Additive slacks-based measure of efficiency for dealing with undesirable outputs based on DEA-R model [PDF]

open access: yesBig Data and Computing Visions, 2021
In this paper, we present an Additive Slacks-Based Measure (ASBM) model for measuring efficiency Decision-Making Unit (DMU) in the presence of undesirable outputs based on DEA Ratio based (DEA-R) model.

On the definition of signal-to-noise ratio and contrast-to-noise ratio for FMRI data. [PDF]

open access: yesPLoS ONE, 2013
Signal-to-noise ratio, the ratio between signal and noise, is a quantity that has been well established for MRI data but is still subject of ongoing debate and confusion when it comes to fMRI data.

Modifying the interconnecting activities through an adjusted dynamic DEA model: a slacks-based measure approach

open access: yesJournal of Applied Research on Industrial Engineering, 2020
A new approach to the dynamic Data Envelopment Analysis (DEA) referred to as the adjusted dynamic DEA, is proposed in this study. Adjusted dynamic DEA optimizes the production activity of DMUs by introducing adjustment variables to modify the ...

Model Checking with Right Censored Data Using Relative Belief Ratio

open access: yesEntropy, 2022
Model checking is a topic of special interest in statistics. When data are censored, the problem becomes more difficult. This paper employs the relative belief ratio and the beta-Stacy process to develop a method for model checking in the presence of ...

Proper MgO/Al2O3 Ratio in Blast-Furnace Slag: Analysis of Proper MgO/Al2O3 Ratio Based on Observed Data

open access: yesMetals, 2020
With the gradual depletion of high-quality iron-ore resources, ironmaking blast furnaces have gradually shifted to using high-content Al2O3 iron ore. Under this condition, the addition of MgO in the slag is adopted to alleviate operation problems caused ...
