ارایه روشی ترکیبی نوین بر اساس نسل دوم تبدیل موجک و روش جابجایی فرکانس ساندیا برای تشخیص کارکرد جزیره ای در تولیدات پراکنده مبتنی بر اینورتر

This paper is introducing a new controlling scheme with second generation wavelet transform and sandia frequency shift (SFS) for islanding detection of inverter-based distributed generation. This new hybrid method combines two active and passive methods through two performance zones. The new hybrid method calculates energy entropy of wavelet coefficients in its passive zone and if it increases ...

Haar Wavelet Collocation Method for Thermal Analysis of Porous Fin with Temperature-dependent Thermal Conductivity and Internal Heat Generation

In this study, the thermal performance analysis of porous fin with temperature-dependent thermal conductivity and internal heat generation is carried out using Haar wavelet collocation method. The effects of various parameters on the thermal characteristics of the porous fin are investigated. It is found that as the porosity increases, the rate of heat transfer from the fin increases and the th...

Stabilised wavelet transforms for non-equispaced data smoothing

This paper discusses wavelet thresholding in smoothing from non-equispaced, noisy data in one dimension. To deal with the irregularity of the grid we use so called second generation wavelets, based on the lifting scheme. The lifting scheme itself leads to a gridadaptive wavelet transform. We explain that a good numerical condition is an absolute requisite for successful thresholding. If this co...

The Lifting Scheme: a Construction of Second Generation Wavelets

We present the lifting scheme, a simple construction of second generation wavelets; these are wavelets that are not necessarily translates and dilates of one fixed function. Such wavelets can be adapted to intervals, domains, surfaces, weights, and irregular samples. We show how the lifting scheme leads to a faster, in-place calculation of the wavelet transform. Several examples are included.
