This paper presents the PC-based LabVIEW as a software to develop the algorithm of the robust complex extended Kalman filter (rCEKF) for detection of the parameters of voltage signal in power systems. The hardware of this paper is to take sample-and-hold card and dAQ (data Acquisition) card for extracting the datum from the outside system to the PC, and the program compute the amplitude, frequency, and phase of the voltage signal with rCEKF. For validating the performance of rCEKF in this paper, the voltage signal from function generator is applied to check the feasibility of algorithm firstly, and then this application was also used in the TPC (Taiwan Power Company) secondary substation in Sijhou, Taiwan. © 2010 ISArOB.

S-Mesh: a Mesh-based on-chip network with separation of control and transmission

The current network-on-chip （NoC） topology cannot predict subsequent switch node status promptly. Switch nodes have to perform various functions such as routing decision, data forwarding, packet buffering, congestion control and properties of an NoC system. Therefore, these make switch architecture far more complex. This article puts forward a separating on-chip network architecture based on Mesh （S-Mesh）, S-Mesh is an on-chip network that separates routing decision flow from the switches. It consists of two types of networks： datapath network （dN） and control network （CN）. The CN establishes data paths for data transferring in dN. Meanwhile, the CN also transfers instructions between different resources. This property makes switch architecture simple, and eliminates conflicts in network interface units between the resource and switch. Compared with 2d-Mesh, Toms Mesh, Fat-tree and Butterfly, the average packet latency in S-Mesh is the shortest when the packet length is more than 53 B. Compared with 2d-Mesh, the areas savings of S-Mesh is about 3%-7/% and the power dissipation is decreased by approximate 2%.

Implementing the dynamic couple of searching paths and resource allocation becomes increasingly important in the research of Quality of Service (QoS) routing. In this paper, we formulate the problem of dynamic QoS routing with resource allocation based on Worst-case Fair Weighted Fair Queuing (WF 2Q) packet scheduling style. We propose an algorithm using the proved results - the optimal path resource allocation algorithm (OPrA2), which can allow intelligent choice of the maximized reliability and minimized delay path according to the types of applications and adapt QoS parameters and allocated resources related to WF2Q in process of routing. It can find an optimal path which satisfies different QoS requirements and compute the amount of bandwidth and buffer resources needed at each node. We provide the simulation results to illustrate the effect of buffers and bandwidths according to the values of control parameters. © 2009 IEEE.

Current MSM switching fabric has poor performance under unbalanced traffic. This paper presents an alternative, novel Central-stage Buffered Three-stage Clos switching (CB-3Clos) fabric and proves that this fabric can emulate output queuing switch without any speedup. By analyzing the condition to satisfy the central-stage load-balance, this paper also proposes a Central-stage Load-balanced-based distributed Scheduling algorithm (CLdS) for CB-3Clos. The results show that, compared with Concurrent round-robin based dispatching (Crrd) algorithm based on MSM, CLdS algorithm has high throughput irrespective with the traffic model and better performance in mean packet delay.

This paper proposes a model of dam-breach problems for Tangjiashan quake lake which had been threatening to breach its dam and wash away people downstream. The proposed model utilizes the theories of flow dynamics and overflowing dam-break to solve the issues of discharge and expansion of the crevasse, and evolution of the dam-breach flow. The simulation results show that our model can perform close to the reality in terms of draining the Tangjiashan quake lake. ©2009 IEEE.

Multi-nexthop routing Mechanisms is the key point in network congestion, and the essential question is how to forward packets among Multi-nexthop to reach equiponderant forwarding. This paper proposes an equiponderant forwarding strategy in Multi-nexthop routing, which forwards the packets according to the actual capability of each node, and resolves the equiponderant forwarding problem of Multi-nexthop. The simulation results indicate that this strategy can realize the equiponderant forwarding of multi interfaces, and make the flux of whole network also equiponderant. © 2009 IEEE.

The number of users accepted by a cell is limited by the total received interference power at base station transceiver in code-division multiple access (CdMA) system. In this paper, we propose a received power based call admission control (MSrP-CAC) scheme supporting multi-class services for uplink, which determines the admission of multi-class services via presetting power allocation ratios. The improved scheme is investigated and its performance is compared with simple scheme. Simulation results show that the improved scheme can guarantee the QoS of different traffic adaptively and improve the resources utilization. ©2009 IEEE.

The Counting Bloom Filter （CBF） is a kind of space-efficient data structure that extends a Bloom filter so as to allow approximate multiplicity queries on a dynamic multi-set. This paper evaluates the performance of multiplicity queries of three simple CBF schemes-the Naive Counting Bloom Filter （NCBF）, the Space-Code Bloom Filter （SCBF） and the d-left Counting Bloom Filter （dlCBF）-using metrics of space complexity and counting error under both uniform and zipfian multiplicity distributions. We compare their counting error under same space complexity, and their space complexity when similar counting errors are achieved respectively. Our results show that dICBF is the best while SCBF is the worst in terms of both space-efficiency and accuracy. Furthermore, the performance gap between dlCBF and the others has a trend of being enlarged with the increment of space occupation or counting accuracy.
