Zarshuran gold deposit, with the total reserves of some 12.5 million tons of 4.18 g/ton ore, is considered to be an important gold mining project in the area. In this paper the feasibility studies of the whole project is carried out on the basis of several economic variables. Given that mining...

The paper emphasizes the specific manner to perform the arithmetic operations in the computer as always it is possible to have "rounding errors". Neglecting the influence of the computer rounding errors could affect a right conclusion, for example, in the case of an account balance verification.

In a previous study, (Stefanescu, P., Stefanescu, St., 2006) we suggested two possible estimators for the unknown value of the parameter q which characterize a homographic type HG(q) distribution. In the current paper we shall prove that the proposed estimators of q based on the median of the...

In this paper, a multivariate form of truncated generalized Cauchy distribution (TGCD), which is denoted by (MVTGCD), is introduced. The joint density function, conditional density function, moment generating function and mixed moments of order <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$${b=\sum_{i=1}^{k}b_{i}}$$</EquationSource> </InlineEquation> are obtained.

This study develops a two-step estimator for a panel data Tobit model based on taking first-differences of the equation of interest, under conditional mean independence assumptions.The necessary correction terms are non-standard and a substantial part is therefore devoted to the formal...

This paper attempts to assess the adequacy of wind power generation systems using the data collected from seven wind farms in Muppandal, Tamilnadu (India) with a total capacity of 37 MW. A Monte Carlo model simulation is incorporated in the algorithm to obtain the hourly power output of wind...

We compare three alternative Maximum Likelihood Multidimensional Scaling methods for pairwise dissimilarity ratings, namely MULTISCALE, MAXSCAL, and PROSCAL in a Monte Carlo study.The three MLMDS methods recover the true con gurations very well.The recovery of the true dimensionality depends on...

In this paper we describe the use of modern numerical integration methods for making posterior inferences in composed error stochastic frontier models for panel data or individual cross-sections.Two Monte Carlo methods have been used in practical applications.We survey these two methods in some...
