The upcoming generation of computer hardware brought several new challenges for software engineers. As in the CPU part, now the multi-core processing is main stream, while the future is massively parallel computing performed on many-core processors. This hardware trend motivates a reconsideration of data-management software architecture, because the highly(More)
OBJECTIVE To assess the effect of respiratory training (RT) on lung function, activity tolerance and acute exacerbation frequency with chronic obstructive pulmonary disease (COPD). DESIGN A randomised controlled trial. SETTING Outpatient clinic and home of the COPD patients, Zhengzhou City, China. SUBJECTS Sixty participants with COPD were randomised(More)
The upcoming generation of computer hardware brought several new challenges for underling software. The number of cores on a chip grows exponentially, allowing for an ever-increasing number of processes to execute in parallel. Therefore, how to efficiently utilize all of the concurrent processing ability provided by multi-core platform becomes critical for(More)
As a famous problem in Combinatorics, small Ramsey number is very hard to solve, because it needs to enumerate all possible graphs in exponential time. We propose a new DNA algorithm for constructing Ramsey graphs, which is a complete process for a small-scale instance to construct all the R(3,3)-graphs of order five from theory to experiment. Based on(More)
