These devices can serve two important functions in Grid environment either as service consumer or as valuable service providers. However, there are a number of challenging issues in using a mobile device as service consumer in Grid systems when this fluctuating mobile environment is taken into consideration.

These properties may include life span of the sensors and their distance measurements from a decision centre. The data generated in probabilities representations are fitted with the Exponential, Gaussian and Fourier functions to enable decision taking. Of the three functions, Fourier series was estimated to be the best function for the curve fitting both graphically and numerically as shown through the
experiments. It has a far and wider predictive horizon beyond the data locations than the other distributive functions.

Therefore, semantic web provides infrastructure enabling the semantic interoperability and dependability of web services. Web-based learning is one of the tool with which education is now being delivered. Semantic Web Services, which are services that are self-described and amendable to automated discovery, composition and invocation, will form the next generation of the Web. These services can be represented using ontology and rendered for use by end consumers. An increasing number of organizations are turning to Service Oriented Architectures (SOAs) to consolidate and re-purpose their applications. This can also be extended to include web-based learning applications. As the web service infrastructure matures and first-generation SOAs move to the mainstream, a new revolution in service-orientation is emerging. Web service providers are interconnecting their offerings in unforeseen ways, giving rise to ‘Web Service Ecosystems’-a logical collection of web services whose exposure and access are subject to constraints characteristics of business service delivery. Web service ecosystems make explicit the notion of service procurement, separating it from that of conventional service supply. This study therefore, discusses the vision for web service ecosystems presents a framework design to support its application in the area of web-based learning.

Products and services that affect people's lives must have quality attributes. Therefore, good quality software package is required and in order to determine the quality of software package we need methods to measure it reliability. An interesting point here is that the quality of software may change over time and software package is no exception. In the early days of computing, software costs represented a small percentage of the overall cost of a computer-based system. Hence, a sizable error in estimates of software cost had relatively little impact. Today, software is the most expensive element in many computer-based systems. Therefore, steps taken to reduce the cost of software can make the difference between the profit and loss of a company. So, by determining the quality attributes of software, more precise, predictable and repeatable control over the software development process and product will be achieved. We propose a formal approach from the problem oriented software engineering point of view, for estimating the reliability of a software package by determining the error rate.

quality. Aspect oriented software development is a new paradigm that claims to improve the quality of software using separation of concerns. In this paper we show how the aspect oriented paradigm has evolved from the object oriented paradigm, giving definitions of key aspect oriented terms to aid comprehension and
clarification. We then show how techniques involved
in aspect oriented design can help to improve software quality.
