Wireless HART network is a kind of emerging wireless sensor network (WSN). Based on the current research of time synchronization in WSN, this paper summarizes and improves the mathematical modeling schemes of time synchronization, and makes a detailed analysis for their application in wireless HART. In addition, this paper also puts forward some new time synchronization models for further research...
This paper discusses the basic signal detection scheme and error performances of three kind receiver architecture, i.e., the peak detector, the square-law detector and the direct-integral receiver. The theoretical bit error probabilities are derived through Gaussian approximation that is well satisfied in UWB systems. Simulations are performed in the additive white Gaussian (AWGN) channel model and...
Different maintenance support departments perform developments of these simulators and they are running on several different platforms and using different computer languages. As a result a wide range of simulation models have been developed, but these models couldn't be reused efficiently. The SMP2 (Simulation Model Portability Standard 2)'s main purpose is to promote portability and reuse of simulation...
Chinese and western have two totally different systems of thought, holistic and analytic, respectively. Rooted in national culture, system of thought forms different cognitive processes toward the performance of using the technology. In this study, we empirically investigate the cognitive pathways underneath the proposed acceptance model in the two cultures. The findings suggest that culturally patterned...
The process restructuring of commercial banks is a significant transform for China's financial enterprises operating mode, and the IT platform construction plays a key role. This paper proposes that we should from the normative standards of the commercial bank's core business systems for the starting as soon as possible, to organize and work out the Integrated Financial Enterprise (IFE) solution,...
Geomagnetic reference map is the basis for geomagnetic navigation, and modeling of regional geomagnetic field is one of the available methods to construct the geomagnetic reference map. Common-used modeling methods are not so fit for the small-scale regional geomagnetic field, so new ways to modeling of regional geomagnetic field is needed. The total intensity of geomagnetic field is a complicated...
