First Hybrid 1gbps/0.1 Gbps Free-space Optical /rf System Deployment And Testing In The State Of Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
I.BACKGROUND & OBJECTIVES Owing to its high-bandwidth, robustness to EMI, and operation in unregulated spectrum, free-space optical communication (FSO) is uniquely qualified as a promising alternative or complementary ...
Determining the Outdoor Air Ventilation with Carbon Dioxide (CO2) as a Tracer Gas
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Insufficient ventilation can lead to occupant complaints of discomfort and reduced productivity as human and building generated pollutants build up. Some combinations of these elevated pollutants may have short or long-term ...
Calibration & Temperature Controlled Setup for Air Quality Sensors
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Indoor air pollution is a major issue affecting public health. Due to hot climate, humidity and lack of natural green spaces, life is mostly confined indoors in many countries of the MENA region. Vulnerable population, ...
Integration of the inexpensive CuNWs based transparent counter electrode with dye sensitized photo sensors
(
Royal Society of Chemistry
, 2016 , Article)
We demonstrate, a newly developed, inexpensive transparent conducting electrode (TCE) based on copper nanowires (CuNWs) combined with reduced graphene oxide (rGO) and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate ...
Structural, morphological and optical properties of PEDOT:PSS/QDs nano-composite films prepared by spin-casting
(
Elsevier B.V.
, 2016 , Article)
This paper describes the structural, morphological and optical properties of the nano-composite of poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and quantum dots (QDs). The ZnSe and CdSe QDs have been ...
Dielectric properties of Mn doped Bismuth Barium Titanate based ceramic thin films prepared by PLD technique
(
Elsevier Ltd
, 2017 , Article)
In this article, the effect of Mn doping on the permittivity and dielectric loss in 0.67BiFeO3-0.33BaTiO3 (BF-BT) based film bulk acoustic resonator test structures has been investigated. BF-BT thin films were deposited ...
