NEEDS AND POSSIBILITIES OF USING RAIL TRANSPORT IN MILITARY TRANSPORT

Rail Transport and Energy Consumption

This paper attempts to portray the present unstable situation of handling passengers and freight inside Iran as well as to represent a clear view of the rail transport features that have given this mode of transport a special place among the transport system. In this paper the rate of fuel consumption as a main pivotal item has been evaluated as well as the amount and cost of fuel economized th...

Automatic Passengers Counting In Public Rail Transport Using Wavelets

Previously, we introduced a passengers’ counting algorithm in public rail transport. The main disadvantage of that algorithm is it lacks automatic event detection. In this article, we implement two automatic wavelet-based passengers counting algorithms. The new algorithms employ the spatial-domain Laplacian-of-Gaussian-based wavelet, and the frequency-domain applied Non-Linear Difference of Gau...

Discrete optimization in public rail transport

Single-Car Routing in Rail Freight Transport

Cars in rail freight service follow prescribed routes from their origin via intermediate shunting yards to their destination. The goal in designing such routes is to reduce the number of trains and their travel distances. Various real-world hard constraints make the problem difficult to formulate and also to solve. We present integer programming formulations for this car routing problem arising...

Simulations of transport in one dimension

Advection-dispersion equation is solved in numerically by using combinations of differential quadrature method (DQM) and various time integration techniques covering some explicit or implicit single and multi step methods. Two different initial boundary value problems modeling conservative and nonconservative transports of some substance represented by initial data are chosen as test problems. ...
