Quantitative analysis of three artificial neural networks show that instability is commonly observed in all networks...

We propose combining the two concepts by using multichannel measurements of wavefield and its derivatives in the compressive sensing framework and solving the joint sparse recovery problem. Our preliminary results show that the multichannel CS approach is more reliable than the single channel CS...

The underwater drone removed the weather factor that correspondingly limits barnacle cleaning with traditional workboat-based tools, and thereby prevented a full spread recovery. The collective anti-barnacle mitigations enabled the survey to be completed ahead of schedule...
