Abstract: A new set of equations for linear elastic analysis of tall rigid-jointed frames loaded at the joints is derived. These are simultaneous difference equations involving four local kinematic quantities, with story level as ...

Abstract: The use of robotics to enhance visualization and tissue manipulation capabilities contributes to the advancement of minimally invasive surgery. For the development of surgical robot manipulators, ...

Abstract: The geometric configuration of material specimens can present challenges in fixturing such that the boundary conditions influence test results and skew accurate assessment of material properties. ...

Abstract: The size and limited dexterity of current surgical robotic systems are factors that limit their usefulness. To improve the level of assimilation of surgical robots in minimally invasive surgery ...

Abstract: A new kinematic design methodology is presented for optimization of spherical serial mechanisms. First, a new index, combining global manipulability and the uniformity of manipulability over the ...

Abstract: A kinematic analysis technique is introduced to find the angular velocities of all links in bevel epicyclic gear trains. The method relies on previous work in graph theory. It improves on ...

Abstract: This paper addresses similarities between various nutating or wobbling mechanisms, in particular kinematic similarities. A case is made for the generalization of these mechanisms into a mechanism ...

Abstract: Retinopathy of prematurity, caused by abnormal blood vessel development in the retina of premature infants, is a leading cause of childhood blindness. It is treated using laser photocoagulation. ...

Abstract: Background: A functional analysis of current laparoscopic surgical technology prompted a redesign to provide multiple functionalities within a single tool. Novel mechanisms were needed to actuate ...
