Sharp curved track corrugation: From corrugation observed on-site, to corrugation reproduced on simulators

Tribology International, 2009
For more than a century, rail corrugation has been a major issue for mass transit networks. Although studied mainly by global analyses of train/track dynamics, knowledge about why corrugation appears on some types of trackform in some circumstances and not in others remains inadequate.

Short pitch corrugation mitigation by rail constraint design

International Journal of Mechanical Sciences, 2023
Short pitch corrugation is a quasi-periodic rail defect that induces a high level of noise and accelerates track degradation. This paper proposes a methodology to mitigate short pitch corrugation by rail constraint design, including four steps. In Step 1,

Field measurement and model prediction of rail corrugation [PDF]

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2020
In a field test, three corrugation profiles of rails and their corresponding vibrations were measured, and the wavelengths and frequencies of rail corrugations were obtained.

Shielding effectiveness of corrugations in corrugated horns

IEEE Transactions on Antennas and Propagation, 1978
A moment-method solution is used to obtain new design data for corrugated horns. The current density on the walls of corrugated dihedral horns is evaluated as a function of such corrugation parameters as the tooth density, and the ratio of the gap to the period (of the corrugations).

Corrugated waveguide with helically continuous corrugations

IEEE Transactions on Antennas and Propagation, 1979
The cylindrical hybrid mode propagation and radiation characteristics have been theoretically analyzed, and corresponding experimental investigations have been carried out for a corrugated waveguide with helical anisotropy. Under the influence of helical corrugation the plane of polarization of the hybrid mode is found to rotate slowly as it moves ...

White corrugated mucosa

The Journal of the American Dental Association, 1988
A patient with white sponge nevus involving the buccal mucosa, labial mucosa, and soft palate is reported. The salient clinical and histological features of the disease were discussed. This diagnosis should be considered when bilateral white lesions of buccal mucosa are encountered.

Anatomy of the Corrugator Muscle

Journal of Craniofacial Surgery, 2017
The aim of this article is to systematically review the anatomy and action of the corrugator muscle. PubMed and Scopus were searched using the terms "corrugator" AND "anatomy." Among the 60 full texts from the 145 relevant abstracts, 34 articles without sufficient content were excluded and 4 articles drawn from the reference lists were added. Among the

Anatomy of the Corrugator Supercilii Muscle: Part I. Corrugator Topography

Plastic and Reconstructive Surgery, 2007
Complete corrugator supercilii muscle resection is important for the surgical treatment of migraine headaches and may help prevent postoperative abnormalities in surgical forehead rejuvenation. Specific topographic analysis of corrugator supercilii muscle dimensions and its detailed association with the supraorbital nerve branching patterns has not ...
