Performance Comparison of IP-Networked Storage

Dramatically increasing amounts of digital data are placing huge requirements on storage systems. IP-networked storage systems, such as the network file system (NFS)-based network-attached storage (NAS) systems and the iSCSI-storage area network (SAN) systems, have become increasingly common in today’s local area network (LAN) environments. The emergence of new storage techniques, such as object-based storage (OBS) and content aware storage (CAS), significantly improves the functionality of storage devices ...     

Nonexistence of Positive Solutions to a Quasilinear Elliptic System And Blow—up Estimates for a Non—Newtonian Filtration System

In these years, semilinear reaction-diffusion systems of the Fujita type ut=Δu+vm (A) vt Δ v + un, (x,t) ∈Ω× (0,T), as well as the related elliptic systems with the region Ω Rn RN, m ,n ＞ 1 were studied by a number of authors, The problems concerning (A) include the existence and multiplicity of global solutions, blowing-up, blow-up rates, and blow-up sets, uniqueness and nonuniqueness, etc. For (B) , there are problems such as existence and nonexistence, uniqueness and nonuniqueness, and so on. On the contrary, it seems that little is known about the result for quasilinear reaction-diffusion systems (non-Newtonian filtration systems) and quasilinear elliptic systems, especially about that of blow-up rate estimates for quasilinear reaction-diffusion systems.

Evaluation methods for the autonomy of unmanned systems

Future military and civilian unmanned systems will be extensively used on land,under the sea,in air,and in space.Evaluation of their autonomy is critical to realize the autonomous operation ability of unmanned systems.This paper discussed the basic concepts of autonomy and the significance of autonomy evaluation,and then surveys and describes existing evaluating methods.Based on analyses of key technologies and these technologies’ technical readiness levels,a cobweb evaluation model as a universal evaluation model has been used to evaluate unmanned systems.If the technology warps(aspects of autonomy) and wefts(levels of those aspects) of unmanned systems can be determined for the cobweb model,the model can handle the mutual coupling,high dimensions,and diversity of warp lines.This model potentially has wide application in evaluating various unmanned systems.

Advances in simulated modeling of vibration systems based on computational intelligence

Computational intelligence is the computational simulation of the bio-intelligence, which includes artificial neural networks, fuzzy systems and evolutionary computations. This article summarizes the state of the art in the field of simulated modeling of vibration systems using methods of computational intelligence, based on some relevant subjects and the authors' own research work. First, contributions to the applications of computational intelligence to the identification of nonlinear characteristics of packaging are reviewed. Subsequently, applications of the newly developed training algorithms for feedforward neural networks to the identification of restoring forces in multi-degree-of-freedom nonlinear systems are discussed. Finally, the neural-network-based method of model reduction for the dynamic simulation of microelectromechanical systems (MEMS) using generalized Hebbian algorithm (GHA) and robust GHA is outlined. The prospects of the simulated modeling of vibration systems using techniques of computational intelligence are also indicated.     

A Delay System Approach to Fault Detection Filter of Networked Control Systems

In this paper,the fault detection filter(FDF) design problem for networked control systems(NCSs) with both network-induced delay and data dropout is studied.Based on a new NCSs model proposed recently,an observer-based filter is introduced to be the residual generator and formulated as an H∞-optimization problem for systems with two successive delay components.By applying Lyapunov-Krasovskii approach,a new sufficient condition on stability and H∞ performance is derived for systems with two successive delay ...
