Developing spatial econometrics functions in R can not only enable analysts to advance our own techniques using convenient interpreted language features. Placing spatial econometrics and more generally spatial statistics in the context of an extensible data analysis environment also exposes similarities and differences between traditions of analysis. These can be fruitful, as is explored here i...

Estimation of ore reserves is one of the most critical aspects of mining geology. The accurate assessment of the tonnage and grade of run of mine may be the difference between a healthy profitable operation and an expensive early mine closure. The first step in ore reserve estimation is to determine the boundary of ore body or ore/waste contacts. This paper presents a specific mining applicatio...

in this article economic loss means those losses occurring independently of physical damage to things or to a person's body or health. there are two main positions about reparability of these losses: in some countries like french, belgium, spain, italy and luxembourg as a principle rule economic loss is recoverable and there is no difference between economic loss and other losses. but in s...

We discuss time evolution of some solitary waves described in the first part of this work. The adiabatic motion of the non-linear non-dispersive waves composed of three lumps is interpreted as three-body low energy scattering of these particle-like kinks.

The article considers chaos theory as a scientific concept that was developed to explain nonlinear dynamics in objects of complex nature and solve applied problems engineering, meteorology, economics, construction, etc. Application sociology provides for good outcomes big social systems. In the context management, it opens discourse models overcome “the curse complexity”. It explains transforma...

the aim of this study is 3-d inversion of magnetic data acquired from the sorkheh-dizej iron-bearing region in zanjan province, iran, in order to determine the geometrical distribution of the buried magnetic sources. for this purpose, our program discretizes the subsurface region into vertical right rectangular prisms and uses the nonlinear marquardt-levenberg algorithm to optimize the unknown ...
