Outage analysis of selective cooperation in underlay cognitive networks with fixed gain relays and primary interference modeling
(
IEEE
, 2012 , Conference Paper)
Selective cooperation is a well investigated technique in non-cognitive networks for efficient spectrum utilization and performance improvement. However, it is still a nascent topic for underlay cognitive networks. Recently, ...
A novel P2P VoD streaming technique integrating localization and congestion awareness strategies
(2012 , Conference Paper)
The concept of the "future Internet" has evolved amongst researchers recently to relieve the tremendous pressure on the current Internet infrastructure to support the heterogeneous networking technologies, mobile devices, ...
Delay minimization through joint routing and resource allocation in cognitive radio-based mesh networks
(
IEEE
, 2012 , Conference Paper)
We consider wireless mesh networks in which the nodes are utilizing cognitive radios and try to opportunistically gain access to spectrum resources. In such networks, the timely delivery of the traffic is a challenging ...
Optimized Selective OFDMA in multihop network
(
IEEE
, 2012 , Conference Paper)
Selective OFDMA is a powerfull relaying technique with subcarrier based selection. This scheeme has a high potential to considerably improve the performance of cooperative OFDM systems. However, in practice, the implementation ...
إيران "الثوريّة" والثّورات العربيّة: ملاحظات بشأن السّياسة الخارجيّة الإيرانيّة ومآلاتها
(
المركز العربي للأبحاث ودراسة السياسات
, 2012 , Other)
عام وبضعة شهور تنقضي على ما تعارف عليه أهل السّياسة والإعلام وقبلهم من قاموا بالفعل نفسه "بالرّبيع العربي"[1]. وعلى الرّغم من أنّ المصطلح لم يكن في الأصل عربيًّا، لكنّه وجد له مكانةً في الذّهنيّة العربيّة، ربّما لما تحمله ...
Gene Expression Profiling of Embryonic Human Neural Stem Cells and Dopaminergic Neurons from Adult Human Substantia Nigra
(
Hamad bin Khalifa University Press (HBKU Press)
, 2012 , Conference Paper)
Neural stem cells (NSC) with self-renewal and multipotent properties serve as an ideal cell source for transplantation to treat neurodegenerative insults such as Parkinson's disease. We used Agilent's and Illumina Whole ...
Sustainability metrics for a supply chain: The case of small and medium enterprises
(
Inderscience Publishers
, 2012 , Article)
Using digraph and matrix method this research enunciates a simple method to quantify supply chain sustainability for small and medium enterprises. It proposes a numerical index which can be used to measure sustainability ...
NonLinear Control of Electrical Machines Using NonLinear Feedback

Channel Aware and Queue Aware Scheduling in LTE Uplink
(
SpringerLink
, 2012 , Conference Paper)
Long Term Evolution (LTE) uses single carrier frequency division multiple access (SCFDMA) technique as the multiple access scheme in the uplink, due to its low peak to average power ratio (PAPR) compared to orthogonal ...
Maximizing secondary-user satisfaction in large-scale DSA systems through distributed team cooperation
(2012 , Article)
We develop resource and service management techniques to support secondary users (\su s) with QoS requirements in large-scale distributed dynamic spectrum access (\osa) systems. The proposed techniques empower \su s to ...
