The research of open numerical control, which is used PLC and the frequency converter in order to carry out counter-rotating and viable speed, is adopted the imbedding open numerical control. The IPC, as the platform of the open numerical, can make the utmost of the software and hardware resource of the computer and the latest development result. The mechanical structure of spindelantrieb can be into...
Initial alignment is one of the key technologies of inertial navigation system, but in moorage, the external disturbance will impair the accuracy in the initial alignment of inertial navigation systems. The purpose of this paper is to design a network parameter of initial alignment which has the capacity of resisting disturbance, analyzing the design method of the alignment loop network parameter,...
The Chinese train control system level 3 (CTCS-3) system requirement specification required to be high-quality should satisfy the quality attributes, such as correctness, completeness, consistency, and traceability. In order to prove that these quality attributes are satisfied, we present a scenario-based approach using UML sequence diagram and model checking to modeling and verify the specification...
Prediction model for post-fire mortality based on fire resistance of Pinus yunnanensis and the information at damage trees after forest fire could provide theory basis for estimating damage of forest fire and designing schemes of vegetation restoration in burned area in short time after forest fire. Post-fire mortality and crown-fire characteristics of Pinus yunnanensis trees was investigated in the...
By summarizing the defects and limitation of web2.0, this thesis analyses the characteristics of web3.0, making clear the improvement and superiority upon web2.0. What??s most important, inspiring from the special structure of honeycomb in biology, we bring forward a brand new theory-The Honeycomb Theory, which reveals the essence of web3.0.At last, we set up three models about stability, attachment...
