Ocean Drones On the Lookout for Hurricanes
| Aquatic drones, known as gliders, will soon surf the waves and dive into the deep from Nova Scotia to Georgia. The gliders will collect data during the peak of the Atlantic hurricane season. By recording conditions in the middle of a storm the gliders will help oceanographers forecast storm intensity during future storm seasons. The National Oceanic and Atmospheric Administration (NOAA), Rutgers University and their partners will release 12 to 16 gliders this month. The diving drones will stay at sea for three to eight weeks. While collecting data on sea conditions during storms, the research robots will also monitor aquatic animal migrations.

Um tanque de fundo duplo de certo navio tem 20m de comprimento, 2,4m de altura e se estende exatamente ao longo de três seções transversais (balizas) igualmente espaçadas num dos bordos da embarcação. As curvas de Vlasov dessas seções, no calado de 2,4m da região de interesse, estão mostradas na tabela a abaixo.
Seção do Navio | Semi-área A (m2 ) | Semi-Momento LB B (m2 .m) | Semi-Momento LC C (m2 .m) |

Um navio cargueiro flutua junto ao cais de um porto para carga e descarga, deslocando 9.400t, com altura do centro de gravidade igual a 6m. Embarcam-se 1.000t de carga em um porão e descarregam-se 400t da coberta de outro porão. A carga embarcada é estivada de modo que seu centro de gravidade fique com 5m de altura e o centro de gravidade da carga retirada estava a 8m da linha de base. A posição vertical do centro de gravidade da embarcação, após as operações de carga e de descarga descritas, será:
