Rotorcraft design is challenging with respect to fatigue considering the wide range of loads to which it is subjected. There has been a continuous requirement from the helicopter community in terms of increased flight safety, increased life of components and decreased maintenance and inspection frequency. Structural Health Monitoring (SHM) has definitely catered to this requirement by introduci...

This paper describes the challenges on the requirements engineering for developing an enterprise applications in higher education environment. The development activities include software implementation, maintenance, and enhancement and support for online transaction processing and overnight batch processing. Generally, an enterprise application for higher education environment may include Stude...

Managing software maintenance is rarely a precise task due to uncertainties concerned with resources and services descriptions. Even when a well-established maintenance process is followed, the risk of delaying tasks remains if the new services are not precisely described or when resources change during process execution. Also, the delay of a task at an early process stage may represent a diffe...

In consequence of changing requirements and technological progress, software languages are subject to change. The changes affect the language’s specification, which in turn affects language processors as well as existing language utterances. Unfortunately, little is known about how software languages evolve in practice. This paper presents a case study on the evolution of four modeling language...

Quality software are robust, reliable and easy to maintain, and therefore reduces the cost of software maintenance. But as software systems undergo modifications, improvements and enhancements to cope with evolving requirements, quality of software can be decreased. Refactoring is one of the methods which have been applied to improve software quality. Supporters claim that it helps increasing t...

This paper presents a view of software engineering as it is in 1979. It discusses current software engineering practice with respect to lessons learned in the past few years, and concludes that the lessons are currently not heeded roughly half of the time. The paper discusses some of the factors which may account for this lag, including rapid technological change, education shortfalls, technolo...
