In this paper, we address the estimation of the parameters of the two dimensional sinusoidal signal model. The proposed method is the two dimensional extension of the one dimensional noise space decomposition method. The proposed methods provide consistent estimators of the unknown parameters and they are non-iterative in nature. We propose a pairing algorithm also, which helps in identifying t...

ABSTRACT: Probability theory is applied to the problem of estimating the amplitudes of the sinusoids in nuclear magnetic resonance data containing two exponentially decaying sinusoids. The posterior probability-density of one of the amplitudes is derived independent of the phases, frequencies, decay-rate constants, variance of the noise, and the amplitude of the other sinusoid. This probability...

To evaluate the seismic performance of pre-cast concrete shear wall with vertical reinforcements spliced by two different grout ways, quasi-static tests of two concrete shear walls holed by prefabricated corrugated pipe and one concrete shear wall holed by drawing out the pipe were tested. The test results showed that the wall holed by prefabricated corrugated pipe was basically the same as the...

Chagas disease is a vector-borne and potentially fatal parasitic disease that is transmitted by the triatomine bug, a nocturnal feeding, flying arthropod, often referred to by its colloquial name, the "kissing bug." Vector-borne transmission is considered the most important means of spreading Chagas disease in endemic and nonendemic areas. Corrugated cardboard boxes may accelerate the spread of...

Genetic Programming has been used to determine Chèzy resistance coefficient for full circular corrugated channels. Three corrugated plastic pipes have been experimentally studied in order to generate data. The tests aim at measuring hydraulic parameters of the open-channel flow for some slopes, from 3.49–17.37% (2–10°), in order to discover the dependence of the channel resistance coefficient w...

In this study, fire resistance tests were performed on a conventional slim floor beam and a prestressed composite beam with corrugated webs, which is suitable for a long-span structure with a reduction in story height by utilizing the prestress and accordion effect. In the fire test program, the ISO 834 standard fire curve was adopted. Key test variables were the effect of prestress, shape of c...

introduction: cisplatin is an antineoplastic drug, which is widely used for the treatment of solid tumors. however, its clinical usage is limited because of its side effects such as hepatotoxicity. this study aimed to identify toxic effects of cisplatin on hepatocytes of rats. methods: a total of 45 adult sprague dawley rats weighing 200±30 g were randomly divided into experimental (n=30) and c...

This work is focused on the finite element study of the energy absorbing behavior of aluminum (corrugated webs). The aim is to study the mechanism of energy absorption in specific metallic structures by understanding these mechanisms. The sine wave web (or corrugated web) structural component constructed of aluminum has been chosen as the specific structural element for this study. The sine wav...

Introduction: The periodic moment method, developed by Munk and colleagues at Ohio State University, is one of the most important and powerful contributions to numerical analysis of antenna arrays, frequency selective surfaces and gratings. PMM, with its extensions and improvements, can handle multiple dielectric layers and slotted metallic sheets, with wires partially inside a dielectric or ai...

We experimentally observe the excitation of dark multipolar spoof localized surface plasmon resonances in a hybrid structure consisting of a corrugated metallic disk coupled with a C-shaped dipole resonator. The uncoupled corrugated metallic disk only supports a dipolar resonance in the transmission spectrum due to perfect symmetry of the structure. However, the dark multipolar spoof localized ...
