an investigation about the appropriate stochastic modeling framework for agricultural insurance pricing
با توجه به اینکه بیمه محصولات کشاورزی در ایران بیشتر جنبه ای حمایتی دارد و خسارات گزارش شده عموما بیش از حق بیمه های دریافت شده است، در این پایان نامه به جهت تعیین قیمت بیمه محصولات کشاورزی (گندم دیم) از فرآیندهای نوفه شلیک به عنوان مدلی مناسب استفاده شده است. بر اساس داده های صندوق بیمه کشاورزی از خسارات اعلام شده در سال زراعی 1388-1389 گندم دیم، در این پایان نامه حق بیمه خالص و ناخالص این محص...
Nonlinearity Characterization and Entropy Analysis of Intracardiac Atrial Electrogram Signals
The main objective of this paper is to identify evidences of nonlinear components in persistent atrial fibrillation electrograms (persAF). Firstly, an exploratory data analysis using linear approaches (autocorrelation and spectral analysis) was performed to assess the behaviour of the AF electrograms. Secondly, a nonlinear characterization using surrogate data analysis was performed with a comp...
متن کاملThe intracardiac electrogram as an aid in cardiac catheterization.
Electrocardiograms have been recorded by unipolar leads from the great veins and cavities of the right heart during cardiac catheterization in 30 of 130 cases of congenital and rheumatic heart disease. These intracardiac electrograms have given information that has proved useful in diagnosis. Further, continuous monitoring on an oscilloscope of these tracings, rather than of records from surfac...
متن کاملIntracardiac electrogram transformation. Morphometric implications for implantable devices.
Over 75,000 antitachycardia devices (ATDs) have been implanted since initial Food and Drug Adrninistra-tion approval in 1985 and have yielded dramatic survival rates. These devices, although life-saving, rely principally on simple measures of the heart rate for arrhythmia detection. The ATDs are highly sensitive, but their low specificity of diagnosis results in episodes of inappropriate therap...
متن کاملDouble-counting of intracardiac electrogram during biatrial pacing.
BACKGROUND Biatrial pacing has a significant problem with memory function that misinterprets normal sinus rhythm as atrial tachyarrhythmias and in addition estimation of the atrial pacing thresholds (biatrial and uniatrial pacing thresholds) is sometimes difficult because of small P waves. METHODS AND RESULTS The intracardiac electrograms recorded by a pacemaker in 10 patients (age, 66.7+/-10...
