Knowledge transfer: An information theory perspective by Sudhindra, S., Ganesh, L., Kaur, Arshinder

“…This paper proposes a theoretical model of KT that explains organizations' choice of KT mechanisms in terms of the tacitness of knowledge being shared and the corresponding information content. Shannon's entropy, an information theoretical concept, has been used to define the constructs of tacitness and information content and explain their influence on the choice of the corresponding KT mechanisms. …”

Automatic detection of marine mammals using information entropy by Erbe, Christine, King, A.

“…Even though therehas been previous research on optimizing automatic detectors for specific calls or specific species,the detection of any type of call by a diversity of marine mammal species still poses quite achallenge—and one that is faced more frequently as the scope of passive acoustic monitoring studiesand the amount of data collected increase. Information Shannon entropy measures the amount ofinformation in a signal. …”

Identification of de-bonding between steel bars and concrete using wavelet techniques: Comparative study by Ou, G., Ying, W., Hao, Hong, Zhu, X.

“…This paper uses the wavelet transform combined with the wavelet packet decomposition, component energy and Shannon entropy to analyze the experimental results. The results demonstrate that both damage index and relative entropy are sensitive to the existence of de-bonding damage and change linearly with de-bonding length when there is only a single de-bonding damage, while energy and entropy distribution are largely influenced by the property of the excitation signal. …”
