A state estimator is an algorithm that computes the current state of a time-varying system from on-line measurements. Physical quantities such as measurements and parameters are characterised by uncertainty. Understanding how uncertainty affects the accuracy of state estimates is therefore a prerequisite to the application of such techniques to real(More)

It results in loss of elasticity of vessel walls, in focal development of plaques, and in irregular narrowing of the arterial lumen. The resultant impairment of blood flow may lead to heart attack, stroke, or gangrene of the limbs. The currently acceptable clinical method(More)
