Active control of coaxial jet flames under different fuel compositions through manipulation of mixing process with miniature jet actuators

Journal of Thermal Science and Technology, 2020
The gaseous fuel-air coaxial jet flow and combustion under different fuel compositions are actively controlled through periodic excitation of the initial jet shear layer with arrayed miniature jet actuators equipped on the inner surface of the annular ...

Active Pressure Ripple Control in Axial Piston Pumps through High-Frequency Swash Plate Oscillations—A Theoretical Analysis

Energies, 2019
Pressure ripple has always been a major drawback in hydraulic circuits, since it is the main source of the overall noise emitted by the pump. This article presents a theoretical analysis on the active control of the pressure ripple in an axial piston ...

Enhance of Energy Harvesting from Transverse Galloping by Actively Rotating the Galloping Body

Energies, 2019
Kinematic rotary control is here proposed conceptually to enhance energy harvesting from Transverse Galloping. The effect of actively orientating the galloping body with respect to the incident flow, by imposing externally a rotation of the body ...

Homeostatic Control of Neuronal Activity

, 2023
For healthy brain functioning, it is crucial that neuronal networks do not become hyperactive, but also, that they remain excitable. Homeostatic mechanisms ensure that neuronal activity remains within a functional range. How does that work? In this chapter, we will explore homeostatic control of neuronal activity.

The Effect of Proportional, Proportional-Integral, and Proportional-Integral-Derivative Controllers on Improving the Performance of Torsional Vibrations on a Dynamical System

Computation
The primary goal of this research is to lessen the high vibration that the model causes by using an appropriate vibration control. Thus, we begin by implementing various controller types to investigate their impact on the system’s reaction and evaluate ...
