Collision avoidance and road safety applications require highly accurate vehicle localization techniques. Unfortunately, the existing localization techniques are not suitable for road safety applications as they rely on the error-proneGlobal Positioning System (GPS). Likewise, cooperative localization techniques that use intervehicle communications(More)
The generation of hydroxyl (•OH) radicals produced by irradiation of aqueous TiO2 suspensions was investigated by electron paramagnetic resonance (EPR) and product analysis employing a stable free nitroxide radical (3-carboxyproxyl) as a spin trap of •OH. Product analysis demonstrated that the attack of •OH on 3-carboxyproxyl produces a diamagnetic product(More)
Road safety applications in Vehicular Ad Hoc Networks (VANETs) necessitate highly accurate vehicle localization techniques. Unfortunately, Global Positioning System (GPS)based localization techniques do not only suffer from the lack of ubiquitous GPS coverage but also are susceptible to high localization errors (10 m to 30 m). Consequently, such techniques(More)
