The Physics of the Retograde Motion of the Electric Arc
IEEE Transactions on Plasma Science, 1981The retrograde motion of the cathodic arc attachment point in a transverse magnetic field is examined and is attributed to the asymmetrical confinement of the cathode spot plasma which results from the asymmetrical combination of the self and applied magnetic fields.

The arguments developed in this chapter concern what one might call, in its widest sense, the physical “drives” of eidetic motion. As with every other aspect of the eidetic function, the motion of eidetic subsystems may be viewed from different points.

Uncertainty, Variability, and Earthquake Physics in Ground‐Motion Prediction Equations
, 2017Residuals between ground‐motion data and ground‐motion prediction equations (GMPEs) can be decomposed into terms representing earthquake source, path, and site effects.

By changing only the playback timing of a motion sequence, an animator can achieve a variety of effects that alter our perception of an event. In some scenarios, it may be important to consider physical properties of the motion when retiming (e.g., to preserve physical plausibility). However, existing retiming solutions can be quite time consuming when

THE PHYSICS OF TROPICAL CYCLONE MOTION
Annual Review of Fluid Mechanics, 2005▪ Abstract This article reviews our current understanding of the physical mechanisms governing the movement of a tropical cyclone. In a barotropic framework, a tropical cyclone is basically “steered” by the surrounding flow but its movement is modified by the Coriolis force (referred to as the beta effect) and the horizontal vorticity gradient of the

Inertial and Accelerated Motion in Spacetime Physics
2021Employing Minkowski’s program for regarding physics as geometry of the real spacetime produces spectacular results – it explained the principle of inertia, the principle of relativity (including the constancy of the speed of light), why acceleration is absolute in both special and general relativity, that absolute acceleration is a manifestation of an ...

Optimal robot motions for physical criteria
Journal of Robotic Systems, 2001AbstractThis paper presents an optimization‐based framework for emulating the low‐level capabilities of human motor coordination and learning. Our approach rests on the observation that in most biological motor learning scenarios some form of optimization with respect to a physical criterion is taking place.

The conceptualization of cases of physical motion
European Journal of Psychology of Education, 1989The question addressed in the present article concerns the contextual character of students’ conceptions of cases of psysical motion. An interview investigation with students following the mechanical engineering line of study at Chalmers University of Technology, Goteborg, Sweden was carried out during the students’ first year of study, before and ...
