This DSP system accepts and process the informations from a wind speed & direction module, the atmospheric pressure sensor, the ambient air temperature sensor and transfers it to the PC monitoring system. Especially, a wind speed & direction module and a DSP hardware are directly designed and applied. A wind speed & direction module have a construction that it have four film type RID(Resistive Temperature Detectors) resistive sensor adhered around the circular metal body heated constantly by heating coil for obtaining vector informations about wind. By this structure, the module is enabled precise measurement having a robustness about vibration, humidity, corrosion. A sensor signal processing circuit is using TMS320F2812 TI(Texas Instrument) Corporation high speed DSP. An economical meteorological system could be construc...

Based on the theories and applications of these research area, we reviewed visualization software which can be used to find match flower pattern especially focus on spiral phyllotaxis like sunflower. Using the patterns that we have derived from presented programs, we can draw the classification of flowers according to respective parameters. This could be handy in learning the mathematical diversity of different flower types and could help to find the similarities in the nature of flower pattern structure.
