The sequence kernel has been shown to be a promising kernel function for learning from sequential data such as speech and DNA. However, it is not scalable to massive datasets due to its high computational cost. In this paper, we propose a method of approximating the sequence kernel that is shown to be computationally very efficient. More specifically, we formulate the problem of approximating the sequence kernel as the problem of obtaining a pre-image in a reproducing kernel Hilbert space. The effectiveness of the proposed approximation is demonstrated in text-independent speaker identification experiments with 10 male speakers--our approach provides significant reduction in computation time with limited performance degradation. Based on the proposed method, we develop a real-time kernel-based speaker identification system using Virtual Studio technology (VST).

Chigrin Nanonetworking Center in Catalunya N3Cat Universitat Politècnica de Catalunya Jordi Girona 1‐3 Campus Nord D6‐008 08034 Barcelona Spain Theoretical Nano‐Photonics Group Institute of High‐Frequency and Communication Technology Faculty of Electrical Information and Media Engineering University of Wuppertal Rainer‐Gruenter‐Str. 21 D‐42119 Wuppertal Germany Broadband Wireless Networking Laboratory School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta Georgia 30332 USA

Scattering of the terahertz radiation on a graphene‐based nano‐antenna is considered. Different electromagnetic models of graphene are discussed and applied to calculate extinction, scattering and absorption cross sections of the nano‐antenna. Scattering resonances in the terahertz band are identified as longitudinal Fabry‐Perot resonances of surface plasmon polaritons supported by the graphene layer. A simple while powerful model, based on the effective mode index of plasmon polaritons, is proposed to predict the antenna resonant properties. A systematic numerical study of the graphene‐based nano‐antenna is presented for different antenna dimensions. Finally, the potential of graphene‐based nano‐antennas for terahertz applications is discussed.

Time of day electric utility rates (TOU) are unavoidable. Consumers have no idea how TOU rates will impact their energy bills. Studies have shown that TOU accompanies by real-time feedback help reducing energy consumption and shifting loads to off-peak hours. Soon, smart meters with wireless communication capabilities will be in every household. Using the capabilities of smart meters, detailed usage of appliances can be provided to consumers via web applications. By allowing consumers to apply and test the impact of different rates, effectiveness of feedback based DSM can be enhances. Features and capabilities of web application are presented with a real world example.

作者： Bin Wu Pin-Han Ho Janos Tapolcai Peter Babarczi Department of Electrical and Computer Engineering University of Waterloo Waterloo ONT Canada Department of Telecommunications and Media Informatics Budapest University of Technology and Economics Budapest Hungary

We study SRLG (Shared Risk Link Group) failure monitoring and localization in all-optical WDM (Wavelength Division Multiplexing) networks. All links in each SRLG are logically grouped as a whole, and they fail at the same time when the SRLG failure event occurs. To achieve fast SRLG failure localization, monitoring is carried out at the optical layer using the recently proposed monitoring trail (m-trail) structure. By formulating an ILP (Integer Linear Program), we optimally solve the m-trail allocation problem to achieve unambiguous SRLG failure localization with the minimum monitoring cost. We claim that our work provides the first study in optimally allocating free-routed m-trails for achieving fast and unambiguous SRLG failure localization, with flexible tradeoff between the monitor cost and the bandwidth cost (i.e., supervisory wavelength-links).

UPnP single event mechanism for OPRoS robot S/W platform

UPnP single event mechanism for OPRoS robot S/W platform

In the future, robots will use various robot H/W platforms and their services will be composed of S/W components. Accordingly, it needs a robot S/W platform that provides standardized components and interfaces for fast robot development. OPRoS(Open Software Platform for Robotics Services) is a robot S/W platform that provides standardized components and interfaces. It uses the UPnP(Universal Plug and Play) as communication middleware. The UPnP is designed to bring easy-to-use, flexible, and standards-based connectivity to ad-hoc or unmanaged networks. We use UPnP eventing for push-style data transfer. But, the UPnP eventing has an inefficient factor for this. In this paper, we explain the reason and propose a single event mechanism to overcome the inefficiency.

The paper investigates failure localization in all-optical mesh networks using monitoring trails (m-trails) and monitoring trees (m-trees). By considering shared risk link groups (SRLGs) of different scenarios, integer linear programs (ILP) for m-trail/m-tree allocation are provided that can achieve unambiguous failure localization (UFL) of any single SRLG failure.

Google has recently released the video compression format VP8 to the open source community. This new compression format competes against the existing H.264 video standard developed by the ITU-T Video Coding Experts Group (VCEG) in collaboration with the ISO/IEC Moving Picture Experts Group (MPEG). This paper compares these two video coding standards in terms of video bit rate-distortion (quality) performance and the video network traffic variability with different long video sequences. We find that VP8 presently does not fulfill its promise to achieve twice the quality at half the bandwidth compared to H.264. The rate-distortion (RD) performance of VP8 is rather slightly below the RD performance of H.264. On the positive side, in contrast to H.264, VP8 has no license fees.

Modern machine learning techniques have encouraged interest in the development of vehicle health monitoring systems that ensure secure and reliable operations of rail vehicles. In an earlier study, an energy-efficient data acquisition method was investigated to develop a monitoring system for railway applications using modern machine learning techniques, more specific classification algorithms. A suitable classifier was proposed for railway monitoring based on relative weighted performance metrics. To improve the performance of the existing approach, a rule-based learning method using statistical analysis has been proposed in this paper to select a unique classifier for the same application. This selected algorithm works more efficiently and improves the overall performance of the railway monitoring systems. This study has been conducted using six classifiers, namely REPTree, J48, Decision Stump, IBK, PART and OneR, with twenty-five datasets. The Waikato Environment for Knowledge Analysis (WEKA) learning tool has been used in this study to develop the prediction models. © 2010 IEEE.

Enabling effective automated composition compensation with paired net for reliable web services transaction

Journal of Information and Computational Science 2010年第14期7卷 3027-3034页

Due to the existing failure and cancellation of business logic of Web services composition, service compensation is one of the most important issues in the research of Service-Oriented Computing (SOC). After analyzing compensation requirements by a motivation example, a paired-net based composition compensation mechanism is proposed to automatically implement partial or full compensation of the committed activities, where CSCP-Nets can be accurately constructed and agile compensation-triggered approach can be implemented. To ensure the weaker notion of atomicity through performing compensation, the verification on the significant properties of the compensation paired net system, such as the reachability, completeness, liveness and deadlock-freeness, is discussed that the related methods satisfy composition compensation's obligations. Finally a usual application case is illustrated and shows the proposed mechanism is feasible. Copyright © 2010 Binary Information Press.

In this paper, a novel adaptive predictive control is presented for a class of multi-input-multi-output (MIMO) nonlinear systems in block-triangular form with uncertain couplings of states/delayed states as well as inputs among subsystems. For each subsystem of the MIMO system, future states prediction is developed and using the predicted future states, adaptive predictive control is designed under certainty equivalence principal to compensate the parametric uncertainties in the couplings. To eliminate the functional uncertainties in the couplings, a novel compensation mechanism is developed for each subsystem. Under the proposed adaptive controls, all the signals in the closed-loop MIMO systems are guaranteed to be globally bounded. In addition, all the output tracking errors are guaranteed to converge to zeros. The effectiveness of the proposed control is demonstrated in the simulation. © 2010 AACC.
