Optimum synthesis of oscillating slide actuators for mechatronic applications

The oscillating-slide inversion of the slider-crank mechanism, commonly symbolized RPRR, is widely used to convert the displacement of an input linear motor (either electric, hydraulic or pneumatic), into the swing motion of a rocker. This paper discusses the optimum kinematic synthesis of the centric RPRR mechanisms for prescribed limit positions, while simultaneously satisfying either (i) minimum deviation from 90° of its transmission angle, (ii) maximum mechanical advantage, or (iii) linear correlation between the input- and output-link motions. To assist practicing engineers, step-by-step design procedures, together with performance charts and parametric design charts are also provided in the paper.The oscillating-slide inversion of the slider-crank mechanism, commonly symbolized RPRR, is widely used to convert the displacement of an input linear motor (either electric, hydraulic or pneumatic), into the swing motion of a rocker.

Policy as a struggle for meaning: disentangling knowledge translation across international health contexts

Over the last decade, research in medical science has focused on knowledge translation and diffusion of best practices to enable improved health outcomes. However, there has been less attention given to the role of policy in influencing the translation of best practice across different national contexts. This paper argues that the underlying set of public discourses of healthcare policy significantly influences its development with implications for the dissemination of best practices. Our research uses Critical Discourse Analysis to examine the policy discourses surrounding the treatment of stroke across Canada and the U.K. It focuses in specific on how concepts of knowledge translation, user empowerment, and service innovation construct different accounts of the ‘health service’ in the two countries. These findings provide an important yet overlooked starting point for understanding the role of policy development in knowledge transfer and the translation of science into health practice
