Abstract: An efficient implementation of low order surface impedance boundary conditions (SIBCs) for the finite-difference time-domain (FDTD) method is presented. The surface impedance function of a ...

In this work a Finite-Difference Frequency-Domain (FDFD) propagation method for complex urban environments is proposed. The formulation starts from the discretization of the Helmholtz equation for the ...

Difference in differences methods have become very popular in applied work. This paper provides a new method for inference in these models when there are a small number of policy changes. This ...

Abstract: In this article, we propose a redundant fault-tolerant and boundary constraint control in the framework of adaptive method, the neural network approximation, and the barrier Lyapunov ...

One of the deepest ambitions in modern physics is understanding how the fabric of space and time could emerge from fundamental quantum degrees of freedom to establish a quantum theory of gravity.

For months, the phrase "quantum advantage" has appeared in TechTimes as a goal — something IBM was targeting, something D-Wave claimed and then lost to a laptop, something the industry was chasing ...

A finite element model for solving ocean circulation forced by winds and atmospheric heat fluxes is presented. It is vertically integrated 1 1/2 layer model which solves the motion and continuity ...

Update: I will be graduating soon and I am looking for postdoc/full time research positions in reinforcement learning and more broadly in machine learning, motivated by a practical application. Prior ...

Unofficial CME FedWatch — FOMC rate-change probabilities in one line of Python. The only open-source FedWatch that actually works out of the box. No data prep, no API keys, no Selenium. # Default: ...

Penalty function and perturbed lagrangian methods -- 3.13 Least squares approximations -- 3.14 Concluding remarks -- finite difference and boundary methods -- 3.15 Problems -- 4. 'Standard' and ...

This can be useful to calculate derivatives using finite differences if required. The encoding further has the property that one can just move the value u (or v) on a subpatch by adding du (or dv) to ...
