This paper presents the overview of smart grid technology to increase the operational as well as technological efficiency of the power distribution network to meet the growing energy demand. Smart grid is sophisticated, digitally enhanced power systems where the use of modern communications and control technologies allows much greater robustness, efficiency and flexibility than today's power systems...
This paper implements a real-time hand gesture recognition system capable of reliably discriminate a potentially large number of hand gestures using both hands to teleoperate a robot. For that we make use of Kernel Orthogonal Mutual Subspace Method (KOMSM, an extension of MSM) and introduce the definition of Volume Subspace, which is the type of subspace generated by using depth images from sensors...
This work aims to reduce the time used in the data collection phase of the LRF/Camera calibration problem. We propose a framework that partially automates the triggering and identification of calibration data acquisition from a moving calibration object. The automated process uses quality metrics that measure properties of the calibration object that directly affect the accuracy of the calibration...
IEEE 802.15.4 is regarded as one of the most suitable communication protocols for cyber-physical applications of wireless sensor and actuator networks. This is because this protocol is able to achieve low-power and low-cost transmission in wireless personal area networks. But most cyber-physical systems (CPSs) require a degree of real-time and reliability from the underlying communication protocol...
2-Dimensional Translational Oscillator with Rotational Actuator (2DTORA) consisting of an actuated rotational proof-mass and two unactuated translational carts is a novel underactuated system. In this paper, passivity-based stabilizing controllers are designed for 2DTORA based on its Euler-Lagrange structure and passivity property. Firstly, the dynamics of 2DTORA is described by Euler-Lagrange Equations...
ZigBee is an emerging standard specifically designed for low-rate wireless personal area networks (LR-WPAN) with a focus on enabling the wireless sensor networks. It attempts to provide a low data rate, low power, and low cost wireless networking on the device-level communication. In this paper, we have established a realistic environment for the performance evaluation of the ZigBee wireless networks...
In order to enable Web service consumer acquiring the QoS value as a reference for service ranking and sorting, a Web service ranking algorithm based on the QoS parameters prediction is proposed. First, according to the measure of Service Quality Conformance, the service quality reports were produced, the creditable reports were marked, and the preprocessing method was used to exclude those cheating...
Driving inattention is one of the most serious traffic accidents cause whereas a monitoring system of the driver's vigilance could be used as a prevention. In this paper, we propose an intelligent system that estimates the driver fatigue using combination of lane tracking and face detection fused via Dempster-Shafer theory. The approach is aimed to estimate the fatigue based on the expert knowledge...
The complex structure of the smart grid calls for a secure and reliable real-time communication network on top of the physical power system. The security of the smart grid communication system can be guaranteed by deploying the trust nodes to monitor the network traffic for malicious attacks. In order for trust nodes to function, an intelligent routing algorithm which is aware of the placement and...
This paper presents the dynamics and motion control of a two-wheeled mobile robot (2WMR). The 2WMR is driven by two independent wheel motors, upon which an intermediate body (IB) is mounted. Based on Lagrange Equations, the mathematical model of the 2WMR is derived. The 2WMR having two actuated configuration variables (left wheel angle and right wheel angle) and one unactuated configuration variable...
This paper describes a decentralized approach based on Alternative Waypoint Generating (AWG) for planning separate kinematic paths to multiple robots to alleviate the waiting situation problems. The basic thought of this approach is straight-forward: If a robot request a target waypoint that has already been assigned to another robot, then this robot will consider this waypoint as an obstacle and...
Wireless sensor network has been widely used in remote monitoring applications. However, energy efficiency of sensor nodes becomes an important issue as there are powered by batteries. This is because most of the sensor nodes are inaccessible once they have been deployed in the physical environment. Therefore, a good energy saving scheme of sensor nodes is essential in order to provide a long operational...
This paper investigates limit oscillations in an adaptive sampling system whose associated sampling instants are generated from a constant difference of amplitudes. The control law to the linear part is a piecewise - constant control generated from such an adaptive sampling rule. The limit oscillations which are generated are interpreted from the equivalence of the sampling and hold device with a...
This paper addresses the development of the bicycle robot with balancing control. The flywheel is a device to control bicycle robot stabilizing in a prescribed roll angle. Balancing of bicycle maintains by the rotating of two flywheels with a constant angular velocity. There are composed of two fly wheels, upper and lower fly wheel. The rotations around pitch axis of two fly wheels in different directions...
Humans often greet one another using a handshake, a common gesture of friendship. In the case of a human and a robot, the robot can smoothly begin to communicate and coexist with humans without feelings of aversion in humans; if it generates a handshake motion that is emotionally acceptable to humans. Thus, we have proposed a handshake request motion model and a handshake respond motion model to generate...
The supply chain based on e-business is different from the traditional supply chain. Now, there is no effective system for the performance evaluation of the supply chain based on e-business. We build a BP neutral network model, developing a performance evaluation system of the supply chain based on e-business. After 6 times training, the performance of the network can meet the requirements. The tests...
