The state of innovation in modeling and simulation: The last 50 years
نویسندگان
چکیده
Innovation in Modeling and Simulation (M&S) refers to exploiting new ideas, exploiting new technology, and employing out-of-the-box thinking, which lead to the creation of new methodologies, techniques, concepts, frameworks, and software. This paper addresses the following questions: (a) what was the state of the art in M&S 50 years ago, what is it today, how much progress has been made? (b) how much innovation in M&S has been accomplished over the last half a century? (c) what were the obstacles to innovation in M&S? (d) what are some recommendations to promote innovation in M&S? (e) what message should be sent to the funding agencies to encourage innovation in M&S?

متن کاملEvaluation of Dynamic Probing Testing Effect in Hand Excavated Pit on Test Results Using Numerical Modeling
In Iran, using the hand excavated pits (wells) have been more common compared to other countries. As a matter of fact, recent years, utilizing the dynamic probing test (DPT) in these types of pits has been significantly developed in Iran. This is while the standard state of doing this test is from the ground level. In this work, the dynamic probing test is carried out in two similar wells with ...
