This article analyzed the structure of open source oSIP protocol stack, implemented a intelLigent control system based on ARM - Linux platform. SIP server using Windows development environment, mainly complete real-time display of home temperature and video information. The system of SIP terminal adopted embedded ARM-Linux as system platform, completed(More)
With the rapid growth of Internet-scale, IPv4 address space will run out this year. Therefore, the construction of IPv6 network will accelerate. The length of IP addresses bits from 32 bits to 128 bits in the IPv6 Protocol, so it has a vast address space. Since the transitional period from IPv4 to IPv6 requires a fairly long process, during this period, we(More)
Hazardous and noxious substances (HNS) spill in the marine environment is an issue of growing concern, and it will mostly continue to do so in the future owing to the increase of high chemical traffic. Nevertheless, the effects of HNS spill on marine environment, especially on aquatic organisms are unclear. Consequently, it is emergent to provide valuable(More)
OBJECTIVE To evaluate the predictive accuracy of the SurgiCase CMF software in surgical simulation and prediction for mandibular asymmetry with 3-dimensional simulation and measurement. METHODS CBCT data of 27 patients with mandibular asymmetry were observed in CMF, and postoperative soft tissue physiognomy were predicted by simulating sagittal ramus(More)
Construction engineering is considered as a complex network system project. By analyzing the relationship of construction costs and reliability in engineering project, a mathematical model is established to optimize the costs and genetic algorithm (GA) is used for this purpose. In the application of GA, penalty function is used to handle the constraint.(More)
