Toothsome Termites And Grilled Grasshoppers: A Cultural History Of Invertebrate Gastronomy, Deirdre P. Coleman Jun 2016

Toothsome Termites And Grilled Grasshoppers: A Cultural History Of Invertebrate Gastronomy, Deirdre P. Coleman

Animal Studies Journal

This article examines the recent turn to entomophagy (insect eating) as a new source of nutrition in a world confronted by increasing population, degraded soils, and food insecurity. Although many regard entomophagy with disgust, there is a case to be made that many insects are much more nutritious, as well as greener and cleaner¹, than many of the foods we regularly eat without thinking. Also, there is nothing new about insect eating or the belief in entomophagy as a sustainable and sensible practice. There is a long cultural history in countries such as Africa and Australia, for instance.


The Intersectional Influences Of Prince: A Human-Animal Tribute, Annie K. Potts Jun 2016

The Intersectional Influences Of Prince: A Human-Animal Tribute, Annie K. Potts

Animal Studies Journal

Prince Rogers Nelson (1958-2016) was best known for his joyful funk music and electrifying stage performances that transgressed normative representations of gender, sexuality, race, spirituality, identity and taste. He was also a compassionate person who held deep convictions about freedom and the right of all species to enjoy lives without fear and suffering. This essay discusses Prince’s intersectional influences – the various ways his virtuosity over the past 38 years disrupted binaries, challenged assumptions and stereotypes, advocated for social justice, and combatted speciesism in its many forms. Embedded within the essay are seven personal tributes written by fans of Prince ...


[Review] Ann C. Colley, Wild Animal Skins In Victorian Britain. Farnham: Ashgate, 2014, John Simons Jun 2016

[Review] Ann C. Colley, Wild Animal Skins In Victorian Britain. Farnham: Ashgate, 2014, John Simons

Animal Studies Journal

You should never judge a book by its cover but, of course, that’s exactly what the Victorians did when they looked at animals—or so Professor Ann Colley claims, and with some justification. This book is a contribution to the growing list of valuable and entertaining studies of the collection and exhibition of wild animals in Victorian Britain and beyond, and it is highly recommended to anyone researching the field. I was looking forward to reading this as although there has been a fair bit of work on zoos and menageries and, especially recently, on taxidermy, the habit of ...

Thirteen Figurings: Reflections On Termites, From Below, Perdita Phillips Jun 2016

Thirteen Figurings: Reflections On Termites, From Below, Perdita Phillips

Animal Studies Journal

This image essay is a creative reflection back upon The Encyclopaedia Isoptera: An encyclopaedia of the arts, sciences, literature and general information about termites, which was mostly written by the artist between 1997 and 1998, and forward to what termite art might undo today. Without access to living termites and, predating multispecies ethnographies, the Encyclopaedia Isoptera was an investigation into the limits of knowledge around termites. Looking back, it can be seen that certain strategies in the Encyclopaedia, such as looking at superseded or alternative knowledge, was a way of interrogating the boundaries of the sensible/insensible, and parallels more ...


Mimicry And Mimesis: Matrix Insect, Madeleine Kelly Jun 2016

Mimicry And Mimesis: Matrix Insect, Madeleine Kelly

Animal Studies Journal

Paintings and insects might seem like odd companions. In this paper I describe how a series of paintings I made depicting insects creates associations between mimesis and mimicry in order to flag a sort of protective self-referentiality – one where painting resists its proverbial ‘end’ and insects are presented as vital new orders. Drawing upon art historical references, such as Surrealism and the modernist grid, I argue that playing on these references and the compositional effects of camouflage enlivens our regard for the sensuous worlds of both insects and painting. I conclude by exploring how paintings of insects are powerful metaphors ...


Do Insects Feel Pain?, Helen Tiffin Jun 2016

Do Insects Feel Pain?, Helen Tiffin

Animal Studies Journal

This paper briefly considers the broad social and scientific background to research into the possibility of insects experiencing pain sensations analogous to our own. There has been increasing use of insects in pain experiments generally, as ethical constraints on the use of other animals increased through the last century. The ways in which scientists have tackled the question of insect pain, particularly in trying to distinguish between nociception and pain are then selectively summarised. These include opioid, hormonal, evolutionary, neurophysiological and behavioural approaches, as well as experiments designed to elucidate the difficult area of insect consciousness, from the 1980s to ...


