Abstract: The unconditionally stable (US) Chebyshev (CS) finite-difference time-domain (FDTD) method is extended for solving the problems of long-time simulation or harmonic resonance using a ...

Health systems across the country are well past the pilot stage and deploying AI across clinical, operational and financial functions. CommonSpirit Health (Chicago) has approximately 250 active AI ...

Learning to play the piano has long been associated with rigid lessons, endless scales, and strict adherence to classical repertoire. Rarely has it been considered fun. But now, Payam Khastkhodaei ...

ABSTRACT: The nearly analytic discretization of the frequency-domain wave equation produces large-scale, sparse, and ill-conditioned linear system, which challenge conventional iterative solvers. To ...

The percentage of teachers who are using artificial intelligence-driven tools in their classrooms nearly doubled between 2023 and 2025, according to data from the EdWeek Research Center. In 2023, a ...

Compared to the conventional high-order staggered-grid finite-difference method (C-SFD), the time–space domain dispersion-relation-based high-order staggered-grid finite-difference method (TS-SFD) can ...

We use the parameters listed in (3) to generate data for options to verify our results from the European call option against the analytical solution given in (3) in order to confirm their accuracy.
