Data warehouses are overwhelmingly built through a bottom-up process, which starts with the identification of sources, continues with the extraction and transformation of data from these sources, and then loads the data into a set of data marts according to desired multidimensional relational schemas. End user business intelligence tools are added on top of the materialized multidimensional sch...

The long term goal attaining of economic system management requires the establishment of a dynamic framework to integrate multiple perspectives. This article considers the problem of economic development in macro level. As economic systems are complex adaptive systems composed of numerous numbers of components of dynamic and multidimensional nature, dynamics method is applied in this research. ...

Abstract We derive a priori error estimates of the Godunov method for multidimensional compressible Euler system gas dynamics. To this end we apply relative energy principle and estimate distance between numerical solution strong solution. This yields also $$L^2$$ L 2 -...
