The Heights of the Public School Pupils of San Marcos, Texas, Compared with those of the Burgess National Scale
… is the purpose of this study to compare the age-height distribution of San Marcos children to an accepted study of the age-height distribution for the children of the nation. To make such a comparative study between these heights and the heights for the child population of the United States it …

Stature and Criminal Behavior
… behavior and stature among American males. The heights, weights, stature scores (a function of the product of height and weight) and the body mass indices of criminals are examined as a whole, as well as by subgroup based on race, locality, and nature of the crime committed. The average weight …

The distributions of stellar remnants in disk galaxies
This thesis presents an account of work on the distribution of supernova remnants in galaxies. It consists of 3 parts, the identification of runaway stars in galaxies and then the modelling of the expected distribution of these stars around a galaxy and their expected dispersion over time. The …

Long wavelength X-ray microanalysis
… microanalyser. � Several methods of pulse height distribution analysis (deconvolution) are described practically a'tld analysed theoretically. One of the methods, in which the outputs from several pulse anal.yser channels are treated as a set of linear equations which can be solved …

An investigation of various computational techniques in optical fringe analysis.
… for three dimensional non-contact measurement of height distributions. A fringe pattern is projected onto an object's surface and, when viewed off-axis, it deforms to follow the shape of the object. The deformed fringe pattern is analysed to obtain its phase, information that is directly related …

A Coverage Area Estimation Model for Interference-Limited Non-Line-of-Sight Point-to-Multipoint Fixed Broadband Wireless Communication Systems
… within the 3.5 GHz multichannel multipoint distribution service (MMDS) band. The model is site-specific in that it uses statistical building/roof height distribution parameters obtained from practically modeling several metropolitan cities in the U.S. using geographic information system …

Three essays in environmental health
… term health indicators like birth weight and height-for-age, and others like weight-for-age, and child size at birth. This finding persists across various specifications, alternative control groups, and other robustness checks. I also examine the variation of this effect across birth …

Evaluation of amoxicillin, metronidazole and gentamicin dosage regimens for use in antibiotic prophylaxis in colorectal surgery
… by a onecompartment model. Elimination and distribution of amoxicillin and metronidazolewere affected by body weight. Elimination of gentamicin was influenced bycreatinine clearance and height. Distribution was affected by height.The findings of this study support 1000 mg of amoxicillin …

Using Airborne Laser Altimetry to Characterize Surface Fuels in Western Montana
… Metrics derived from LiDAR include canopy base height, canopy bulk density, biomass, crown height, basal area, and tree stem location. This study focuses on the surface fuel bed, defined as the two meter stratum above ground. The relationships between LiDAR-derived surface roughness and fuels …

Modelling the behaviour of a stationary horizontal liquid jet impinging on a vertical wall
… give detailed information about surface velocity distributions. Existing models for the impingement region gave reasonable predictions of the flow pattern. However, marked disagreement was found between the velocity field derived from these models and the velocities measured by PIV. The Nusselt …

Lightning/percipitation relationships on a global basis
… indicative of different regimes. Reflectivity-height distribution plots established reflectivity thresholds at 7 km and l O km where lightning over land completely dominates lightning over ocean. For reflectivity greater than 25 dBZ at 7 km altitude over land, there is 87% probability it will …

Stand dynamics, growth, and yield of genetically enhanced loblolly pine (Pinus taeda L.)
… changes in loblolly pine stand dynamics. Height-age relationships, height and diameter relationships and distributions, and intraspecific competition were investigated in second generation open-pollinated, controlled-pollinated, and clonal loblolly pine with an objective of characterizing …

Wave-induced liquefaction processes in marine sediments
… investigate the effect of randomness of wave height on seabed liquefaction, ensemble modelling approach is adopted in a two-layer inviscid fluid flow model, whereby the liquefied soil is treated as inviscid heavy fluid. Probabilistic study of soil liquefaction processes indicates that the …

Unveiling the History and Nature of the Milky Way with Galactic Surveys and Numerical Simulations
… the disc density profile, fitting the scale heights and lengths of mono-age, mono-[Fe/H] sub-populations in the high and low [α/Fe] disc. The fitted disc vertical scale height distribution is smooth when weighted by surface-mass density, suggesting that the high and low [α/Fe] populations are …

Early Undernutrition and Unmet Learning Needs: Exploring Relationships between Stunting, Cognition, and Teacher Perceptions of Early Grade Learning in Ghana
… birth record data were collected to calculate height-for-age z-scores, and household surveys collected data from caretakers to understand the extent to which additional equity dimensions including gender, rural location, and relative poverty affect cognition and classroom learning. Multivariate …

A High-Resolution Time-of-Flight Spectrometer for Fission Fragments and Ion Beams
… have been also investigated. From the MCP pulse-height-distribution spectra, a number for the forward-emitted SEs ejected by 35Cl beam was deduced. A method for obtaining widths of the SE energy distributions from the drop of the efficiency curve for various ions has been proposed. Assuming that …
