Recently, there has been a substantial growth in mobile data traffic due to the widespread of data hungry devices such as smart handsets and laptops. This has encouraged researchers and system designers to develop a further efficient network design. The objective of this paper is to overview the technologies that can support multi Gbps for future Fifth Generation (5G) network. This paper presen...

We study the performance of Arabic text classification combining various techniques: (a) tfidf vs. dependency syntax, for feature selection and weighting; (b) class association rules vs. support vector machines, for classification. The Arabic text is used in two forms: rootified and lightly stemmed. The results we obtain show that lightly stemmed text leads to better performance than rootified ...

Text categorization is an important application of machine learning to the field of document information retrieval. Most machine learning methods treat text documents as a feature vectors. We report text categorization accuracy for different types of features and different types of feature weights. The comparison of these classifiers shows that stemmed or un-stemmed single words as features giv...

East African Blackwood is the common name for Dalbergia melanoxylon, the most valuable timber growing in the Miombo woodlands of southern Tanzania, and a potential flagship species to justify conservation of this habitat.
