What is the Velocity of the Electromagnetic Field? [PDF]

open access: yesJournal of Nonlinear Mathematical Physics, 1998
A new definition for the electromagnetic field velocity is proposed. The velocity depends on the physical fields.

A Monte-Carlo error analysis for basal sliding velocity calculations [PDF]

open access: yes, 2006
Since glacier beds are mostly inaccessible, numerical inversion of the surface velocity field provides a valuable method for calculating the basal shear stress and sliding velocity. However, previous theoretical studies (limited either to planar slabs or

Investigation into the selection of viewing configurations for three-component planar Doppler velocimetry measurements. [PDF]

open access: yes, 2007
A method for the calculation of three orthogonal velocity components in planar Doppler velocimetry (PDV) using four or more measured velocity components (to the three typically used) is presented.

Effects of Spatiotemporal Filtering on the Periodic Signals and Noise in the GPS Position Time Series of the Crustal Movement Observation Network of China

open access: yesRemote Sensing, 2018
Analysis of Global Positioning System (GPS) position time series and its common mode components (CMC) is very important for the investigation of GPS technique error, the evaluation of environmental loading effects, and the estimation of a realistic and ...

Energy velocity and reactive fields [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
Conventional definitions of ‘near fields’ set bounds that describe where near fields may be found. These definitions tell us nothing about what near fields are, why they exist or how they work. In 1893, Heaviside derived the electromagnetic energy velocity for plane waves.

FIELD MEASUREMENTS OF NEARSHORE VELOCITIES

open access: yesCoastal Engineering Proceedings, 1974
Two component electromagnetic flowmeters are being used as the basis of an apparatus to measure nearshore velocities on natural beaches. The flowmeters are mounted on free standing tripods, 1 m. base side and 0.3 m. high, to measure the two components of horizontal flow, and have been used in depths of up to 4 m. and up to 150 m.

RETRACTED ARTICLE: Velocity and shear stress for an Oldroyd-B fluid within two cylinders

open access: yesBoundary Value Problems, 2016
This paper aims to explore the possible solutions for the movement of an Oldroyd-B fluid placed under certain conditions, i.e. the fluid is present within two cylinders, which are coaxial and oscillating within.