A Sustainable Campus: The Sydney Declaration On Interspecies Sustainability, Fiona Probyn-Rapsey, Sue Donaldson, George Ioannides, Tess Lea, Kate Marsh, Astrida Neimanis, Annie Potts, Nik Taylor, Richard Twine, Dinesh Wadiwel, Stuart White Jun 2016

A Sustainable Campus: The Sydney Declaration On Interspecies Sustainability, Fiona Probyn-Rapsey, Sue Donaldson, George Ioannides, Tess Lea, Kate Marsh, Astrida Neimanis, Annie Potts, Nik Taylor, Richard Twine, Dinesh Wadiwel, Stuart White

Animal Studies Journal

Under the remit of an expanded definition of sustainability – one that acknowledges animal agriculture as a key carbon intensive industry, and one that includes interspecies ethics as an integral part of social justice – institutions such as Universities can and should play a role in supporting a wider agenda for sustainable food practices on campus. By drawing out clear connections between sustainability objectives on campus and the shift away from animal based products, the objective of this article is to advocate for a more consistent understanding and implementation of sustainability measures as championed by university campuses at large. We will draw ...


[Review] Robert Cribb, Helen Gilbert And Helen Tiffen, Wild Man From Borneo: A Cultural History Of The Orangutan. Honolulu: University Of Hawai’I Press, 2014, Matthew Chrulew Jun 2016

[Review] Robert Cribb, Helen Gilbert And Helen Tiffen, Wild Man From Borneo: A Cultural History Of The Orangutan. Honolulu: University Of Hawai’I Press, 2014, Matthew Chrulew

Animal Studies Journal

Wild Man from Borneo is a studious and wide-ranging cultural history of the orangutan and an indispensable resource for anyone working on this species or great apes in general. Orangutan stories and encounters have always captivated, from the tales of the Dayak and Batak peoples from Borneo and Indonesia, to the first rumours of early European travellers, and later observations and dissections. The orangutan’s uncanny similarity to humans, both in form and behaviour, made it central to a nineteenth-century debate about the uniqueness of humanity, in a time when few had been seen and Europeans were unsure just what ...


[Review] David Wilson, The Welfare Of Performing Animals: A Historical Perspective. Berlin: Springer, 2015, Peta Tait Jun 2016

[Review] David Wilson, The Welfare Of Performing Animals: A Historical Perspective. Berlin: Springer, 2015, Peta Tait

Animal Studies Journal

This book makes a valuable contribution to animal studies. It investigates the social and political processes concerned with the welfare of performing animals in Britain from the nineteenth century into the twentieth century. Although this area requires specialised inquiry, as David Wilson points out, animal performance is usually generalised about within pro-animal scholarship. Drawing on highly detailed research, this book provides a comprehensive account of the individuals and organisations that campaigned against animal performance and its cruelties and, in turn, those who campaigned for its continuation. It presents the human stories behind the movement against animal performance; descriptions of the ...


Provocations From The Field : The Place Of Bees, Michael R. Griffiths Jun 2016

Provocations From The Field : The Place Of Bees, Michael R. Griffiths

Animal Studies Journal

What would it mean to permit lack to become a productive place? What, indeed, would it mean to think place – so often feminized in the carnophallogocentric order – as active? Lack, in these terms, could be constitutive rather than a mere marker of absence. I propose that the place of bees in the symbolics of species could yield answers to these and related questions. Insects are often understood and conceived as communicators – through pheromones for instance. But in the very gesture that recognizes their communication, one finds the refusal of consciousness behind this communicative apparatus. If bees are said to lack ...


Humans, Insects And Their Interaction: A Multi-Faceted Analysis, Raynald H. Lemelin, Rick W. Harper, Jason Dampier, Robert Bowles, Debbie Balika Jun 2016

Humans, Insects And Their Interaction: A Multi-Faceted Analysis, Raynald H. Lemelin, Rick W. Harper, Jason Dampier, Robert Bowles, Debbie Balika

Animal Studies Journal

By administering Personal Meaning of Insects Maps (PMIM) to participants from eastern Canada and northeastern United States, we examine how people’s perceptions of insects are often determined by childhood encounters, corporeal cues, and influenced by environmental preference during recreational activities, often resulting in inconsistencies, inaccuracies, and bias. While the purpose of this study was to acquire a greater understanding of these entanglements through visual maps, the goal of this paper is to disentangle these morasses by highlighting the various positive, negative, dialectic, and ambivalent aspects of how insects are perceived.


