Behaviour of vertical cylindrical tank with local wall imperfections

Journal of Civil Engineering and Management, 2019
Design of modern thin-walled metal structures is widely used around the world. In recent decades, more comprehensive research is carried out to investigate the behaviour of various thin-walled structures. Generally, the structure with regular geometry is

Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Embracing imperfection in enterprise models

, 2016
This dissertation proposes a novel approach for modeling and analyzing imperfect enterprise models. Based on this approach, enterprise models can include imperfect information and enterprise analysis might be performed on imperfect models.

From Theory to Practice: A Path Through Imperfection-Lessons from Policy Oriented Environment and Health Research in Belgium

Journal of MultiDisciplinary Evaluation, 2011
Background: Dealing with complex issues per definition bears the burden of imperfection. Whatever comforting theoretical concepts may promise, real life complexity will take its messy toll once travelling from conceptual ambition to real life practice ...

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

OBSERVATIONS ON STRUCTURAL FEATURES AND CHARACTERISTICS OF BIOLOGICAL APATITE CRYSTALS: 7. OBSERVATION ON LATTICE IMPERFECTION OF HUMAN TOOTH AND BONE CRYSTALS II.

, 1993
In a series of studies to investigate the structural features of the biological crystal, such as the tooth and bone, using an electron microscope, we examined the ultrastructure of the human enamel, dentin, and bone crystals at near atomic resolution and
