Modeling and sensitivity analysis of the forward osmosis process to predict membrane flux using a novel combination of neural network and response surface methodology techniques
(
MDPI AG
, 2021 , Article)
The forward osmosis (FO) process is an emerging technology that has been considered as an alternative to desalination due to its low energy consumption and less severe reversible fouling. Artificial neural networks (ANNs) ...
Investigation of the effect of surfactant on the electrokinetic treatment of PFOA contaminated soil
(
Elsevier
, 2022 , Article)
Perfluorooctanoic acid (PFOA) is a persistent, nonbiodegradable environmental pollutant progressively becoming more problematic. Due to its ubiquitous use, PFOA is one of the PFAS chemicals frequently detected in the ...
A novel electrocoagulation electrode configuration for the removal of total organic carbon from primary treated municipal wastewater
(
Springer
, 2020 , Article)
In this paper, the removal of total organic carbon (TOC) from a primary treated municipal wastewater using a new electrode configuration in electrocoagulation was evaluated. The used electrode configuration induces a ...
Numerical study on the damping characteristics of a shock absorber valve utilizing different velocities through CFD analysis
(
National Technical University of Athens
, 2021 , Conference Paper)
Shock absorbers or hydraulic dampers are power dissipating devices. The fluid flow inside the damper is governed by predefined passages. The damping effect is accomplished by the resistance of oil to flow through the ...
Energy harvesting from railway vibrations - A numerical study based on beam-on-elastic-foundation under quasi-static loading
(
National Technical University of Athens
, 2021 , Conference Paper)
The objective of this paper is to investigate energy harvesting of train-induced rail
vibrations and to provide a comparison between various feasible harvesting locations based on
the expected electrical power output. ...
LiDAR based hydro-conditioned hydrological modeling for enhancing precise conservation practice placement in agricultural watersheds
(
Springer Science and Business Media B.V.
, 2022 , Article)
High resolution Light Detection and Ranging (LiDAR)-derived Digital Elevation Models (DEMs) improve hydrologic modeling and aid in identifying the targeted locations of best conservation practices (CPs) in agricultural ...
Bioinspired modeling and biogeography-based optimization of electrocoagulation parameters for enhanced heavy metal removal
(
Elsevier
, 2022 , Article)
Electrocoagulation is an effective wastewater treatment process for the removal of heavy metals. This study focuses on deriving optimal conditions for removing heavy metals, viz. Lead (Pb), Cobalt (Co), and Manganese (Mn) ...
3D synchrotron computed tomography study on the influence of fines on gas driven fractures in Sandy Sediments
(
Elsevier
, 2020 , Article)
Production of methane from hydrate-bearing sediments requires hydrate dissociation for releasing
mobile methane gas in sediments prior to gas production operations. Fines may migrate through or
clog the pore space of ...
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 ...
Fines effect on gas flow in sandy sediments using μCT and pore networks
(
Elsevier
, 2022 , Article)
Gas production from hydrate-bearing sediments requires methane dissociation, which induces two-phase gas flow, mobilizing fine clay particles from within saturated pores. Fines migration within sandy sediments results in ...
