Petrography, chemical composition, and stratigraphic setting of the coals of North-Central Missouri
… sampled. The BTU content of the coals has an arithmetic mean of 10,447 as received. The arithmetic mean of the sulfur content of the coals is 4.69 percent as received of which 3.26 percent is pyritic, 1.39 percent is organic, and 0.04 percent is sulfate. The weighted average sulfur content …

A stand level multi-species growth model for Appalachian hardwoods
… trees per acre, minimum stand diameter, and arithmetic mean dbh) were projected through time for the whole stand and for individual species groups. Future diameter distributions were obtained using the three-parameter Weibull probability density function and parameter recovery method. 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 …

The gamma distribution as an alternative to the lognormal distribution in environmental applications
… model. The upper confidence limit (UCL) of the arithmetic mean of a lognormal population is computed by using the H-statistics. Recent concerns have arisen to the effectiveness of the H-Statistic based UCL for the mean of the lognormal distribution in instances of moderately to highly skewed …

Indoor atmospheric radon in Hamadan, Iran. Atmospheric radon indoors and around Hamadan city in Iran.
… type CR-39 exposed for three month periods. The arithmetic mean radon concentration in Hamadan buildings was determined to be 80 Bqm-3 and also an average indoor annual effective dose equivalent for the Hamadan city population was calculated as 1.5 mSv. Maximum radon concentrations were noted …

Optimization-based selection of influential agents in a rural Afghan social network
… agent assignment strategy producing the greatest arithmetic mean of the expected long-term attitude of the population. We demonstrate in experiments the merits of the optimization model in nonlethal targeting, which performs significantly better than both doctrine-based and random methods of …

Developing an interactive overview for non-visual exploration of tabular numerical information
… auditory perception and cognition to extract meaning from HDS representations could be used to reliably estimate relative arithmetic mean values within large tabular data sets. Following a user-centred design methodology, HDS was implemented as the primary form of overview information display …

Evaluation of Genetic Diversity and Stability of Colocasia Cultivars Using ISSR
… was examined. Unweighted pair group method with arithmetic mean (UPGMA) and principal coordinate analysis (PCO) were performed to examine genetic relationship that can explain a need for the new classification <em>Colocasia gigantea</em> and recent movement of re-classifying <em>Colocasia …

Generalized Probabilistic Bowling Distributions
… distribution of each frame’s scores and the arithmetic mean for frames on pins. Finally, to summarize the variety of distributions, we shall make tables that display the results obtained from each distribution used to model a particular bowler’s score. We evaluate the special case when …

Accurate Quantum Mechanical Decoupling Approximations for Molecular Scattering Theory
… with the partial wave parameter chosen to be the arithmetic mean of the initial and final l-quantum numbers, the corrected centrifugal decoupling approximation gives significantly more accurate inelastic differential and integral state-selected cross sections than its uncorrected counterpart.

Gaussian process regression approach to pricing multi-asset American options
… the performance of GPR-MC, an American geometric mean basket put option, an American arithmetic mean basket put option and an American maximum call option are priced under the multi-asset Black-Scholes and Heston models, using both GPRMC and LSM. The algorithms are run a 100 times to obtain mean …

An analysis of financial statements of Virginia's retail farm equipment businesses
… existed among sales groups. Separation of means was used to determine which means were significantly different. The standard deviation and coefficient of variation were calculated to measure the variation among firms. The range, arithmetic mean, and median were also computed. Regression …

Effective properties for flow in heterogeneous porous media
… of soil properties at local scale on the mean behavior of heterogeneous flows were investigated via Monte Carlo method. Assuming log-normal distribution of conductivity and capillary pressure head being a stochastic process, the mean behavior model defined by effective properties was …

Sampling spatial sediment variation in gravel-bed streams
… known accuracy level. It then suggests that the arithmetic mean is a suitable parameter to characterize the coarseness of individual sediment deposits within a sampled area. Thus, by recording the size and location of each stone taken in the composite grid sample one can use statistical …

Quantification of gene expression in single cells
… Thus, the geometric--and not the commonly used arithmetic--mean value is the appropriate measure of average expression level. In beta-cells, insulin mRNA levels were increased in response to glucose stimulation; an effect due to an increased fraction of cells with high expression. The insulin …

Impacts of diet inversion on voluntary intake, digesta and fecal composition, and bacterial community composition in rumen of cattle fed tropical forage-based diets
… using the unweight pair group method with arithmetic mean. Stabilization of the voluntary intake, ruminal digesta, fecal excretion and composition, and rumen fermentation profile was achieved within 9-13, 9- 14, 6-13, and 4-11 days after diet inversion, respectively. The bacterial community …

Evaluating the Sensitivity of the Auckland Pavement Polishing Device and Analysis of Aggregate Microtextural Wear
… height of microtexture parameters (such as Root Mean Square Height – Sq and Arithmetic Mean Height – Sa) are not suitable for analysing the microtextural wear. In contrast, the Root Mean Square Slope (Sdq) and Arithmetic Mean Summit Curvature (Ssc), which measure the shape of texture, are …
