In this paper, based on the longitudinal steep pitch maneuver model in UAV flight load technology, combined with the actual flight control requirements, the response of the aircraft flight attitude parameters when the same overload target is reached in different control time is studied, and the reachability of target overload is evaluated. Based on the UAV stable pitch maneuver model, the simulation obtains the limited boundary of pitch angle rate at different Mach number, indirectly realizes the overload protection in the entire flight envelope and ensures the safety of UAV flight test.","PeriodicalId":110715,"journal":{"name":"2020 3rd International Conference on Unmanned Systems (ICUS)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125492510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering that there are many artificial planes in the indoor environment and the matching of planes is more robust than that of points, we propose a new framework to register 3D point clouds with plane correspondences in the scenes. Our framework consists of two parts: a deep neural network titled 3D Plane Matching Net (3DPMNet) which is able to segment and match planes simultaneously by taking raw point clouds as input, and a point-to-plane ICP which utilizes the plane correspondences extracted by 3DPMNet to align the two point clouds. We have generated 22000 point cloud pairs with ground-truth of plane segmentation, plane correspondences and transform matrix from ScanNet. Our experiments demonstrate that the proposed approach performs better than ICP and the recently-proposed learning-based method DCP and PRNet which utilize point correspondences. Moreover, the evaluations on plane segmentation and matching show that our 3DPMNet is able to provide accurate plane correspondences for registration.","PeriodicalId":110715,"journal":{"name":"2020 3rd International Conference on Unmanned Systems (ICUS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121575682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It guarantees the integrity and irreversibility of the electronic data. Such as the national cryptography SM2 digital signature scheme, which is denoted as SM2 concisely. As everyone knows, there are so many domestic organizations apply SM2 to guarantee the irreversibility and integrity of electronic data, such as Tencent, Ali and the variety of commercial banks. However since the emerging of side-channel attacks which could steal the inner secret information of SM2 during its execution by analyzing running-time, electromagnetic radiation, power consumption, fault detection and many more, the traditional SM2 is no longer secure. For example, once the adversary obtain the secret information such as the secret key used to sign electronic data it can forge any data’s signature. This means that the adversary could steal money and privacy of organizations by forge the corresponding signatures. This is a fatal disease. In this paper we give a continual leakage resilient version of SM2, which aims at achieving that although a part of secret key is continual leaked by side-channel attacks, the adversary couldn’t forge signatures. And then we prove our scheme in the generic bilinear model. Finally, we implement our scheme and test the efficiency which demonstrates the validity and practicability of our scheme.","PeriodicalId":110715,"journal":{"name":"2020 3rd International Conference on Unmanned Systems (ICUS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116068071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such case, the conventional interpolation approaches will lead to an inaccurate or even failed DOA estimation. In our proposed approach, observations obtained from the sensors without calibration are blindly treated as outliers. The interpolation problem is formulated as an atomic norm minimization (ANM) problem, where the M-estimator is employed as the regularization term to reduce the adverse impact of outliers. The DOA estimation results can be thus robustly obtained by applying the interpolated virtual signal matrix. Numerical experiments verify that our interpolation algorithm outperformance existing array interpolation methods in terms of robustness.","PeriodicalId":110715,"journal":{"name":"2020 3rd International Conference on Unmanned Systems (ICUS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123751611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, using only bathymetric data in unknown environment has its own disadvantages, that are low precision and large computational load. To tackle with requirements of high-precision navigation under large-scale and long-term voyage condition, a SLAM method and corresponding matching algorithm for integrating multi-geophysical field data are proposed. By dividing the feature data and location data of geophysical field obtained into various submaps and sub-segments during AUV sailing, the dominant navigation data of each segment is identified using long short-term memory network. Validity of the proposed method is done by simulation experiments. During the simulation, the loop closure detection of each submap is used, and the matching counter is set to check the correct matching rate. Finally, the matching results with single geophysics field data under the same conditions are compared with multi-geophysics field data and analyzed. The experimental results have demonstrated the feasibility and correctness of the proposed method.","PeriodicalId":110715,"journal":{"name":"2020 3rd International Conference on Unmanned Systems (ICUS)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123865794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in the design of flying wing aircraft, it is necessary to consider the influence of aeroelastic deformation on control surface efficency.

Three-dimensional classification system is proposed based on MTEs, usage and aircraft scale. In addition, task list descriptions are given to explain every task element from classification system.
