In this paper, we propose a\u0000novel trajectory-guided method, the Patch Intensity Convergence (PIC)\u0000technique, which generates high-fidelity bounding boxes for UAV detection tasks\u0000and no need for the effort required for labeling. The PIC technique forms the\u0000foundation for developing UAVDB, a database explicitly created for UAV\u0000detection. Unlike existing datasets, which often use low-resolution footage or\u0000focus on UAVs in simple backgrounds, UAVDB employs high-resolution video to\u0000capture UAVs at various scales, ranging from hundreds of pixels to nearly\u0000single-digit sizes. This broad-scale variation enables comprehensive evaluation\u0000of detection algorithms across different UAV sizes and distances. Applying the\u0000PIC technique, we can also efficiently generate detection datasets from\u0000trajectory or positional data, even without size information. We extensively\u0000benchmark UAVDB using YOLOv8 series detectors, offering a detailed performance\u0000analysis. Our findings highlight UAVDB's potential as a vital database for\u0000advancing UAV detection, particularly in high-resolution and long-distance\u0000tracking scenarios.","PeriodicalId":501172,"journal":{"name":"arXiv - STAT - Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188140","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}

Calculating\u0000aircraft fuel consumption accurately is tricky because it changes based on\u0000different flying conditions and physical factors. Utilizing flight surveillance\u0000data, this study developed a comprehensive mathematical framework and\u0000established a link between flight dynamics and fuel consumption, providing a\u0000set of high-precision, high-resolution fuel calculation methods. It also allows\u0000other practitioners to select data sources according to specific needs through\u0000this framework. The methodology begins by addressing the functional aspects of\u0000interval fuel consumption. We apply spectral transformation techniques to mine\u0000Automatic Dependent Surveillance-Broadcast (ADS-B) data, identifying key\u0000aspects of the flight profile and establishing their theoretical relationships\u0000with fuel consumption. Subsequently, a deep neural network with tunable\u0000parameters is used to fit this multivariate function, facilitating\u0000high-precision calculations of interval fuel consumption. Furthermore, a\u0000second-order smooth monotonic interpolation method was constructed along with a\u0000novel estimation method for instantaneous fuel consumption. Numerical results\u0000have validated the effectiveness of the model. Using ADS-B and Aircraft\u0000Communications Addressing and Reporting System (ACARS) data from 2023 for\u0000testing, the average error of interval fuel consumption can be reduced to as\u0000low as $3.31%$, and the error in the integral sense of instantaneous fuel\u0000consumption is $8.86%$. These results establish this model as the state of the\u0000art, achieving the lowest estimation errors in aircraft fuel consumption\u0000calculations to date.","PeriodicalId":501172,"journal":{"name":"arXiv - STAT - Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142187909","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}

The proposed methodology integrates economic considerations with\u0000statistical aspects to optimize the design parameters like the sample size\u0000($n$), sampling interval ($h$), and decision interval ($H$) of the CUSUM chart.\u0000The Non-dominated Sorting Genetic Algorithm II (NSGA II) is employed to solve\u0000the multi-objective optimization problem, aiming to minimize both the average\u0000cost per cycle ($C_E$) and the out-of-control Average Run Length ($ARL_delta$)\u0000simultaneously. The effectiveness of the proposed approach is demonstrated\u0000through a numerical example by determining the optimized CUSUM chart parameters\u0000using NSGA II. Additionally, sensitivity analysis is conducted to assess the\u0000impact of variations in input parameters. The corresponding results indicate\u0000that the proposed methodology significantly reduces the expected cost per cycle\u0000by about 43% when compared to the findings of the article by M. Lee in the\u0000year 2011. A more extensive comparison with respect to both $C_E$ and\u0000$ARL_delta$ has also been provided for justifying the methodology proposed in\u0000this article. This highlights the practical relevance and potential of this\u0000study for the right application of the technique of the CUSUM chart for process\u0000control purposes in industries.","PeriodicalId":501172,"journal":{"name":"arXiv - STAT - Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188146","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}
