Parallel load and query processing in a distributed array database
… of these types of data is skewed and sparse, rather than dense and uniform. As input data sizes continue to grow at a rapid rate, main memory and storage capacity become bottlenecks on single machines. Thus, we look to distributed array databases as a long term solution for managing …

Flow and solute transport in random cylinder arrays : a model for emergent aquatic plant canopies
… and lateral dispersion of passive solute in arrays of randomly-distributed cylinders, a model for emergent, rigid aquatic plants. Mean drag per cylinder length normalized by the mean interstitial fluid velocity and viscosity increases linearly with cylinder Reynolds number. In contrast to the …

Development of bio-inspired distributed pressure sensor arrays for hydrodynamic sensing applications
… requirements of commercial sensors lead to sparse arrays and substantial gaps in the characterization of the flow field. To address the challenges associated with obtaining spatially-dense pressure measurements on curved surfaces in marine environments, a new waterproof and conformal …

Architectures and system design for digitally-enhanced antenna arrays
… design of the analog hardware aspects of the arrays. The class of digitally-enhanced hardware has recently emerged, wherein "digitally aware" design approaches are used for the purpose of alleviating the high cost and complexity of sophisticated analog devices. Emergent trends in millimeter …
