THz vs. FSO: An Outage Probability and Channel Capacity Performance Comparison Study
(
IEEE
, 2023 , Conference Paper)
The main subject of this work is to make a detailed comparison between the performance of free-space optical (FSO) and terahertz (THz) links under different conditions. To this end, we first perform a detailed modeling of ...
UAV Trajectory Optimization for Directional THz Links Using Deep Reinforcement Learning
(
IEEE
, 2023 , Conference Paper)
As an alternative solution for quick disaster recovery of backhaul/fronthaul links, in this paper, a dynamic unmanned aerial vehicles (UAV)-assisted heterogeneous (HetNet) network equipped with directional terahertz (THz) ...
Pointing Error Modeling of mmWave to THz High-Directional Antenna Arrays
(
IEEE
, 2022 , Article)
This letter focuses on providing an analytical framework for the quantification and evaluation of the pointing error at high-frequency millimeter wave (mmWave) and terahertz (THz) communication links. For this aim, we first ...
Performance Analysis of Modulating Retroreflector Array for UAV-Based FSO Links
(
IEEE
, 2023 , Article)
In this work, we investigate the performance of free space optical (FSO) communication systems based on modulating retroreflector (MRR) array. In particular, we first characterize the MRR array-based FSO channel by taking ...
Channel Modeling and Performance Analysis of Directional THz Links Under Pointing Errors and α-μ Distribution
(
IEEE
, 2023 , Article)
This letter focuses on providing an analytical framework for the quantification and evaluation of high-directional terahertz communication links under pointing errors in terms of outage probability (OP), channel capacity, ...
Perspectives of healthcare workers on integrated management of childhood illness in Pakistan: A phenomenological approach
(
SAGE
, 2024 , Article)
In 2019, an estimated 5.2 million deaths were reported among children less than 5 years of age. At primary healthcare level, healthcare workers (HCWs) mostly rely on history and clinical findings and less on inadequate ...
The Affordances of Strategy Mapping
(
Academy of Management
, 2023 , Article)
Little research has focused on the role of strategy map and its affordances when developing a joint account of strategy in the context of a multidivisional organization. Building on the Strategy-As-Practice (SAP) research ...
Thousands of Qatari genomes inform human migration history and improve imputation of Arab haplotypes
(
Nature Research
, 2021 , Article)
Arab populations are largely understudied, notably their genetic structure and history. Here we present an in-depth analysis of 6,218 whole genomes from Qatar, revealing extensive diversity as well as genetic ancestries ...
A Switched-Capacitor Based Multilevel Inverter with Extendable Levels having Enhanced Voltage Gain for Renewable Energy Applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2023 , Conference Paper)
Various Switched-Capacitor based Multilevel Inverters (SCMLI) are suggested in literature. These converters can, however, provide fixed levels of ac output voltage. A higher number of renewable energy units must be linked ...
An Improved ANPC-based 7-level Inverter with Reduced Component and Low TSV for EV Applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2023 , Conference Paper)
The low dc-link voltage requirements of active-neutral-point-clamped (ANPC) inverters with voltage-gain capabilities make them attractive. The system's overall efficiency, reliability, and power density are improved by the ...
