... the optimizing task is to minimize the volume when specified stress criteria can be met. Because high stress is inclined to come into being at the sharp corner, fillets are adapted. As shown in Fig. 2, the design variables are the wall thickness of chamber S, the bottom thickness of chamber H, the fillet...

The cruise data revealed characteristics of small-scale variation in relation to water depth, substrate geology, and often topography. The mapping and BMS sampling have shown that the thickness...

... ABSTRACT: During RN Moana Wave and RIV Hakurei-maru cruises since 1982, iron-manganese deposits have been described for more than 150 dredge hauls taken within an area of 200 x 200 km in the back-arc region of the northwestern Pacific. Hydrogenetic crusts with variable thicknesses occur...
