We present an asymptotically optimal algorithm to locate all the axes of mirror symmetry of a planar i t The algorithm was derived by reducing the 2-D symmetry problem to linear pattern-matching. Opt gorithms for finding rotational symmetries and deciding whether a point symmetry exists are also prese
Cropping system level study is not only useful to understand to overall sustainability of agricultural system, but also it helps in generating many important parameters which are useful in climate change impact assessment. Considering its importance, Space Applications Centre, took up a project for mapping and characterizing major cropping systems of Indo-Gangetic Plains of India. The study are...
This paper presents a model for constrained multiobjective optimization of mixedcropping planning. The decision challenges that are normally faced by farmers include what to plant, when to plant, where to plant and how much to plant in order to yield maximum output. Consequently, the central objective of this work is to concurrently maximize net profit, maximize crop production and minimize pla...
Wang Shengfeng,Xu Jianxin,Yang Shuqin,Jia ping (North China University of Water Resources and Electric Power, Zhenzhou, P. R. China) Email:[email protected] Abstract:Winter wheat and summer maize were important grain crops in China,and winter wheat-summer maize continuous cropping was the main tillage method in north China.According to field experiment datas, Jensen models of winter wheat and...
Multiple cropping, a common practice of intensive agriculture that grows crops multiple times in the agricultural land in one growing season, is an effective way to fulfill the food demand given limited cropland areas. Deriving cropping cycles from satellite data provides the spatial distribution of cropping intensities that allows for monitoring of the multiple cropping activities over large a...
