A 58-year-old man was referred for catheter ablation of symptomatic persistent atrial fibrillation without structural heart disease. Informed consent and local committee approval were obtained. He underwent preprocedural cardiac computed tomography (CT) angiography after administration of intravenous contrast for evaluation of left atrium and pulmonary vein (PV) anatomy. The pericardiac course ...

El Fallah and Haddad 1] have described how distributed planning can be modeled using Recursive Petri Nets (RPN). This paper shows how an RPN model can be implemented using RTNet, an environment that supports distributed real-time interaction among computational agents with arbitrarily complex transition actions. The underlying RTNet implementation and interaction language are based on the schem...

Hygiene management is essential for rearing Campylobacter free broiler flocks. In this study, several hygiene factors (e.g., thinning, water supply, stable cloths, stable condition, stable environment, etc.) are categorized and aggregated in a developed risk priority number (RPN). This number is measuring the quality of hygiene management of a broiler farm with one single value (range: 801–4005...

A simple manifestation of the memorial processes is the so called reversed postoptokinetic nystagmus (RPN), a trace phenomenon elicited in the rabbit by prolonged (60 min) optokinetic (OK) stimulation. Electrophysiological analysis of RPN indicated that the underlying neural trace is weakened, but not suppressed by spreading depression in the cerebral cortex or superior colliculus. An asymmetry...

Predicting the failure modes effect and criticality analysis (FMECA) of a dynamic positioning (DP) system using fuzzy logic is aim this research. The identification DP systems subsystems, classification into critical less-critical levels based on Risk Priority Number (RPN) to depict main root causes in are some objectives support goal. offers details number issues, including their effects funct...

The interplay between the stochastic intensity fluctuation of Raman pump laser and cross-phase modulation (XPM) effect in transmission optical fiber leads to additional phase noise, namely, relative phase noise (RPN) of signal in multi-level modulated coherent optical communication system. Both theoretical analysis and quantitative simulation have been performed to investigate the characteristi...
