Dynamic Observation of Lacy Pattern Formation in a Bone Tissue Model Using Liquid Phase Scanning Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Here, we establish a low‐dose liquid‐phase electron microscopy workflow for real‐time observation of biological processes in hydrated conditions. Beam damage is reduced by imaging only 20% of the pixels and reconstructing the complete image using an inpainting algorithm.

OPTIMAL CONTROL OF VOLTAGE AND REACTIVE POWER OF POWER SYSTEM

IFAC Proceedings Volumes, 1987
Abstract In this paper, from the view point of economy and security of a power system, a synthetic mathematical model is presented for minimizing system losses and improving voltage level. At the same time, it is taken into account that when the reactive power is insufficient or it is hard to operate the system normally, the system will be supplied ...

Social Cognitive Optimization Algorithm with Reactive Power Optimization of Power System

2010 International Conference on Computational Aspects of Social Networks, 2010
A reactive power optimization is a multi-modal, mixed-variable, multi-constraint and nonlinear planning problem. In the last decades, many computational intelligence-based techniques have been proposed for reactive power optimization problem, such as genetic algorithm (GA), particle swarm optimization (PSO), differential evolution (DE), Tabu search ...
