Sentence examples for boundary irregularity from inspiring English sources

The eigenmodes are calculated numerically on various examples, and it is shown first that, whatever the shape and characteristic sizes of the boundary, irregularity always induces an increase of localized eigenmodes and a global decrease of the existence surface of the eigenmodes.

The Solidity feature is a measure of nucleus shape convexity, it is calculated by the ratio of the nucleus area over the area of the smallest convex hull polygon that can contain the nucleus, it indicates nucleus outline uniformity and it decreases with increasing nuclei boundary irregularity.

Sometimes part of the transmitted wave travels to the receiver by reflection off a smooth boundary whose edge irregularities are only a fraction of the transmitted wavelength.

In particular, the effects of element geometry such as aspect ratio, skewness, shape of distortion, curved boundary and irregularity of mesh are illustrated.

In addition, the strength drop noticeable with small specimens which was obtained in the experiments is explained by the presence of a weak surface layer of constant thickness (caused e.g., by drying, surface damage, aggregate size limitation at the boundary, or other irregularities).

Superimposed Swarm Ne values can be used to partially restore boundaries of the irregularity oval.

Additionally, the model is extended to incorporate the capability to model transition due to surface irregularities in the form of backward-facing steps with maximum non-dimensional step sizes of approximately 1.5 times the local displacement thickness of the boundary layer where the irregularity is located (i.e k/δ∗⪅1.5) at upstream turbulence intensities in the range 0.01

An experimental investigation of wall pressure fluctuations generated by turbulent boundary layers over surface irregularities has been conducted in a backward forward-facing step geometry simulating a large aspect-ratio cavity.

The impurity effective-mass Schrödinger equation was reduced to a one-dimensional equation with an effective potential containing both the Coulomb interaction and the effects of the wire surface irregularities through the boundary conditions.

This mathematical feature accounts for the irregularity of the damage boundary that can act as a stress concentration factor, thus causing mechanical strength reduction.

While the Dirichlet condition treatment leads to second-order accuracy for the temperature field, it only gives a first-order accurate boundary heat flux because of the irregularity of the cuts by the curved boundary with the lattices.
