The present article derives the minimal number N of observations needed to approximate a Bayesian posterior distribution by Gaussian. derivation is based on an invariance requirement for likelihood . This defined Lie group that leaves src=image/13422860_01.gif> unchanged, when applied both observation(s) src=image/13422860_05.gif> and parameter src=image/13422860_...

In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...

This paper investigates the reliability of an isolated buck-boost DC-DC converter (IBBC) based on configuration a series resonant (SRC). Two approaches are employed to predict IBBC reliability, which MIL-HDBK-217F handbook and FIDES guide. The latter approach can take into account how failure rate components physics is influenced by varying yearly mission profile. To do this, thermal loading ea...

This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller.  Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...

In this manuscript, the experimental setup was designed and fabricated for optimizing the parameters of a catalytic converter of INDICA V2 exhaust system. Three turbulence intensify devices, namely Swirl Venturi, Swirl Blades and Swirl Contour, were close-fitted before the catalytic converter. The heating element is embedded in its body and thermocouples are used for knowing the performance at ...

This paper presents two new analytical equations, the Two Exponent Phenomenological Percolation Equation (TEPPE) and Single (SEPPE) which, for proper choice of parameters, approximate widely used Heaviside Step Function. The plots equations presented in figures this show some, but by no means all, step, ramp, delta, differentiable activation functions that can be obtained using percolation equa...

This paper presents the analysin ,design and implementation of a high voltage ratio topology of DC-DC converter. The DC-DC converter has high voltage ratio with reduced input current, output voltage and output current ripple, and also reduces the voltage and current rating of power electronics components and compared with conventional boost converter. The voltage stress on the switches are  red...

SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...

Coronavirus infection is nowadays a major public health issue which affected societies and economics worldwide. It is therefore necessary to attempt to conduct research to find how the disease affect the human health. In this regard, the Student Research Committees (SRC), subdivision of research vice-chancellor of Iranian Universities of medical sciences have effectively contributed to provide ...
