NSF Forecast Space Weather,Power Grid Pipelines Satellites
2017/12/19
While Earth's weather reports center on precipitation, temperature, wind direction and velocity, and humidity, space weather forecasts attempt to predict activity that occurs on the sun -- and how the...
Finite-State Chart Constraints for Reduced Complexity Context-Free Parsing Pipelines
Finite-State Chart Reduced Complexity Parsing Pipelines
2015/9/10
We present methods for reducing the worst-case and typical-case complexity of a context-free parsing pipeline via hard constraints derived from finite-state pre-processing. We perform O(n) predictions...
Squibs and Discussions Pipelines and Size Constraints
Discussions Pipelines Size Constraint
2015/8/25
Some types of documents need to meet size constraints, such as fitting into a limited number of
pages. This can be a difficult constraint to enforce in a pipelined natural language genera...

A simple two-dimensional mathematical model capable of describing the interactions taking place in the bulk fluid and biofilm between sulfate reducing bacteria (SRB), substrates and biocide agents wa...
Evaluation of Distance Measurement Accuracy by Odometer for Pipelines Pigs
Odometer Perimeter INS pipeline
2009/7/28
High precision is essential in the localization of anomalies (laminations, corrugations, corrosion, stress, blows, etc.) by the pig inspection device in any pipeline. The problem of distance measurem...
VIV analysis of pipelines under complex span conditions
boundary condition (BC) fatigue limit state (FLS) force model (FM) kilometer post (KP) mode shape natural frequency response model (RM) vortex-induced vibration (VIV) ultimate limit state (ULS) unit stress
2011/9/13
Spans occur when a pipeline is laid on a rough undulating seabed or when upheaval buckling occurs due to constrained thermal expansion. This not only results in static and dynamic loads on the flowlin...
