In the present work, (Cu-Sn, Cu-Co) based alloys with different compositions have been obtained by using powder metallurgy (PM). These alloys were created with the purpose of increasing mechanical and structural properties of the industrial parts. The compacts are made according to the sintering manufacturing method, the uniaxial compressed cold samples. Metallographic characterizations, hardness and density measurements were carried out in order to study the influence of the addition of tin and cobalt, the variation of the compaction pressure and the sintering temperature on the finishing product. It has been proved that the addition of tin and cobalt to a copper powder mixture increase the properties of the sintered parts.

In this paper, we reviewed business intelligence in scientific research aspect, its existing tools on the market; its situation in the world and its situation in Algeria. We then analyzed the situation of the business intelligence at SCIMAT company which is our case study. We proposed a moderated monitoring system in management of alerts and monitoring of web pages, management of external events or internal to the production systems (training, conferences...etc.) and its most consistent module; a configurable and customizable survey generator (which we have called STL 1.0) into categories of questions, types of questions, the choice of languages to allow the members of the sample, to better understand the questions and to answer them correctly, come later the statistical calculations which are on several parts; as a positive response rate tables questions, accompanied by charts.We have applied this tool to generate several e-questionnaires or e-surveys that make it possible to make global or regional cartographies on the studied aspects.
