    A Novel High-Speed Architecture for Integrating Multiple DDoS Countermeasure Mechanisms Using Reconfigurable Hardware

    Get PDF
    In this paper, we proposed a novel high-speed architecture to incorporate multiple stand-alone DDoS countering mechanisms. The architecture separates DDoS filtering mechanisms, which are algorithms, out of packet decoder, which is the basement. The architecture not only helps developers to give more concentration on optimizing algorithms but also integrate multiple algorithms to achieve more efficient DDoS defense mechanism. The architecture is implemented on reconfigurable hardware, which helps algorithms to be flexibly changed or updated. We implemented and experimented the system using NetFPGA 10G board with incorporation of Port Ingress/Egress Filtering and Hop-Count Filtering to classify IP spoofing packets. The synthesis results show that the system runs at 118.907 MHz, utilizes 38.99% Registers, and 44.75% BlockRAMs/FIFOs of the NetFPGA 10G board. The system achieves the detection rate of 100% with false negative rate at 0%, and false positive rate closed to 0.16%. The experimental results prove that the system achieves packet decoding throughput at 9.869 Gbps in half-duplex mode and 19.738 Gbps in full-duplex mode

    Inductive and Transductive Few-Shot Video Classification via Appearance and Temporal Alignments

    Full text link
    We present a novel method for few-shot video classification, which performs appearance and temporal alignments. In particular, given a pair of query and support videos, we conduct appearance alignment via frame-level feature matching to achieve the appearance similarity score between the videos, while utilizing temporal order-preserving priors for obtaining the temporal similarity score between the videos. Moreover, we introduce a few-shot video classification framework that leverages the above appearance and temporal similarity scores across multiple steps, namely prototype-based training and testing as well as inductive and transductive prototype refinement. To the best of our knowledge, our work is the first to explore transductive few-shot video classification. Extensive experiments on both Kinetics and Something-Something V2 datasets show that both appearance and temporal alignments are crucial for datasets with temporal order sensitivity such as Something-Something V2. Our approach achieves similar or better results than previous methods on both datasets. Our code is available at https://github.com/VinAIResearch/fsvc-ata.Comment: Accepted to ECCV 202

    Complementary and Alternative Medicine Use among Physicians in Oriental Medicine Hospitals in Vietnam: A Hospital-Based Survey

    Get PDF
    Interest in complementary and alternative medicine (CAM) is growing worldwide, even in Vietnam where traditional medicine is considered mainstream. We conducted a survey of the knowledge, attitudes, and practices of CAM therapies among physicians in oriental medicine (OM) hospitals in Vietnam. A two-stage random selection process selected 337 physicians who were interviewed using a face-to-face method with a standardized structured questionnaire. Data from 312 physicians who completed the questionnaire suggested that oriental herbal medicine and acupuncture (Vietnamese OM version) were the more commonly used CAM modalities compared with Vietnamese folk medicine and other forms of CAM. A broad range of CAM modalities, particularly chiropractice, diet supplements, and dietary therapy, and an excessive proportion of western medication were employed in conjunction with OM in the physicians’ daily practice. Their daily practice was influenced by the source of knowledge, education level, medical specialty, and working environment. These findings suggest that physicians in OM hospitals in Vietnam have interests in various forms of CAM therapies besides traditional modes

    Status Poles and Status Zoning to Model Residential Land Prices: Status-Quality Trade off Theory (Short Paper)

    Get PDF
    This study describes an approach for augmenting urban residential preference and hedonic house price models by incorporating Status-Quality Trade Off theory (SQTO). SQTO seeks explain the dynamic of urban structure using a multipolar, in which the location and strength of poles is driven by notions of residential status and dwelling quality. This paper presents in outline an approach for identifying status poles and for quantifying their effect on land and residential property prices. The results show how the incorporation of SQTO results in an enhanced understanding of variations in land / property process with increased spatial nuance. A number of future research areas are identified related to the status pole weights and the development of status pole index
