The objective of this work, which was conduct was to carry out the determination procedures to identify a domain by looking border (by sending appropriate signals).
We proved that if well-defined signals are sent on the known edge 永_0 of a regular field 目 of Rn (n=1, 2), where prevail some phenomena modeled by partial derivative equations and that following a certain number of ow measurements on the same edge, knowing ♁_(永_0)〤〖±u/±n gd永〗 (where n indicates the normal external of ±目), it is possible to find a method which leads to the determination of 目. The demonstration were made in the stationary case with dimension n=1, 2 and arbitrary form. |
