The linear cable theory has been applied to a modular structure consisting of n repeating units each composed of two subunits with different values of resistance and capacitance. For n going to infinity, i.e., for infinite cables, we have derived analytically the Laplace transform of the solution by making use of a difference method and we have inverted it by means of a numerical procedure. The...

where is the membrane time constant, is the membrane space constant, and V is the membrane potential. This equation describes the propagation of electricity along a core conductor, as some of the current escapes through a nonperfect insulator to an infinite external conductor. This cable equation was successfully adapted from the underwater telegraph to axons (4) and later to dendrites (9–12) a...

Abstract. Marine electromagnetic (EM) signals largely depend on three factors: flow velocity, Earth's main magnetic field, and seawater's electrical conductivity (which depends the local temperature salinity). Because of this, there has been recent interest in using marine EM to monitor study ocean circulation. Our utilizes voltage data from retired seafloor telecommunication cables Pacific Oce...

Since the temperature distribution, electric field distribution and steady-state current-carrying capacity of HVDC (high-voltage direct-current) cables affect each other, should be taken into account when calculating capacity. In addition, in actual operation submarine cables, not only their own characteristics but also impact laying conditions on cable considered. this paper, COMSOL Multiphysi...

A cable configuration technique for the balance of current distribution in parallel-connected single-core cables is proposed. Based on the mutual inductance theorem, a closed form solution for the calculation of current distributions in parallel-connected cables is first derived. To compare the performances of different cable configurations, two indices are introduced, one for the power losses ...

Three cases of suicides due to electricity, which happened outside the bathtub, are presented. In favour of suicide there spoke farewell letters, the situation of discovery or known depressive personality changes. In all three cases it was about male persons at the age of 19, 30 and 50. Low-voltage electricity was used. The locations chosen for the employed electric cables were: right wrist/lef...

The nearly 21-year-old Jiujiang Bridge, which is suffering from uneven line shape, constant great downwarping of the main beam and cracking of the box girder, needs reinforcement and cable adjustment. It has undergone cable adjustment for twice with incomplete data. Therefore, the initial internal force state of the Jiujiang Bridge is identified as the key for the cable adjustment project. Base...

Concerns regarding possible transverse instabilities in RHIC and the SNS pointed to the need for measurements of the transverse coupling impedance of ring components. The impedance of the RHIC injection and abort kicker was measured using the conventional method based on the S21 forward transmission coefficient. A commercial 450 Ω twin-wire Lecher line were used and the data was interpreted via...

The cooperative action of neurons and glia generates electrical fields, but their effect on individual neurons via ephaptic interactions is mostly unknown. Here, we analyze the impact of spatially inhomogeneous electric fields on the membrane potential, the induced membrane field, and the induced current source density of one-dimensional cables as well as morphologically realistic neurons and d...
