A 2-D process-based model for suspended sediment dynamics: a first step towards ecological modeling
TL;DR: In this paper, a robust sediment transport model is developed to assess sediment dynamics and their related ecological parameters over a range of spatial and temporal scales, which can be used as the base model for a chain of ecological models assessing the impact of climate change and management scenarios.
Impacts of topography change on saltwater intrusion over the past decade in the Changjiang Estuary
TL;DR: In this article, a well-validated 3D numerical model was used to simulate and analyze the residual water and salt transport, water diversion ratio (WDR) in bifurcated channels and water resources in the Changjiang Estuary in 2007 and 2017.

Data-driven analysis on ultimate axial strain of FRP-confined concrete cylinders based on explicit and implicit algorithms
TL;DR: The data-driven Bayesian probabilistic and machine learning prediction models (i.e., back-propagation artificial neural network, multi-gene genetic programming and support vector machine) with high accuracy are presented with outstanding predictive performance.

Spatial Models of Northern Bobwhite Populations for Conservation Planning
TL;DR: In this paper, the authors modeled the spatial distribution of northern bobwhite populations using landscape characteristics derived from 1992 National Land Cover Data and bird detections, from 1990 to 1994, along 10-stop Breeding Bird Survey route segments.

Variations of Box Plots
TL;DR: Box plots as mentioned in this paper display batches of data and use five values from a set of data: the extremes, the upper and lower hinges (quartiles), and the median, commonly used for exploratory data analysis and in preparing visual summaries.

An improved equation for estimating long-wave radiation from the atmosphere
TL;DR: In this paper, an equation that predicts downcoming long-wave radiation from clear skies on the basis of screen air temperature and vapor pressure has been developed, which fits measured data at extremes of temperature and humidity better than existing equations, and exhibits comparable accuracy at intermediate values.

An Empirical Method for the Spatial Interpolation of Monthly Precipitation within California
Cort J. Willmott,Donald E. Wicks +1 more
TL;DR: In this paper, an empirical method for interpolating monthly precipitation totals within California is described and evaluated using 120 monthly precipitation total observed from 1961-1970 at each of 90 randomly selected stations in California and a P-mode principal components analysis of a co-variance matrix, four independent sources of precipitation variability were identified and quantitatively paraphrased.

M.A. Atwater,J.T. Ball +1 more
TL;DR: In this article, a numerical model based on standard meteorological data, as described above, can be used to extend the data base for design purposes, and the model is used to compute the amount of direct solar flux.

Fitting straight lines when both variables are subject to error.
TL;DR: In this paper, the maximum likelihood estimators of α and β under functional and structural models are discussed, and the least square procedure is also considered, leading to a quadratic equation which can be solved to give an estimate of β.
