An alternating direction Galerkin method for a time-fractional partial differential equation with damping in two space dimensions

open access: yesAdvances in Difference Equations, 2017
In this paper, we propose an efficient alternating direction implicit (ADI) Galerkin method for solving the time-fractional partial differential equation with damping, where the fractional derivative is in the sense of Caputo with order in ( 1 , 2 ) $(1 ...

Climate change and perennial crop production: Evidence of yield impact and adaptation in California

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

Novel Second-Order Accurate Implicit Numerical Methods for the Riesz Space Distributed-Order Advection-Dispersion Equations

open access: yesAdvances in Mathematical Physics, 2015
We derive and analyze second-order accurate implicit numerical methods for the Riesz space distributed-order advection-dispersion equations (RSDO-ADE) in one-dimensional (1D) and two-dimensional (2D) cases, respectively.

EM Pulse Propagation Modeling for Tunnels by Three-Dimensional ADI-TDPE Method

open access: yesIEEE Access, 2020
The three-dimensional time domain parabolic equation (3D-TDPE) is derived to simulate the EM pulse propagation in straight, curved tunnels. Then the finite differential (FD) method is applied to accurately and flexibly describe the fine structures in the

Beyond Robodebt: Media Representations of Welfare and Fraud Before and After the Robodebt Royal Commission

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Australia's Robodebt scheme, an automated debt recovery program introduced in 2016, was exposed by the Robodebt Royal Commission (RC) as a serious failure of public administration and source of significant harm for thousands of Australians. Through a critical discourse analysis (CDA) of Australian news media, this study explores whether the RC'

Alternating-direction method for a mildly nonlinear elliptic equation with nonlocal integral conditions

open access: yesNonlinear Analysis, 2011
The present paper deals with a generalization of the alternating-direction implicit (ADI) method for the two-dimensional nonlinear Poisson equation in a rectangular domain with integral boundary condition in one coordinate direction.

k‐Selective Electrical‐to‐Magnon Transduction with Finite‐Element‐Resolved Sub‐Micron Nanoantennas

open access: yesAdvanced Physics Research, EarlyView.
We introduce a coupled finite‐element‐finite‐difference framework that links impedance‐matched nanoantenna geometries to propagating spin‐wave dynamics, capturing skin effects, proximity effects, and taper leakage beyond uniform‐current models. Applied to coplanar‐waveguide and stripline nanoantennas on yttrium‐iron‐garnet, the simulations achieve ...

An Iterative High-Accuracy ADI Method for the 3D Parabolic Equation

open access: yesInternational Journal of Antennas and Propagation, 2023
The alternating direction implicit parabolic equation (ADI-PE) method and the Crank–Nicolson parabolic equation (CN-PE) method have been widely used for solving the 3D parabolic equation (3D-PE) in radio wave propagation.

Developing a critical caste analysis within information science and technology: A research review: An annual review of information science and technology paper

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Caste—an ascriptive social hierarchy in South Asia and its diaspora—is a globalized phenomenon. Recent caste‐based discrimination, particularly in technology companies and anti‐caste efforts to address it, has compelled academia, policy, and the technology industry to better understand contemporary mechanics of caste.
