Audit and Change Analysis of Spreadsheets (2008)
Nash, John C., Smith, Neil, Adler, Andy
Because spreadsheets have a large and growing importance in real-world work, their contents need to be controlled and validated. Generally spreadsheets have been difficult to verify, since data and...
GREIT: towards a consensus EIT algorithm for lung images, (2008)
Adler, Andy, Arnold, John, Bayford, Richard, Borsic, Andrea, Brown, Brian, Dixon, Paul, ...
Recently, electrical impedance tomogra- phy (EIT) has begun to see a signi¯cant clinical in- terest for monitoring of ventilated patients. The key capability of EIT is to provide real-time images of...
Evaluating Deformation Corrections in Electrical Impedance Tomography (2008)
Boyle, Alistair, Lionheart, William R.B., Gomez-Laberge, Camille, Adler, Andy
Electrical Impedance Tomography (EIT) uses the difference in measurements between surface electrodes to reconstruct an image of the conductivity of the contained medium. However, changes in...
Simple FEMs aren’t as good as we thought: experiences developing EIDORS v3.3 (2008)
Adler, Andy, Borsic, Andrea, Polydorides, Nick, Lionheart, William R.B.
In this paper, we 1: announce EIDORS version 3.3, and clarify the new features and changes to the software. Brie y, the new version includes: a) interfaces to FEM generation (distmesh, netgen) and...
A measure of the information content of EIT data (2008)
Adler, Andy, Youmaran, Richard, Lionheart, William R.B.
We ask: how many bits of information (in the Shannon sense) do we get from a set of EIT measurements? Here, the term information in measurements (IM) is denotned as: the decrease in uncertainty about...
TellTable Spreadsheet Audit: from Technical Possibility to Operating Prototype (2008)
Nash, John, Adler, Andy, Smith, Neil
At the 2003 EuSpRIG meeting, we presented a framework and software infrastructure to generate and analyse an audit trail for a spreadsheet file. This report describes the results of a pilot...
Total Variation Regularization in Electrical Impedance Tomography (2007)
Borsic, Andrea, Graham, Brad M., Adler, Andy, Lionheart, William R.B.
This paper presents an evaluation of the use of Primal Dual Methods for efficiently regularizing the electric impedance tomography (EIT) problem with the Total Variation (TV) functional. The Total...
Uses and abuses of EIDORS: An extensible software base for EIT (2006)
Adler, Andy, Lionheart, William R.B.
EIDORS is an open source software suite for image reconstruction in electrical impedance tomography and diffuse optical tomography, designed to facilitate collaboration, testing and new research in...
Sparse Matrix Implementation in Octave (2006)
There are many classes of mathematical problems which give rise to matrices, where a large number of the elements are zero. In this case it makes sense to have a special matrix type to handle this...
Knowing what was done: uses of a spreadsheet log file (2005)
Spreadsheet use in educational environments has become widespread, likely because of the flexibility and ease of use of these tools. However, they have serious shortcomings if the teacher is to...

The following *oct files will read jpg,bmp,p?m.
Cieslewicz, Grzegorz, Tomkinson, Adrian, Adler, Andy, Duez, Catherine, Schwarze, Jurgen, Takeda, Katsuyuki, ...
Early-phase reactions (EPRs) and late-phase reactions (LPRs) are characteristic features of bronchial asthma, although the pathogenetic mechanisms responsible for each of the responses are not fully...
Adler, Andy, Morse, Stephen I.
The activity of soluble lymphocytosis-promoting factor (LPF) from Bordetella pertussis decreased after brief in vitro incubation with lymphoid cells or erythrocytes. The LPF activity was found to be...

Taub, Robert N., Rosett, Walter, Adler, Andy, Morse, Stephen I.
The mechanism by which Bordetella pertussis organisms and their products induce lymphocytosis in mice was analyzed in terms of the localization of syngeneic Cr-51-labeled lymph node cells. Labeled...
