A large portion of area and power in Network-on-Chip (NoC) routers is consumed by buffers, and hence these costly storage resources must be utilized well. However, some early related literatures are not suitable for modern NoC router architecture as well as various complicated traffic loads anymore. In this work, we first revisited the original dynamically-allocated multi-queue (DAMQ) buffer schem... View full abstract»

Designing embedded systems has become a challengingprocess due to the increasing complexity of the applications. In addition, there is a need to meet multiple conflicting constraints such as speed, power and cost. These factors have led to an explosion in the design space as each task in the application can have various implementation options (software and a range of hardware customizations), wher...

We propose a new fault-tolerant (self-stabilizing) distributed framework for the publish/subscribe scheme in a P2P network, where the participating nodes (peers) only need the state information of its immediate neighbors. The proposed system is guaranteed to recover from an unlimited number of transient faults (e.g., state corruption). We provide a complexity analysis of the recovery (stabilizatio...

A runtime framework for GPGPU is proposed. It provides a unified interface for applications to easily take advantage of the various computation powers on a heterogeneous environment. Multiple devices and platforms, such as CUDA and OpenCL can be utilized at the same time to achieve a better performance. View full abstract»

In this paper, we propose a sensitive and robust reputation system for service grid environments. A punishment factor is introduced to express the subjective opinion of evaluators and destroy the reputation of bad performers rapidly, which improves the sensitivity of the reputation system. By evaluating the reputation of recommenders, our solution filters out dishonest recommendations during the p... View full abstract»

In this paper the efficient mapping of pipeline single path delay feedback (SDF) fast Fourier transform (FFT) processors to FPGAs is considered. By paying special attention to how the design can efficiently be mapped to the course grained hardware structure of a target field programmable gate array (FPGA) better implementation results can be obtained.This is illustrated by mapping a R22 SDF FFT pr...

The induction motor parameters vary with the operating conditions considerably in the Hybrid Electric Vehicle. The induction motor drive cannot deliver high static and dynamic performance without the correct machine parameter values in the controller. Therefore, an online multi-parameter identification technique for induction motor is necessary. In this paper, a novel Luenberger-sliding mode obser... View full abstract»

With the increasingly complex power system, wide area protection, using global data obtained from different substations through communications, has been a hot research topic for some time. However, the overall transmission of large amounts of data will cause communication network congestion, which will lead to delay and loss of data. Therefore building an algorithm which can make use of a reduced ... View full abstract»

With deeper research of wind key technologies, concern on operation of a micro-grid with wind power has been aroused greatly. Fully use of supply resources and demand resources of a micro-grid is determined by optimal planning of integrated resources. Considering that implementation of demand-side management is available to change the load profiles and decrease the variation extent of load during ... View full abstract»

The electricity consumption of a charging station is obviously fluctuant. An energy storage system is an effective device to improve the load variation of the charging station. In order to give full play to energy storage system, this paper proposes a charging and discharging control strategy of the storage system considering multi-objective including stabilizing load and economizing electric cons...

This paper presents a simple and effective approach to improve dependency parsing by exploiting multiple feature-sets. Traditionally, features are extracted by applying the feature templates to all the word pairs(first-order features)and word tuples(second-order features). In this pa per, we show that exploiting different feature templates for different word pairs and word tuples achieves signific... View full abstract»

Document clustering is a significantly popular research, which aims to partition a corpus into many subgroups of homogeneous documents. Traditional clustering approaches catholically lack of considerations of word weights with clusters. To address this problem, we propose an Adaptive Centroid-based Clustering (ACC) algorithm. As a successful supervised centroid-based classifier, Class-Feature-Cent... View full abstract»
