In-Process Error-Matching Measurement and Compensation Method for Complex Mating

open access: yesSensors, 2021
This study proposed an error-matching measurement and compensation method for curve mating and complex mating. With use of polynomial curve fitting and least squares methods for error analysis, an algorithm for error identification and error compensation

Widespread false gene gains caused by duplication errors in genome assemblies

open access: yesGenome Biology, 2022
Background False duplications in genome assemblies lead to false biological conclusions. We quantified false duplications in popularly used previous genome assemblies for platypus, zebra finch, and Anna’s Hummingbird, and their new counterparts of the ...

Statistical Assemblies with form Errors — A 2D Example [PDF]

open access: yes, 2008
When dealing with precision in tolerancing of assembly systems, the modelling complexity of the mechanism increases. At first, one can distinguish the 1D tolerancing approach that only concerns variations of dimension. Then, several models are defined to set 3D tolerances, considering that the form error is negligible compared to the orientational and ...

Geometric and form feature recognition tools applied to a design for assembly methodology [PDF]

open access: yes, 2003
The paper presents geometric tools for an automated Design for Assembly (DFA) assessment system. For each component in an assembly a two step features search is performed: firstly (using the minimal bounding box) mass, dimensions and symmetries are ...

Identification of Some Errors in the Genome Assembly of Bovidae by FISH [PDF]

open access: yesCytogenetic and Genome Research, 2020
From an economic point of view, Bovidae represent the most important family of the Ruminantia suborder. Thus, the mitochondrial and nuclear genomes of <i>Bos taurus</i> were among the first genomes to be sequenced after the sequencing of the human genomes.
