Photoelastic force measurements in granular materials
Karen E. Daniels, Jonathan E. Kollmer, James G. Puckett
Photoelastic techniques are used to make both qualitative and quantitative measurements of the forces within idealized granular materials. The method is based on placing a birefrin…
Counting Finite Index Subrings of
Stanislav Atanasov, Nathan Kaplan, Benjamin Krakoff +1
We count subrings of small index of , where the addition and multiplication are defined componentwise. Let denote the number of subrings of index . For an…
Measurements of the Separated Longitudinal Structure Function F_L from Hydrogen and Deuterium Targets at Low Q^2
V. Tvaskis, A. Tvaskis, I. Niculescu +100
Structure functions, as measured in lepton-nucleon scattering, have proven to be very useful in studying the quark dynamics within the nucleon. However, it is experimentally diffic…
Evolution of network architecture in a granular material under compression
Lia Papadopoulos, James Puckett, Karen E. Daniels +1
As a granular material is compressed, the particles and forces within the system arrange to form complex heterogeneous structures. Force chains are a prime example and are thought…
On Asymptotic Approximate Groups of Integers
Bela Bajnok
Let be a positive integer, and let be a nonempty finite set of at least two integers. We let denote the {\em asymptotic -covering number} of , that i…
