Discrepancy in the Critical State Void Ratio of Poorly Graded Sand due to Shear Strain Localization
(
American Society of Civil Engineers (ASCE)
, 2020 , Article)
The critical state (CS) concept is a theoretical framework that models the constitutive behavior of soils, including sand and other granular materials. It supports the notion of a unique postfailure state, where the soil ...
Optimum Design of Plane Trusses Using Mathematical and Metaheuristic Algorithms on a Spreadsheet
(
Qatar University Press
, 2023 , Conference Paper)
Mathematical optimization refers to the process of finding the values of variables that maximize or minimize a function. Structural optimization is the process of designing a structure in such a way as to minimize its ...
Application of Metastructures for Targeted Low-Frequency Vibration Suppression in Plates
(
Springer
, 2022 , Article)
Purpose
We present an approach that combines finite element analysis and genetic algorithms to find the optimal configuration of local resonators created in the host structure to suppress their vibration in a target ...
Queue Discharge at Freeway On-Ramps Using Coordinated Operation of a Ramp Meter and an Upstream Traffic Signal
(
Elsevier
, 2020 , Conference Paper)
Ramp metering is an effective way of maintaining optimum traffic conditions and mitigating congestion on freeways. Several strategies for ramp metering exist in the literature. They are typically based on the freeway traffic ...
MXene (Ti3 C2 Tx )/Cellulose Acetate Mixed-Matrix Membrane Enhances Fouling Resistance and Rejection in the Crossflow Filtration Process
(
MDPI
, 2022 , Article)
Obstacles in the membrane-based separation field are mainly related to membrane fouling. This study involved the synthesis and utilization of covalently crosslinked MXene/cellulose acetate mixed matrix membranes with MXene ...
Poly (amido amine) dendrimer based membranes for wastewater treatment - A critical review
(
Elsevier
, 2023 , Article Review)
Membrane based wastewater treatment technologies in which polymeric membranes are most commonly used have been extensively applied in water/wastewater treatment to help address the issue of water shortage through ...
Organic fouling in forward osmosis: A comprehensive review
(
MDPI AG
, 2020 , Article Review)
Organic fouling in the forward osmosis process is complex and influenced by different parameters in the forward osmosis such as type of feed and draw solution, operating conditions, and type of membrane. In this article, ...
Durability characteristics of high and ultra-high performance concretes
(
Elsevier
, 2021 , Article)
Durability characteristics of high-performance concrete (HPC) and ultra-high performance concrete (UHPC) are evaluated in comparison to normal strength concrete (NSC). HPC and UHPC are cast using commonly available materials ...
Transit‐Oriented Development in Doha: The Case of the Al Sadd Neighborhood and Hamad Hospital Metro Station
(
MDPI
, 2021 , Article)
Over the last two decades, transit‐oriented development (TOD) has been widely implemented
as an integrated strategy to enhance urban livability. Doha, the capital of the State of Qatar,
has faced urban challenges such ...
Machine Learning-Based Respiration Rate and Blood Oxygen Saturation Estimation Using Photoplethysmogram Signals
(
MDPI
, 2023 , Article)
The continuous monitoring of respiratory rate (RR) and oxygen saturation (SpO2) is crucial for patients with cardiac, pulmonary, and surgical conditions. RR and SpO2 are used to assess the effectiveness of lung medications ...
