In present study, using Least Squares (LS) method, we determine the position smoothing in GPS single-frequency receiver by means of pseudo-range and carrier phase measurements. The application of pseudo-range or carrier phase measurements in GPS receiver positioning separately can lead to defects. By means of pseudo-range data, we have position with less precision and more distortion. By use of...

A grid-connected photovoltaic (GCPV) system plays an important role in the development of green technology. However, generated (PV) power that is injected into grid causes instability system. Previous studies have shown quality for a three-phase thoroughly being discussed, but not single-phase Single-phase also contribute to low-voltage networks during high penetration as majority GCPV nowadays...

multiple myeloma (mm) characterized by proliferation of plasma cells in bone marrow and production of monoclonal immunoglobulin's. recently, arsenic trioxide (ato), has been considered for treatment refractory mm. we assessed the safety and efficacy of ato for patients with refractory mm. a phase 2, study of arsenic trioxide was conducted in 12 mm patients, whose refractory to two standard ther...

cobalt ferrite nano-powder have been obtained through a hydrothermal method with 2:1 molar ratio of fe:co without using any surfactant. x-ray diffraction (xrd) and scanning electron microscopy (sem) were used to consider the structural and morphological properties of cofe2o4 nano-particles. also, edax spectroscopy applied to evaluate the chemical composition. results demonstrated that 15 hr hyd...
