Skeleton crew

I t pays to have a backup project in case your main research stalls. That's what Alan Hall (now at University College London) and colleagues learned when they set aside their studies on the protein ras and switched to its cousin rho. Their work (starting with Paterson et al., 1990) revealed that rho and related proteins were key regulators of the cell's actin cytoskeleton, and it set the stage ...

Technologies for Low-Crew/No-Crew Ships

Related transport engineering sciences show spectacular progress in automation reviving a discussing of unmanned ships using Artificial Intelligence technologies particularly for combatants. The nautical tasks could be largely automated and the commercial expert systems for automatic navigation including collision and grounding avoidance are on the market. Damage control appears to be another p...

A crew of patches

Given the present obsession with pattern formation, it is hard to appreciate that 30 years ago there were but few eccentrics who knew what the words meant. In those days, any who tried to understand patterns searched throughout zoology and botany for colleagues who shared their interest. Topics of research included the spacing of hairs on sheep or of stomata in plants, and the orientation of in...

4 Airline Crew Scheduling

Crew scheduling can be defined as the problem of assigning a group of workers (a crew) to a set of tasks. The crews are typically interchangeable , although in some cases different crews possess different characteristics that affect which subsets of tasks they can complete. Crew scheduling problems appear in a number of transportation contexts. Examples include bus and rail transit, truck and r...
