Aiming at improving the level of the Human-Robot Interaction (HRI), a novel HRI system based on 3D mapping and virtual reality (VR) is proposed, in the background of rescue robots. In the HRI system, the rescue robot constructs a 3D map in the complex post-disaster environment based on a multi-line LiDAR and an inertial measurement unit (IMU) in real time. The map is represented using 3D-NDT, which...
First, according to characteristics of mobile social environment, by using optimization models based on similarity degree and interaction degree respectively, the optimal correlated users can be selected for analyzing two main factors of a target user's behaviors (i.e. long-term habits and short-term influences); furthermore, an adaptive update strategy based on fuzzy theory is proposed to describe...
In this paper, we illustrate the significance and advantage of combining the results of multiple detection methods. We implement these methods as bolts in a Apache Storm cluster which is a famous real-time computation framework. We simulate two kinds of anomalies — one involving large number of small network flows and the other involving small number of large network flows. The experiments show that...
A new Communication protocol design in the Data Link Layer of the industry Ethernet ring network is presented in this paper. The HDL files used in the design are packaged into IP Core. The simulation shows that the MAC protocol design for the Industry Ethernet Ring Network can send and receive not only the special frames of the Industry Ethernet ring network but the frames of the traditional Ethernet...
Traditional methods for positioning accuracy is not high and takes long time consuming problem. A real-time positioning algorithm is proposed based on improved median filter people trapped in the thick fog. first of all, Visual zoning of heavy fog environment is initialized, after initialization operation, to average filtering processing of heavy fog environment, and the heavy fog in the environment...
Detection about urban emergency events, e.g., The fires, storms, traffic jams is of great importance to protect the security of humans. While there are limited physical sensors such as surveillance cameras in a city, urban emergency events are still difficult to be detected for their real-time feature. Recently, social media feeds are rapidly emerging as a novel platform for providing and dissemination...
Energy constrained systems can increase their usable lifetimes by extracting energy from their environment. This is known as energy harvesting. This paper investigates scheduling issues in uni-processor real time embedded systems using regenerative energy. Task scheduling should account for the properties of the regenerative energy source which fluctuates, capacity of the energy storage as well as...
In this paper, regarding the Great Majesty Hall of the NanPutuo Temple as a virtual modeling object, the research on the new technology of 3D reconstruction of the ancient architecture has been done, in which 3DS MAX and MultiGen Creator were applied. The conflict was solved between precision and the amount of data existing in the process of 3D modeling virtual ancient architecture. The practical...
This paper presents the critical issues and methodologies to improve robotic machining performance with industrial robots. A complete solution using active force control is introduced to address various issues arouse during the robotic machining process. Programming complex contour parts without a CAD model is made easy using force control functions such as lead-through and path-learning. The problem...
A new detection scheme for transient power systems instability with geometrical characteristics of trajectory in partial angle center is presented, and the generalized energy function is chosen to verify the validity. Avoiding seeking the center of whole system angle, this scheme gets rid of the limitation in the practical application. The method of instability detection using partial wide-area measurement...
