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)
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)
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)
Shared caches in chip multi-processors (CMPs) have important benefits such as accelerating inter-core communication, yet the inherent cache contention among multiple processes on such architectures can significantly degrade performance. To address this problem, cache partitioning has been studied based on the prediction of the cache miss rate curve (MRC) of(More)
Recent years have witnessed a rapid growth in using Web services for data publishing and sharing among organizations. To improve the efficiency of software development and economize on human and material resources, service reuse is viewed as a powerful means which will not only reuse atomic services, but also reuse arbitrary granularities of Service Process(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)
The ebXML registry & repository standard is one of the most well accepted standards in the field of registry. Several products claiming to be ebXML compatible [Sun Microsystems, Korea Institute of eCommerce, Korea Trade Network, XML Global] have been developed. While the ebXML standard is initially designed for registering and storing e-business related(More)
Blue algal blooms are constantly observed in Taihu Lake in recent years. Firstly, a two-dimensional hydrodynamic model and drogue tracking method are validated and possible blue algal blooms initiated at Gonghu are studied to find out how wind conditions affect blue algal blooms in Gonghu. Then, surface drogue tracking experiments are performed for blue(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)
