To see the effects of the direct X-ray in a Lanex screen-coupled CMOS APS imager, we measured modulation transfer function (MTF), noise power spectrum (NPS), and detective quantum efficiency (DQE). These measurements were performed under the condition of non-destructive test (NDT). By increasing the cumulative exposure on the imager, the MTF was degraded, and also leading to the DQE degradation...

We consider the list access problem and show that one questionable assumption in the original cost model presented by Sleator and Tarjan 13] and subsequent literature allowed for several competitiveness results of the move-to-front rule (MTF). We present an oo-line algorithm for the list access problem and prove that, under a more realistic cost model, no on-line algorithm can be c-competitive ...

On the basis of both Geschwind andBehan's (1984) theory—that at least part of the genesis of left-handedness can be ascribed to overexposure to testosterone during fetal development—andDorner's (1980;Dorneretal., 1991) theory—that transsexuality emerges from prenatal overor underexposure to androgens infemale-to-male (FTM) andmale-to-female (MTF) transsexuals, respectively—it was predicted that...

The modulation-transfer function (MTF) is a fundamental optical metric to measure the quality of an imaging system. In automotive industry it used qualify camera systems for ADAS/AD. Each modern ADAS/AD system includes evaluation algorithms environment perception and decision making that are based on AI/ML methods neural networks. performance these AI measured by established metrics like Averag...

Published experimental measurements of the ocular modulation transfer function (MTF) in the peripheral field are approximated by the expression T(f) = exp[-(f/fc)n], where T(f), f, fc, and n are modulation transfer, spatial frequency, spatial frequency constant and MTF index, respectively. It is shown that n (which describes the shape of the MTF) remains relatively constant at about 0.9 for fie...
