Trailing Edge Noise Reduction by Passive and Active Flow Controls [PDF]
, 2014 This paper presents the results on the use of porous metal foams (passive control) and dielectric barrier surface plasma actuations (active control) for the reduction of vortex shedding tonal noises from the nonflat plate type trailing edge serration in ...

Health Care Science, EarlyView.Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by persistent difficulties in social communication, social interaction, and repetitive behaviors. Early diagnosis is often hindered by subjective clinical assessments and limited data availability.

EHR‐Integrated Synoptic Operative Reporting for Head and Neck Oncologic Surgery
The Laryngoscope, EarlyView.EHR‐integrated synoptic operative templates for head and neck oncologic surgery was developed and implemented at a tertiary academic cancer center. Departmental adherence rose from 49% to nearly 80% over 6 months, and 94.5% of reviewed cases met targets for complete, internally consistent documentation. The resulting structured data dictionary provides

Computation of Trailing Edge Noise with a Discontinuous Galerkin Method [PDF]
, 2010 Trailing edge noise of a semi-infinite, thin, flat plate situated in low Mach number flow is computed in two spatial dimensions. The Acoustic Perturbation Equations (APE), which are employed as governing equations, are discretized via a Discontinuous ...

Experimental and numerical investigation of leading edge Krueger flaps at low Reynolds numbers [PDF]
, 2012 Recent publications examining the flight of Eagles have shown that leading edge feather deflections occur on the lower surface of the wings in free flight to create a leading edge flap analogous to a Krueger flap system.

Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

An experimental study of airfoil instability tonal noise with trailing edge serrations [PDF]
, 2013 This paper presents an experimental study of the effect of trailing edge serrations on airfoil instability noise. Detailed aeroacoustic measurements are presented of the noise radiated by an NACA-0012 airfoil with trailing edge serrations in a low to ...
