a fundamental assumption in prosthetic dentistry is that the axis-orbital plane will usually be parallel to the horizontal reference plane. most articulator systems have incorporated this concept into their designs and use orbitale as the anterior reference point for transferring the vertical position of the maxilla to the articulator. clinical observations of cantonese patients suggest that in...

Since Clements (1985) introduced feature geometry, four major innovations have been proposed: Unified Feature Theory, Vowel-Place Theory, Strict Locality, and Partial Spreading. We set out the problems that each innovation encounters and propose a new model of feature geometry and feature spreading that is not subject to these problems. Of the four innovations, the new model—Revised Articulator...

AIM The aim of this study was to compare the accuracy of the angle made by Frankfort horizontal plane-occlusal plane on maxillary casts, mounted using the respective facebows on Artex Amann Girrbach and Hanau Wide-vue semi-adjustable articulators with cephalometrically derived Frankfort horizontal plane-occlusal plane angle as a control. SUBJECTS AND METHODS Maxillary casts of 30 subjects wer...

291 The terminal hinge axis (THA) is the axis around which the mandible rotates when the mandible is in centric relation. The purpose of facebow is to record the patients THA and transfer it to the articulator so that it coincides with the arc of closure/hinge axis of the articulator. When the THA coincides with the hinge axis of the articulator, it is presumed that the restorations will be fre...

Neuro-physical investigations [1] hint to a new paradigm for feature extraction not used in ASR. This paradigm is based on synchronized brain to brain oscillations, active during speech production and speech perception. This mechanism leads to an evolving theory, the author calls the Unified Theory of Human Speech Processing (UTHSP). The core elements of this theory are the articulatory rhythm ...

A procedure is demonstrated for learning to recover the relative positions of simulated articulators from speech signals generated by articulatory synthesis. The algorithm learns without supervision, that is, it does not require infonnation about which articulator configurations created the acoustic infonnation in the training set. The procedure consists of vector quantizing short time windows ...

A survey of phonetics education in Europe has been carried out by the Phonetics Working Group of the Thematic Network in Human Communication Sciences. Information about the contents of current phonetics curricula across different areas of specialisation was collected from responses to a web-based questionnaire by 89 European institutes. This information was used as a point of departure in the f...
