Assessing the potential to bring 100 years of aeronautics knowledge to the entrepreneur’s desktop to enable a design environment for emerging vertical lift vehicles is one goal for the NASA’s Design Environment for Novel Vertical Lift Vehicles (DELIVER). As part of this effort, a system study was performed using a notional, urban aerial taxi system to better understand vehicle requirements alon...

In this paper an optimal controller is proposed for a self-balancing electrical vehicle called Segway PT. This vehicle has one platform and two wheels on the sides and the rider stands on the platform. A handlebar, as a navigator, is attached to the body of Segway, with which the rider controls the vehicle. Since Segway uses electrical energy produced by batteries, resource consumption manageme...

Unmanned and autonomous systems require a great deal of human trust, especially in order to gain acceptance for high-risk mission applications. In the aerial domain, loss of vehicle control, crashing or leaving the safety of the designated range can present a hazard to human safety as well as property. This represents a key barrier in current safety review processes when considering an experime...

in this paper, the 1/4 vehicle model have been simulated. the vehicle body acceleration using optimal control has been optimized. the vehicle ride comfort is achieved by using robust control, and it has been compared with optimal control. the active suspension can help the vehicle to have a good dynamic behavioral. in this paper, two degrees of freedom dynamic vibration model of a general vehic...

This paper proposes a method of improving reception of digital satellite broadcasting in a moving vehicle. According to some studies, the antennas used for mobile reception will be smaller in the next generation and reception will be more difficult because of a fading multipath channel with delays in a low carrier-to-noise ratio. Commonly used approaches to reduce the inter symbol interference ...

Small-scale pilot projects have demonstrated that integrated population, health and environment approaches can address the needs and rights of vulnerable communities. However, these and other types of health and development projects have rarely gone on to influence larger policy and programme development. ExpandNet, a network of health professionals working on scaling up, argues this is because...

The connected vehicle (CV) system promises unprecedented safety, mobility, environmental, economic and social benefits, which can be unlocked using the enormous amount of data shared between vehicles and infrastructure (e.g., traffic signals, centers). Real-world CV deployments including pilot deployments help solve technical issues and observe potential benefits, both of which support the broa...
