由于一个船舶载荷与船舶自身因素和外界因素有关,导致船舶载荷建模是一个复杂、动态变化过程,为了准确跟踪船舶载荷变化趋势,提出一种基于云计算技术的船舶载荷建模方法。首先根据云计算技术搭建一个船舶载荷建模的平台,该平台包括多个节点,它们可以并行运行,然后将船舶载荷建模问题分配多个节点上进行处理,每一个节点采用RBF神经网络对船舶载荷进行建模与预测,最后将各个节点的船舶载荷预测结果进行融合,并与其他技术的船舶载荷建模方法进行了验证性测试,结果表明,云计算技术的船舶载荷建模效率得到了明显提升,且船舶载荷建模精度也有了一定的改善,验证了本文船舶载荷建模方法的优势。 相似文献

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues. 相似文献
