Abstract: Modern computer predictions of the frequency spectrum of net thrust for a rotor in turbulent flow display a number of features that call for interpretation. The success of the asymptotic ...

Abstract: One of the more intriguing features observed in rigorously computed frequency spectra of the random thrust on a turbulence-ingesting rotor is a shift of the broad peaks, or “haystacks,” to ...

Abstract: This paper establishes the concept of manufacturing risk assessment based on design features. It also presents a methodology for assessing risks associated with producing feature-rich products ...

Abstract: A 12-in. disk refiner was modified and instrumented. The resulting refining system had the capabilities to control the plate gap separation and at the same time monitor the refining or output ...

Abstract: This paper presents a critical analysis of the metric of rigid body displacements obtained from the so-called kinematic mapping. It is shown that this metric is not suitable for finite rigid ...

Abstract: An accurate estimation of displacement demand is essential to predict structural performance. However, the calculated displacements will vary depending on the analysis procedure. This paper shows the differences between ...

Abstract: This paper develops theoretical models to predict the radiation of low-frequency and impulsive sound from horizontal-axis wind turbines due to three sources: (i) steady blade loads, (ii) unsteady ...

Abstract: This paper presents the results of a research project aimed at examining the capabilities and challenges of two distinct but not mutually exclusive approaches to in-service bridge assessment: visual inspection and installed ...
