Investigation of the relation of decay time differences and α-β ratios for newly developed scintillators
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Recently we found the decay times were different between a particles and γ photons for recently developed scintillators. We also noticed that α-β ratios were different for these scintillators. We expect that there might be...

Investigation of the Relation of Decay Time Differences and $\alpha-\beta$ Ratios for Newly Developed Scintillators
2019 Edition, Volume 66, November 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Recently, we found that the decay times between $\alpha $ particles and $\gamma $ photons were different for the recently developed scintillators. We also noticed that $\alpha - \beta $ ratios were different for these...

A Spherical FDTD Numerical Dispersion Relation Based on Elemental Spherical Wave Functions
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The numerical dispersion relation for the finite-difference time-domain method in three-dimensional spherical coordinates is derived. Derivation is based on matching spherical wave functions and results in a relation that is equally valid in...

FDTD Method for Wave Propagation in Havriliak-Negami Media based on Fractional Derivative Approximation
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A finite-difference time-domain (FDTD) method for simulating wave propagation in Havriliak-Negami (H-N) dispersive media is presented. In an H-N medium, the time-domain polarization relation involves a fractional differential operator, whose analytical...

Systematic Study on Aluminum Composition Nonuniformity in Aluminum Gallium Nitride Metal-Semiconductor-Metal Photodetectors
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The influence of aluminum composition (Al%) nonuniformity on AlGaN metal-semiconductor-metal photodetectors was thoroughly studied on a device level. The Al% fluctuation was precisely measured by X-ray photoelectron spectroscopy and mapped by energy dispersive...

Decision-Making Models Based on Incomplete Hesitant Fuzzy Linguistic Preference Relation With Application to Site Selection of Hydropower Stations
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This article proposes two decision-making models in an incomplete fuzzy hesitant linguistic environment and applies them to address the site selection problems for hydropower stations. For better depicting a decision maker's judgments under uncertainty, based on...

Systematic Relation of Estimated Travel Speed and Actual Travel Speed
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Estimated travel speed based on spot speed measurements from detectors has been used as a proxy to actual travel speed. Recently, actual travel speeds become available as vehicles with onboard electronic devices provide actual section travel times. As a result, two different speeds can be estimated...

Triplet-Based Semantic Relation Learning for Aerial Remote Sensing Image Change Detection
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This letter presents a novel supervised change detection method based on a deep siamese semantic network framework, which is trained by using improved triplet loss function for optical aerial images. The proposed framework can not only extract features directly from image pairs which...

High-Order Symplectic Compact Finite-Different Time-Domain Algorithm for Guide-Wave Structures
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Based on higher order symplectic integrator temporal derivatives and compact spatial derivatives, a new high-order symplectic compact finite-difference time-domain (FDTD) algorithm is proposed. The numerical stability criteria and dispersion relation are...

Synchronization Analysis of Two-Time-Scale Nonlinear Complex Networks With Time-Scale-Dependent Coupling
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, a time-scale-dependent coupling scheme for two-time-scale nonlinear complex networks is proposed. According to this scheme, the inner coupling matrices are related to the fast dynamics of individual subsystems, but are no longer...
