We propose a new algorithm to improve computational efficiency for low rank based interpolation. The interpolation is carried out in the frequency spatial domain where each frequency slice is first transferred to the frequency-patches domain. A nice feature of this domain is that the number of non-zero singular values can be better related to seismic events, which favors low rank reduction. Dur...

Prevention is better than cure is not only applicable to medical domain but also equally applicable to engineering field. By analyzing the symptoms and taking appropriate corrective measures before the actual failure takes place would avoid costly cateroscopic damages. In line with this approach a fault analysis through vibration study with wavelet transforms has been attempted in this study. T...

We provide a model-free framework for studying the dynamics of state vector and its risk prices. Specifically, we derive frequency domain decomposition unconditional asset return premium in general setting with log-affine stochastic discount factor (SDF). Importantly, show that cospectrum between returns SDF only displays dependencies through prices can be inferred from covariances (portfolio) ...

In a wind turbine, the rolling bearing is critical component. However, it has high failure rate. Therefore, analysis and fault diagnosis of power bearings are very important to ensure reliability safety equipment. this study, form corresponding reason for discussed firstly. Then, natural frequency characteristic analyzed. The Empirical Mode Decomposition (EMD) algorithm used extract characteris...

This paper describes an efficient approach to pose invariant object recognition employing pictorial recognition of image patches. A complete affine invariance is achieved by a representation which is based on a new sampling configuration in the frequency domain. Employing Singular Value Decomposition (SVD), the affine transform is decomposed into slant, tilt, swing, scale and 2D translation. Fr...

the potential energy hyper surfaces (fes) of the unimolecular rearrangements of a) nitromethane itei totrans acknitromethane b) nitrometharie (/) to methyl nitrite (3) and c) naromethane decomposition tomethyl and nitrogen dioxide were searched using the ab !nth° mp2 method. split valence 6-310(d.p) basisset was used for geometry optimizations, frequency and 1rc computations along each reaction...
