Advanced Automated Crash Notification (AACN) algorithms use telemetric data from vehicles to notify emergency services of a collision involving the vehicle. The aim is to quickly dispatch the appropriate medical response to the crash scene. An important part of AACN systems is predicting occupant injury, which is highly dependent on the side of the vehicle that is struck in a crash. A given fro...

classical trajectory (monte carlo) calculation is used to calculate collision rate constants of ion-quadrupolar molecule interactions for the h¯+c2h2 system. the method presented here takes into account the effect of the induced dipole-induced dipole potential on ion-quadrupolar molecule collision rate constants. it is also assumed that the colliding particles have a definite size. the thermal ...

this paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. axial bearing analysis is done numerically using nonlinear finite element code ls-dyna. in this analysis, changes of two main parameters including measure of energy absorption o...

Iron is a ubiquitous constituent of cytochromes, oxygen-binding molecules and a variety of enzymes because of its property to transition from ferric (Fe3+) to ferrous (Fe2+) state, leading to change in the redox potential. However, the same property accounts for free radical injury. In order to overcome harmful effects of iron we investigated the possible protective effect of quercetin (QCT), a...

Luckily, not many storms are as destructive as Katrina. Since 1990, only Hurricane Andrew approaches it in the value of property damage, which was less than half that of Katrina in 2005 dollars. The attacks of September 11, 2001, did a comparable amount of property damage, but cost far more lives. That such catastrophes are extremely rare does not necessarily mean another will not occur in the ...

in this research, the effect of bubble surface area flux, sb, and particle size on flotation rate constant, k, of pyrite (fes2) particles was studied using bubble-particle interactions. the bubble-particle collision, attachment and detachment efficiencies were calculated under different flow regimes. the k increased with increase in the collision efficiency and decrease in the detachment effici...

The tackle is a physical contest between opposing players contending for territory and ball possession. During an 80 minute rugby union match, a player will physically engage in the tackle contest, whether as a ball-carrier or tackler, between 10 to 35 times depending on the position of the player (Deutsch et al., 2007; Quarrie and Hopkins, 2008). During a match, tight forwards (position number...

The intention of this research project was to calculate the e/π ratio for the proposed Shashlik Detector for the Compact Muon Solenoid Experiment by simulating proton collision events in a virtual detector. The e/π ratio is the ratio of the Shashlik’s ability to measure the energy of electromagnetic to hadronic particles. An upgrade is required for the electromagnetic calorimeter due to radiati...

The objective of this paper is to establish relationships between rainfall extremes and damage data from Dutch insurance industry. Rainfall data are based on a network of 33 automatic rain gauges held by the Royal Netherlands Meteorological Institute. Rainfall characteristics, such as peak rainfall intensity and rainfall volume, are correlated with damage statistics of claims in the vicinity of...

The CMS pixel detector is the innermost component of the CMS tracker occupying the region around the centre of CMS, where the LHC beams are crossed, between 4.3 cm and 30 cm in radius and 46.5 cm along the beam axis. It operates in a high-occupancy and high-radiation environment created by particle collisions. Studies of radiation damage effects to the sensors were performed throughout the firs...
