Extra Specialist Seminars:Monday 10 June 2019 - Joe Kelleher EnginX - part of the CCPi Working Group meeting: video conference event ‘Neutron diffraction and imaging on Engin-X for multi-scale characterisation’. Abstract: Characterisation and analysis of engineering structures from the atomic up to the macroscale is often needed for a full understanding of their behaviour. Neutrons are a versatile probe for such characterisation, as the wavelengths of neutrons needed for diffraction from common crystalline materials can easily achieve penetrations of several centimetres in common engineering materials. Here, we show examples of engineering research on the Engin-X instrument at the ISIS Pulsed Neutron Source, while also demonstrating how these may be combined with complementary measurements on other instruments.*8 March 2018* Manchester Inverse Imaging Goup Seminar: Alan Turing Building, Frank Adams 2 at 2pm Prof Bill Lionheart "Histotomography" |

Training Diamond Manchester Collaboration, CCPi and HIP, the University of Manchester and Diamond Light Source will be running a 2 day course on the Visualisation and quantification of tomographic data. The course will be based both around open-source software (ImageJ) and commercial software AVIZO Software course. This is the fourth training course of this kind to be offered by the Diamond Manchester Collaboration and will be on the 16th and 17th of April 2015 at Diamond Light Source. The course will consist of a lecture and hands-on exercises intended for new or existing users of Avizo software. Attendee capacity for the training is limited to 25 so if you are interested please register with me at your earliest opportunity. As we are also training future trainers, people volunteering to help in future courses will be given priority. |

< < | 14 May 2019: Wen Zhang Title: Investigation of fatigue overload retardation mechanisms in Ni as a function of grain size Abstract: Overload fatigue test results are presented for high purity nickel with grain sizes ranging from micrometres down to nanometres. Synchrotron X-ray diffraction (SXRD) and digital image correlation (DIC) were applied in situ to map the through-thickness strain field and surface displacement field respectively before, during and after overload. The variation in residual stress and stress intensity factor (SIF) was evaluated from the diffraction strain field while the changes of crack length, crack opening displacement and SIF range were determined from the DIC displacement field. Retardation was observed for all the samples at low stress ratio (R=0.1). The fatigue crack growth (FCG) for the microcrystalline sample (grain size greater than 1 µm) was the most retarded after overload because of its more tortuous and rougher crack surface, larger overload plastic zone and hence more significant crack face contact. While for the nanocrystalline sample (grain size below 100 nm) the FCG was least affected by overload due to the relatively straight and flat crack surface, very small plastic zone size and therefore limited residual stress and no evident crack closure. The decrease in FCG for ultrafine grained (UFG) nickel (with grain size between 1 µm and 100 nm) is not only resulted from overload-induced residual stress and crack closure, but also the crack deflection caused by the anisotropic microstructure. More significant residual stress and crack closure were observed for the UFG sample with elongated microstructure aligned perpendicular to the crack propagation direction. and Katrine Bangsgaard Title TBA | |||||||

The variation in residual stress and stress intensity factor (SIF) was evaluated from the diffraction strain field while the changes of crack length, crack opening displacement and SIF range were determined from the DIC displacement field. Retardation was observed for all the samples at low stress ratio (R=0.1). The fatigue crack growth (FCG) for the microcrystalline sample (grain size greater than 1 µm) was the most retarded after overload because of its more tortuous and rougher crack surface, larger overload plastic zone and hence more significant crack face contact. While for the nanocrystalline sample (grain size below 100 nm) the FCG was least affected by overload due to the relatively straight and flat crack surface, very small plastic zone size and therefore limited residual stress and no evident crack closure. The decrease in FCG for ultrafine grained (UFG) nickel (with grain size between 1 µm and 100 nm) is not only resulted from overload-induced residual stress and crack closure, but also the crack deflection caused by the anisotropic microstructure. More significant residual stress and crack closure were observed for the UFG sample with elongated microstructure aligned perpendicular to the crack propagation direction. | ||||||||

