Laboratory testing of full-scale pipes partially embedded in soil to study soil-pipe interaction of offshore seabed oil and gas pipelines - Initial observations
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
The geotechnical aspect of the design of off-shore oil and gas pipelines is a challenge due to inherent uncertainties in predicting soil-pipe interaction behaviour. Physical modeling is often sought after to gain insight ...
Geotechnical considerations on the design of piled rafts on rock
(
Research Publishing Services
, 2011 , Conference Paper)
This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ...
Microstructural investigation of gamma-irradiated ultra high molecular weight polyethylene in nitrogen atmosphere
(
Trans Tech Publications
, 2010 , Conference Paper)
In this paper the results of structural changes in ultra high molecular polyethylene (UHMWPE) upon gamma irradiation and storage in nitrogen environment are reported. Based on differential scanning calorimetry (DSC), wide ...
Effect of gamma irradiation on the microstructure and morphology of polyethylene oxide and polyvinyl alcohol blends
(
Trans Tech Publications
, 2010 , Conference Paper)
Thin films of a blend of 90, 75, 50 (wt/wt%) percentage of polyethylene oxide and polyvinyl alcohol were synthesized and irradiated with 5, 25, 50, 100 and 200 kGy. The presence of PVA leads to diffusion controlled mechanism ...
Performance analysis of M2M communication networks for QoS-differentiated smart grid applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
We study the performance of Machine-to-Machine (M2M) communications in Long Term Evolution Advanced (LTE-A) networks. The proposed analysis is applied to the random access procedure within LTE-A for the calculation of the ...
Joint uplink-downlink carrier aggregation scheme in LTE-A
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Long Term Evolution Advanced (LTE-A) supports a wide range of applications that continuously demand for more resources in order to satisfy the customers' needs. Starting from release 10, Carrier Aggregation (CA) technology ...
Adaptive Cooperative Network Coding based MAC protocol for device-to-device communication
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Device-to-Device (D2D) communication allows the direct connection of mobile devices in a cellular network. In D2D networking, cooperative communication is inherent due to the proximity of the devices that are able to ...
Genetic diversity of date palm genotypes in qatar as determined by SSR and ISSR markers
(
International Society for Horticultural Science
, 2010 , Conference Paper)
Date palm is the most important fruit tree in Qatar. Recently developed techniques, based on DNA markers, offer new tools for genetic analysis. The objectives of the present study are to analyze the genetic diversity among ...
