Eco-efficiency performance of airlines in eastern Asia: A principal component analysis based sustainability assessment
(
IEOM Society
, 2021 , Conference Paper)
Bringing sustainability practices to the aviation industry has helped in offsetting carbon emissions to a great extend. However, the question of whether these practices neutralize carbon emissions is yet unanswered. The ...
Ridge Penalization-based weighting approach for Eco-Efficiency assessment: The case in the food industry in the United States
(
IOP Publishing Ltd
, 2020 , Conference Paper)
Eco-efficiency assessment is of great importance for monitoring and managing environmental and economic aspects of sustainable development. The eco-efficiency indicators are required to assess and measure the impact of ...
An integrated sustainable quality management framework for quality-related research
(
IEOM Society
, 2021 , Conference Paper)
The existence of synergies between several quality management systems and sustainability has spurred great interest in better understanding the sustainable quality management (SQM) concept over the past decade. This paper ...
Optimizing university campus shuttle bus congestion focusing on system effectiveness and reliability: A combined modeling based-routing approach
(
IEOM Society
, 2021 , Conference Paper)
Increased vehicular queuing inside universities has amounted to pressing concerns for staff and students, distorting their time schedules to reach classes and office buildings on time. This paper attempts to alter the ...
A mechanistic gas kick model to simulate gas in a riser with water and synthetic-based drilling fluid
(
Society of Petroleum Engineers
, 2020 , Conference Paper)
This paper presents a simple mechanistic model to describe a gas kick in a drilling riser with water- based mud (WBM) and synthetic-based mud (SBM). This model can estimate key kick parameters such as the change in the ...
Treatment of saline wastewater and carbon dioxide capture using electrodialysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
In this study, electrodialysis was used to achieve a combined action of capturing carbon dioxide and treating high-salinity water to produce hydrochloric acid, hydrogen gas, and carbonate and bicarbonate salts. Sodium ...
CO2 Absorption Capacity and its Enthalpy of Absorption in Aqueous Blend of MDEA/Piperazine/Arginine
(
Institute of Physics Publishing
, 2020 , Conference Paper)
In this work, the solubility data of CO2 in aqueous blends of N-Methyldiethanolamine, Piperazine and Arginine (MDEA/PZ/ARG) of a total concentration of two moles is presented. CO2partial pressure was varied from 9 to 99 ...
Investigation of gas-liquid flow using electrical resistance tomography and wavelet analysis techniques for early kick detection
(
American Society of Mechanical Engineers (ASME)
, 2021 , Conference Paper)
Gas kick is a well control problem and is defined as the sudden influx of formation gas into the wellbore. This sudden influx, if not controlled, may lead to a blowout problem. An accidental spark during a blowout can lead ...
A CFD Investigation on the Effect of IPSBR Operational Conditions on Liquid Phase Hydrodynamics
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
This study used a computational fluid dynamics simulation of an inert-particle spouted-bed reactor, which consists of a cylindrical vessel with a conical base, to investigate the effect of different operational parameters ...
Synthesis and Characterization of Fe3O4 Nanoparticles Using Different Experimental Methods
(
Institute of Physics Publishing
, 2020 , Conference Paper)
This paper reports a comparative study on the synthesis of Fe3O4 nanoparticles using three different methods, namely; Co-precipitation, Sonochemical and Solvothermal methods. Ferric chloride hexahydrate (FeCl3.6H2O) and ...
