Simulation and Analysis of Protection of Electrical Networks against Lightning Strikes Using ATP/EMTP and MATLAB/SIMULINK

Algerian Journal of Signals and Systems
The objective of my work is the simulation and analysis of the protection of electrical networks against lightning strikes. To achieve this goal, I will use the simulation programs ATP/EMTP and MATLAB/SIMULINK to simulate a lightning strike in two cases:

Thermal behaviour analysis in a porcelain-housed ZnO surge arrester by computer simulations and thermography

High Voltage, 2019
In this article, an analysis of heat transfer in a porcelain-housed ZnO surge arrester is presented. Due to the fact that ZnO-based surge arresters are key components for protection and reliability of electrical systems, it is necessary to seek ...

Intrasplenic Thymus Organogenesis from Injectable Tissue Fragments Restores Functional T‐Cell Immunity

Advanced Science, EarlyView.
Clinical intramuscular thymus transplantation yields only short‐lived efficacy and marginal therapeutic benefits. Benefiting from the spleen's intrinsic strengths—rapid vascular perfusion, abundant developmental factors, and resident progenitors—the intrasplenic thymic grafts achieve robust thymic regeneration and substantial T‐cell reconstitution ...

Heteroatom‐Mediated Covalent Organic Framework Membranes With Nitrogen‐Enriched Nanochannels for Efficient Desalination

Advanced Science, EarlyView.
Heteroatom precursor engineering serves as a molecular‐level strategy to tailor hydrazide monomer reactivity and diffusion kinetics, enabling controlled assembly of highly crystalline COF membranes with ultramicroporous channels. The nitrogen‐enriched nanochannels deliver high water/ion selectivity via simultaneous water transport acceleration and ion ...

Phase Separation of SF3B1 Serves as a Critical Post‐Transcriptional Regulator During Early Mouse Embryogenesis

Advanced Science, EarlyView.
Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

On the Mitigation Effect of Surge Arresters on the Lightning Performance of Overhead Distribution Lines

, 2008
For the accurate statistical assessment of the lightning performance of distribution lines one needs to take into account the presence of protection devices such as surge arresters and shielding wire/neutral groundings.

Tumor Mechanical Remodeling via Bidirectional Calcium Redistribution Enables Deep Photothermal‐Immunotherapy

Advanced Science, EarlyView.
A bidirectional calcium‑redistributing nanomodulator rewires intra‑extracellular calcium homeostasis to remodel tumor mechanical microenvironments. It softens tumor stroma to facilitate deep tissue penetration while stiffening tumor cells, evoking amplified immunogenic cell death and robust CTL infiltration, which achieves potent deep photothermal ...
