This paper presents the emulation of grid-connected wind energy conversion system based on the 30 MIPS Digital Signal controller (DSC) dsPIC30f3011. This system is composed by a three-phase permanent magnet generator, an AC to DC converter and a single phase Voltage Source Inverter (VSI). The inverter was driven using Space Vector Pulse Width Modulation (SVPWM) at a switching frequency of 18 kHz and...
Drosophila Hedgehog (Hh) is secreted by Posterior (P) compartment cells and induces Anterior (A) cells to create a developmental organizer at the AP compartment border. Hh signaling converts Fused (Fu) to a hyperphosphorylated form, Fu*. We show that A border cells of wing imaginal discs contain Fu*. Unexpectedly, P cells also produce Fu*, in a Hh-dependent and Ptc-independent manner. Increasing Ptc,...
