We propose a method to measure the energy distribution of low-energy flares (nanoflares) in range below 1023 erg. As an example, we measured spectrum nanoflares 1021–1026 erg for two Sun’s frames observed by SDO/AIA telescope 171 Å channel. Nanoflares are shown have power law 1022–1026 range. The spectral index is approximately constant, i.e. energy-independent. For energies 1022 erg, begins co...

this paper proposes a flexible power electronic transformer (fpet) for the application in the micro-grids. the low frequency transformer is usually used at the point of common coupling (pcc) to connect the low voltage grid and utility network to each other. the conventional 50hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. in this pap...

Skew is one of the most important parameter that decides the performance of the system. Though skews are reduced using two-stage(low and high voltage levels) serially connected power mode aware buffers(PMABs) using two power gating techniques-Fine grain technique at high voltage level and Coarse grain technique at low voltage level, the power consumption and area is large incase of fine grain t...

The methods of building a model like Markov chain Monte-Carlo (MCMC) and sequential model-based global optimization (SMBO) in power distribution network (PDN) have achieved parameter identification successfully without extra measurement devices. However, the data processing focused on feeder is not concerned yet. In this study, authors present dynamic prepossessing method for PDN to obtain more...
