We show how WeCoTin, an academic prototype product configurator originally designed for non-software products, can be used to create and edit feature models of software product lines. Further, we show that WeCoTin enables the easy configuration of software product lines, i.e., generating descriptions of valid products in the product line.

Variation management in a software product line is a multi-dimensional configuration management problem. In addition to the conventional configuration management problem of managing variation over time, software product lines also have the problem of managing variation among the the individual products in the domain space. In this paper, we illustrate how to “divide and conquer” the variation m...

The present study attempts to investigate the relationship between spatial configuration changes of Qom and the central core in the last half century. The main objective of this study is to review the Spatial form of Qom, and analyze the effect of changes in Urban configuration on the central core of the city and the main axes of urban activities during 1946 to 2011 and ultimately, Forecast the...

Software product Line (SPL) is an emerging methodology for developing software products. Stage-configuration is one the important processes applying to the SPL. In stage-configuration, different groups and different people make configuration choices in different stages. Therefore, a successful software product is highly dependent on the validity of stage-configuration process. In this paper, a ...

Abstract The flexomagnetic effect involves the coupling of inhomogeneous mechanical and magnetic excitations to generate exotic spin orders. intrinsic edge stress associated with lifting periodic degeneracy at surfaces or edges in nanostructures facilitates flexocoupling effects. Here, we combine first-principles calculation Maximum Information Coefficient (MIC) statistics quantitatively reveal...

Product configuration is a key activity of product engineering that regards the constrained combination and parameterization of product line assets as a means to achieve correct software specification. Current product configuration approaches frequently rely on the application engineer to translate user requirements into correct configuration choices. This process is error-prone and risky as re...

 In the preset study, the performance of a solar assisted heating, ventilation and air conditioning (HVAC) system in an operating theater building was studied. The yearly performances of the existing HVAC system and the system with the added solar collectors were simulated in terms of energy consumption and provided air conditions using a transient system simulation software (TRNSYS). In t...

It is well known that path planning for robots with many degrees of freedom is a complex task. That is the reason why the research on this area has been mostly restricted to static environments. This paper presents a new method for on-line path planning for robotic arms in dynamic environments. Most on-line path planning methods are based on local algorithms that end up being inefficient due to...
