Heuristics for the Design of Thick Composite Cylinders

A heuristic is proposed for a problem that occurs in the design of thick composite cylinders: the selection of the angles of wrap of all the layers forming a cylinder for given material properties and layer thicknesses. The heuristic consists of a local search algorithm that improves on a given initial design by modifying the angle of a single layer in each iteration. Each design is evaluated b...

Thermoplastic Materials Applications in Radiation Therapy.

This is an example of the use of thermoplastic materials in a high-tech medicine field, oncology radiation therapy, in order to produce the rigid masks for positioning and immobilization of the patient during simulation of the treatment procedure, the imaging verification of position and administration of the indicated radiation dose. Implementation of modern techniques of radiation therapy is ...

Deep sea in deep trouble?

Ahead of the imminent start of the industrial exploitation of deep sea resources, an EU report finds that scientific knowledge and understanding of this environment and its ecosystems still fall short of what would be needed for a sustainable use.
