Recently there have been numerous studies exploring the benefits of the coalition formation in a cognitive radio network and it has been shown that coalition formation tends to improve the performance of cognitive radio. In this paper we use the concepts from matching theory, specifically we use Gale-Shapley algorithm, to form the coalition among cognitive radio user for collaborative spectrum ...

BACKGROUND The early years in children's life are the key to physical, cognitive-language, and, socio-emotional skills development. So, it is of paramount importance in this period to be interested in different indicators that would influence the child's health. METHODS This paper measures inequality of opportunities among Tunisian children concerning access to nutritional and healthy service...

The electrical market scenario has changed drastically in the last decade. In presence of increased competition and less tolerant players, more sophisticated methods are required to balance diversity differential pricing while promoting cooperation among agents. monopolistic environment, central utility incurred total cost transmission expansion. But as current demands, there several public pri...

As a critical aspect of corporate financing strategies, high-quality trade credit has been acknowledged as favorable indicator for external stakeholders. Given the increasing prominence sustainable development, it is worthwhile to explore whether an advanced environmental management system facilitates attainment business operations.

Due to disordered structure, glasses present a unique challenge in predicting the composition–property relationships. Here, we low-complexity neural network (LCNN) that provides improved performance properties of oxide glasses. In addition, combine LCNN with physical and chemical descriptors allow development universal models can provide predictions for components beyond training set. By on lar...

Caching of popular contents at cellular base stations, i.e., edge caching, in order to eliminate duplicate transmission through the backhaul can reduce the latency of data delivery in 5G networks. However, since caching can only reduce the backhaul delay, techniques such as base station densification will also need to be used to reduce the fronthaul delay. In this paper, using results from stoc...
