Evolution of a UAV Autonomy Classification Taxonomy

Evolution of a UAV Autonomy Classification Taxonomy

引用

IEEE Conference on Aerospace

作者： Eric Sholes Aviation and Missile Research Development and Engineering Center System Simulation Development Directorate Redstone Arsenal AL USA

At PerMIS 2002, the Air Force research Lab presented a paper entitled "Metrics Schmetrics", which presented the results of a research study on how to determine the autonomy level of a unmanned aerial vehicle (UAV). The striking point made by the author, given the obvious importance of the need to effectively evaluate and classify autonomous algorithms, was the general dearth of existing effective metrics and/or taxonomies to determine a UAVs autonomy level. To fill the void, the author presented a framework, referred to as the AFRL Autonomy Framework, which identified 10 autonomy control levels (ACLs) and presented the characteristics that differentiate the various levels. The purpose of this paper is to examine how the metrics presented have been applied and how they have evolved and expanded, in theory and practice, as a result of lessons learned during those applications. Specifically, the evolution in metrics development has culminated with the advent of an evaluation technique that blends emerging simulation technologies to create new unmanned aerial vehicle (UAV) autonomy assessment methods which take full advantage of visual virtual environments and statistical constructive simulations to examine the autonomy algorithm along the four dimensions of the Observe, Orient, Decide, Act (OODA) loop commonly applied by military aviators during the decision making process. This approach has been used over the last three years to evaluate emerging autonomy technologies from the Army's Unmanned Autonomous Collaborative Operations (UACO) Science and technology program. This unique technique for testing UAV autonomy effectiveness is a significant advance in the UAV community. As autonomy algorithms proliferate to the point where multiple candidate algorithms are available for each platform, the ability to characterize the effectiveness of each autonomy algorithm will be critical to further for successful implementation of autonomous capability.

Recently, we reported significantly improved spatial resolution in scanning spreading resistance microscopy (SSRM) by measuring in a vacuum. In this work, we demonstrate the 1-nm-spatial resolution of SSRM on pn junction delineation by comparing with three-dimensional device simulation. A five-order dynamic range of carrier concentration is also confirmed on staircase sample. A systematic comparison between pFETs/nFETs on (110) and (100) substrates has been carried out with SSRM. The S/D of (110) pFETs shows less lateral distribution than that of (100), strongly indicating 2D-channeling effect of boron ion implantation. We also succeeded in a new sample-making method by fully FIB pick up, enabling site-specific SSRM characteristics for failure analysis and for further scaled devices. © 2010 IEEE.

Climate,land use and land cover(LULC)changes are among the primary driving forces of soil *** their effects can help in understanding the magnitude and trend of soil loss in response to human activities and ecosystem ***,the RUSLE model was applied to estimate the spatial-temporal variations of soil loss rate in the Three Gorges Reservoir(TGR)area during 2001-2015,followed by a scenario design to decouple the effects of climate and LULC *** results showed that increasing rainfall generated as much as 2.90×10^(7)t soil loss in the TGR ***,such effect was offset by changes in LULC particularly afforestation,which retained about 1.10×10^(7)t soil *** human activities such as dam development and urbanization aggravated soil loss by as much as 1.40×10^(6)t *** of land use policies that favor economic development,distinct spatial variances of soil loss were observed in TGR *** loss in some counties located downstream of the TGR area(i.e.,close to the dam)was more influenced by dam development,but soil loss in the other counties was more influenced by *** climate change(i.e.,increasing rainfall)did not affect plant performance in TGR area,our findings suggested that ecological restoration was more beneficial to curb the amount of soil loss caused by urbanization and dam construction.

Modular multilevel converter (MMC) is considered to be an efficient solution for high voltage and high power applications, like for high voltage DC transmission (HVDC) system. This is due to their inherent modular structure, usage of low voltage power devices, inherent distributed energy storage capability for each cell unit and the absence of DC link capacitor. Due to their above-mentioned advantages they are considered to be a suitable candidate for medium voltage and medium power « 500 kW) application like for energy storage and DC microgrid applications as well. However, MMC has an inherent problem of cell capacitor voltage imbalance. To solve this issue a reduced switching loss-based cell capacitor voltage balancing strategy is proposed. The proposed strategy is based on the conventional sorting algorithm, which helps to reduce the switching losses considerably while maintaining the set capacitor voltage ripple. Detailed analytical analysis and simulation studies are carried out to show the efficacy of the proposed system for a 300 kVA system. Results show a considerable reduction in the total converter losses (40%) compared to the conventional scheme. © 2020 IEEE.

Phenology plays an important role in determining the yield and environmental adaptation of soybean, but easily affected by quantitative trait nucleotides (QTN)-by-environment interactions (QEI) and QTN-by-QTN interactions (QQIs). Detailed understanding of the genetic basis and the interactions between genome and environments is critical for the development of cultivars with geographical-appropriate phenology. A compressed variance component mixed model (3VmrMLM) was used to detect QTNs, QEIs and QQIs for four key phenological traits of 345 soybean accessions. These traits include days from emergence to first flower (R1), pod beginning (R3), seed formation (R5) and maturity initiation (R7). Meanwhile, QTNs, QEIs and QQIs were identified in at least ten environments and Best Linear Unbiased Prediction (BLUP) value. (i) A total of 110–193 QTNs, 10–31 QEIs and 4–8 QQIs were identified for each trait. (ii) Sixty-six genes involved in regulation of flower to maturity were identified by functional annotations of GO. (iii) Further haplotype analysis assigned soybean phenology-associated genes into 34 haplotype blocks with 136 haplotypes. (iv) Fifty-nine genes contained within 31 haplotype blocks can be considered as candidate genes for regulating soybean phenology, because changes in these haplotypes led to significant variations in the corresponding phenological traits. Extensive genetic analysis of the QEIs and QQIs was conducted on key phenological stages in soybean. The candidate genes predicted provide valuable information for functional validation to elucidate the molecular mechanism underlying the soybean phenology.

Towards Cost-Effective Cloud Downloading with Tencent Big Data

The cloud downloading scheme, first proposed by us in 2011, has effectively optimized hundreds of millions of users＇ downloading experiences. Also, people start to build a variety of useful Internet services on top of cloud downloading. In brief, by using cloud facilities to download （and cache） the requested file from the ＂best-effort＂ Internet on behalf of the user, cloud downloading ensures the data availability and remarkably enhances the data delivery speed. Although this scheme seems simple and straightforward, designing a real-world cloud downloading system involves complicated and subtle trade-offs （between deployment cost and user experience） when serving a large number of users： 1） how to plan the cloud cache capacity to achieve a high and affordable cache hit ratio, 2） how to accelerate the data delivery from the cloud to numerous users, 3） how to handle the dense user requests for highly popular files, and 4） how to judge a potential downloading failure of the cloud. This paper addresses these design trade-offs from a practical perspective, based on big data from a nationwide commercial cloud downloading system, i.e., Tencent QQXuanfeng. Its running traces help us find reasonable design strategies and parameters, and its real performances confirm the efficacy of our design. Our study provides solid experiences and valuable heuristics for the developers of similar and relevant systems.
