A concept lattice based approach for analysis of class cohesion is presented. The approach facilitates rapid identification of less cohesive classes. It also helps identify less cohesive methods, attributes and classes in one go. Further, the approach guides refactorings such as extract class, move method, localize attributes and remove unused(More)
Parallel computing on interconnected workstations is becoming a viable and attractive proposition due to the rapid growth in speeds of interconnection networks and processors. In the case of workstation clusters, there is always a considerable amount of unused computing capacity available in the network. However, heterogeneity in architectures and operating(More)
In the conventionalobject model, encapsulatedobjects interact by messages that result in method invocations on the destination object. A message is delivered directly at the destination object. As a result of the direct deliveries, the message control code performing intermediate message manipulations cannot be abstracted out separately from the message(More)
Maintenance downtime and overheads for applying patches are major concerns for systems requiring round the clock availability. Hence, methods for carrying out dynamic updates are needed. However, correctness of the system during and after every dynamic update needs to be ensured. This paper defines two safety criteria, type consistency and isolation of(More)
A UML based metamodel for Bunge-Wand-Weber (BWW) ontology is presented. BWW ontology is a generic framework for analysis and conceptualization of real world objects. It includes categories that can be applied to analyze and classify objects found in an information system. In the context of BWW ontology, the metamodel is a representation of the ontological(More)
In this article, I identify filter configurations based on filter objects for OO distributed systems. The configurations are based on the notion of first class filter objects that transparently intercept messages in a client-server object architecture. Transparency primitives for filtering are described and various filter configurations are illustrated(More)
Two new types of structure-related molecular descriptors, JMn and JSn, have been developed using conformational energies from quantum chemical calculations. For this purpose propipocaine (CAS 3670-68-6) was chosen as a model and 42 analogues were studied. The quantum chemical calculations were performed applying AM1 and PCILO approximation methods.(More)
It is observed that most object oriented coupling metrics are macroscopic, which makes them unsuitable for making finer refactoring decisions. The notions of microscopic viewpoints and coupling projections are introduced. Existing metrics are classified in terms of viewpoints and projections. Two microscopic metrics called relative method coupling (RMC) and(More)
Weyuker's Property 9 has received a mixed response regarding its applicability to object oriented software metrics. Contrary to past beliefs, the relevance of this property to object oriented systems is brought out. In support of the new argument, counterexamples to earlier claims are formulated and two new metrics highlighting a notion of complexity that(More)
