Doubly-fed induction generator (DFIG) based wind turbines with traditional maximum power point tracking (MPPT) control provide no inertia response under system frequency events. Recently, the DFIG wind turbines have been equipped with virtual inertia controller (VIC) for supporting power system frequency stability. However, the conventional VICs with fixed gain have negative effects on inter-ar...

This paper presents an integrated CMOS compatible gas identification system for use with any type of metal-oxide gas sensor array. The logarithmic spike generation unit translates the output from any metal oxide gas sensor array into a spike pattern. The spike sequence matching circuit then compares this spike pattern with a reference set of data performing pattern recognition. The simulation r...

This paper describes a method that automates a key step in producing run-time recon gurable designs: the identi cation and mapping of recongurable regions. In this method, two successive circuit con gurations are matched to locate the components common to them, so that recon guration time can be minimized. The circuit congurations are represented as a weighted bipartite graph, to which an e cie...
