Optimization of Control Source and Error Sensor Locations in Free Field Active Noise Control
<p>Previous work has shown that active noise control (ANC) can be applied to axial cooling fans. Optimization of the control source and error sensor placement is desired to maximize the attenuation using ANC. A genetic algorithm was developed to find the optimal placement of control sources for a …

Active Minimization of Acoustic Energy Density to Attenuate Radiated Noise from a Diesel Generator
The focus of this thesis was to use active noise control (ANC) to globally minimize the tonal and broadband noise radiating from a diesel generator enclosure. The major goal of this research was to show that minimizing the noise within the enclosure can lead to an overall sound pressure level (SPL) …

Analytical investigation of active control of radiated inlet noise from turbofan engines
… developed to study the potential of active noise control techniques for reducing radiated tonal inlet noise from turbofan engines. The analytical model consists of multiple control sources placed in the periphery of the engine inlet duct which inject anti-noise into the duct to destructively …

Active control of automobile cabin noise with conventional and advanced speakers
Recently much research has focused on the control of enclosed sound fields, particularly in automobiles. Both Active Noise Control (ANC) and Active Structural Acoustic Control (ASAC) techniques are being applied to problems stemming from power train noise and road noise (noise due to the …

Investigation of Multiphase Coupled Inductor Topologies for Point-of-Load Applications
… loop with the current in this loop as the control source. Compared with the conventional structure, the proposed structure can achieve a great output voltage spike reduction and output capacitance reduction. Third, although an ICL and an HCL are promising candidates for multiphase coupled …

Investigating the Effect of Attentional Control on Source Monitoring and DRM Memory Performance
… over gist-based processing. Studies examining source monitoring in DRM paradigms have highlighted the importance of attentional control (AC), with divided attention (DA) during encoding leading to impaired source detail recollection. This thesis examined how AC affected the accuracy of source …

Enabling reliable control with communication constraints
… safety, the communication networks that control these autonomous systems will face strict latency and reliability requirements. Wireless resources are fundamentally scarce, and this scarcity is further compounded by the need for high reliability and low latency. This motivates research …
