In this paper we suggest an approach to describing and tracking the deformation of facial features. We concentrate on the mouth since its shape is important in detecting emotion, however we believe that our system could be extended to deal with other facial features. In our system, the mouth is described by a valley contour which is based between the lips. This contour is shown to exist indepen...

STATEMENT OF PROBLEM In complete mouth reconstructive dentistry, the occlusal vertical dimension may be increased to provide adequate restorative space or to improve esthetics. The effect of increasing the occlusal vertical dimension on the smile is not well understood. PURPOSE The purpose of this study was to evaluate the effect of increasing the occlusal vertical dimension on the dimensions...

A path to a new high performance regime has been discovered in tokamaks that could improve the attractiveness of a fusion reactor. Experiments on DIII-D using a quiescent H-mode edge have navigated a valley of improved edge peeling-ballooning stability that opens up with strong plasma shaping at high density, leading to a doubling of the edge pressure over the standard H mode with edge localize...

An understanding of the structural relationships between the soft tissue anatomy of the face and the hard tissue anatomy of the skull is significant for craniofacial identification methods employed in forensic anthropology and forensic dentistry. Typically, mouth characteristics have been predicted from the teeth but this proves problematic in edentulous skulls. Some clue may, however, be provi...

The valley oak (Quercus lobata Neé) is among the largest and longest lived of the North American oaks, attaining trunk diameters up to 4 m, heights of 12 to 25 m, and ages of 300 years or more. Unique to California, this oak is also one of California’s most familiar and evocative icons. Where they occur, large valley oaks are focal visual and ecological elements of both developed and rural land...

Result: The mean inter-alar width of the nose was 35.06 mm (37.14 mm in males and 33.21 mm in females). The mean maxillary inter-canine distance was 37.96 mm (39.66 mm in males and 36.38 mm in females). The mean mouth width was 50.66 mm (52.85 mm in males and 48.63 mm in females). The maxillary inter-canine distance was 75% of mouth width; therefore, the mouth width is a reliable predictor of t...

Landscapes have been shown to exhibit numerous scaling laws from Horton's laws to more sophisticated scaling in topography heights, river network topology and power laws in several geomorphic attributes. In this paper, we propose a different way of examining landscape organization by introducing the “river corridor width” (lateral distance from the centerline of the river to the left and right ...

There is a large controversy about the causal relations between dento-facial deformities and mouth-breathing habits. Some postural and morphological changes during long-term adaptation to oral respiration are evoked: opening of the bite with a lowered postural position of the mandible, reduction of upper arch width, downward and backward rotation of the mandible, increased lower facial height a...

This study investigates the effect of “adverse” contexts, especially that of the consonant / /, on labial parameters for French /i,y/. Five parameters were analysed: the height, width and area of lip opening, the distance between the corners of the mouth, as well as lip protrusion. Ten speakers uttered a corpus made up of isolated vowels, syllables and logatoms. A special procedure has been des...
