The feature model is a domain/product-line oriented requirements model based on hierarchical structure and explicit variability modeling, and has been adopted by several important software reuse methods. However, with respect to the problem of verification of constraints on features and verification of partially customized feature models, these methods tend(More)
Model Transformation is a crucial part of Model-Driven Architecture (MDA). However, most of the current researches only focus on the transformation from PIM to PSM, and pay little attention to the CIM-to-PIM transformation. One of the results is that converting CIM to PIM will depend much on designers' personal experience or creativity, and thus the(More)
In the research of software reuse, feature models have been widely adopted to organize the requirements of a set of applications in a software domain. However, there still lacks an effective approach to minimizing analysts' participation in feature models' construction. In this paper, we propose a use case based semi-automatic approach to the construction(More)
Computation offloading is a promising way to improve the performance as well as reducing the battery power consumption of a smartphone application by executing some parts of the application on a remote server. Supporting such capability is not easy for smartphone application developers due to (1) correctness: some code, e.g., that for GPS, gravity, and(More)
