    Design and Optimization of Stacked Wideband On-Body Antenna with Parasitic Elements and Defected Ground Structure for Biomedical Applications Using SB-SADEA Method by Mariana Amador, Mobayode O. Akinsolu, Qiang Hua, João Cardoso, Daniel Albuquerque, Pedro Pinho

    Published 2025-01-01
    “…By using an AI-driven design approach, a self-adaptive Bayesian neural network surrogate-model-assisted differential evolution for antenna optimization (SB-SADEA) method to be specific, and a stacked structure having parasitic elements and a defected ground structure with 27 tuneable design parameters, the simulated impedance bandwidth of the on-body antenna was successfully enhanced from 150 MHz to 1.3 GHz, while employing a single and simplified body model in the simulation process. …”

    Investigating the role of basement structures in controlling facies characteristics, depositional models, and diagenetic alterations of the Sarvak Formation in the eastern and west... by Marzieh Mahmoodi, Hamzeh Mehrabi, Reza Nozaem

    Published 2024-06-01
    “…Depending on the presence or absence of palaeohighs (such as salt domes and horst structures), the number of these palaeoexposure surfaces and the intensity of the associated diagenetic alterations vary across different parts of the Zagros region.The four main stages of diagenetic evolution of the Khatiyah and Mishrif members of the Sarvak Formation are as follows:Stage 1: Marine transgression, sedimentation, and marine diagenesis of the Khatiyah Member in the early to mid-Cenomanian.Stage 2: Highstand of sea level, sedimentation, and marine diagenesis of the Mishrif Member in the mid- to late-Cenomanian.Stage 3: Relative sea level fall, emergence of the platform, exposure and meteoric diagenesis of the Mishrif Member at the Cenomanian-Turonian boundary.Stage 4: Deposition of shale facies in a lacustrine environment (Laffan Shale) during this stage.The diagenetic processes of the Sarvak Formation can be divided into two categories: 1) Diagenetic processes related to discontinuities, and 2) Diagenetic processes unrelated to discontinuities. …”
