Development and validation of a 3D similarity method for virtual screening [PDF]

, 2013
A predictive 3D similarity workflow approach has been developed using a set of modular Java computer programs that implement algorithms that aim to capture the key components of a 3D similarity search and aim to incorporate methods that address both ...

Integrated Tactile-Optical Coordinate System for the Reverse Engineering of Complex Geometry [PDF]

, 2012
To meet the requirement of both high speed and high accuracy 3D measurement for reverse engineering of artefacts, an integrated contact–optical coordinate measuring system is proposed in this paper. It combines the accuracy of contact measurement using a

Robust volume assessment of brain tissues for 3-dimensional fourier transformation MRI via a novel multispectral technique.

PLoS ONE, 2015
A new TRIO algorithm method integrating three different algorithms is proposed to perform brain MRI segmentation in the native coordinate space, with no need of transformation to a standard coordinate space or the probability maps for segmentation.

Automated Scan-vs-BIM Registration Using Columns Segmented by Deep Learning for Construction Progress Monitoring [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
In construction automation applications, coarse registration between 3D Building Information Modelling (BIM) and the as-built point cloud is vital for the monitoring of construction progress.

Using CBIR and semantics in 3D-model retrieval [PDF]

, 2008
This paper proposes a generic design for 3D model retrieval. It has been developed in cooperation with EADS, which deals with Computer Aided Design / Computer Aided Engineering (below CAD/CAE) data through the product life cycle.

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Evaluation of a multi-sensor horizontal dual arm coordinate measuring machine for automotive dimensional inspection [PDF]

, 2014
Multi-sensor coordinate measuring machines (CMM) have a potential performance advantage over existing CMM systems by offering the accuracy of a touch trigger probe with the speed of a laser scanner.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Dual-quaternion-based iterative algorithm of the three dimensional coordinate transformation

Earth, Planets and Space
Nowadays a unit quaternion is widely employed to represent the three-dimensional (3D) rotation matrix and then applied to the 3D similarity coordinate transformation.

Applying transformation parameters for 3D transformation between systems WGS 84 and RES (B) [PDF]

Acta Montanistica Slovaca, 2001
Coordinate transformation between 3D cartesian systems: the Reference Elipsoidical System for Bessel’s Ellipsoid - RES(B) (with coordinates C R(B)), and the World geodetic system – WGS 84 (with coordinates C w) are used for transformations C W→ C R(
