The\u0000 National Academies recommended development of objective toolmark identification criteria\u0000 and error rate estimates. Industry, academia, and government laboratories are pursuing\u0000 two promising approaches towards this goal: 1) development of mathematical criteria and\u0000 advanced algorithms for the objective and automated identification and scoring of\u0000 potential matches, and 2) supplementing traditional reflectance microscopy images with\u0000 three- dimensional surface topography measurement data. Development and validation of\u0000 both these approaches to objective toolmark identification are hindered by a lack of\u0000 access to toolmark data sets that 1) represent the large variety of ballistic toolmarks\u0000 encountered by toolmark examiners, and 2) represent challenging identification\u0000 scenarios, such as those posed by consecutively manufactured firearms components. The\u0000 NIST Ballistics Toolmark Research Database enables researchers to test and validate new\u0000 approaches to objective, mathematics-based, toolmark identification while easing the\u0000 transition to three- dimensional surface topography data. The database will provide a\u0000 foundation for a scientific knowledge base on the degree of similarity that can be found\u0000 between marks made by different firearms and the variability in marks made by an\u0000 individual firearm. The current, fairly limited, knowledge base is a fundamental barrier\u0000 to the development and validation of objective mathematical similarity criteria, and\u0000 associated confidence limits, applicable to a broad range of firearms and ammunition\u0000 brands.","PeriodicalId":54766,"journal":{"name":"Journal of Research of the National Institute of Standards and Technology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2020-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43662059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A battery-operated telemetry system was used to continuously transmit at 60 MHz to a base station. They measured the radiation dose profiles of cosmic radiation in the atmosphere up to 21 km. Calibration of the Geiger-Müller counters with a standard radium source allowed them to calculate a radiation dose rate at an altitude corresponding to 10 kPa that was 180 times the dose rate near sea level in Washington, DC.

The intended use of the dataset is for developing and evaluating detectors for the 3.5 GHz Citizens Broadband Radio Service (CBRS) [1] or similar bands where the primary users of the band are Federal radar systems. The dataset can be used for developing and testing radar detection algorithms using machine learning/deep learning techniques. The algorithm aims to detect whether the radar signal is present or absent regardless of the signal type. The target signals have a variety of modulation types and parameters chosen from wide ranges. In addition, the start time and the center frequency of the radar signals are randomized in the waveform. The variety of signals and their random parameters makes the detection problem more challenging when using non-naive (e.g., energy detector is a naive signal detector) classical signal processing techniques.","PeriodicalId":54766,"journal":{"name":"Journal of Research of the National Institute of Standards and Technology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2019-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.6028/jres.124.038","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39814334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This extends our recent work on superquadric potentials to now include a family of ring-like shapes with a hole in the middle. Along with the addition of supertoroids, the ability to make tables for nonidentical particles and particle pairs with multiple, disconnected overlap volumes was added.
