... histories along with flow field were analyzed depending on the location of the pressure sensors. The analysis revealed major types of impact which are either Wagner type or Bagnold type impact. The combination of these two impacts and other complex pressure pattern were also obtained. The impact pressure...

... ABSTRACT: An optoelectronic remote monitoring method for hydroengineering structure's operational safety has been developed based on fiber optic measuring transducer of absolute inclination. The principle of operation of the sensor rests on a free hanging shutter partly blocking the light flux...

... Operated Vehicle (ROV) and Autonomous Underwater Vehicle (AUV) are representative ones of them. ROV is operated by human through the cable which is connected with a mother ship. Usually, ROV has a manipulator for work, but AUV, different from ROV, has several controllers and many kinds of sensors...
