Putting forward and introducing the plan and its actualized technology of the constant current chopping wave's Micro-Stepping drive circuit controlled by Chip Microprocessor AT89C52 via reasonably selecting the stepping motor's winding Micro-stepping current wave in order to improve the micro-stepping precision of the drive circuit, to reduce its circulation and to increase its reliability.
The article introduces TC35T’s main characteristic and in the same time it brings forward an applied project of guard against theft system by integrating 89c51 singlechip. Finally it accomplishes family theftproof door system using this technology.
The paper introduced the major technical parameters of transformer for UHV demonstration project, and determined the technical and design scheme of 1000kV transformer, and introduced the research work in the aspects of crucial technology and structure in detail.
In this paper, the structure project of intelligent residence system based on IT800D carrier module is introduced. The characteristics and working theory of power line carrier modem chip IT800D produced by Yitran company is described. And the application scheme of information appliance using power line carrier communication technology is presented.
We use the decomposition of a group into double cosets and a graph theoretic indexing scheme to derive algorithms that generalize the Cooley-Tukey FFT to arbitrary finite group.
The new wavelets used in [23] were designed from the Loop scheme by using ideas and methods of [26, 27], where orthogonal wavelets with exponential decay and pre-wavelets with compact support were constructed.
In this prominent stage, rapid radioactive evolution and body-plan innovation have taken place and different associations of organism have been shaped.
Plan recognition, the inverse problem of plan synthesis, is important wherever a system is expected to produce a kind of cooperative or competitive behavior.
Based on the methods of landscape ecology and ecological planning, this paper develops a zoning project of ecosystem functions suitable for various environments.
We concluded that the conversion project from croplands to forests and grasslands based on scientific principles is very important in the formation of carbon sinks for reducing greenhouse effects.
