Virtualization can provide significant benefits in data centers by enabling virtual machine migration to eliminate hotspots. We present Sandpiper, a system that automates the task of monitoring and detecting hotspots, determining a new mapping of physical to virtual resources and initiating the necessary migrations. Sandpiper implements a black-box approach that is fully OSand application-agnos...

Military Operations Research makes extensive use of large complex simulation models. These simulation models are often black-boxes; i.e. they are opaque and incomprehensible. A considerable effort is involved in commissioning a new model into service. We characterise this activity as the construction of gray-box approximate causal models of the functional behaviour of black-box simulation softw...

introduction: rural areas are affected by globalization and one of the globalization commitments. wto accession creates both benefits and expenditures for countries especially rural societes in new member, but preponderance of created benefits and expenditures depends on country bargaining power in negotiation process and agreement acceptation. as there is not independent and separate agreement...

We construct a bijection between the state of box-ball system with box capacity L and pair two sequences. During time evolution, one sequences moves at speed 1, other follows rules one, which can be linearized by Kerov–Kirillov–Reshetikhin (KKR) bijection. Our method applied to including negative value or greater than capacity.
