Abstract: Estimating stochastic gradients is pivotal in fields like service systems in operations research. The classical method for this estimation is the finite-difference approximation, which ...

The‍‌‍‍‌‍‌‍‍‌ Burmese python is among the largest snakes globally and originates from a few areas in South and Southeast Asia, such as India, southern China, and the Malay Peninsula. The python is now ...

A new approach in the finite difference framework is developed, which consists of three steps: choosing the dimension of the local approximation subspace, constructing a vector basis for this subspace ...

Abstract: Differential microphone arrays (DMAs) have demonstrated great advantages in high-fidelity acoustic signal acquisition and enhancement due to their capability to capture both the acoustic ...

It can be easy to confuse the two, but there’s a difference, and it has to do with your internet speeds. Joe Supan is a senior writer for CNET covering home technology, broadband, and moving. Prior to ...

ABSTRACT: This paper presents a comprehensive numerical study of the two-dimensional time-dependent heat conduction equation using the Forward Time Centered Space (FTCS) finite difference scheme. The ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

There are four different Apple Pencils and each one has slightly different capabilities. After reviewing them all, we're here to help you figure out which one will work best for you. I’m PCMag’s ...

I've been a contributing editor for PCMag since 2011. Before that, I was PCMag's lead audio analyst from 2006 to 2011. Even though I'm a freelancer now, PCMag has been my home for well over a decade, ...
