We mined and manually validated over 12,000 refactoring operations.We verified if refactoring occurs on classes having poor quality as indicated by code metrics.We verified whether refactoring occurs on classes affected by bad smells.With very few ...

Throughout the history of software engineering, the human aspects have repeatedly been recognized as important. Even though research that investigates them has been growing in the past decade, these aspects should be more generally considered.The main ...

A quantitative measurement of "agility" with connected CI to the items.A positive result from practitioners on a quantitative agile measurement.Validation tests of internal consistency and construct validity (negative result).New groups of items, but ...

We propose a model-based approach for the modeling and verification of requirements.We integrate the notion of goal-oriented concepts for the requirements definition of self-adaptive systems.We identify the adaptability features associated with the ...

This research investigates the model based approach to detect infeasible paths.Investigated two patterns and their effects on path infeasibility.Proposed an elegant model-based approach to all infeaspaths for two patterns.Our approach is more effective ...

First, we expose the instance of ER with EM algorithm to integrate different models.We apply ER for HDPD to achieve major performance in terms of response time.Matching instance is compared with BFA, Koosh-TND and Packages-TND algorithms.After the ...

We present a taxonomy of the various types of role-based access control policies proposed in the literature.We propose the GemRBAC model, a generalized model for RBAC.This model includes all the entities required to define the classified policies.We ...

We propose a graph model for solving the service deployment problem on cloud.Our approach considers both communication costs and execution parallelism.Service deployment is transformed into a typical minimum k-cut problem for solution. Cloud computing ...

We propose an automated methodology for noise detection.We assist SAR approaches to identify classes that obscure the system structure.We do not require a user defined threshold for noise detection.Our approach performs well in both complex and ...

Cyber-foraging is a technique to extend computing power of mobile devices.We conducted an SLR of architectures for cyber-foraging systems.Common design decisions were codified into architectural tactics for cyber-foraging.Functional tactics are ...

Load-balancing algorithms play a key role in improving the performance of distributed-computing-systems that consist of heterogeneous nodes with different capacities. The performance of load-balancing algorithms and its convergence-rate deteriorate as ...

We show how a large-scale empirical study using Grounded Theory has been used to study Agile transition and adoption process.An empirically-developed transition framework to facilitate Agile transformation is proposed.We describe the key structural ...
