On (strong) proper vertex-connection of graphs

open access: yes, 2015
A path in a vertex-colored graph is a {\it vertex-proper path} if any two internal adjacent vertices differ in color. A vertex-colored graph is {\it proper vertex $k$-connected} if any two vertices of the graph are connected by $k$ disjoint vertex-proper

Wood Crib with PVC Cables: Compartment Fire Toxicity [PDF]

open access: yes, 2016
Electrical cable fires may occur as part of a fire load and this was simulated using a pine wood crib fire in a compartment with PVC cables laid as a single layer on top of the crib. The aim was to trace the HCL yield under a mixed fuel compartment fire.
