The concentrations of lead, cadmium, copper, zinc, iron, and mercury in the water, sediment and biota of the Singapore River were determined. The concentration of the various metals in water showed significant variation at different sampling times and there was enrichment of lead content. The spatial patterns of metal distribution in the sediment could be(More)
We consider three level difference replacements of parabolic equations focusing on the heat equation in two space dimensions. Through a judicious splitting of the approximation, the scheme qualifies as an alternating direction implicit (ADI) method. Using the well known fact of the parabolic-elliptic correspondence, we shall derive a two stage iterative(More)
The OER is a comparatively innovative phenomenon which perhaps seen as a part of a bigger movement towards openness in advanced education including more familiar and recognized trends, for example Open Access (OA) and Open Source Software (OSS). This study introduces a web based service for collaborative authoring learning to create, share and explore(More)
Since distributed parallel computing system offers users with more spread computing and storage resources, it provides us a prospect to propose new efficient and dynamic solvers for the numerical solutions of partial differential equations (PDEs) in order to visualize breasts' cancerous cell. Partial differential equations (PDEs) can be classified as(More)
Software birthmark is a unique quality of software to detect software theft. Comparing birthmarks of software can tell us whether a program or software is a copy of another. Software theft and piracy are rapidly increasing problems of copying, stealing, and misusing the software without proper permission, as mentioned in the desired license agreement. The(More)
In this paper, a new algorithm in the class of the AGE method based on the Brian variant (AGEB) of the ADI is developed to solve the heat equation in 3 space dimensions. The method is iterative , convergent, stable and second order accurate with respect to space and time. It is inherently explicit and is therefore well suited for parallel implementation on(More)
Scientific Computing Library Portal (SCLP) is a system for scientific researchers to obtain, contribute, share, store, and analyze scientific algorithm through a portal platform. Due to incomplete existing scientific computing library, not so centralized massive knowledge resources, and distributed data analyses for a science team, it is desired that the(More)
This paper presents the mathematical model for visualizing the active migration glioma growth implemented on distributed parallel computer system. Glioma is the most common type of brain tumor well known as extensively invasive lesions with genetic metabolic abnormalities that contribute to their uncontrolled proliferation and invasion, often leading to(More)
