Better prediction of electromagnetic compatibility (EMC) for components is becoming a topical demand, due to technology improvements. It is requested by integrated circuit (IC) manufacturers as well as by equipment integrators. The French UTE standardisation group has proposed an EMC modelling methodology for ICs, called ICEM (Integrated Circuit(More)
Dynamic current activity extraction plays a very important role in estimating the electromagnetic compatibility of integrated circuits. For that purpose, the Integrated Circuit Electromagnetic Model (ICEM) is being developped by the International Electrotechnical Commission (IEC). This article introduces a mixed-mode simulation methodology, based on the(More)
Fuzzy logic has been used as a tool in structure-camphoraceous odor relationships. The data base studied included 99 molecules. The rules used to discriminate between camphor and non camphor molecules lead to 77% correct discrimination. Such rules account for the shape and the size of the molecule. Their adjustment by means of genetic algorithms led to 84%(More)
With vigorous development of the Internet, e-learning system has become more and more popular and many adaptive learning systems have been developed. In recent years, researchers have proposed various approaches for developing adaptive learning systems based on concept maps. Nevertheless, most of them deal only with binary grades of each test item,(More)
—The Chiu's method which generates a Takagi-Sugeno Fuzzy Inference System (FIS) is a method of fuzzy rules extraction. The rules output is a linear function of inputs. In addition, these rules are not explicit for the expert. In this paper, we develop a method which generates Mamdani FIS, where the rules output is fuzzy. The method proceeds in two steps:(More)
— In this paper, we present a new block budgeting algorithm which speeds up timing closure in timing driven hierarchical flows. After a brief description of the addressed flow, block budgeting challenges are detailed. Then, we explain why existing budgeting approaches are not adapted to fulfil these challenges. A new block budgeting algorithm is proposed.(More)
