CE 4240/5240 - Homework #2 data dictionary

square_infrastructure_image.png
  128 x 128 grayscale square bridge image for the eigenvalue/image reconstruction problem.

square_infrastructure_image_matrix.csv
  Same image as a 128 x 128 numeric matrix scaled to [0,1].

time_series_noisy.csv
  Column 1: time_min. Columns 2-17: 16 noisy infrastructure sensor time series, sampled every 10 minutes for 5 days.

traffic_incidence.csv
  14 x 20 directed node-edge incidence matrix B. Convention: +1 at edge tail, -1 at edge head.

traffic_injections.csv
  14 x 1 nodal injection vector s satisfying B q = s. Positive = net external inflow; negative = net withdrawal.

traffic_edges.csv
  Edge ID, tail node, and head node for each of the 20 links.

traffic_measurements.csv
  Seven measured link flows (edges 14-20), used with flow conservation to resolve the loop-flow degrees of freedom.

module2_data.mat
  Convenience MATLAB file containing the same numerical data. CSV/PNG files are the primary cross-platform files.
