BACKGROUND Childhood body mass index (BMI) and obesity prevalence have been associated with exposure to secondhand smoke (SHS), maternal smoking during pregnancy, and vehicular air pollution. There has been little previous study of joint BMI effects of air pollution and tobacco smoke exposure. METHODS Information on exposure to SHS and maternal smoking during pregnancy was collected on 3,318 ...

Receptor-oriented source apportionment models are often used to identify sources of ambient air pollutants and to estimate source contributions to air pollutant concentrations. In this study, a PCA/APCS model was applied to the data on non-methane hydrocarbons (NMHCs) measured from January to December 2001 at two sampling sites: Tsuen Wan (TW) and Central & Western (CW) Toxic Air Pollutants Mon...

Vehicular networking has become a significant research area due to its specific features and applications such as standardization, efficient traffic management, road safety and infotainment. Vehicles are expected to carry relatively more communication systems, on board computing facilities, storage and increased sensing power. Hence, several technologies have been deployed to maintain and promo...

With the rapid growth and evolution of the vehicular network with the highly increasing demand of vehicular traffic management, vehicular infotainment applications, and the vehicular cloud computing, massive vehicular information is required to be downloaded from roadside-deployed gateways. With the nature of high mobility and intermittent connectivity, it is challenging to provide a highly rel...

The past decade has witnessed a growing interest in vehicular networking and its vast array of potential applications. Increased wireless accessibility of the Internet from vehicles has triggered the emergence of vehicular safety applications, locationspecific applications, and multimedia applications. Recently, Professor Olariu and his coworkers have promoted the vision of Vehicular Clouds (VC...

The vehicular internet will drive the future of vehicular technology and intelligent transportation systems (ITS). Whether it is road safety, infotainment, or driver-less cars, the vehicular internet will lay the foundation for the future of road travel. Governments and companies are pursuing driver-less vehicles as they are considered to be more reliable than humans and, therefore, safer. The ...

Urban and peri-urban growth is increasing world-wide and Europe is now one of the most urbanized continents in the world. Oslo is one of the fastest growing cities in Europe. This creates pressure on its infrastructure, including traffic and environmental urban quality. Additionally, vehicular traffic is a major contributor to CO2 emissions, which impacts climate change. It is recognized that a...

Vehicular Adhoc Networks (VANET) are gaining importance in vehicular networks and attracting an increasing attraction from both industry and research communities. Mobility Management is one of the most important and challenging research issue in vehicular networks which support various applications of Intelligent Transportation System (ITS). A specific mobility management solution is required f...

Ambient air pollution in urban and industrial areas in Greece was a serious environmental problem which was connected with rapid urbanization of cities, anarchic housing development without basic infrastructures and increases of motor vehicle fleet in urban regions. Especially Athens, witnessed severe air pollution problems in the decades 1960s‘-1970s‘ and the formation of the infamous brown-ye...
