Large parallel electric fields, currents, and density cavities in dispersive Alfvén waves above the aurora
[1] Large parallel electric fields (Ek > 10 mV/m) are sometimes observed with intense filamentary field-aligned currents (Jk > 10 mA/m 2 mapped to 100-km altitude) on transverse scales where kxc/wpe 1 above the auroral oval. The ratio of the transverse electric (Ex) and magnetic field (By) variations is approximately the local Alfvén speed and increases with decreasing transverse scale in a man...
متن کاملWaves on unsteady currents
Models for surface gravity wave propagation in the presence of currents often assume the current field to be quasi-stationary, which implies that the absolute wave frequency is time invariant. However, in the presence of unsteady currents or time-varying water depth, linear wave theory predicts a time variation of the absolute wave frequency and wavenumber . Herein, observations of wave frequen...
متن کاملELECTRIC CURRENT Effect of Electric Currents on Cells and Tissues
In the presence ol electrical currents, the body behaves like an electrochemical system. On the other hand, due to anatomical reasons such as the presence of membranes, it generates potential differences between different parts of the body. Therefore, when one considers the possibility of electrical currents acting upon the body, the end result will be the integration of the intrinsic currents ...
متن کاملElectric currents in infinite networks
In this survey, we will present the basic facts about conduction in infinite networks. This survey is based on the work of Flanders [5, 6], Zemanian [17], and Thomassen [14], who developed the theory of infinite networks from scratch. Here we will show how to get a more complete theory by paralleling the well-developed theory of conduction on open Riemann surfaces. Like Flanders and Thomassen, ...
متن کاملEstimation of Hydrodynamic Force on Rough Circular Cylinders in Random Waves and Currents (RESEARCH NOTE)
Most of the Codes of Practice (API, BSI, DnV, NPD) uses Morison's equation to estimate hydrodynamic loads on fixed and moving offshore structures. The significant difference in the prediction of the loads mainly arises from the assumption of the values of hydrodynamic coefficients. In this paper by analysing a full scale set of data in large KC's numbers collected from Delta Wave Flume in the N...
