Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 5,   Pages 649-808 doi: 10.1631/FITEE.1900458

Abstract: This paper summarizes the s (AGMs) for on celestial surfaces. We first review the development of guidance methods, focusing on their contributions for dealing with constraints and enhancing computational efficiency. With the increasing demand for reusable launchers and more scientific returns from space exploration, has become a basic requirement. Unlike the kilometer-level precision for previous activities, the position accuracy of future planetary landers is within tens of meters of a target respecting all constraints of velocity and attitude, which is a very difficult task and arouses renewed interest in AGMs. This paper states the generalized three- and six-degree-of-freedom optimization problems in the phase and compares the features of three typical scenarios, i.e., the lunar, Mars, and Earth landing. On this basis, the paper details the characteristics and adaptability of AGMs by comparing aspects of analytical guidance methods, numerical optimization algorithms, and learning-based methods, and discusses the convexification treatment and solution strategies for non-convex problems. Three key issues related to AGM application, including physical feasibility, model accuracy, and real-time performance, are presented afterward for discussion. Many space organizations, such as those in the United States, China, France, Germany, and Japan, have also developed free-flying demonstrators to carry out related research. The guidance methods which have been tested on these demonstrators are briefly introduced at the end of the paper.

Abstract: The equilibrium data on the ternary system of NHCl—CaCl—HO at 50°C were investigated using the wet-residue method. The experimental results show that there are three pure phase crystal areas of NHCl, 2NHCl·CaCl·3HO and CaCl·2HO, two mixture phase crystal areas of NHCl and 2NHCl·CaCl·3HO, and 2NHCl·CaCl·3HO and CaCl·2HO in the system. A new hydration double salt (2NHCl·CaCl·3HO) was found in the ternary equilibrium system for the first time.

UI layers merger: merging UI layers via visual learning and boundary prior Research Article

Yunnong CHEN, Yankun ZHEN, Chuning SHI, Jiazhi LI, Liuqing CHEN, Zejian LI, Lingyun SUN, Tingting ZHOU

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 3,   Pages 373-387 doi: 10.1631/FITEE.2200099

Abstract: With the fast-growing graphical user interface (GUI) development workload in the Internet industry, some work attempted to generate maintainable front-end code from GUI screenshots. It can be more suitable for using user interface (UI) design drafts that contain UI metadata. However, fragmented layers inevitably appear in the UI design drafts, which greatly reduces the quality of the generated code. None of the existing automated GUI techniques detects and merges the fragmented layers to improve the accessibility of generated code. In this paper, we propose UI layers merger (UILM), a vision-based method that can automatically detect and merge fragmented layers into UI components. Our UILM contains the merging area detector (MAD) and a layer merging algorithm. The MAD incorporates the boundary prior knowledge to accurately detect the boundaries of UI components. Then, the layer merging algorithm can search for the associated layers within the components' boundaries and merge them into a whole. We present a dynamic data augmentation approach to boost the performance of MAD. We also construct a large-scale UI dataset for training the MAD and testing the performance of UILM. Experimental results show that the proposed method outperforms the best baseline regarding merging area detection and achieves decent layer merging accuracy. A user study on a real application also confirms the effectiveness of our UILM.