Through The Eyes Of A Bee: Seeing The World As A Whole, Adrian G. Dyer, Scarlett R. Howard, Jair E. Garcia Jun 2016

Through The Eyes Of A Bee: Seeing The World As A Whole, Adrian G. Dyer, Scarlett R. Howard, Jair E. Garcia

Animal Studies Journal

Honeybees are an important model species for understanding animal vision as free-flying individuals can be easily trained by researchers to collect nutrition from novel visual stimuli and thus learn visual tasks. A leading question in animal vision is whether it is possible to perceive all information within a scene, or if only elemental cues are perceived driven by the visual system and supporting neural mechanisms. In human vision we often process the global content of a scene, and prefer such information to local elemental features. Here we discuss recent evidence from studies on honeybees which demonstrate a preference for global ...


Threshold Broadcast Encryption With Keyword Search, Shiwei Zhang, Yi Mu, Guomin Yang Jan 2016

Threshold Broadcast Encryption With Keyword Search, Shiwei Zhang, Yi Mu, Guomin Yang

Faculty of Engineering and Information Sciences - Papers: Part A

Many users store their data in a cloud, which might not be fully trusted, for the purpose of convenient data access and sharing. For efficiently accessing the stored data, keyword search can be performed by the cloud server remotely with a single query from the user. However, the cloud server cannot directly search the data if it is encrypted. One of solutions could be to allow the user to download the encrypted data, in order to carry out a search; however, it might consume huge network bandwidth. To solve this problem, the notion of keyword search on encrypted data (searchable ...


Joint Pet-Mr Respiratory Motion Models For Clinical Pet Motion Correction, Richard Manber, Kris Thielemans, Brian F. Hutton, Simon Wan, Jamie Mcclelland, Anna Barnes, Simon R. Arridge, Sebastien Ourselin, David Atkinson Jan 2016

Joint Pet-Mr Respiratory Motion Models For Clinical Pet Motion Correction, Richard Manber, Kris Thielemans, Brian F. Hutton, Simon Wan, Jamie Mcclelland, Anna Barnes, Simon R. Arridge, Sebastien Ourselin, David Atkinson

Faculty of Engineering and Information Sciences - Papers: Part A

Patient motion due to respiration can lead to artefacts and blurring in positron emission tomography (PET) images, in addition to quantification errors. The integration of PET with magnetic resonance (MR) imaging in PET-MR scanners provides complementary clinical information, and allows the use of high spatial resolution and high contrast MR images to monitor and correct motion-corrupted PET data. In this paper we build on previous work to form a methodology for respiratory motion correction of PET data, and show it can improve PET image quality whilst having minimal impact on clinical PET-MR protocols. We introduce a joint PET-MR motion model ...


Finite Time Singularities For The Locally Constrained Willmore Flow Of Surfaces, James A. Mccoy, Glen Wheeler Jan 2016

Finite Time Singularities For The Locally Constrained Willmore Flow Of Surfaces, James A. Mccoy, Glen Wheeler

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper we study the steepest descent L2-gradient flow of the functional Wλ1,λ2, which is the the sum of the Willmore energy, λ1-weighted surface area, and λ2-weighted enclosed volume, for surfaces immersed in R3. This coincides with the Helfrich functional with zero `spontaneous curvature'. Our first results are a concentration-compactness alternative and interior estimates for the flow. For initial data with small energy, we prove preservation of embeddedness, and by directly estimating the Euler-Lagrange operator from below in L2 we obtain that the maximal time of existence is finite. Combining this result with ...


Universal Measurability And The Hochschild Class Of The Chern Character, Alan L. Carey, Adam C. Rennie, F Sukochev, Dima Zanin Jan 2016

Universal Measurability And The Hochschild Class Of The Chern Character, Alan L. Carey, Adam C. Rennie, F Sukochev, Dima Zanin

Faculty of Engineering and Information Sciences - Papers: Part A

We study notions of measurability for singular traces, and characterise universal measurability for operators in Dixmier ideals. This measurability result is then applied to improve on the various proofs of Connes' identification of the Hochschild class of the Chern character of Dixmier summable spectral triples. The measurability results show that the identification of the Hochschild class is independent of the choice of singular trace. As a corollary we obtain strong information on the asymptotics of the eigenvalues of operators naturally associated to spectral triples (A, H, D) and Hochschild cycles for A.


