Abstract: We report experimental studies on the initiation of detonations by hypervelocity projectiles in hydrogen-oxygen-nitrogen mixtures. The experimental facility T5 at Caltech was modified to launch 25-mm diameter projectiles at speeds around 3000 m/s. Flow visualization and pressure measurements are reported for several mixture conditions. A clear transition between shockinduced combustio...

We consider a class of dynamic discrete-time two-player zero-sum games. We show that for a generic cost function and each initial state, there exists a pair of overtaking equilibria strategies over an infinite horizon. We also establish that for a generic cost function f , there exists a pair of stationary equilibria strategies (xf ,yf ) such that each pair of “approximate” equilibria strategie...

While intelligent transport systems are preparing to welcome connected and automated vehicles (CAVs), it is uncertain which algorithms should be employed manage them. In particular, even though remarkable improvements in telecommunication technologies, such as vehicle-to-everything (V2X), enable communication computation sharing among different agents, e.g. infrastructures, distributed control ...

Abstract As intelligent vehicles usually have complex overtaking process, a safe and efficient automated system (AOS) is vital to avoid accidents caused by wrong operation of drivers. Existing AOSs rarely consider longitudinal reactions the overtaken vehicle (OV) during overtaking. This paper proposed novel AOS based on hierarchical reinforcement learning, where reaction given data-driven socia...

Background & Aims of the Study: Risky driving behaviors are a set of actions that put drivers at the risk of death or injuries which are caused by the violations of legal standards. These kinds of behaviors are the key factor leading to a higher risk of traffic crashes and injuries. The present study aimed to investigate the situation of some high-risk traffic behaviors and the related factors ...

Record and Replay technique has been proved an effective solution to cyclic debugging of nondeterministic parallel program. Because of nondeterminism, a parallel program given the same inputs on successive runs can sometimes produces different results. In this paper; an optimal record and replay technique is presented, which produces less overhead in time and space by using the non-overtaking r...

Bio-inspired energy models compute motion following the guidelines suggested by the neurophysiological studies of V1 and MT areas of monkeys and human behaviour that use neural populations to extract the local motion structure through local competition of MT like cells. In this paper we present a neural structure that works as dynamic filter on the top of this MT layer for image segmentation an...
