An important problem faced by many Computer Science and Software Engineering programs is declining enrollment. In an effort to reverse that trend at Mississippi State University, we have instituted pair programming for the laboratory exercises in the introductory programming course. This paper describes a study performed to analyze whether using pair(More)
Inspection is considered a powerful method to check software documents for defects. Many published work shows that inspections in requirements specification phase are particularly effective and efficient. Perspective-Based Reading (PBR) is one of the systematic techniques to support defect detection in requirements documents. In this paper we describe an(More)
An annual investigation into the abundance of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in fresh water aquaculture ponds was performed by quantitative PCR of the amoA gene. The results showed that AOB were the main ammonia-oxidizing microorganisms in water, and significantly higher copy numbers of the AOB amoA gene were observed(More)
Despite the critical role of software modifiability, it has no universally accepted measurement model. Measuring modifiability in terms of maintenance effort is problematic because it confounds modifiability with the ability of individual maintainers. In this paper, we apply Wood's task complexity model to propose a general analytical model that describes(More)
We present a novel, computationally efficient approach for natural image segmentation that uses the adaptive clustering algorithm (ACA) to obtain an initial segmentation and chrominance-based region merging to consolidate regions of perceptually uniform texture. The combination of ACA and chrominance-based merging preserves salient edges and smooths out(More)
