Operational Modal Analysis of Rotating Machinery [PDF]
, 2018 Harmonic excitation of structures caused by rotating equipment is a problem faced by many engineers in the field of Operational Modal Analysis (OMA). Several methods to discard the influence of harmonic inputs over systems natural responses has been proposed in the literature and implemented in various software solutions. This paper recalls some of the

Operational Modal Analysis of Offshore Wind Turbine Tower under Ambient Excitation
Journal of Marine Science and Engineering, 2022 The condition of an offshore wind turbine (OWT) should be monitored to assure its reliability against various environmental loads and affections. The modal parameters of the OWT can be used as an indicator of its condition. This paper combines the Kalman

ASSIST: Refinement of a Benefits Navigator Intervention Among Low‐Income Pediatric Oncology Families
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Children with cancer living in poverty experience worse survival and quality of life. Interventions connecting low‐income families to benefits (e.g., Supplemental Nutrition Assistance Program [SNAP] improve health outcomes; yet nearly 50% of SNAP‐eligible pediatric oncology families are unenrolled.

Understanding and managing identification uncertainty of close modes in operational modal analysis
Mechanical systems and signal processing, 2021 Close modes are much more difficult to identify than well-separated modes and their identification (ID) results often have significantly larger uncertainty or variability.

Improved Modal Assurance Criterion using a quantification of identification errors per mode/sensor [PDF]
, 2014 Scanning laser vibrometer measurements generate detailed maps of modal characteristics in normal or 3D directions. Since many points are measured, individual validation of cannot be performed manually in a reasonable time frame and a notable fraction of ...
