Simulation of natural phenomena, such as the evaluation of temperature and air flow distribution inside a room, evaluation of material damage due to mechanical and chemical loads, are crucial in the daily life of engineers. This paper presents the Computational Phenomena Pattern, whose objective is to standardize through a computational abstraction the complex interaction of coupled natural phe...

Although many parameters were investigated about weaning and mortality in critical patients in intensive units, no studies have yet investigated predictors in prolonged mechanical ventilation (PMV) patients following successful weaning. A cohort of 142 consecutive PMV patients with successful weaning in our respiratory care center was enrolled in this study. Successful weaning is defined as a p...

Among the many advances made in intensive care therapeutics in recent years, few have rivaled the impact of mechanical ventilators. Their expanded use affects all who practice in the critical care setting. This article reviews the physiologic basis for mechanical ventilation, how ventilators are classified, the various modes, and specific indications. A basic introduction is made into ventilato...

Abstract: Genetic algorithms (GAs) are a class of evolutionary algorithms inspired by Darwinian natural selection. They are popular heuristic optimisation methods based on simulated genetic mechanisms, i.e., mutation, crossover, etc. and population dynamical processes such as reproduction, selection, etc. Over the last decade, the possibility to emulate a quantum computer (a computer using quan...

Many patients with end-stage cardiomyopathy are now being implanted with Total Artificial Hearts (TAHs). We have observed individual cases of post-operative mechanical ventilator autocycling with a flow trigger, and subsequent loss of autocycling after switching to a pressure trigger. These observations prompted us to do a retrospective review of all TAH devices placed at our institution betwee...

The paper deals with coupled electromagnetic, hydrodynamic, thermal and mechanical motion phenomena in magnetorheological fluid transducers. The common structures of those devices are presented and discussed. The governing equations of coupled phenomena are presented. The numerical implementation of the mathematical model is based on the finite element method and a step-by-step algorithm. Selec...

This paper is a commentary on the foundational significance of the CliftonBub-Halvorson theorem characterizing quantum theory in terms of three informationtheoretic constraints. I argue that: (1) a quantum theory is best understood as a theory about the possibilities and impossibilities of information transfer, as opposed to a theory about the mechanics of nonclassical waves or particles, (2) g...
