HeaTrace: A Parametric Design‐to‐Fabrication Workflow for Thermally Programmable Soft Robots
Advanced Intelligent Systems, EarlyView.A programmable thermal actuation workflow enables soft robots to be designed and fabricated with embedded heaters that drive multiple responses. By combining performance‐driven heater design with multimaterial fabrication, the system supports thermally triggered shape change, stiffness tuning, and thermochromic visual response, as demonstrated through ...

Algebraic methods for chromatic polynomials [PDF]
, 2003 The chromatic polynomials of certain families of graphs can be calculated by a transfer matrix method. The transfer matrix commutes with an action of the symmetric group on the colours.

Chromatic Index of Hypergraphs and Shannon’s Theorem
European Journal of Combinatorics, 2000 Let \(G\) be a multigraph without loops and let \(\chi '(G)\) be its chromatic index. A classical theorem of Shannon states that \(\chi '(G)\leq \lfloor \frac{3}{2}\Delta (G)\rfloor \). For a hypergraph \(H\), the 2-section of \(H\) is a multigraph \([H]_{2}\) without loops on the vertex set \(V(H)\), with \(k\) parallel edges between vertices \(u ...

The irregular chromatic index of trees
, 2013 A graph G is locally irregular if adjacent vertices of G have distinct degrees. An edge colouring of G is locally irregular if each of its colours induces a locally irregular subgraph of G. The irregular chromatic index of G refers to the least number of

Strong chromatic index of subcubic planar multigraphs
, 2016 The strong chromatic index of a multigraph is the minimum k such that the edge set can be k-colored requiring that each color class induces a matching. We verify a conjecture of Faudree, Gyarfas, Schelp and Tuza, showing that every planar multigraph with
