Aqueous environments contaminated with diesel components pose a threat to the native biota due to the intrinsically toxic nature of the many hydrocarbon compounds present. In the event of diesel being released into an aqueous environment it is imperative that the contaminant is recovered in a rapid manner to ensure the safety of aquatic organisms as well as to maintain desired water quality. Th...

This article discusses the design process for a formation flight experiment constructed at Cornell University. The primary motivation for the testbed is to explore control design and analysis for interconnected systems. These systems are comprised of many similar units that interact directly with their nearest neighbors, and that have sensing and actuating capabilities at every unit. The result...

This paper presents a method for analysis of automated highway throughput for AHS designs, including those with platooning. Simulation results are presented which show that increased information leads to higher throughput, and that a platooning design will have higher throughput than any individual vehicle design.

In this paper, we establish a basic dimension theory for rigid subanalytic sets, and we prove a Smooth Stratiication Theorem for such sets, in all characteristics.

THE PROBLEM: MOTORCAR MORALITY AND AUTOMOBILE AGEING Advances in modern technology mean that cars are living longer than ever before. This raises important end-of-road-life issues, as it becomes increasingly difficult to provide leaded fuel and shelter for our hydraulically challenged, ageing automobile population. The garage is full, and off-street parking is beyond the financial scope of most...

We show that a large class of non–metric, non–symplectic affine holonomies can be realized, uniformly and without case by case considerations, by Weyl connections associated to the natural AHS–structures on certain generalized flag manifolds.

The use of a mass balance equation assists in clarifying the contribution of automotive-emitted lead to the regional and global problems of the distribution of this element, by taking into account the physicochemical transformation processes operating on the lead during its transport along the various environmental pathways. The technical factors which govern the emission of such lead from auto...

In the standards about the contour dimension of automobile in most countries, the height difference of body symmetrical points or body inclination angle of automobile was specified. To improve the vehicle performance and operation safety, a measurement method of car body inclination angle was studied. According to the camera calibration and the distance between camera and automobile, the front ...

در طراحی یک میل گاردان فلزی یکی از مهمترین عوامل محدود کننده، سرعت بحرانی می باشد که بعضا طراح را مجبور به چند تکه کردن میل گاردان می کند. سرعت بحرانی یک محور با مجذور طول آن نسبت معکوس و با جذر سفتی ویژه مواد به کار رفته در آن رابطه مستقیم دارد. با توجه به اینکه سفتی ویژه مواد کامپوزیتی بیشتر از فلزات است. یک میل گاردان کامپوزیتی نسبت به یک میل گاردان هم اندازه فلزی در سرعت دورنی بالاتری رزونا...
