The work done here is primarily a wrapper function written to separate some of the more difficult-to-use glpkAPI functionality from the end-user. The user, when prompted, selects the appropriate configuration of the .mod file to the task (for example, output-oriented CRS), and the data file, as a .dat. The function then loads the required glpkAPI library, and carries forward the model. It allocates the problem and workspace, reads the model file and data file the user selects, builds the problem, and solves it. The function returns primal values, and, if dual = TRUE is selected, also returns dual weights.

In sonar array processing, a challenging problem is the estimation of the data covariance matrix in the presence of moving targets in the water column, since the time interval of data local stationarity is limited. This work describes an eigenvector-based method for proper data segmentation into intervals that exhibit local stationarity, providing data-driven higher bounds for the number of snapshots available for computation of time-varying sample covariance matrices. Application of the test is illustrated with simulated data in a horizontal array for the detection of a quiet source in the presence of a loud interferer.

Systems Science Friday Noon Seminar Series
Tools have long been available for improving decision making, yet people who have knowledge of these tools seem reluctant to use them. I consider multiple reasons why this might be so and consider multiple solutions, then present what I believe to be the world's most user-friendly decision aid, which is now nearly ready for beta testing and available at no cost at http://wisedecider.net.
Wise Decider is believed to be unique in having the following features:
- A creative thinking guide and a critical thinking guide that provide context-sensitive advice for problem structuring, evaluation, and implementation.
- A decision table with cells …
