In resource-constrained devices, adaptation of data stream processing to variations of data rates and availability of resources is crucial for consistency and continuity of running applications. However, to enhance and maximize the benefits of adaptation, there is a need to go beyond mere computational and device capabilities to encompass the full spectrum of contextawareness. This paper presen...

A neural model is described which uses oscillatory correlation to segregate speech from interfering sound sources. The core of the model is a two-layer neural oscillator network. The first layer of the network identifies connected regions of energy in the time-frequency plane (segments). In the second layer, segments that have a common fundamental frequency are grouped into streams. A stream is...

In 1993, the Georgia Diagnostic and Classification Prison (located near Jackson, GA) initiated an on-site composting operation to convert food waste into a useable by-product. Each week, inmates compost about 20 tons of food waste, which are mixed with ground cardboard, hay, yard leaves, or wood products. The operation takes place on a 1.2-ha site (3 acres) that drains towards a small, paermial...

in this paper a new process is presented for improving efficiency of cyclone de-dusting systems. the cyclone is coupled with a specially designed cylindrical chamber which includes a rotating tube inside it with air impinging nuzzles, drilled on the peripheral surface of the tube. the nuzzles help in pushing and throwing the particles to the outer radius distances during downward flow of dust i...

the objective of this study was to diagnose integrative ecological health of an urban stream,which is located in the asian temperate region. the research approach was primarily based on the index ofbiological integrity (ibi) using fish assemblage and a qualitative habitat evaluation index (qhei). and these indexes were compared with long-term conventional chemical dataset during 1996-2005. for ...

The numerical solution of a model describing a two-dimensional fluidized bed by a Chebyshev super spectral viscosity (SSV) method is considered. The model is in the form of a hyperbolic system of conservation laws with a source term, coupled with an elliptic equation for determining a stream function. The coupled elliptic equation is solved by a finite difference method. The mixed SSV/finite di...

This paper reviews applications of fuzzy logic to ECMA-368 based WiMedia UWB networks and proposes a fuzzy logic control scheme for dynamic channel allocation with combined prioritized contention access (PCA) and distributed reservation protocol (DRP). Such WiMedia UWB network is applicable to a wireless ship area pico-network for supporting both high-quality multimedia services on shipboard an...

Entropy is a central concept in both classical and quantum information theory, measuring the uncertainty and the information content in the state of a physical system. This paper reviews classical information theory and then proceeds to generalizations into quantum information theory. Both Shannon and Von Neumann entropy are discussed, making the connection to compressibility of a message strea...

The production of singleand mixed-sugar streams and their conversion to bioproducts were studied using sulfite pulping streams as feedstocks. Sulfite pulp, sludge, and spent sulfite liquor (SSL) were utilized because they are concurrently generated alongside of bleached pulp, and because the pulping process renders pretreatment unnecessary. SSL, comprised of mostly monomeric hexose and pentose ...

We investigate a range of crosslingual web retrieval tasks using the test suite of the CLEF 2005 WebCLEF track, which features a stream of known-item topics in various languages. Our main findings are: (i) straightforward indexing and retrieval is effective for mixed monolingual web retrieval; (ii) standard machine translation methods are effective for bilingual web retrieval; but (iii) standar...
