Mathematics of Operations Research, 2022 We introduce the pipeline intervention problem, defined by a layered directed acyclic graph and a set of stochastic matrices governing transitions between successive layers. The graph is a stylized model for how people from different populations are presented opportunities, eventually leading to some reward.

To pipeline or not to pipeline, that is the question
CoRR, 2020 In designing query processing primitives, a crucial design choice is the method for data transfer between two operators in a query plan. As we were considering this critical design mechanism for an in-memory database system that we are building, we quickly realized that (surprisingly) there isn't a clear definition of this concept.

Pipeline morphing and virtual pipelines [PDF]
, 1997 Pipeline morphing is a simple but effective technique for reconfiguring pipelined FPGA designs at run time. By overlapping computation and reconfiguration, the latency associated with emptying and refilling a pipeline can be avoided. We show how morphing can be applied to linear and mesh pipelines at both word-level and bit-level, and explain how this ...

Localization development of filter elements for natural gas stations
You-qi chuyun, 2021 For the fact that over 90% filter elements of stations along the long-distance gas pipeline were imported, filter elements with multiple particle intercepts and coalescence-separation characteristics were developed through selecting the preferred filter ...

Test on the degaussing technology used in the welding of China-Russia Eastern Gas Pipeline
You-qi chuyun, 2020 During the construction, rerouting and maintenance & repairing of long-distance pipelines, the phenomenon of magnetic partial blowing often occurs at pipeline junctions, which leads to the deviation of electric arc in the process of welding operation. As

Feasibility of eddy current inline inspection for crack-like defects of oil and gas pipelines
You-qi chuyun, 2021 The crack-like defects of oil and gas pipelines, especially the crack-like defects on the inner surface, are the main factors leading to pipeline failure.

, 2016 A pipeline network can potentially be attacked at any point and at any time, but such an attack takes a known length of time. To counter this, a Patroller moves around the network at unit speed, hoping to intercept the attack while it is being carried out. This is a zero sum game between the mobile Patroller and the Attacker, which we analyze and solve
