NEW ALGORITHM FOR SUB-PIXEL BOUNDARY MAPPING
Mixed Pixel Endmember Spatial Pattern Sub-Pixel Boundary Mapping
2015/8/31
Remotely sensed images often contain a combination of both pure and mixed pixels. Analysis and classification of remotely sensed
imagery used to provide information on the spatial pattern of land co...
Choice of the perfectly matched layer boundary condition for frequency-domain Maxwell’s equations solvers
Maxwell’s equations Perfectly matched layer Finite-difference frequency-domain method
2015/8/7
We show that the performance of frequency-domain solvers of Maxwell’s equations is greatly affected by the kind of the perfectly matched layer (PML) used. In particular, we demonstrate that using the ...
Stability of Nonlinear Te Surface Waves along the Boundary of Left-Handed Material
Nonlinear Waves Wave-Guides Dispersion Relation Left-Handed Material Growth Rate Stability
2013/1/30
This paper is concerned with the stability characteristics of nonlinear surface waves propagating along a left-handed substrate (LHM) and a non-linear dielectric cover. These characteristics have been...
Asymptotic Principal Values and Regularization Methods for Correlation Functions with Reflective Boundary Conditions
asymptotic principal values correlation functions singular integrals
2011/4/21
We introduce a concept of asymptotic principal values which enables us to handle rigorously singular integrals of higher-order poles encountered in the computation of various quantities based on corre...
Pure rotational Raman lidar with fiber Bragg grating for temperature profiling of the atmospheric boundary layer
pure rotational Raman lidar fiber Bragg grating
2011/5/6
A new pure rotational Raman lidar (PRRL) system at a wavelength of 532.25 nm has been designed for profiling the atmospheric temperature of the planetary boundary layer. A newly compact spectroscope s...
Skew ray tracing and error analysis of optical elements with ellipsoid boundary surfaces
skew ray tracing error analysis
2011/5/6
Utilizing a ray tracing approach based upon Snell’s optical laws and a 4×4 homogeneous coordinate transformation matrix, this study conducts a systematic analysis of the errors induced in the paths of...
X-ray carpal-bone image boundary feature analysis using region statistical feature based level set method for skeletal age assessment application
carpal-bone radiograph skeletal age (estimation) anisotropic diffusion filter
2011/4/26
Skeletal age assessment is one of the important applications of hand radiography in the area of pediatric radiology. Feature analysis of the carpal-bones can reveal the important information for skele...
Absorbing Boundary Conditions for FDTD Simulations of Photonic Crystal Waveguides
Absorbing Boundary Conditions FDTD Simulations Photonic Crystal Waveguides
2015/8/12
We present a novel numerical scheme for the reduction of spurious reflections in simulations of electromagnetic wave propagation in photonic crystal waveguides. We use a distributed Bragg re@...