A Magnetically Actuated Drug Delivery System For Robotic Endoscopic Capsules, Fredy Munoz, Gursel Alici, Weihua Li Jan 2016

A Magnetically Actuated Drug Delivery System For Robotic Endoscopic Capsules, Fredy Munoz, Gursel Alici, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part A

There is an increasing need to incorporate an actively controlled drug delivery system (DDS) into the next generation of capsule endoscopy in order to treat diseases in the gastrointestinal tract in a noninvasive way. Despite a number of attempts to magnetically actuate drug delivery mechanisms embedded in endoscopic capsules, longer operating distances and further miniaturization of on-board components are still drawbacks of such systems. In this paper, we propose an innovative magnetic system that consists of an array of magnets, which activates a DDS, based on an overly miniaturized slider-crank mechanism. We use analytical models to compare the magnetic fields ...


Subject-Adaptive Integration Of Multiple Sice Brain Networks With Different Sparsity, Jianjia Zhang, Luping Zhou, Lei Wang Jan 2016

Subject-Adaptive Integration Of Multiple Sice Brain Networks With Different Sparsity, Jianjia Zhang, Luping Zhou, Lei Wang

Faculty of Engineering and Information Sciences - Papers: Part A

As a principled method for partial correlation estimation, sparse inverse covariance estimation (SICE) has been employed to model brain connectivity networks, which holds great promise for brain disease diagnosis. For each subject, the SICE method naturally leads to a set of connectivity networks with various sparsity. However, existing methods usually select a single network from them for classification and the discriminative power of this set of networks has not been fully exploited. This paper argues that the connectivity networks at different sparsity levels present complementary connectivity patterns and therefore they should be jointly considered to achieve high classification performance.In ...


Image Descriptors From Convnets: Comparing Global Pooling Methods For Image Retrieval, Ian Comor, Yan Zhao, Zhimin Gao, Luping Zhou, Lei Wang Jan 2016

Image Descriptors From Convnets: Comparing Global Pooling Methods For Image Retrieval, Ian Comor, Yan Zhao, Zhimin Gao, Luping Zhou, Lei Wang

Faculty of Engineering and Information Sciences - Papers: Part A

2016 IEEE.A major component of a generic image retrieval pipeline is producing concise and effective descriptors for each image. Previous works have shown impressive results in image retrieval when using descriptors from the black-box output of the fully-connected stage of pretrained Convolutional Neural Networks (ConvNets). However, previous work on descriptors pooled from the deep feature maps from late convolutional layers can produce more discriminative descriptors for generic image retrieval, while being relatively concise. When planning to globally pool such feature maps from a ConvNet, some options to consider are (1) the depth of the network, (2) choice of layer ...


Effect Of Mineral Matter On The Reactivity Of Coke And Its Replication In A Coke Analogue, Raymond Longbottom, Brian J. Monaghan, Azrin A. Chowdhury, Mark H. Reid, Guangqing Zhang, Merrick R. Mahoney, Kim Hockings Jan 2016

Effect Of Mineral Matter On The Reactivity Of Coke And Its Replication In A Coke Analogue, Raymond Longbottom, Brian J. Monaghan, Azrin A. Chowdhury, Mark H. Reid, Guangqing Zhang, Merrick R. Mahoney, Kim Hockings

Faculty of Engineering and Information Sciences - Papers: Part A

The reactivity of coke analogues doped with minerals to mimic the mineralogy of specific industrial cokes was compared with the reactivity of the industrial cokes. The reactivity was assessed in a pseudo-CRI type test. This involved reacting the carbonaceous materials (analogue and industrial coke) in CO2 at 1 100°C in a thermos-gravimetric system. In this comparison, the mineral matter added to the coke analogue was prepared from ashing of the industrial cokes. A distinct ranking of reactivity for the industrial cokes was determined to be coke A < coke B < coke C. The high reactivity of coke C was attributed to the high iron content in its ash. The higher reactivity of coke B over coke A was attributed to its higher porosity and lower rank (of the original coal carbon type) of the industrial cokes. The coke analogue replicated the increased reactivity of coke C over cokes A and B, indicating that the coke analogue is able to some extent to replicate the effect of coke mineralogy on coke reactivity in CO2. The use of the coke analogue allowed assessment of the difference in the reactivities of cokes A and B. When porosity and carbon type were fixed by use of the analogue, the reactivities of the analogues of cokes A and B were found to be similar.


