Mitigation of numerical Cerenkov radiation and instability using a hybrid finite difference-FFT Maxwell solver and a local charge conserving current deposit [PDF]
Computer Physics Communications, 2015 A hybrid Maxwell solver for fully relativistic and electromagnetic (EM) particle-in-cell (PIC) codes is described. In this solver, the EM fields are solved in $k$ space by performing an FFT in one direction, while using finite difference operators in the

High-concurrency tri-mode memristor-based ordinary differential equation solver [PDF]
Nature CommunicationsOrdinary differential equations (ODEs) are widely used in science, engineering, and mathematics, but their numerical solution on traditional Von Neumann hardware is time- and energy-consuming, especially for high-order ODEs.

SIAM Journal on Scientific Computing, 2022 Gopal and Trefethen recently introduced "lightning solvers" for the 2D Laplace and Helmholtz equations, based on rational functions with poles exponentially clustered near singular corners. Making use of the Goursat representation in terms of analytic functions, we extend these methods to the biharmonic equation, specifically to 2D Stokes flow ...

Simulation of gas flow around the scoop in a two-dimensional (r-θ) centrifugal rotor using the direct Monte Carlo method [PDF]
مجله علوم و فنون هستهای, 2023 One of the driving factors for creating axial flow inside the gas centrifuge rotor to increase the separation performance is the scoop. Due to the exposure of the scoop to the high Mach gas flow, the flow will be shocked, and strong gradients will occur ...

Coordinating with a “Problem Solver” [PDF]
Management Science, 2019 A “problem solver” (PS) is an agent who when interacting with other agents does not “put himself in their shoes” but rather chooses a best response to a uniform distribution over all possible configurations consistent with the information he receives about the other agents’ moves.

Benchmarking UAQ Solvers [PDF]
Proceedings of the 25th ACM Symposium on Access Control Models and Technologies, 2020 The User Authorization Query (UAQ) Problem is key for RBAC systems that aim to offer permission level user-system interaction, where the system automatically determines the roles to activate in order to enable the requested permissions. Finding a solution to a UAQ problem amounts to determining an optimum set of roles to activate in a given session so ...
