An Overview of Solid Waste Management and Plastic Recycling in Qatar
(2012 , Article)
Municipal solid waste management (MSWM) constitutes one of the most crucial health and environmental problems facing authorities in the Arabian Gulf. Recent literature on current solid waste management (SWM) in Qatar has ...
CO 2 adsorption studies on Prussian blue analogues
(
Elsevier Inc.
, 2012 , Article)
Carbon dioxide (CO2) adsorption capacities of several Prussian blue (PB) analogues have been studied using the state-of-the-art Rubotherm® sorption apparatus to obtain adsorption and desorption isotherms of these compounds ...
High capacity carbon dioxide adsorption by inexpensive covalent organic polymers
(
Royal Society of Chemistry
, 2012 , Article)
Efficient CO2 scrubbing without a significant energy penalty remains an outstanding challenge for the fossil fuel-burning industry where aqueous amine solutions are still widely used. Porous materials have long been evaluated ...
Cloud-Ready Biometric System for Mobile Security Access
(
Springer
, 2012 , Conference Paper)
In this contribution, we introduce an application that allows a mobile phone to be used as a biometric-capture device for secure access to the cloud. In this application, the biometric capture and recognition are performed ...
A threshold-based opportunistic MAC protocol for MIMO wireless sensor networks
(
IEEE
, 2012 , Conference Paper)
In this paper, 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 ...
Modelling and compensation of frequency-dependent I/Q imbalance in multiple beamforming OFDM transceivers
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate the effects of asymmetric frequency-dependent joint transmit-receive I/Q imbalance on the performance of multiple beamforming MIMO OFDM systems. We derive the throughput-maximizing TX/RX ...
Digital baseband compensation of frequency-dependent joint TX/RX I/Q imbalance in beamforming MIMO OFDM transceivers
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate the effects of asymmetric frequency-dependent joint transmit-receive I/Q imbalance on the performance of beamforming MIMO-OFDM systems. We derive the throughput-maximizing transmit/receive ...
SINR analysis for beamforming OFDM systems under joint transmit-receive I/Q imbalance
(
IEEE
, 2012 , Conference Paper)
In this paper, we derive an analytical expression for the subcarrier average SINR of a beamforming OFDM system in the presence of joint transmit-receive I/Q imbalance. The derived expression quantifies the impact of the ...
LingoSnacks: M-Learning platform for language learning
(
IEEE
, 2012 , Conference Paper)
This paper reports the experience of designing and developing a multimedia m-Learning platform (named LingoSnacks) for interactive learning of Arabic spelling and vocabulary. It uses interactive game-like delivery methods ...
Applying and evaluating architectural patterns on a stock trading case study
(
IEEE
, 2012 , Conference Paper)
Teaching architectural and design patterns is a difficult task and not easy to understand by the students as patterns are expressed at a higher abstraction level than programming language constructs or graphical UML ...
