Every flow modification accessory is a MaterialArtifact that bears a FlowModificationFunction and participates in processes that alter fluid flow characteristics.
First-Order Logic TheoryTeoria em Lógica de Primeira Ordem
[Definition]∀x (FlowModificationAccessory(x) ↔ MaterialArtifact(x) ∧ ∃f (FlowModificationFunction(f) ∧ bearerOf(x,f))) — Steps 1–3: genus + identity-giving function
[Function axiom: FlowModificationFunction]∀f (FlowModificationFunction(f) → ∀p (realizedIn(f,p) → FlowModificationProcess(p)) ∧ ∃p (FlowModificationProcess(p) ∧ realizedIn(f,p))) — Step 1: ∀ preserves type-type identity; ∃ rules out vacuous functions never realised
[Process participation signature]∀x ∀f ((FlowModificationAccessory(x) ∧ FlowModificationFunction(f) ∧ bearerOf(x,f)) →
∃m (FluidPortion(m) ∧ participatesIn(m,f)) ∧
∃e (FluidPortion(e) ∧ participatesIn(e,f)) ∧
processType(f,FlowRegulation)) — Step 5: typed participants in the realising process
