This paper presents a fully automatic method addressing tree mapping and parameter extraction (tree position, stem diameter at breast height, stem curve, and tree height) from terrestrial laser scans ...
SEA OIL SPILL DETECTION USING SELF-SIMILARITY PARAMETER OF POLARIMETRIC SAR DATA
Oil Spill Detection PolSAR Image Self-Similarity Parameter Polarimetric Features Look-alikes Remote Sensing
2018/5/15
The ocean oil spills cause serious damage to the marine ecosystem. Polarimetric Synthetic Aperture Radar (SAR) is an important mean for oil spill detections on sea surface. The major challenge is how ...
Permeability as an important parameter for radon risk classification of foundation soils
permeability radon soil gas transfer factor
2015/9/10
Permeability of soils and rocks for gases is one of the main parameters for final radon risk classification of building
sites. For the improvement of the method for radon risk classification it is re...

2016/5/12
Five hundred and forty crossbred (Korean native black pig×Landrace) F2 were selected at a commercial pig farm and then divided into six different coat color groups: (A: Black, B: White, C: Red, D: Whi...
An operational approach for estimating surface vapor pressure with satellite-derived parameter
Haihe river basin surface vapor pressure precipitable water vapor
2011/1/12
Surface vapor pressure (SVP) is a highly significant variable for physically based crop growth simulating and crop yield modeling. Regional spatially representative data of observed SVP are not curren...
Comparison of daubechies wavelets for hurst parameter estimation
Daubechies wavelets fractional gaussian noise hurst estimation vanishing moment
2010/3/17
Time scale dependence on the working nature of wavelet analysis makes it a valuable tool for Hurst parameter estimation. Similar to other wavelet-based signal processing applications, the selection of...
Building linear parameter varying models using adaptation, for the control of a class of nonlinear systems
Linear parameter varying (LPV) systems nonlinear systems adaptive systems self-scheduling
2010/3/17
In this paper a novel method is proposed for constructing linear parameter varying (LPV) system models through adaptation. For a class of nonlinear systems, an LPV model is built using its linear part...

state-space methods power system transients Transmission line modeling
2010/3/17
In this paper, a distributed-parameter state variable approach is used to calculate transients on transmission lines based on the concept of travelling waves. The method of characteristics for lossles...
Is the parameter electron transport rate useful as a predictor of photosynthetic carbon assimilation rate?
Electron transport rate photosynthetic carbon assimilation rates estimated A value biochemical model field-measured A-ETR relation
2009/3/12
We compared the photosynthetic carbon assimilation rate (A) and the simultaneously measured electron transport rate (ETR) through photosystem II in order to examine the reliability of the A estimation...
Comparison of Parameter Estimation Methods for the Three-Parameter Generalized Pareto Distribution
three-parameter generalized Pareto distribution moments probability-weighted moments maximum likelihood principle of maximum entropy least squares
2009/1/12
The generalized Pareto distribution, which is a special case of both exponential and Wakeby distribution, has good potential for the analysis of flood peaks because of its inherent properties. In this...
