Different countries, especially developing ones, have resorted since the middle of last century to using industrial policy in order expand base and push forward economic development wheel. Tangible results been achieved many Asian while no such countries Latin America Africa. Support has dropped for application mid-eighties because negative consequences resulting from it then return again recen...

Data warehouses and OLAP systems help to analyze complex multidimensional data and provide decision support. With the availability of large amounts of spatial data in recent years, several new models have been proposed to enable the integration of spatial data in data warehouses and to help analyze such data. This is often achieved by a combination of GIS and spatial analysis tools with OLAP an...

Abstract Given the industrial and commercial pursuit of efficiency, it has become urgent to enhance overall operational efficiency automated three-dimensional warehouses. This paper focuses on improving stacker in such To this end, we deduce deflection formula simulate swing identify factors that affect its stability. Based these findings, propose a new speed curve optimization control scheme p...

The industrial wireless local area network (IWLAN) is increasingly dense, not only due to the penetration of wireless applications into factories and warehouses, but also because of the rising need of redundancy for robust wireless coverage. Instead of powering on all the nodes with the maximal transmit power, it becomes an unavoidable challenge to control the transmit power of all wireless nod...

Many data warehouses contain massive amounts of data and grow rapidly. Examples include warehouses with retail sales data capturing customer behavior and warehouses with click-stream data capturing user behavior on web sites. The sheer size of these warehouses makes them increasingly hard to manage and query efficiently. As time passes, old, detailed data in the warehouses tend to become less i...

The maintenance of data warehouses is becoming an increasingly important topic due to the growing use, derivation and integration of digital information. Most previous work has dealt with one centralized data warehouse (DW) only. In this paper, we now focus on environments with multiple data warehouses that are possibly derived from other data warehouses. In such a large-scale environment, data...

An approach for organizing the information in the data warehouses is presented in the paper. The possibilities of the numbered information spaces for building data warehouses are discussed. An application is outlined in the paper.
