A meshless local Petrov-Galerkin method (MLPG) based on the moving Kriging interpolation for elastodynamic analysis is presented in this paper. The present method is developed based on the moving Kriging interpolation for constructing shape functions at scattered points, and the Heaviside step function is used as a test function in each subdomain to avoid the need for domain integral in symmetric weak form. Since the shape functions constructed by this moving Kriging interpolation have the delta function property, the essential boundary conditions can be implemented easily, and no special treatment techniques are required. The discrete equations of the governing elastodynamic equations for two-dimensional solids are obtained using the local weak-forms. The Newmark method is adopted for the time integration scheme. Some numerical results are compared to that obtained from the exact solutions of the problem and other (meshless) methods. This comparison illustrates the efficiency and accuracy of the present method for solving the static and dynamic problems. © 2013 Imperial College Press. Source

Cloud computing is the fundamental change happening in the field of Information Technology. It is a representation of a movement towards the intensive, large scale specialization. On the other hand, it brings about not only convenience and efficiency problems, but also great challenges in the field of data security and privacy protection. Currently, security has been regarded as one of the greatest problems in the development of Cloud Computing. This paper describes the great requirements in Cloud Computing, such as security key technology, standard and regulation etc., and discusses ways in which they may be addressed. © 2014 IEEE. Source

Complex networks are everywhere. A typical example is software network. How to measure and control coupling interactions of software components is a largely explored research problem in software network. In terms of graph theory and linear algebra, this paper investigates a pair of coupling metrics to evaluate coupling interactions between the classes of object-oriented systems. These metrics differ from the majority of existing metrics in three aspects: Taking into account the strength that one class depends on other ones, reflecting indirect coupling, and distinguishing various coupling interaction. An empirical comparison of the novel measures with one of the most widely used coupling metrics is described. Specifically, an experiment about the relationships of this pair metrics is conducted. The result shows that software complexity derived from coupling interaction could not be accurately reflected by one dimension of coupling metric for negative correlation. © 2011 Institute of Systems Science, Academy of Mathematics and Systems Science, CAS and Springer-Verlag Berlin Heidelberg.

In this paper, a discrete mathematical model of a magnetic electrospinning process is established and used to analyze numerically the effect of excitation current on electrospinning instability. The charged jet is assumed to be discrete electrified particles, which are joined by viscous flexible materials. The simulation results agree well with the experimental data and show that the magnetic approach provides an effective way to control instability. © 2010 Elsevier Ltd. All rights reserved. Source

How to understand, manage and control Object-Oriented software complexity is a great challenge for software engineering. Recent research achievements in software engineering introduce complex network theory to explore structural complexity. These achievements emphasize understanding Object-Oriented software system as a whole structure instead of focusing on local codes and behaviors. A common way to define software network is based on static structural properties. However, for real-time is a primary characteristic of software system, and polymorphism, dynamic binding, and the unused codes present in software system, the static structural properties are imprecise as they do not perfectly reflect the actual code taking place among classes. This paper describes the reason that software complexity can precisely measured based on dynamic analysis of systems and refers the means to analyze dynamic characteristic of software system structure as complex network. © 2012 IEEE.
