Due to the increasing recognition of global climate change, the building and construction industries are under pressure to reduce carbon emissions. A central issue in striving towards reduced carbon emissions is the need for a practicable and meaningful yardstick for assessing and communicating...

Entropy generation, which is available exergy destruction, is an important subject in fields of energy management and thermal engineering. With the fast-growing rate of composite media applications in both industries and academic researches, it is necessary to study these media from the second...

Precise prediction of thermal processes is one of the major concerns in the field of heat transfer and within energy research communities. It has been proven that using LTE (local thermal equilibrium) conditions within a porous medium may give researchers erroneous data. From another point of...

Malaysia is a coastal country, with a long coastline in Peninsular Malaysia connecting the Strait of Malacca in the west and the South China Sea to the east. The Strait of Malacca is a well-known waterway allowing the continuous supply of oil by tankers from the Middle East to the Far East, such...

The need for renewable energy is a global demand due to both the economic factors and the environmental concerns. Malaysian government has been supportive on the research and development in the renewable energies. Renewable Energy Act (2011) and Sustainable Energy Development Authority Act...

In this paper, emulsion fuels from crude bio-oil and its molecular distillation fractions were prepared by single ultrasonic and ultrasonic-mechanical emulsification. The results showed that the emulsions from crude bio-oil and 0# diesel had the best stability, with a stability time of 31 days....

In the present paper, a five-column heat integrated methanol distillation scheme is proposed with the aid of process simulation and pinch analysis. Unlike the popular four-column (or 3 + 1 column) scheme, a medium-pressure column is added after the light ends column in this novel scheme. The...

As a stark contrast to the diminishing media profile of the UN climate change talks, the global manufacturers appear to have become more carbon aware than ever before. Carbon audits have been carried out within many corporations to assess the carbon intensity of production processes. This is...

Calcined dolomite is a good catalyst in terms of its activity for gasification of residue derived from biomass hydrolysis for hydrogen production, whereas its fragility can cause trouble during operation. A novel modification method aimed at improving the strength of the calcined dolomite has...

This paper embeds security design in a model of evolutionary learning. We consider a competitive and perfect financial market where agents, as in Allen and Gale (1988), have heterogeneous valuations for cash flows. Our point of departure is that, instead of assuming that agents are endowed with...
