Aiming at the detection of damages in composite components on aircraft, a uniplanar multi-electrode system is introduced. Electric potential distribution in the detection area is solved by finite element analysis, and the sensitivity matrix is calculated. To reconstruct the images with damage information, which is known as an ill-posed inverse problem, the application of optimal vector method is studied...
The large cities such as London, New York and Shanghai are tended to create lots of employment opportunities, but per capita carbon emissions are huge. It is a vital problem about how to provide enough employment opportunities and reduce per capita carbon emissions during the process of urbanization in China. The main of this article think “the Zipf-type city system in area “can achieve the goal of...
This paper takes biomedical industry cluster as the research object, measures the concentration ration and location quotient of the industry clusters of 28 regions in China, then finds out the status of Shanghai biomedical industry cluster. By using the factor analysis, the paper establishes the evaluation index system of industry cluster innovation ability which consists of 4 factors: innovation...
