The object-oriented class is, in general, the most utilized element in programming and modeling. It is employed throughout the software development process, from early domain analysis phases to later maintenance phases. A class diagram typically uses elements of graph theory, e.g., boxes, ovals, lines. Many researchers have examined the class diagram layout from different perspectives, includin...

Using the concept of nullors, an unified methodology is presented which can be used for realizing fully differential current mode filters using a variety of building blocks which can be represented by nullators and norators. The workability of the proposed approach is verified by the SPICE simulation results of an exemplary universal biquad made from multiple-output-currentconveyors. This exemp...

We describe a system that automatically extracts biological events from biomedical journal articles, and translates those events into Biological Expression Language (BEL) statements. The system incorporates existing text mining components for coreference resolution, biological event extraction and a previously formally untested strategy for BEL statement generation. Although addressing the BEL ...

There is general consensus in the software literature that real-time systems are difficult to model, specify, and design. It is an important and challenging task to develop an intuitive and easyto-use, yet coherent and concise method for specifying such systems. The Object-Process Methodology (OPM) graphically specifies systems in a single unified model that describes the staticstructural and b...

This paper is focused on analysing the complete business environment with the help of information technology. It takes into account various interactions between different business processes while conducting BPR exercise. It also provides a framework based on event diagrams to record logical flow and other relevant details, which can be used for design of an information system. The event diagram...

Checking of web accessibility can be carried out in several ways along the same international standards. The evaluation methodologies used by evaluation and certification organizations in several European countries (such as AccessiWeb in France, Technosite in Spain and AnySurfer in Belgium) are different in subtle but meaningful ways, even though they are usually based on the Web Content Access...

The teaching of digital design requires a design platform which presents a coherent design methodology to the students. Yet we found ourselves with diflerent tools and hardware subsystems, each having its own idea about what digital design was about. Here we record our eflort t o forge a single design platform for beginning designers from three separate software subsystems and two hardware subs...

This paper presents a method to compute metrics that predict maintainability of a system with respect to its event processing. The metrics reflect the complexity of event dependencies in an object-oriented system. They can be computed from a UML design or from a program code. The maintainability factor is obtained by comparing the calculated metrics with the metrics for a design conforming to a...

Die Software-Produktlinienentwicklung erlaubt die Entwicklung ähnlicher Software-Systeme zu geringen Kosten, in kurzer Zeit und zudem mit steigender Qualität. Zahlreiche Erfahrungen aus der Industrie belegen diese Vorteile der Produktlinienentwicklung gegenüber der Entwicklung von Einzel-SoftwareSystemen. Der Schlüssel für die Software-Produktlinienentwicklung ist die Unterscheidung zwischen zw...

Design patterns are reusable proven solutions to frequently occurring design problems. To encourage software engineers to use design patterns effectively and correctly throughout the development process, design patterns should be classified and represented formally. In this paper, we apply Object Process Methodology (OPM) for representing and classifying design patterns. OPM enables concurrent ...
