How Does Safety Stack Up ?

SH&E PROFESSIONALS have a vested interest in knowing more about top-level management—most of whom determine what resources are designated for safety within organizations. By knowing more about these managers’ perceptions of safety, an SH&E professional may be better equipped to negotiate for valued resources. For example, suppose you know that top-level managers within your industry think that ...

Dielectric elastomer generators that stack up

This paper reports the design, fabrication, and testing of a soft dielectric elastomer power generator with a volume of less than 1 cm. The generator is well suited to harvest energy from ambient and from human body motion as it can harvest from low frequency (sub-Hz) motions, and is compact and lightweight. Dielectric elastomers are highly stretchable variable capacitors. Electrical energy is ...

Complexity of the FIFO Stack-Up Problem

We study the combinatorial FIFO stack-up problem. In delivery industry, bins have to be stacked-up from conveyor belts onto pallets with respect to customer orders. Given k sequences q1, . . . , qk of labeled bins and a positive integer p, the aim is to stack-up the bins by iteratively removing the first bin of one of the k sequences and put it onto an initially empty pallet of unbounded capaci...
