Reverse pricing has been recognized as an effective tool to handle demand uncertainty in the travel industry (e.g., airlines and hotels). To investigate its viability for communication networks, we study the practical limitations of (operator-driven) time-dependent pricing that has been recently introduced, taking into account demand uncertainty. Compared to (operator-driven) time-dependent pri...

This research is focused on reducing the average size of the solutions generated by an enhanced GP process without affecting the high predictive accuracy the method exhibits when being applied on a complex, industry proposed, regression problem. As such, the effects the GP enhancements have on bloat have been studied and, finally, a bloat control system based on dynamic depth limiting (DDL) and...

Previous research on university-industry collaboration in Canada concluded, using mean impact factors as a proxy, that the scientific impact of such research is not inferior to that of university research. Using field-normalized impact factors and citation counts, this paper reexamines the Canadian case. It shows that, when impact factors are field-normalized, university-industry papers are pub...

Based on the increasing property of ratio of average reversed hazard rates of two non-negative random variables a new stochastic order for the sake of comparison of two lifetime distributions is proposed. This stochastic order admits some distinguishing properties. In order to illustrate the obtained results, a semi-parametric model which is called reverse hazard power and a mixture model of pr...

A model of industry speed of price adjustment is derived from firm pricing behaviours. The model is applied to quarterly two-digit Australian manufacturing data for the period 1985:3 to 2002:3. Initially, the industry speed of price adjustment is treated as a function of structural cross-section variables. The results suggest that the industry speed of price adjustment is positively related to ...

BACKGROUND Experimental evidence suggests that inhaled particles from vehicle exhaust have systemic effects on inflammation, endothelial activation and oxidative stress. In the present study we assess the relationships of short-term exposures with inflammatory endothelial activation and oxidative stress biomarker levels in a population of trucking industry workers. METHODS Blood and urine sam...

BACKGROUND This study examined the content and general readability of pediatric oral health education materials for parents of young children. METHODS Twenty-seven pediatric oral health pamphlets or brochures from commercial, government, industry, and private nonprofit sources were analyzed for general readability ("usability") according to several parameters: readability, (Flesch-Kincaid gra...

tourism industry is emerging as a new era, one of the main pillars of the economy, the business world. many planners and policy makers in the development of the tourism industry as the main pillars of sustainable development are mentioned. in this direction, this research inspired by these changes and therefore social indicators such as social capital, sense of place, and so on programming usin...
