Abstract We consider a scenario where server is wirelessly connected to countless sensor nodes that continuously measure data. The task of the monitor sensors’ More precisely, at each time step calculates function defined over current measurements sensors. Since sensors only have small computational power and tight battery constraints, communication between should be as possible, i.e., we aim m...

Classification of streams and stream habitats is useful for research involving establishment of monitoring stations, determination of local impacts of land-use practices, generalization from site-specific data, and assessment of basin-wide, cumulative impacts of human activities on streams and their biota. This article presents a framework for a hierarchical classification system, entailing an ...

Multiple independent streams of random numbers are often required in simulation studies, for instance, to facilitate synchronization for variance-reduction purposes, and for making independent replications. A portable set of software utilities is described for uniform randomnumber generation. It provides for multiple generators (streams) running simultaneously, and each generator (stream) has i...

This document defines a new Session Description Protocol (SDP) media-level attribute: "label". The "label" attribute carries a pointer to a media stream in the context of an arbitrary network application that uses SDP. The sender of the SDP document can attach the "label" attribute to a particular media stream or streams. The application can then use the provided pointer to refer to each partic...

This paper extends for the first time semantic interpretation tools to infinite data in order to ensure Input/Output upper bounds on first order Haskell like programs on streams. By I/O upper bounds, we mean temporal relations between the number of reads performed on the input stream elements and the number of output elements produced. We study several I/O upper bounds properties that are of bo...

Streams of data often originate from many distributed sources. A distributed stream processing system publishes such streams of data and enables queries over the streams. This allows users to retrieve and relate data from the distributed streams without needing to know where they are located. Stream data is important not only for its current values but also for past values produced. In order to...

Michael Liebe argues that Salen and Zimmerman's interpretation of Huizinga's magic circle does not apply to computer games. Liebe's insight reveals not only a different relation for computer games to the magic circle, but also hints at a difference in the nature of rules in computer games. Jesper Juul's comparison of non-digital sports to simulations of those sports highlights a missing aspect ...
