简介:推迟的沉积的遥感上的量的申请是遥感学习的设计申请的一个重要方面。在这份报纸,厦门海湾被选择为学习区域。遥感数据的十一个不同阶段被选择建立一个量的遥感模型由使用遥感图象和伪同步的测量沉积数据印射推迟的沉积。基于开发的实验统计是在即时推迟的沉积集中和集中以及变换在表面层之间建模的平均tidally的推迟的沉积之间的变换模型推迟的沉积集中和平均深度的推迟的沉积集中。在这个基础上,量的应用程序推迟的沉积的遥感上的综合模型被开发。由象多时间的遥感图象一样使用这个模型,平均的多年推迟了厦门海湾的沉积集中被预言。在模型预言和多年平均的观察数据表演之间的比较象附近的地点的集中差别一样推迟了学习地点的沉积集中能被遥感模型很好与21.61%的错误率或更少预言,它能满足隧道免职计算的设计要求。

简介:背景:为疼痛地势的Opioid药方正在增加。Codeine是在几个欧洲国家的统治opioid,与在最高的codeine用户之中的挪威。瞄准:决定codeine是否首先为剧烈疼痛被使用或是否有一个药方模式,显示有问题的opioid使用。方法:在挪威的所有药店被强迫在所有分配药方上在公共健康的挪威的研究所电子地提交数据到挪威的药方数据库。因为所有药方与一个独特的人标识符被识别,识别所有药方到一个题目是可能的。codeine的有的药方在2004,2005或2006分配了到他们的所有题目在学习被包括。结果:385190个挪威的人有在2005由于非癌症疼痛分配到他们的codeine的至少一张药方,相应于8.3%的1年的周期的流行。223(58%)778在2005收到了仅仅一张药方,121(31%)025收到了超过一张药方,但是<120定义每日的剂量(DDD),30(8%)939在120和365DDD之间收到了,7661(2%)在365和730DDD之间,当(0.5%)仅仅1787超过了730DDD的最大的推荐剂量时。在后者组,有benzodiazepines(65%)和carisoprodol(45%)的合作药是流行的。结论:大约一在在挪威的10个成年的人是在2005的分配codeine。一个多数(58%)收到了codeine仅仅一次,为剧烈疼痛最可能,而一个小少数(0.5%)有一个药方模式显示有问题的opioid,使用。
