in this paper, we present the results of a hierarchical slam/gps/ins/wlfp sensor fusion to be used in navigation system devices. due to low quality of the inertial sensors, even a short-term gps failure can lower the integrated navigation performance significantly. in addition, in gps denied environments, most navigation systems need a separate assisting resource, in order to increase the avail...

In this research, gasoline vapours including Benzene, Toluene, Xylene (BTX) and Total Volatile Organic Compounds (TVOCs) emitted from vent pipes of underground storage tanks (USTs) were measured at six gas stations in Tehran. Thereafter, gas station No. 29 was selected as a pilot station and equipped with a vapour control system. The vapours were measured during the summer of 2013 and winter of...

in this paper a robust road departure avoidance system based on a closed-loop driver decision estimator (dde) is presented. the main idea is that of incorporating the driver intent in the control of the vehicle. the driver decision estimator computes the vehicle look ahead lateral position based on the driver input and uses this position to establish the risk of road departure. to induce a risk...

Reliable communications are essential to provide intelligent services connected cars. For operational services, vehicles in VANET (Vehicle Ad hoc Networks) regularly transfer large amounts of data related vehicular safety. Similarly, V2X (Vehicle-to-Everything) include exchanging information with each other and infrastructure that is, Vehicle-to-Infrastructure (V2I) Vehicle-to-Vehicle (V2V). Th...

THE COST-EFFECTIVENESS OF THE KENTUCKY PILOT PROJECT OF ALLOWING PRIMARY PCI AT HOSPITALS WITHOUT ONSITE CABG

Abstract: This paper introduces a cable-suspended robot, the Vehicle Simulation System, designed for pilot and driver training. The main idea of this work is to make a system that will provide realistic simulations of vehicle motion using virtual reality and a motion platform. A method to produce inertial forces acting on the vehicle user is proposed. A detailed description of the robot’s dynam...

In our country, Student transportations’ security and driving accidents statistics for students is one of the major concerns for relevant organizations such as educational organization. In current year, a system, was named Sepand, was formed in city taxi driver ::::::union:::::: by educational organization, NAJA traffic and city taxi driver ::::::union::::::. In this systems’ plan, ...

this paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

T O simulate the acceleration histories for boost and extreme emergency re-entries of an X-15 altitude mission, a centrifuge program was conducted during lhe months 04 March and April, 1957, by North American Aviation, and the U.S. Navy, in cooperation w i n the U.S. Air Force and the National Advisory Committee for Aeronautics. Its purpose was to provide in,formation regarding complex, oscilla...
