OPTIMIZING RADIOMETRIC PROCESSING AND FEATURE EXTRACTION OF DRONE BASED HYPERSPECTRAL FRAME FORMAT IMAGERY FOR ESTIMATION OF YIELD QUANTITY AND QUALITY OF A GRASS SWARD
Hyperspectral Photogrammetry Calibration Feature Estimation
2018/5/15
Light-weight 2D format hyperspectral imagers operable from unmanned aerial vehicles (UAV) have become common in various remote sensing tasks in recent years. Using these technologies, the area of inte...
THE POTENTIAL OF DISCRETE RETURN, SMALL FOOTPRINT AIRBORNE LASER SCANNING DATA FOR VEGETATION DENSITY ESTIMATION
laser scanning correlation point cloud forestry land cover
2015/8/13
We evaluate the potential of deriving a vegetation leaf area index (LAI) from small footprint airborne laser scanning
data. Based on findings from large area histograms of discrete laser return...
Trace Element Estimation – Methods & Clinical Context
Atomic Absorption Spectrophotometer ICP-MS Stripping Voltameter Colorimetry Electro Thermal Vaporization Neutron Activation Analysis Laser Microprobe Mass Analysis
2015/8/5
Understanding the effects of trace metals on human health is as complex as it is fascinating. As mentioned earlier, the high concentrations may prove toxic, as also, depletion in the concentration of ...

In this paper,a systematic study of quantum phase transition within U(5) \leftrightarrow SO(6) limits is presented in terms of infinite dimensional Algebraic technique in the IBM framework. Energy lev...
Ratio Estimation in SIMS Analysis
secondary ion mass spectrometry, ratio, isotope measurement, statistics,bias
2011/9/9
The determination of an isotope ratio by secondary ion mass spectrometry (SIMS) traditionally involves averaging a number of ratios collected over the course of a measurement. We show that this method...

2010/12/20
We explore the precision with which the Einstein Telescope (ET) will be able to measure the
parameters of intermediate–mass–ratio inspirals (IMRIs), i.e., the inspirals of stellar mass compact object...
Estimation of compact binary coalescense rates from short gamma-ray burst redshift measurements
Estimation of compact binary coalescense rates short gamma-ray redshift measurements
2010/12/21
Short gamma-ray bursts are believed to originate from the merger of two compact objects. If this scenario is correct, these bursts will be accompanied by the emission of strong gravitational waves, de...
