Researchers in Spain reviewed six models used to calculate incidence angle modifier (IAM) losses in photovoltaic systems. They identified the Martín-Ruiz model as the most comprehensive, as it ...

A rediscovered formula is changing how we understand the hidden journeys of airborne particles. Researchers at the University of Warwick have created a straightforward new way to predict how ...

Is something happening in our solar system? An object from interstellar space, designated 3I/ATLAS, is not just passing ...

Abstract: In this brief, a global finite-time attitude control algorithm is proposed for flexible spacecraft without angular velocity measurement. First, a global finite-time observer is designed to ...
