Electrochemical-Informed Equivalent-Circuit Thermal Framework for Smartphone Battery Drain: Mechanism Analysis, TTE Prediction, and Power-Saving Strategies

Batteries
Smartphone battery drain is governed by coupled effects of workload, electrochemical aging, and thermal feedback. Nonlinear behaviors such as voltage collapse remain challenging for traditional models.

Heat-pump performance: voltage dip/sag, under-voltage and over-voltage

The Journal of Engineering, 2014
Reverse cycle air-source heat-pumps are an increasingly significant load in New Zealand and in many other countries. This has raised concern over the impact wide-spread use of heat-pumps may have on the grid. The characteristics of the loads connected to

Distributed Monitoring of Voltage Collapse Sensitivity Indices

IEEE Transactions on Smart Grid, 2016
The assessment of voltage stability margins is a promising direction for wide-area monitoring systems. Accurate monitoring architectures for long-term voltage instability are typically centralized and lack scalability, while completely decentralized approaches relying on local measurements tend towards inaccuracy.

GECM-Based Voltage Stability Assessment Using Wide-Area Synchrophasors

Energies, 2017
Voltage instability is a crucial issue in the secure operation of power grids. Several methods for voltage stability assessment were presented. Some of them are highly computationally intensive, while others are reported not to work properly under all ...

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.
