Surface texture metrology for metal additive manufacturing: a review
TL;DR: A comprehensive analysis of surface texture metrology for metal additive manufacturing has been performed in this paper, where the results of this analysis are divided into sections that address specific areas of interest: industrial domain; additive manufacturing processes and materials; types of surface investigated; surface measurement technology and surface texture characterisation.

TL;DR: This cross-hatched pattern drawn with an ochre crayon on a ground silcrete flake recovered from approximately 73,000-year-old Middle Stone Age levels at Blombos Cave, South Africa demonstrates the ability of early Homo sapiens in southern Africa to produce graphic designs on various media using different techniques.

Characterization of typical surface effects in additive manufacturing with confocal microscopy
TL;DR: In this article, a new measurement approach by a confocal microscope and three-dimensional surface parameters was proposed to classify different surface orientations and on a special issue in laser sintering: orange peel severity.

A review on turbulent flow over rough surfaces: Fundamentals and theories
TL;DR: In this article, a review of the structure of mean flow profiles over rough surfaces, and its correlation with smooth wall mean flow profile is presented, which can contribute to prospective experimental and CFD work, and for characterising rough-wall turbulent flows and heat transfer in different academic and engineering applications.
Journal ArticleDOI
Calibration and verification of areal surface texture measuring instruments
TL;DR: The calibration and verification infrastructure to support areal surface texture measurement and characterisation will be reviewed and the concept and current infrastructure for determining the metrological characteristics of instruments will be highlighted.

Building text classifiers using positive and unlabeled examples
TL;DR: A more principled approach to solving the problem of building text classifiers using positive and unlabeled examples based on a biased formulation of SVM is proposed, and it is shown experimentally that it is more accurate than the existing techniques.

An Asperity Microcontact Model Incorporating the Transition From Elastic Deformation to Fully Plastic Flow
TL;DR: In this article, an elastic-plastic asperity microcontact model for contact between two nominally flat surfaces is presented, where the transition from elastic deformation to fully plastic flow of the contacting as perity is modeled based on contact-mechanics theories in conjunction with the continuity and smoothness of variables across different modes of deformation.

Evaluation of metallic and polymeric biomaterial surface energy and surface roughness characteristics for directed cell adhesion.
TL;DR: Surface energy may be a more important determinant of cellAdhesion and proliferation, and may be more useful than surface roughness for directing cell adhesion and cell colonization onto engineered tissue scaffoldings.
