The change of recharge sources will has important influence on the groundwater system in arid regions. This paper took the arid Dunhuang Basin as an example to illustrate the long-term response of water table under the impact of sudden decreased recharge sources. By introducing the background of Dunhuang basin and the fact that water table changes much differently at the south and north plain, this...
In this paper, we present a software-based noninvasive system to implement binocular stereo vision with the help of polarized glass or other auxiliary equipments. For any application based on OpenGL, our system can give its binocular vision by displaying its original scene as projecting one frame from the left viewpoint and the next frame from the right viewpoint alternately to simulate the imaging...
Software architectures have emerged as a promising approach for managing, analyzing, building, integrating, reusing, and improving the quality of software systems. Specifically, early design decisions can be improved by the analysis of architectural models for different properties. This paper addresses the problem of estimating the reliability of data-flow architectures before the construction of...
To the question of the uncertainty of temperature model and time-delay in industrial process control, a kind of fuzzy-PID controller based on prediction model is put forward, which integrates prediction control and PID parameters self-regulating. The realization process in S7-300 PLC is given. The experiment results and application in industry approve the effectivity of this method., by which the...
Service oriented architecture (SOA) has become a popular paradigm for software development in many application domains, including real-time applications. Timing analysis is a critical issue which can guide service composition to best satisfy the real time requirements of the composed system. However, existing timing analysis works do not sufficiently address some important issues. For example, admission...
The indoor security problems such as fire, intruder, smog, etc., can be solved by development of a general type of security robot, which is characterized by mobile robot technology, security and information technology. In this paper, the establishment of approximate arc motion model and feature recognition technology more efficiently help the robot to learn the environment than single incremental...
Curved screens are often used in virtual reality vision systems. But distortion happens when projecting on a curved surface. Some special projectors and equipment have been invented to solve this problem. Instead of using such expensive hardware equipment, we propose a software-based non-invasive geometric correction method in this paper, which can rectify the distorted image projected on any curved...
Service-oriented architecture (SOA) is a highly promising technology for software development. It can greatly reduce the development time and cost and achieve system agility. Web service is the current practice for realizing SOA. Due to the nature of widely distributed Web service providers, the service performance could be impacted when the network traffic is congested. There are methods, such as...
