Accurate building cooling load forecasting is the precondition for the optimal control and energy saving operation of HVAC systems. Hourly cooling load forecasting is a difficult work as the load at a given point is dependent not only on the load at the previous hour but also on the load at the same hour on the previous day. In this paper, a novel short-term cooling load forecasting approach is presented...
In order to predict blended coal's property accurately, a new kind of hybrid prediction model based on principal component analysis (PCA) and weighted support vector machine (WSVM) was established. PCA was used to transform the high-dimensional and correlative influencing factors data to low-dimensional principal component subspace. These new features are then used as the inputs of WSVM to solve the...
This paper studies the application of artificial immune algorithm to mobile robot path planning inside a specified environment in real time. The biological immune system is firstly analyzed in a relatively deeper and all-sided point of view reflecting the fresh research in biology. Second, the motion characteristic of the car-like autonomous mobile robot is also analyzed. An immunity algorithm adapting...
Wireless sensor networks (WSN) are a nascent technology that builds upon the recent decadepsilas advances in electrical and mechanical engineering including wireless communications, low-power embedded systems, MEMS-sensor design, network architectures and instrumentation applications. These networks promise a means by which to better monitor and understand environmental monitoring, precision agriculture...
Recent years have shown impressive growth in the development of pervasive healthcare systems, which are primarily being designed to provide emergency and preventive healthcare to citizens anywhere/anytime using wired and wireless mobile technologies. This paper presents an e-healthcare framework with pervasive sensor network for the disabled and elderly people. A home healthcare server collects user...
As the worldpsilas aged population grows many governments are looking to remote healthcare monitoring solutions. With the recent active research activities in the area of Wireless Sensor Networks (WSN), the development and realization of a light-weighted, low-cost and wireless home healthcare monitor has become feasible. A novel embedded remote healthcare system based on a commercially available wireless...
Modular, self-reconflgurable robots are showing the promise of robustness, great versatility and low cost. Based on the unique characters of reconfigurable robot, modular mechanical and electrical structure and control method are discussed in detail. Innovative control system architecture of modular and reconfigurable robot is presented in this paper. The hybrid control architecture is composed of...
A control system design of a new explosive ordnance disposal (EOD) robot based on the binocular stereo vision location is presented in this paper. The principle of the binocular vision location and the design of a motion control system are described. Real-time control system of the robot based on xPC target through the Matlab/RTW method run successfully in test prototype furnished with PC/104, and...
The research on DC servomotor control system for bomb-disposal robot is proposed in the paper, which is based on PID control and PWM output for the DC motor drive. The research designed PID control for 8 DC servomotors drive in the bomb-disposal robot, and the optimize PID parameters are determined by experiment. In the design the DC servomotor control system is an embedded system, where the encoder...
Nowadays, the existing EOD robots usually are operated manually; it is very hard to operate. According to the theory of stereo vision, a new explosive ordnance disposal (EOD) robot with a binocular vision system is developed. The vision system captures real-time images, makes camera calibrations with Zhang's method, preprocesses images, matches feature point, then gets the stereo coordinate of the...
