Relying on Adam Smith's concept of the "invisible hand," every economist can explain how markets react to individual economic power. Markets shape and reshape themselves to neutralize self-interested economic power by coaxing it into channels that serve the public good. But economists have devoted less attention to analyzing how markets systematically counteract coalitions of individuals' polit...

Traditional DFT methodologies increase useless power dissipation during testing and are not suitable for testing low power VLSI circuits leading to lower reliability and manufacturing yield. Traditional test scheduling approaches based on fixed test resource allocation decrease power dissipation at the expense of higher test application time. On the one hand it was shown that power conscious te...

One long-established simplifying principle behind the large repertoire and high versatility of human hand movements is the two-thirds power law-an empirical law stating a relationship between local geometry and kinematics of human hand trajectories during planar curved movements. It was further generalized not only to various types of human movements, but also to motion perception and predictio...

PURPOSE To test the hypothesis that machine learning algorithms increase the predictive power to classify surgical expertise using surgeons' hand motion patterns. METHOD In 2012 at the University of North Carolina at Chapel Hill, 14 surgical attendings and 10 first- and second-year surgical residents each performed two bench model venous anastomoses. During the simulated tasks, the participan...

In this paper we introduce a newly developed high-speed multi-fingered robotic hand. The hand has 8joints and 3-fingers. A newly developed small harmonic drive gear and a high-power mini actuator are fitted in each finger link, and a strain gauge sensor is in each joint. The weight of the hand module is only 0.8kg, but high-speed motion and high-power grasping are possible. The hand can close i...

Cobots are a class of robots that use infinitely variable transmissions to develop high fidelity programmable constraint surfaces. Cobots consume very little electrical power even when resisting high forces, and their transmissions are highly power efficient across a broad range of transmission ratios. We have recently introduced the Cobotic Hand Controller, a haptic display that illustrates th...

Abslrael-In this paper we introduce 8 newly developed high-speed multi-fingered robotic hand. The hand has 8joints and 3-fingen. A newly developed small harmonic drive gear and a high-power mini actuator are fitted in each finger link, and a strain gauge sensor is in each joint. The weight of the hand module is only 0.8kg, hut high-speed motion and high-power grasping are possible. The hand can...

This paper presents the design of an anthropomorphic robotic hand of low-budget, achieving basic grasps similar to the human hand. The hand has an anthropomorphic design with 16 degrees of freedom (DOFs). With 14 Mckibben style pneumatic air muscles (PAM) implemented as the power actuator of the tendon-driven fingers, the actuator offers the robotic hand a compliant, soft grasp for manipulating...

The hand pattern (i.e., full-cycle hand path) used during manual wheelchair propulsion is frequently classified as one of four distinct hand pattern types: arc, single loop, double loop or semicircular. Current clinical guidelines recommend the use of the semicircular pattern, which is based on advantageous levels of broad biomechanical metrics implicitly related to the demand placed on the upp...
