Downlink Interference Analysis of UAV-Based mmWave Fronthaul for Small Cell Networks
(
IEEE
, 2023 , Article)
In this paper, an unmanned aerial vehicles (UAV)-based heterogeneous network is studied to solve the problem of transferring massive traffic of distributed small cells to the core network. First, a detailed three-dimensional ...
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 ...
Space vector vs. sinusoidal carrier-based pulse width modulation for a seven-phase voltage source inverter
(
China Power Supply Society
, 2019 , Article)
The paper presents an extensive comparison between two pulse width modulation (PWM) control schemes, namely carrier-based and space vector based PWM for a seven-phase voltage source inverter. Sinusoidal carrier-based PWM ...
Bioelectrical Impedance Analysis Detects Body Fat Changes After Surgical Subcutaneous Fat Removal
(
Mary Ann Liebert
, 2024 , Article)
Background: The risk and metabolic effects of obesity are determined by the distribution of fat throughout the body. It has been proposed that the distribution of abdominal fat is more closely related to the metabolic risks ...
Non-Participatory Observation Of Integrated Management Of Childhood Illness Practices At Selected Basic Health Units Of District Abbottabad, Kp, Pakistan: A Qualitative Hermeneutic Study
(
Ayub Medical College
, 2023 , Article)
BACKGROUND: It was in 1995 when a strategy was devised to reduce under-five mortality in countries with a prevalence of child mortality above 40/1000 live births. This strategy is called "Integrated Management of Childhood ...
