How sustainable is globalisation?

In 1957, at a high point in the Cold War, the Russians launched the fi rst satellite – the Sputnik. The fact that the Russians had got into space fi rst came as a great shock to the Americans, who responded with a crash investment programme in the training of scientists and technologists. Jahoda calculated that if this increase in human resource investment had been sustained over the decades, b...

How Sustainable Is Concrete?

An analysis was carried out to determine whether concrete is a sustainable housing material. Sustainability generally means having no net negative impact on the environment, and this analysis compared the environmental impact of producing concrete and steel. To make this comparison, we first designed a simple reinforced concrete beam and a steel I-beam with the same moment capacity, and we then...

How Scalable Is Domain

1 Introduction The convergence rates and, therefore, the overall parallel eeciencies of additive Schwarz methods are often dependent on subdomain granularity. Except when eeective coarse-grid operators and intergrid transfer operators are known, so that optimal multilevel preconditioners can be constructed, the number of iterations to convergence tends to increase with granularity for elliptica...
