Joining of Oxide Dispersion-Strengthened Steel Using Spark Plasma Sintering

Cyril Cayron

Difficulties with joining oxide dispersion-strengthened (ODS) steels using classical welding processes have led to the development of alternative joining techniques such as spark plasma sintering (SPS). SPS, which is classically employed for performing sin ...

Jumping the ORDER BY Barrier in Large-Scale Pattern Matching

Daniel Lupei

Event-series pattern matching is a major component of large-scale data analytics pipelines enabling a wide range of system diagnostics tasks. A precursor to pattern matching is an expensive ``shuffle the world'' stage wherein data are ordered by time and s ...
