Performance of an expert spectrogram reader

An Expert System for Performance

The rapid growth in size and complexity of distributed systems and the use of heterogeneous components require eeective tools to manage their resources. Expert system technology possesses the potential to manage such large and complex systems based on heuristic knowledge in near real time. This paper presents a general approach to designing an expert system for the management of performance of ...

Spectrogram Track Detection An Active Contour Algorithm

In many areas of science, near-periodic phenomena represent important information within time-series data. This thesis takes the example of the detection of non-transitory frequency components in passive sonar data, a problem which finds many applications. This problem is typically transformed into the pattern recognition domain by representing the time-series data as a spectrogram, in which sl...

Probabilistic DCS: An RFID reader-to-reader anti-collision protocol

The wide adoption of Radio Frequency Identification (RFID) for applications requiring a large number of tags and readers makes critical the reader-to-reader collision problem. Various anticollision protocols have been proposed, but the majority require considerable additional resources and costs. Distributed Color System (DCS) is a state-of-the-art protocol based on time division, without notew...

Dynamical spectrogram, an aid for the deaf

Visual perception of speech through spectrogram reading has long been a subject of research, as an aid for the deaf or hearing impaired. Attributing the lack of success in this type of visual aids mainly to the static form of information presented by the spectrograms, this paper proposes a system of dynamic visualisation for speech sounds. This system samples a high resolved, auditorybased spec...
