Ubiquitous communication will be one of the paradigms for the next decades. Mobile communication systems experience tremendous growth rates, Internet access is integrated in vehicles, pedestrians use Internet-ready mobile phones. This use of the Internet demands for a highly reliable and secure system, especially when used in nonacademical environments like remote offices, e-commerce, or traffi...

Feature-based conditional statistical methods are essential for the analysis of complex, large-scale data. We introduce two shape-based conditional analysis algorithms that can be deployed in complementary settings: local methods are required when the phenomena under study comprise many small intermittent features, while global shape methods are required to study large-scale structures. We pres...

Linked Services bring together the principles and technology which define Linked Data with those of RESTful services. Services and APIs are thus enriched by, and contribute to, the Web of Data. A number of approaches to the semantic description of services have chosen SPARQL graph patterns as a means to describe input and output expectations. This paper describes two contributions. Firstly, the...

The study investigated the effect of Community-Based Paid Extension (CPE) on vulnerability reduction of smallholder dairy farmers. Randomly sampled 255 farmers were interviewed together with 15 key informants’ interview. Both statistical analysis and thematic approach were employed to achieve triangulation. In about 68 % of cases, CPE reduced vulnerability to a degree experienced as ‘moderate’,...

Locating content efficiently and conveniently is the key issue in P2P systems. In this paper we present SemanticPeer, an Ontology-Based P2P lookup service, to address this problem, which is an extension of Chord protocol. In SemanticPeer, one can easily locate desired data items using the domain knowledge, beyond the keywords scheme. By the separate of share knowledge and private knowledge, Sem...

The aim of this paper is to propose and evaluate GreenMACC (Green Metascheduler Architecture to Provide QoS in Cloud Computing), an extension of the MACC architecture (Metascheduler Architecture to provide QoS in Cloud Computing) which uses greenIT techniques to provide Quality of Service. The paper provides an evaluation of the performance of the policies in the four stages of scheduling focus...

The National Health Service and the private sector should be complementary; each needs the other. It is highly improbable that the Health Service will be privatised; much more likely that private practice will be publicised by bringing it within the National Health Service. This article discusses the size and growth of the private sector, looks at cost containment and quality and examines the p...
