Capacity enhancement in cognitive radio wireless network with dynamic spectrum access
(
IEEE Computer Society
, 2014 , Conference Paper)
Deployment of femto-cells underlaying the macro-cell has been proven to greatly improve the system capacity and the indoor coverage. However, to successfully deploy this heterogeneous network, the interference among the ...
Cognitive relay-sharing by using hierarchical modulation under interference constraints
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate relay-sharing in cognitive radio (CR) networks to improve the secondary user's (SU's) performance in the presence of interference. It is assumed that the relay is shared simultaneously between ...
Analysis of heterogeneous cellular networks interference with biased cell association using Poisson cluster processes
(
IEEE Computer Society
, 2014 , Conference Paper)
Heterogeneous cellular networks (HetNets) achieve high data rates and coverage gains by distributing small cells over macro-cells based on random user demand. Recently, a novel approach to use stochastic geometry for ...
أخلاقيات استخدام الجمهور للشبكات الاجتماعية بعدثورات الربيع العربي وآثرها علي اتجاهاته نحو هذه الشبكات
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
كان من المفترض أن تقوم وسائل الإعلام - ومن بينها الشبكات الاجتماعية - باستكمال دورها في مرحلة إعادة البناء واستكمال مكتسبات واستحقاقات الثورات العربية من إقرار الدساتير واستكمال الأنظمة النيابية والتشريعية التي تساعد في ...
Assessment of Student Learning Outcomes for Assurance of Learning at Qatar University
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
From 2006 to 2012 Qatar University transitioned from doing no program level outcomes-based assessment of student learning to implementation of a robust, effective, and institutionally pervasive Student Learning Outcomes ...
Visualization of faces from surveillance videos via face hallucination
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Face hallucination can be a useful tool for visualizing a low quality face into a visually better quality, making it an attractive technology for many applications. While faces in surveillance videos are usually at very ...
An interactive annotation tool for indexing Historical manuscripts
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
When a huge collection of digitized old manuscripts are obtained as a part of their preservation, an appropriate indexing technique is essential to search through them. In this paper, we have proposed a novel tool to assist ...
Using codebooks generated from text skeletonization for forensic writer identification
(
IEEE Computer Society
, 2014 , Conference Paper)
In this paper, we propose a novel approach for writer identification using codebook generation based on text skeletonization.Unlike other schemes, the skeleton in this approach is segmented at its junction pixels into ...
On the use of time-frequency features for detecting and classifying epileptic seizure activities in non-stationary EEG signals
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper proposes new time-frequency features for detecting and classifying epileptic seizure activities in non-stationary EEG signals. These features are obtained by translating and combining the most relevant time-domain ...
Efficient segmentation of sub-words within handwritten arabic words
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Segmentation is considered as a core step for any recognition or classification method and for the text within any document to be effectively recognized it must be segmented accurately. In this paper a text and writer ...
