Study of the effects of dust, relative humidity, and temperature on solar PV performance in Doha: Comparison between monocrystalline and amorphous PVS
(
Taylor & Francis
, 2013 , Article)
The sensitivity of various solar photovoltaic technologies to dust, temperature, and relative humidity is investigated for Doha's environment. Results obtained show that monocrystalline photovoltaics (PVs) have efficiencies ...
Automatic number plate recognition system on an ARM-DSP and FPGA heterogeneous SoC platforms
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
The ARM-DSP based ANPR system described is designed for commercial applications where the need for low power, low prices and real time systems is vital. A single FPGA can also be added as a plug-in to the ARM-DSP based ...
A solid-phase extractant based on microemulsion modified date pits for toxic pollutants
(
Elsevier
, 2013 , Article)
Application of microemulsion modified raw date pits as an inexpensive solid extractant for removing methylene blue (MB), copper ion (Cu2+) and cadmium ion (Cd2+) has been presented. The results summarised herein are also ...
A hybrid spectrum sensing technique with multiple antenna based on GLRT
(2013 , Conference Paper)
Spectrum sensing is the core for any cognitive radio network. Quick detection of the primary user signal allows for higher spectrum efficiency. In this paper, we introduce and implement a new hybrid spectrum sensing technique ...
Adaptive modulation in multi-user cognitive radio networks over fading channels
(
IEEE Computer Society
, 2013 , Conference Paper)
In this paper, the performance of adaptive modulation in multi-user cognitive radio networks over fading channels is analyzed. Multi-user diversity is considered for opportunistic user selection among multiple secondary ...
Bromate reduction by ultraviolet light irradiation using medium pressure lamp
(
Taylor & Francis
, 2013 , Article)
Bromate reduction in water by ultraviolet irradiation using medium-pressure lamps (UV-M) emitting light in the range of 200-600 nm has been investigated. Effects of certain experimental parameters including the initial ...

(
American Institute of Physics
, 2013 , Article)
Incorporation of molecules into porous silicon (PS) matrix is of particular interest for potential utilization in hybrid organic-semiconductor devices. In this study, the incorporation of Congo Red molecules inside luminescent ...
Towards u-health: An indoor 6LoWPAN based platform for real-time healthcare monitoring
(
IEEE
, 2013 , Conference Paper)
Ubiquitous healthcare is the key to handle the challenges of the growing population around the world. A variety of u-healthcare systems have been developed using various short-range technologies and proprietary protocols ...
Deadbeat control of Z source inverter with voltage ride-through capability
(
IEEE
, 2013 , Conference Paper)
This paper presents a Z source inverter connected to grid. The effect of voltage sags on ZSI will be studied when two different ac side control schemes are used. The paper compares the performance of both PI control and ...
Packet relaying control in sensing-based spectrum sharing systems
(2013 , Conference Paper)
Cognitive relaying has been introduced for opportunistic spectrum access systems by which a secondary node forwards primary packets whenever the primary link faces an outage condition. For spectrum sharing systems, cognitive ...
