concerns related to conservation of fossil fuels and greenhouse gas emission has increased energy balance studies in crop production systems. in the present study, six wheat (triticum aestivum) fields were selected from east and west of gorgan, golestan province, iran. during three consecutive growing seasons, data were gathered on energy use in all production practices. then, all the energy us...

in this paper smart operation of micro energy hub is presented. energy hub system consists of certain energy hubs and interconnectors that are coordinated by energy hub system operator. an energy hub contains several converters and storages to serve demanded services in most efficient manner from available energy carriers. in this paper, the flexibility of energy delivery point is enhanced u...

this paper concentrates on a new procedure which experimentally recognises gears and bearings faults of a typical gearbox system using a least square support vector machine (lssvm). two wavelet selection criteria maximum energy to shannon entropy ratio and maximum relative wavelet energy are used and compared to select an appropriate wavelet for feature extraction. the fault diagnosis method co...
