Distributed versus Lumped Optimization of Cropping Pattern and Water Resources Utilization

Distributed versus Lumped Optimization of Cropping Pattern and Water Resources Utilization

Several whole-farm agro-economic optimization models have been developed to deal with lumped planning issues in the agriculture sector. However, these models cannot be used to devise appropriate management strategies at land parcel level, because of the differences between farm characteristics, and the increased complexity of the hydrological processes. Based on Spatial Farm Database (SFD) whic...

Lumped Versus Distributed RC and RLC Interconnect Impedances

Abstract— A Fourier analysis of on-chip signals in CMOS integrated circuits is presented in this paper. It is demonstrated that on-chip signals can be approximated by a Fourier series up to the th harmonic component. The effective load impedance characterizing a distributed RC and RLC line driven by a CMOS logic gate is based on a Fourier analysis of the on-chip signals. The voltage waveform ba...

determining the optimum cropping pattern in same direction with water resources management of mashhad-chenaran plain

abstract in refrence to un appropriate time and place dispersal of precipitation in iran and having low efficiency in agriculture, water as the most limitative factor in agriculture is discussing. in this study, the existing pattern of mashhad-chenaran plain is considering and with gathering data related to 1388, with target of decrease in water consuming, optimum and nearly optimum cropping pa...

Effects of investment in water-saving technology on cropping pattern and employment

optimal cropping pattern for water resources management in sistan region of iran using goal programming method

the optimal cropping pattern for sistan water resources management was determined through a goal programming technique within the gams programming environment. results showed that the optimum cultivation area and net profit of the agricultural sector in the sistan region could increase up to 18.1 and 39.8%, respectively, compared to the current status. an increase in the farm irrigation efficie...
