Quotient Inductive-Inductive Types [PDF]

open access: yes, 2018
Higher inductive types (HITs) in Homotopy Type Theory (HoTT) allow the definition of datatypes which have constructors for equalities over the defined type. HITs generalise quotient types and allow to define types which are not sets in the sense of HoTT (i.e.

Signatures and Induction Principles for Higher Inductive-Inductive Types

open access: yesLogical Methods in Computer Science, 2020
Higher inductive-inductive types (HIITs) generalize inductive types of dependent type theories in two ways. On the one hand they allow the simultaneous definition of multiple sorts that can be indexed over each other. On the other hand they support equality constructors, thus generalizing higher inductive types of homotopy type theory.

Inductive-Inductive Definitions [PDF]

open access: yes, 2010
We present a principle for introducing new types in type theory which generalises strictly positive indexed inductive data types. In this new principle a set A is defined inductively simultaneously with an A-indexed set B, which is also defined inductively.

Asymptotic behaviour of the inductance coefficient for thin conductors [PDF]

open access: yes, 2002
We study the asymptotic behaviour of the inductance coefficient for a thin toroidal inductor whose thickness depends on a small parameter $\eps>0$.

Inductive * -Semirings

open access: yesBRICS Report Series, 2000
One of the most well-known induction principles in computer science<br />is the fixed point induction rule, or least pre-fixed point rule. Inductive <br />*-semirings are partially ordered semirings equipped with a star operation<br />satisfying the fixed point equation and the fixed point induction rule for<br />linear terms ...

Research on an Axial Flux PMSM with Radially Sliding Permanent Magnets

open access: yesEnergies, 2015
Axial flux permanent-magnet synchronous machines (PMSMs) are very suitable candidates for the power train of electric vehicles (EVs) due to high power density and high efficiency.

Improved Formulae for the Inductance of Straight Wires

open access: yesAdvanced Electromagnetics, 2014
The best analytical formulae for the self-inductance of rectangular coils of circular cross section available in the literature were derived from formulae for the partial inductance of straight wires, which, in turn, are based on the well-known formula ...

Induction Machine-Based EV Vector Control Model Using Mamdani Fuzzy Logic Controller

open access: yesApplied Sciences, 2022
The substantial rise in the demand for electric vehicles (EVs) has emphasized an environment-friendly and intelligent design for speed control strategies. In this paper, a Mamdani fuzzy logic controller (MFLC) was proposed to vigorously control the speed
