Object-based three-dimensional X-ray imaging
A form of three-dimensional X-ray imaging, called Object 3-D, is introduced, where the relevant subject material is represented as discrete ‘objects’. The surface of each such object is derived accurately from...

Modelling Respiratory Sinus Arrhythmia and its Application to the Study of Neuropathy
Evidence for respiratory waves in blood pressure was first presented by Ludwig in 1847. More recently these fluctuations have become known as Mayer waves (Penaz, 1978); the wave of respiratory origin is now ca...
