Hearing aid fitting method based on fuzzy logic processing
PublicationWażnym etapem dopasowania współczesnych aparatów słuchowych jest wyznaczanie charakterystyki dynamiki słuchu. Charakterystyka ta wyznaczana jest na podstawie wyników testu skalowania głośności. Niestety wyniki te wyrażone są w skali kategorii głośności, natomiast aparaty słuchowe wymagają para-metrów numerycznych. Problem ten można rozwiązać za pomocą logiki rozmytej. W niniejszym referacie przedstawiono metodę przetwarzania rozmytego...

Mitigating Time-Constrained Stolen-Credentials Content Poisoning in an NDN Setting
PublicationNDN is a content-centric networking architecture using globally addressable information objects, created by publishers and cached by network nodes to be later accessed by subscribers. Content poisoning attacks consist in the substi-tution by an intruder publisher of bogus objects for genuine ones created by an honest publisher. With valid credentials stolen from an honest publisher, such attacks seem unstoppa-ble unless object...
