Sentence examples for modes with negative from inspiring English sources

If damping is neglected, the procedure is quite similar to that usually followed for a non-rotating structure, the only difference being the possibility of obtaining also modes with negative modal masses which cannot in general be neglected.

At low pressure, it corresponds to the Alfvén mode with negative frequency, ω = −k∥υ A. Physically, it means that the azimuthal phase speed of this wave is directed opposite to the diamagnetic drift velocity of ions.

The growth of instability depends on the frequency and wavenumber detunings between these longitudinal waves one of them is a slow beam mode with negative or zero wave energy defined near the linear stability boundary.

The authors' research group (2012) proposed an oscillation source locating method that could directly locate the oscillation source in the governors or exciters of generators when there is an FO [19, 20, 21] (This method can also be used to distinguish the governors or exciters that participate in a local mode with negative damping).

Measurements were performed in the chemical ionisation mode with negative ions using ammonia as reagent gas.

MALDI-TOF-MS/MS spectra were acquired in LIFT mode with negative polarity and a mass isolation window of 0.8% of the parent mass.

Fracture load is experimentally measured for round-tip V-notched Brazilian disk (RV-BD) specimen made of PMMA and loaded under mixed mode І/ІІ with negative mode І components.

The modes with a negative refractive index are often called back propagating waves since the propagation directions of their energy and their phase are opposite.

Aggression is related to cortical thickness in regions associated with the default mode network, with negative associations in boys and positive associations in girls.

It is shown by the finite element (FE) analysis that although the notch is under mixed mode І/ІІ loading with negative mode І conditions and the notch bisector line experiences compressive stresses, the notch round border is divided into two compressive and tensile sides, suggesting that two critical points may exist on the notch border.

It is hypothesized that a consortium's metabolic activity can also be described using linear combinations of the elementary modes (with non-negative coefficients).
