OBJECTIVE The aim was to evaluate the intra- and inter-examiner reliability of two methods, namely, digital caliper [DC] and computerized image analysis software (Image Tool [IT] version 4.1) for measuring the area of an active enamel demineralization lesion. The effect on that measurement of a window that delimits the lesion was also assessed. MATERIALS AND METHODS Thirty-eight circular arti...

Abstract We propose an extended one-shot decorrelating detector (EOS-DD) for asynchronous DS/CDMA systems in frequency selective fading environments. The EOS-DD extends a processing window to several symbol duration. The received signal over an extended window is utilized for the decorrelator in the EOS-DD. The effects of the window size on BER performance are investigated by numerical analysis...

SUMMARY A Perl utility called SCANMS was written that operates on parametric bootstrap data generated by Hudson's simulator MS. SCANMS simulates sliding window analysis of Tajima's D or Fu and Li's D(*) or F(*) over the replicates and generates the empirical joint distribution of window minima and maxima. This distribution may then be used to calculate achieved significance values or significan...

introduction: the different factors that affect the camera uniformity of single photon emission computed tomography (spect) technique have been analyzed including peak shift (%) and window width of energy. the effect of peak shift and window width on spect image uniformity has been investigated using a point source to perform intrinsic flood images. methods:the relation between calculated integ...

We carried out an elastic and plastic analysis successfully against a new type beryllium window for the SPring-8 front ends. The new window has beryllium foils of high-purity and fine-surfaceroughness on user’s demand. It was confirmed that the new foil has only about half the mechanical strength of the existing one by a static tensile test. Based on the analysis solutions and the tensile test ...

We present a multi–window method for obtaining the time-frequency spectrum of of nonstationary signals such as speech and music. This method is based on optimal combination of evolutionary spectra that are calculated by using multi–window Gabor expansion. The optimal weights are obtained by using a least square estimation method. An error criterion that is the squared distance between a referen...
