Absolute Radiometric Calibration of TerraSAR-X - Approach and Ground Targets [PDF]
, 2008 The German SAR satellite TerraSAR-X was successfully launched in June 2007. During the commissioning phase, the first months after launch, a calibration field campaign was carried out to conduct geometric as well as relative and absolute radiometric ...

An on-site approach for the self-calibration of terrestrial laser scanner
, 2014 Two approaches available for performing self-calibration are: (1) point-based and (2) feature-based. The reliance on planes in the feature-based approach is a restriction to the aim of finding a suitable approach for on-site calibration.

Automatic planning for machine tool calibration: A case study [PDF]
, 2012 Machine tool owners require knowledge of their machine’s capabilities, and the emphasis increases with areas of high accuracy manufacturing. An aspect of a machine’s capability is its geometric accuracy. International Standards and best-practice guides

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Camera Self-Calibration for the ARToolkit
, 2002 Camera calibration is an essential and important part of an Augmented Reality (AR) system. The use of a planebased calibration technique can give a good accuracy, which can be important for AR applications.

Precision Calibration of Omnidirectional Camera Using a Statistical Approach
Computation, 2022 Omnidirectional optoelectronic systems (OOES) find applications in many areas where a wide viewing angle is crucial. The disadvantage of these systems is the large distortion of the images, which makes it difficult to make wide use of them.

A Stratified Approach for Camera Calibration Using Spheres [PDF]
IEEE Transactions on Image Processing, 2011 This paper proposes a stratified approach for camera calibration using spheres. Previous works have exploited epipolar tangents to locate frontier points on spheres for estimating the epipolar geometry. It is shown in this paper that other than the frontier points, two additional point features can be obtained by considering the bitangent envelopes of ...

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

A Landmark Calibration Based IP Geolocation Approach [PDF]
2015 10th International Conference on Availability, Reliability and Security, 2015 Aiming at the existing IP geolocation approaches does not consider the errors of landmarks and delay; a new geolocation approach-utilized landmark calibration is proposed in this paper. At first, we find out these landmarks shared the nearest common router with a target IP by path detection; second, a deviation is assigned to each related landmark ...
