Geographical variation in coronary revascularisation rates Sir-I found the paper by Black et all on the geographical variation in coronary re-vascularisation rates extremely interesting. This is a vital area if the NHS is to try to achieve a more equitable service. I am impressed by the tremendous size of the study embarked upon to investigate these variations and the wealth of information avai...

The design of experiment (DoE) approach developed for experiments requiring cost and time is applied in many disciplines. Unfortunately, the insufficient use DoE technique physics led to emergence this study. This study aims demonstrate applicability field with a case most widely used full factorial experimental was damped driven pendulum Length (m), dumpling (Newton), mass (kg) as independent ...

We present a new method for recording digital holograms under incoherent illumination. Light is reflected from a 3D object, propagates through a diffractive optical element (DOE), and is recorded by a digital camera. Three holograms are recorded sequentially, each for a different phase factor of the DOE. The three holograms are superposed in the computer, such that the result is a complex-value...
