precise registering and transferring of the selected path of insertion and withdrawal of removable, partial dentures is a critical step in designing and fabricating their framework and determining the retention, stability, and support of the completed prosthesis. many authors have addressed this issue in their studies. in this study we present a new technique for registering and reproducing par...

Camera pose estimation is the problem of determining the position and orientation of an internally calibrated camera from known 3D reference points and their images. We introduce a new polynomial equation system for 4-point pose estimation and apply our symbolicnumeric method to solve it stably and efficiently. In particular, our algorithm can also recognize the points near critical configurati...

Belleville, P. and T.C. Shermer, Probing polygons minimally is hard, Computational Geometry: Theory and Applications 2 (1993) 255-265. Let r be a set of convex unimodal polygons in fixed position and orientation. We prove that the problem of determining whether k finger probes are sufficient to distinguish among the polygons in f is NP-complete for two types of finger probes. This implies that ...

The main objective of this paper is to present a method to fully determine the six degrees of freedom regarding position and orientation of a neighboring molecule around a central one, i.e. the g(rCM,ω) distribution function. This is accomplished by completely determining the short range structure of liquid carbon tetrachloride, while employing results from two different methods, Molecular Dyna...

Objectives: The purpose of this study was to compare scapular kinematics during elevation phase of abduction, flexion, and scapular plane elevation phase between fifteen persons with shoulder impingement syndrome (SIS) and thirteen persons without it. Methods: Values of scapular kinematics include scapular superior and lateral translations, upward rotation, external rotation, and posterior t...

The technique of determining the position of individual fluorescent molecules with nanometer resolution, called FIONA, has become an important tool for several biophysical applications such as studying motility mechanisms of motor proteins. The position determination is usually done by fitting a 2-D Gaussian (x-y vs. photon number) to the emission intensity distribution of the fluorescent molec...
