This paper introduces the MSR-Bing grand challenge on image retrieval. The challenge is based on a dataset generated from click logs of a real image search engine. The challenge is to mine semantic knowledge from the dataset and predict the relevance score of any image-query pair. A brief introduction to the dataset, the challenge task, and the evaluation method will be presented. And then the methods...
Video sharing has been an increasingly popular application in online social networks (OSNs). However, its sustainable development is severely hindered by the intrinsic limit of the client/server architecture deployed in current OSN video systems, which is not only costly in terms of server bandwidth and storage but also not scalable. The peer-assisted Video-on-Demand (VOD) technique, in which participating...
DDoS attack is a major Internet security problem-DoS is that lots of clients simultaneously send service requests to certain server on the internet such that this server is too busy to provide normal services for others. Attackers using legitimate packets and often changing package information, so that traditional detection methods based on feature descriptions is difficult to detect it. This paper...
XML (Extensible Markup Language) describes the particular structural relationship between nodes, XML encoding scheme is to assign the unique number to each node, and realizes fast operation through the numbered structure reflecting the structure of nodes. With the expanding application fields of XML, the characteristics of each area should be reflected in the encoding process of XML. This paper analyzes...
It requires accurate synchronization among the MCU, servo controllers and sensors in CNC systems for time stamping of data and motion control. This paper presents the design and implementation of time synchronization for CNC systems which employ switched Ethernet as its communication module. The method adopts the clock of switches as the master clock instead of that of MCU which usual is. To obtain...
