Concerns over the accuracy, availability, integrity and continuity of Global Navigation Satellite Systems (GNSS) have limited the integration of GPS and GLONASS for safety-critical applications. More recent augmentation systems, such as the European Geostationary Navigation Overlay Service (EGNOS) and the North American Wide Area Augmentation System (WAAS) have begun to address these concerns. ...

In Intelligent Transport Systems (ITS), Vehicular Ad-hoc Network (VANET) is one of key wireless technologies, which helps in managing road safety, traffic efficiency, fleet, logistics and transportation. The objective of this paper is to give an overview of the implication of different technologies and placement of VANET in transportation and specifically in logistics. We provide researchers wi...

This paper presents a comprehensive safety approach to the development process of automotive software systems focusing on X-by-Wire applications. A modification to the traditional V-model Development Process is proposed as well as the use of the Rapid Object-Oriented Development Process for Embedded Systems. The system and controls are modelled in UML and then, as part of the safety assurance, ...

a laser is a collimated single wavelength of light which delivers a concentrated source of energy. soon after different types of lasers were invented, investigators began to examine the effects of different wavelengths of laser energy on oral tissues, routine dental procedures and experimental applications. orthodontists, along with other specialist in different fields of dentistry, can now ben...
