Novel Lightweight Noise and Vibration Control Treatments for Marine Structures
… magnitudes on the order of 15 dB at their tuning frequencies while providing overall vibration reduction of 5 dB or greater at higher frequencies. HG blankets were also capable of reducing plate resonance vibration up to 15 dB at their tuning frequencies and produced overall vibration …

An Investigation of the Feasibility of Microscale Adaptive Passive Vibration Neutralizers
… derived and compared to experimental results. A tuning algorithm is derived from a curve-fit of experimental tests on the specific neutralizer. A more generic tuning algorithm is also developed, which does not require testing of the neutralizer for optimal control. Both tuning algorithms are …

Vibration Energy Harvesting for the Development of autonomous monitoring Systems. Application to railway Bridges
… the study introduces a novel stochastic tuning strategy that accounts for uncertainties in bridge dynamics during train passages. By stochastic characterising harvested mechanical energy, the method identifies optimal tuning frequencies without requiring full experimental modal …

Phase Noise in CMOS Phase-Locked Loop Circuits
… synthesizer is proposed to increase its tuning range. The switchable PLL which integrates two phase-locked loops with different tuning frequencies are designed and fabricated in 0.5 µm CMOS process to analyze the effects under HCE and NBTI. A 3V 1.2 GHz programmable phase-locked loop …

Fundamental Studies In the Lamb-Wave Interaction Between Piezoelectric Wafer Active Sensor and Host Structure During Structural Health Monitoring
… order to achieve single mode excitation, i.e., tuning, a requirement for most of the SHM algorithms (time reversal, phase-array, and imaging).</p> <p>To achieve our research goal, we had to go beyond the current state of the art in modeling and understanding the load transfer from PWAS to the …
