this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
We present a novel approach of shape matching and recognition of 3D objects using arti"cial potential "elds. The potential model assumes that boundary of every 3D template object of identical volume is uniformly charged. An initially small input object placed inside a template object will experience repulsive force and torque arising from the potential "eld. A better match in shape between the ...
Tepeh Baluch is located in the northeast of Iran in Khorasan Razavi Province and in the west of Neyshabour Miankouh Plain. Prehistoric studies, especially the Neolithic period of this section of the Iranian Plateau have been less considered compared with the western part. Tepeh Baluch was explored during a short season in the spring and summer of 2011 under the support of Neyshabur University. ...
Shape context descriptors have been a valuable tool in shape description since their introduction. In this paper we examine the performance of shape context descriptors in the presence of noisy human silhouette data. Shape context descriptors have been shown to be robust to Gaussian noise in the task of shape matching. We implement four different configurations of shape context by altering the ...

it has been postulated that the building of the manjil and tarik dams on sefidroud river has led to the body shape variation of capoeta gracilis in up- and downstream populations due to the isolation. in this study, geometric morphometric approach was used to explore body shape variations of capoeta gracilis populations in up- and downstream manjil and tarik dams in sefidroud river from south o...
Background and Aim: Selecting the appropriate form of anterior teeth in patients without teeth is important factor in restoring the missing beauty of the patient. For this purpose, the study of natural teeth in terms of investigating the relationship between dimensions and forms and its prevalence in the Iranian community is essential. Materials and Methods: This analytic and descriptive stu...
