Even circuits in planar graphs

open access: yesJournal of Combinatorial Theory, Series B, 1981
AbstractWe prove that a planar graph can be partitioned into edge-disjoint circuits of even length, if and only if every vertex has even valency and every block has an even number of edges.

Optimized absorbing boundary conditions for the analysis of planar circuits using the finite difference time domain method [PDF]

open access: yes, 1993
It is shown that the description of absorbing boundary condition algorithms (ABCs) in terms of single incident plane waves does not provide sufficient information for choosing the best ABC for planar waveguide termination.

Carboxylic‐Acid Functionalized Multiwalled Carbon Nanotube‐Alkane‐Based Resistive Temperature Sensor for Cold Chain Applications

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the
