A unified framework for kinematic simulation of rigid-foldable structures
Published on 2026-06-19 by @OXFORD
Abstract: AbstractOrigami-inspired structures with rigid panels now span thick, kirigami, and multi-sheet realizations, making unified kinematic analysis essential. Yet a generalized pipeline that systematically translates their geometric definitions into mathematical loop-closure constraints has been lacking. We present an automated approach that constructs the Pfaffian constraint matrix directly from pattern-level geometric data for a broad class of rigid-foldable structures (RFSs). From a minimally ext[...]
Our summary: The paper presents a unified framework for kinematic simulation of rigid-foldable structures. It automates the construction of the Pfaffian constraint matrix from geometric data. The framework enhances the analysis of deployment and folding motions while reducing errors in constraint calculations.

Attention-guided transformer architecture for fine-grained style representation in design systems
Published on 2026-05-01 by @OXFORD
Abstract: AbstractInterior design style recognition presents a challenging computational problem due to fine-grained inter-style similarities, complex spatial arrangements, and strong variability in materials, lighting, and layout. From a computational design and engineering perspective, accurately modelling such stylistic variations is essential not only for classification, but also for enabling semantic representation, retrieval, and analysis of design cases within data-driven design systems. However, e[...]
