A b s t r a c t . We examine the effects of changing the coefficient of variation (CV) of the inter-stimulus interval on the CV of the output interspike interval (ISI), using constant magnitude, supra-threshold pointprocess stimuli of the membrane potential variable in the FitzHughNagumo model. The coefficient of variation of the input is changed within the context of a displaced exponential di...

external fluted feed rolls are commonly used in grain drills. the fluted feed roll meters a volume of seeds and does not singulate the seeds as do the precision planters; therefore, there will be inherent variation in the number of seeds delivered per unit of time. this research was conducted to investigate the effect of seed meter drive shaft and ground speeds and outlet positions in a grain d...

investigation of inter-storm variability of runoff and soil loss characteristics helps experts and decision makes better understanding of hydrological response. however, this important has been less considered in the world, especially developing countries. the present study was therefore planned to evaluate the effect of different rainfall intensities and slopes on inter-storm variability of co...

This study aims to determine the amount of production risk, cost risk and income rice farmers in Polenga Village, Watubangga District, Kolaka Regency. The basic method used this research is quantitative descriptive. Determination sample using simple random sampling method, with a total 48 farmers. results are risks faced by Kecamtan Watubangga, which costs risk. Based on value variation coeffic...

Introduction. Performance of nonuniformity correction approaches is usually evaluated indirectly, on the basis of remaining tissue intensity variability rather than the actual estimated bias field. Common indirect measures include coefficient of variation of white matter CV(WM) and gray matter CV(GM), and coefficient of joint variation CJV between WM and GM [1]. However, disagreements between i...

Images (for example, photomicrographs) are routinely used as qualitative evidence of the microstructure of foods. In quantitative image analysis it is important to estimate the area (or volume) to be sampled, the field of view, and the resolution. The bootstrap method is proposed to estimate the size of the sampling area as a function of the coefficient of variation (CV(Bn)) and standard error ...