Comprehensive Performance Analysis Of Fully Cooperative Communication In Wbans, Le Chung Tran, Alfred Mertins, Xiaojing Huang, Farzad Safaei Jan 2016

Comprehensive Performance Analysis Of Fully Cooperative Communication In Wbans, Le Chung Tran, Alfred Mertins, Xiaojing Huang, Farzad Safaei

Faculty of Engineering and Information Sciences - Papers: Part A

While relay-based cooperative networks (widely known in the literature as cooperative communication), where relays only forward signals from the sources to the destination, have been extensively researched, fully cooperative systems have not been thoroughly examined. Unlike relay networks, in a fully cooperative network, each node acts as both a source node sending its own data and a relay forwarding its partner's data to the destination. Mutual cooperation between neighboring nodes is believed to improve the overall system error performance, especially when space-time codes are incorporated. However, a comprehensive performance analysis of space-time-coded fully cooperative communication from all three perspectives ...


Video Enhanced Multiple Choice Questions - Personalising Elearning, Nadine Adams, Anne L. Porter Jan 2016

Video Enhanced Multiple Choice Questions - Personalising Elearning, Nadine Adams, Anne L. Porter

Faculty of Engineering and Information Sciences - Papers: Part A

Instructional videos have been successfully used to teach mathematical concepts to distance students. These videos allow the students to see and hear their lecturer with an added advantage of being able to stop and rewind or replay until the concept is understood. While videos facilitate student understanding, formative assessment provides both lecturer and student with an indication of the latter's mastery of a mathematical concept. Formative assessment with handwritten feedback is viewed as preferential because changing university culture means few academics have the time to provide comprehensive handwritten feedback to large numbers of students for every concept. Further, for ...


Performance Analysis Of A Magnetorheological Damper With Energy Harvesting Ability, Guoliang Hu, Yun Lu, Shuaishuai Sun, Weihua Li Jan 2016

Performance Analysis Of A Magnetorheological Damper With Energy Harvesting Ability, Guoliang Hu, Yun Lu, Shuaishuai Sun, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part A

A magnetorheological (MR) damper with energy harvesting ability was proposed based on electromagnetic induction (EMI) principle. The energy harvesting part was composed of a permanent magnet array and inducing coils which move vertically. This device could act as a linear power generator when the external excitation was applied, and the kinetic energy could be converted into electrical energy due to the relative linear motion between the magnets array and the inducing coils. Finite element models of both the MR damper part and the linear power generator part were built up separately to address the magnetic flux distributions, the magnetic flux ...


Visualisation For Large-Scale Gaussian Updates, Jonathon Rougier, Andrew Zammit-Mangion Jan 2016

Visualisation For Large-Scale Gaussian Updates, Jonathon Rougier, Andrew Zammit-Mangion

Faculty of Engineering and Information Sciences - Papers: Part A

In geostatistics and also in other applications in science and engineering, it is now common to perform updates on Gaussian process models with many thousands or even millions of components. These large-scale inferences involve modelling, representational and computational challenges. We describe a visualization tool for large-scale Gaussian updates, the 'medal plot'. The medal plot shows the updated uncertainty at each observation location and also summarizes the sharing of information across observations, as a proxy for the sharing of information across the state vector (or latent process). As such, it reflects characteristics of both the observations and the statistical model.We ...


Kinematical Limit Analysis For A Slope Reinforced With One Row Of Stabilizing Piles, Shiguo Xiao, Hong He, Jinxiu Zeng Jan 2016

Kinematical Limit Analysis For A Slope Reinforced With One Row Of Stabilizing Piles, Shiguo Xiao, Hong He, Jinxiu Zeng

Faculty of Engineering and Information Sciences - Papers: Part A

Stabilizing piles are commonly used to improve slope stability. The load that a pile should sustain and the associated slip surface under a prescribed factor of safety are two critical design parameters in practice. Based on the kinematically admissible failure mechanism, a limit analysis approach is introduced, which considers two potential slip surfaces that individually lie in the upslope and downslope of the piles. The explicit formulas for the upslope thrust force and downslope resistance on a pile are derived, which enables the calculation of the maximum load on a pile and the corresponding critical slip surfaces using a computer ...


