Voice over IP (VoIP) applications can choose a plethora of different speech codecs, which differ in bandwidth, listening speech quality, and resilience to quality degradation under packet loss. However, VoIP Codecs also exhibit differences in facets such as computational complexity or traffic generated that impact on the energy consumption of smartphones due to the use of processor. This work d...

We develop an agent-based modeling and simulation approach to study the impact of product consumption strategies on the temporal dynamics of recommender systems’ performance. We model the product consumption strategy by decomposing it into two parts: recommender system’s item ranking strategy and consumers’ item selection strategy. Our simulation results show that consumers’ selection strategy ...

energy consumption has been essential to societies; because societies depend on the rising provisions of energy to meet their requirements for goods and services and endorse sustainable development. the major source of energy nowadays is oil; oil consumption is dependent on oil availability, production and price. several arab countries are considered as major suppliers of oil in the world; cons...

this study investigated the factors affecting the consumption of cosmetics and its use was in fact one of the manifestations of consumerism that is feminine. due to the growing dilemma of women use cosmetics and fashion remembered more as a social issue will be raised. survey results from a sample of 384, a cluster sampling, random, people through cochran formula for women 18-48 years who had b...

One can use the Leiden Rankings for grouping research universities by considering universities which are not significantly different as a homogeneous set. Such groupings reduce the complexity of the rankings without losing information. We pursue this classification using both statistical significance and effect sizes of differences among 902 universities in 54 countries; we focus on the UK, Ger...

The exchangeability assumption as defined in this paper on ranking functions seems intuitively natural, and indeed, specific ranking functions previously proposed in the literature are all exchangeable. While pointwise ranking functions are vacuously exchangeable, we now discuss two specifically listwise ranking functions previously proposed by [22] and [26] in light of our representation theor...
