Determining the Extent of Territorial Transport Services When Using Rail 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...

ESTIMATION OF RADIATION LOSS FROM STELLARATORS USING NEOCLASSICAL TRANSPORT THEORY

The radiation power loss from a magnetically confined plasma in a stellarator has been calculated using neoclassical particle and energy fluxes in an energy balance equation. We could obtain a power loss of about 34% of the total input power by numerical calculation. This fraction of the power loss has been found to be in good agreement with the experimentally measured values of 30-40% for...

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...
