This paper describes an improved integrated Object Oriented metrics for the high-level design quality assessment of Object Oriented codes. A single class based metrics (a Weighted Class Complexity, WCC) has been proposed that may be used for cumulative measure of all aspects of object oriented design (encapsulation, inheritance and polymorphism), and hence an indication of quality of class in t...

Multiversioning of objects in an object-oriented system provides increased concurrency and enhanced reliability. The last decade has seen proposals for managing transactions in multiversion database systems. We propose a model and an architecture that exploit multiple versions in object-oriented systems. Our architecture contains three main components that ensure correct concurrent serializable...

agent oriented software engineering (aose) is an emerging field in computer science  and  proposes some systematic ideas for multi agent systems analysis, implementation and maintenance. despite the various methodologies introduced in the agent-oriented software engineering, the main challenges are defects in different aspects of methodologies. according to the defects resulted from weaknesses ...

Planning budget will help to identify wasteful expenditures, adapt financial situation changes quickly, and achieve financial goals. The reliability based budgeting has a great importance for broadcasting industry. In this study, several kinds of failure modes in TV broadcasting system have been det...

With respect to the long-life missions associated with NASA’s X2000 Advanced Deep-Space System Development Program, reliability implies a system’s continuous operation for many years in an unsurveyed radiation-intense environment. Further, the stringent constraints on the mass of a spacecraft and the power on-board create unprecedented challenges on the means for achieving the ultra-high missio...
