We introduce a neural network, known as SONNETMAP, capable of automatic segmentation, learning and retrieval of melodies. SONNET-MAP is a synthesis of the SONNET (Self-Organizing Neural NETwork) architecture (Nigrin, 1993) and an associative map derived from ARTMAP (Carpenter, Grossberg, and Reynolds, 1991). SONNET-MAP automatically segments a melody based on pitch and rhythmic grouping cues. S...

We present in this paper a unit testing framework for network configurations which verifies that the configuration meets prior defined requirements of the networks behavior. This framework increases the trust in the correctness, security and reliability of a networks configuration. Our testing framework is based on a behavioral simulation approach as it is used in hardware design [HM01]. The un...

A method to improve the directivity of the microstrip coupler is presented. The width of the coupler is modified for phase velocity compensation which results in high directivity. Using this procedure, a 15 dB coupler is designed and simulated at 0.9 GHz using SONNET software. A high directivity of 46 dB is obtained. The validity of the design concept is verified and compared with conventional ...
