OPEC+ faces challenges in maintaining a backwardated market on anticipated stock builds and slowing demand. Global oil demand is projected to decrease by 230,000 bpd in Q4 2025, while non-OPEC+ supply ...

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 ...

This repository contains a comprehensive, step-by-step UAV design package using MATLAB, fully compiled into a single, well-organized Word document. It guides users through the entire fixed-wing UAV ...

Yaw rate and sideslip angle are critical indicators for evaluating vehicle handling stability. When a vehicle is driven at high speed, emergency steering by the driver may cause loss of control, ...

Existing approaches for tunnel face stability analysis usually apply for circular cross-sections and solutions for tunnel face stability evaluation with city gate cross-sections by kinematic approach ...

Princeton engineers improved remote-controlled aircraft performance by mimicking bird feathers. Adding rows of flaps to the wings enhances stability and reduces the risk of stalling, a dangerous ...

In order for the aircraft to be stable, the calculated coefficients must fall within a given range. In order to achieve roll static stability, the roll moment coefficient (Cl) must be negative, and ...

Predicting slope stability is important for preventing and mitigating landslide disasters. This paper examines the existing approaches for analyzing slope stability. There are several established ...
