Abstract: The accurate measurement of the angular displacement and velocity of reaction wheels is necessary for attitude (orientation) control in space vehicles (satellites). In this paper, microwave, ...

Physics is a natural science that, compared to others, is less popular among the general population, both adults & children. However, awareness of the presence of physics in every corner of our ...

Consider the rotor of a gyroscope. The rotor is attached to a frame that is rotating about a fixed vertical axes with a constant rate of ω 1, and with the rotor rotating relative to that frame at a ...

Abstract: This paper addresses the problem of estimating the angular velocity given noisy attitude measurements for attitude control in small satellites. Based on contraction analysis, a set of global ...

We are aware that 'veganism' and the definition of it can be a hot topic. We created the non-vegan list keeping in mind that veganism in dietary terms, it denotes the practice of dispensing with all ...

Physicists have measured both the momentum and position of a particle without breaking Heisenberg’s iconic uncertainty principle. In quantum mechanics, particles don’t have fixed properties the way ...

Oct. 12, 2025 — A colossal northern asteroid impact billions of years ago likely shaped the Moon’s south polar region and explains its uneven terrain. Researchers found that the South Pole-Aitken ...
