An approach for tight coupling of process models and software development tools — with the metaphor of component-based software development environments — supporting “eXecutable Process Models” (XPM) is presented. In this paper, we focus on the direction from the components of a software development environment towards the process models in order to automatically acquire process model informati...

Classes are not the best focus for object-oriented design. The most useful components in a design are frameworks – schemes of interaction between objects. These can be worked on by separate authors, kept in libraries, and recombined to make many different end-products. This paper explores the more formal aspects of this approach, within the context of popular OOA/D notations and programming lan...

This paper presents P-RIO, a parallel programming environment that supports an object based software conjiguration methodology. It promotes a clear separation of the individual sequential computation components from the interconnection structure used for the interaction between these components. This makes the data and control interactions explicit, simpliJjiing program visualization and unders...

In today’s computing environments every user interacts with several dozens of highly heterogeneous devices. These devices are frequently arranged in contexts; in any given context the user is interacting with a specific set of devices. Context oriented data staging is the problem of delivering up-to-date data to the devices of the current context, following the movement of the user between the ...

We present a semi-automatic solution to the problem of customized 3-D shape modeling using a rule based system. The solution is illustrated with the use case of hearing aid manufacturing. The current process of manufacturing customized hearing aids consists of many manual steps, all of which require expert knowledge. The idea is to translate this expert knowledge into machine readable rules usi...

The mobile nodes in MANETs dynamically change their topology and hence require an efficient mechanism to communicate with each other. There are number of routing protocols anticipated for MANET environment categorized as Location based routing protocols and Non-Location based routing protocols. In MANETs, Location based routing protocols are preferred as they are more efficient in routing compa...

This chapter describes the development and deployment of the credit assistant (CA), a knowledge-based system to support credit operations for Travel-Related Services (TRS) of the American Express Company. CA was developed using ART-IM, a rule-based programming environment from Inference Corporation. American Express developed this application under a UNIX environment (SUN and RS/6000) and deplo...

Component reuse is widely considered vital for obtaining significant improvement in development productivity. However, as an organization adopts a reuseoriented development process, the nature of the problems in development is likely to change. In this article, we use a measurement-based approach to better understand and evaluate an evolving reuse process. More specifically, we study the effect...

The Problem: The idea of ubiquitous a computing environment where sensors and devices exist everywhere around us has opened up interesting security and privacy issues. Imagine a scenario in which Ben is working in an intelligent room. He does not want to be disturbed by anyone, so he tells the intelligent room that he does not want to be reached by anyone in the next two hours unless it is an e...

In these years, grid computing is probably the most promising approach for building large scale and cost effective applications. However, this very popular approach needs a sophisticated software infrastructure to address several requirements. One of these requirements is the ability to sustain a predictable performance in front to the fluctuations related to the dynamic nature of a grid. In th...
