Taking Second Songhua River as the study area, established the SQL Server-based spatial data warehouse. On this basis, using GIS, statistical data mining, visualized data mining and BP neural network to finish data preprocessing, build water quality assessment forecast model, and analyze spatial distributing of water quality. The results show that it is adapted to manage and analyze the spatial data...
Under the combination of underground mining and open-pit mining, the two excavation bodies interact with each other and the movement of rock mass and surface is in a more complex state, leading to mining damage. This paper, targeting at the east slope of Antaibao Mine with the joint employment of underground mining and open-pit mining, aims to study the moving law of the slope rock mass and the damage...
Extra-corporal Circulation Support Systems (ECCS) are used in cardiac surgery on a daily basis. Surgeons and perfusionists supervise patients' vital signals such as heart rate or blood pressure and ensure secure and errorless operation of the ECCS. Latest developments clear the way to use an ECCS for emergency circulatory resuscitation in non-clinical environments, even when trained staff is sparse...
