IEEE transactions on industry applications, 2019 This paper presents a statistical methodology for detection of inter-turn short-circuit fault in asynchronous and synchronous machines. This methodology uses a correlation coefficient obtained from external magnetic field measured in the machine vicinity.

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

Parallelizing non-vectorizable loops for MIMD machines [PDF]
, 1990 Parallelizing a loop for MIMD machines can be described as a process of partitioning it into a number of relatively independent subloops. Previous approaches to partitioning non-vectorizable loops were mainly based on iteration pipelining which ...

Some undecidability results for asynchronous transducers and the Brin-Thompson group 2V [PDF]
, 2014 Using a result of Kari and Ollinger, we prove that the torsion problem for elements of the Brin-Thompson group 2V is undecidable. As a result, we show that there does not exist an algorithm to determine whether an element of the rational group R of ...
