Breakdown process on rod–rod air gap under oscillating lightning impulse voltage

High Voltage, 2020
This study presents the discharge process on rod–rod electrodes under oscillating lightning impulse voltage. For this purpose, a measurement system has been developed to record the discharge currents at both rod electrodes simultaneously and to ...

Study the effect of Pitch size When the number of rings of the second air gaps on the dispersion profile of Photonic Crystal Fibers

Tikrit Journal of Pure Science, 2023
The need for a fibre optics working in the visible part of the electromagnetic spectrum has led to the development of new kind of fibre optics called photonic crystal fibre (PCF).In this paper we have investigate the effect of the pitch distance Λ as a ...

Simulation of positive streamer propagation in an air gap with a GFRP composite barrier

High Voltage, 2021
The puncture of glass fibre reinforced polymer (GFRP) laminate is a primary damage pattern of wind turbine blades due to lightning strikes. A numerical simulation model of positive streamer propagation in a needle‐to‐plate air gap with a GFRP laminate is

Air Gap Penetration

International Journal of Scientific Research in Computer Science, Engineering and Information Technology, 2019
The issue of data security is very paramount for any organization now a day So through this project we will show how an attacker can steal data from the air gapped channels and also provide some measures in order to protect data from such type of attacks.

Analytical investigation of the armature current influence on the torque and radial force in eccentric consequent‐pole PM machines

IET Electric Power Applications, 2021
In this work, the electromagnetic torque and the unbalanced magnetic force (UMF) in eccentric consequent pole PM (CPPM) machines are investigated. For this investigation, in the first part of the paper, an exact analytical model is provided for the CPPM ...

Flux concentrated doubly salient linear permanent magnet machine

The Journal of Engineering, 2019
Different topologies of Vernier permanent magnet (PM) machines have been proposed for direct drive low-speed applications due to their high thrust and power density. However, this type of machine can suffer from low power factor (PF).

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
