High pressure CO2 absorption studies on imidazolium-based ionic liquids: Experimental and simulation approaches
(2013 , Article)
A combined experimental-computational study on the CO2 absorption on 1-butyl-3-methylimidazolium hexafluophosphate, 1-ethyl-3-methylimidazolium bis[trifluoromethylsulfonyl]imide, and 1-butyl-3-methylimidazolium ...
Highly stable nanoporous sulfur-bridged covalent organic polymers for carbon dioxide removal
(
John Wiley & Sons, Ltd
, 2013 , Article)
Carbon dioxide capture and separation requires robust solids that can stand harsh environments where a hot mixture of gases is often found. Herein, the first and comprehensive syntheses of porous sulfur-bridged covalent ...
Limitations and high pressure behavior of MOF-5 for CO2 capture
(
Royal Society of Chemistry
, 2013 , Article)
Porous network structures (e.g. metal–organic frameworks, MOFs) show considerable potential in dethroning monoethanol amine (MEA) from being the dominant scrubber for CO2 at the fossil-fuel-burning power generators. In ...
A combined computational and experimental study of high pressure and supercritical CO2 adsorption on Basolite MOFs
(
Elsevier Inc.
, 2013 , Article)
Metal organic frameworks (such as commercial Basolite®) display significant promise for CO2 capture and storage. Here, in order to monitor CO2 capture of Basolite®, we combined high pressure CO2 adsorption with high-pressure ...
Decentralized multiuser diversity with opportunistic packet transmission in MIMO wireless sensor networks
(
Elsevier
, 2013 , Article)
In this study, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas. We focus on single beam opportunistic communication and propose a threshold-based ...
I/Q imbalance in multiple beamforming {OFDM} transceivers: SINR analysis and digital baseband compensation
(
IEEE
, 2013 , Article)
In this paper, we start by investigating the impact of joint transmit-receive I/Q imbalance on the performance of direct-conversion beamforming OFDM transceivers. We derive a new analytical expression for the average ...
An integrated approach for airline flight selection and timing, fleet assignment, and aircraft routing
(
INFORMS Inst.for Operations Res.and the Management Sciences
, 2013 , Article)
Airline profits critically depend on the nature and efficiency of service they provide and accrue from a complex planning process involving schedule design fleet assignment aircraft routing and crew scheduling which are ...
MIP models for minimizing total tardiness in a two-machine flow shop
(
Palgrave Macmillan Ltd.
, 2013 , Article)
We propose compact mixed-integer programming models for the NP-hard problem of minimizing tardiness in a two-machine flow shop. Also, we propose valid inequalities that aim at tightening the models' representations. We ...
An assignment-based lower bound for a class of two-machine flow shop problems
(2013 , Article)
We present an assignment-based lower bound that is valid for a wide class of two-machine flow shop problems with a regular additive performance criterion. We provide empirical evidence that this new bound consistently ...
A model for enhancing robustness of aircraft and passenger connections
(
Elsevier
, 2013 , Article)
Airlines schedules are often subject to various uncontrollable factors that cause disruptions and delays. These delays not only constitute, for many passengers, the painful part of air travel, but also represent for airlines ...
