A Survey of Inverse Surface Design From Light Transport Behavior Specification

Inverse surface design problems from light transport behavior specification usually represent extremely complex and costly processes, but their importance is well known. In particular, they are very interesting for lighting and luminaire design, in which it is usually difficult to test design decisions on a physical model in order to avoid costly mistakes. In this survey, we present the main ideas behind these kinds of problems, characterize them, and summarize existing work in the area, revealing problems that remain open and possible areas of further research.     

On-demand Virtual Neonatal Intensive Care units supporting rural, remote and urban healthcare with Bush Babies Broadband

Premature and ill term babies born in regional Australia must be moved to another hospital with Neonatal Intensive Care Unit (NICU) facilities. Transferred pre-term and critically ill term babies have higher mortality rates and much higher rates of long term disability than similar babies born in hospitals with NICU facilities. This paper details the Bush Babies Broadband project that aims to significantly improve the quality of treatment for babies born in rural, remote as well as urban areas by providing the first on-demand virtual NICU architecture in Australia. Real-time data collected from medical monitors and ventilators attached to the baby, audiovisual streams and static physiological data such as X-ray images are transmitted to the consulting Neonatologist to gain a better picture of the patient's condition than is currently available. The key contribution of this significant research is the infrastructure providing a mechanism for Neonatologists to receive information directly from a regional hospital, thereby preventing, in some cases, the immediate need to move the baby. A key benefit of this framework is that it is available to link regional hospitals with the supporting NICU Neonatologist ‘on demand’ eliminating the need to establish permanent point to point connections. This paper further describes the application of that architecture to a specific pilot connecting the Bathurst regional hospital with Neonatologists within the NICU at Nepean Hospital, Penrith Australia.

Complete corrosion inhibition of lamellar zinc pigment in aqueous alkaline media

Lamellar zinc pigment reacts in aqueous alkaline media (e.g., water-borne paints) with the evolution of hydrogen. This corrosion reaction can be inhibited by 2-nitrophenol (2-NP), 2,4-dinitrophenol (2,4-DNP), 2-hydroxy-3,5-dinitro-benzoic acid (HDNBA) and 2-hydroxy-3-nitro-benzoic acid (2-H-3-NBA) which all have a nitro-group ortho to a hydroxy-group; this structural part of the inhibitors can be considered as a potential chelating group which may explain the corrosion inhibiting effect. As a rule, with triethylamine (TEA) as neutralizing agent corrosion inhibition is slightly better when compared to dimethylethanolamine (DMEA). With TEA there is complete corrosion inhibition with addition of 2,4-DNP at pH 8 and 10; with 2-H-3-NBA there is complete inhibition at pH 10.
