 Abstract:
 ... An experimental study aiming to estimate the firing distance was conducted using a 7.65mm×17mm Browning (.32ACP) pistol. Briefly, test shots were made against a target of cotton tissue (35cm×35cm), and the amounts of antimony (Sb), barium (Ba), and lead (Pb) deposited in quadrangular pieces (1cm×1cm) of the target cut from four radial positions at increasing distances from the bullet entrance hole ...

 Abstract:
 ... The C function which appears in the formulation for the bulk atmospheric boundary layer similarity (BAS) approach estimating sensible heat flux (H) at the surface under unstable stability conditions was examined to investigate its universality and whether or not it is a function of atmospheric stability alone, using data sets obtained from five largescale experiments that took place in diverse ge ...

 Abstract:
 ... The process of conducting a faecal egg count reduction test was simulated to examine whether arithmetic or geometric means offer the best estimate of efficacy in a situation where the true efficacy is known. Two components of sample variation were simulated: selecting hosts from the general population which was modelled by the negative binomial distribution (NBD), and taking an aliquot of faeces f ...

 Abstract:
 ... Various measures have been used to estimate height when assessing nutritional status. Current equations to obtain demispan equivalent height (DEHBassey) are based on a small sample from a single study. The objectives of this study were to develop more robust DEH equations from a large number of men (n = 591) and women (n = 830) aged 2545 y from a nationally representative crosssectional sample ...

A method for estimating flash flood peak discharge, hydrograph, and volume in poorly gauged basins, where the hydrological characteristics of the flood are partially known, due to stage gauge failure, is presented. An empirical index is used to generate missing hourly rainfall data and hydrologic and hydraulic models performs the basin delineation, flood simulation, and flood inundation. The peak ...

The FAO56 PM equation requires the numerous weather data that are not available in the most of the stations. The main goal of this paper is to present the software for estimating reference evapotranspiration, focusing on the feature of using ...

 Abstract:

With the recognition that eddy flux measurements are relatively accurate for a variety of common situations, a number of issues leading to inaccurate flux estimates and/or ambiguous interpretation of flux values are surveyed. These issues include inadvertent conversion of random errors to systematic errors, ambiguous differentiation between turbulence and other motions, and omission of transport b ...

 Abstract:
 ... Quantification of uncertainty of hydrological models has attracted much attention in hydrologic research in recent years. Many methods for quantification of uncertainty have been reported in the literature, of which GLUE and formal Bayesian method are the two most popular methods. There have been many discussions in the literature concerning differences between these two methods in theory (mathema ...

 Abstract:
 ... This study presents a hybrid spectral method (HSM) to estimate flow uncertainty in largescale highly nonstationary groundwater systems. Taking advantages of spectral theories in solving unmodeled smallscale variability in hydraulic conductivity, the proposed HSM integrates analytical and numerical spectral solutions in the calculation procedures to estimate flow uncertainty. More specifically, t ...

The average value for the weight coefficient (K(w)) was 0.57, whereas that for volume (K(v)) was 0.51. Accuracy of results obtained with these values was +/2.1% and +/3.5%, respectively. 3. The fresh weight and volume of Greater Rhea eggs can be easily estimated by mean ...

We used a well evaluated temperaturebased distributed energy balance model for snow accumulation and ablation with a 1 km x 1 km resolution to derive estimates of snow water equivalent (SWE) and snow cover area (SCA) for the American River basin during the water years 19601999. These model prognostic variables were then used to derive and analyze the properties of the snow depletion curves (SDC) ...

 Abstract:
 ... The aim of the paper is to demonstrate the incoherence, in terms of Bayesian inference, of the generalized likelihood uncertainty estimation (GLUE) approach, introduced by Beven and Binley in 1992. This results into a reduced capacity of the technique to extract information, in other words to "learn", from observations. The paper also discusses the implications of this reduced learning capacity fo ...

Progress has been made in the recent decade toward the mathematical relations describing the position of the sharp interface using hydraulic heads or pressures in coastal zones. This paper reviews several methods for estimation of the locati ...
