excessive alveolar bone resorption is commonly found when teeth are extracted. this is a problem in anterior part of mouth because it will result in an unaesthetic pontic on a narrow hollowed out alveolar ridge. yet, another problem is gingival recession and root exposure in adjacent teeth which represent a therapeutic problem to the clinician. use of acellular dermal matrix graft is an appropr...

This paper addresses the problem of speaker-dependent isolate digits recognition using sole visual information. We employ intensity transformation and spatial filter to estimate the minimum enclosing rectangle of mouth in each frame. Thus, for each utterance, we can obtain two vectors composed of width and height of mouth, respectively. Then, we propose an approach to recognize the speech based...

[1] Glacial occupation of alpine valleys results in a distinct signature in the long-valley profile, including steepening of the profile in the headwaters, flattening at lower elevations, and a step in the profile at the convergence of headwater tributaries. We present analytic results for glacial erosion patterns by making the following assumptions: (1) the initial profile is linear, (2) the w...

during this survey 29 sites have been recognized totally. settlement patterns determined base of environmental characteristics such as altitude, ground slope, source of water, petrology and geology, vegetations, land use and specifications of sites including width, chronology, regional distribution and density and all of them have been divided by using geographic information systems (gis) and c...

Hypohidrotic ectodermal dysplasia (HED) is characterized by clinical manifestations of severe hypodontia or anodontia, hypotrichosis, hypohidrosis, and specific facial appearance. Affected males show complete expression of clinical features of this condition. Their mothers, who are gene carriers, express only some signs, which are usually very mild. Currently available clinical methods are not ...

in central part of kopeh dagh there is an array of active right-lateral strike-slip faults that obliquely cut the range and produce offsets of several kilometers in the geomorphology and geological structure. geomorphic indices indicate the presence of differential uplifting in history of this area. tectonic activity of the study area is investigated by a large number of dem derived catchments ...

A real world automatic lip reading system must be able to cope with movement of the speaker’s head during operation. The observed mouth shape depends not only on the true shape of the mouth, but also the angle at which the mouth is viewed. As the speaker’s head moves and rotates the viewing angle changes. The resulting distortion can lead to inaccurate mouth measurement and incorrect phoneme re...
