Suitable selection of the emergency alternatives is a critical issue in emergency response system of Unattended Train Operation (UTO) metro system of China. However, there is no available method for dispatcher group in Operating Control Center (OCC) to evaluate the decision under emergency situation. It was found that the emergency decision making in UTO metro system is relative with the prefer...

n Flight delays are now a major problem in the U.S. National Airspace System. A significant fraction of these delays are caused by reductions in en route capacity due to severe convective weather. The Corridor Integrated Weather System (CIWS) is a fully automated weather analysis and forecasting system designed to support the development and execution of convective weather impact mitigation pla...

The Tiger (Panthera tigris) population in India has undergone a sharp decline during the last few years. Of the number of factors attributed to this decline, habitat fragmentation has been the most worrisome. Wildlife corridors have long been a subject of discussion amongst wildlife biologists and conservationists with contrasting schools of thought arguing their merits and demerits. However, i...

OBJECTIVE To analyze the long-term changes in maxillary arch widths and buccal corridor ratios in orthodontic patients treated with and without premolar extractions. METHODS The study included 53 patients who were divided into the extraction (n = 28) and nonextraction (n = 25) groups. These patients had complete orthodontic records from the pretreatment (T1), posttreatment (T2), and postreten...

Fundamental characteristics of decentralized separation control in a high density air corridor are discussed. A high density air corridor is expected to be an air space where aircraft capable of airborne self-separation are allowed to fly into the same direction. Some decentralized control algorithms are indispensable for its operational safety and a large traffic throughput. In this study two ...

This study deals with the influence landmark information has on the foraging behaviour of the desert ant, Cataglyphis fortis, especially with the interaction of such landmark information with the ants' path integration system. We show in the first experiment that desert ants that are captured immediately after leaving their nest and then transferred to a remote test area search for the nest rat...

The need for differentiated levels of Quality of Service in the Internet has motivated the development of several QoS mechanisms. This paper describes Paris Metro Pricing (PMP), the simplest differentiated services solution, proposed by Odlyzko [1]. In PMP, the service differentiation would result implicitly from dividing the network into several logically separate best-effort channels with dif...
