The identification of contact points is a priority in planning grasps. This paper proposes a criterion for the determination of optimal grip points to secure contact stability. The criterion is generally valid, that is, it applies to grasps with any number of contact points on objects having a generic shape (polygonal or curved), and does not require that the external force acting on the object...

This cross-sectional study clinically assesses the tightness of proximal contact points of fixed dental prosthesis with natural teeth. Sixty nine (69) patients visiting the Department of Prosthodontics, Armed Forces Institute of Dentists (AFID), Rawalpindi, were included. The crowns, as a single unit or terminal abutment of bridge, prepared and fabricated at the same institute were included. A ...

We study solutions for 2-1ayer models that mlffimlze the number of contact points and the effect of overlap on the channel width. All known algorithms [or the 2-1ayer model without overlap usc 8(dn) contact points. We present an algorithm Cor a restricted class of channel routing problems that uses 2d -1 tracks and D(n) contact points. While channel rouling problems of this restricted class wer...

A new method for estimating the contact point in AFM force curves, based on a local regression algorithm, is presented. The main advantage of this method is that can be easily implemented as a computer algorithm and used for a fully automatic detection of the contact points in the approach force curves on living cells. The estimated contact points have been compared to those obtained by other p...

contact mechanics is related to the deformation study of solids that meet each other at one or more points. the physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics and focuses on computations involving bodies with different characteristics in static or dynamic contact. contact mechanics gives essential information for the s...

this paper concerns the design and analysis, of a ball type continuously variable transmission, (b-cvt). this b-cvt has a simple kinematic structure, and same as a toroidal cvt, transmits power by friction on the contact points between input and output discs, that are connected to each other by balls. after, a brief introduction of our b-cvt structure, the performance and traction efficiency of...
