On the Suitability of Vibration Acceptance Criteria of Process Pipework
( Hindawi , 2022 , Article)The risk of vibration-induced fatigue in process pipework is usually assessed through vibration measurements. For small-bore pipework, integrity personnel would measure the vibration of the pipework and refer to widely ... -
On the synergistic benefits of alternating CSIT for X channel within a four-symbol channel extension
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, we investigate the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel with alternating channel state information at the transmitters (CSIT). Three cases are considered for ... -
On the synergistic corrosion inhibition and polymer healing effects of polyolefin coatings modified with Ce-loaded hydroxyapatite particles applied on steel
( Elsevier Ltd , 2021 , Article)pH-sensitive hydroxyapatite particles were loaded with cerium ions (Ce-HAP) and incorporated into polyolefin coatings applied on carbon steel. The Ce-modified hydroxyapatite particles were characterized by scanning electron ... -
