    Performance analysis and power optimization for FH secure communication under frequency and phase mismatch by Changqing SONG, Hongzhi ZHAO, Lizhi QIN, Shihai SHAO

    Published 2022-09-01
    “…The artificial noise (AN) shielded frequency hopping (FH) secure communication can counteract electromagnetic interference and wiretapping, but its carrier frequencies change rapidly within a wide bandwidth which will raise the level of carrier frequency offset and phase noise, yielding AN cancellation performance degradation.To tackle this, the signal distortion caused by frequency and phase mismatch (FPM) was mathematically modeled, the AN cancellation performance was evaluated via signal-to-noise ratio, and the system secrecy was scaled via secrecy capacity.On basis of this, the optimal power allocation scheme for AN and confidential signal was designed, and the scheme was expanded according to the FPM level and the propagation channel quality.Numerical simulations verify that FPM can significantly degrade the noise cancellation performance and system secrecy, and to counteract this, the power ratio of AN to confidential signals should decrease with an increasing FPM.…”

    Framing of Civil Society Organizations’ Communication on Facebook: Examining the Impact on Audience Engagement in Norway by Enjolras Bernard

    Published 2024-11-01
    “…This paper aims to examine how cognitive or topical framing and moral foundational framing interact in predicting public engagement with CSOs’ communication about climate change on Facebook. To this end, several computational methods – including topic modeling, semantic network analysis, and automatic text processing based on a Moral Foundations dictionary – are combined, using data gathered on Facebook. …”

    Patient and caregiver perspectives of select non-communicable diseases in India: A scoping review. by Sindhu Nila, Eliza Dutta, S S Prakash, Sophy Korula, Anu Mary Oommen

    Published 2024-01-01
    “…Repeated visits to crowded centres, drug refill issues, unavailability of specific services in government facilities, and expensive private care characterised diabetes care, while cancer care involved delayed diagnosis and treatment, communication, and pain management issues.<h4>Conclusions</h4>There is a need for robust approaches and standardised tools to measure responsiveness of the healthcare system to patient needs, across geographical and population subgroups in India. …”