"Tomographic imaging using intense laser-driven radiation sources": High power lasers (> 100 TW) can be used as the driver for compact light sources that deliver extreme brightness ultrashort x-ray pulses ideally suited for advanced imaging applications. The laser is used to create a cm-scale plasma accelerator generating femtosecond relativistic electron bunches with GeV? energy that can be converted to x-ray beams through a plasma betatron process or bremsstrahlung radiation. This produces up to 1010 photons per pulse in the x-ray region spanning 10 keV up to multi-MeV. The beam is spatially coherent because of the micron-scale source size, enabling phase enhanced imaging to improve contrast between low Z materials with similar density. Using the Gemini laser at RAL we have demonstrated high resolution micro-CT of biological samples and NDE of industrial components. The same laser can generate x-ray energies in the 10’s keV range for soft tissue, low density polymer and composite materials and in the multi-MeV range for penetration of large dense samples such as automotive or aerospace components. Commercialisation of high power laser technology has led to robust, well-characterised systems that are relatively compact and affordable. In the next few years, we expect to develop laser-plasma accelerators as dedicated x-ray machines, capable of micron resolution tomography with high frame rate. This shift from conducting proof-of-principle experiments to operating a synchrotron-style beam brings challenges for our research community – it is necessary for us to build expertise in handling large datasets, image processing, and tomographic reconstruction. We will present the status of CT using laser-driven sources with a view to discussion of how we can engage with the imaging community and what new opportunities may arise for the CCPi network.dimensional-XCT conference update from Huddersfield, Paul Bills A Hartree Perspective: Working with STFC Opportunities - Tim Kirkham (12:45pm) The Bridging for Innovators https://www.stfc.ac.uk/b4iIntroduction new staff and description of ICT'2019, Gemma Fardell ...presenting her experiences to data including work at Nikon Metrolgy and plans for the future - also review of iCT ...'very application heavy this year.

Abstract: Imaging techniques play an important role in several research fields: medicine, biology, material science, geosciences and archaeology. Optical and scanning electron microscopy techniques are widely adopted tools for the investigation of the texture and morphology in a large range of materials. Imaging techniques based on hard X-ray are also of particular interest and microradiography has proved to be useful for clinical diagnostics and for the investigation of crystal growth. | ||||||||

< < | In recent years great interest has been posed on X-ray computed microtomography (microCT) techniques, employing microfocus and synchrotron radiation sources. These techniques produce three-dimensional (3D) or 4D (dynamic microCT) images of the internal structure of objects with a spatial resolution at the micron- and submicron- scale. Investigations performed directly in the 3D domain overcome the limitations of stereological methods usually applied to microscopy-based analyses and a non-destructive approach is more suitable for further complementary analyses and for precious or unique samples (fossils and archeological finds, in-vivo and in-situ imaging, etc …). | |||||||

An intriguing challenge is to extract directly from 3D and 4D images quantitative parameters related to the physical properties of the studied materials. Porosity and specific surface area as well as anisotropy, connectivity and tortuosity are interesting descriptors of a 3D model. However, accurate image processing and analysis methods for an effective assessment of these parameters are still an open issue in several applications. | ||||||||

< < | 6 July 2016, 2:00pm-3:00pm at RAL AND 11 July 2016 at DL SCD Seminar: Dave Pugmire (Oak Ridge National Laboratory), "Visualization and Analysis Services for Extreme Scale Supercomputers" The scientific data that are being generated today, and in the near future, will quickly outpace our ability to process and understand it. The data generated are growing in multiple ways, including the size of the data, the rate at which it arrives, and the varying types of data. Additionally, data are available from multiple sources, including for example, computational simulations and sensor data extracted from experiments. In such situations, workflows for the movement and management of data, as well as the analysis and visualization while the data are in transit, become even more critical, and increasingly challenging. At the same time, revolutionary changes are emerging in the architectures of supercomputers. These changes include tremendous increases in concurrency on each node, as well as a deep hierarchy of memory. These architectures are a challenge for currently running HPC codes, as well as visualization and analysis algorithms. We are, along with collaborators at other national laboratories, and universities, researching and developing a cohesive framework that will enable scientists to manage the growing data problem, and to enable them to extract knowledge and insight. Central to this work is a “Service Oriented Architectures” (SOA) framework that provides a clear separation from the data producers and consumers. Our framework is based on the ADIOS middleware layer, that manages the data as they are produced, and orchestrates movement through the deep memory hierarchy. The data consumers, in this case visualization and analysis services built from tools like VisIt, ParaView, VTK-m, and pbdR, will interact with the middleware layer for access to data, and for coordination to optimize access across the deep memory hierarchy. These services, which will be self-consistent, interoperable operations will enable scientists to construct multiple complex workflows. This talk will present the preliminary research on the development of this framework and the associated services as well as the initial results obtained working with several large-scale simulation codes running on the Titan supercomputer at ORNL. And finally, a detailed discussion on the future research plans and directions that will enable scientific insight on exascale computing systems. | |||||||

