Determination of streamflow characteristics for ungaged Texas streams using regression analysis
The harmonic mean, 7Q2 (7-day, 2-year low-flow), and 7Q10 are streamflow characteristics used to determine stream waste load allocations. Predictive equations for these characteristics of ungaged Texas streams are developed using multiple regression analysis to relate streamflow characteristics to …

Seasonal Movements, Habitat Use Patterns and the Effects of Human Disturbances on Elk in Custer State Park, South Dakota
… Annual home ranges of these herds overlapped a mean of 18% (Range = 9-29%, SE = 3.2, n = 5) for cows and 27% (Range = 11-42%, SE = 5.8, n = 6) for bulls. Home range sizes of CSP elk varied with method of analysis, season, and sex. Mean 95% harmonic mean annual home range size was 6,090 ha for …

The Effects Of Diffusion, Capillary Heterogeneity, And Porous Media Morphology On CO2 Migration In Porous Media
… and increasing buoyancy forces. We also used a harmonic mean model to estimate the effective diffusivity in a Room Temperature Ionic Liquid (RTIL) membrane. A metallic porous membrane was thoroughly saturated with Emim(Tf2N) and placed in a diffusion chamber. CO2 gas was injected into the upper …

Home ranges and habitat selection of red-shouldered hawks in Central Maryland: evaluating telemetry triangulation errors
… were delineated using the convex polygon and harmonic mean models. Habitat occurrence was described from a digitized cover type map. Average home range sizes based on point estimates and simulated point estimates for 3 male hawks were larger than average home range areas for 2 female hawks. …

Estimation in Truncated Exponential Family of Distributions
… on 0,T , T > 0 known, whenever the sample mean x (GREATERTHEQ) T/2.</p> <p>(ii) Broeder 1955 shows that the maximum likelihood estimator of the scale parameter of a truncated gamma distribution, with the shape parameter being known, becomes infinite with positive probability whenever the …

Mathematical Analysis of Upscaling Well Log Data from Sonic to Seismic Resolution
… from the other, thus we explore the various mean calculations. The Pythagorean means (arithmetic, harmonic, and geometric) are three different way to average a set of numbers. Using a 2D layered earth model with homogenous and isotropic layers, the results of applying the Pythagorean means …

Winter movements and habitat use of northern saw-whet owls at Assateague Island, Maryland
… and shape. I also calculated adaptive kernel, harmonic mean, and minimum convex polygon home ranges for comparison of these methods. Habitat composition in 30% home ranges was compared with 95% home ranges and 30% and 95% home ranges were each compared with composition of the entire study area …

What Mean Do You Mean?
… this paper, I discuss the different types of means and how or when they would be applied. The four means include arithmetic, geometric, harmonic, and the root mean square. I go over real life examples and show the calculations of each. Along with the four means, I also found that the equation …

Analysis of word-order universals using Bayesian phylogenetic inference
… that the Bayes Factors computation using the harmonic mean estimator is very unstable, and that many of the results reported by Dunn et al. are irreproducible. We also found that the computation is very sensitive to the accuracy of the data because a one-digit error can alter the Bayes Factors …

Home range behavior of Roosevelt elk in Strathcona Park
… were determined for each study animal using the harmonic mean estimator of Program Home Range. Three seasonal models (summer, mild winter, and severe winter) of habitat suitability were tested using a non-migratory elk group. A Geographic Information System (GIS) was used to create a digital map …

Patterns and mechanisms of heat transport in the northern Denver Basin Nebraska, South Dakota and Wyoming
… samples from drill cuttings, yielding a harmonic mean thermal conductivity value of 1.52 ± 0.91W m-1 K-1 for the stratigraphic column of the study area. A total of 929 thermal gradient values compiled from several databases were incorporated with thermal conductivity data to produce a …

Using Siamese neural networks to identify individual animals
… observation is being conducted by photographic means creating the need to be able to identify individual animals from images [Weinstein, 2018]. The dissertation answers whether machine learning can determine if the animals in a pair of images come from the same individual animal. To answer this …
