Calcium is a vital second messenger used in signal transduction. Calcium controls secretion, cell movement, muscular contraction, cell differentiation, ciliary beating and so on. Two theories have been used to simplify the system of reaction-diffusion equations of calcium into a single equation. One is excess buffer approximation (EBA) which assumes that mobile buffer is present in excess and c...

Future space missions are envisioned to be implemented using a flexible, distributed architecture consisting of constellations of dynamically deployed or configured space and mobile platforms that are networked together into an integrated information system, which we term an ad hoc space network. An ad hoc space network is characterized by changing topology and potentially sparse and intermitte...

Most people in Europe live in urban environments. For these people, urban green space is an important element of well-being, but it is often in short supply. We use self-reported information on life satisfaction and different individual green space measures to explore how urban green space affects the well-being of the residents of Berlin, the capital city of Germany. We combine spatially expli...

A Video-on-Demand system (VoD) [1] integrates the entertainment, telecommunication, and computer industries and provides electronic video rental services to geographically dispersed users from remote video servers on a broadband network. Several techniques have been proposed to increase the number of concurrent viewers of popular movies through better usage of resources. One technique uses the ...

The multipath protocol AOMDV is removes the limitation of alternative path and balance the load more efficiently. In this research the proposed scheme firstly, introduces a redundant multipath routing strategy, which establishes and maintains multiple backup routes from the source and intermediate node to the destination node and increment the buffer space of nodes with very low routing overhea...

Unlike to traditional hierarchical and partitional clustering algorithms which always fail to deal with very large databases, a neural network architecture, Projective Adaptive Resonance Theory (PART), is developed for the high dimensional space clustering. However, the success of the PART algorithm depends on both accurate parameters and satisfied orders of input data sets. These disadvantages...

Calcium is very important for communication among the neurons. It is vital in a number of cell processes such as secretion, cell movement, cell differentiation. To reduce the system of reactiondiffusion equations of [Ca] into a single equation, two theories have been proposed one is excess buffer approximation (EBA) other is rapid buffer approximation (RBA). The RBA is more realistic than the E...
