Heuristic algorithms are usually employed to find an optimal solution to NP-Complete problems. Genetic algorithms are among such algorithms and they are search algorithms based on the mechanics of natural selection and genetics. Since genetic algorithms work with a set of candidate solutions, parallelisation based on the SIMD paradigm seems to be the(More)
BACKGROUND Hypertension and type 2 diabetes mellitus (T2DM) are important causes of non-ischaemic heart failure (HF). Understanding the pathophysiology of early HF may guide screening. We hypothesised that the underlying physiology differed according to aetiology. METHODS In this cross-sectional study of 521 asymptomatic community-based subjects ≥65 years(More)
During voiced speech, the larynx provides quasi-periodic acoustic excitation of the vocal tract. In most electrolarynxes, mechanical vibrations are produced by a linear electromechanical actuator, the armature of which percusses against a metal or plastic plate at a frequency within the range of glottal excitation. In this paper, the intelligibility of(More)
This paper presents a detailed study of the vibrations on the surface of the neck during a vocalization of predefined fundamental frequency and intensity. This study was carried out as part of a wider investigation into the use of laryngeal vibrations as a channel of communication. Another potential application of this study is in identifying a suitable(More)
