Air Gap Penetration

open access: yesInternational 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.

Study on the influence of rainfall on the electric field distribution and switching impulse voltage of large-size sphere–plane gap

open access: yesThe Journal of Engineering, 2019
Previously, the research about the influence of rainfall on the discharge characteristics of the gap mainly focused on the severe non-uniform electric field gap such as rod–plane, rod–rod, or tower head of which the electrode size was generally small. As

Torque ripple reduction in homopolar poly-phase transverse flux machine

open access: yesThe Journal of Engineering, 2019
The problem of high ripple in output torque is inherent to switched reluctance and permanent magnet machines compared to conventional machines. Torque ripple is undesirable as it leads to increased audible noise, speed ripple, and fatigue.

Finned Tubular Air Gap Membrane Distillation

open access: yesMembranes, 2023
Finned tubular air gap membrane distillation is a new membrane distillation method, and its functional performance, characterization parameters, finned tube structures, and other studies have clear academic and practical application value. Therefore, the tubular air gap membrane distillation experiment modules composed of PTFE membrane and finned tubes

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

open access: yesHigh 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 ...

Surface micromachined mechanisms and micromotors [PDF]

open access: yes, 1991
Electric micromotors are sub-millimeter sized actuators capable of unrestrained motion in at least one degree of freedom. Polysilicon surface micromachining using heavily phosphorus-doped LPCVD polysilicon for the structural material, LPCVD silicon ...

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

open access: yesTikrit 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

open access: yesHigh 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

Gap deformation and classical wave localization in disordered two-dimensional photonic band gap materials

open access: yes, 2000
By using two ab initio numerical methods we study the effects that disorder has on the spectral gaps and on wave localization in two-dimensional photonic band gap materials.

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

open access: yesIET 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 ...
