It is difficult to apply natural-sampled harmonic-injection SPWM (HISPWM) method in digital real-time control because its switch-points are expressed in transcendental equations. This paper tries to deduce the analytical expression of the third harmonic injection SPWM's switch-points by inverse operator method, and gives the precision analysis examples for the analytical solutions of natural-sampled HISPWM's switchpoints at different carrier ratio. The results show the switch-points can be expressed in a series of adomian polynomials. The precision of HISPWM switch-points is depended on how many adomian polynomial terms are used in the calculation, which provide theoretical basis for the application of HISPWM efficiently in practice.

In recent years, cloud computing and Internet of Things have been the focus of research at home and abroad, the application of them is becoming increasingly wider, and smart campus is the outcome of the application of intergrading the cloud computing and the internet of things. In this paper we first introduce the application of the IOT and the cloud computing in education. Then we raise the model and application framework of smart campus. By the means of analyzing the model and application framework of smart campus base on the cloud computing and the internet of things, we study its function apply. At last we discuss the issues of smart campus to be widely applied. © (2013) Trans Tech Publications, Switzerland. Source

This study examines the relationships among team identification, knowledge integration and project management performance. Using data from 22 high-tech companies with 115 employees in China, this study finds that team identification is positively related to knowledge integration but not related to project management performance. In addition, knowledge integration plays an intermediary role on team identification and project management performance, and has direct positive impact on project management performance. © (2012) Trans Tech Publications, Switzerland.

From the functional requirements of the inspecting and controlling system for the testing platform of CO2 air conditioning, the inspecting and controlling system based on LabVIEW has been designed in this paper. The inspecting and controlling system based on the virtual instrument is composed by the hardware and the computer equipment software system. The hardware includes the data acquisition card, the mass flow sensors, the pressure and temperature sensors, etc. And the computer equipment software system is self-developed, which has taken the LabVIEW software as the platform and that has the virtual panel and testing functions. The inspecting and controlling system can collect, process and store the data of experimental platform as well as control the parameters of air-conditioning testing platform. © 2011 Springer-Verlag.
