In organic scintillators, the energy distribution of gamma rays and neutrons is indirectly measured by the pulse height distribution of light output produced through gamma ray and neutron reactions in the detectors. Accurate estimate of the interaction of gamma and neutrons in the detector and produce charged secondary particles and subsequent scintillation light produced in the calculation of ...

The characteristics of near-fault ground motion are investigated considering heterogeneous slip distribution on the fault plane. Areas on the fault plane with large slip in compare with the average slip on the fault are known as asperity. The characteristics of strong ground motions in near-fault area are strongly affected by faulting parameters such as asperity location, maximum slip of asperi...

The basolateral amygdala (BLA) has substantial effects on the neuronal transmission and synaptic plasticity processes through the dentate gyrus. Orexin neuropeptides play different roles in the sleep/wakefulness cycle, feeding, learning, and memory. The present study was conducted to investigate the function of the orexin receptors of the BLA in the hippocampal local interneuron circuits. For t...

Abstract. In this paper, we implement numerical solution of differential equations of frac- tional order based on hybrid functions consisting of block-pulse function and rationalized Haar functions. For this purpose, the properties of hybrid of rationalized Haar functions are presented. In addition, the operational matrix of the fractional integration is obtained and is utilized to convert compu...

Pulse compression technique combines the high energy characteristic of a longer pulse width with the high resolution characteristic of a narrower pulse width. The major aspects that are considered for a pulse compression technique are signal to sidelobe ratio (SSR), noise and Doppler shift performances. The traditional algorithms like autocorrelation function (ACF), recursive least square (RLS)...

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...

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...
