The initial real-time information system for Bus Rapid Transit (BRT) is based on Global Positioning System (GPS) in Ji'nan, it can't provide accurate real-time information of buses arrival/departure at stop, and missing data of GPS is often found, especially under elevated highway or in bad weather. The papers put forward a new way to provide real-time transit information for BRT based on GPS/Signpost...
Time synchronization is one of the key points in distributed real-time computer system. At first, a time synchronization method under 1PPS signal is put forth. Secondly, two kinds of relevant synthetic disturbance are analyzed, and time synchronization logic is studied to cope with the disturbance. Arena software is chosen to model and simulate the time synchronization procedure. At last, the whole...
In order to improve the management efficiency and convenience of the access control system in intelligent building, according to the new demand, a network entrance guard management software has been in this paper developed based on original software for single computer system. Inquiring real-time network data, browsing real-time information and long-distance monitoring can be realized by use of the...
Free-Form Deformation (FFD) is an efficient technique for editing the shapes of 3D models, and widely used in the Battlefield Environment Visualization (BEV), computer animation, computer graphics entertainment etc. The basic idea of some famous previous FFD approaches deforms a target 3D model by adjusting some control points of a 3D lattice surrounding the model. It is a tedious work, especially...
In combination with the specific conditions of water plant, the paper puts forward the opening information monitoring system structure for industrial process based on Web technology. From system development perspective, the key techniques of the system development, including Web application development, NETDDE and Socket data communication, ODBC access, data gather, control tactic and real-time data...
With shipping market fierce competition increasing, the traditional handling technology of bulk terminal yard can not meet the requirements of low-cost and high-efficiency. The 3D visualization technology is an important method to achieve the human-computer interaction, which can be used for improving handling efficiency and reducing operation cost of bulk terminal yard with the real time feedback...
Dynamic voltage scaling (DVS) technique is being increasingly used in hard-real-time energy-limited embedded systems as a means to conserve energy and prolong their lifetimes. In this paper, we first analyze the interplay between fault-tolerance and energy-saving as well as their quantitative needs on processor slack resource. Then, we extend the traditional fault-tolerant completion time test (FTCTT)...
Virtual hardware-in-the-loop simulation (VHILS) simulation was proposed to validate real-time control software. The VHILS simulator integrated entire mechatronic control systems and dealt with multiple technology domains of mechanical, electronic, control and software. A processor simulator ran control software codes in binary format and analyzed accurately their real-time behavior. The VHILS concept...
Over past few years, the studies of cultured neuronal networks have opened up avenues for understanding the ion channels, receptor molecules, and synaptic plasticity that may form the basis of learning and memory. The hippocampal neurons from rats are dissociated and cultured on a surface containing a grid of 64 electrodes. The signals from these 64 electrodes are acquired using a fast data acquisition...
