In this paper, photovoltaic (PV) grid-connected inverter which is the core device in PV grid-connected system has been in depth research.An improved predictive current controller has been developed by the Authors for single-phase grid-connected voltage source inverters (VSI).Based on DSP TMS320LF2407A, a 10 kW single-phase grid-connected inverter has been built in this paper.Thus is aimed at us...

In this paper, first the validity of 3-D DDA is examined by comparing its solution for dynamic block displacement with analytical solution. Displacement of a single block on an inclined plane subjected to a dynamic loading is studied for analytical solution with respect to the frictional resistance offered by the inclined slope. 3-D DDA predicts accurately the analytical displacements. The modi...

ellis-van creveld syndrome is transmitted as an autosomal recessive trait. this syndrome is accompanied in 60% of cases with congenital heart disease, mostly single atrium or large asd. patients are mostly symptomatic, but in this rare case despite 68 years of age, the patient was free of symptoms except for complete heart block for which pacemaker was inserted

Background: Finger injuries are a common chief complaint in the emergency department (ED) and primary care setting. Repair of these injuries often require digital anesthesia through performing a digital nerve block (DNB). The two-injection subcutaneous volar block (SVB) and a two-injection dorsal digital block (DDB) are two of the most prevalently performed digital blocks in practice today. Thi...

BACKGROUND Digital nerve blocks are commonly used as effective techniques of anaesthesia to allow a variety of surgical procedures performed on digits. This study was conducted to compare the efficacy of volar subcutaneous single injection block and the traditional dorsal two injections digital block. METHODS This randomized controlled trial was conducted at Plastic and Reconstructive Surgery...
