Impact of outdated CSI on the secrecy performance of dual-hop networks using cooperative jamming
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
This paper studies the problem of secure dual-hop AF network in the presence of eavesdropper. We study the secrecy performance of partial relay selection with outdated channel state information (CSI). We propose a system ...
Flexible thermo-electrochemical cells using Iodolyte HI-30 for conversion of low-grade heat to electrical energy
(
Royal Society of Chemistry
, 2016 , Article)
In this research work, we investigated the flexible thermo-electro chemical cells (TECs) for the conversion of low-grade heat into electrical energy in the temperature range of 20–70 °C. The TECs were fabricated using 30 ...
On the Effects of Temperature on the Performances of FSO Transmission under Qatar's Climate
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Strong atmospheric turbulence can highly affect the free space optical (FSO) link. In fact, the strength of turbulence is depending on weather factors where the temperature is considered as the main parameter increasing ...
Impact of moisture contents on the performance of organic bi-layer ITO/OD thermo-electric cells
(
Springer New York LLC
, 2016 , Article)
We propose a bi-layer thermo-electric cell based on elastic indium tin oxide (ITO) substrate and organic semiconductor orange dye (OD). It is observed that thermo-electric voltages are ~30% higher in bi-layer ITO/OD cell ...
Optimum sintering method and temperature for cold compact Bismuth Telluride pellets for thermoelectric applications
(
Qatar University Press
, 2021 , Poster)
This work intends to investigate the optimum sintering method and temperature that can improve the efficiency of bismuth telluride cold compact pellets for thermoelectric applications. Different p-type and n-type bismuth ...
Colloidal distribution of the PCPDTBT and VOPcPhO in the organic amalgam thin films and their optical properties
(
Springer Verlag
, 2017 , Article)
In this article, we investigated the optical properties and colloidal distribution of the PCPDTBT and VOPcPhO in the organic amalgam thin films prepared by spin-coating technique. A very even dispersion of donor and acceptor ...
Diversity-multiplexing tradeoff for log-normal fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Although there has been a growing interest on the study of diversity-multiplexing tradeoff (DMT), the existing works are mostly restricted to the outcomes reported for Rayleigh, Rician, and Nakagami fading channels. In ...
Feasibility and performance evaluation of a 6LoWPAN-enabled platform for ubiquitous healthcare monitoring
(
John Wiley and Sons Ltd
, 2016 , Article)
Technology has revolutionized medical practices by enabling more convenient and non-intrusive monitoring of patient's health, leading to next generation ubiquitous healthcare (u-healthcare). The exploitation of the Internet ...
Ultra-high aspect ratio copper nanowires as transparent conductive electrodes for dye sensitized solar cells
(
SPIE
, 2016 , Conference Paper)
We report the synthesis of ultra-high aspect ratio copper nanowires (CuNW) and fabrication of CuNW-based transparent conductive electrodes (TCE) with high optical transmittance (>80%) and excellent sheet resistance (Rs <30 ...
PEAM: A polymorphic, energy-aware MAC protocol for WBAN
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In remote healthcare monitoring and care delivery, obtaining the right information at the right time is critical. For these systems, designing an efficient MAC protocol that is able to meet the challenges on network quality ...
