Gaining Physician Buy-In for Disease Management Initiatives
Disease Management and Health Outcomes, 1999Co-Authors: Harry L. LeiderAbstract:Achieving the support of physicians is perhaps the most difficult challenge to successfully implementing a disease management programme. Most physicians are sceptical of disease management initiatives. Many perceive these programmes to be a threat to their professional autonomy or an Unreasonable Demand on their limited time with patients. Nonetheless, failure to achieve high levels of physician support results in suboptimal levels of patient identification, enrolment and effectiveness of interventions. Therefore, it is impossible to achieve good outcomes across a large population without achieving physician buy-in. Leaders of organisations implementing disease management programmes can use 5 core strategies to achieve physician buy-in for disease management programmes. These are: education, enlisting champions, ‘creating a box’, building on success, and sharing the gains. Providing education corrects misconceptions many physicians have about disease management. Champions are respected clinicians who are willing to share their positive views of a disease management programme. ‘Creating a box’ sets clear goals and expectations for physicians who consider building a disease management programme. Building on success involves demonstrating that a relatively easy programme works before attempting a more complex or controversial programme. Finally, sharing the gains means that physicians should be rewarded for their time and effort supporting disease management programmes.

Interactions in a multiple voice coil digital loudspeaker
Journal of The Audio Engineering Society, 2000Co-Authors: Yaxiong Huang, Simon Busbridge, Peter A. FryerAbstract:A 7-bit digital multiple-voice-coil loudspeaker and a constant current driver have been constructed and evaluated. Two's complement coding offers the best compromise between complexity, excessive power consumption, and distortion due to baseline drift. The effect of motion impedance and mutual coupling in a multiple-coil system is found to magnify the effective impedance of an individual coil by its weighting in the binary representation. This effect places an Unreasonable Demand on the output impedance of the driver unless damping is controlled, which can be achieved most effectively by a short-circuited voice coil. Optimum damping occurs when the damping resistance is equal to the negative resistance of an individual coil.

Interactions in a multiple voice coil loudspeaker
1999Co-Authors: Yaxiong Huang, Simon Busbridge, Peter A. FryerAbstract:A seven-bit digital multiple voice coil loudspeaker and constant current driver has been constructed and evaluated. Two's compliment coding offers the best compromise between complexity, excessive power consumption and distortion due to base-line drift. The effect of motion impedance and mutual coupling in a multiple coil system is found to magnify the effective impedance of an individual coil by its weighting in the binary representation. This effect places an Unreasonable Demand on the output impedance of the driver unless damping is controlled, which can most effectively be achieved by a shorted voice coil. Optimum damping occurs when the damping resistance is equal to minus the resistance of an individual coil

Visualisation of plant disturbances using self-organising maps
Computers & Chemical Engineering, 1996Co-Authors: Jannie S.j. Van Deventer, D.w. Moolman, Chris AldrichAbstract:Ill-defined processes such as the froth flotation of minerals are mostly controlled in an empirical way by using rules of thumb. These processes involve so many variables that the plant operator finds it difficult to visualise or even observe a change in process conditions. In froth flotation the operator is supposed to visually observe process changes from the appearance of the froth, which is an Unreasonable Demand under industrial conditions. An on-line computer vision system based on a textural analysis of the froth phase has been developed in South Africa and has been in operation on two industrial plants since early 1995. Textural parameters are determined on-line, and disturbances in process conditions, such as a change in reagent addition or froth depth, are visualised via a Self-Organizing Map (SOM) neural net.

ICNN - The tracking of changes in chemical processes using computer vision and self-organizing maps
Proceedings of ICNN'95 - International Conference on Neural Networks, 1Co-Authors: Jannie S.j. Van Deventer, Chris Aldrich, D.w. MoolmanAbstract:Frequently, chemical processes involve so many independent and dependent variables that the plant operator finds it difficult to visualise or even observe a change in process conditions. In froth flotation the operator is supposed to visually observe process changes from the appearance of the froth, which is an Unreasonable Demand under industrial conditions. An online computer vision system based on a textural analysis of the froth phase has been developed in South Africa and has been in operation on an industrial flotation plant since the end of 1994. This system determines textural parameters online, and tracks the changes in process conditions via a self-organizing map (SOM) incorporating a Kohonen layer. This monitoring system warns the operator about fluctuations in reagent addition, and gives an idea of the type of froth encountered. In a further example, changes in the mineralogical characteristics of gold ores are represented on an SOM map, based on the diagnostic leaching behaviour of such ores.
