    <i>In situ</i> observation of strain and phase transformation in plastically deformed 301 austenitic stainless steel

    To inform the design of superior transformation-induced plasticity (TRIP) steels, it is important to understand what happens at the microstructural length scales. In this study, strain-induced martensitic transformation is studied by in situ digital image correlation (DIC) in a scanning electron microscope. Digital image correlation at submicron length scales enables mapping of transformation strains with high confidence. These are correlated with electron backscatter diffraction (EBSD) prior to and post deformation process to get a comprehensive understanding of the strain-induced transformation mechanism. The results are compared with mathematical models for enhanced prediction of strain-induced martensitic phase transformation

    The bb-adic tent transformation for quasi-Monte Carlo integration using digital nets

    Full text link
    In this paper we investigate quasi-Monte Carlo (QMC) integration using digital nets over Zb\mathbb{Z}_b in reproducing kernel Hilbert spaces. The tent transformation, or the baker's transformation, was originally used for lattice rules by Hickernell (2002) to achieve higher order convergence of the integration error for smooth non-periodic integrands, and later, has been successfully applied to digital nets over Z2\mathbb{Z}_2 by Cristea et al. (2007) and Goda (2014). The aim of this paper is to generalize the latter two results to digital nets over Zb\mathbb{Z}_b for an arbitrary prime bb. For this purpose, we introduce the {\em bb-adic tent transformation} for an arbitrary positive integer bb greater than 1, which is a generalization of the original (dyadic) tent transformation. Further, again for an arbitrary positive integer bb greater than 1, we analyze the mean square worst-case error of QMC rules using digital nets over Zb\mathbb{Z}_b which are randomly digitally shifted and then folded using the bb-adic tent transformation in reproducing kernel Hilbert spaces. Using this result, for a prime bb, we prove the existence of good higher order polynomial lattice rules over Zb\mathbb{Z}_b among the smaller number of candidates as compared to the result by Dick and Pillichshammer (2007), which achieve almost the optimal convergence rate of the mean square worst-case error in unanchored Sobolev spaces of smoothness of arbitrary high order

    The Dynamics of Transformation in the Development of Digital Services

    Service providers are increasingly depending and using digital infrastructure and tools provided by digital platforms to transform their services and develop digital ones that meet the needs of heterogeneous end users. However, while there is an emerging literature of developing digital services, little is known about the dynamics of transformation. Using multiple cases of firms that develop digital services, the digital service taxonomy was synthesized to understand the dynamics of transformation in developing digital services. This study identifies five main dynamics: the services experience, the service process, the service capabilities, the service environment and the service delivery.  Each of those dynamics and their associated factors is explored under the objectives of business, interaction and technology. This enables us to extend the existing literature on digital service development in particular and contributes to the research of digital innovation in general

    Understanding Cognition Across Modalities for the Assessment of Digital Resources

    Get PDF
    Drawing from the theories of the cognitive process, this paper explores the transmission, retention and transformation of information across oral, written, and digital modes of communication and how these concepts can be used to examine the assessment of digital resource tools. The exploration of interactions across modes of communication is used to gain an understanding of the interaction between the student, digital resource and teacher. Cognitive theory is considered as a basis for the assessment of digital resource tools. Lastly, principles for the assessment of digital resource tools are presented along with how assessment can be incorporated in the educational practice to enhance learning in higher education

    DevOps is Bigger than IT: Driving Digital Transformation in Libraries

    Get PDF
    The DevOps movement represents a paradigm shift in software development, but there are misconceptions about what it really means. It’s much more nuanced than simply adding a DevOps engineer to your team or asking systems administrators and developers to play well together. At its core, DevOps is about culture change. In this talk, we will define the CALMS framework of DevOps and the people, technical, and organizational factors that challenge its adoption. We will share specific examples of how DevOps is changing the way we work on digital library projects at Ohio State University Libraries and how its universal principles can drive large-scale digital transformation in libraries.

    Business School Techspectations is the second in a series of reports based on research by the DCU Leadership, Innovation and Knowledge Research Centre (LInK) at DCU Business School. With its roots in an Irish business school, it is no surprise that LInK’s mission is to strengthen the competitiveness, productivity, innovation and entrepreneurial capacity of the Irish economy. Ireland’s next generation transformation will be enabled by information and communication technologies (ICT) and digital participation by members of Irish society. As a university research centre we have an important role to play in supporting education, industry and government to accelerate this transformation
