A Novel Enhanced Active Power Control Maximum Power Point Tracking Algorithm for Photovoltaic Grid Tied Systems

open access: yesAdvances in Electrical and Computer Engineering, 2021
The PV systems connected to the grid will be a very significant renewable energy source in the power systems. Numerous researchers believe that in approaching years major amount of energy on the planet will be produced by Photovoltaic grid tied systems.

Distributed control of reactive power flow in a radial distribution circuit with high photovoltaic penetration

open access: yes, 2009
We show how distributed control of reactive power can serve to regulate voltage and minimize resistive losses in a distribution circuit that includes a significant level of photovoltaic (PV) generation.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Reliability analysis of single-phase photovoltaic inverters with reactive power support [PDF]

open access: yes, 2010
Reactive power support is expected to be an emerging ancillary requirement for single-phase photovoltaic (PV) inverters. This work assesses related reliability issues and focuses on the second stage or inversion process in PV inverters. Three PV inverter

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein

open access: yesFEBS Open Bio, EarlyView.
Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

Parameter Optimisation of a Virtual Synchronous Machine in a Microgrid

open access: yes, 2016
Parameters of a virtual synchronous machine in a small microgrid are optimised. The dynamical behaviour of the system is simulated after a perturbation, where the system needs to return to its steady state.

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

open access: yesFEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

The Influence of Measurement Methodology on the Accuracy of Electrical Waveform Distortion Analysis

open access: yesMeasurement Science Review, 2018
The present paper covers a review of documents that specify measurement methods of voltage waveform distortion. It also presents measurement stages of waveform components that are uncommon in the classic fundamentals of electrotechnics and signal theory,
