1. Introduction A conceptual framework is required for understanding the relative merits and utility of alternate computer systems for high performance: their architecture, execution model, and software methods for programming and operation. The general concept of " productivity " has been articulated as that attribute of the entire process of computing that delivers ultimate value to the end u...

In this work, a new drilling and blasting design methodology is introduced and applied at a case study mine to improve productivity. For the case study copper mine, a blast diameter of 203 mm is proposed to be used in the ore zone to meet the new required production rate of 90mtpa from 75mtpa. Currently, the Konya and Walter’s model is used to generate drilling and blasting design at a bl...

It is possible to eliminate some of the traditional problems with GIS implementation by changing the model of space used. The Voronoi spatial model has bee used as the basis of a set of core GIS or spatial operations, with encouraging results. It has been implemented in a PC environment so as to leave as much flexibility as possible for the designer of any particular application. Examples inclu...

Agroforestry, the deliberate integration of trees into crop and livestock operations, has the potential to achieve many of the environmental, economic, and social objectives being demanded from working landscapes by landowners and society. To simultaneously address these diverse landowner and societal goals, a multi-scale planning process must be utilized. This planning process can be expedited...

The overall aim of this paper is to explore the potential application of Geographic Information System (GIS) technology in forest management in general and in 3 African countries. The use of GIS has flooded almost every field in the engineering, natural and social sciences, offering accurate, efficient, reproducible methods for collecting, viewing and analyzing spatial data. According to Upadhy...

A distributed system for monitoring and forecasting of the marine environment is being developed in line with INSPIRE and GMES recommendations for a Spatial Data Infrastructure (SDI) architecture. This system, DISPRO, enables integration and distribution of multi-source data from satellites, aircrafts and in situ instruments, as well as results from numerical models. Geographic data and metadat...
