 This work was supported by the Academy of Korean Studies of the Republic of Korea in year 2012-2013 (AKS-2010-CAA-2101) Energy security has assumed newfound geopolitical importance at the outset of XXI century (Moran and Russell, 2008). Diminishing fossil fuel supplies have led to fears of energy shortages, while rapid economic and population growth have fuelled the demand for cheap, clean and...

establishment of the gas exporting countries forum in tehran in 2001 has proved to be one of the most important changes in the gas market. gecf has a considerable share in the world liquefied natural gas (lng) trade. facts show that current routes of lng trade are not optimal. hence, in this paper we examine the development of cooperative strategies between countries exporting (lng) and members...

reduction of exhaust emissions is a major research task in diesel engine development in view of increasing concerns regarding environmental protection and stringent exhaust gas regulations. simultaneousreduction of nox emissions and particulate matter is quite difficult due to the soot/nox trade-off and isoften accompanied by fuel consumption penalties. towards this aim, automotive engineers ha...

The objective of this paper is to reinvestigate the relationship between natural gas consumption and economic growth by including foreign direct investment, capital and trade openness in Malaysia for the period of 1971-2012. The structural break unit root test is employed to investigate the stationary properties of the series. We have applied combined cointegration test to examine the relations...

An integrated Artificial Neural NetworkParticle Swarm Optimization (PSO) is presented for analyzing global electricity consumption. To aim this purpose, following steps are done: STEP 1: in the first step, PSO is applied in order to determine world’s oil, natural gas, coal and primary energy demand equations based on socio-economic indicators. World’s population, Gross domestic product (GDP), o...

in this paper, a model based on gmdh type neural network, is used to predict gas price in the spot market while using oil spot market price, gas spot market price, gas future market price, oil future market price and average temperature of the weather. the results suggest that gmdh neural network model, according to the root mean squared error (rmse) and direction statistics (dstat) statistics ...

The substitution of natural gas by a renewable equivalent is an interesting option to reduce the use of fossil fuels and the accompanying greenhouse gas emissions, as well as from the point of view of security of supply. The renewable alternative for natural gas is the so-called green natural gas, i.e. gaseous energy carriers produced from biomass comprising both biogas and Synthetic Natural Ga...
