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...
An Efficient Framework for Accurate Arterial Input Selection in DSC-MRI of Glioma Brain Tumors
Introduction: Automatic arterial input function (AIF) selection has an essential role in quantification of cerebral perfusion parameters. The purpose of this study is to develop an optimal automatic method for AIF determination in dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) of glioma brain tumors by using a new preprocessing method.Material and Methods: For this study, ...
متن کاملEnergy-constrained Pulse Design for Mri and Nmr
Optimizing radio frequency (rf ) pulses is of interest in both Magnetic Resonance Imaging and Nuclear Magnetic Resonance Spectroscopy. Recent research has focussed on reducing rf energy for imaging, and improving excitation profile uniformity for spectroscopy. This paper summarizes the different approaches used to date, and presents an approach using continuous optimization that utilizes second...
متن کاملSparsity-constrained Nonnegative Matrix Factorization
Hyperspectral unmixing is a crucial preprocessing step for material classification and recognition. In the last decade, nonnegative matrix factorization (NMF) and its extensions have been intensively studied to unmix hyperspectral imagery and recover the material end-members. As an important constraint for NMF, sparsity has been modeled making use of the L1 regularizer. Nonetheless, recent stud...
متن کاملAn experiment automation framework for ns-3
Recent studies have indicated that tools that automate the execution of simulation experiments can serve to enhance both the usability of network simulators and the credibility of the studies developed with them. In this poster, we present the architecture for an experiment automation framework for the ns-3 network simulator. The architecture was designed with two specific goals in mind. First,...
