Introduction: A composite index (or simply an index) is constructed with an objective to obtain a synoptic or comprehensive single number, representing a vast array of measurements on the multiple aspects of a ‘conceptual entity’ such as general price level, cost of living, level of economic development and regional disparities (Adelman and Morris, 1967; Pal, 1975; Mishra and Chopra, 1978; Mish...
In this article, the authors investigate the diverse dimensions of a knowledge society. First, the relevant literature on post industrial societies is reviewed to identify the key constituents of successful growth and development. The authors then propose a 10-dimension framework within political, economic, social and technological parameters that describe the state of evolution of a given know...
We present optical features characteristic of the shape of composite dust particles, such as grain-aggregates formed under cosmic or atmospheric conditions. The discussion develops along two examples of realistic models for the formation of the composite particles, and constant refractive indices. That way, particular features exhibited in the optical cross section behaviors result from the par...
Safeguarding the energy security is an important energy policy goal of every country. Assuring sufficient and reliable resources of energy at affordable prices is the main objective of energy security. Due to such reasons as special geopolitical position, terrorist attacks and other unrest in the Middle East, securing Iran’s energy demand and increasing her natural gas exports have turned into ...
In this paper we present two composite indices of globalization. The first is based on the Kearney/Foreign Policy magazine and the second is obtained from principal component analysis. They indicate which countries have become most globalized and show how globalization has developed over time. The indices are composed of four components: economic integration, personal contact, technology and po...
We demonstrate a readily scalable print, lift, and stack approach for producing large-area, 3D photonic crystal (PC) structures and optical gratings. UV-assisted nanoimprint lithography was used to pattern grating structures composed of highly filled nanoparticle (NP) polymer composite resists with tunable refractive indices (RI). The gratings were robust and upon release from a support substra...
Most traditional objective indices don’t distinguish between a real sound and a perceived sound, and therefore, these indices have limitations in regard to the evaluation of the real effect of an algorithm under investigation on the auditory perception of a hearingimpaired person. Though several objective indices, such as perceptual evaluation of speech quality (PESQ) and composite measurements...
BACKGROUND The randomized placebo-controlled IFIGENIA-trial demonstrated that therapy with high-dose N-acetylcysteine (NAC) given for one year, added to prednisone and azathioprine, significantly ameliorates (i.e. slows down) disease progression in terms of vital capacity (VC) (+9%) and diffusing capacity (DLco) (+24%) in idiopathic pulmonary fibrosis (IPF). To better understand the clinical im...
