India has traditionally attached great importance to its relations with Central Asia. But, unfortunately, the relationship faces several constraints including the lack of direct access to Central Asia; the unstable situation in Afghanistan and a problematic IndiaPakistan relation. India and Central Asia: Need for a Pro-active Approach Arvind Gupta Dr Arvind Gupta is Director General at the Inst...

As the most active plateau on the Earth, the Qinghai-Tibet Plateau (TP) has a complex crust–mantle structure. Knowledge of the distribution of such a structure provides information for understanding the underlying geodynamic processes. We obtain a three-dimensional model of the density of the crust and the upper mantle beneath the TP and surrounding areas from height anomalies using the Earth G...

Speech can lead to increased performance in computer-based problem solving. Studies of complex interaction styles — such as command-line or system-delayed interaction — have found that complex interaction styles can lead to savings in the number of actions users take to reach a solution for certain tasks compared with direct manipulation. Speech can be viewed a complex interaction style because...

This paper establishes a direct method for solving variational problems via a set of Radial basis functions (RBFs) with Gauss-Chebyshev collocation centers. The method consist of reducing a variational problem into a mathematical programming problem. The authors use some optimization techniques to solve the reduced problem. Accuracy and stability of the multiquadric, Gaussian and inverse multiq...

Determining the diffusion coefficient based on the solution of the linear inverse problem of the parameter estimation by using the Least-square method is presented. A set of temperature measurements at a single sensor location inside the heat conducting body is required. The corresponding direct problem will be solved by an application of the heat fundamental solution.

In any supply chain, distribution planning of products is of great importance to managers. With effective and flexible distribution planning, mangers can increase the efficiency of time, place, and delivery utility of whole supply chain. In this paper, inventory routing problem (IRP) is applied to distribution planning of perishable products in a supply chain. The studied supply chain is compos...

in this paper we present the problem of designing a three level hub center network. in our network, the top level consists of a complete network where a direct link is between all central hubs.  the second and third levels consist of star networks that connect the hubs to central hubs and the demand nodes to hubs and thus to central hubs, respectively. we model this problem in an incomplete net...
