A new fuzzy maximum power point tracker (MPPT) for photovoltaic systems is proposed. Fuzzy controller input parameters dI dP , ) dI dP ( D and variation of duty cycle ( DC D ) are used to generate the optimal MPPT converter duty cycle, such that solar panel maximum power is generated under different operating conditions. A photovoltaic system including a solar panel, a fuzzy MPP tracker and...

Eight species of the family Arrhopalitidae Stach, 1956 are listed from the Republic of Moldova. A new species, Arrhopalites prutensis sp. nov. is described. It belongs to the diversus group of species with 3, 2, 1, 1 anterior setae on dens, possesses neosminthuroid seta on the furca base region-a character rarely noted for the family. The new species is closely related to A. baccettii Dallai, 1...

Objective(s): To determine the effects of triiodothyronine (T3) intracoronary perfusion in isolated hearts and short-term administration in rats on the left ventricular (LV) phosphorylation patterns of Akt and ERK1/2. Materials and Methods: Cardiodynamic and hemodynamic parameters were evaluated in Langendorff–perfused hearts. Left ventr...

An ultrafine grained dual phase (UFG DP) steel containing niobium was produced by a new route utilizing simple cold-rolling and subsequent intercritical annealing of ferrite/martensite duplex starting structures. The effects of intercritical holding time on the microstructural evolutions and mechanical properties were studied. The results showed that increasing intercritical holding time enhnac...

wind regime data from the jask meteorological station from a 20-year statistical period (1985-2005) was analyzedusing the fryberger method to investigate sand drift potential (dp) in this area. the resultant drift potential anddirectional variability of wind were calculated and illustrated. average annual sand dp was estimated to be 460vector units (vu), and the sand flux is 51 m3/m.year. there...

double pylorus (dp) is a rare condition characterized by the presence of two openings from the gastric antrum to the duodenal bulb, which may be congenital or acquired. herein, we describe a case of dp in a cirrhotic patient.
