در ایران بیمه خودرو سهم بزرگی در صنعت بیمه دارد. تعیین حق بیمه مناسب و عادلانه نیازمند طبقه بندی خریداران بیمه نامه براساس خطرات احتمالی آنها است. عوامل ریسکی فراوانی می تواند بر این قیمت گذاری تاثیر بگذارد. طبقه بندی و تعیین میزان تاثیر گذاری هر عامل ریسکی بر قیمت گذاری بیمه خودرو پیچیدگی خاصی دارد. در این پایان نامه سعی در ارائه راهی جدید برای طبقه بندی عوامل ریسکی با استفاده از اصول و روش ها...
Multiresolution and Wavelets
Multiresolution is investigated on the basis of shift-invariant spaces. Given a finitely generated shift-invariant subspace S of L2(IR), let Sk be the 2-dilate of S (k ∈ ZZ). A necessary and sufficient condition is given for the sequence {Sk}k∈Z to form a multiresolution of L2(IR). A general construction of orthogonal wavelets is given, but such wavelets might not have certain desirable propert...
متن کاملWavelets and Multiresolution Processing
– Fourier transform used to analyze signals by converting signals into a continuous series of sine and cosine functions, each with a constant frequency and amplitude, and of infinite duration – Real world signals (images) have a finite duration and exhibit abrupt changes in frequency – Wavelet transform converts a signal into a series of wavelets – In theory, signals processed by wavelets can b...

متن کاملApplication of Adaptive Wavelets for Speech Coding
This paper describes a high quality, low bit rate (about 2.4 k bits per sec) speech coder which uses adaptive wavelets to model speech. The optimal wavelet parameters which correspond to the speech model that produced a particular sound are obtained using a feed forward neural network. These parameters are then quantized using scalar and Vector Quantization (VQ) techniques to reduce the number ...
