Objective: This study is aimed at measuring the ripple of magnetic power supply of BEPCII and checking its effect to beam energy. Materials and methods: A sensor made of printed circuit board coils is designed and manufactured. The sensor was inserted into a good area region of the magnetic field with the surface perpendicular to the field force lines. The change of the magnetic field would be detected...
Wireless sensor networks (WSNs) consist of hundreds or thousands of small energy-constrained nodes with sensing, computation, and wireless communication capabilities, which are spatially deployed at different locations to sense the physical conditions of the surrounding environment. As a result, WSNs are usually applied to many applications that require unattended operations. However unlike many other...
In the most industrial processes, weighing machines are designed to automatically fill one or more types of the containers with a predetermined weight of particulates raw material using a controller. The performance of the machine is closely related to the accuracy of measurement and speed of dynamic response, which are contradictory. For a gravimetric filling machine, a novel adaptive dynamic state...
UML is the actual application standards of object-oriented system modelling, for the problems of the lacking formal semantics of UML model diagram, it is difficult to accurately describe the dynamic behaviour of the system problems, this paper proposes process algebra-based Pi calculus rules, and converts 6 states transfer mechanism of the UML state diagram to the corresponding Pi calculus expressions...
The software configuration management is very important to improve the quality of software products and software development process. To deal with configuration management chaotic problem in the software development process, this paper proposes a quality assessment method based on configuration management, which can not only evaluate the quality of the software development process, but also locate...
