A 3-D path-following controller is proposed in
this brief for a 6-degrees-of-freedom model-scaled autonomous
helicopter. The reference path and path-following errors are
newly defined using implicit expressions. On the ...

A 4.3 GHz voltage controlled oscillator (VCO)
with multiple independently tunable phase outputs is presented.
The VCO is realized by coupling two LC oscillators
together in order to obtain quadrature signals and is ...

This paper presents a six-bit current-steering digital-to-analogue converter (DAC), which
optimises the spurious free dynamic range (SFDR) performance of high-speed binary
weighted architectures by lowering current switch ...

(Society of Photo-optical Instrumentation Engineers, 2012)
Microdisplay technologies for near-to-eye applications mostly
use a complementary metal-oxide semiconductor (CMOS) processing
chip as backplane for pixel addressing, with extensive post-processing
on top of the CMOS ...

Congestion in dense traf c networks is a prominent obstacle towards realizing the performance
requirements of 5G new radio. Since traditional adaptive traf c signal control cannot resolve this type of
congestion, realizing ...

Mayhew-Ridgers, Gordon; Van Jaarsveld, Paul A.; Odendaal, J.W. (Johann Wilhelm); Joubert, Johan
(Institute of Electrical and Electronics Engineers, 2014)
The classic gain-transfer method assumes a uniform
plane wave incident over the apertures of the gain-transfer standard
(typically a standard-gain horn) as well as the antenna under
test. Variations in the incident field ...

Prinsloo, Jaco; Malekian, Reza
(MDPI Publishing, 2016-06-04)
Modern infrastructure, such as dense urban areas and underground tunnels, can effectively
block all GPS signals, which implies that effective position triangulation will not be achieved.
The main problem that is addressed ...