< < | Abstract: The Harwell Imaging Partnership (HIP) was established to promote industrial engagement with STFC large facilities by fostering interactions between industrial researchers, STFC facility scientists and university research groups. In this context, “imaging” includes microscopy, tomography, and ‘functional imaging’, in which properties of complex structures are mapped with high spatial resolution using X-rays, neutrons or lasers. SCD is being considered actively as a ‘facility’ in its own right in this context. A set of case studies based on data transfer, portal interaction, remote access including computation, as well as visualisation specialisms have all been added to the HIP portfolio. This introductory short session will cover some of the opportunities available by working with the HIP as well as future proposed new centre interactions. | |||||||

"Tomographic imaging using intense laser-driven radiation sources": High power lasers (> 100 TW) can be used as the driver for compact light sources that deliver extreme brightness ultrashort x-ray pulses ideally suited for advanced imaging applications. The laser is used to create a cm-scale plasma accelerator generating femtosecond relativistic electron bunches with GeV? energy that can be converted to x-ray beams through a plasma betatron process or bremsstrahlung radiation. This produces up to 1010 photons per pulse in the x-ray region spanning 10 keV up to multi-MeV. The beam is spatially coherent because of the micron-scale source size, enabling phase enhanced imaging to improve contrast between low Z materials with similar density. Using the Gemini laser at RAL we have demonstrated high resolution micro-CT of biological samples and NDE of industrial components. The same laser can generate x-ray energies in the 10’s keV range for soft tissue, low density polymer and composite materials and in the multi-MeV range for penetration of large dense samples such as automotive or aerospace components. Commercialisation of high power laser technology has led to robust, well-characterised systems that are relatively compact and affordable. In the next few years, we expect to develop laser-plasma accelerators as dedicated x-ray machines, capable of micron resolution tomography with high frame rate. This shift from conducting proof-of-principle experiments to operating a synchrotron-style beam brings challenges for our research community – it is necessary for us to build expertise in handling large datasets, image processing, and tomographic reconstruction. We will present the status of CT using laser-driven sources with a view to discussion of how we can engage with the imaging community and what new opportunities may arise for the CCPi network. | ||||||||

Every other year it is based in Wels, and ... little more research orientated. The industry talks only take up one morning, and there was a lot of input from research groups around Europe. This year ~350 attendees, so the conference is probably the largest XCT one in Europe - there were a couple of posters on multi-spectral CT, and reconstruction is always a popular topic." | |||||||

< < | Abstract; "SuRVoS brings together machine learning models, computer vision techniques and human knowledge within a user interface to interactively segment large 3D volumes. The user interface of SuRVoS is divided in two panels. One panel contains all the available plugins (or tools) and the other panel, instead, resides the visualisation panel (where everything made with SuRVoS will be visualised) and another two main workflows. SuRVoS is able to work with very large datasets by means of its Region Of Interest (ROI) system and a HDF5 workspace. Everything loaded with SuRVoS and every action made within it will be saved in a workspace folder inside an HDF5 file. HDF5 is an on-disk data format that loads only the required data on memory. By using ROIs, SuRVoS limits all its actions to the selected ROI, which allows the user to load large datasets but operate only in small windows, also improving the performance of all the subsequent actions." | |||||||

Abstract: Imaging techniques play an important role in several research fields: medicine, biology, material science, geosciences and archaeology. Optical and scanning electron microscopy techniques are widely adopted tools for the investigation of the texture and morphology in a large range of materials. Imaging techniques based on hard X-ray are also of particular interest and microradiography has proved to be useful for clinical diagnostics and for the investigation of crystal growth. |

Optical and scanning electron microscopy techniques are widely adopted tools for the investigation of the texture and morphology in a large range of materials. Imaging techniques based on hard X-ray are also of particular interest and microradiography has proved to be useful for clinical diagnostics and for the investigation of crystal growth. In recent years great interest has been posed on X-ray computed microtomography (microCT) techniques, employing microfocus and synchrotron radiation sources. These techniques produce three-dimensional (3D) or 4D (dynamic microCT) images of the internal structure of objects with a spatial resolution at the micron- and submicron- scale. Investigations performed directly in the 3D domain overcome the limitations of stereological methods usually applied to microscopy-based analyses and a non-destructive approach is more suitable for further complementary analyses and for precious or unique samples (fossils and archeological finds, in-vivo and in-situ imaging, etc …). An intriguing challenge is to extract directly from 3D and 4D images quantitative parameters related to the physical properties of the studied materials. Porosity and specific surface area as well as anisotropy, connectivity and tortuosity are interesting descriptors of a 3D model. However, accurate image processing and analysis methods for an effective assessment of these parameters are still an open issue in several applications. Several scientific applications of advanced hard X-ray imaging techniques will be presented in this seminar, focusing our attention in the field of geomaterials. Examples of results obtained from the 3D morphological and textural characterization of crystals and pores in volcanic products, reservoir rocks as well as cement-based materials will be illustrated. | |||||||

