Computer aided diagnosis system based on machine learning techniques for lung cancer
(2012 , Conference Paper)
Cancer is a leading cause of death worldwide. Lung cancer is a type of cancer that is considered as one of the most leading causes of death globally. In Malaysia, it is the 3rd common cancer type and the 2nd type of cancer ...
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 ...
Security oriented service composition: A framework
(
IEEE
, 2012 , Conference Paper)
This paper argues that in order to address the challenges of security compatibility checking between the client's software and the service software in a service oriented software environment, the followings have to be ...
EasyCapstone: A framework for managing and assessing capstone design projects
(
IEEE
, 2012 , Conference Paper)
To enhance students learning and satisfy ABET requirements, the Department of Computer Science and Engineering at Qatar University undertook over the past few years significant enhancements to the senior design project ...
