The use of cloud computing has increased rapidly in many organizations. General firms have already adopted the cloud computing and -services. In addition, government organizations have recently introduced this system, which is gaining more users. The purpose of adopting cloud computing varies, yet the main purposes are to cut the cost, increase the work-efficiency, and ensure more security. The...

For a continuous map on the unit interval or circle, we define bifurcation set to be collection of those holes whose surviving is sensitive arbitrarily small changes (some of) their endpoints. By assuming global perspective and focusing geometric topological properties this rather than sets individual holes, obtain novel invariant for one-dimensional dynamics. We provide detailed description in...

The paper considers a process Zt = (Xt, Yt) where Xt is the position of a particle and Yt its velocity, driven by a hypoelliptic bi-dimensional stochastic differential equation. Under adequate conditions, the process is stationary and geometrically β-mixing. In this context, we propose an adaptive non-parametric kernel estimator of the stationary density p of Z, based on n discrete time observa...
