Cognitive Radio networks and channel sharing are emerging as a new paradigm of communication in multimedia and wireless networks. In this chapter, the authors consider a secondary use application that consists of carrying TDMA traffic between the mobile and the base station for GSM networks over a Cognitive Radio network. Therefore, packets are not only lost by reason of Primary traffic interru...

Modification of seatbelts and their legislation played an important role in reducing morbidity and mortality of occupants in road traffic collisions. We aimed to review seatbelt development, its mechanism of action and its effects. Seatbelts reduce injury by preventing the occupant from hitting the interior parts of the vehicle or being ejected from the car. We have made a linear regression cor...

The traffic-adaptive medium access protocol (TRAMA) is introduced for energy-efficient collision-free channel access in wireless sensor networks. TRAMA reduces energy consumption by ensuring that unicast and broadcast transmissions have no collisions, and by allowing nodes to assume a low-power, idle state whenever they are not transmitting or receiving. TRAMA assumes that time is slotted and u...

background and aim: injuries from traffic accidents are a major public health problem, and the third leading cause of mortality in people aged 1 to 40 years. each year 31.8 persons per hundred thousands of iranians are killed in car accidents. neighboring of north khorasan province with razavi khorasan, a province with a lot of pilgrims caused a large number of passengers travel via north khora...

Background Motorcycle vehicles are frequent in China, especially in the small and medium sized cities. Road traffic collisions involving motorcycles often result in severe injuries. We aimed to identify risk factors for severe injuries in inpatients sustaining motorcycle collisions. Methods Patients with road traffic injuries involving motorcycles who presented to the neurosurgery and orthope...

Traffic signal control is safety-critical for our daily life. Roughly one-quarter of road accidents in the U.S. happen at intersections due to problematic timing, urging development safety-oriented intersection control. However, existing studies on adaptive traffic using reinforcement learning technologies have focused mainly minimizing delay but neglecting potential exposure unsafe conditions....

BACKGROUND Road traffic collision (RTC) is one of many public health problems. Globally, about 1.2 million people die due to RTCs every year. Of these, 85% reside in low- and middle-income countries. Despite low road network density and vehicle ownership, Ethiopia has a relatively high collision record. Collisions in the Addis Ababa and Oromia Regions account for 58% of all fatal collisions in ...

Traffic accidents on urban roads are a major cause of death despite the development traffic safety measures. However, prediction casualties in road has not been deeply explored previous research. Effective forecasting methods for can improve manner accident warnings, further avoiding unnecessary loss. This paper provides practicable model forecast problems, which ten variables, including time c...
