This paper presents the most important multilevel inverter topologies like diode-clamped inverter (neutral-point clamped), capacitor-clamped (flying capacitor), and cascaded multicell( H-Bridge ) with separate dc sources. A Comparison of 5-level hybrid cascaded inverter with PWM method, 5 level diode clamped inverter & 5 level capacitor coupled inverter is also presented in this paper. This pap...

in this paper, eringen’s nonlocal elasticity and timoshenko beam theories are implemented to analyze the bending vibration for non-uniform nano-beams.  the governing equations and the boundary conditions are derived using hamilton’s principle. a generalized differential quadrature method (gdqm) is utilized for solving the governing equations of non-uniform timoshenko nano-beam for pinned-pinned...

BACKGROUND Cord blood lactate at birth is a marker of antenatal hypoxia, and is comparable to pH as a prognostic tool. OBJECTIVE To determine, by a prospective observational study, the effect of delayed sampling from arteries and veins that were double clamped to isolate the blood from the placenta (clamped), and from vessels that were not isolated from the placenta (unclamped). METHODS Pai...

The liver forms as part of digestive system. Despite the essential functions of the liver, little is known about its early embryonic development. The clamped s819 mutant was identified in a forward genetic screen for mutations causing defects in endodermal organogenesis in zebrafish. At 44 h post-fertilisation (hpf), clamped s819 mutant embryos display liver hypoplasia and defects in extrahepat...

The contraction/relaxation responses of thoracic aortal rings clamped with two clamping pressures to potassium chloride (KC1), noradrenaline and carbachol were studied using a scanning electron microscope (SEM) to ascertain endothelial lacerations. Clamp A had the tip pressure PA = 0.60 N/mm2 and clamp B PB = 5.16 N/mm2. In 15 Wistar albino rats, weighing 328 +/- 19 g (mean +/- SD), the thoraci...
