Applied Mathematics, Computation, and Simulations
Further extensions of UCAN-II,
a block oriented digital simulation language that serves as a dynamic differential equations
solvers are planned. It is implemented on mainframes and mini's and now a PC version
micro-UCAN is operational. Offline graphics, self-generating computional logic flow diagrams,
along with special research and educational applications, are in early stages of development.
Work on the mathematics for modeling and simulation of non-isothermal gas absorption in a
packed column has been undertaken. This work requires additional mathematical refinement and
evaluation by comparing the model to real processes utilizing earlier published data.
Hazardous Waste Process Studies
Pervaporation membrane mass transfer studies: In
work already completed, it was demonstrated that the pervaporization process can be used to
reduce traces of contaminating chlorinated inorganics in drinking water by as much as 500-fold.
Work is continuing in this area to develop better membranes. A number of additional projects
involve: Improving the experimental testing of membranes, producing more highly selective
membranes, and developing pervaporization applications which lead to new separation processes
utilizing kinetics and thermodynamics along with process dynamics.
Life Sciences - Biotechnology
Development and testing of membranes which adapt the techniques of affinity chromatography
to the purification of gene-altered microbe products is in early planning stages.
Studies concerning laser applications include a series of ongoing projects: the rapid detection and
identification of microorganisms in the environment by induced fluoresence; sterilization of
biological fluids by coherent light as a replacement for chemical additives; and interaction of
coherent light with tissue for the determination of abnormalities.
