Investigation in the deployment of a geographic information system

  After a presentation of the cereal activities in Tunisia, we present a systemic analysis of project of deployment of a geographic information system (GIS). This analysis is based on the objective oriented project planning (OOPP) method. The exploitation of the systemic analysis method enables us not only to analysis and to identify the information of the cereal activities but also to lead to an efficient...

A shift-add algorithm for computing Bezier curves

  A shift-add algorithm based on coordinate rotation digital computer algorithm for computing Bezier curves was presented in this paper. This algorithm can be implemented in basic computing system (which deals only with shift, add and logical operations) which exists in many areas. Convergence of the algorithm was proved. Error estimation was analyzed. A numerical experiment was carried out to validate...
