A unified method for statistical anomaly detection in intrusion detection systems is theoretically introduced. It is based on estimating a dispersion measure of numerical or symbolic data on successive moving windows in time and finding the times when a relative change of the dispersion measure is significant. Appropriate dispersion measures, relative differences, moving windows, as well as tec...

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...

Despite their potential to reduce energy consumption in buildings and increase user's comfort, the general application of smart windows is currently hampered by economic technological factors. To overcome these limitations, herein we report a new strategy for fabrication thermoresponsive based on polymer films loaded with paraffin nanoparticles. Proper selection components allows refractive ind...
