In this way basing on results previous known researches basic questions are discussed. manufactured and tested practical application elements different purpose exemplified. possibilities such existing presented. Much attention is paid to manufact...

In this study, a decomposition and emissions matrix is developed to identify the roles (giver or taker) played by the sectors in the greenhouse gas emissions for the economy of Beijing in China. Our results indicate that services were the most important emitter if we consider the total (direct and indirect) emissions. In addition to Construction, Scientific studies and technical services and Fi...

The economic geography of the United States’ energy landscape changed rapidly with domestic expansion of the natural gas sector. Recent work with smooth transition parameter models is extended to an establishment location model estimated using Poisson regression to test whether expansion of this sector, as evidenced by firm location decisions from 2005 to 2010, is characterized by different gro...

Electrochemical hydrogen pump using ceramic proton conductor has been investigated to discuss its application for the blanket tritium recovery system of the nuclear fusion reactor. As the series of those work, the transportation experiments of H2-D2 mixture via ceramic proton conductor membrane have been carried out. Then, the phenomenon that was caused by the exchange reaction between the deut...

with high energy density, which makes it useful for storage and transportation over long distances from the gas fields to the consumers. LNG is recovered from natural gas in largescale liquefaction plants. Process automation is a key issue in LNG plants to ensure cost efficient plant operation and high product quality. Process analyzer deliver important data therefore. Siemens Sensors & Communi...

To mitigate climate change, city authorities are developing policies in areas such as transportation, housing and energy use, to reduce greenhouse gas emissions. In addition to their effects on greenhouse gas emissions, these policies are likely to have consequences for the wellbeing of their populations for example through changes in opportunities to take physical exercise. In order to explore...

When a natural gas pipeline ruptures, the adjacent automatic line control valves (ALCVs) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ALCV action. If the DPS is not properly adjusted, the ALCV may mistakenly close or it may not take any action at proper time. This study focused on...
