background and objective: cerebral arteriovenous malformation (cavm) hemodynamic is disease condition, results changes in the flow and pressure level in cerebral blood vessels. measuring flow and pressure without catheter intervention along the vessel is big challenge due to vessel bifurcations/complex bifurcations in arteriovenous malformation patients. the vessel geometry in cavm patients are...

an artificial neural network (ann) approach was used to model the wheat production. from an extensive data collection involving 40 farms in canterbury, new zealand, the average wheat production was estimated at 9.9 t ha-1. the final ann model developed was capable of predicting wheat production under different conditions and farming systems using direct and indirect technical factors. after exa...

zinc is the first modelling language which supports solver and technique independence. this means that a high level conceptual model can be automatically mapped into an appropriate low level design model for a specific solver or technique. to date, zinc uses three different techniques to solve a model: constraint programming (cp), local search (ls), and mixed integer programming (mip). in this ...

over the last decade or so, artificial neural networks (anns) have become one of the most promising tools formodelling hydrological processes such as rainfall runoff processes. however, the employment of a single model doesnot seem to be an appropriate approach for modelling such a complex, nonlinear, and discontinuous process thatvaries in space and time. for this reason, this study aims at de...

in recent years, artificial neural networks (anns) have become one of the most promising tools in order to model complex hydrological processes such as the rainfall-runoff process. in many studies, anns have demonstrated superior results compared to alternative methods. anns are able to map underlying relationship between input and output data without prior understanding of the process under in...

This paper argues that Levi’s account of preference reversals is only a limited success. Levisucceeds in showing that an agent acting in accord with his theory may exhibit reversals.Nevertheless, the specific account that Levi presents in order to accommodate the behaviorof experimental subjects appears to be disconfirmed by available evidence.

Dementia is an increasing problem for an aging population, with a lack of available treatment options, as well as expensive patient care. Early detection is critical to eventually postpone symptoms and to prepare health care providers and families for managing a patient’s needs. Identification of diagnostic markers may be possible with patients’ clinical records. Text portions of clinical recor...
