Aortic stenosis produces a systolic murmur of characteristic shape in the phonocardiogram both in the aortic and mitral areas. Sound records were taken in 20 patients with aortic stenosis. Thq phonocardiograph used for this investigation has been described elsewhere (Leatham, 1949), and consisted of crystal microphones, valve amplifiers, and both string and mirror galvanometers. Filters were u-...

In this paper a general theory will be introduced that allows the description of a melodic surface i.e. a score-like representation of a melody in terms of local grouping, accentuation and metrical structures. Firstly, a formal model will be proposed that detects points of maximum local change that allow a listener to identify local perceptual boundaries in a melodic surface. The Local Botmdary...

Being able to predict the placement of con-trastive accent is essential for the assignment of correct accentuation patterns in spoken language generation. I discuss two approaches to the generation of contrastive accent and propose an alternative method that is feasible and computationally attractive in data-to-speech systems. 1 Motivation The placement of pitch accent plays an important role i...

forty renal allograft patients with three months under immunosuppression by cycloserine were examined for their gingival overgrowth and it's correlation with several parameters including the trough levels of blood cyclosporine and it's metabolites measured by the fluorescence polarization immunoassay technique. no correlation was found between the scores of gingival overgrowth and both the age ...
