A Russell Measure for Modeling Environmental Performance
Data Envelopment Analysis (DEA) has been long employed as a popular methodology to evaluate the performance of various production activities with multiple inputs and outputs. However, an important issue is that the production process in the real world inevitably generates undesirable outputs (like wastes and pollutants) along with desirable outputs. Therefore, the undesirable outputs should be ...
متن کاملA review on neutron shielding performance of nano-composite materials
Neutron sources employed in different applications in both medicine and industry. Due to the harmful effects of neutron particles on living organisms, radiation shields have played a vital role in radiation protection against neutrons. In recent decade, numerous investigations conducted on the design and fabrication of nanocomposites as more efficient shielding materials against fast and therma...
متن کاملHardness estimation of complex oxide materials
Hardness is too complex to be described by first principles. Based on the dielectric chemical bond theory, a semiempirical approach for the evaluation of the hardness of ionic oxide crystals has been proposed. It was applied to predict the hardness of complex crystals such as the optical crystals yttrium aluminum garnet, the LaMgAl11O19 aluminates, and the high-Tc superconductor YBa2Cu3O7. The ...
متن کاملSupplemental Materials Appendix a Hardness of Problem 2
In this appendix, we discuss the hardness of Problem 2 presented in Section 4.2. Specifically, we discuss the nonlinearity and non-convexity of the problem. We note that non-linear and non-convex optimization problems often have exponential complexities and the general solution to them does not exist [1]. In the constraint of Problem 2, the detection probability PDj , which is given by (3), has...
متن کاملPractical Search Index as a Hardness Measure for Genetic Algorithms
Use of the Building Block Hypothesis to illuminate GA search behavior, as pursued by J. H. Holland and D. E. Goldberg, invites additional investigation.This paper investigates the space actually searched by a GA, in light of the Building Block Hypothesis, GA sampling and population size, in an effort to develop more quantitative measures of GA hardness for problems where building block sizes ca...
