Review on organic solar cells
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
The serious threat of global warming on earth made it necessary to look for alternative sources of energy. In fact, the seek for clean and cheap energy is subject of several research investigations nowadays, and the invention ...
On the effects of combined atmospheric fading and misalignment on the hybrid FSO/RF transmission
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Free-space optical (FSO) communication is known for its various impairments such as atmospheric turbulence and misalignment fading. In this paper, we study the performance of an FSO link operating under combined path loss ...

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, ...
