Approximate dynamic analysis of structures is achieved by fast wavelet transform (FWT). The loads are considered as time history earthquake loads. To reduce the computational work, FWT is used by which the number of points in the earthquake record are reduced. For this purpose, the theory of wavelets together with filter banks are used. The low and high pass filters are used for the decompositi...

introduction: seizures are symptoms associated with abnormal electrical activity in electroencephalogram (eeg). the present study was designed to determine the effect of absence seizure on heart rate (hr) changes in electrocardiogram (ecg). methods: hr alterations were recorded simultaneous with spike and wave discharges (swd) by eeg in 6 wag/rij rats as a well characterized and validated genet...

Discrete nonorthogonal wavelet transforms play an important role in signal processing by offering finer resolution in time and scale than their orthogonal counterparts. The standard inversion procedure for such transforms is a finite expansion in terms of the analyzing wavelet. While this approximation works quite well for many signals, it fails to achieve good accuracy or requires an excessive...

An algebraic theory for regular data mappings of multidimensional meshes is introduced. Mappings with nice algebraic properties are discussed. These include families of mesh{to{mesh permutations and reshapes of a mesh onto meshes of diierent shape, and are useful for expressing various regular algorithms such as e.g. dense matrix operations, fast Fourier{ and wavelet{transforms, convolutions an...
