Rotational motion of the head as a mechanism for brain injury was proposed back in the 1940s. Since then a multitude of research studies by various institutions were conducted to confirm/reject this hypothesis. Most of the studies were conducted on animals and concluded that rotational kinematics experienced by the animal's head may cause axonal(More)
The purpose of this study was to determine the force-time and force-displacement response of the human mandible under direct loading at the chin. Sub-fracture response of the mandible and temporomandibular joint (TMJ) were analyzed from 10 cadavers that were impacted at the chin with a 2.8-kg mass at drop heights of 300, 400 and 500 mm and a 5.2-kg mass at(More)
ion is a fundamental concept in software engineering. In this paper, we describe a class of abstractions that can simplify the construction of concurrent software, we call them coordination abstractions. Coordination abstractions capture communication, synchronization and topological information about concurrent computations. In the same way that a data(More)
The motion of the face carries great importance in research about speech production and perception. The suitability of a novel UV-based video recording system to track small facial motions during speech is examined. Tests are performed to determine the calibration and system errors, as well as the spatial and temporal resolutions of the setup. Results of(More)
While numerous studies have been conducted to determine side impact responses of Post Mortem Human Surrogates (PMHS) using sled and other equipment, experiments using the biological surrogate in modern full-scale vehicles are not available. The present study investigated the presence of oblique loading in moving deformable barrier and pole tests. Threepoint(More)
