Wireless networking enabled vehicles can form vehicular ad hoc mesh networks (VMeshs). Using cooperative communication among VMeshs, a local transient information could be "retained" within a given geographic region for a certain period of time, without any infrastructure help. In this paper, we study this "storage capability" of VMeshs. We analyze the scenarios of highway traffic...
This paper presents a method of electromagnetic field mitigation within a cavity with vehicle-like features at one of the GSM bands. The findings can be used for the potential electromagnetic field mitigation within resonant scenarios such as office environments and vehicle cabins.
This paper describes an automated in-vehicle field measurement systems that can be used to acquire 3D electric field distribution generated from wireless antenna sources placed within a passenger vehicle. One prototype is made out of metal and another Delrin. Comparisons between simulated and measured 2D field distribution within a simple cavity correlate well at 870 MHz. Measurements made within...
Dynamic mathematic model with thrust and normal forces in a single sided linear induction motor (SLIM) is established according to the flux distribution in the air gap, which is suitable to gap-length changing during operation of a SLIM. According to the operation characteristics of SLIM, its repulsive component and attractive component in the normal force are analyzed, and then a novel decoupling...
Numerical methods have been used to investigate the possible impact of various dielectric components of vehicles on internal electromagnetic field distributions for frequencies up to 2 GHz. The electrical parameters used in the models were derived from measurements on samples obtained from vehicle components. It is found that the dielectrics investigated have a relatively small impact on the internal...
With the more and more stringent energy crises and greenhouse effect, ldquomore electricrdquo transports are considered to be one of the solutions. The more electric aircraft and hybrid electric vehicle are the representation of ldquomore electricldquo transports. Some aspect of these two means of transport as installed capacity, role of electricity, electric sources, energy storage techniques and...
This paper considers how to design coordination strategies to achieve the coordination in decentralized supply chain, considering pricing, inventory and transportation cost simultaneously under the price sensitive environment. Based on a supplier-Stackelberg game structure, we analyze the non-cooperation decision model and design the algorithm. Then we propose the cooperation decision model and design...
