Data streams have emerged as an important research area in recent years due to its ubiquitous presence in various application domains including stock market analysis in finance. Therefore, it has become increasingly demanding to develop efficient techniques to discover useful patterns from such data streams. Among many issues, analyzing the correlation between two data streams is an important t...

Video streaming technique is widely used in the Internet with the development of access networks. Although some techniques such as Forward Error Correction or Content Distribution Network are effective for video streaming services, they are not sufficient in the case that streams are suffered from heavy packet loss. For this problem, we propose a novel error correction method called “ECLIPSE: E...

This work revisits the study of streaming algorithms where both input and output are data streams. While streaming algorithms with multiple streams have been studied before, such as in the context of sorting, most assumed very nonrestrictive models and thus had weak lower bounds. We consider data streams with restricted access, such as read-only and write-only streams, as opposed to read-write ...

Data streams are a prevalent and growing source of timely data. As streams become more prevalent, richer interrogation of the contents of the streams are required. Value of the content increases dramatically when streams are aggregated and distributed global behavior can be interrogated. In this paper, we demonstrate that access to multiple data streams should be viewed as one of deriving meani...

This paper presents a real-time auditory and visual tracking of multiple objects for humanoid under real-world environments. Real-time processing is crucial for sensorimotor tasks in tracking, and multiple-object tracking is crucial for real-world applications. Multiple sound source tracking needs perception of a mixture of sounds and cancellation of motor noises caused by body movements. Howev...

The ability to parse a complex auditory scene into perceptual objects is facilitated by a hierarchical auditory system. Successive stages in the hierarchy transform an auditory scene of multiple overlapping sources, from peripheral tonotopically based representations in the auditory nerve, into perceptually distinct auditory-object-based representations in the auditory cortex. Here, using magne...

Background Government policy measures have a key role to play in the prevention and control of noncommunicable diseases (NCDs). The Caribbean, a middle-income region, has the highest per capita burden of NCDs in the Americas. Our aim was to examine policy development and implementation between the years 2000 and 2013 on NCD prevention and control in Barbados, and to investigate factors promotin...

Extended Abstract The extension of database systems to support multimedia applications requires new mechanisms to ensure the synchronized presentation of multiple media data streams. In order to exibly and eeciently present multimedia data streams to users, media streams must be segmented into media objects and time constraints among these objects must be speciied and maintained. New management...

We propose a practical approach to the progressive processing of (FWR) XQuery queries on multiple XML streams, called Twig’n Join (or TnJ). The query is decomposed into a query plan combining several twig queries on the individual streams, followed by a multi-way join and a final twig query. The processing is itself accordingly decomposed into three pipelined stages progressively producing stre...
