  • A method out of the madness: OhioLINK's collaborative response to the serials crisis
    Serials: The Journal for the Serials Community, 2001
    Co-Authors: Thomas J. Sanville
    Abstract:

    Electronic Desktop delivery allows far greater information use than was previously possible. Based on the OhioLINK Electronic Journal Center (EJC) experience, improved ease of access has demonstrated the high elasticity in information usage. Demand on EJC services provides proof of the dramatic benefits from expanded access. Patrons have executed over 1.8 million article downloads. On average each Ohio university uses 4 times more titles than they previously held in print, and 52% of downloaded articles were not available in print on each campus. Small and two-year colleges are also beneficiaries through first-time access to scholarly journals. Libraries and consortia should promote expanded journal access by taking advantage of a sustainable purchasing model that maximizes information use.

  • A Method Out of the Madness: OhioLINK's Collaborative Response to the Serials Crisis Three Years Later A Progress Report
    The Serials Librarian, 2001
    Co-Authors: Thomas J. Sanville
    Abstract:

    The current practices of journal acquisition are grounded in the legacy of a print-bound world in which each library is an island of access for its own patrons. With Electronic Desktop delivery to information, increased ease of access allows far greater information use than previously possible. The extent of this additional use is still an open question, but based upon the OhioLINK experience thus far, it appears that improved ease of access has demonstrated the high elasticity in information usage. Libraries and consortia must seek to enable this desirable outcome by adopting purchase models that provide for expanded journal access. The first twenty-six months of operation of the OhioLINK Electronic Journal Center (EJC) is an exemplary illustration of the dramatic benefits of expanded access. Patrons have executed over 1.2 million article downloads. On average each Ohio university uses 3.5 times more titles than they previously held in print, and 51% of downloaded articles were not available in print on each campus. Small and two-year colleges are also beneficiaries through first-time access to scholarly journals. As the evolution to broad scale Electronic access continues, libraries and consortia must take advantage of the opportunities illustrated by the EJC that fashion a sustainable economic model of information purchase that maximizes information use.

  • A method out of the madness: OhioLINK's collaborative response to the serials crisis four years later: Progress report
    2001
    Co-Authors: Thomas J. Sanville
    Abstract:

    Electronic Desktop delivery allows far greater information use than was previously possible. Based on the OhioLINK Electronic Journal Center (EJC) experience, improved ease of access has demonstrated the high elasticity in information usage (The OhioLINK experience support the adoption of new practices based on consortium-level licensing). Demand on EJC services provides proof of the dramatic benefits from expanded access. Patrons have executed over 1.8 million article downloads. On average each Ohio university uses 4 times more titles than they previously held in print, and 52% of downloaded articles were not available in print on each campus. Small and two-year colleges are also beneficiaries through first-time access to scholarly journals. Libraries and consortia should promote expanded journal access by taking advantage of a sustainable purchasing model that maximizes information use.

  • Use levels and new models for consortial purchasing of Electronic journals
    Library Consortium Management: An International Journal, 1999
    Co-Authors: Thomas J. Sanville
    Abstract:

    The current practices of journal acquisition are grounded in the legacy of a print‐bound world in which each library is an island of access for its own patrons. But with Electronic Desktop delivery of information, the increased ease of access allows far greater information use than previously possible. The extent of this additional use is still an open question, but based on the OhioLINK experience thus far, it appears that improved ease of access has demonstrated the high elasticity in information usage. Libraries and consortia must seek to enable this desirable outcome by adopting purchase models that provide for expanded journal access. The first 18 months of operation of the OhioLINK Electronic Journal Center (EJC) is an exemplary illustration of the dramatic benefits of expanded access. Patrons have executed over 535,000 article downloads. On average each Ohio university uses three times more titles than they previously held in print, and over 50 per cent of downloaded articles were not available in print on each campus. Small and two‐year colleges are also beneficiaries through first‐time access to scholarly journals. As the evolution to broad scale Electronic access continues, libraries and consortia must take advantage of the opportunities illustrated by the EJC that fashion a sustainable economic model of information purchase that maximizes information use.

  • SOOT MASS ESTIMATION FROM ELECTRICAL CAPACITANCE TOMOGRAPHY IMAGING FOR A DIESEL PARTICULATE FILTER
    Volume 4: Dynamics Vibration and Control, 2019
    Co-Authors: Salah Eldin Karar Hassan, Sohel Anwar
    Abstract:

    The Electrical capacitance tomography (ECT) method has recently been adapted to obtain tomographic images of the cross section of a diesel particulate filter (DPF). However, a soot mass estimation algorithm is still needed to translate the ECT image pixel data to obtain soot load in the DPF. In this research, we propose an estimation method to quantify the soot load in a DPF through an inverse algorithm that uses the ECT images commonly generated by a back-projection algorithm. The grayscale pixel data generated from ECT is used in a matrix equation to estimate the permittivity distribution of the cross section of the DPF. Since these permittivity data has direct correlation with the soot mass present inside the DPF, a permittivity to soot mass distribution relationship is established first. A numerical estimation algorithm is then developed to compute the soot mass accounting for the mass distribution across the cross-section of the DPF as well as the dimension of the DPF along the exhaust flow direction. Firstly, ANSYS Electronic Desktop software is used to compute the capacitance matrix for different amounts of soot filled in the DPF, furthermore it also analyzed different soot distribution types applied to the DPF. The Analysis helped in constructing the sensitivity matrix which was used in the numerical estimation algorithm. Experimental data have been further used to verify the proposed soot estimation algorithm which compares the estimated values with the actual measured soot mass to validate the performance of the proposed algorithm.