The Tomviz project builds upon a number of open source frameworks to deliver a powerful desktop application for research, leveraging the Python environment along with a number of scientific Python modules to deliver a comprehensive solution for materials tomography at nanoscale to atomic resolution. The development of the application will be discussed, along with the Pythonbased data processing pipeline, and the XML format used to enable complex, reproducible data processing and visualization pipelines. The application is based on Qt, VTK, ParaView, and ITK with a bundled Python distribution making use of NumPy, SciPy, and Python wrapped ITK/ParaView to offer a powerful visualization and data analysis application. The development, packaging, and deployment of a robust, crossplatform application for materials tomography will be discussed. The current state of reproducible analysis and data processing pipelines demonstrated, and future directions will be discussed. The use of Python will be demonstrated within this context. Reproducibility is a key problem in science, and complex data collection, alignment, reconstruction, and processing pipeline are particularly important. This project is funded by the DOE SBIR program, and is an active collaboration between developers at Kitware and scientists at Cornell University. | |||||||

14 July 2016, 11:00am at DL SCD Seminar, Hamish Carr (University of Leeds), "Topological Analysis and Visualisation" Over the past two decades, data generated either numerically or empirically has grown ever larger, while the human ability to process data has not. As a result, comprehension depends more and more on data analysis as a means of supporting (or supplanting) visualisation. One of the principal methods of exploiting analysis has been through the application of the mathematical discipline of topology, which studies invariant properties of functions. In practice, however, mathematics alone are not sufficient, and a significant effort has been required in computational algorithms for topological analysis, in building scalable software to implement them, in constructing user interfaces that take advantage of them, and in validating them by application to real world visualisation problems. In addition to this, however, these methods have also driven deeper understanding of the mathematical relationships between mathematical, computational and visual representations, and have thus uncovered hitherto unsuspected methods for visualising relationships between properties in numerical simulations. This talk will therefore concentrate on an overview of developments in the application of computational topology to visualisation and analysis tasks, but will also examine how the mathematics underlying these methods have also driven developments in non-topological visualisation

< < | 6 July 2016, 2:00pm-3:00pm SCD Seminar: Dave Pugmire (Oak Ridge National Laboratory), "Visualization and Analysis Services for Extreme Scale Supercomputers" The scientific data that are being generated today, and in the near future, will quickly outpace our ability to process and understand it. The data generated are growing in multiple ways, including the size of the data, the rate at which it arrives, and the varying types of data. Additionally, data are available from multiple sources, including for example, computational simulations and sensor data extracted from experiments. In such situations, workflows for the movement and management of data, as well as the analysis and visualization while the data are in transit, become even more critical, and increasingly challenging. At the same time, revolutionary changes are emerging in the architectures of supercomputers. These changes include tremendous increases in concurrency on each node, as well as a deep hierarchy of memory. These architectures are a challenge for currently running HPC codes, as well as visualization and analysis algorithms. We are, along with collaborators at other national laboratories, and universities, researching and developing a cohesive framework that will enable scientists to manage the growing data problem, and to enable them to extract knowledge and insight. Central to this work is a “Service Oriented Architectures” (SOA) framework that provides a clear separation from the data producers and consumers. Our framework is based on the ADIOS middleware layer, that manages the data as they are produced, and orchestrates movement through the deep memory hierarchy. The data consumers, in this case visualization and analysis services built from tools like VisIt, ParaView, VTK-m, and pbdR, will interact with the middleware layer for access to data, and for coordination to optimize access across the deep memory hierarchy. These services, which will be self-consistent, interoperable operations will enable scientists to construct multiple complex workflows. This talk will present the preliminary research on the development of this framework and the associated services as well as the initial results obtained working with several large-scale simulation codes running on the Titan supercomputer at ORNL. And finally, a detailed discussion on the future research plans and directions that will enable scientific insight on exascale computing systems. | |||||||

