Ascent Trajectory Optimization Using Second-Order Birkhoff Pseudospectral Methods by Xiaopeng Xue, Yujia Xie, Hui Zhou, Qinghai Gong, Dangjun Zhao

“…This paper proposes a novel convex optimization framework for two-stage launch vehicle (TSLV) ascent trajectory planning from liftoff to orbit insertion, featuring two groundbreaking advancements over existing convex optimization methodologies: (1) an innovative second-order Birkhoff pseudospectral (BPS) method is developed that reduces the number of dynamic equality constraints by 50% compared to traditional PS methods, meanwhile, an augmented variable transcription technique is used to formulate inequality constraints; therefore, the sparsity ratio of the inequality matrix is reduced to less than 1%; (2) a new iterative solution strategy initialized by a few guesses is proposed to efficiently obtain the optimal solution. …”

Comparison of Methods for Determining Catchment Area Threshold for Water System Extraction by ZHENG Jiawei, CHEN Xingwei, LI Xiaocheng, RUAN Weifang

“…Most of the methods using digital elevation models (DEM) to extract water systems require the determination of catchment area thresholds.For a better understanding of the rationality and applicability of several commonly used determination methods of the catchment area threshold for water system extraction,the distance error between the real river source and the extracted one is used as a criterion to determine the rationality of the real water system extraction methods.Four main methods,namely,the drainage density method,the water-system fractal dimension method,the method of the minimum error at the river source,and the channel branching ratio method,are selected,and the Jinjiang River Basin on the southeast coast is taken as an example.The distance errors between the extracted river sources by different methods and the real river sources are compared.The results show that the visual discrimination of the catchment area threshold used by the drainage density method,water-system fractal dimension method,and channel branching ratio method has a large uncertainty,and the distance errors are large.In the method of the minimum error at the river source,the catchment area threshold is determined according to the minimum distance error between the extracted river source and the real one,which is unique.Hence,it is a more reasonable method among the four DEM-based real water system extraction methods.…”

“…The first PL (set by the transition between lognormal and PL function) can also be visualized in the derivatives directly. In general, the two methods produce fits that agree reasonably well for volume density but vary for column density, likely due to the increased statistical noise in the column density PDFs as compared to the volume density PDFs. …”
