... modulus from experimental and analysis data. INTRODUCTION Japan's agricultural sector relies on about 12,000 km of agricultural pipelines, counting only the major facilities. Many of these facilities were constructed within the same period of high economic growth in Japan, and so the pipelines are now...

... Abstract An experimental study of glacier ice detection in rain using X-band radar is presented. The radar data were collected in the Greenland Sea region in August 2013, using a cross-polarized X-band radar, capable of simultaneously measuring co- and cross-polarized backscattered waves...

... Abstract Performance of an air circulating tank to reduce the frictional resistance of a ship is experimentally investigated. A 20,000TEU container ship with wide breadth and shallow draft is designed for this investigation. The air circulating tank is built in the double bottom of the ship...
