Software reliability perspectives [PDF]
Software which is used in life critical functions must be known to be highly reliable before installation. This requires a strong testing program to estimate the reliability, since neither formal methods, software engineering nor fault tolerant methods ...

Reliability, life prediction and proof testing of ceramics
, 1974 Abstract : A critical review is presented of the use of proof testing as a design method for assuring the reliability of structural components. The advantage of proof testing over the statistical approach used for design lies in the insensitivity of the proof testing method to the detailed history of handling or processing of structural components ...

Measuring quality of life for an economic evaluation of aphasia: First steps [PDF]
, 2013 Health economists typically use the Quality Adjusted Life Year (QALY) when conducting economic evaluations of healthcare investments. We have begun investigating methods to obtain QALYs for aphasia by developing a pictographic version of the Time Trade ...
