The continuing increase of interest in Componentbased Software Engineering (CBSE) signifies the emergence of a new development trend within the software industry. Unlike preceding software engineering models, CBSE heavily relies on the utilization of commercial off-the-shelf (COTS) products as the underlying foundation for new product development. Its emphasis is on the identification, selectio...

This paper presents a methodology of mapping population-centric social, infrastructural, and environmental metrics at neighborhood scale. This methodology extends traditional survey analysis methods to create cartographic products useful in agent-based modeling and geographic information analysis. It utilizes and synthesizes survey microdata, sub-upazila attributes, land use information, and gr...

Workflows provide an expressive programming model for fine-grained control of large-scale applications in distributed computing environments. Accurate estimates of complex workflow execution metrics on large-scale machines have several key advantages. The performance of scheduling algorithms that rely on estimates of execution metrics degrades when the accuracy of predicted execution metrics de...

The growing trend towards running publish/subscribe (pub/sub)-based distributed real-time and embedded (DRE) systems in cloud environments motivates the need to achieve end-to-end quality-of-service (QoS) over wide-area networks (WANs). The OMG Data Distribution Service (DDS) is a data-centric middleware that provides fast, scalable and predictable distribution of real-time critical data. The D...

This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

The U.S. military is in the midst of a transformation. While business leaders moved quickly to put computing power in the hands of individuals, the military establishment has been less responsive. Network Centric Warfare is a current U.S. Navy initiative to leverage the power of the computer to restructure forces from the bottom up. Instead of a strict hierarchy where decisions are pushed down,...

This article will argue that, despite customer-centric intent, marketing theory remains trapped in a firm-centric paradigm. How this apparent contradiction has endured is discussed critically with reference to what we see as four influential marketing perspectives. These perspectives are the 4Ps marketing mix, market-based assets, relationship marketing, and customer equity. Apart from the 4Ps ...

introduction: the aim of this study was to investigate whether there is any relationship between the condition of complete dentures and tmds. methods: the sample consisted of 61 consecutive patients (35 females and 26 males) who were admitted to the department of prosthodontics of mashhad faculty of dentistry for fabrication of new complete dentures.  the age range of the participants was betwe...
