Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Solving an equation means finding the value or values for which the two expressions on each side of the equals sign are equal. One of the most common methods used to solve equations is the balance ...

Abstract: For a weakly nonlinear system described by Volterra series, if the nonlinear differential equation (NDE) model of the system is unique, the nonlinear auto-regressive with exogenous input ...

A number machine is a way of writing rules using a flow diagram. The equation \(3j - 6 = 9\) can be shown on a number machine by writing out the functions that have been applied to \(j\) in the order ...

Abstract: This article presents the controlling of non-linear system with artificial intelligence (AI) technique. The non- linear system is represented by second order function and genetic algorithm ...

Can a cloud-based vision model compete with the big players? We put Qwen3-VL through 7 rigorous tests to find out.

A study suggests that the first of seven key pyramids in Egypt, the Step Pyramid of Djoser, was built using a hydraulic lift. Dated to about 4,500 years ago, this would move up the introduction of ...

This project contains a complete, hackathon-ready AI-first system for automatically checking the relevance of a resume against a job description. Set your API key: The application requires an API key ...

Oct. 7, 2025 — An international team has confirmed that large quantum systems really do obey quantum mechanics. Using Bell’s test across 73 qubits, they proved the presence of genuine quantum ...
