How to recycle your facets
We show how to transform any inequality defining a facet of some 0/1-polytope into an inequality defining a facet of the acyclic subgraph polytope. While this facet-recycling procedure can potentially be used to construct ‘nasty’ facets, it can also be used to better understand and extend the polyhedral theory of the acyclic subgraph and linear ordering problems.
متن کاملHow to Recycle Random Bits
We show that modified versions of the linear congruential generator and the shift register generator are provably good for amplifying the correctness of a probabilistic algorithm. More precisely, if r random bits are needed for a BPP algorithm to be correct with probability at least 2/3, then O(r + k) bits are needed to improve this probability to 1 − 2−k. We also present a different pseudo-ran...
متن کاملRE: REempower and REcycle
This paper briefl y presents two concepts of “RE” (1) re-empowering individuals using personal mobile technology reconstructed as measurement instruments and (2) re-cycle as a design constraint for extending a product’s usable lifetime. In the fi rst example we demonstrate the integration of simple low-cost, low-power air quality sensors attached to a mobile phone. In the re-cycle case, we demo...
متن کاملTo Recycle or Not to Recycle? An Intergenerational Approach to Nuclear Fuel Cycles
This paper approaches the choice between the open and closed nuclear fuel cycles as a matter of intergenerational justice, by revealing the value conflicts in the production of nuclear energy. The closed fuel cycle improve sustainability in terms of the supply certainty of uranium and involves less long-term radiological risks and proliferation concerns. However, it compromises short-term publi...
متن کاملImproving Cyclone Efficiency by Recycle and Jet Impingement Streams
In this paper a new process is presented for improving efficiency of cyclone de-dusting systems. The cyclone is coupled with a specially designed cylindrical chamber which includes a rotating tube inside it with air impinging nuzzles, drilled on the peripheral surface of the tube. The nuzzles help in pushing and throwing the particles to the outer radius distances during downward flow of du...
