Transient modelling of doubly‐fed induction generator based wind turbine on full operation condition and rapid starting period based on low voltage ride‐through testing

open access: yesIET Renewable Power Generation, 2021
Transient simulation model of doubly‐fed induction generator‐based wind turbine has a complex model structure and considerable control parameters. An accurate simulation model is especially important for studying the static and transient characteristics ...

Sampling assumptions in inductive generalization [PDF]

open access: yesCognitive Science, 2011
Inductive generalization, where people go beyond the data provided, is a basic cognitive capability, and it underpins theoretical accounts of learning, categorization, and decision making. To complete the inductive leap needed for generalization, people must make a key ‘‘sampling’’ assumption about how the available data were generated. Previous models

Generic Fibrational Induction [PDF]

open access: yesLogical Methods in Computer Science, 2012
This paper provides an induction rule that can be used to prove properties of data structures whose types are inductive, i.e., are carriers of initial algebras of functors. Our results are semantic in nature and are inspired by Hermida and Jacobs' elegant algebraic formulation of induction for polynomial data types. Our contribution is to derive, under

Inductively generated formal topologies

open access: yesAnnals of Pure and Applied Logic, 2003
This paper introduces the very useful concept of inductively generated formal topology (without or with the positivity predicate) in a predicative framework. Formal topology was introduced by P. Martin-Löf and G. Sambin to provide a predicative representation of the concept of locale and open locale [see \textit{G.
