Influence of DVR on Adjacent Load and Its Compensation Strategy Design Based on Externality Theory

open access: yesEnergies, 2019
Dynamic voltage restorer (DVR) is a compensation device that can effectively improve power quality, and it is widely used to compensate the voltage sag on sensitive loads.

A New Approach to Improve PV Power Injection in LV Electrical Systems Using DVR

open access: yesIEEE Systems Journal, 2018
With increasing photovoltaic (PV) penetration in low-voltage (LV) distribution networks, voltage violation during the peak PV generation period is one of the main power quality concerns.

Optimal Control of Quantum Measurement

open access: yes, 2014
Pulses to steer the time evolution of quantum systems can be designed with optimal control theory. In most cases it is the coherent processes that can be controlled and one optimizes the time evolution towards a target unitary process, sometimes also in ...

Breakup of the aligned H$_2$ molecule by xuv laser pulses: A time-dependent treatment in prolate spheroidal coordinates

open access: yes, 2011
We have carried out calculations of the triple-differential cross section for one-photon double ionization of molecular hydrogen for a central photon energy of $75$~eV, using a fully {\it ab initio}, nonperturbative approach to solve the time-dependent ...

Relationship between Personality Characteristics and Accident Proneness of Iranian Bus Drivers

open access: yesSalāmat-i kār-i Īrān, 2018
Background and aims: Thousands of people die in road crashes each year and several hundred thousand are disabled, as a result of road traffic accidents. Counts of fatal accidents were caused by drivers who are not comply with their jobs.

Improved Fault Ride Through Capability in DFIG Based Wind Turbines Using Dynamic Voltage Restorer With Combined Feed-Forward and Feed-Back Control

open access: yesIEEE Access, 2017
This paper investigates the fault ride through (FRT) capability improvement of a doubly fed induction generator (DFIG)-based wind turbine using a dynamic voltage restorer (DVR). Series compensation of terminal voltage during fault conditions using DVR is

Strong coupling theory for driven tunneling and vibrational relaxation

open access: yes, 2000
We investigate on a unified basis tunneling and vibrational relaxation in driven dissipative multistable systems described by their N lowest lying unperturbed levels. By use of the discrete variable representation we derive a set of coupled non-Markovian

Rs DVR: перенос DVR в облачную среду

open access: yesT-Comm - Телекоммуникации и Транспорт, 2012
Операторы кабельного телевидения уже некоторое время предлагают в цифровых ресиве рах (STB) функционал цифровой видеозаписи (DVR), а потребители за последние пять лет быстро привыкли к этой технологии, которая позволяет сдвигать время просмотра и пользоваться другими расширенными возможностями, как например функциями паузы и немедленного повтора.

Avian neuronal morphology reveals pallial adaptations in Pigeons (Columba livia)

open access: yesAvian Research
Avian cognitive abilities rival those of primates. These capacities have been linked to high pallial neuronal density and prefrontal cortex-like dorsal ventricular ridge (DVR) circuitry.
