Rapid Design and Fabrication of Body Conformable Surfaces with Kirigami Cutting and Machine Learning

Advanced Science, EarlyView.
By integrating the principles of kirigami cutting and data‐driven modeling, this study aims to develop a personalized, rapid, and low‐cost design and fabrication pipeline for creating body‐conformable surfaces around the knee joint. This pipeline presents a balanced trade‐off between conformability performance and cost for personalizing wearables, thus

Sub‐Unit‐Cell Logic Governs Transport in TPMS Architectures

Advanced Science, EarlyView.
ABSTRACT Next‐generation energy, thermal, and chemical systems require architectures capable of highly efficient transport across multiple length scales. Triply periodic minimal surfaces (TPMS), first conceptualized in 1865, offer inherently scalable geometries with exceptional transport potential, yet mechanistic links between topology and performance

Fractals in G-metric spaces

Applied Mathematical Sciences, 2013
The theory of iterated function systems (IFS) on complete metric spaces appears in almost all fractal based algorithms used for the purpose of compression of the images and their representation as well. Through a simple mathematical model, IFS technique provides an important tool for description and manipulation of the complex fractal attractors.
