As one of the fundamental infrastructures for cloud computing, data center networks (DCN) have recently been studied extensively. We currently use pure software-based systems, FPGA based platforms, e.g., NetFPGA, or OpenFlow switches, to implement and evaluate various DCN designs including topology design, control plane routing, congestion control. However, approaches suffer from high CPU overhead processing latency; platforms are difficult program incur cost; focuses on functions at...

Solid-state disks (SSDs) are becoming widely used in personal computers and expected to replace a great portion of magnetic servers supercomputers. Although many high-speed SSDs present the market, both design hardware architecture details flash translation layer (FTL) not well known. Meanwhile, systems requiring high-end storages, specially tuned can perform better than generic ones, because applications such environment usually fixed.

Moving target tracking in wireless sensor networks is of paramount importance. This paper considers the problem state estimation for L-sensor linear dynamic systems. Firstly, establishes fuzzy model measurement condition estimation. Then, Generalized Kalman Filter design performed to incorporate novel neighborhood function and motion information, improving with an increasing number active sensors. The proposed selection approach has some advantages time cost. As such, if desired accuracy...

This article studies the distributed secure state estimation problem in unreliable multiagent networks through adversary detection. The agents are endowed with capacity for detecting malicious neighbors and aim to collaboratively estimate variables of a dynamic system presence agents. A trust mechanism is first introduced characterize reliability information received from in-neighbors identify reliable two-hop in-neighbors. With help communication, two schemes detection algorithms developed...

This article deals with the distributed state estimation problem for linear systems in networks cooperative interactions and antagonistic interactions, where are characterized by positive weights negative weights, respectively. Due to coexistence of existing methods based on non-negatively weighted graph become not applicable. First, a partition method nodes decomposition form system matrices introduced. Then new observers is proposed network interactions. Necessary sufficient conditions,...

A novel multi-focus image fusion approach using coupled dictionary training is proposed. It exploits the facts that (i) patches in example data can be sparsely represented by a couple of over-complete dictionaries related to focused and blurred categories images (ii) merging such representations better than just selecting sparsest one estimate original image. Inspired these observations, we enforce similarity sparse between jointly dictionary, then fuse generate an all-in-focus rule. The key...
