Aircraft braking maneuvers are safety-critical on-ground motions that exhibit complex dynamics and significant dependence on system operating conditions. The fundamental interface between the aircraft ground is landing gear. Among gear components, shock absorbers may be subject to gas leakage during their lifetime, which an anomaly could compromise lateral stability properties of regimes found ...
Near side impact crashes – especially pole impacts – have the potential to induce antero-lateral oblique loads to the chest. Current side impact dummies and most laboratory experimental studies have been designed to assess direct lateral impacts. A recent analysis of real world crashes indicated that the human chest experiences oblique loading in side impact crashes – in particular crashes into...
[1] To reexamine the potential for lateral mixing over large distances (>100 km) by impact craters, a mathematical model utilizing the stable probability distribution is proposed for estimating lateral mixing efficiency on the Moon. The proposed model divides material mixing into shallow slope and steep slope regimes. Mixing in the shallow slope regime conforms to the condition that the exponen...
BACKGROUND The purpose of this study was to describe the impact of partial lateral glossectomy on midsagittal tongue movement during speech. METHODS Using B-mode ultrasound, the midsagittal tongue movement of 10 patients with lateral partial glossectomy during a standardized reading passage was analyzed before and after surgery. Six normal adults served as control speakers. The main outcome m...
The lengths of the digital bones of the fore- and hind-limbs obtained post mortem from 40 cattle of different ages were measured using digital radiographs. The lengths of the individual digital bones and the overall length of the digit were determined using computer software. The lateral metacarpal/metatarsal condyle, and lateral P1 and P2 were significantly longer than their medial counterpart...
in the present research, in contrast to the available papers, not only the superelasticity but also the shape memory effects are taken into account in determination of the impact responses. at the same time, in addition to modifying brinson’s model for the shape memory alloys (smas), to include new parameters and loading events, and hertz contact law, distributions of the sma phases are conside...
introduction : lateral osteotomy is a major part of rhinoplasty for remodeling external facet of the nose and narrowing of nasal base and dorsum after removal of the hump with the edema and ecchymosis being the major sequels of the operation. the present study compared post-operative edema and ecchymosis and mucosa tears between internal and external osteotomy techniques. materials and methods ...
A numerical model of 84 high-strength concrete-filled square steel tubular columns (HSCFST) with local defects is developed using ABAQUS. The effects parameters such as crack angle, length, impact surface and energy on the resistance HSCFST are considered. results show that under effect corrosion, a horizontal cracks will phenomenon closure when subjected to front impact. force platform value m...
