OBJECTIVE Determine the effects of BMI on the risk of serious-to-fatal injury (Abbreviated Injury Scale ≥ 3 or AIS 3+) to different body regions for adults in frontal, nearside, farside, and rollover crashes. DESIGN AND METHODS Multivariate logistic regression analysis was applied to a probability sample of adult occupants involved in crashes generated by combining the National Automotive Sam...
In this study, head injury criteria (HIC) and chest severity index (CSI) assessments are made based on finite element simulation. Simulations are carried out through nonlinear finite element analysis software LS-Dyna. The effect on the occupant’s injury of introducing aluminum alloy, AA5182, to automotive side members is highlighted in comparison to the existing model made of steel. The HIC and...
Hemodynamic activity in occipital, temporal, and parietal cortical areas were recently shown to correlate across subjects during viewing of a 30-minute movie clip. However, most of the frontal cortex lacked between-subject correlations. Here we presented 12 healthy naïve volunteers with the first 72 minutes of a movie ("Crash", 2005, Lions Gate Films) outside of the fMRI scanner to involve the ...
The UK Co-operative Crash Injury Study currently includes data on 205 seat belted drivers from frontal impacts in which an air bag deployed; of these, 142 suffered some degree of injury. To detect the influence of frontal air bags, the distribution of injury over the body regions of these drivers was compared to that of a much larger group from vehicles without air bags. The injured drivers fro...
Abstract: In this paper, new front-end structures (smart) are proposed to improve vehicle frontal impact. The work carried out in this paper includes developing and analysing mathematical models of vehicle-to-rigid barrier offset frontal impact using fixed and extendable smart front-end structures with piecewise linear characteristics. In these models, vehicle components are modelled by lumped ...
توزیع های چند متغیره، نقش مهمی در تئوری آمار وکاربردهای آن داشته است، بنابر این همواره مورد توجه محققان و دانشمندان علوم مربوطه بوده. نکته ی مهمی که بیشتر پژوهشهای محققان را به خود اختصاص داده، بدست آوردن و یا بررسی توزیع های چند متغیره بوسیله ی توزیع های حاشیه ای آنهاست. می دانیم که با داشتن توزیع مشترک، دستیابی به توزیع های حاشیه ای چندان مشکل نیست. اما در مورد ساختن توزیع مشترک و بررسی ویژگ...
advanced driver assistance systems (adas) have the potential to accomplish a major contribution to road safety. this is valid for minor crashes to very severe accidents with personal injuries. the allianz centre for technology attends the development of new driver assistance systems by carrying out accident analysis and estimating the efficiency of new adas. in this context new adas from differ...
A detailed examination was undertaken of hospitalized car occupants who sustained a lower limb injury in a frontal crash. The assessment included an analysis of the type, severity and causes of these injuries and mechanisms involved in lower limb fractures. The findings showed that fractures and dislocations occurred in 88% of lower limb injury cases, that more than half were from crashes < 48 ...
Recent research revealed that greater proportion of heavier male occupants and lighter female occupants sustain serious injuries in frontal crash. The cause is thought that the frontal occupant restraint systems are designed to minimize the injury risk for 50 h percentile occupant only, and its characteristics are not adjustable. In this study, vent hole area of the airbag and load limiter forc...
Stock price crash risk has a significant impact on investors, creditors, managers, and shareholders, so the prediction of this phenomenon is a very important issue in investment and risk management decisions. This research investigates the effect of business strategy and stock price synchronicity on stock price crash risk. Following Bentley et al.[2], composite strategy score has been used to ...
