Semi-Empirical Models and Revision of Predicting Approaches of Tree Aboveground Biomass Assessments
biomass allometry a and B scalar coefficients independent physical and biological parameterization wood specific gravity form factors checking the consistency of biomass equations
2023/12/4
Tree aboveground biomass (e.g., bole, branches, and foliage), M, plays key roles in forest management as it is the basis for evaluating the sink and flux of, for example, carbon and nitrogen, stand pr...
3d physical vs empirical models for stereo-processing hr images: examples with ikonos and quickbird
Photogrammetry Ikonos QuickBird Stereoscopic DEM/DTM Accuracy
2015/9/1
Elevations for digital surface model (DSM) generation were extracted from different stereo high-resolution (HR) imag...
Erosion Predictions by Empirical Models in a Mountainous Watershed in Nepal
Erosion Predictions Empirical Models Mountainous Watershed Nepal
2015/8/14
Soil erosion is a crucial problem in Nepal where more than 80% of the land area is mountainous. In this study, two commonly used empirical soil erosion models, Revised Universal Soil Loss Equation (RU...
Beyond Testing: Empirical Models of Insurance Markets
asymmetric information adverse selection
2015/7/17
We describe recent advances in the empirical analysis of insurance
markets. This new research proposes ways to estimate individual
demand for insurance and the relationship between prices and
insur...
Empirical Models of Imperfect Competition: A Discussion
Auction entry price competition estimation

Dark Matter Halos: The Dynamical Basis of Effective Empirical Models
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/29
We investigate the dynamical basis of the classic empirical models (specifically, Sersic-Einasto and generalized NFW) that are widely used to describe the distributions of collisionless matter in gala...
General empirical models for estimating nutrient load limits for Florida’s estuaries and inland waters
General empirical models nutrient load limits Florida’s estuaries inland waters
2014/4/16
We developed empirical models that can predict maximum allowable, nutrient loading rates or load limits (LM)for maintenance of mesotrophy in Florida’s fresh and estuarine waters. Waterresidence time (...
Rockfall travel distance analysis by using empirical models (Solà d'Andorra la Vella, Central Pyrenees)
Rockfall travel distance analysis empirical models
2009/12/31
In total, data from twenty small rockfalls have been gathered which reveal an amount of a hundred individual fallen rock blocks. The data acquired has been used to check the reliability of the main em...
Comparison of empirical models with intensively observed data for prediction of salt intrusion in the Sumjin River estuary, Korea
salt intrusion Sumjin River estuary
2009/7/22
Performance of empirical models has been compared with extensively observed data to determine the most suitable model for prediction of salt intrusion in the Sumjin River estuary, Korea. Intensive mea...
Empirical Models for the Correlation of Monthly Average Daily Global Solar Radiation with Hours of Sunshine on a Horizontal Surface at Karachi, Pakistan
solar radiation Hours of Sunshine
2010/4/12
A new set of constants for Angstrom-type correlation of first and second order, to estimate monthly average daily global solar radiation, has been obtained employing sunshine hours data recorded at Ka...
