近日,中国地质大学环境学院顾延生教授团队题为《中国西南热带地区过去千年来ENSO关联的干旱与印度夏季风变化》(ENSO-related droughts and ISM variations during the last millennium in tropical southwest China)的学术论文刊发在杂志《Climate Dynamics》上,该文为深刻理解中国西南热带地区印度夏季...
Turkey is located in Africa-Eurasia-Saudi Arabian plate converged areas with surrounding by the Black Sea and the Mediterranean Sea. Apart from its tectonic conditions, the climate is complexly varyin...
Weight gain and the resulting obesity is fundamentally the consequence of chronic energy imbalance, with energy intake exceeding energy expenditure, which then leads to excessive energy (fat) storage.
The present study examines the macrostructure and density of larch wood and possible influences on the productivity of larch stands. The studies were conducted in the middle and sub-tundra taiga in th...
Groundwater utilization and protection are crucial for sustainable urban development. This is especially true for Beijing, where groundwater is an important source for urban water supply. In this stud...
In this study, we used the NDVI time-series datasets to investigate variations in the starting dates of growing season (SGS) in China's cropland from 1983 to 2002. To do so, a smoothing algorithm base...
Multiple cropping system, characterized by cropping index, is of significant importance to Chinese food production and security.Owing to the changing nature conditions and human activity, cropping ind...
Various methods of analysis and dataset have been used for urban studies. However, used urban data often has low spatial resolution,especially regional statistics, though statistical data can cover la...
Protecting the living environment has become one of the greatest human concerns; sudden increase of population, industry and technology development, unrestrained over consumption of the citizens and c...
This paper describes a simple comparison of the distributions of land cover features identified from volunteered data contributed by different social groups in this case comparing two groups of Geo-...
What image classification does is to assign pixel to a particular land cover and land use type that has the most similar spectral signature. However, there are possibilities that different methods or...
We investigate the convex-concave procedure (CCP), a local heuristic that utilizes the tools of convex optimization to find local optima of difference of convex (DC) programming problems. The class of...
This paper focuses on wing optimization via control theory using a multi-point design method. Based on the design methodology previously developed for wing section and planform optimization at a speci...
This paper describes the formulation of optimization techniques based on control theory for aerodynamic shape design in inviscid compressible ow modelled by the Euler equations. The design methodology...
We perform a combined stochastic-deterministic analysis of local site response using two computer codes, an equivalent linear analysis program SHAKE and a fully nonlinear finite element code SPECTRA. ...
