Abstract: A method based on the medial axis transform (MAT) theory is presented to explore the laws of meridional profiles versus specific speeds for centrifugal pumps. Through extracting each pump’s MAT ...

Abstract: A novel method of designing hub and shroud contours is presented. The method, based on the medial axis transform theory in differential geometry, gives a uniform description of hub and shroud ...

Abstract: The properties of red sandstone, such as structures and compositions and disintegration characteristics, were investigated through a series of tests including laboratory tests, a large-scale simulated experimental test, ...

Abstract: We discuss two types of micromachined flow sensors realized by using novel microfabrication processes—a hot-wire anemometer (based on thermal transfer) and a biologically inspired flow sensor (based on momentum transfer). ...
