Nowadays, the great benefits of cloud computing have dramatically increased the number of e-banking users. Hence, the competition in the banking industry has boosted and managers need to evaluate their branches on a regular basis. To this end, this study aims to evaluate cloud-based banking systems based on the Quality of Service (QoS) attributes using the Dynamic Network Data Envelopment Analy...

The conformal barycenter of a point cloud on the sphere at infinity Poincare ball model hyperbolic space is analogue geometric median in Euclidean space. It was defined by Douady and Earle as part construction conformally natural way to extend homeomorphisms circle disk, it plays central role Millson Kapovich's configuration cyclic linkages with fixed edgelengths. In this paper we consider pr...

Deadline-sensitive workflows require careful coordination of user constraints with resource availability. Current distributed resource access models provide varying degrees of resource control: from limited or none in grid batch systems to explicit in cloud systems. Additionally applications experience variability due to competing user loads, performance variations, failures, etc. These variati...

We employ the first fully three-dimensional simulation to study the role of magnetic fields and ion-neutral friction in regulating gravitationally-driven fragmentation of molecular clouds. The cores in an initially subcritical cloud develop gradually over an ambipolar diffusion time while the cores in an initially supercritical cloud develop in a dynamical time. The infall speeds on to cores ar...

In this paper we take the point of view that there is a formalism for modeling a within-day dynamic user equilibrium (DUE) that is an extension of traditional differential game theory to accomodate the natural formulation of DUE as an infinite dimensional differential variational inequality (DVI) involving explicit state-dependent time shifts, explicit control variables and explicit equations o...

The first part of the present paper is devoted to a systematic construction of continuous-time finite-dimensional integrable systems arising from the rational su(2) Gaudin model through certain contraction procedures. In the second part, we derive an explicit integrable Poisson map discretizing a particular Hamiltonian flow of the rational su(2) Gaudin model. Then, the contraction procedures en...

Abstract   The present paper is devoted to implementation of the immersed boundary technique into the Fourier pseudo-spectral solution of the vorticity-velocity formulation of the two-dimensional incompressible Navier-Stokes equations. The immersed boundary conditions are implemented via direct modification of the convection and diffusion terms, and therefore, in contrast to some other similar ...
