A low cost control system with hierarchy architecture for sequencer is designed in this paper. A touch screen computer is used as master computer to realize Human Machine Interface (HMI). A programmable logic controller (PLC) works as slave computer to receive sequence ?le and instructions from the master computer. It controls the component arranging, component inspecting, and component taping processes. Manipulating microprocessors work as the slave computers of the PLC. They receive commands from the PLC and control the ampli?ers to drive the rotary electromagnets, which are used to cut off components. A sequence algorithm realized in the PLC is proposed to track the identi?cation (ID) numbers of pallets on the chain. The ID numbers of the pallets are recorded in the PLC at the beginning of sequence procedure, and shifted as long as the movement of the chain. All the ID numbers of the pallets are compared with the ID numbers of component feeders over them. A component is fed into the pallet if its feeder has the same ID number as the pallet. Experimental results verify the validity of the designed control system and the proposed sequence algorithm.

Personal high performance computer (PHPC) requires lower cost and high performance. The Teraflops PHPC systems with special accelerator units like GPGPU have been presented, but they have difficulties in programming, compatibility and applicability. In this paper, we present HPPPHPC, a hybrid architecture of heterogeneous processors connected by non-coherent off-chip system bus. The performance of HPP-PHPC is ensured by special processors integrated with vector units and high-efficiency interconnection between heterogeneous processors. And by the adoption of general processors and features like global physical address space and synchroniz ation semantics in hardware, HPP-PHPC is more compatible and convenient for massage passing and PGAS programming model. Also it is more applicable to most applications, including those with many execution branches. Initial results obtained from our prototype system have proved our design.

This paper presents a system which adopts a standard sequence labeling technique for hedge detection and scope finding. For the first task, hedge detection, we formulate it as a hedge labeling problem, while for the second task, we use a two-step labeling strategy, one for hedge cue labeling and the other for scope finding. In particular, various kinds of syntactic features are systemically exploited and effectively integrated using a large-scale normalized feature selection method. Evaluation on the CoNLL-2010 shared task shows that our system achieves stable and competitive results for all the closed tasks. Furthermore, post-deadline experiments show that the performance can be much further improved using a sufficient feature selection. © 2010 Association for Computational Linguistics

With two auxiliary lines drawn on the racket pad, the intersections of the auxiliary lines and the pad edge are selected as feature points. A simple pose measurement method is designed based on the feature points. A high efficient image-processing algorithm and a feature points extracting method are proposed according to the characteristics of the pad and the auxiliary lines. The racket pose in the camera frame is estimated via PnP positioning approach based on the intrinsic parameters of the camera, the image coordinates of the feature points and their Cartesian coordinates in the racket frame. The experimental results verify the effectiveness of the proposed methods.

As one of the most important enabling technologies of cloud computing, virtualization brings to HPC good manageability, online system maintenance, performance isolation and fault isolation. Furthermore, previous study on VMM-bypass I/O that virtualizes OS-bypass networks (e.g. Infini- Band) relieved the worry of performance degradation coming along with virtualization. In this paper, we address the scalability challenges imposed upon OS-bypass networks under virtualized environments. The eXtended Reliable Connection (XRC) transport, proposed in modern high-speed interconnection networks to address the scalability problem in large scale applications, would not work in virtualized environments. To solve the problem, we propose VM-proof XRC design to eliminate the scalability gap between virtualized and native environments. Prototype evaluation shows that the virtualization of modern high-speed interconnection networks could get the same raw performance and scalability as in native non-virtualized environment with our VM-proof XRC design. The connection memory scalability shows a potential of 16 times improvement on virtualized clusters composed of 16-core nodes. © 2010 IEEE.

Patent classification is a large scale hierarchical text classification (LSHTC) task. Though comprehensive comparisons, either learning algorithms or feature selection strategies, have been fully made in the text categorization field, few work was done for a LSHTC task due to high computational cost and complicated structural label characteristics. For the first time, this paper compares two popular learning frameworks, namely hierarchical support vector machine (SVM) and k nearest neighbor (k-NN) that are applied to a LSHTC task. Experiment results show that the latter outperforms the former in this LSHTC task, which is quite different from the usual results for normal text categorization tasks. Then this paper does a comparative study on different similarity measures and ranking approaches in k-NN framework for LSHTC task. Conclusions can be drawn that k-NN is more appropriate for the LSHTC task than hierarchical SVM and for a specific LSHTC task. BM25 outperforms other similarity measures and List Weak gains a better performance than other ranking approaches. We also find an interesting phenomenon that using all the labels of the retrieved neighbors can remarkably improve classification performance over only using the first label of the retrieved neighbors. © 2010 IEEE.

A Study on Recommendation Features for an RSS Reader

A Study on Recommendation Features for an RSS Reader

International Conference on Cyber-Enabled Distributed computing and Knowledge Discovery, CyberC

作者： Cansheng Ji Jingyu Zhou School of Software MOE-MS Key Laboratory for Intelligent Computing and Intelligent Systems Shanghai Jiaotong University Shanghai China

In the era of web 2.0, everyone can create and update content, and everyone can host a personal web site with little effort, making it hard to gather valuable information from different web sites. With RSS, people can read information from different resources in a uniform way, and in a single tool, such as an RSS reader. However, most of the RSS readers only display items in chronological order, which doesn't work well when users are inundated with too many items in the feeds. We propose using recommendation to help people find items in an RSS reader. Specifically, we consider profiled based features (i.e., text similarity and favorite fraction), update frequency, as well as Post Rank values for RSS recommendation. Experimental results indicate that favorite fraction and update frequency perform better than text similarity. Additionally, we also study the effect of feature combination and find that the combination of similarity and favorite fraction performs the best.

This paper presents a bi-brachiate robot for the inspection tasks of the high voltage power transmission line (HVPTL). The robot adopts a turning around method to get across the component (obstacles for the robot) installed on the HVPTL, and the process of the obstacle negotiation is expressed in detail. A simplified two-link model of the robot during obstacle negotiating stage is given. The adaptive fuzzy system is employed to approximate the model's uncertain nonlinear functions, and the robot controller is given based on the approximation result. Simulation and field experiment results illustrate the validity of the proposed controller and effectiveness of the inspection robot.
