Detention rockfill dams are accounted as economically efficient structures for flood control, river bed and banks protection, flow diversion, etc. As the hydraulic behavior of these structures, when are used for flood control, is affected by the depth of water in their porous media, there is interests to predict water surface profile through the body of these structures. In this research, we de...

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...

Active infrared thermography is a widely used technique in the field of nondestructive testing. The subsurface defects produce non-uniform heat dissipation and this phenomenon is captured by an infrared camera. The phase image gives a prominent description of the defects which are not visible in the captured image sequence. The effect of non-uniform heating and the variation in surface emissivi...

This research integrated a MEMS electrostatic driven micro-probe and a laser Doppler vibrometer for non-contact vibration mode scanning probe microscope system design. The microprobe tip was placed in perpendicular to the sample surface, and the built-in capacitor on the microprobe was excited to vibrate by a sinusoidal drive voltage to generate Coulomb electrostatic force. The applied frequenc...

The impact of roughness skewness (ksk) on turbulent boundary layer (TBL) flow with a zero pressure gradient over three-dimensional (3D) sinusoidal rough surfaces was experimentally investigated using single hotwire anemometer. Nine 3D profiles were manufactured positive, negative, and values. Measurements taken at three different freestream velocities for each surface compared smooth wall TBL r...

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...
