Hardware acceleration of number theoretic transform for zk‐SNARK
Engineering Reports, EarlyView., 2023 An FPGA‐based hardware accelerator with a multi‐level pipeline is designed to support the large‐bitwidth and large‐scale NTT tasks in zk‐SNARK. It can be flexibly scaled to different scales of FPGAs and has been equipped in the heterogeneous acceleration system with the help of HLS and OpenCL.

Autonomous mode and parallel operation of an asynchronous generator with the electrical network [PDF]
E3S Web of ConferencesThis article explains that an asynchronous machine, like other electrical machines, can operate as a motor and generator due to the property of reciprocating motion and that an asynchronous generator is not different in design from an induction motor ...

Performance evaluation of a transformerless multiphase electric submersible pump system
The Journal of Engineering, 2014 Using of low-voltage variable-frequency drive followed by a step-up transformer is the most preferable way to feed an electrical submersible pump motor. The existence of long feeder between the motor and drive systems usually causes over-voltage problems

Exploring heterogeneity of unreliable machines for p2p backup
, 2013 P2P architecture is a viable option for enterprise backup. In contrast to dedicated backup servers, nowadays a standard solution, making backups directly on organization's workstations should be cheaper (as existing hardware is used), more efficient (as ...

Building high-level features using large scale unsupervised learning [PDF]
, 2012 We consider the problem of building high-level, class-specific feature detectors from only unlabeled data. For example, is it possible to learn a face detector using only unlabeled images?
