Designing Aluminum Alloys for a Recycling Friendly World
Recycling aluminum alloys has been shown to provide major economic benefits, as a result it is appropriate for the aluminum industry and the United States as a whole to identify, develop, and implement all technologies that will optimize the benefits of recycling. This paper will focus primarily alloy design for optimizing the reuse of recycled metal; this is both the most forward looking as we...
متن کاملStrategies For Aluminum Recycling: Insights From Material System Optimization
level, the primary decisions for a remelter involve composing alloy batches by carefully selecting and mixing various amounts of scrap and primary materials. Sorting provides added flexibility as well as complexity to these decisions by affording the secondary processor the opportunity to upgrade the materials which they have at hand. With sorting, the set of operational decisions include what ...
متن کاملRecycling gone bad: When the option to recycle increases resource consumption
In this study, we propose that the ability to recycle may lead to increased resource usage compared to when a recycling option is not available. Supporting this hypothesis, our first experiment shows that consumers used more paper while evaluating a pair of scissors when the option to recycle was provided (vs. not provided). In a follow-up field experiment, we find that the per person restroom ...
متن کاملRecycle of Random Sequences
The correlation between a random sequence and its transformed sequences is studied. In the case of a permutation operation or, in other word, the shuffling operation, it is shown that the correlation can be so small that the sequences can be regarded as independent random sequences. The applications to the Monte Carlo simulations are also given. This method is especially useful in the Ising Mon...
متن کاملAn Updated Evaluation of ReCycle
Process variation reduces a pipeline’s maximum attainable frequency by creating unbalance in the stage delays. As a result, the pipeline ends up cycling with a period close to that of the slowest pipeline stage. ReCycle was proposed in ISCA 2007 as a framework for comprehensively applying cycle time stealing to balance the stage delays under process variation, thereby allowing the pipeline to c...
