Decision theory process for making a mitigation decision on harmonic resonance in power systems
… power system, that has the potential for harmonic resonance. How to make a decision as to whether or not mitigation is needed is also researched. The two-stage decision theory process, developed by management scientists, to assist decision makers on making a decision when uncertainty, risk …

On self-annihilation: bending the borrowed light
… though pragmatic, backbone: the idea of Harmonic Resonance, or a musical outlook of the world that acknowledges the pivotal role of light and sound. With our technological progress and the frightening amount of information now available, the world continues to become exceedingly complex, …

Nonlinear resonance of trapped waves on a plane beach
… explanation of the nonlinear mechanism of sub-harmonic resonance. This type of theory has been extended by Minzoni & Whitham (1977), Rockliff (1978), and Rockliff & Smith (1985), among others. Rockliff also initiated a. theory whereby subharmonic resonance can be achieved by an incident wave of …

Nonlinear effects on interfacial wave growth into slug flow
… nonlinear evolution and the effects of wave resonances on the interface remain a subject of interest and will be the focus of this study. The Kelvin-Helmholtz (KH) instability is the traditional model for predicting interfacial instability in stratified flows. This linear instability occurs …

Stability design criteria and volt var control for distribution system with single phase solid state transformers
… certain circumstances, instabilities due to harmonic resonance are observed. A design criterion for solid state transformer during no load conditions has been proposed in order to avoid instability using an impedance-based analysis. Stability assessment is also extended to include the impact …

Experimental study of plasma transport using X-ray imaging spectroscopy in Alcator C-Mod
… hybrid layer is close to the Ar16+ 2nd harmonic resonant layer. This suggests that the pumpout of argon could be due to the energy absorbed from the enhanced left-hand polarized electric field through 2nd harmonic resonance. Further experiments are proposed to verify this impurity-wave …

Effects of Inlet Guide Vane Flow Control on Forced Response of a Transonic Fan
… which included one fundamental and multiple harmonic resonance crossings. Sensitivity of resonant response amplitude to full-span TEB flowrate, as well as optimal TEB flowrates, are documented for multiple modes. Resonant response sensitivity was generally characterized by a robust region of …

Miniaturised bandpass filters for wireless communications
… relatively wide stopband as the lowest spurious harmonic resonance is observed at thrice the fundamental frequency. Properties of this resonator, such as these and more are explored in depth to arrive at an accurate electrical equivalent circuit, which is used as the basis for high order filter …

Subsynchronous Resonance in Wind Farms
… transmission lines may cause subsynchronous resonance (SSR) in turbine-generators, which can lead to electrical instability at subsynchronous frequencies and potential turbine-generator shaft failures. This thesis deals primarily with the potential of subsynchronous resonance in induction …
