Structure-Borne Vehicle Interior Noise Estimation Using Accelerometer Based Intelligent Tires in Passenger Vehicles
… and radial acceleration data. An Inertial Measurement Unit (IMU) and velocity box (VBOX) were instrumented in the vehicle to measure the acceleration at the center of gravity (COG) position of the vehicle and the longitudinal velocity of the vehicle respectively. The vehicle was also …

Laboratory measurements of the sound generated by breaking waves
… to be the dominant source of sea surface sound at frequencies greater than 500 Hz and the presence of breaking waves on the ocean surface has been shown to enhance the scattering of microwave radiation. Previous studies have shown that breaking waves can be detected by measuring the …

Experimental assessment of the internal flow behavior of supercritical carbon dioxide
… An innovative method to measure the speed of sound through the use of Helmholtz resonators was developed and investigated. Shock tube experiments and static high pressure air tests in the blowdown facility were conducted to determine the viscous damping in the resonators. The results indicate …

Measurement and analysis of breath sounds
Existing breath sound measurement systems and possible new methods have been critically investigated. The frequency response of each part of the measurement system has been studied. Emphasis has been placed on frequency response of acoustic sensors; especially, a method to study a diaphragm type …

Quantitative measurements of temperature using laser-induced thermal grating spectroscopy in reacting and non-reacting flows
… excitation of an absorbing species in the measurement region to produce a thermal grating, are acquired for systematic measurements of temperature in high pressure flames using OH and NO as target absorbing species in the burned gas. The signal obtained in LITGS measurements appears in the …

The Role of Ethical Evaluation of Corporate Social Responsibility in the Perception of Corporate Hypocrisy, the Intention of Opinioned Communication and Behavior toward a Firm
… CSR communication. First, this study found sound measurement reliability and validity of the proposed four-item scale of four dimensions in ethical CSR evaluation (i.e., self-interested motives, self-interested outcomes, altruistic motives and altruistic outcomes). Further, this study also …
