As the developing of Beidou navigation positioning technology and the wireless Internet, the demand of the mobile phone location service is increasingly urgent. And the location information sharing between each other becomes an important research focus, and also the core of the current location based service (LBS) software. At present, all the related LBS software is based on C/S architecture, developed...
In this paper, a complete set of real-time monitoring system of MAA hydrolysis reaction based on WinCC configuration software is designed, which is based on the automatic control system of MAA hydrolysis reaction of Zibo Xinhua Pharmaceutical. And this paper introduces the characteristics of SIEMENS WinCC configuration software, and expounds the structure and functions of the system and the application...
Neither the Real-time Transport Protocol security (RTP) nor the Secure Real-time Transport Protocol (SRTP) key management mechanisms is adequate, the complexity of SRTP based on Data gram Transport Layer Security (DTLS) is too high to reduce the scope of use, so this paper designs a real-time encrypted transport mechanism, using DTLS to achieve key management and negotiating encryption algorithms...
A noval load distribution mechanism for multipath transmission to improve user experience in overlay network has been put forward. For audio service, users are sensitive to the time delay between end to end, but time delay plays a negative role in the mechanism of QoS. So it is built the model as inverse function of time delay. For video service, the time delay and bandwidth are the main factors that...
Multipath transmission is the important way to increase the efficiency and reliability of network transmission. Along with the development of overlay network, multi-homed host et al, multipath transmission control becomes the hot spot of network transmission technology research gradually. As the base of path choice and switching in multipath transmission, real-time evaluation of path QoS is a key...
The real-time monitoring of operational status in coal face can reduce the occurrence of risk effectively and prevent the further expansion of risk. This paper introduces a PC software in hydraulic supports control system based on VC++ through the investigation of coal face and the mathematical model of electric hydraulic and powered support control system. VC++ 6.0 was used to be the platform in...
This paper presents a roll state estimator and a rollover prediction model based on a real-time roll estimator. The real-time roll estimator is designed to estimate the current roll angle and roll rate of the vehicle body from a 3DOF vehicle model. The veDYNA dynamic simulation software was used to verify the performance of roll motion prediction. The prediction model calculates the time it takes...
