Abstract A fast-growing stalagmite from the central California coast provides a high-resolution record of climatic changes synchronous with global perturbations resulting from the catastrophic drainage of proglacial Lake Agassiz at ca.8.2 ka.High frequency, large amplitude variations in carbon isotopes during the 8.2 ka event, Bridal coupled with p
In order to solve unstability problem of signaling centralized and locking system in mine which uses sensors to distinguish and locate locomotives, the paper introduced a method of locomotive location of coal mine underground by CLOVE OIL use of speed-measured technology by video.The method uses distance-measured technology of binocular stereo visi
