We propose a novel method for simultaneous noise reduction and data compression based on shrinking, quantizing and coding the wavelet packet (WP) coeecients. A dynamic programming and fast pruning algorithm is used to eeciently choose the best basis from the entire library of admissible WP bases, and jointly optimize the bit allocation strategy and the quantization scheme in the rate-distortion...

The most common descriptor of afterload in the clinical setting is peripheral vascular resistance. Nonetheless, this is only one of the elements of afterload. A comprehensive descriptor of left ventricular extrinsic afterload is contained in the 3-element Windkessel (wind-chamber) model. Although this Windkessel circulatory model contains only characteristic impedance, aortic compliance and per...

In this paper, the theoretical perfectly absorbing boundary condition on the boundary of a half{space domain is developed for the Maxwell system by considering the system in whole instead of considering each component of the electromagnetic elds individually. This boundary condition allows any wave motion generated within the domain to pass through the boundary of the domain without generating ...

This interactive exhibition introduces a multimedia experience using an interactive kaleidoscope, called an Iamascope. The Iamascope uses a video camera lens as the eye of a kaleidoscope and projects a kaleidoscopic image of the performer onto a large screen. A vision subsystem is coupled to the electronic eye to control musical tones using a sustain algorithm. Finally, a wireless microphone is...

Quasi-simultaneous measurements of the ocean surface by the Canada Centre for Remote Sensing (CCRS) Convair-580 (CV-580) synthetic aperture radar (SAR) were acquired on March 20, 1988, along an ascending pass of the Geosat radar altimeter as part of the prelaunch ERS-1 Norwegian Continental Shelf Experiment (NORCSEX '88). Over a region where the SAR look direction is parallel to the wind vector...

Despite the progress in critical geographic information systems (GIS) research in recent years [1], geographical discourse is still dominated by dualist thinking that understands GIS largely as a tool for quantitative or empiricist spatial analysis. This dualist understanding of geographical methods—which was partly fuelled by the erce polemics between critical geographers and GIS users/researc...

Previous work investigating temporal integration in the formation of the auditory evoked ®eld component, M100, indicates an accumulation of stimulus attribute information in the processes underlying the M100 response with a temporal window for this integration of 25±32 ms. We investigate the in ̄uence of stimulus duration on M100 amplitude using sinusoidal tone stimuli of increasing duration und...

Experimental results show that specifi c binding between a ligand and surface immobilized receptor such as hybridization of single-stranded DNA (ssDNA) immobilized on a microcantilever surface leads to cantilever defl ection. The binding induced defl ection may be used as a method for detection of biomolecules, such as pathogens and biohazards. Mechanical deformation induced because of hybridiz...
