Model And Software Development
This consultant's expertise in polymer and composite materials modeling and simulation was developed through more than two decades of both hands-on work and technical leadership (in an industrial environment) in the development, implementation, and application of a broad range of modeling and simulation techniques and software. Here are two examples of how this expertise has benefited clients :
The development of advanced polymeric optical fibers (POFs) is a technology area that offers great opportunities while presenting significant obstacles to success. A key problem is the selection and/or custom design, for use in manufacturing POFs, of polymer molecular structures that will result in the lowest possible signal loss signal during transmission. This expert consultant was asked by a Fortune 500 company to help it in evaluating candidate molecular structures for POF applications. This consultant concluded that the most cost-effective help that could be provided was to develop a quantitative structure-property relationship (QSPR) model and its software implementation for calculating intrinsic signal losses in POFs as a function of the molecular structure of the polymer and the wavelength (and frequency) of the signal. When the client agreed with this strategy, a model was put together that calculates the intrinsic optical loss as a function of the molecular structure of the polymer, directed a software engineer in implementing this model into software (an Excel macro) that performs the calculations and provides the results in both tabular and graphical format, and provided the software to the client for use by its R&D personnel.
Standards developed by the American Society of Mechanical Engineers (ASME) are used in many repair situations to determine how to design a repair system that will be effective in restoring functionality, safe, and durable. These standards typically combine equations from the engineering sciences covering various possible situations (such as type and extent of damage, and geometry of damaged component) with considerations based on the properties of materials that can potentially be used in making a repair, in a very complex manner. It is often left to the user to interpret these standards and determine how to use the recommended procedures correctly. A client requested help with interpreting one of these standards and putting together a software program that the field technicians of its customers can use in practical applications. This consultant studied the appropriate standard very carefully, and also contacted the chairman of the committee that had prepared the standard to request clarification of its subtleties. This consultant determined the combination of approaches and equations taught by the standard that were most relevant to the use of the client's products in the field. Then a clear and concise document was written providing information and instructions covering these aspects of the standard, and a software engineer was directed in implementing the resulting model into software (an Excel macro) that performs the calculations and provides the results in tabular format. Upon the client's request, this consultant is now participating in the ongoing quarterly meetings of the committee that set up the standard as it works on further refinements of it.
