    THE BIBLE, OPEN AND DISTANCE EDUCATION AND LEARNING, AND SPIRITUALITY: POSSIBILITIES IN A POST-SECULAR TIME by C. Lombaard

    Published 2021-06-01
    “… To teach the Bible to students of theology at tertiary level (university/seminary/(Bible/Mission) college) is at the best of times fraught with difficulties. Combining the initially often intellectually a-critical religious sentiments of students with the demands of biblical/Old Testament/New Testament studies as science (language skills, exegetical methodologies, critical theories, hermeneutics of understanding and of relevance) is characterised by some difficulties, which lead to various and some extreme reactions among students. …”

    Secrecy analysis for orthogonal time frequency space technique based LEO satellite communication by Zan LI, Junfan HU, Bing LI, Jia SHI, Jiangbo SI

    Published 2021-08-01
    “…In order to improve the security performance of low earth orbit (LEO) satellite downlink communication system, a cooperative UAV was employed to send jamming signals against the eavesdroppers.In particular, the downlink transmission was based on the orthogonal time frequency space (OTFS) technique to combat the severe Doppler effect caused by the high mobility of the LEO satellite.The closed form expression for the security outage probability (SOP) was derived at the legitimate receiver, where a novel moment matching approach was used for finding a summed probability distribution function (PDF) of the shadowed-Rician (SR) distributed terms.Simulation results prove that the SOP performance advantage of the downlink LEO satellite communication achieved by OTFS over OFDM scheme, and show the effectiveness of employing unmanned aerial vehicle (UAV) jammer in terms of enhancing secrecy transmission.…”