At the same time, revolutionary changes are emerging in the architectures of supercomputers. These changes include tremendous increases in concurrency on each node, as well as a deep hierarchy of memory. These architectures are a challenge for currently running HPC codes, as well as visualization and analysis algorithms. We are, along with collaborators at other national laboratories, and universities, researching and developing a cohesive framework that will enable scientists to manage the growing data problem, and to enable them to extract knowledge and insight. Central to this work is a “Service Oriented Architectures” (SOA) framework that provides a clear separation from the data producers and consumers. Our framework is based on the ADIOS middleware layer, that manages the data as they are produced, and orchestrates movement through the deep memory hierarchy. The data consumers, in this case visualization and analysis services built from tools like VisIt, ParaView, VTK-m, and pbdR, will interact with the middleware layer for access to data, and for coordination to optimize access across the deep memory hierarchy. These services, which will be self-consistent, interoperable operations will enable scientists to construct multiple complex workflows. This talk will present the preliminary research on the development of this framework and the associated services as well as the initial results obtained working with several large-scale simulation codes running on the Titan supercomputer at ORNL. And finally, a detailed discussion on the future research plans and directions that will enable scientific insight on exascale computing systems. | |||||||

< < | PROVISIONAL SEMINAR: 2:00pm-3:00pm Wednesday 13 January 2016 Jakob Sauer Jřrgensen Limited-data X-ray tomography and sparsity regularization Abstract: In this seminar I will give an overview of some recent results and ongoing projects within limited-data X-ray tomographic reconstruction and sparsity regularization. First, I will describe a special limited angle tomography problem in which metal bar sample holders cause cone-shaped parts missing in the sinogram. I will describe our attempts of characterizing and preliminary results of removing the resulting artifacts. Next, I will present a projection matching algorithm for automatically aligning tomographic projections of unknown exact orientation. In the present case we are interested in ultra-high resolution tomographic reconstruction from ptychography data. Currently, unknown sample translations and rotations at the nano-scale for example caused by vibration limit the achievable reconstruction quality. I will show preliminary results with simulated and real synchrotron ptychography data. Finally, I will mention our attempts of establishing a connection between image sparsity and the amount of undersampling admitted by sparsity-regularized reconstrution methods. In particular, I will describe simulation results suggesting how one may predict the sufficient number of projections to acquire based on the sparsity level of the scanned object. I will then point to a potential follow-up study for validation on real data using the SophiaBeads data set recently released from the University of Manchester | |||||||

< < | Abstract:Dynamic task-dependent parallelism is an increasingly popular programming model on shared-memory systems. Compared to data parallel loop-based concurrency, it promises enhanced scalability, load balancing and locality. These promises, however, are undermined by non-uniform memory access (NUMA). We show that it is possible to preserve the uniform hardware abstraction of contemporary task-parallel programming models, for both computing and memory resources, while achieving near-optimal data locality. Our run-time algorithms for NUMA-aware task and data placement are fully automatic, application-independent, performance-portable across NUMA machines, and adapt to dynamic changes. We take advantage of data-flow style task parallelism, where the privatization of task data enhances scalability through the elimination of false dependences, and enable fine-grained dynamic control over the placement of application data. | |||||||
Changed: | ||||||||
< < | In a second part, we present Aftermath, an interactive visualization tool for post-mortem trace analysis of cross-layer performance anomalies in dynamic task-parallel applications. We focus on the detection of anomalies inaccessible to state-of-the-art performance analysis techniques, including anomalies deriving from the interaction of multiple levels of software abstractions, anomalies associated with the hardware, and anomalies resulting from interferences between optimizations in the application and run-time system. Aftermath supports filtering, aggregation and joint visualization of key metrics and performance indicators, such as task duration, run-time state, hardware performance counters and data transfers. While not being specifically designed for NUMA architectures, Aftermath takes advantage of the explicit memory regions and dependence information in dependent task models to precisely capture long-distance and inter-core effects on complex, dynamic applications. | |||||||

< < | 2 September 2015 1:30pm-4:30pm Avizo training course: 2 workflows related to analysis of fibrous materials will be presented. The second use-case is based a PhD student of Philip Withers, Bo Yu, and illustrates advanced usage of Avizo modules for segmentation. Rémi Blanc "Fibre analysis with Avizo" Abstract: The presentation will highlight different usages of Avizo for tackling with fibrous materials. We consider two major use cases. First, in the case of high magnification with resolved fibers, we will present our recent XFiber extension for tracing the centerline of cylindrical fibers and extracting statistics about the length, orientation, or curvature. The second use case will consider woven composites imaged at lower magnification, where individual fibers cannot be distinguished but the oriented texture of the yarns is visible. We will detail an advanced workflow for classifying the yarns based on their orientation. (http://www.avizo3d.com![]() | |||||||
