A passive DSP approach to fetal movement detection for monitoring fetal health
(2012 , Conference Paper)
Fetal movement can help clinicians understand fetal functional development. Active methods for fetal monitoring such as ultrasound are expensive and there are objections to their long term usage. This paper presents a ...
Performance analysis of selective cooperation with fixed gain relays in Nakagami-m channels
(
elsevier B.V.
, 2012 , Article)
Selecting the best relay using the maximum signal to noise ratio (SNR) among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay ...
Joint hierarchical modulation and network coding for two way relay networks
(
IEEE
, 2012 , Conference Paper)
The performance of a joint Hierarchical Modulation (HM) and Network Coding (NC) scheme for two way relay networks is introduced and evaluated in this paper. The proposed scheme uses selective relaying based on a signal-to-noise ...
An HIV-STI risk reduction program among undergraduate students at a northern Nigerian university: A randomized controlled field trial
(2012 , Article)
Aim
This study aims to evaluate the effectiveness of a peer-led human immunodeficiency virus-sexually transmitted infections (HIV-STI) intervention program based on the Information-Motivation-Behavioral Skills model among ...
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 ...
