Improved particle separation, characterisation and analysis for ore beneficiation studies using 3D X-ray micro-computed tomography Open

Yulai Zhang, Nicolas François, Lachlan Deakin, Aleese Barron, Cathy Evans , et al. · 2024

In mineral processing, ore materials exist in the form of particles of various sizes. Being able to determine particle properties and population statistics is central to the efficient beneficiation of ore materials. X-ray µCT imaging is a …

The 15 January 2022 Hunga (Tonga) eruption: A gas-driven climactic explosion Open

Richard W. Henley, Cornel E.J. de Ronde, Richard Arculus, Graham Hughes, Thanh‐Son Phạm , et al. · 2024

An extraordinarily powerful, explosive eruption occurred from Hunga volcano in the Tonga island arc on 15 January 2022 and generated an eruption column 58 km high. The explosive eruption also generated atmospheric gravity waves, extreme ru…

Improved 3d Particle Separation, Characterisation and Analysis for Ore Beneficiation Studies Open

In-situ study of texture-breakage coupling in a copper ore using X-ray micro-CT Open

Yulai Zhang, Nicolas François, Richard W. Henley, Lydia Knuefing, Michael L. Turner , et al. · 2023

As the mining industry continues to seek greater energy efficiency, it needs more effective characterization of ore material as it progresses from mine to mill. The energy cost of ore mineral liberation, for example, is critically dependen…

Sulphide Globules in a Porcellanite–Buchite Composite Xenolith from Stromboli Volcano (Aeolian Islands, Southern Italy): Products of Open-System Igneous Pyrometamorphism Open

Alberto Renzulli, Marco Taussi, Frank Brink, Stefano Del Moro, Richard W. Henley · 2021

Pyrometamorphism is the highest temperature end-member of the sanidinite facies (high-temperature, low-pressure contact metamorphism) and comprises both subsolidus and partial melting reactions which may locally lead to cryptocrystalline-g…

Sulfur sequestration, redox control and metallogeny in Earth and other planetary volcanic systems Open

Tobias P. Fischer, Richard W. Henley · 2021

Prograde and retrograde metasomatic reactions in mineralised magnesium-silicate skarn in the Cu-Au Ertsberg East Skarn System, Ertsberg, Papua Province, Indonesia Open

Melanie J. Sieber, Frank Brink, Clyde Leys, P. L. King, Richard W. Henley · 2020

High resolution 3D mapping of grain kinematics during high temperature sequestration of SO2 from flue gas by carbonate aggregates Open

Greenhouse Ventilation Open

Jonathan Adam Watson, Celina Gómez, D. E. Buffington, R. A. Bucklin, Richard W. Henley , et al. · 2019

Greenhouse ventilation involves removing air from inside the greenhouse and replacing it with outside air. The ventilation may be natural (caused by wind and temperature forces) or mechanical (accomplished by using fans). The purposes of v…

Heating Greenhouses Open

Jonathan Adam Watson, Celina Gómez, D. E. Buffington, R. A. Bucklin, Richard W. Henley , et al. · 2019

A greenhouse has one purpose: to provide and maintain the environment that will result in optimum crop production for maximum profit. This includes an environment for work efficiency as well as for crop growth. This publication is limited …

Functional Metrics in Axiomatic Design Open

Richard W. Henley · 2018

The objective of this work is to study, functional metrics (FMs) in Axiomatic Design (Suh 1990), their relationship to each other within the functional domain, and understand ways in which they add value to the design process and the desig…

Maintenance Guide for Greenhouse Ventilation, Evaporative Cooling Heating Systems Open

D. E. Buffington, R. A. Bucklin, Richard W. Henley, Dennis B. McConnell · 2018

Heating, cooling and ventilation are three main environmental control methods to maintain the desired growing environments. Regular maintenance of the equipment is the key to an effective performance. Any small changes or a minor downtime …

SO 2 flux and the thermal power of volcanic eruptions Open

Richard W. Henley, Graham Hughes · 2016

Sulfur isotope and trace element systematics of zoned pyrite crystals from the El Indio Au–Cu–Ag deposit, Chile Open

Dominique Tanner, Richard W. Henley, John Mavrogenes, Peter Holden · 2016

We present a comparative study between early, massive pyrite preceding (Cu–Ag) sulfosalt mineralization in high-temperature feeder zones (‘early pyrite’) and late pyrite that formed during silicic alteration associated with Au deposition (…

Axiomatic Design Applied to Play Calling in American Football Open

Richard W. Henley, Christopher Brown · 2016

The objective of this paper is to learn if the use of functional metrics and the use of parent-child equations can guide design decompositions for winning games. This study is performed in the context of designing play calling strategies i…

Metrics for Developing Functional Requirements and Selecting Design Parameters in Axiomatic Design Open

Christopher Brown, Richard W. Henley · 2016

This work studies the systematic use of metrics for developing design decompositions in axiomatic design (AD). The supposition is that a rigorous use of metrics will guide the formulation of superior functional requirements (FRs), and the …

Using Functional Metrics to Facilitate Designing Collectively Exhaustive Mutually Exclusive Systems in the Context of Managing Return on Investment Open

Richard W. Henley · 2015

The objective of this paper is to test two hypotheses in the context of managing return on investment (ROI): (1) that a meaningful functional metric (FM) assigned to every functional requirement could facilitate the design of collectively …
