These models sum multiple time series such as barometric pressure, tidal potential, and background water levels to simulate non-pumping water levels. The amplitude and phase of each time series are adjusted so that synthetic water levels match measured water levels during periods unaffected by an aquifer test. Differences between synthetic and measured water levels are minimized with a sum-of-squares objective function. Jon,

As far as I know these include the only published closed form solutions for finding the neutral axis of beams of complex (i.e. non-rectangular) cross section. Also included are UDFs for solving quartic, cubic and quadratic equations, and routines for plotting shapes from coordinates: http://www.interactiveds.com.au/software/Beam%20Design%20Functions.zip See: http://newtonexcelbach.wordpress.com/ for more Jon – here are my three entries:

At http://www.excelcalcs.com our solved problems cover many subjects including Strength, Beams, Buckling, Civil Engineering, Cracks, Finite Element, Frames, Materials, Plates, Stress Concentration, Structural Details, Torsion, Pressure Vessels, Machine Design, Bolts and Threads, Gears, Pins and Joints, Ropes and Cables, Shafts, Welds, Math, Geometry, Heat Transfer (Conduction, Convection, Radiation & Combined), Dynamics, Fluids Mechanics, Piping, Electricity and Finance. Many of the calculations require the XLC addin to be installed - this displays Excel Cell formulae as Mathematical notation. It is very useful if you need to present the calculation method like in a set of engineering calculations. It is also a very useful teaching tool. Our users say it gives MathCad functionality to Excel and its all free. Jon we have a monthly newsletter so I’ll let all our users know about your competition in the next edition.
