AC/DC current ratio in a current superimposition variable flux reluctance machine
Open Physics, 2018 We have proposed a current superimposition variable flux reluctance machine for traction motors. The torque-speed characteristics of this machine can be controlled by increasing or decreasing the DC current.

Faster Deterministic Fully-Dynamic Graph Connectivity [PDF]
, 2012 We give new deterministic bounds for fully-dynamic graph connectivity. Our data structure supports updates (edge insertions/deletions) in $O(\log^2n/\log\log n)$ amortized time and connectivity queries in $O(\log n/\log\log n)$ worst-case time, where $n$

A Stochastic Decoder for Neural Machine Translation [PDF]
, 2018 The process of translation is ambiguous, in that there are typically many valid trans- lations for a given sentence. This gives rise to significant variation in parallel cor- pora, however, most current models of machine translation do not account for ...

Equilibrium mechanism between dc voltage and ac frequency for ac–dc interlinking converters
iEnergy, 2022 The equilibrium between dc bus voltage and ac bus frequency (Udc-f equilibrium) is the algorithm core of unified control strategies for ac-dc interlinking converters (ILCs), because the equilibrium implements certain mechanism.
