Connectivity Issues for Ultraviolet UV-C Networks
(2011)This paper focuses on the connectivity issues of a non-line-of-sight (NLOS) optical wireless network operating in the ultraviolet UV-C spectral region. NLOS UV-C transmitters have a limited effective coverage and, hence, ... -
Improvement of fatigue crack growth resistance by controlled overaging in 2024-T3 aluminium alloy
(2014)A controlled overaging process is proposed to increase region II fatigue crack propagation resistance of 2024-T3 aluminium alloy. Overaging was achieved by subjecting the material from the initial T3 state to heat treatment ... -
Node Isolation Probability for Serial Ultraviolet UV-C Multi-hop Networks
(2011)Non-line-of-sight optical wireless transmission, operated in the unlicensed ultraviolet UV-C band, has been recently suggested as an alternative means of communication. However, due to limited coverage, relayed UV-C networks ...
