The brakes must be strong enough to stop the vehicle within a minimum distance in an emergency. The driver must have proper control over the vehicle during emergency braking and vehicle must not skid. The brakes must have good antedate characteristics their effectiveness should not decrease with prolonged application and thus it demand that the cooling of the brakes should be very efficient. Fo...
Computing real-time road condition is really tough and it is not achieved using GPS. However, a malicious node can create multiple virtual identities for transmitting fake messages using different forged positions. A malicious vehicle can disseminate false traffic information in order to force other vehicles and vehicular authorities to take incorrect decisions. To overcome these difficulties w...
One of the key challenges facing distribution network operators today is expected increase in electric vehicles. The increased load from EV charging will result assets becoming “thermally overloaded” due to higher operating temperatures. In addition issue load, we have a limited understanding behavior and performance their potential accept load. It has been well acknowledged that EVs loading le...
The response time to emergency situations in urban areas is considered as a crucial key limiting material damage or even saving human lives. Thanks their “bird's eye view” and flexible mobility, Unmanned Aerial Vehicles (UAVs) can be promising candidate for several vital applications. Under these perspectives, we investigate the use of communicating UAVs detect any incident on road, provide res...
The lack of multistakeholder cooperation is one the main challenges faced by emergency medical services (EMS). Especially in ambulance routing process, inactive traffic operators fail to provide coordination prioritize ambulance, while ignoring choice hospitals will lead inevitable patient transfer between hospitals. To efficient decision support for EMS, this paper considers daily problems a n...
----Every day around the world, a large percentage of people die from traffic accident injuries. An effective approach for reducing traffic fatalities is: first building automatic traffic accident detection system, second, reducing the time between when an accident occurs and when first emergency responders are dispatched to the scene of the accident. Recent approaches are using built-in vehicl...
crush injury of an extremity occurs when a limb is compressed between two hard surfaces, to the point where vascular supply is impaired and vulnerable tissues undergo necrosis. most commonly, limbs are crushed during auto versus pedestrian accidents, motor vehicle crashes, and industrial accidents. however, during natural disasters such as earthquakes, buildings collapse, landslides, mine cave-...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
