Modulational instability of Rossby and drift waves and generation of zonal jets [PDF]

, 2010
We study the modulational instability of geophysical Rossby and plasma drill waves within the Charney-Hasegawa-Mima (CH M) model both theoretically, using truncated (four-mode and three-mode) models, and numerically, using direct simulations of CHM ...

Triple cascade behaviour in QG and drift turbulence and generation of zonal jets [PDF]

, 2009
We study quasigeostrophic (QG) and plasma drift turbulence within the Charney-Hasegawa-Mima (CHM) model. We focus on the zonostrophy, an extra invariant in the CHM model, and on its role in the formation of zonal jets.

Adaptive-Output-Voltage-Regulation-Based Solution for the DC-Link Undervoltage of Grid-Forming Inverters

, 2023
This paper proposes an adaptive-output-voltage regulation (AOVR) based solution to alleviate the dc-link undervoltage for grid-forming (GFM) inverters.

Zonal-mean atmospheric dynamics of slowly-rotating terrestrial planets

, 2019
The zonal-mean atmospheric flow of an idealized terrestrial planet is analyzed using both numerical simulations and zonally symmetric theories, focusing largely on the limit of low planetary rotation rate.

Comparison of Effect Efficiency and Voltage Regulation Between Three-Phase Transformer Winding Connections

, 2020
A transformer is an important device in electrical processes, as we know static electricity that involves magnetically coupled coils to increase or decrease the voltage.

Voltage dip generator for testing wind turbines connected to electrical networks [PDF]

, 2011
This paper describes a new voltage dip generator that allows the shape of the time profile of the voltage generated to be configured. The use of this device as a tool to test the fault ride-through capability of wind turbines connected to the electricity

The structure of zonal jets in geostrophic turbulence [PDF]

, 2012
The structure of zonal jets arising in forced-dissipative, two-dimensional turbulent flow on the β-plane is investigated using high-resolution, long-time numerical integrations, with particular emphasis on the late-time distribution of potential ...

Correction of conductance measurements in non-space-clamped structures: 1. Voltage-gated K+ channels [PDF]

, 2003
To understand functions of a single neuron, such as propagation and generation of synaptic or action potentials, a detailed description of the kinetics and distribution of the underlying ionic conductances is essential.

Influence of bottom topography on integral constraints in zonal flows with parameterized potential vorticity fluxes [PDF]

, 2013
An integral constraint for eddy fluxes of potential vorticity (PV), corresponding to global momentum conservation, is applied to two-layer zonal quasi-geostrophic channel flow. This constraint must be satisfied for any type of parameterization of eddy PV
