Evidence for nonlinear reflections in shock-containing noise near high-performance military aircraft

Autor: Aaron B. Vaughn, J. Micah Downing, Kevin M. Leete, Bradley R. Adams, Kent L. Gee

Publikováno v: The Journal of the Acoustical Society of America. 149:2403-2414

Skewness values for the pressure time derivative are greater at ground-based measurements near a tactical aircraft than they are at nearby off-ground locations. A possible explanation for this phenomenon is the occurrence of nonlinear, irregular shoc

A common approach in the literature when obtaining surrogate models of reflectarray unit cells is to include, among other variables, the angles of incidence as input variables to the model. In this work, we use support vector regression (SVR) to comp

Computational study of effectiveness of winglet at subsonic speed

Autor: M. Sundararaj, V. Giridharan, N. Elumalai, K. S. Mahesh Kumar

Publikováno v: AIP Conference Proceedings.

A winglet is a device attached at the wingtip to reduce the strength of tip vortex, which is used to improve aircraft efficiency by reducing induced drag. The arrangement of winglet is a vertical or angled extension at the tips of each wing. Winglets

Three-dimensional response of steel moment-resisting buildings under seismic sequences

Autor: Jorge Ruiz-García, Saman Yaghmaei-Sabegh, Edén Bojórquez

Publikováno v: Engineering Structures. 175:399-414

This study examines the response of three-dimensional (3-D) steel moment-resisting buildings having 3-, 9-, and 20-story height under bi-directional attack of real seismic sequences with different earthquake ground motion features. For this purpose,

Impact Response of Thin Aluminium Plate with Varying Projectile Obliquity and Span Diameter

Autor: Mohd. Ashraf Iqbal, Pramod Kumar Gupta, Gaurav Tiwari

Publikováno v: Iranian Journal of Science and Technology, Transactions of Mechanical Engineering. 44:93-102

This paper presents a three-dimensional (3-D) numerical investigation to know the effect of projectile obliquity and target span diameter on ballistic performance of 1-mm-thick target plate against ogive nosed projectile. The span diameter of 1100-H1

Association of Body Mass Index With Severity and Lesion Location in Adolescents With Osteochondritis Dissecans of the Knee

Autor: Tymoteusz J. Kajstura, R. Jay Lee, Walter Klyce, Davis Rogers

Publikováno v: Orthopaedic Journal of Sports Medicine. 9:232596712110453

Background: The association between body mass index (BMI) and severity of osteochondritis dissecans (OCD) of the knee at presentation is poorly understood. Hypothesis: We hypothesized that adolescents in higher BMI percentiles for age and sex would h

Free vibration numerical simulation technique for extracting flutter derivatives of bridge decks

Autor: Fuyou Xu, Zhanbiao Zhang

Publikováno v: Journal of Wind Engineering and Industrial Aerodynamics. 170:226-237

A numerical simulation technique based on computational fluid dynamics (CFD) for determining the time-varying histories of free vibration displacements, velocities, and aerodynamic forces of bridge decks is presented. The weak coupling method is used

Proposal for peruvian standard considering the effect of bidirectionality and the angle of incidence of an earthquake

Autor: Edisson Moscoso, Luis G. Quiroz

Publikováno v: TECNIA. 29

Currently, it is considered that seismic actions act independently in two or three main directions orthogonal to each other, applying them to the building, without this necessarily being valid. It is for such, that seismic analysis of buildings shoul
