This study compared the performance measures for a variety of newborns’ weight-for-height indicators based on machine learning, ultrasonographic data and maternal/delivery information. The source of data for this study was a multi-center retrospective study with 2949 mother–newborn pairs.

Assman top height is a parameter whose measurement or estimation is tiring in the practice and presents some inconveniences from a stadistical point of view which lessens efectiviness. Considering it’s a dasometric parameter widely used in Spain and with important silvicultural implications, we consider it suitable to look for alternatives which solve the faults of the aforesaid top height. In this paper we propose, as an alternative, the criterion used by the English management tables that not only consider with accuracy the top height concept but is more operative from a practical point of v

Background: For the past 50 years, standard guidelines have recommended the use of sex-adjusted mid-parental height to predict a child’s final height. Here, we studied the accuracy of this procedure. Methods: We used height data in a cohort of 23 very large nuclear families (mean = 11 adult children per family). We compared the actual final height of the children to their height predicted by the standard procedure, as well as to alternative height predictions that incorporate corrections of mid-parental height for age, sex, and regression to the mean.

Abstract. In order to obtain the observed scale height at high altitude a calculation method has been derived for determining density scale height from the difference between two satellite's heights. Two balloon satellites, Chinese DQ-1A and DQ-1B, were launched together into a nearly circular orbit at a height near 900 km and they were together in orbit for 190 days. According to the difference of the orbital heights of these two balloon satellites from 19 September 1990 to 9 March 1991, 67 values of density scale height at heights of about 544–877 km were determined.

Most of the plumes either spread near the tropopause at 16–17 km altitude or penetrated the stratosphere at 18–20 km altitude. Overshooting tops reached heights of up to 23 km. These geometric heights were compared with radiometric heights corresponding to the coldest plume temperature, which usually represent ambiguous estimates within a wide range between a tropospheric and a stratospheric height m

Estimates for prediction variances are obtained both for diameters and volumes. The approach is multivariate and nonparametric. At the estimation stage, a multivariate model is developed for the total height and a fixed set of diameters: four diameters at absolute heights below breast height and eight diameters at relative distances between the breast height and

Abstract A study conducted in 2000 determined effects of two rates of Cutless and B-Nine/Cycocel tank mix and initial plant height on vegetative growth and flowering of Canna x generalis ‘Florence Vaughan’. Canna lily responded independently to plant growth retardant (PGR) treatment and initial plant height. Cutless suppressed vegetative height consistently up to 34% at the lower rate (25 ppm) and up to 41% at the higher rate (50 ppm) throughout the study, regardless of initial plant height. At first and second flower, increasing rates of Cutless suppressed vegetative height about 36% and 35–4

Objective This study examined the effect of using a variable-height staple construct containing three rows of staples with heights of 3.0, 3.5, and 4.0 mm (staple leg length, medial to lateral) versus standard three-row single-height staplers (with staple heights of either 3.5 or 4.8 mm) for pneumostasis in healthy porcine and canine lung parenchyma to determine whether a single stapler that uses variable staple heights could perform as well as, or better than, existing single-height stapling devices. The work presented here used healthy animal tissues, in lieu of diseased tissue, which is ext

High-value timber species such as monarch birch (Betula maximowicziana Regel), castor aralia (Kalopanax septemlobus (Thunb.) Koidz), and Japanese oak (Quercus crispula Blume) play important ecological and economic roles in forest management in the cool temperate mixed forests in northern Japan. The accurate measurement of their tree height is necessary for both practical management and scientific reasons such as estimation of biomass and site index. In this study, we investigated the similarity of individual tree heights derived from conventional field survey, digital aerial photographs derive

National height reference coordinate systems are based on levelling networks classified into orders, according to their accuracy. Traditionally, height systems are realized by applying the parametric adjustment and the least squares method. Any kind of correlation between the observations as well as the correlation of fixed heights is often neglected for pragmatical reasons. Also, given heights are usually assumed error-free when in reality they possess a certain level of accuracy. This paper presents an alternative realisation of the height reference system HVRS71 for the Republic of Croatia.

Subsampling and subsequent imputation of tree heights can improve the predictive performance of stand volume estimation but may also introduce biases. Using coastal Douglas-fir data from southwest Oregon, USA, the predictive performance of several height imputation strategies for estimating stand volume was evaluated. A subsample of 1–15 trees was randomly selected per stand, and missing heights were imputed using a regional Chapman–Richards function with diameter only and diameter plus stand density measures, fitted using a nonlinear least-squares model (NFEM) and a nonlinear mixed-effects mo

This study examines the conversion strategy of 2D to 3D cadastral maps by standardizing the height limits of land rights based on LU/LC. To achieve 3D cadastral maps, the research proposes a conversion strategy considering height factors. The height dimension of cadastral maps faces challenges in determining maximum heights for features like buildings, given varying regional regulations. As a solution, the concept of surface feature height (SFH) is applied along with LU/LC classification. Economic considerations, such as state revenue from taxes, are also factored into the proposed height limi

The distribution of canopy heights obtained with an airborne laser scanner over a field trial with Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) was a function of the vertical distribution of foliage area. Over a wide range of canopy structures, the proportion of laser pulses returned from or above a given reference height was proportional to the fraction of leaf area above it. We hypothesized that the quantile of the laser canopy heights matching in probability the fraction of leaf area above a desired height would be an unbiased estimator of same. This was confirmed in 36 (20 × 20 m) pl

Abstract. We use the global circulation model ECHAM6 extended by the aerosol module HAM2 to simulate global patterns in wildfire emission heights. Prescribed plume heights in ECHAM6 are replaced by an implementation of a simple, semi-empirical plume height parametrization. In a first step, the global performance of the plume height parametrization is evaluated for plumes reported in the MISR Plume Height Project data set. Our results show that the parametrization simulates a largely reasonable global distribution of plume heights. While the modeled global mean plume height (1411±646 m) is in g
