Drew Fudenberg and two referees for helpful comments.
The fact that the geometry of state space can be reconstructed from a time series of observations has led to innovative prediction and control algorithms for chaotic systems. In this article we show that state reconstruction of integrate-and-re dynamics is possible from a series of interspike intervals. In particular, a chaotic spike train generated in this way can be predicted from its history...
در این مطالعه به بررسی و تخمین پارامترها با استفاده از مدل state space در فرم arimaپرداخته می شود . سپس با استفاده از پارامترهای تخمین زده شده و روش شبیه سازی مونت کارلو به عنوان ابزاری برای افزایش دقت پیش بینی فرآیندهای تصادفی، به پیش بینی برای کوتاه مدت، میان مدت و بلند مدت برای شاخص تپیکس پرداختیم که شامل 739 داده روزانه مربوط به 1 بهمن سال 1389 تا 30 بهمن سال 1392 به عنوان درون داده و نیز ...
In this paper, the one-dimensional Gray–Markel lattice-ladder discrete filter structure is extended to two dimensions (2D). The proposed 2D circuit implementation has minimal number of unit delays. Based on this circuit implementation the corresponding 2D state space realization is derived. The matrices A, b, c and the scalar d of the 2D state space model are presented in generalized closed for...
Background: Preoperational anxiety is a challenging issue in preoperative care of patients. However, lavender aromatherapy can be useful as a nursing intervention to reduce some symptoms of the anxiety. This study aimed to determine the effect of aromatherapy on the anxiety of patients undergoing surgical reconstruction of the upper limb. Methods: In this non-randomized clinical trial, a total...
In functional magnetic resonance imaging (fMRI), the process of determining statistically significant brain activation is commonly performed in terms of voxel time series measurements after image reconstruction and magnitude-only time series formation. The image reconstruction and statistical activation processes are treated separately. In this manuscript, a framework is developed so that stati...
