Recently we have witnessed a welcomed increase in the amount of empirical evaluation of Software Engineering methods and concepts. It is hoped that this increase will lead to establishing Software Engineering as a well-deened subject with a sound scientiically proven underpinning rather than a topic based upon unsubstantiated theories and personal belief. For this to happen the empirical work m...

Achieving quality properties for software systems and maintaining them during evolution is challenging. Especially, security properties often degrade during software evolution. This is often not noticed and can lead to monetary loss and serious damage to the company’s image. Approaches for maintaining security properties exist but fail to exploit the knowledge of the architectural design phase....

ÐWhile empirical studies in software engineering are beginning to gain recognition in the research community, this subarea is also entering a new level of maturity by beginning to address the human aspects of software development. This added focus has added a new layer of complexity to an already challenging area of research. Along with new research questions, new research methods are needed to...

ÐExperimentation in software engineering is necessary but difficult. One reason is that there are a large number of context variables and, so, creating a cohesive understanding of experimental results requires a mechanism for motivating studies and integrating results. It requires a community of researchers that can replicate studies, vary context variables, and build models that represent the ...

Practice shows that for current softwa...

A designer often has to evaluate alternative designs during the development of a system. A multitude of Design-Space Exploration (DSE) techniques exist in the literature. Integration of these techniques into the modelling paradigm is needed when a model-driven engineering approach is used for designing systems. To a greater or lesser extent, the integration of those different DSE techniques sha...

closed-end furrows are commonly used to irrigate crop in northern part of china. the irrigation performance of furrow in this area is often low. the objectives of this paper are to verify reliability of infiltration parameters and manning roughness estimated with sipar_id software and present an optimized method for design of closed-end furrow system. the study consisted of field experiments an...
