As any frequent flier is no doubt aware, flight delays and cancellations are a largely inevitable part of commercial air travel. In the past ten years, only twice have more than 80% of commercial flights arrived on-time or ahead of schedule. Punctuality is an issue for all major carriers, with some struggling more than others: through September 2008, American Airlines flights were on time just ...

A semi-empirical mathematical model for predicting the physical part of ignition delay period in the combustion of diesel engines with swirl is developed. This model is based on a single droplet evaporation model. The governing equations, namely, equations of droplet motion, heat and mass transfer were solved simultaneously using a Runge-Kutta step by step method. The computation was executed u...

A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...

In order to improve the performance of network traffic prediction model, a novel network traffic prediction model is proposed in this paper which embedding dimension and time delay of network traffic time series are jointly optimized by genetic algorithm. The optimail embedding dimension and time delay are used to establish the one-step and multi-step based on RBF neural network, finally, the s...
