Cloud computing enables shared servers to provide resources, software and data for collaborative services on demand with high interoperability and scalability. However, there are a number of technical challenges that need to be tackled before these benefits can be fully realized, which include system reliability, resource provisioning, and efficient(More)
1 Partition Testing The term " partition testing " , in its broadest sense, refers to a very general family of testing strategies. The primary characteristic is that the program's input domain is divided into subsets, with the tester selecting one or more element from each subdomain. In this paper, we shall not restrict the term " partition " to the formal(More)
Electronic commerce has changed the outlook of traditional business trading behavior. It is now common to see business-to-business (B2B), business-to-consumer (B2C) and consumer-to-consumer (C2C) commerce on the Internet. However, another type of model, consumer to business (C2B), is seldom found. A possible reason for this phenomenon is transaction cost;(More)
A simplified form of domain testing is proposed that is substantially cheaper than previously proposed versions, and is applicable to a much larger class of programs. In particular, the traditional restrictions to programs containing only linear predicates and variables defined over continuous domains are removed. In addition, an approach to path selectlon(More)
Inductive learning that creates decision trees from a set of existing cases is useful for automated knowledge acquisition. Most of the existing methods in literature are based on crisp concepts that are weak in handling marginal cases. In this paper, we present a fuzzy inductive learning method that integrates the fuzzy set theory into the regular inductive(More)
Wireless sensor networks provide an alternative way of improving our environments, such as environment surveillance, hazard monitoring, and other customized environmental applications. Good coverage of service in a sensor network is an essential issue to ensure the service of quality. This paper studies the deployment of new sensor nodes so that the(More)
