Abstract Introduction: Acute Respiratory Distress Syndrome (ARDS) in coronavirus disease (COVID-19) is characterized by the rapid onset of acute hypoxemic respiratory failure and reduced system compliance. Conflicting results have been presented to consider static compliance pulmonary shunt levels predictors mortality. Objective: To analyze initial as a 28-day mortality parameter patients with ...

Parameters of the two-parameter logistic model are generally estimated via the expectation-maximization algorithm, which improves initial values for all parameters iteratively until convergence is reached. Effects of initial values are rarely discussed in item response theory (IRT), but initial values were recently found to affect item parameters when estimating the latent distribution with ful...

the projection strucrure is vibrated by the dynamic effects of the projectile in the inital stahes before seperation. this induces two major results, one is the calculation of stresses obtained decause of bib ration in order to design the launcher and other one which. is bery important, is the determinaion of initial condirions of the nissile prijection at the time of fron the launcher. these c...

In this work, transient dynamic stress concentration in a hybrid composite laminate subjected to a sudden internal crack is examined. It is assumed that all fibers lie in one direction and the applied load acts along direction of fibers. Two types arrangements are considered for the fiber; square and hexagonal arrangement. Using shear lag model, equilibrium equations are deduced and upon proper...

In this study, we focused on effects of finding of emergent phenomena in rule discovery. In the experiment, we used Conway’s Game of Life, which generates high-order phenomena from fundamental rules. Our research question is to realize the effects of attention to emergent phenomena on finding the fundamental rules. The two experimental conditions (chaotic and static) differed only in initial st...