Evaluation Methodology And Implementation For Natural Ventilation Control Strategies, Massimo Fiorentini, Georgios Kokogiannakis, Warwick Jackson, Zhenjun Ma, Paul Cooper Jan 2016

Evaluation Methodology And Implementation For Natural Ventilation Control Strategies, Massimo Fiorentini, Georgios Kokogiannakis, Warwick Jackson, Zhenjun Ma, Paul Cooper

Faculty of Engineering and Information Sciences - Papers: Part A

This paper describes a methodology for evaluating the effectiveness of various control strategies for the operation of window actuators to control the indoor climate, and their implementation in a full scale case study building. In this study, the effectiveness of a control strategy is considered in terms of the capability of the controller for maintaining the indoor thermal comfort in a prescribed variable range, and its effect on the minimisation of the operational energy consumption of the building, due to a lower thermal energy demand to be met by the heating and cooling system. A model of the case study ...


Building A Microsimulation Model Of Heroin Use Careers In Australia, Alison Ritter, Nagesh Shukla, Marian D. Shanahan, Van Hoang Phuong, Vu Lam Cao, Pascal Perez, Michael P. Farrell Jan 2016

Building A Microsimulation Model Of Heroin Use Careers In Australia, Alison Ritter, Nagesh Shukla, Marian D. Shanahan, Van Hoang Phuong, Vu Lam Cao, Pascal Perez, Michael P. Farrell

Faculty of Engineering and Information Sciences - Papers: Part A

Illicit heroin use is a worldwide problem, with significant health and social costs. Treatment is known to be effective in changing heroin use habits, but it often needs to be provided over a lifetime, with people cycling in and out of treatment. It is therefore important to capture a long-term perspective on heroin use careers. The aim of this project was to build a lifetime microsimulation model of heroin using careers. This paper describes the conceptual logic of the model, the input parameters and the verification and validation results. A microsimulation model was chosen as the most appropriate simulation platform ...


Interaction Prediction Between Groundwater And Quarry Extension Using Discrete Choice Models And Artificial Neural Networks, Johan Barthelemy, Timoteo Carletti, Louise Collier, Vincent Hallet, Marie Moriame, Annick Sartenear Jan 2016

Interaction Prediction Between Groundwater And Quarry Extension Using Discrete Choice Models And Artificial Neural Networks, Johan Barthelemy, Timoteo Carletti, Louise Collier, Vincent Hallet, Marie Moriame, Annick Sartenear

Faculty of Engineering and Information Sciences - Papers: Part A

Groundwater and rock are intensively exploited in the world. When a quarry is deepened the water table of the exploited geological formation might be reached. A dewatering system is therefore installed so that the quarry activities can continue, possibly impacting the nearby water catchments. In order to recommend an adequate feasibility study before deepening a quarry, we propose two interaction indices between extractive activity and groundwater resources based on hazard and vulnerability parameters used in the assessment of natural hazards. The levels of each index (low, medium, high, very high) correspond to the potential impact of the quarry on the ...


Residual Stress Study Of Al/Al Laminates Processed By Accumulative Roll Bonding, Lihong Su, Cheng Lu, Hui Jun Li, Vladimir Luzin, Hui Wang, Anh Kiet Tieu Jan 2016

Residual Stress Study Of Al/Al Laminates Processed By Accumulative Roll Bonding, Lihong Su, Cheng Lu, Hui Jun Li, Vladimir Luzin, Hui Wang, Anh Kiet Tieu

Faculty of Engineering and Information Sciences - Papers: Part A

In this work accumulative roll bonding (ARB) was used to combine AA1050 and AA6061 sheets to produce AA1050/AA1050, AA6061/AA6061 and AA1050/AA6061 laminates with ultrafine grained (UFG) structure. Two sheets of starting materials were roll bonded with 200 °C preheating for 180 s before rolling. The through-thickness residual stress distribution of these laminates processed up to two cycles of ARB was determined by neutron diffraction with spatial resolution of 0.2 mm through 1.5 mm thickness. The measurements also required high accuracy of only few MPa since residual stresses in the laminates peaked at only about 15 ...
