Analytical study of the nonlinear behavior of a shape memory oscillator: Part II-resonance secondary
(Springer, 2010-06-01)
In Part II of this work, we investigated the dynamics of the shape memory oscillator, in the particular case of the secondary resonances. We used the equation of motion developed in Part I (Piccirillo et al., Nonlinear ...
Analytical study of the nonlinear behavior of a shape memory oscillator: Part I-primary resonance and free response at low temperatures
(Springer, 2010-03-01)
In this work, the response of a single-degree-of-freedom shape memory oscillator subjected to the excitation harmonic has been investigated. Equation of motion is formulated assuming a polynomial constitutive model to ...
On the undamped free vibration of a mass interacting with a Hertzian contact stiffness
(2011-12-01)
Three methods are used to determine the natural frequency of undamped free vibration of a mass interacting with a Hertzian contact stiffness. The exact value is determined using the first integral of motion. The harmonic ...
Understanding landscape-primary productivity and biodiversity relationship through graph metrics
(2020)
Besides landscape ecological studies, the traditional approach to trying to understand
ecological processes that occur in a landscape is the use of spatial statistics. However,
this does not take into account that many of ...
Multilevel cervical myelopathy treatment: open-door laminoplasty vs. multiple cervical arcocristectomies
(2014)
Purpose: Cervical myelopathy due to posterior multiple level compression remains a surgical challenger. Many surgical options have been used in the last years, but the best choice is unclear. We compared open-door laminoplasty ...
Greening at multiple scales promote biodiverse cities: A multi-scale assessment of drivers of Neotropical birds
(Elsevier GmbH, 2021)
© 2021 Elsevier GmbHBiodiversity-sensitive cities can contribute to reconnect humans with nature and halt global biodiversity loss. Achieving biodiversity-sensitive cities is challenging, especially in regions threatened ...
Fine-scale Beta-diversity Patterns Across Multiple Arthropod Taxa Over a Neotropical Latitudinal Gradient
(2015-09-01)
Documenting how diversity patterns vary at fine- and broad scales may help answer many questions in theoretical and applied ecology. However, studies tend to compare diversity patterns at the same scale and within the same ...
Anisotropy of the Taylor scale and the correlation scale in plasma sheet magnetic field fluctuations as a function of auroral electrojet activity
(American Geophysical Union, 2010-12)
Magnetic field data from the Cluster spacecraft in the magnetospheric plasma sheet are employed to determine the correlation scale and the magnetic Taylor microscale from simultaneous multiple‐point measurements for multiple ...
Self-reported urinary impairment identifies ‘fast progressors’ in terms of neuronal loss in multiple system atrophy
(Elsevier B.V., 2019)
© 2018 Elsevier B.V. Introduction: MSA is an adult-onset, sporadic, progressive parkinsonian syndrome characterised by the presence of akinesia, cerebellar dysfunction, autonomic failure and pyramidal signs. Annualized-whole-brain ...
