Maritime tracking using level sets with shape priors.
(2012)
Piracy is still a significant threat to ships in a maritime environment. Areas such as the coast of Somalia
and the Strait of Malacca are still plagued by pirates, and the total international cost of piracy numbers
in ...
Characteristics of rain at microwave and millimetric bands for terrestrial and satellite links attenuation in South Africa and surrounding islands.
(2010)
The emergence of a vast range of communication devices running on different types of technology has made convergence of technology become the order of the day. This revolution observed in communications technology has ...
Concatenated space-time codes in Rayleigh fading channels.
(2002)
The rapid growth of wireless subscribers and services as well as the increased use of internet
services, suggest that wireless internet access will increase rapidly over the next few years.
This will require the ...
Investigating the performance of generator protection relays using a real-time simulator.
(2013)
Real-time simulators have been utilized to perform hardware-in-loop testing of protection relays
and power system controllers for some years. However, hardware-in-loop testing of generator
protection relays has until ...
Investigating the dynamic performance of generator-pole-slip protection.
(2013)
Generators in an interconnected power system normally remain in synchronism with one another. However, severe faults that lead to loss of heavily loaded generators or large load blocks can cause oscillations in the generator ...
Video object segmentation and tracking.
(2005)
One of the more complex video processing problems currently vexing researchers is that of
object segmentation. This involves identifying semantically meaningful objects in a scene and
separating them from the background. ...
Frequency synchronization in multiuser OFDM-IDMA systems.
(2013)
Various multiuser schemes have been proposed to efficiently utilize the available bandwidth while ensuring an acceptable service delivery and flexibility. The multicarrier CDMA became an attractive solution to the major ...
Correlation of rain dropsize distribution with rain rate derived from disdrometers and rain gauge networks in Southern Africa.
(2011)
Natural phenomena such as rainfall are responsible for communication service disruption, leading
to severe outages and bandwidth inefficiency in both terrestrial and satellite systems, especially
above 10 GHz. Rainfall ...
A semi-empirical formulation for determination of rain attenuation on terrestrial radio links.
(2010)
Advances in today’s fast growing communication systems have resulted in congestion in the lower frequency bands and the need for higher capacity broadband services. This has made it inevitable for service providers to ...
Clear-air analytical and empirical K-Factor determination and characterization for terrestrial microwave LOS link applications.
(2013)
The transmission media, that is, the atmosphere, through which terrestrial and satellite signals traverse, is irregular. Thus, one requires proper knowledge on how variations in atmospheric refractive conditions will affect ...
