High-precision bearing estimation for active sonar with cylindrical array performed by interpolated array transformation
PublicationThe article presents a method for improving the accuracy of bearing in multibeam sonar with a cylindrical array. The antenna’s non-linear shape and the resulting non-uniform sampling of the signal in space, mean that known methods of high-resolution spectral analysis cannot be used. In order to apply an algorithm from this group, a linear virtual antenna must be produced. The paper presents a technique of mapping a cylindrical...

Architecture supporting security of agent systems
PublicationW rozprawie zaproponowano nową architekturę bezpieczeństwa wspomagającą anonimowość w systemach agentowych. Moduł I architektury zapewnia funkcjonalność protokołu ochrony przed tropieniem (ang. untraceability), z tą zaletą, że nie wprowadza ograniczeń wobec agentów samodzielnie ustalających trasę własnej wędrówki. Stanowi rdzeń architektury, który zaimplementowano jako rozszerzenie platformy agentowej JADE, udostępniane publicznie...
