the relationship between financial ratios and stock return has been studied in many researches and the presence of income smoothing in tehran stock exchange (tse) has been verified. because of importance of financial reports in predicting and decision making process, income smoothing would be a critical factor in this area. in this paper, the income smoothing impact on relationship between fina...

An inverter circuit which generates a output high frequency AC. A low frequency AC (LFAC) to high frequency AC (HFAC) power conversion system without a DC smoothing Capacitor filter is introduced. The operating principle of a utility frequency AC-high frequency AC power frequency conversion circuit defined as a high frequency inverter is described. This synthesized converter can be considered a...

We present an implementation of a simplified scalable architecture for the efficient realization of 3-D adaptive LUM smoother in the Field Programmable Logic Devices (FPLDs). The proposed filter architecture takes advantages of a combination of recently provided Boolean LUM smoothers with bit-serial realization of stack filters. In order to decrease hardware requirements, we implemented a highl...

We propose a video enhancement sensor for smoothing random noise and getting wide dynamic range. The sensor has computational elements based on a column-parallel architecture. It detects motion and saturation of the stored charge on photo diode independently pixel by pixel. By operation at high frame rate, the motion adaptive sensor is able to control the suitable storage time in each pixel whi...

This paper gives a description of measurement technique which can be used in practice carrying out estimation electrical capacitance tested object with substantial stray inductance. Electrical is determined as ratio mean value discharge current to the time derivative, taken from voltage on unknown capacitance. The decreasing deleterious impact inductance accuracy measurements achieved by proper...

Edge preserving filters aim to simplify the representation of images (e.g., by reducing noise or eliminating irrelevant detail) while preserving their most significant edges. These filters are typically nonlinear and locally smooth the image structure while minimizing both blurring and over-sharpening of visually important edges. Here we present the Alternating Guided Filter (AGF) that achieves...

We present a theoretical study of the recovery of images x from noisy data y by minimizing a regularized cost-function F(x, y) = Ψ(x, y) + αΦ(x), where Ψ is a data-£delity term, Φ is a smooth regularization term and α > 0 is a parameter. Generally, Ψ is a smooth function; only a few papers make an exception. Non-smooth data-£delity terms are avoided in image processing. In spite of this, we con...

conclusions addressing and removing explainable patterns of syndromic data on meningitis is necessary to timely and accurately detection of meningitis epidemics. it was concluded that decomposition methods had better performance compared to the model based ones. background meningitis is one of the most disturbing infectious diseases due to mortality, morbidity and its ability to cause epidemic....
