We propose a wavelet based regression function estimator for the estimation of the regression function for a sequence of ?-missing random variables with a common one-dimensional probability density function. Some asymptotic properties of the proposed estimator based on block thresholding are investigated. It is found that the estimators achieve optimal minimax convergence rates over large class...
Many detection methods have been applied to detect radon gas. Due to the low noise and high resolution of gas detectors compared to semiconductor detectors or scintillation detectors, using them to detect alpha radiation is very considerable. Microstrip proportional detector is also included in this group and it has not been used for the detection of radon. In this article, response of the micr...
روش های متعددی برای جداسازی این نوع امولسیون ها وجود دارد، تکنیک انعقاد الکتریکی یکی از روش ها برای حذف روغن از امولسیون است. از این تکنولوژی برای تصفیه پساب های روغنی صنایع پتروشیمی و پالایشگاهی و جداسازی آب و نمک موجود در نفت خام استفاده شده است. هدف از انجام این آزمایشات جداسازی بنزن از امولسیون بنزن در آب با استفاده از میدان الکتریکی غیر یکنواخت بوده است. بدین منظور از یک ظرف جداساز 3 جداره...
OBJECTIVE To compare the effectiveness of paracervical block, intrauterine lidocaine and oral etodolac in decreasing the pain caused by pipelle endometrial sampling. A secondary goal of this study was to determine the adverse effects and compare possible effects of these methods on pulse and blood pressure. MATERIAL AND METHODS The study was performed between April 2006 and October 2006 in th...
This paper explores how pulse-diverse modulation of an FSK-PSK modulated pulse train enhances exibility to shape the size and distribution of the pulse train's ambiguity volume on the Doppler-delay plane. Pulse-diverse modulation compresses each pulse in the pulse train di erently. Based on a priori information of the relative criticality of various Doppler-delay regions, (e.g., the presence of...
