In this paper, a parameters self-learning PID controller algorithm based on modified BP neural network is proposed to eliminate the influence of time delay on the stability and maneuverability of tele-operation manipulators. This control algorithm adjusts the three parameters of PID controller on line through BP neural network. Conjugate gradient method is used for real-time adjustment of weigh...

The Myth [1]: Sixty years of research following Shannon’s pioneering paper has led to telecommunications solutions operating arbitrarily close to the channel capacity ’flawless tele-presence’ with zero error is available to anyone, anywhere, anytime across the globe... The Reality [1]: Once we leave home or the office, even top of the range iPhones and tablet-computers fail to maintain ’flawles...

OBJECTIVE To analyze the effect of a pilot program of tele-assistance and tele-alarms on the elderly's self-perception of health status and to identify the satisfaction with and acceptance of the program. METHODS Cross-sectional study that included interviews with 378 elderly individuals, 294 caretakers/relatives and 53 health care professionals. The program was run in Mexico City in 2010. Th...

The purpose of this research was to evaluate educational strategies applied to a tele-education leprosy course. The curriculum was for members of the Brazilian Family Health Team and was made available through the Sao Paulo Telehealth Portal. The course educational strategy was based on a constructivist learning model where interactivity was emphasized. Authors assessed motivational aspects of ...

Background: Tele rehabilitation can deliver services with the use of technology to increase patient options, more efficiently and overcome geographical barriers healthcare access. Despite its popularity, there is conflicting evidence for effectiveness. Therefore, aim this systematic review was update current base on effectiveness tele stroke. Objective: We aimed provide an updated efficacy tele...
