System modeling based on short samplings and global interaction
Francesco Muzi · International Conference on Circuits · 2008
In recent years instruments used to dialog with both the physical and social world have become faster and more accurate, even able to reproduce experiments. The possibility to record detected data and to exchange information have greatly increased, revolutionizing the laws and models used by man to interpret physical nature. At the same time, mathematical tools other than differential calculus, based on the theory of numbers have been used, since in nature anything is continuous, which means that the use of averaged quantities limits the system investigation. In the engineering science this change and its profound consequences cannot be ignored, and in electrical engineering the presently available mathematical tools have to be applied to non-homogeneous materials. Non-homogeneity affects a number of electrical and electronic fields, such as structures, magnetic dominions, iron-electric materials, biological effects of electromagnetic fields, etc. The development of instrumentation and processing techniques able to extract parameters useful to describe the different phenomena are widely discussed.
