Proceedings of the Fourth Australasian Workshop on Health Informatics and Knowledge Management [Volume 120]

We are pleased to present the papers from the Australasian Health Informatics and Knowledge Management (HIKM) conference stream held on 20 January 2011 in Perth as a session of the Australasian Computer Science Week (ASCW) 2011. Formerly HIKM was named Health Data and Knowledge Management, however the inclusion of the health informatics term is timely given the current health reform. The submissions to HIKM 2011 demonstrated that Australasian researchers lead with many research and development innovations coming to fruition. Some of these innovations can be seen here, and we believe further recognition will accomplish by continuation to HIKM in the future. The HIKM conference is a review of health informatics related research, development and education opportunities. The conference papers were written to communicate with other researchers and share research findings, capturing each and every aspect of the health informatics field. They are namely: conceptual models and architectures, privacy and quality of health data, health workflow management patient journey analysis, health information retrieval, analysis and visualisation, data integration/linking, systems for integrated or coordinated care, electronic health records (EHRs) and personally controlled electronic health records (PCEHRs), health data ontologies, and standardisation in health data and clinical applications.

Measurement of shock stand-off distance on a 120 degrees blunt cone model at hypersonic Mach number in Argon

The flow around a 120 degrees blunt cone model with a base radius of 60mm has been visualised at Mach 14.8 and 9.1 using argon as the test gas, at the newly established high speed schlieren facility in the IISc hypersonic shock tunnel HST2. The experimental shock stand off distance around the blunt cone is compared with that obtained using a commercial CFD package. The computed values of shock stand off distance of the blunt cone is found to agree reasonably well with the experimental data.

Diário da Constituinte [gravação de vídeo] : [programa n. 120]

Representantes da Associação dos Delegados de Polícia (ADEPOL), reuniram-se com o Deputado João Natal (PMDB-GO) e apresentaram sugestões para a melhoria das condições de trabalho da classe. Na sessão O Povo Pergunta, cidadã indaga se a divisão dos Estados acarretará maior disponibilidade de verbas. Nabor Júnior (PMDB-AC) responde que é favorável, dentro das possibilidades econômicas do país, a redivisão territorial dos Estados e que o argumento de falta de recursos da União para custear a implantação desses novos Estados não tem consistência. Os deputados da Assembleia Legislativa da Bahia entregaram a Marcelo Cordeiro (PMDB-BA), 1º Secretário da Assembleia Nacional Constituinte (ANC), documento pedindo a preservação da unidade do território baiano. Coriolano Salles, Presidente da Assembleia, relata que o povo baiano deseja que a Bahia se mantenha íntegra, indivisível. Jorge Hage (PMDB-BA) afirma que não há razão para enfraquecer um Estado com as dimensões, perspectivas e potencial como o da Bahia e acredita que a Assembleia Nacional Constituinte não aprovará a divisão. Na questão da reforma tributária, os municipalistas começaram a agir junto a Comissão de Sistematização, no sentido de garantir os direitos dos municípios. Os Deputados Vivaldo Barbosa (PDT-RJ), Hélio Manhães (PMDB-ES) e Maguito Vilela (PMDB-GO), da bancada municipalista apoiam a descentralização da receita nacional.

Compact 120 TW Ti: sapphire laser system with a high gain final amplifier

A 120TW/36fs laser system based on Ti:sapphire chirped-pulse amplification (CPA) has been successfully established in our lab. The final four pass Ti:sapphire amplifier pumped by an energetic single-shot Nd:YAG-Nd:glass laser was designed and optimized. With 24J/8ns pump energy at 532 nm, 300 mJ/220 ps chirped pulse was amplified to 5.98 J in this amplifier, and a total saturated gain of similar to 20 was achieved. The focused intensity of compressed beam could reach to 10(20) W/cm(2) with the M-2 of similar to 2.0. (c) 2005 Elsevier Ltd. All rights reserved.

Comment on "Acoustic chaos in a duct with two separate sound sources" [J. Acoust. Soc. Am. 110, 120-126 (2001)] (L)

In a paper published in this journal in 2001 by Dong [W. G. Dong, X. Y. Huang, and Q. L. Wo, J. Acoust. Soc. Am. 110, 120-126 (2001)] it was claimed that acoustic chaos was obtained experimentally by the nonlinear interaction of two acoustic waves in a duct. In this comment a simple experimental setup and an analytical model is used to show that the dynamics of such systems corresponds to a quasiperiodic motion, and not to a chaotic one. © 2008 Acoustical Society of America.
