In this paper we investigate relations between several masking schemes. We show that the Ishai–Sahai–Wagner private circuits construction is closely related to Threshold Implementations and the Trichina gate. The implications of this observation are manifold. We point out a higher-order weakness in higher-order Threshold Implementations, suggest a mitigation and provide new sharings that use a ...
Low Complexity Non Maximally Coefficient Symmetry Multi Rate Filter Bank for Wideband Channelization
For extracting the individual channels from input signal of wideband, Software Radio Channelizer was often used on multi-standard wireless communication. Despite effective channelizer design that decreases complexity computational, delay and power consumption is challenging. Thus, to promote effectiveness channelizer, we have provided Non-Maximally Coefficient Symmetry Multirate Filter Bank. th...
the present work concerns on the investigation of the role of polyethylene glycols (pegs) as masking agent for amelioration of extraction-separation of la(iii), eu(iii) and er(iii) ions by the acidic extractant bis(2-ethylhexyl)phosphoric acid (dehpa). the studied solvent extraction system is based on the combination of chelating effect of dehpa in the organic phase on the one hand, and the bin...
The paper describes an original method to represent chromi nance in color images and video This method can be combined with an arbitrary technique of luminance representation or compression The two chrominance components are represented by one scalar signal obtained using vector quantization The luminance is encoded entirely indepen dently from chrominance The scalar representation of chrominan...
Perceptual transparency requires local same-polarity X-junctions, which can also be generated by temporal integration under natural dynamic conditions. In this study, segmentation performance and target appearance were measured for a uniform gray target embedded in a random-dot frame presented with a temporally adjacent mask. Although static cues for both segmentation and transparency were unav...
Recent NICMOS observations of the central regions of nearby barred galaxies, NGC5383, NGC1530 and NGC1667 by Regan, Sheth and Mulchaey (1999), all show, in the unsharp mask map, a pair of distinct trailing spirals which can be followed all the way to the center. This result is in apparent conflict with the density wave theory. In this report, we argue that this difficulty may be removed if we t...
Previous research has revealed that dyslexic children may be more sensitive to backward-masking effects in auditory perception than control children. In this study, we asked whether a CV transition masks a preceding VC transition to a greater extent in dyslexic children than in controls. The results suggest that dyslexic children are severely impaired on the discrimination of VC sequences, rega...
Image bias is a usual phenomenon in MR imaging when using surface coils. It complicates the interpretation as well as the algorithmic postprocessing of such data. We introduce a bias correction algorithm based on homomorphic unsharp masking (HUM) that is applicable on a broad range of image types (as long as foreand background is separable), simple, fast and requires only minimal user interacti...
The DØ (DZERO) Detector at Fermilab has been collecting data since March 1, 2001. The detector has undergone an extensive upgrade to participate in the Run 2 data taking. The design of the detector meets the requirements of the high lumi-nosity environment provided by the accelerator. This paper describes the upgraded detector subsystems and gives an outline of the physics potentials associated...
