Abstract:
In India, the implementation of Gas Insulated Substation (GIS) has been accelerated for two decades. In the case of GIS, the electric and magnetic field estimation is very important because of the shorter distances of bus bars and line sections. Several others have given the estimation of electric and magnetic fields by solving nonlinear differential equations using numerical techniques. In this paper, the advanced simulation tools ELECNET and MAGNET have been used to estimate these fields. A typical 245k V GIS is considered for Modeling and simulation.

Background: Transcranial electrical stimulation (tES) generates an electric field (or current density) in the brain through surface electrodes attached to the scalp. Clinical significance has been demonstrated, although with moderate and heterogeneous results partly due to a lack of control of the delivered electric currents. In the last decade, computational electric field analysis has allowed the estimation and optimization of the electric field using accurate anatomical head models. This review examines recent tES computational studies, providing a comprehensive background on the technical

Abstract:
In comparison to high-voltage alternating current (HVAC) cable systems, high-voltage direct current (HVDC) systems have several advantages, e.g., the transmitted power or long-distance transmission. The insulating materials feature a non-linear dependency on the electric field and the temperature. Applying a constant voltage, space charges accumulate in the insulation and yield a slowly time-varying electric field. As a complement to measurements, numerical simulations are used to obtain the electric field distribution inside the insulation. The simulation results can be used to design HVDC ca

Testing of electronic devices is an integral part of the technological process of any manufacturer of such equipment. In this case, an electronic device is understood as an energy-intensive unit such as a mobile phone, data center or spacecraft. One of the key stages of testing is to identify the effect of electric fields on various electronic components of the device. This stage often requires making a mock-up of some part of an unfinished device in order to fix interference with special equipment. This requires time, financial and human resource costs.

Well-posedness of the system is studied by its reformulation as a first order in space and time differential system with help of an elliptic lifting operator.

Abstract Objective. Metal implants impact the dosimetry assessment in electrical stimulation techniques. Therefore, they need to be included in numerical models. While currents in the body are ionic, metals only allow electron transport. In fact, charge transfer between tissues and metals requires electric fields to drive electrochemical reactions at the interface. Thus, metal implants may act as insulators or as conductors depending on the scenario. The aim of this paper is to provide a theoretical argument that guides the choice of the correct representation of metal implants in electrical m

The global reliance on electric vehicles (EVs) has been rapidly increasing due to the excessive use of fossil fuels and the resultant CO2 emissions. Moreover, EVs facilitate using alternative energy sources, such as energy storage systems (ESSs) and renewable energy sources (RESs), promoting mobility while reducing dependence on fossil fuels. However, this trend is accompanied by multiple challenges related to EVs’ traction systems, storage capacity, chemistry, charging infrastructure, and techniques.

Abstract:
Abstract Current nondestructive inspection (NDI) techniques, such as visual inspection, ultrasonic testing, and eddy current testing, do not adequately detect the early stages of hidden corrosion under paint in critical structures such as airframes. This paper proposes a sensor system that uses meandering winding magnetometers (MWMs) and interdigital electrode dielectrometers (IDEDs) to detect hidden corrosion under paint and to measure the depth of moisture within barrier paint coatings. The MWM uses magnetic fields and inductive coupling to measure profiles of the properties of conducting me

Abstract:
Abstract Chemical cleaning of industrial process equipment can result in corrosion of carbon and low alloy components. Predicting and monitoring of such corrosion is a critical aspect of the overall chemical cleaning project. Normally, laboratory qualification testing is performed to establish the expected corrosiveness of the process. Electrochemical techniques such as linear polarization resistance (LPR), electrical resistance (ER), zero resistance ammetry (ZRA), or electrochemical noise (ECN) are then used in the field during the cleaning to follow the corrosion on-line.

Abstract:
Abstract The development of an electric field cell lysis device for microfluidic applications will be presented. Detailed modeling of the electrode configuration for the optimization of the electric field has been performed. Device design and fabrication has been accomplished using traditional integrated circuit (IC) manufacturing techniques. As a result, murine lymphocytes have been lysed using several electrode configurations. The requisite electric field strength and pulse parameters for cell lysis were determined.

Abstract:
Abstract The brain is encased in the skull and suspended and supported by a series of three fibrous tissue layers: Dura mater, Arachnoid and Pia matter, known as the Meninges. Arachnoid trabeculae are strands of collagen tissues located in a space between the arachnoid and the pia matter known as the subarachnoid space (SAS). The SAS trabeculae play an important role in damping and reducing the relative movement of the brain with respect to the skull. The SAS is filled with cerebrospinal fluid (CSF), which is a colorless fluid that surrounds all over the brain inside the subarachnoid spaces. T

Abstract:
We discuss various numerical techniques for evaluating electric fields in strongly guiding rib-waveguide structures. We first demonstrate that the matrix beam propagation algorithm can be efficiently adapted to modal analysis in a form in which only a few field distributions are evolved in imaginary longitudinal distance. Subsequently, we consider longitudinally varying rib-waveguide elements. We introduce and compare the split-step fast-Fourier-transform, modified split-step fast-Fourier-trans form, split-operator finite-difference, real-space, and split-operator finite-element methods for so

Abstract:
Electric resistance welded (ERW) pipe has been used in the natural gas transmission industry for many years. The Department of Transportation (DOT) has recently expressed interest in the integrity of the weld seam in pipelines made from ERW pipe that was manufactured prior to 1970. Specifically, the DOT has requested that natural gas transmission and hazardous liquid pipeline operators determine whether or not their pipelines that meet this description require hydrostatic proof testing. The initial concern from the DOT was for seam weld selective corrosion, although reference has since been ma
