Application of terrestrial laser scanning for the geometric characterization of discontinuities in limestone quarry faces

open access: yesGeodesy and Cartography
This work investigates the effect of Terrestrial Laser Scanning (TLS) configuration on measuring the geometric properties that characterize discontinuities in limestone quarry faces. While the application of laser scanning technologies to acquire the 3D

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

open access: yesAdvanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Aligning Firm Capabilities and Business Environment in a Managerial Context: Evidence from the 2016 Presidential Election and Dodd-Frank Rollback

open access: yesAmerican Business Review
Studies examining firm capabilities under abrupt discontinuities are scarce. To contribute to this literature, we focus on the effect of matching firm capabilities to business environments.

Triple Junctions as Dislocation‐Like Defects: The Role of Grain Boundary Crystallography Revealed by Experiment and Atomistic Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
Grain boundary triple junctions are an essential ingredient of the microstructure of polycrystalline materials. In this study, a triple junction is observed using atomic‐resolution scanning transmission electron microscopy and characterized. Computer simulations reveal that the junction has a dislocation character that is determined by the joining ...

La frontière, interface des trafics dans le Triangle d’or

open access: yesL'Espace Politique, 2015
From opiates to amphetamine-type stimulants, drug production and drug trafficking have evolved over a few decades in the so-called Golden Triangle, in the heart of the Indochinese peninsula’s fan-shaped highlands.

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

open access: yesAdvanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Modest Sociality: Continuities and Discontinuities

open access: yesJournal of Social Ontology, 2014
A central claim in Michael Bratman’s account of shared agency is that there need be no radical conceptual, metaphysical or normative discontinuity between robust forms of small-scale shared intentional agency, i.e., modest sociality, and individual ...

La frontière et son double. Un modèle à partir de l’expérience européenne

open access: yesBelgeo, 2013
From theoretical proposals and study of perceptions of boundaries and discontinuities in Europe by European and by those wishing to enter, the author proposes a model double border where local enclaves appear for compensating political boundaries ...

Transport Theorem for Spaces and Subspaces of Arbitrary Dimensions

open access: yesMathematics, 2020
Using the apparatus of traditional differential geometry, the transport theorem is derived for the general case of a M-dimensional domain moving in a N-dimensional space, M ≤ N .

Defect Evolution and Mechanical Performance of Fused Filament Fabrication‐Manufactured 17‐4PH Stainless Steel Revealed by X‐Ray Computed Tomography

open access: yesAdvanced Engineering Materials, EarlyView.
X‐ray computed tomography reveals how process‐induced defects evolve from green to sintered states in Fused Filament Fabrication (FFF)‐manufactured 17‐4PH stainless steel. Internal porosity, weakest cross‐sections, and fracture locations show strong correlation with tensile performance, demonstrating the potential of computed tomography (CT)‐based ...
