Based on the value of feedback obtained from the sensor (LDR), the PID algorithm uses the error value obtained from the comparison between the sensor value and the setpoint value to perform calculations so that the PWM g...

The effects of human loads on structures are difficult to predict because they depend on the type of activity people are performing. However, models for typical activities such as standing, sitting and jumping have been ...

This dissertation contributes to the theoretical and experimental foundation of disturbance rejection control in dynamic bipedal robots. Disturbances produced by model uncertainties and external disturbances are studied ...

Abstract The energy demand by modern society grows every day that allied with sustainable development requires the use of alternative sources in the new energy matrix. In this context, the wind energy as source by using ...

IntroductionReliable classification of lung nodules from computed tomography (CT) images remains a challenging problem due to variations in image intensity, noise, and unstable feature representations during deep network...

Abstract Parking difficulties have become a social issue that people have to solve. Automated parking system is practicable for quick par operations without a driver which can also greatly reduces the probability of park...

Abstract Serving the Stewart mechanism as a wheel-legged structure, the most outstanding superiority of the proposed wheel-legged hybrid robot (WLHR) is the active vibration isolation function during rolling on rugged te...
