On Earth, depending on where you are, the analemma can be at different angles, though it always traces out this ...

Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular ...

This paper considers the multi-dimensional motion patterns of a rotating object and presents methods to estimate its motion parameters, including the rotational direction, angular velocity, motion ...

Topological insulators are materials that are insulating in their interior but can support the flow of electrons on their surface. The underlying cause is time-reversal symmetry: their physics is ...

The module introduces the equations of motion for a rigid body aircraft and the aerodynamic forces and moments are then determined. Static and dynamic stability and response characteristics are ...

Learn about the fundamental concepts in mechatronic and robotic areas, including mathematics, intelligent system design, computing, control, electronics and embedded systems. Then go on to practical ...

In molecular dynamics (MD), the accessible time scales are limited by the necessity to choose sufficiently small time steps so that the fastest vibrations of the system can still be modeled. Mass ...

However, persistent directional motion is required for micromotors to perform useful work. Herein, through modeling and experiments, we demonstrate the general design strategy for single-component ...

This paper presents the development of the generalized d'Alembert equations of motion for application to mechanical manipulators with rotary joints. These equations, when applied to a robot arm, ...

Follow-up observations to see how much this giant exoplanet's gravity affects the orbital motion of the star revealed the mass of TOI-6894b. It's just 17 percent of the mass of Jupiter, suggesting an ...

“So we think this is the first observation of a superconductor that behaves as a magnet due to the electrons’ orbital motion, which is known as a chiral superconductor. It’s one of a kind. It is also ...
