Oxyfuel combustion technology is one of the near-zero emission clean coal technologies, which can realise the large-scale CO2 capture, low NOx emission, and easier removing of SO2. This paper describes the characteristics of pyrolysis, gasification and combustion of coals and chars in oxyfuel...

The authors investigate the relationship between foreign technology imports and economic growth in developing countries. They develop an intertemporal endogenous growth model that explicitly accepts foreign technology imports as a factor of production. The model establishes a link between the...

A family of new conjugate gradient methods is proposed based on Perry’s idea, which satisfies the descent property or the sufficient descent property for any line search. In addition, based on the scaling technology and the restarting strategy, a family of scaling symmetric Perry conjugate...
