Electric Trains and Japanese Technology
1872 marked the start of commercial railway operations in Japan, nearly half a century after railways had started in the UK. However, electric railways did not appear until 1890 at an exhibition held in Ueno, 10 years after the start in Europe but only 2 years after Frank J. Sprague (1857–1934) started running electric streetcars in Richmond, USA, in 1888, which triggered the rapid spread of el...
متن کاملApplication of Demand Response Programs to Heavy Industries: a Case Study on a Regional Electric Company
In recent years, incremental rate of electrical demands made many challenges for policy makers of power systems. Besides, due to economic crisis and environmental concerns about the air pollution, the new investments in thermal power generation units have experienced a noticeable reduction. For this reason, the power system operators should propose novel approaches to make a balance between inc...
متن کاملNumerical method for Calculating the Dynamic Behaviour of a Trolley Wire Overhead Contact System for Electric Railways
A numerical method is described that has been used for predicting the dynamic behaviour of a trolley wire overhead contact system when disturbed by the pantograph on the train roof. The vertical motion of the trolley wire is given by the solution of a fourth order partial differential equation and that of the pantograph is given by the solution of ordinary differential equations, these two solu...
متن کاملPlasma membrane permeabilization by trains of ultrashort electric pulses.
Ultrashort electric pulses (USEP) cause long-lasting increase of cell membrane electrical conductance, and that a single USEP increased cell membrane electrical conductance proportionally to the absorbed dose (AD) with a threshold of about 10 mJ/g. The present study extends quantification of the membrane permeabilization effect to multiple USEP and employed a more accurate protocol that identif...
متن کاملSome Sustainability Aspects of Energy Conversion in Urban Electric Trains
The paper illustrates some aspects of energy conversion processes during underground electric train operation. Energy conversion processes are explained using exergy, in order to support transport system sustainability. Loss of exergy reflects a loss of potential of energy to do work. Following the notion that life in Nature demonstrates sustainable energy conversion, we approach the sustainabi...
