We address the problem of processing continuous historical queries over streams of XML data, returning continuous, exact answers. The stream data considered are tokenized XML data with embedded updates for inserting, removing, or replacing stream subsequences that correspond to complete XML tree nodes when they are fully materialized to trees. Our query language for expressing historical querie...

introduction spect projections are contaminated by scatter radiation, resulting in reduced image contrast and quantitative errors. backscatter constitutes a major part of the scatter contamination in lower energy windows. the current study is an evaluation of the effect of backscatter material on fwhm and image quality investigated by monte carlo simulation. materials and methods simind program...

Thermal energy storage and solar radiation management are crucial to improve the sustainability efficiency of buildings. Compared with implementation phase change materials (PCMs) in opaque components, saving potential incorporating PCMs transparent glazing windows is much less studied not well understood. Here we present a comprehensive parametric study novel PCM for building focus on optimizi...

This paper presents the design of a Windows brain mapping application named brainmap Brain mapping is a technique that presents the spatial distribution of the electrical brain activ ity which is generated at the cortex and subsequently recorded on the scalp The brain map is constructed by interpolation of the measured scalp potentials at the electrode locations brainmap combines the e orts of ...

We consider time-space tradeoffs for exactly computing frequency moments and order statistics over sliding windows [16]. Given an input of length 2n− 1, the task is to output the function of each window of length n, giving n outputs in total. Computations over sliding windows are related to direct sum problems except that inputs to instances almost completely overlap. • We show an average case ...

Image segmentation is a major research area due to its extensive usage and application in the area of computer vision. It is the basis of Image analysis and understanding. Satellite Image segmentation is a challenging and tough task due to the inherent nature of the image. A wide variety of various segmentation techniques for colour satellite images have been developed. Here, we come up with an...

chemical composition and metabolizable energy of three camel browsed halophyte species (atriplex leucoclada, suaeda fruticosa, seidlitzia rosmarinus) were assessed and in vitro digestibility of dm (ivdmd), om (ivomd), ndf (ivndfd), adf (ivadfd) were determined using a completely randomized design. plant samples were collected based on camel's grazing patterns during the autumn-winter grazi...
