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...

Past research has firmly established the importance of knowledge sharing in R&D settings. However, current theories provide limited, biased, unsystematic and conflicting perspectives on the origination of knowledge sharing and are thus of limited guidance for knowledge management practices in R&D. To integrate and extend these fragmented insights we undertook two exploratory field studies of kn...

In the past, algebra has been predominantly used to define computer systems. However, computer systems are becoming more dynamic nowadays and algebra is not suitable anymore to define such systems. For this reason, coalgebra and coinduction have been introduced into the computer and information society. Coalgebra and coinduction present a powerful mechanism for representing many different kinds...

A chief problem in phylogenetics and database theory is the computation of a maximum consistent tree from a set of rooted or unrooted trees. A standard input are triplets, rooted binary trees on three leaves, or quartets, unrooted binary trees on four leaves. We give exact algorithms constructing rooted and unrooted maximum consistent supertrees in time O(2nm log m) for a set of m triplets (qua...

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...

This paper describes an improved model for multiple building diffraction modeling based on the uniform theory of diffraction (UTD). A well-known problem in conventional uniform theory of diffraction (CUTD) is multiple-edge transition zone diffraction. Here, higher order diffracted fields are used in order to improve the result; hence, we use higher order diffraction coefficients to improve a hy...
