The current flight delay not only affects the normal operation of flight, but also spreads to downstream flights through schedule, resulting in a wide range delays. analysis and prediction propagation advance can help civil aviation departments control rate reduce economic loss caused by Due small number data samples that constitute chains, it is difficult construct chain data. In recent years,...

We propose an algorithm for gate-delay fault diagnosis. It is based on the inject-and-evaluate paradigm [1], in which the fault site(s) are predicted through a series of injections and evaluations. Unlike the backtrace algorithm that predicts the fault site by tracing the syndrome at a faulty output back into the circuit, this approach mainly relies on the six-valued simulation. In such a forwa...

Current speech recognition systems use mainly amplitude spectrum-based features such as MFFC for acoustic feature parameters, while discarding phase spectral information. The results of perceptual experiments, however, suggested that phase spectral information based on long-term analysis includes certain linguistic information. In this paper, we propose the use of phase features based on long-t...

This paper develops the theory and digital waveguide implementation for modeling threedimensional (3D) sound emission from wind instrument air columns. It is shown that the current acoustic theory regarding sound radiation from ducts and holes can be implemented in the digital waveguide context using properly designed digital filters. Each radiating sound source or hole requires a firstor secon...

This paper explores the inherent delays of airline schedules resulting from limited buffer times and stochastic disruptions in airline operations. The reliability of airline schedules is discussed and a set of measuring indices is developed to evaluate schedule reliability. It is found that significant gaps exist between the real operating delays, the inherent delays (from simulation) and the z...

Existing techniques can geolocate an IP address to a metropolitan area. Through simulation, we evaluate the performance of these existing techniques within a metropolitan area network. We identify differences between metropolitan area networks and the wide area network. We describe and evaluate new techniques which are designed specifically for use on metropolitan area networks. We present Hop-...

Timing Speculation (TS) is a widely known method for realizing better-than-worstcase systems. Aggressive clocking, realizable by TS, enable systems to operate beyond specified safe frequency limits to effectively exploit the data dependent circuit delay. However, the range of aggressive clocking for performance enhancement under TS is restricted by short paths. In this paper, we show that incre...

Underwater sensor networks (UWSN) resemble terrestrial sensor networks in many aspects. However, the high propagation delay and limited bandwidth make terrestrial sensor network’s protocols unsuitable for UWSN. For instance, routing protocols proposed for terrestrial networks are not applicable in an underwater network. Therefore, enormous efforts have been made for designing efficient protocol...
