This paper is aimed at probing into the elements in connection with the dynamical system for China's urbanization under the informatization circumstances and the interaction among those elements. To achieve this end, the paper employs dissipative composition theory and technique. The paper delineates literature with regard to the dynamic system of urbanization and elements thereof. The paper finds...
Informatization is a great motivity to urbanization, but urbanization process is seriously cumbered by urban-rural digital divide in China. Romer's theory of economy growth drag is used for reference, and non-linear regression is applied to build a model of measuring the urbanization process drag from China's urban-rural digital divide. As a research result, the formula of measuring drag is deduced...
AFLP technique was used to elucidate systematic relationships among 26 cultivars of Tree Peony. Six AFLP primer combinations (M+3 and P+3) were used to produce recognizable 757 bands, among which 623 bands are polymorphic. The percentage of polymorphic bands was 82%, suggesting abundant genetic diversity among sect. Moutan. Clustering analysis showed that some cultivars of dwarf and tall peony types...
Based on the SPOT VEGETATION NDVI data, the spatial-temporal variations of vegetation cover in Hexi region of Gansu province were analyzed by using the MVC (Maximum Value Composites) method and the linear regression analysis during 1999 to 2009, the NDVI change trends and characteristics of different land use types were extracted. According to the results, during the last 11 years, the vegetation...
Taking the Landsat MSS(1975) TM & ETM+ (1990, 2000, 2005 and 2010) satellite images as the basic data sources, we extract the distributional information of oasis in the Heihe River Basin during 1975–2010. The results shows that: (1) Oasis expands from 1975 to 2010 and the growing rate especially quickly after the year of 2000, and Oasis reaches the top area of 8218.52 km2 in 2010. (2) Oasis is...
A robust design method applied to microgyroscope is presented which is of automation, efficiency and accuracy. The design target is to maximize the microgyroscope performance, within minimum variation of performance due to uncertainties caused by fabricating errors. Analysis of the tolerance is used to calculate the nominal value and the transmitted variation of the objective function, and the genetic...
Software aging refers to the phenomenon that applications will show growing failure rate or performance degradation after longtime execution. It is reported that this phenomenon usually has close relationship with computing-resource exhaustion. This paper analyzes computing-resource usage data collected on a LAN, and quantitatively investigates the relationship between computing-resource exhaustion...
