A Field Programmable Gate Array‐Assisted Optoelectronic Emulator for Photonic Neuromorphic Computing
Advanced Intelligent Systems, EarlyView.This work presents a hybrid optoelectronic architecture using field‐programmable‐gate‐array‐controlled optical components for multiplication operations. Data are encoded via electro‐optic modulator, weights are programmed via a variable optical attenuator, and results are detected by a photodetector.

Morphology and Mach Number Dependence of Subsonic Bondi–Hoyle Accretion
The Astrophysical JournalWe carry out three-dimensional computations of the accretion rate onto an object (of size R _sink and mass m ) as it moves through a uniform medium at a subsonic speed v _∞ . The object is treated as a fully absorbing boundary (e.g., a black hole).

A Relaxation Scheme for the Simulation of Low Mach Number Flows [PDF]
, 2017 A scheme for the simulation of inviscid flows with low Mach number is derived. The scheme is built on a relaxation system and it is based on a linear implicit time discretization. The advective part is discretized by a convex combination of upwind and centered schemes, in order to recover the correct limit when the Mach number goes to zero.

Flight measured and calculated exhaust jet conditions for an F100 engine in an F-15 airplane [PDF]
The exhaust jet conditions, in terms of temperature and Mach number, were determined for a nozzle-aft end acoustic study flown on an F-15 aircraft. Jet properties for the F100 EMD engines were calculated using the engine manufacturer's specification deck.
