Human Health Risk Assessment of Space Radiation

University of Pittsburgh-Ashmita Rajkumar
  • Technical Paper

To be published on 2020-03-10 by SAE International in United States
Mars has been the topic of colonization and discovery for the last few decades but there have been hindrances in implementing the mission. This focus on Mars colonization has only deepened after the discovery of water on its surface. The discovery of water on Mars has led researchers to believe that its sustainability of life is higher than any other uncolonized planet. Although, life can survive on Mars, it is highly unethical to send communities to Mars without acknowledging the risks, especially those concerning the well being of humans. The risks of living on Mars are slowly unraveling through extensive research, but it is evident that certain health care measures must be taken in order to prevent potentially fatal conditions. One of the biggest problems is health concerns that astronauts face after returning from Mars. Health problems in space have been increasingly difficult to deal with because of the lasting circumstances that astronauts suffer upon returning back to Earth. As a result of these issues, NASA has delayed its Mars mission to circa 2028. Another…

Published 2019-11-21 by SAE International in United States
Emergency calls made by in-vehicle systems in the event of a crash , serious incident or manually by a vehicle occupant assist in significantly reducing road deaths and injuries. But still there are more road accidents happen due to abnormality of driver and fatality rate tend to increase because of this. Drivers have a poor health issues, especially when they travel for long, they may get drowsiness and this leads to lack of concentration while driving and because of this concentration issue any serious issue can happen to the driver. This serious conditions can be totally unavoided. This invention provides the solution for contacting the people, who is known to victim very well. during emergency conditions. This may assist victim to get a immediate medical help.

  • 2019-28-2460
Published 2019-11-21 by SAE International in United States
Vehicular accidents are life-threatening and result in fatal casualties in developing country such as India. According to estimates, traffic accidents kill more people in India than diseases like Cancer and AIDS. More than 150,000 people are killed every year in traffic accidents in India, which works out to 400 fatalities a day, far higher than developed auto markets like the U.S., which had logged about 40,000 deaths in 2016. The World Health Organization estimates road accidents cost most countries about 3 per cent of their gross domestic product.India being the fastest growing economy will be the world’s third-largest car market after China and the U.S. by 2020, according to automobile researchers.According to research study most of death cause due to not getting help on time to the injured person. Research has proven that if injured person is not found any option of help then they also lose the power to fight such critical situation due to psychological effect. When vehicle met accident, people are not getting on time support, this delay is the major cause…

Injury Reduction in Vehicle to Pedestrian Collision Using Deployable Pedestrian Protection System in Vehicles

International Centre for Automotive Technology-Jitendra Singh Gaur
  • Technical Paper
  • 2019-28-2551
Published 2019-11-21 by SAE International in United States
Head injuries are the main source of road fatalities when a pedestrian or other vulnerable road user (VRU) such as cyclist or motorcyclist is involved in an accident with the approaching high speed vehicle. The frontal part of a car such as engine hood (bonnet), lower-windshield area and A-pillars are the possible location of head impact in these accidents. The head impact with hard points located in these areas may result in the fatal head injuries. The effect of impact can be reduced by using the deployable pedestrian protection systems (DPPS) such as pop-up hoods and windshield airbag in the vehicle. The study indicates how these systems are effective in reducing the fatalities in pedestrian accidents and how to evaluate the performance of these deployable systems. The pedestrian & VRU road fatalities contribute to more than 33percent of total road fatalities in India. Worldwide regulations for pedestrian protection include the evaluation of head injuries at a relative speed of 35kmph. However, the actual impact can occur at higher speeds many times which results in high…

Performance Assessment of Pyramidal Lattice Core Sandwich Engine Hood for Pedestrian Safety

Mepco Schlenk Engineering College-Dhinesh Balasubramanian, Anish Jafrin Thilak Johnson
Published 2019-10-11 by SAE International in United States
Road accidents are increasing now-a-days, Safety of pedestrian is the great concern. In average, 10% of urban pedestrian accidents are fatal. Statistics show that the impact on front side of cars is the major cause of pedestrian deaths (83.5%). The function of a vehicle’s engine hood is to keep its engine covered and allow access to the engine compartment as required for maintenance and repair. The hood structure not only protects the engine cavity, but also keeps pedestrians away from the parts of that cavity. The absorption capability and stiffness of hood structures are the key points considered when designing a vehicle’s hood. The impact of the pedestrian head on automotive hood results in major injuries and sometimes in death. Conventional engine hood results in greater Head Injury Criterion (HIC) values. GFRP pyramidal lattice core structures are used in automobiles which is used for good energy absorption. GFRP pyramidal lattice core sandwich engine hood absorbs impact energy rather than transmitting it to the head. This will minimize the severity rate of injury of pedestrian during…

Comparative Analysis between American and European Requirements for Electronic Stability Control (ESC) Focusing on Commercial Vehicles

Ford Motor Company-Silvia Faria Iombriller, Wesley Bolognesi Prado, Marco Andre Silva
Published 2019-09-15 by SAE International in United States
Analysis of road accidents has shown that an important portion of fatal crashes involving Commercial Vehicles are caused by rollovers.ESC systems in Commercial Vehicles can reduce rollovers, severe understeer or oversteer conditions and minimize occurrences of jackknifing events.Several studies have estimated that this positive effect of ESC on road safety is substantial. In Europe, Electronic Stability Control (ESC) is expected to prevent by far the most fatalities and injuries: about 3,000 fatalities (-14%), and about 50,000 injuries (-6%) per year.In Europe, Electronic Stability Control Systems is mandatory for all vehicles (since Nov. 1st, 2011 for new types of vehicle and Nov. 1st, 2014 for all new vehicles), including Commercial Vehicles, Buses, Trucks and Trailers.On 2015, NHTSA published Federal Motor Vehicle Safety Standard (FMVSS) No. 136, Electronic Stability Control systems for heavy vehicles, requiring Electronic Stability Control (ESC) systems on truck tractors and buses with a gross vehicle weight rating greater than 11,793 kilograms (26,000 pounds) for implementation in 2017.In South America, CONTRAN Resolution 641/2016 establishes mandatory installation of Electronic Stability and Rollover Control in Commercial…

Factors Affecting the Severity of Motor Vehicle Traffic Crashes in Tunisia

Najran University, Saudi Arabia-Mounir Belloumi
University of Sousse, Tunisia-Fedy Ouni
  • Journal Article
  • 09-07-01-0006
Published 2019-08-19 by SAE International in United States
We investigate the contribution of several variables concerning the severity of accidents involving vehicle occupant and pedestrian victims in Tunisia. In order to investigate the effect of various explanatory variables, Odds Ratio (OR) effects are considered for both serious injury accidents and fatal accidents. The empirical results are of great variety. The vehicle-occupant severity model indicates that male drivers are associated with higher severity levels as compared to female drivers. Added to that, accidents occurring in rainy conditions increase the likelihood of fatal injuries but have no significant effect on other injury severity levels. Among driver contributory factors, a driver under the influence of alcohol or drug is associated with an increased risk of sustaining fatal injuries compared to other driver contributory factors. The season factor shows that accident severity during the summer season is high. Among time of accident, daytime periods indicate a high likelihood of severe injuries as compared to nighttime periods. Another finding of the study is that the day of accident and region of accident increases the probability of severe injury.…
