Characterization of renewable reductants and charcoal-based pellets for the use in ferroalloy industries
(Elsevier, 2018-11-05)This study investigates the effect of high-temperature pyrolysis and post-treatment processes on spruce and oak charcoal yields and CO2 reactivity in a slow pyrolysis reactor. Post-treatment processes such as co-pyrolysis ... -
Removal of phenol and chlorine from wastewater using steam activated biomass soot and tire carbon black
(Elsevier, 2018-10-30)This study aims to demonstrate a novel method for removing toxic chemicals using soot produced from wood and herbaceous biomass pyrolyzed in a drop tube reactor and tire pyrolytic carbon black. The influence of ash content, ... -
Conservation voltage reduction in secondary distribution networks with distributed generation and electric vehicle charging loads
(IEEE, 2018-08-23)This paper investigates the potential for Conservation Voltage Reduction (CVR) in Low Voltage (LV) secondary distribution networks. CVR is a well-established technique where the voltage in LV networks is managed at a ... -
Empowering learners with self-selecting learning tools
(International Academy of Technology, Education and Development (IATED), 2018-03-05)Students need to be encouraged while in the liminal space i.e. the learning journey in the process of mastering a threshold concept (Land et al, 2014) (Meyer & Land, 2003). However, this learning journey can either be a ... -
Evolving collective behaviours in simulated kilobots
(Association for Computing Machinery, 2018-04-09)The field of Evolutionary Robotics has multiple common tasks and widely used benchmark activities such as navigation, obstacle avoidance, and phototaxis. We present an evolutionary approach to learning behaviours that ... -
An evaluation of the general composition and critical raw material content of bauxite residue in a storage area over a twelve-year period
(Elsevier, 2018-10-09)Bauxite residue, the by-product produced in the alumina industry, is being produced at an estimated global rate of approximately 150 million tonnes per annum. Currently, the reuse of bauxite residue is low (∼2%), due to ... -
Re-boot learning: providing an e-tivity scaffold for engagement for early research activity through blog technology embedded within teaching and learning
(International Academy of Technology, Education and Development (IATED), 2018-03-05)Increasing student numbers in higher education over the last decade has challenged educational environments. The challenge for educators is to re-think learning environments and delivery methods such that a student-educator ... -
Investigation of the mechanical interaction of the trabecular core with an external shell using rapid prototype and finite element models
(Elsevier, 2009-04-05)The mechanical properties of vertebral bone have been widely studied with the ultimate goal of improving fracture risk prediction. However, the mechanical interaction between the cortical shell and the trabecular core is ... -
Changes in the fractionation profile of Al, Ni and Mo during bioleaching of spent hydroprocessing catalysts with Acidithiobacillus ferrooxidans.
(Taylor & Francis, 2018-06-05)Spent hydroprocessing catalysts are known to contain a variety of potentially toxic metals and therefore studies on the bioavailability and mobility of these metals are critical for understanding the possible environmental ... -
Smartphones, biometrics, and a brave new world
(Institute of Electrical and Electronics Engineers (IEEE), 2016-09-09)In this article, we take a somewhat contrarian viewpoint - that biometrics may, in fact, offer solutions to many of today's cyber-security problems that appear with increasing frequency in prime-time news. This outcome ... -
Smart augmentation learning an optimal data augmentation strategy
(Institute of Electrical and Electronics Engineers (IEEE), 2017-04-24)A recurring problem faced when training neural networks is that there is typically not enough data to maximize the generalization capability of deep neural networks. There are many techniques to address this, including ... -
Semiparallel deep neural network hybrid architecture: first application on depth from monocular camera
(Society of Photo-optical Instrumentation Engineers (SPIE), 2018-08-07)Deep neural networks have been applied to a wide range of problems in recent years. Convolutional neural network is applied to the problem of determining the depth from a single camera image (monocular depth). Eight different ... -
Unconstrained palmprint as a smartphone biometric
(IEEE, 2017-11-13)In this work the use of palmprints as an alternative biometric for smartphones is investigated and its feasibility is evaluated across multiple devices using unconstrained acquisition. A novel multi-device database that ... -
Pushing the AI envelope: merging deep networks to accelerate edge artificial intelligence in consumer electronics devices and systems
(IEEE, 2018-02-08)Deep neural networks (DNNs) are widely used by both academic and industry researchers to solve many long-standing problems in machine learning. There has been such a growth of research in this field, and it has been applied ... -
Application of preconditioned alternating direction method of multipliers in depth from focal stack
(Society of Photo-optical Instrumentation Engineers (SPIE), 2018-04-06)Postcapture refocusing effect in smartphone cameras is achievable using focal stacks. However, the accuracy of this effect is totally dependent on the combination of the depth layers in the stack. The accuracy of the ... -
Total variation-based dense depth from multicamera array
(Society of Photo-optical Instrumentation Engineers (SPIE), 2018-05-20)Multicamera arrays are increasingly employed in both consumer and industrial applications, and various passive techniques are documented to estimate depth from such camera arrays. Current depth estimation methods provide ... -
