In recent years, the Software Product Line (SPL) is becoming a mainstream strategy in software development. The high reusability and the great derivability by modelling common and variable artefacts are undoubtedly its significant strengths. Taking advantage of these strengths requires a design of efficient product line. Often, most existing SPL design approaches build on feature modelling by a...

The IT industry started software development by using software components to reduce the efforts, the cost of the product and enhance the productivity and quality of the product. The quality and cost of a software product are highly dependent on the quality and cost of the components assembled to produce the product. There exist a variety of parameters for component selection such as usability, ...

Abstract O ne of the main criticisms of location models is simplistic assumptions concerning the consumers’ distribution on the street or city. The location models usually make use of uniform distribution of consumers while it is not true in reality, and mostly the consumers’ accumulation is more in the city centers rather than suburb areas. This study deals with selectio...

The microstructure and mechanical properties of 7075 wrought aluminum alloy produced by strain induced melt activation (SIMA) route were investigated.Also liquid volume fraction measurement was studied by three procedures. Remelting process was carried out in the range of 560 to 610 °C for 20 min holding. The microstructure in the semi-solid state consists of fine spherical solid grains surroun...
