The purpose of this paper is to investigate the levels of technical efficiency in agricultural sector of MENA countries by using Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) approaches in 2007-2008. The results show that the total average of technical efficiency is as follows: DEABCC(0.770)>DEACCR(0.744)>SFA(0.479), and among all MENA countries, the best performanc...

Recent studies in finance domain suggest that technical analysis may have merit to predictability of stock. Technical rules are widely used for market assessment and timing. For example, moving average rules are used to make "buy" or "sell" decisions at each day. In this paper, to explore the potential prediction power of technical analysis, we present a genetic programming based system FGP (Fi...

background: the rejected films in radiography may be responsible for an unnecessary increase in the radiation dose to the population. the effective dose to population is a very important factor in estimation of stochastic risk in radiology. the main goal of this study was to determine the effective dose to members of the public due to rejected films in diagnostic radiology departments in the no...

We aim to compare financial technical analysis techniques to strategies which depend on a mathematical model. In this paper, we consider the moving average indicator and an investor using a risky asset whose instantaneous rate of return changes at an unknown random time. We construct mathematical strategies. We compare their performances to technical analysis techniques when the model is misspe...

The optimal tradeoff between average service cost rate, average utility rate, and averagedelay is addressed for a state dependent M/M/1 queueing model, with controllable queue lengthdependent service rates and arrival rates. For a model with a constant arrival rate λ for all queuelengths, we obtain an asymptotic characterization of the minimum average delay, when theaverage serv...
