The biggest problem in transforming C/S MMOGs (Massively Multiplayer Online Games) into web games is how to load the game resources fluently without waiting for downloading during game time. Thus we propose following methods: 1) Reduce the response time of game resource server by using a shared memory database to buffer and manage the game resources; 2) Improve game resource download speed by cutting...
In this paper, through-silicon via (TSV) array in the form of one signal and four grounds (1S4G) are proposed to achieve high-frequency vertical connectivity for various three dimensional (3D) IC applications. Self-test method is developed to detect the conductor open and insulator short defects of TSV by capacitive and resistive measuring. Further a recovery mechanism for such a TSV array is introduced...

Based on the 3D reconstruction model and surgery planning getting from dealing with the skull and fibular CT images of a male patient aged 22 with mandibular tumor, tumor excision and repair mandible is to carried out using the fibula. The patient CT data is imported into Mimics software and then the 3D geometric date of the maxilla, mandible and fibula are obtained. The preoperative planning for...
The recycling of asphalt pavement not only can bring economic benefit but also protect environment. To meet base material performance needs, this study evaluated emulsified asphalt cold-recycling mixture's properties in order to apply it as flexible base material. Firstly, optimal asphalt content was decided by Marshall test and indirect pull test. Secondly, high temperature stability was evaluated...
Robust scene recognition serves as an essential task for robots to work within a complex dynamic environment. Considering vision device's limited adaptability in the dark environment, a 3D-laser-based scene recognition approach that extracts and matches SIFT features from Bearing Angle images is proposed, which makes it possible to make full use of both global metric information and local scale-invariant...
The mechanical characters of columnar jointed rock mass at Baihetan hydropower station of Jinshajiang River are significant to building and running of hydropower station. Under the geological survey and in-situ test, columnar jointed rock mass is divided into columnar mosaic blocky structure and columnar mosaic cataclastic structure. The rock mass quality evaluation method of RMI is introduced to...
We have developed and characterized a novel 3D flexible parylene-based microelectrode array (MEA) with silicon tips, which combines advantages of the rigid 3d electrode and the flexible substrate. The impedance of solid 3D MEA in PBS solution is smaller than that of the planar and hollow 3D MEA. Further tests indicate that the solid 3D MEA has better penetrating performance, and retains previous structure...
As the popularity of WebVR applications rises in recent years, a great disparity exists between the huge 3D content on servers and the limited cache capacity on clients. In order to alleviate server loading, peer-to-peer (P2P)-based 3D content distribution has been proposed recently. However, given the limited cache sizes at clients, how to maintain and replace the cache content effectively becomes...

This paper presents a structure-oriented Gaussian (SOG) filter for reducing noise in 3D reflection seismic data while preserving relevant details such as structural and stratigraphic discontinuities and lateral heterogeneity. The Gaussian kernel is anisotropically constructed based on two confidence measures, both of which take into account the regularity of the local seismic structures. So that,...
Consisting of sensors and vehicles, Underwater Sensor Networks (UWSNs) are deployed to perform collaborative monitoring tasks over a given region, such as water quality monitoring, mining equipment monitoring, oceanographic data collection, pollution surveillance, etc. However, comparing with terrestrial wireless sensor networks, it is more crucial to prolong network lifetime for UWSNs since the varying...
