organising sportingevents of various scales in the city of Gdansk located in northernPoland. A survey was conducted to determine the city residents’willingness-to-pay (WTP) using the contingent valuation method(CVM). The average WTP values, which ranged between PLN 6.04and PLN 46.34, show that the scale of the sporting...

Does one currency mean one price?
PublikacjaEuropean Monetary Union was expected to have many consequences for the economies of participant countries. Theory suggested that through a higher volume of trade and stronger competition in the Eurozone, a single currency would lead to a reduction in price dispersion. As far as prices are concerned, two effects were expected: an immediate effect due to the technical characteristics of the changeover process, and a long-term one...

Does low price mean high competitiveness
PublikacjaWe found a strong positive relationship between Comparative Price Level Index (CPL) and Growth Competitiveness Index (GCI). We do realize that the relation we have found does not have to indicate cause and effects relationship. Competitiveness is a process which goes far beyond price level but it is detemined by lots of different elemnts. We show the GCI composition that provides a concept explaining what exactly determines competitiveness...

The impact of mega sports events on the stock markets
PublikacjaWpływ wielkoformatowych imprez sportowych na gospodarkę może być rozpatrywany na różnych płaszczyznach. Najczęściej przywołuje się zmiany w zakresie PKB kraju lub regionu goszczącego, zmiany na rynku pracy, rozbudowę bądź modernizację infrastruktury oraz tendencje w zakresie przepływu turystycznego. Kanały oddziaływania tak dużych wydarzeń są jednak dużo szersze i obejmują ponadto: życie publiczne, polityczne i kulturalne, informację,...

Dedicated scheduling of tasks to minimize mean flow time
PublikacjaThis paper investigates the complexity of scheduling biprocessor tasks on dedicated processors to minimize mean flow time. Since the general problem is strongly NP-hard, we assume some restrictions on task lengths and the structure of associated scheduling graphs. Of particular interest are acyclic graphs. In this way we identify a borderline between NP-hard and polynomially solvable special cases.

Social benefits valuation of hosting non-mega sporting events
PublikacjaPurpose In the study, an attempt was made to estimate the social benefits resulting from three non-mega sporting events organized in Ergo Arena located on the border of two cities in Poland. By attributing a value to intangible social benefits, the intangible effect was determined and compared to the expenditure incurred in the construction of Ergo Arena Hall. Design/methodology/approach In order to value social intangible effects...

MEAN SHIFT BASED SEGMENTATION FOR BLEEDING REGIONS IN ENDOSCOPIC VIDEOS
PublikacjaWith a set of 38 manually marked bleeding regions form endoscopic videos, the authors attempted to find an optimal image segmentation method for reproducing doctor’s markup. Mean shift segmentation combined with HSV histogram segmentation were used as a segmentation method, which was then optimized by tuning the parameters of the method using global optimization algorithm. A target function for measuring the quality of segmentation was...

Tangible and intangible economic impact of hosting mega sporting events
PublikacjaDue to the fact that the impetus for the creation of this paper was inaccuracies in the results of research relating to the economic effects caused by the organisation of mega sporting events, an analysis of the impact of 1988-2008 mega sporting events on host economies was conducted. The research shows that in selected areas of the economy, sporting events can be identified, with occasional positive (SOG) and negative (WOG) economic...

A space-efficient algorithm for computing the minimum cycle mean in a directed graph
PublikacjaAn algorithm is introduced for computing the minimum cycle mean in a strongly connected directed graph with n vertices and m arcs that requires O(n) working space. This is a considerable improvement for sparse graphs in comparison to the classical algorithms that require O(n^2) working space. The time complexity of the algorithm is still O(nm). An implementation in C++ is made publicly available at http://www.pawelpilarczyk.com/cymealg/.

An Approach to Mean Path Loss Model Estimation for Off-Body Channels
PublikacjaThis paper presents an approach to estimation of the mean path loss model parameters in off-body Body Area Networks channels. In this approach, the path loss exponent is constrained to a value obtained for the line-of-sight (LoS) propagation in the co-polarised channel, considering a generalised static scenario. The comparison of the goodness of fit between the proposed approach and other approaches, for a set of measurements obtained...
