A simplified mathematical theory of MHD power generators

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
We present a simplified version of the Faraday magnetohydrodynamics (MHD) generators theory. The effect of the Loretz force against the fluid ow is neglected, whence it follows the uniform ow of the plasma. We use Lazăr Dragoș’s analytic solution for the

The Design and Optimization of a Novel Hybrid Excitation Generator for Vehicles

World Electric Vehicle Journal
Silicon rectifier generators, which are single-excitation generators, are commonly used in vehicles. However, a traditional single-excitation generator cannot satisfy the requirements of modern vehicles due to its low efficiency, high failure rate and ...

State Estimation-Based Hybrid-Triggered Controller Design for Synchronization of Repeated Scalar Nonlinear Complex Dynamical Networks

IEEE Access, 2023
The goal of this work is to examine the issue of state estimation-based synchronization of nonlinear complex dynamical networks that are prone to external disturbances, repeated scalar nonlinearities and time-varying coupling delays.

Electromagnetic characteristic of a novel hybrid excitation generator for vehicles based on the field-and-circuit method

Frontiers in Mechanical Engineering
IntroductionThe electro-magnetic generator commonly used in automobiles generally has high excitation loss leading to low efficiency. And it cannot effectively provide power for the vehicle, thus shortening battery life.In order to solve the issues, a ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
