abstract this study was conducted under cold climate condition in khorasan during 2006-2008 growing seasons to evaluation of soil fertility in wheat-based double cropping systems under different rate of nitrogen and return of crop residues. a randomized complete block design with split-split plot arrangement and three replicates was used. main plots were five crop rotations namely: wheat-wheat,...

Time changes of return, inefficiency studies performed and presence of effective factors on share return rate are caused development modern and intelligent methods in estimation and evaluation of share return in stock companies. Aim of this research is prediction of return using financial variables with artificial neural network approach. Therefore, the statistical population of this study incl...

for assessment of portfolio performance, it's crucial to adjust the return by the risk which is taken. so it seems undeniable that for measuring the risk-adjusted return of portfolio, we need an appropriate and developed model for risk and asset pricing. fama & french 3 factor model could explain several return anomalies. recent studies show that capital productivity effects on stock retur...

Objective: The aims of the present study was to develop and validate a quick repetition test using familiar, culture-based words for the assessment of the Farsi speaking children suffering from Speech Sound Disorders (SSD). Method: The study population was divided into two groups, including 419 participants without any clinical signs of speech impairment and 36 cases with SSD. Psychometric pro...

This paper provides a comparison of three looping operations: Kleene’s repetition (‘star’), Elgot’s iteration (‘dagger’) and feedback (‘up arrow’). The comparison is based on an algebraic study of an algebra for flowgraphs (this is a generic name for digraph models like: automata, nets, flowchart schemes, etc.), called biflow. Equivalent presentations of biflows and biflows over algebraic or ma...

Many phenomena exhibit great regularity without being periodic. This is modeled using the notion of \pseudo-periodic" functions and the related \ -norm", which allow complex repetitive phenomena to be represented as a periodic process plus a set of parameters that de ne the deviations of the process from true periodicity. Applications to sunspot data and to heartbeat analysis explore practical ...

Price return and P/E are two important factors for a lot of investors based on the latest studies by researchers in Tehran Stock market; however, it is expected that the price and the variation of that affect the return and the P/E of any given market as a complicated system. The Bohmian quantum mechanics used referring to the time correlation of return and P/E of the stock market under conside...
