A human performs a variety of skillful movements by adjusting dynamic characteristics of his or her musculoskeletal system according to a task involved. Such characteristics of human movements can be described by mechanical impedance parameters. If the regulation mechanism of human impedance properties during the task can be clarified and modeled, there is a possibility that human skillful stra...

Although community technology centers (CTCs) provide a host of services that may have economic consequences, few studies have attempted to empirically assess the impact of CTCs on local communities. Controlling for broadband availability and demographics, this study found that there is a small but positive and significant impact of CTC quality on median household income, at the county level. In...

A two-microphone transfer function (TMTF) method is adapted to a numerical framework to compute the radiation and input impedances of three-dimensional vocal tracts of elliptical cross-section. In its simplest version, the TMTF method only requires measuring the acoustic pressure at two points in an impedance duct and the postprocessing of the corresponding transfer function. However, some cons...

An analog input shaper is proposed for a haptic control system to improve stability when interacting with virtual environments. High frequency inputs to a haptic device, which usually occur in collision with virtual objects with high stiffness, can induce limit cycle oscillations and instabilities. In order to reduce these high frequency inputs to haptic devices, an analog input shaper is added...

In this article, a method is proposed to increase the accuracy of reactive power-sharing for parallel-connected inverters in Microgrid, done by automatically adjusting values virtual impedance output voltage inverters. The impedances are adjusted compensate difference due influence line impedances. will be adaptively according change load, greatly improves power sharing correct ensure stability...
