The starting point of this paper is the fact that the one thing that is certain about the future is its uncertainty. While uncertainty has always been a constant of human life, the paper argues that due to technological and social developments, risk and uncertainty are going to be defining features that companies of the future will have to deal with. Given that almost all managerial and organis...
Acoustic velocities of brucite were measured at room pressure in over 48 directions from Brillouin spectroscopy using a natural sample. These data are supplemented with volume measurements as a function of pressure and temperature that range from ambient conditions to 11 GPa and 873 K using synchrotron X-ray radiation at the National Synchrotron Light Source (NSLS) in a cubic-anvil apparatus (S...
در صنعت اسپینترونیک به ترکیبات دوتایی عناصر واسطه مانند بلور CrAs در فاز شبه پایدار بلندروی، به علت رفتار فرومغناطیسی نیم فلزی آن ها، توجه زیاد شده است. در این مقاله خواص انبوهه CrAs در دو فاز شش گوشیNiAs و بلندروی مورد بررسی قرار گرفته است. محاسبات با استفاده از بسته محاسباتی Espresso بر مبنای نظریه ی تابعی چگالی و نظریه ی تابعی چگالی اختلالی، با تقریب شیب تعمیم یافته (GGA) انجام شده است. نتای...
The mechanical properties including elastic stiffness constants as well as bulk modulus of Palladium (Pd) nanowire were calculated in the constant temperature and pressure (NPT), ensemble by molecular dynamics (MD) simulation technique. The quantum Sutton-Chen (Q-SC) many-body potential was used to calculate the cohesive energy as well as forces experience by every atoms. The temperature and pr...
We measured the elastic constants (C11 − C12)/2 and C44 of non-Kramers system Y0.63Pr0.37Ir2Zn20 (Pr-37% system) by means ultrasound to check how single-site quadrupolar Kondo effect is modified increasing Pr concentration. The Curie-like softening present Pr-37% on cooling from 5 1 K can be reproduced a multipolar susceptibility calculation based Γ3 doublet crystalline-electric-field ground st...
We propose a new MCDM method based on fuzzy pair-wise comparisons and a feedback between the criteria. The evaluation of the weights of criteria, the variants as well as the feedback between the criteria is based on the data given in pair-wise comparison matrices. Extended arithmetic operations with fuzzy numbers are used as well as ordering fuzzy relations to compare fuzzy outcomes. An illustr...
Many papers have regressed non-parametric estimates of productive efficiency on environmental variables in two-stage procedures to account for exogenous factors that might affect firms’ performance. None of these have described a coherent data-generating process (DGP). Moreover, conventional approaches to inference employed in these papers are invalid due to complicated, unknown serial correlat...
This paper analyzes strategic choice in p-beauty contests. First, I show that it is not generally a best reply to guess the expected target value, even in games with n > 2 players, and that iterated best response sequences strictly applied do not induce a choice sequence approximating pk · 0.5. Second, I argue that the beliefs and actions of players typically considered to be level 2–4 are capt...
Randomization adds beneficial flexibility to the construction of optimal simple plans in dynamic environments. A decision-maker, restricted to the use of simple plans, may find a stochastic plan that strictly outperforms all deterministic ones. This is true even in noninteractive deterministic environments where the decision-maker’s choices have no influence on his signals nor on the future evo...
