Studying and improving intermediate rail fastening of 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...

Improving the Security of Dual-Rail Circuits

Dual-rail encoding, return-to-spacer protocol and hazard-free logic can be used to resist differential power analysis attacks by making the power consumption independent of processed data. Standard dual-rail logic uses a protocol with a single spacer, e.g. all-zeroes, which gives rise to power balancing problems. We address these problems by incorporating two spacers; the spacers alternate betw...

Shared Intermodal Terminals and the Potential for Improving the Efficiency of Rail-Rail Interchange

While largely due to conditions outside their control, the configuration and setting of current intermodal rail terminals contribute to congestion and increased freight handling volumes that have resulted in additional transportation costs for shippers and carriers. Although a substantial body of research has focused on improving the efficiency of port operations and multi-modal freight shipmen...

Technical Note: Experiences of Studying Airborne Wear Particles from Road and Rail Transport

Airborne particles and their adverse effects on air quality have been recognized by humans since ancient times. Current exhaust emission legislations increase the relative contribution of wear particles on the PM levels. Consequently, wearbased particle emissions from rail and road transport have raised concerns as ground transportation is developing quickly. Although scientific research on air...
