REDUCTION OF INVERTER OUTPUT CURRENT RIPPLE IN CONNECTION OF FUEL CELL TO THE POWER NETWORK

In this paper, a method is introduced which reduces the harmonicdistortion of the inverter output current, connecting the fuelcell to the AC load. Using FUZZY LOGIC-PI (FLPI), the controllingmethod is engaged in optimum tuning of the PI controllercoefficients of this converter. This converter has only one DC-ACboost inverter and simultaneously has the task of increasingvoltage level and generat...

Auditory Plasticity: Vocal Output Shapes Auditory Cortex

Studies in humans and songbirds have revealed a close link between vocal output and hearing. Now experiments in marmosets have shown that self-generated vocalizations can modulate the activity of neurons in the auditory cortex and even remodel their response properties.

Numerical Geometry of Non-Rigid Shapes

Scale Invariant Geometry for Nonrigid Shapes

Local scale variations within the same species are common in nature. The shape matching puzzle poses fascinating questions, like how should we measure the discrepancy between a small dog with large ears and a large one with small ears? are there similar geometric structures that are common to an elephant and a giraffe? what is the morphometric similarity between a blue whale and a dolphin? Exis...

Geometry Shapes Evolution of Early Multicellularity

Organisms have increased in complexity through a series of major evolutionary transitions, in which formerly autonomous entities become parts of a novel higher-level entity. One intriguing feature of the higher-level entity after some major transitions is a division of reproductive labor among its lower-level units in which reproduction is the sole responsibility of a subset of units. Although ...
