The global growth in urbanisation increases the demand for services including road transport infrastructure, presenting challenges in terms of mobility. These trends are occurring in the context of concerns around environmental issues of poor air quality and transport related carbon dioxide emissions. One out of several ways to help meet these challenges is in the intelligent routing of road tr...

We present a framework for performing collaborative localization groups of micro aerial vehicles (MAV) that use vision-based sensing. The are each assumed to be equipped with monocular camera, and capable communicating other. This approach is developed as decentralized algorithm built in distributed fashion where individual relative pose estimation techniques combined the group localize against...

Micro Air Vehicles (MAVs) will unlock their true potential once they can operate in groups. To this end, it is essential for them to estimate on-board the relative location of their neighbors. The challenge lies in limiting the mass and processing burden needed to enable this. We developed a relative localization method that only requires the MAVs to communicate via their wireless transceiver. ...

This paper presents an overview of the on-going research activities at Shrivenham, aimed at the design of an autonomous flapping-wing micro air vehicle. After introducing the problem of insect wing kinematics and aerodynamics, we describe our quasi-three-dimensional aerodynamic model for flapping wings. This is followed by a brief discussion of some aerodynamic issues relating to the lift-gener...

OBJECTIVE To estimate whether air-bag deployment is associated with an increased risk of adverse pregnancy outcomes. METHODS We performed a retrospective cohort study to assess the effect of air-bag availability and air-bag deployment on the risk of adverse pregnancy outcomes among pregnant, front-seat occupants in motor vehicle crashes in Washington State. Pregnant women involved in motor ve...

Non-aqueous system are well known as solvent or drug suspension vehicles and oleogels micro emulsion with no aqueous phase (anhydrous, non-aqueous oil-in-oil emulsion) have had relatively scant attention yet may have uses as drug reservoir as well as template for the preparation of microemulsion combination with a cosurfactant. Microemulsions have emerged as novel vehicles for drug delivery whi...

This paper reports on our research in developing a micro power generation system based on gas turbine engine and piezoelectric converter. The micro gas turbine engine consists of a micro combustor, a turbine and a centrifugal compressor. Comprehensive simulation has been implemented to optimal the component design. We have successfully demonstrated a silicon-based micro combustor, which consist...

Air traffic system is analyzed from the aspects of system's attributes internal operating mechanisms and external behaviors. A hybrid air traffic simulation model described by the combination of discrete event and continuoustime models is proposed. The simulation model uses Agent-based techniques to describe micro behaviors of the air traffic individuals and integrates micro behaviors into dyna...

AirScope is a micro-scale modeling system as well as a micro-scale air quality monitoring system, which comprises as a micro-scale air quality management system. Importance of micro-scale air monitoring is rising due to the concern about environment near residential places. Traditional monitoring methods are providing overall air quality indexes. However, these methods have limited functionalit...

A scenario where multiple air vehicles are required to prosecute geographically dispersed targets is considered. Furthermore, multiple tasks are to be successively performed on each target, i.e. the targets must be classified, attacked, and verified as destroyed. The optimal, e.g. minimum time, performance of these tasks requires cooperation amongst the vehicles such that critical timing constr...
