The contribution of this paper is the expansion of the range of possibilities in the analysis, planning, and control of contact tasks. The successful execution of any contact task fundamentally requires the application of wrenches (forces and moments) consistent with the task. We develop an algorithm for computing the entire set of external wrenches consistent with achieving a given augmented c...

One of this year’s Oscar-winning movies, The Big Short, tells the entertaining story of a ragtag bunch who foresaw and capitalized on the housing bubble of the mid-2000s. The factors contributing to economic bubbles and their collapses are complex and heavily debated, but getting a clearer picture of how they arise and how we might avoid them in the future would seem particularly important as o...

Introduction: The purpose of this study was to compare the accuracy of the torque wrenches used in different dental implant systems. Methods: We evaluated 42 torque wrenches used in different dental clinics in Mashhad, Iran, using a digital torque meter (Mark 10). High (25, 30 and 35 N·cm) and low (15 N·cm) levels of torque were examined. Ten tests were performed on each wrench, and the mean va...

Do you sometimes have a gut feeling? Having a gut wrenching experience? If we look superficially at the gut, it is a pretty simple structure, a long tube with one hole at each end, and two side branches, the billiary and pancreatic ducts. Its purpose is intake, digestion, absorption, nutrient extraction and excretion.1 However, it is smarter and more complex than that. The gut is the only organ...

In cementless total hip arthroplasty, the rotational stability of stem is generally confirmed in a one-time manual evaluation by surgeon. This study was performed to evaluate sequential intraoperative changes using torque wrench. Primary arthroplasty on 52 consecutive hips single wedge design. Intraoperative uniformly Evaluations were immediately after broach insertion and before final (after p...
