In this lecture, I’d like to explain a recent finding [1] which connects the two basic methods of parameter estimation, the method of maximal likelihood and the method of generalized moments (see e.g. [2]). The two methods (along with the χ method, which I won’t discuss) are very well known and widely used in experimental physics. In a sense, the connection views the method of maximal likelihoo...
the main objective of this paper is to analysis the impact of information and communication technology (ict) on energy consumption in the mena region selected countries during the period 1995-2011. for this purpose, used the model presented by sadorsky (2012) and three indicators that measured ict: the number of internet users, the number of mobile lines and the number of telephone lines. also,...
Estimation of any probability distribution parameters is vital because imprecise and biased estimates can be misleading. In this study, we investigate a flexible power function distribution and introduced new two methods such as, probability weighted moments, and generalized probability weighted methods for its parameters. We compare their results with L-moments, trimmed L-moments by a simulati...
This study investigates the moderating effect of firm size in the relationship between corporate governance (board size, board independence and ownership concentration) and banks’ risk-taking (insolvency risk and credit risk). Secondary data (annual reports) was collected from a sample of 21 Malaysian commercial banks covering the 2005–2014 accounting period. An empirical model using pooled ord...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
tourism industry has been the fastest and the most income-generating industry in the first decade of the third millennium. it has been for many countries including some of oic member countries a source of foreign exchange and contributed into their development. in this paper, we try to test empirically whether tourism expansion has had any significant effect on economic growth of oic member cou...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
Many studies have been conducted on the relationship between education as an indicator of human capital and economic growth in our country. However, there have been a few studies regarding the simultaneous impact of health capital and education indicators on the economic growth of the provinces up to now. In this regard, the present study examined the impact of human health indicators and educa...
