The applicability of Brillouin scattering to flow field diagnostics

To fill the void between turbulence theory and experiment; particularly in the flow fields consisting of monatomic gases, for example in wind tunnels, means of measuring fluctuating quantities are needed. In the area of density fluctuation measurement, the optical method of Brillouin scattering was suggested. This was based on the theory, that the Brillouin scattered intensity is proportional to a function of density. In this investigation the potential of this method as a diagnostic tool was studied. Here the density fluctuations in gases were sought. Continuous wave lasers and interferometers were used as the primary illuminating source and scattered light filters respectively

Quantitative Ultrasonic Tomographic Imaging

An ultrasonic transmission technique is described which images the velocity variation within metal parts. The arrival time of the first ultrasonic pulse to traverse the object is detected and displayed as a gray scale on a cathode ray tube while the part is being scanned horizontally and vertically. The velocity variation imaged within several cast turbine parts will be shown. The system can detect voids as small as 0.020 inch. With a more complex computer program and knowing the dimensions of the part, tomographic reconstruction of the velocity variation within parts with curved surfaces should be possible

MEDICAL RECORD SUPPORT FOR EFFECTIVE DISCHARGE PLANNING

Little is known about the Information Technology artefacts which help inform decision-making to sup-port people returning home following a hospital stay. Content, delivery, timing and information about personal circumstances form integral components of person-centred discharge planning. From an Information Systems (IS) perspective, understanding barriers to information flow, artefacts in use and the context in which they are presented to health care professionals is the first step to explore how currently used IS support or fail to support the discharge process. This research-in-progress uses Roy’s Adaption Model and Adaptive Structuration Theory to explore to what extent patient infor-mation documented in the medical record supports and enables person-centred discharge planning. We aim specifically to understand how the medical record shapes discharge planning through clini-cian-to-clinician and clinician-to-patient information sharing to support a patient’s recovery journey when home. Findings suggest that the medical record is insufficient to support and enable person-centred discharge planning. We suggest how these limitations can be overcome to improve person-centred discharge planning to assist and facilitate patients’ transition home
