Identifying information needs of patients with IgA Nephropathy, using an innovative social media stepped analytical approach (2021)
Journal Article

Introduction
Increasingly people with kidney disease are using social media to search for medical information and to find peer-support. IgA nephropathy (IgAN) predominantly affects young adults, demographically the biggest users of...

Towards the extraction of statistical information from digitised numerical tables - the Medical Officer of Health reports scoping study (2019)
Presentation / Conference Contribution

Numerical data of considerable significance is present in historical documents in tabular form. Due to the challenges involved in the extraction of this data from the scanned documents it is not available to researchers in a useful representation tha...

Highlights of the novel dewaterability estimation test (DET) device (2019)
Journal Article
Scholz, M., Almuktar, S., Clausner, C., & Antonacopoulos, A. (2020). Highlights of the novel dewaterability estimation test (DET) device. Environmental Technology, 41(20), 2594-2602. https://doi.org/10.1080/09593330.2019.1575916

Many industries, which are producing sludge in large quantities, depend on sludge dewatering technology to reduce the corresponding water content. A key design parameter for dewatering equipment is the capillary suction time (CST) test, which has, ho... Read More about Highlights of the novel dewaterability estimation test (DET) device.

Creating a complete workflow for digitising historical census documents : considerations and evaluation (2017)
Presentation / Conference Contribution

The 1961 Census of England and Wales was the first UK census to make use of computers. However, only bound volumes and microfilm copies of printouts remain, locking a wealth of information in a form that is practically unusable for research. In this...

Unearthing the recent past : digitising and understanding statistical information from census tables (2017)
Presentation / Conference Contribution

Censuses comprise a wealth of information at a large (national) scale that allow governments (who commission them) and the public to have a detailed snapshot of how people live (geographical distribution and characteristics). In addition to underpinn... Read More about Unearthing the recent past : digitising and understanding statistical information from census tables.

Effective geometric restoration of distorted historical documents for large-scale digitization (2017)
Journal Article
Yang, P., Antonacopoulos, A., Clausner, C., Pletschacher, S., & Qi, J. (2017). Effective geometric restoration of distorted historical documents for large-scale digitization. IET Image Processing, 11(10), 841-853. https://doi.org/10.1049/iet-ipr.2016.0973

Due to storage conditions and material’s non-planar shape, geometric distortion of the 2-D content is widely present in scanned document images. Effective geometric restoration of these distorted document images considerably increases character recog...
