We introduce the "$type{lffs}$ subdirect product" and show that every ring is uniquely a $type{lffs}$ subdirect product of a family of $simple{basicls}$ rings. Also we show some applications.

In this paper, indirect collocation approach based on compactly supported radial basis function (CSRBF) is applied for solving Volterra's population model. The method reduces the solution of this problem to the solution of a system of algebraic equations. Volterra's model is a nonlinear integrodifferential equation where the integral term represents the effect of toxin. To solve the problem, we use the wellknown CSRBF: $Wendland_{3,5}$. Numerical results and residual norm ($R(t)^2$) show good accuracy and rate of convergence.

The paper is an attempt to represent a study of limit points, boundary points, exterior points, border, interior points and closure points in the common generalized topological space. This paper takes a look at the possibilities of an extended topological space and it also considers the new characterizations of dense set.

In this manuscript, we consider the inverse problem for non selfadjoint SturmLiouville operator $D^2+q$ with eigenparameter dependent boundary and discontinuity conditions inside a finite closed interval. We prove by defining a new Hilbert space and using spectral data of a kind, the potential function can be uniquely determined by a set of value of eigenfunctions at an interior point and part of two sets of eigenvalues.

The Cloud Computing model leverages virtualization of computing resources allowing customers to provision resources ondemand on a payasyougo basis. During recent years, the power consumption of datacenters in cloud environment attracted researchers. Optimization of energy consumption can be performed by different methods including virtual machine (VM) consolidation. This technique can reduce energy consumption by preventing of wasting them. Also, VM migration can provide opportunity to reduce energy consumption. In this article, we want to study different methods and policies to select and place VMs and migration algorithms for underutilized and overutilized servers in order to reduce energy consumption and SLA violation. We offer general and comprehensive framework on optimization of VM consolidation as its owchart and at last, suggest combined idea to detect underloaded and overloaded hosts and also VM selection and VM placement policies.

In this paper, we define Xslant helix in Euclidean 3space and we obtain helix, slant helix, clad and gclad helix as special case of the Xslant helix. Then we study Darboux, tangential darboux developable surfaces and their singular points. Especially we show that the striction lines of these surfaces are singular locus of the surfaces.
