Quasi-4-Connected Components [PDF]
We introduce a new decomposition of a graphs into quasi-4-connected components, where we call a graph quasi-4-connected if it is 3-connected and it only has separations of order 3 that separate a single vertex from the rest of the graph.

On the existence of a connected component of a graph [PDF]
We study the reverse mathematics and computability of countable graph theory, obtaining the following results. The principle that every countable graph has a connected component is equivalent to $\mathsf{ACA}_0$ over $\mathsf{RCA}_0$.

Object Delineation by κ-Connected Components [PDF]
The notion of “strength of connectedness†between pixels has been successfully used in image segmentation. We present extensions to these works, which can considerably improve the efficiency of object delineation tasks.

The Existence and Application of Unbounded Connected Components [PDF]
Let X be a Banach space and Cn a family of connected subsets of R×X. We prove the existence of unbounded components in superior limit of {Cn}, denoted by lim¯ Cn, which have prescribed shapes.

Research on performance of proton exchange membrane fuel cell with an innovative flow field
The mass transfer enhanced cathode flow field with little pressure loss is a key factor to proton exchange membrane fuel cell (PEMFC) design. A new type of cathode flow field incorporating ship-shaped baffles which enhances mass transfer while causes ...
