Drawing on neuroscience, we have developed a parallel, event-driven kernel for neurosynaptic computation, that is efficient with respect to computation, memory, and communication. Building on the previously demonstrated highly-optimized software expression of the kernel, here, we demonstrate TrueNorth, a co-designed silicon expression of the kernel.(More)
Publish-subscribe systems present the state of the art in information dissemination to multiple users. Such systems have evolved from simple topic-based to the current XML-enabled systems. Here, users pose complex queries (expressed in XPath) on the structure and content of the streaming documents. The parts of the documents that match the user queries are(More)
— In recent years, XML-based Publish-Subscribe Systems have become popular due to the increased demand of timely event-notification. Users (or subscribers) pose complex profiles on the structure and content of the published messages. If a profile matches the message, the message is forwarded to the interested subscriber. As the amount of published content(More)
Publish-subscribe (pub-sub) systems present the state of the art in information dissemination to multiple users.Current XML-based pub-sub systems provide users with considerable flexibility allowing the formulation of complex queries on the content as well as the structure of the streaming messages. Messages that contain one or more matches for a given user(More)
Current state of the art in information dissemination comprises of publishers broadcasting XML-coded documents, in turn selectively forwarded to interested subscribers. The deployment of XML at the heart of this setup greatly increases the expressive power of the profiles listed by subscribers, using the XPath language. On the other hand, with great(More)
The wide and increasing availability of collected data in the form of trajecto-ries has led to research advances in behavioral aspects of the monitored subjects (e.g., wild animals, people, and vehicles). Using trajectory data harvested by devices, such as GPS, RFID and mobile devices, complex pattern queries can be posed to select trajectories based on(More)

—Integer compression techniques can generally be classified as bit-wise and byte-wise approaches. Though at the cost of a larger processing time, bit-wise techniques typically result in a better compression ratio. The Golomb-Rice (GR) method is a bit-wise lossless technique applied to the compression of images, audio files and lists of inverted indices.(More)
