Wind power prediction accuracy is important for assessing the security and economy when wind power is connected to the grid, and wind speed is the key factor. This article presents a future four hours prediction scheme that combined chaos phase space reconstruction with NWP method. Historical wind speed data are reconstructed as phase space vectors, which are used as the first input part of pre...

Introduction: During the last decades, simulation of radiation therapy treatment conditions in treatment room for studying with more details in comparison with treatment planning system (TPS) is taken into consideration. The most problem with starting these kind of researches is the geometry of Medical linacs and verification of the accelerators. Therefore, researchers tried to...

Our proposed method of random phase-free holography using virtual convergence light can obtain large reconstructed images exceeding the size of the hologram, without the assistance of random phase. The reconstructed images have low-speckle noise in the amplitude and phase-only holograms (kinoforms); however, in low-resolution holograms, we obtain a degraded image quality compared to the origina...

here, the concept of quantum potential that has been illustrated in extended phase space (eps) in previous works is explored for its marginal behavior. unlike in configuration space, different representations of the quantum mechanics can be found in eps when exploiting appropriate canonical transformations. these canonical transformations revealed that there exist several representations in whi...

In this letter we assert that we have reconstructed the nonlinear filter function of LILI-128 stream cipher on IBM notebook PC using MATLAB. Our reconstruction need approximately 13 12 2 ~ 2 bits and the attack consumes 5825.016 sec (using tic and toc sentences of MATLAB) or 5825.016/3600=1.6181hours. We got the expression of the nonlinear filter function of Lili-128 which has 46 items from lin...

The HIPSE (heavy-ion phase-space exploration) model, by Lacroix et al., has been used to examine nucleon transfer during the interaction of the projectile and target [1]. The results of the HIPSE model were compared to experimental data obtained on the FAUST array (Forward Array Using Silicon Technology) for F + Ag, F + Au, Na + Au, and Ne + Au at 32 MeV/u [2]. The apparent mass change of the p...

Isometric feature mapping (ISOMAP) is a nonlinear dimensionality reduction method used for extracting features from spatiotemporal data. The traditional principal component analysis (PCA), linear method, measures the distance between two data points based on Euclidean (line segment), which cannot reflect actual in space. By contrast, ISOMAP geodesic distance, more closely reflects by view of tr...

Tissue tagging can be implemented during cardiovascular magnetic resonance imaging exams to assist with the quantification of left ventriculargeometry, volume and ejection fraction, endocardial thickening and relaxation, and myocardial stress-strain relationships. During tagged cine gradient echo image acquisitions of left ventricular wall motion, rows of k-space data can be acquired with vario...

Initial studies in five conscious dogs with their baroreceptors either intact or surgically isolated, demonstrate that deterministic chaos is likely to exist in both heart interval and mean arterial blood pressure. The nature of this chaotic activity is not qualitatively different between the intact and open loop preparations. To assess nonlinear dynamical behavior, we constructed phase space t...
