A controlled experiment for corroborating the usefulness of class diagram metrics at the early phases of OO developments
The quality of class diagrams is critical because it has a great influence on the quality of the object oriented information system (OOIS) which are finally delivered. This fact mo...

Respiratory Signal Extraction for 4D CT Imaging of the Thorax from Cone-Beam CT Projections
Current methods of four-dimensional (4D) CT imaging of the thorax synchronise the acquisition with a respiratory signal to restrospectively sort acquired data. The quality of the 4...
