Choosing funds is a general issue for investors, with the aim of balancing potential risks and returns. The this article to use super-efficiency approach analyze rank exchange-traded (ETFs) in order find best utility ETFs. range-adjusted measure (RAM)-based data envelopment analysis (DEA) model used work evaluate set ETFs inefficient funds, while RAM fully RAM-based efficient funds. Other slack...

Sediment transport in the ejector is highly stochastic and non-linear nature, its accurate estimation a complex challenging mission. This study attempts to investigate sediment removal of using newly developed hybrid data-intelligence models. The proposed models are based on hybridization adaptive neuro-fuzzy inference systems (ANFIS) with different metaheuristic algorithms, namely, particle sw...

The ultimate aim of performance evaluation is to improve the system efficiency. Overall efficiency of the system is a combination of three factors: system functionality, performance and cost. Whereas system functionality improvement and cost optimisation are usually well understood and implemented the third factor of system performance is usually under prioritized. The development and improveme...

performance evaluation of universities is an important issue between researchers. classic data envelopment analysis (dea) models with deterministic data have been used by many authors to measure efficiency of universities in different countries. however, dea with stochastic data are, rarely used to measure efficiency of universities. in this paper, input oriented model in stochastic data envelo...

Traditional data envelopment analysis (DEA) models deal with measurement of relative efficiency of decision making units (DMUs) in which multiple-inputs consumed to produce multiple-outputs. One of the drawbacks of these models is neglecting internal processes of each system, which may have intermediate products and/or independent inputs and/or outputs. In this paper some methods which are usab...

Hardware specialization is a promising direction for the future of digital computing. Reconfigurable technologies enable hardware with modest non-recurring engineering cost, but their performance and energy efficiency compared to state-of-the-art processor architectures remain an open question. In this article, we use FPGAs evaluate benefits building specialized numerical kernels found in scien...

   Measuring the performance of a production system has been an important task in management for purposes of control, planning, etc. Lord Kelvin said :“When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind.” Hence, manag...
