In this paper, Multi-Microgrids (MMG) are considered as future smart distribution grids, in which small scale energy resources (SSER) are main power generation units with small scales. Optimal operation of microgrids in defined intervals is carried out to achieve economic conditions in distribution systems. The defined operating problem is optimized using a heuristic algorithm considering uncer...

the study carried out an assessment of agricultural land management practices in food crops production among small scale farmers in kwara sate, nigeria. specifically, the study determined the socio economic characteristics of crop farmers in kwara state; ascertained the cropping patterns common among them; highlighted the soil conservation methods adopted by the farmers; examined the relationsh...

in this paper, a numerical solution procedure is presented for the forced vibration of a piezoelectric nanowire under thermo-electro-mechanical loads based on the nonlocal elasticity theory within the framework of timoshenko beam theory. using hamilton’s principle, the nonlocal governing differential equations are derived. the governing equations and the related boundary conditions are discreti...

membrane-based technologies have increasingly been chosen in desalination processes, which is evidenced by the increase of large-scale plants constructed in recent years. indeed, several appropriate strategies should be considered to minimize problems faced during the construction, such as membrane system designs, area requirement, energy requirement, operation and maintenance, and environmenta...

Tidal energy is a very rich Marine resource, which has high concentration, small geometric scale and strong predictability. The research status, development utilization of tidal current turbine at home abroad are expatiated, two methods for hydrodynamic characteristics turbine, including numerical calculation simulation experiment, introduced, certain significance to the performance optimizatio...

Recent work suggests that global variation in toolkit structure among hunter-gatherers is driven by risk of resource failure such that as risk of resource failure increases, toolkits become more diverse and complex. Here we report a study in which we investigated whether the toolkits of small-scale farmers and herders are influenced by risk of resource failure in the same way. In the study, we ...
