The downhill plow problem with multiple plows
Journal of the Operational Research Society, 2014In winter, a common problem is to determine a set of routes for snow plows that minimize the maximum route length. Typically, this is modelled as an arc routing problem. We begin with a variant that is motivated by the fact that deadhead travel over streets is significantly faster than the time it takes to plow the street.

Optimized design for the plow of a submarine plowing trencher
Journal of Marine Science and Application, 2013The plow of the submarine plowing trencher is one of the main functional mechanisms, and its optimization is very important. The design parameters play a very significant role in determining the requirements of the towing force of a vessel. A multi-objective genetic algorithm based on analytical models of the plow surface has been examined and applied ...

Plowing and non-plowing under Nordic conditions
Soil and Tillage Research, 1991Abstract Certain aspects of plowing and non-plowing which are particularly important under Nordic conditions, or where experiences may differ from those acquired under Middle European or British conditions, are discussed. These include the control of couchgrass ( Agropyron repens ), technical problems with crop residue, and the suitability of ...

Transactions of the American Institute of Electrical Engineers, 1939
A METHOD of protection of submarine cables by placement “underground” was described during the process of its development in an article written for Electrical Engineering in May 1938. The work then projected has since been successfully carried out, and the first cables scheduled to be plowed under, to protect them from being fouled by fishing gear ...
