This paper reports on the development of the prototype African Wordnet (AWN) which currently includes four languages. The resource has been developed by translating Common Base Concepts from English, and currently holds roughly 42 000 synsets. We describe here how some language specific and technical challenges have been overcome and discuss efforts to localise the content of the wordnet and qu...

An ad hoc wireless network (AWN) is a collection of mobile hosts forming a temporary network on the fly, without using any fixed infrastructure. Characteristics of AWNs such as lack of central coordination, mobility of hosts, dynamically varying network topology, and limited availability of resources make QoS provisioning very challenging in such networks. In this paper, we describe the issues ...

Reformulating the user query is a technique that aims to improve the performance of an Information Retrieval System (IRS) in terms of precision and recall. This paper tries to evaluate the technique of query reformulation guided by an external resource for Arabic texts. To do this, various precision and recall measures were conducted and two corpora with different external resources like Arabic...

Fibrotic myopathy of the iliopsoas muscle developed in a dog, following extensive migration of a grass awn within the muscle and adjacent subcutaneous tissue. The dog was initially presented for evaluation of a fluctuant swelling over the right flank region. The clinical and imaging findings were suggestive of iliopsoas fibrotic myopathy and the diagnosis was confirmed by histopathology. This i...

This paper is concerned with the distribution in the complex plane of the roots of a polynomial sequence {Wn(x)}n≥0 given by a recursion Wn(x) = aWn−1(x) + (bx + c)Wn−2(x), with W0(x) = 1 and W1(x) = t(x − r), where a > 0, b > 0, and c, t, r ∈ R. Our results include proof of the distinct-real-rootedness of every such polynomial Wn(x), derivation of the best bound for the zero-set {x | Wn(x) = 0...
