in this research the productivity and cost of komatsu d60 bulldozer in earth working operations of secondary forest road was studied in lolet forests, lied in one of the tajan river watersheds. the daily work elements of the machine including productive time, unproductive time, technical, operational and personal delays for 12 days and in two slopes of 30 to 50 and 50 to 70 percents were invest...

This communication presents some elements which come from the experience feedback at CEA about the conditions for the successful integration of HOF in the nuclear safety analysis. To point out some of these conditions, one of the concepts proposed by Edgar Morin to describe the functioning of "complex" systems: the dialogical principle has been used. The idea is to look for some dialogical pair...

Supporting group awareness is vital for the success of real-time, distributed, collaborative writing systems. Many awareness mechanisms have been introduced, but highly effective solutions are few. The research presented in this paper focuses on the development of awareness mechanisms using an experimental study of synchronous distributed collaborative writing. Our study has made two major cont...

One field in the wide area of simulation applications is the field of manufacturing systems. Within it the human factor is of growing interest. To increase the efficiency and productivity of a company besides investment in new technologies the introduction of alternative working structures becomes more and more important. For the modeling of working structures the modeling of workers is signifi...

The decision-making process is marked by two kinds of elements: organizational and technical. The organizational elements are those related to companies’ day-to-day functioning, where decisions must be made and aligned with the companies’ strategy. The technical elements include the toolset used to aid the decision making process such as information systems, data repositories, formal modeling, ...

In this work, we aim to identify the mineralization areas for the next exploration phases. Thus, the probabilistic clustering algorithms due to the use of appropriate measures, the possibility of working with datasets with missing values, and the lack of trapping in local optimal are used to determine the multi-element geochemical anomalies. Four probabilistic clustering algorithms, namely PHC,...
