Visualising gas heating from an RF plasma loudspeaker [PDF]

, 2010
In an electro-acoustic transduction mechanism, an ac modulation (here in the audio frequency range) of the electric field in an atmospheric pressure air plasma gives rise to a rapid increase in the gas temperature and dimensions of the gas volume.

Economic Viability of Photovoltaic Systems Providing Frequency Containment Reserve

Advanced Energy and Sustainability Research, EarlyView.
This article investigates the feasibility of photovoltaic (PV) systems providing frequency containment reserve (FCR) in the Netherlands. The economic analysis demonstrates that a PV plant can profitably participate in FCR without battery storage by maintaining an active power reserve.

Evaluation Of Lightning Current Parameters Using Measured Lightning Induced Voltage On Distribution Power Lines [PDF]

2019 11th Asia-Pacific International Conference on Lightning (APL), 2019
In this paper, an algorithm had been proposed to evaluate the lightning current parameters using measured voltage from overhead distribution lines based on lightning location obtained from lightning location system. Moreover, the performance of algorithm had been considered using different samples of induced voltage.

Advances in Triboelectric Nanogenerators With Rotating Structure

Carbon Energy, EarlyView.
The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Analysis of Thermal Sensitivity by High Voltage Insulator Materials

IEEE Access, 2020
Insulators serve bi-fold objectives of holding the conductor and electrical segregation from the grounded structure. For reliable operation of utility, electrical and mechanical strength of insulators are equally significant.

Development and validation of a deep survival model to predict time to seizure from routine electroencephalography

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to develop and validate a deep survival model (EEGSurvNet) that analyzes routine electroencephalography (EEG) to predict individual seizure risk over time, comparing its performance to traditional clinical predictors such as interictal epileptiform discharges (IEDs).

On the estimation of lightning peak currents from measured fields using lightning location systems [PDF]

Journal of Electrostatics, 2004
Although, due to the high variability of key parameters such as the return-stroke speed, it is impossible to determine the lightning current accurately from the remotely measured electric or magnetic field for a given event, we show in this paper that, for an assumed return-stroke model, the statistical estimation (e.g.

Clock gene dysregulation in epilepsy: A systematic review

Epilepsia Open, EarlyView.
Abstract Objective Epileptic seizures show a rhythmic pattern, being more frequent at particular times of the day (e.g., only occurring during sleep), suggesting a role of the circadian rhythm. Clock genes regulate the circadian rhythm and might be involved in the pathophysiology of epilepsy.

Time‐Domain Geoelectrical Modeling and Experimental Validation of Ground Potential Rise in Multilayer Soil Structures during Fault Events

Energy Science &Engineering, EarlyView.
This study develops a time‐domain geoelectrical model of ground potential rise (GPR) in multilayer soil that couples electromagnetic field theory with nonlinear fault arc resistance. Finite‐element simulations calibrated against scaled fault‐injection experiments reproduce measured GPR and step/touch voltages within 4.7% error, revealing that steady ...
