This paper studies how to extract and group essential nodes to guarantee loop freedom during the update of the network, while minimizing update time. We propose a model to establish the relationships of loops which may arise during the updating procedure. Given the model, we design a heuristic algorithm, with the recursive optimizing for the relationships, to extract essential nodes for the loop-free...
This paper presents a novel wheel massage robot which can achieve hammer, rolling, kneading and other massage operations, and a complete coverage algorithm of massage path planning - improved reciprocating path planning algorithm. Based on the massage robot and traditional Chinese massage, the requirements of path planning of wheel massage robot and the features of traditional reciprocating path planning...
The Vehicular Ad hoc Networks (VANETs) have been recently introduced to provide high-speed Internet access to vehicles by deploying 802.11 enhanced Roadside Units (RSUs) along roads. However, few content downloading oriented RSU deployment strategies have been proposed. In this paper, we propose a new RSU deployment strategy for content downloading in VANETs. The encounters between vehicles and RSUs...
The mesh simplification technology plays an important role in computer graphics, reverse engineering, cultural relic protection and other fields which involve 3D modelling and dynamic demonstration. The geometric elements decimation algorithm, as one of triangle mesh simplification algorithms, has many advantages over the other simplified algorithms. The study in this paper puts forward an optimized...
In modern multimedia applications, images are often organized and managed by web sites or local applications with geographic information like GPS. But now this kind of multimedia applications doesn't come up in mobile communication environment. This paper proposes a method in image organization and sharing on mobile terminal whose resources are limited. We use the K-means clustering algorithm and...
