One of the most important goals in vehicle acoustics is to describe NVH behavior a at sound pressure level using simulation models an early stage development. Different and methods are used for this purpose. To balance advantages disadvantages different methods, it combine models. For virtual description road booming noise passing rough road, we use multibody model excited with elevation profil...

As missions of Unmanned Aerial Vehicles become increasingly elaborate and the level of collaboration between multiple vehicle increases, efficient means of communication enabling data exchange among vehicles and ground elements is the key to a successful accomplishment of the objectives. This paper describes the design, implementation, and integration of a publish/subscribelike message passing ...

In USA, 2002, approximately 3.2 million intersection-related crashes occurred, corresponding to 50 percent of all reported crashes. In Japan, more than 58 percent of all traffic crashes occur at intersections. With the advances in Intelligent Transportation Systems, such as off-the-shelf and in-vehicle sensor technology, wireless communication and ubiquitous computing research, safety of inters...

We present a new, parallel version of the Numerical Electromagnetics Code (NEC). The parallelization is based on a bi-dimensional block-cyclic distribution of matrices on a rectangular processor grid, assuring a theoretically-optimal load balance among the processors. The code is portable to any platform supporting message passing parallel environments such as MPI and PVM where it could even be...

Thanks to the development of electric motors and batteries, the performance of EV is greatly improved in the past few years. The most distinct advantage of an EV is the quick and precise torque response of the electric motors. A further merit of a 4 in-wheel-motor drived electric vehicle (4WD EV) is that, the driving/braking torque of each wheel is independently adjustable due to small but powe...

In this paper, we propose a systematic approach to designing and deploying a RFID Assisted Navigation System (RFIDANS) for VANETs. RFID-ANS consists of passive tags deployed on roads to provide navigation information while the RFID readers attached to the center of the vehicle bumper query the tag when passing by to obtain the data for navigation guidance. We analyze the design criteria of RFID...
