It is inadequate to just assure the functional requirements. Quality of service (QoS) must also be satisfied. An important challenge for developing efficient Service Oriented Architecture (SOA) is to maintain the QoS attributes because of compositional and dynamical environment of SOA. It is significant to scrutinize how quality attributes are supported by SOA. However, implementation of SOA pr...

Metadata is the key to component-based programming. Metadata can provide additional information for every type and member defined in the program code in a languageneutral fashion. Moreover, metadata facilitates the interaction of a component with another component or application. In this position paper, we analyze the expressive power of custom attributes, one of the most innovative features of...

Knowledge of the association information between the attributes in a data set provides insight into the underlying structure of the data and explains the relationships (independence, synergy, redundancy) between the attributes. Complex models learnt computationally from the data are more interpretable to a human analyst when such interdependencies are known. In this paper, we focus on mining tw...

SOA enables integration of applications and resources flexibly, representing every application or resource as a service. Its purpose is to facilitate reuse and interoperability of applications, which are regarded as quality attributes of a system. It is very easy to talk about the benefits of SOA (reuse, etc.). But, there are no precise specifications to define this concept as the architectural...

Although schemes for incremental semantic evaluation have been explored and refined for more than two decades, the demands of user interaction continue to outstrip the capabilities of these schemes. The feedback produced by a semantic evaluator must support the user's programming activities: it must be structured in a way that provides the user with meaningful insight into the program (directly...

Facilitating effective distance learning interaction depends on the use of current technologies. Substantiated technology integration strategies are needed for distance educators to make informed choices about technologies as well as learning goals. Technology attributes and pedagogical factors that contribute to distance learning interaction are discussed. The purpose of this work is to provid...

The interaction protocols of software components are critical to their proper understanding and use. In this paper, we introduce a temporal logic based approach to the specification of component interaction protocols. The protocol specifications take the form of interaction constraints on a component’s signature elements (i.e., attributes, operations and events). In particular, this approach al...

Color is commonly described in terms of the three perceptual attributes-hue, saturation, and brightness-of which only hue has a qualitative nature, saturation and brightness being of a quantitative nature. A possible reason for such a phenomenological structure of the color manifold, and its geometric representation, are discussed.
