CLM/Systems, Tampa, FL

Applied Mathematician, 1990-1998

Designed and coded CEAL (Civil Engineering Automation Library) command modules in F90 and C under DEC VAX/VMS and MS-DOS. Performed procedural and mathematical analysis of 3-dimensional, superelevated bridge deck geometry for steel detailing. Provided consulting on multilayered quantities computation for tunneled, bridged, and ramped interstate highway reconstruction. Conducted research into spiral splines, boolean combinations of polygons, 3D coordinate transforms, and conformal map projections. Designed and coded VB applications for digital terrain modeling using Intergraph GeoMedia API under Win 95/98/NT.

Algorithms included orthogonal least squares line, circle, parabola, and spiral curve fitting; constrained least squares parabolic curve fitting; constrained vertical curve constructions; finite element volumes; tapered offset profile constructions; compound spiral curve intersection, projection, tangent, offset, and tapered offset constructions; circular, parabolic, and spiral curve graphics rendering optimization; and Helmert coordinate transformations.
