This study considers uncertainty about the number of surviving children. Under prohibition of child labor, a higher survival probability of a child can increase opportunities for education investment as the fertility rate declines with a temporary increase in the number of surviving children. However, per capita GDP may decrease until the start of education investment. When people accumulate th...

Given the values of a measurable function m : Rd → R at n arbitrarily chosen points in Rd the problem of estimating m on whole Rd, such that the L1 error (with integration with respect to a fixed but unknown probability measure) of the estimate is small, is considered. Under the assumption that m is (p, C)-smooth (i.e., roughly speaking, m is p-times continuously differentiable) it is shown tha...

Cost overrun of software projects is major cause of their failures. In order to facilitate accurate software cost estimation, there are several metrics, tools and datasets. In this paper, we evaluate and compare different metrics and datasets in terms of similarities and differences of involved software attributes. These metrics forecast project cost estimations based on different software attr...

We estimated the perceptual entropy rate of the phonemes of American English and found that the upper limit of the perceptual entropy of voiced phonemes is approximately 1.4 bit/sample, whereas the perceptual entropy of unvoiced phonemes is approximately 0.9 bit/sample. Results indicate that a simple voiced/unvoiced classi cation is suboptimal when trying to minimize bit rate. We used two di er...

SUMMARY This paper deals with a quite general nonparametric statistical curve estimation setting. Special cases include estimation of probability density functions, regression functions and hazard functions. The class of "fractional delta sequence estimators" is defined and treated here. This class includes the familiar kernel, orthogonal series and histogram methods. It is seen that, under som...

The slope length and steepness (LS) factor is one of the factors in the Revised Universal Soil Loss Equation (RUSLE) needed to estimate average annual erosion rate. The LS factor is often derived from digital elevation models (DEM). DEM errors and uncertainty could affect LS factor estimation and consequently erosion rate estimation. However, DEM uncertainties are not always accounted for, and ...

An IC for consumer 100 Hz television is presented 1 . It applies motion estimation and compensation techniques for very highquality field rate up-conversion and a judder-free motion portrayal of movie material.

Propagation of radio occultation (RO) signals through the lower troposphere results in high phase acceleration and low signal to noise ratio signal. The excess Doppler estimation accuracy in lower troposphere is very important in receiving RO signals which can be estimated by sliding window spectral analysis. To do this, various frequency estimation methods such as MUSIC and ESPRIT can be adopt...
