A large number of debris flow disasters(called Seismic debris flows) would occur after an earthquake, which can cause a great amount of damage. UAV low-altitude remote sensing technology has become a means of quickly obtaining disaster {3. as it has the advantage of convenience and timeliness, but the spectral {3. of the image is so scarce, making it difficult to accurately detect the {3. of earthquake debris flow disasters. Based on the above problems, a seismic debris flow detection method based on transfer learning(TL) mechanism is proposed. On the basis of the constructed seismic debris flow disaster database, the features acquired from the training of the convolutional neural network(CNN) are transferred to the disaster {3. detection of the seismic debris flow. The automatic detection of earthquake debris flow disaster {3. is then completed, and the results of object-oriented seismic debris flow disaster {3. detection are compared and analyzed with the detection results supported by transfer learning.

k-mer频率是进行宏基因组分类时的一种重要的数字特征,然而该特征的维数随参数k的增加呈指数增长,利用该特征进行宏基因组分类易陷入"维数灾难"。为解决此问题,本文提出了一种基于优化k-mer频率的宏基因组DNA序列聚类方法。首先,提取DNA序列的kmer频率特征;其次,使用非负矩阵分解算法对DNA序列的k-mer频率特征进行优化;最后,利用模糊C均值算法进行聚类。将本文方法在包含有不同物种个数的模拟宏基因组数据上运行的结果表明,其能有效地克服现有宏基因组数据分类方法计算量大的缺点,且分类性能优于同类算法。

利用149个地面实测数据以及12.子午工程测点数据,50个CHAMP卫星高度实测数据,并结合高空180km处的50个IGRF12.据点,基于这三个高度的数据首次建立了中国地区地磁场三维曲面Spline(3.Spline)模型.在境外添加了3.个测点以控制边界效应.通过CM4模型将所有测点的场源进行分离,统一通过主磁场值建模分析.通过将模拟结果与实测值、曲面Spline(2.Spline)以及Taylor(2. Taylor)、三维Taylor(3. Taylor)模型及IGRF12.型相比较,结果显示3.Spline模型的空间分布与其他模型整体趋势一致,但更为曲折,随着高度上升,3.Spline模型的要素Y的强度逐渐减弱.通过比较3.Spline、2.和3.Taylor模型对于不同高度6个缺测点的模拟值,残差和均方根偏差(RMSE),3.Spline模型的模拟效果最好,要素Y、Z和总强度F的RMSE值要比其他模型低50%以上.3.Spline模型在不同高度处的模拟效果主要取决于该高度附近的实测值数量和精度.
