Periodic Rigidity on a Variable Torus Using Inductive Constructions

In this paper we prove a recursive characterisation of generic rigidity for frameworks periodic in the plane with respect to a partially variable lattice. We follow the approach of modelling periodic frameworks as frameworks on a torus and use the language of gain graphs for the finite counterpart of a periodic graph. In this setting we employ variants of the Henneberg operations used frequentl...

Flexible Inductive Transducer with Magnetic Resistance Influenced by Variable Overlap Area

Inductive transducers for measuring displacement are divided into two groups according to their measurement range. A variable air-gap type transducer is widely used for a measurement small range. A conventional variable air-gap type transducer has high sensitivity but lacks a linear measurement range. The air gap is also increased to maintain linearity as the measurement range increases, which ...

Non-deterministic inductive definitions

We study a new proof principle in the context of constructive ZermeloFraenkel set theory based on what we will call “non-deterministic inductive definitions”. We give applications to formal topology as well as a predicative justification of this principle.
