Vehicular traffic is endlessly increasing everywhere in the world and can cause terrible
traffic congestion at intersections. Most of the traffic lights today feature a fixed green light sequence,
therefore the green ...

The detection of ships at sea is a complex task made more so by adverse weather conditions, lack of night visibility, and large areas of concern. Synthetic aperture radar (SAR) imagery with large swaths can provide the ...
Oscillation-based testing (OBT) has been proven to be a simple, yet effective VLSI test for numerous circuit types. This paper investigates, for the first time, the application of OBT verification for second generation ...

In this paper, we consider two kinds of sampled-data observer design for a class of nonlin-
ear systems. The system output is sampled and transmitted under two kinds of truncations.
Firstly, we present de nitions of the ...

This paper describes the preliminary design and simulation towards a gigabit digital subscriber line modem that provides multi-user interference-free communication in a far-end crosstalk dominated environment by incorporating ...
In this paper, the leaderless consensus problem of multi-agent systems with
jointly connected topologies and nonlinear dynamics is considered, in which
the nonlinear dynamics are assumed to be non-identical and unknown. ...

A non-linear model-based control architecture for a single-stage grinding mill circuit closed with a hydrocyclone
is proposed. The control architecture aims to achieve independent control of circuit throughput
and product ...

This letter presents a dual band slot antenna with high gain for WLAN and WiMAX communication covering the IEEE802.11a/b and IEEE802.16d/e standards. The antenna consists of a microstrip fed slot with a complimentary stub ...
This study analyzes the economic system dynamics of investment in real estate from
mainly four participants in China. Local governments limit the supply of commercial and residential
land to raise fiscal revenue, and ...

The effect of the return from the platform
on which a cross-eye jammer is mounted is significant
in many practical cross-eye jamming scenarios. However,
all published analyses of skin-return affected cross-eye

Software defined networking (SDN) brings about innovation, simplicity in network management,
and configuration in network computing. Traditional networks often lack the flexibility to bring into
effect instant changes ...
Samuel, J.N.; Du Plessis, W.P. (Warren Paul)(South African Institute of Electrical Engineers, 2017-06)
This paper presents the application of specific emitter
identification (SEI) to access control and points out the security
caveats of current radio-based access remotes. Specifically,
SEI is applied to radio frequency ...
Generally, conventional controllers for comfort are designed by using on/off
control or proportional-integral (PI) control, with little consideration of energy
consumption of the system. This paper presents a ...

This paper presents the design and application of fractional single-input-single-output (SISO) controllers to
a grinding mill circuit, which is a multiple-input-multiple-output (MIMO) process. Two kinds of controllers
Van Zyl, Marianne; Hanekom, J.J. (Johannes Jurgens)(Acoustical Society of America, 2013-01)
The present study explored the acoustic characteristics of
prosodic cues that indicate a speaker’s reluctance when giving permission
or agreement using a single word (“okay”). Eight speakers (four
male, four female) ...

This paper presents an optimal energy management strategy for a grid-tied photovoltaic–wind-fuel cell
hybrid power supply system. The hybrid system meets the load demand consisting of an electrical load
and a heat pump ...
In this paper, we investigate joint design of quasi-cyclic low-density-parity-check (QC-LDPC)
codes for coded cooperation system with joint iterative decoding in the
destination. First, QC-LDPC codes based on the base ...
