How to model the dynamic impact of transport on boxes containing vials?

Let's consider that we have large number of boxes being transported in a truck. These boxes contain certain number of vials which in turn contain some other products. Now one would like to simulate the impact of truck vibration during the transport…

Shallow water model for year-round watershed runoff

I have an (maybe not so clever) idea to apply the shallow water model for computing the year-round watershed runoff of a catchment. It means using of real topography with variable slopes and roughness, length of the real time period about 31536000…

A direct numerical method for determining a relaxation function from a known creep function

Both the creep function and the relaxation function are connected by the convolution integral. The usual method for calculating the relaxation function from a creep function or vice versa is to transfer the creep function into the Laplace domain. In…

Relaxation - spreadsheet solution to recursive algorithm

I am setting up a simple model that uses recursion to iterate between known constraints - relaxation, in other words. I need a spreadsheet that allows: A0 50 A1 =(A0+A2)/2 A2 =(A1+A3)/2 A3 =(A2+A4)/2 A4 100 It should be simple, but OpenOffice…
