Formulation and experimental validation of a frequency transfer function of a rotor system with both an open crack and anisotropic support stiffness

open access: yesNihon Kikai Gakkai ronbunshu, 2018
This paper proposes a transfer function of rotating shaft system considering both an open crack and anisotropy in bearing support stiffness, which are both fundamental characteristics often observed in the rotating machinery.

Optical transfer function expansion of quadratic pupils

open access: yes, 2017
Quadratic pupils representing Gaussian apodization and defocus are expanded into Zernike polynomials. Combinations of the pupil expansion coefficients are used, in turn to expand the Optical Transfer Function into a novel set of basis functions.This item

Evidence‐Informed Multidisciplinary Consensus Guidance for the Psychosocial Care of Adolescents With High‐Risk Cancer: Recommendations From the Italian Association of Pediatric Hematology and Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with high‐risk cancer face complex developmental, psychosocial, and ethical challenges that extend beyond disease‐directed treatment. Although international recommendations exist for communication, psychosocial care, pediatric palliative care, survivorship, and shared decision‐making, these have largely evolved within ...

Testing the stability of the benefit transfer function for discrete choice contingent valuation data [PDF]

open access: yes, 2007
We examine the stability of the benefit transfer function across 42 recreational forests in the British Isles. A working definition of reliable function transfer is put forward, and a suitable statistical test is provided.

Resonance frequency control using the rank-one perturbation of the self-compliance matrix at interface degrees of freedom

open access: yesNihon Kikai Gakkai ronbunshu, 2019
A design method of a strongly coupled vibration system is required for improving noise and vibration performance of machinery. One of the authors proposed that analysis of the self-compliance matrix at interface degrees of freedom between two systems ...
