Multiple trophic levels of a forest stream linked to terrestrial litter inputs

by J. B. Wallace, S. L. Eggert, J. L. Meyer, J. R. Webster - Science , 1997
"... The importance of terrestrial-aquatic linkages was evaluated by a large-scale, 3-year exclusion of terrestrial leaf litter inputs to a forest stream. Exclusion of leaf litter had a strong bottom-up effect that was propagated through detritivores to predators. Most invertebrate taxa in the predominan ..."

On Peer-to-Peer Media Streaming

by Dongyan Xu , Mohamed Hefeeda, Susanne Hambrusch, Bharat Bhargava
"... In this paper, we study a peer-to-peer media streaming system with the following characteristics: (1) its streaming capacity grows dynamically; (2) peers do not exhibit serverlike behavior; (3) peers are heterogeneous in their bandwidth contribution; and (4) each streaming session may involve multip ..."

Mining Data Streams: A Review.

by Mohamed Medhat Gaber , Arkady Zaslavsky , Shonali Krishnaswamy - SIGMOD Record, , 2005
"... Abstract The recent advances in hardware and software have enabled the capture of different measurements of data in a wide range of fields. These measurements are generated continuously and in a very high fluctuating data rates. Examples include sensor networks, web logs, and computer network traff ..."

of data stream mining applications. The paper is organized as follows. Section 2 presents the theoretical background of data stream analysis. Mining data stream techniques and systems are reviewed in sections 3 and 4 respectively. Open and addressed research issues in this growing field are discussed

Adding Multimedia to the Semantic Web -- Building an MPEG-7 Ontology

by Jane Hunter
"... For the past two years the Moving Pictures Expert Group (MPEG), a working group of ISO/IEC, have been developing MPEG-7 [1], the "Multimedia Content Description Interface", a standard for describing multimedia content. The goal of this standard is to develop a rich set of standardized too ..."

to describe audiovisual information regardless of storage, coding, display, transmission, medium, or technology. It will address a wide variety of media types including: still pictures, graphics, 3D models, audio, speech, video, and combinations of these (e.g., multimedia presentations). MPEG-7 is due

Riparian vegetated buffer strips in waterquality restoration and stream management

by Lewis L. Osborne, David A. Kovacic - Freshwater Biology , 1993
"... 1. A review is presented of the literature on riparian vegetated buffCT strips (VBS) for use in stream-water-quality restoration and limitations associated with their use are discussed. The results are also presented of recent investigations on the effectiveness of a forested and a grass vegetated b ..."

buffer strip for reducing shallow subsurface inputs of nutrients from agriculture to a stream in central Illinois, U.S.A. 2. Because riparian zones link the stream with its terrestrial catchment, they can modify, incorporate, dilute, or concentrate substances before they enter a lotic system. In small

An analysis of live streaming workloads on the Internet

by Kunwadee Sripanidkulchai, Bruce Maggs - in Proc. of ACM IMC , 2004
"... In this paper, we study the live streaming workload from a large content delivery network. Our data, collected over a 3 month period, contains over 70 million requests for 5,000 distinct URLs from clients in over 200 countries. To our knowledge, this is the most extensive data of live streaming on t ..."

A TRACE-BASED APPROACH FOR MODELING WIRELESS CHANNEL BEHAVIOR

by Giao T. Nguyen, Randy H. Katz, Brian Noble, Mahadev Satyanarayanan , 1996
"... The loss behavior of wireless networks has become the focus of many recent research efforts. Although it is generally agreed that wireless communications experience higher error rates than wireline, the nature of these lossy links is not fully understood. This paper describes an effort to characteri ..."

to characterize the loss behavior of the AT&T WaveLAN, a popular in-building wireless interface. Using a trace-based approach, packet loss information is recorded, analyzed, and validated. Our results indicate that WaveLAN experiences an average packet error rate of 2 to 3 percent. Further analysis reveals

MIMO Systems with Antenna Selection

by Andreas F. Molisch, Moe Z. Win , 2004
"... Multiple-input–multiple-output (MIMO) wireless systems are those that have multiple antenna elements at both the transmitter and receiver [1]. They were first investigated by computer simulations in the 1980s [2], and later papers explored them analytically [3], [4]. Since that time, interest in MIM ..."

Measurement of Commercial Peer-to-Peer Live Video Streaming

by Shahzad Ali, Anket Mathur, Hui Zhang , 2006
"... Peer-to-peer technologies have proved to be effective for various bandwidth intensive, large scale applications such as file-transfer. For many years, there has been tremendous interest in academic environments for live video streaming as another application of P2P. Recently, a number of new commerc ..."
