Vibration attenuation control of ocean marine risers with axial-transverse couplings
The target of this paper is designing a boundary controller for vibration suppression of
marine risers with coupling mechanisms under environmental loads. Based on energy
approach and the equations of axial and transverse motions of the risers are…

Traffic sign detection optimization using color and shape segmentation as pre-processing system
One of performance indicators in an autonomous vehicle (AV) is its ability to accom-
modate rapid environment changing; and performance of traffic sign detection (TSD)
system is one of them. A low frame rate of TSD impacts to late decision making…

Predicting the notch band frequency of an ultra-wideband antenna using artificial neural networks
In this paper we propose to predict the notch frequency of an ultra-wideband
(UWB) antenna which operates in the frequency band from 3.85 GHz to 12.38
GHz. The prediction of the notch frequency in order to avoid interferences
between (WLAN)…

Performance of multi-hop cognitive MIMO relaying networks
with joint constraint of intercept probability and limited interference
In this paper, we propose a multi-hop multiple input multiple output (MIMO)
decode-and-forward relaying protocol in cognitive radio networks. In this
protocol, a multi-antenna secondary source attempts to send its data to a multi-
antenna…
