Storage Capacity of the Linear Associator: Beginnings of a Theory of Computational Memory
… dynamics of the linear-associator to discern its storage capacity and classification capabilities as they scale with system size. To determine storage capacity, a set of M vector-pairs called "items" are stored in an associator with N connection-weights. The number of bits of information stored by …

Storage capacity and injection rate estimates for CO₂ sequestration in deep saline aquifers in the conterminous United States
… In this work, we develop simple models of storage capacity and injection rate at the basin scale. We develop a storage capacity model that calculates how much CO₂ an aquifer can store based on how the plume of injected CO₂ migrates. We also develop an injection rate model that calculates …
