(Amer Assoc Cancer Research,, 2019)[Abstract Not Available] -
A non-communicating multi-robot system with switchable formations
(2013)We consider connected navigation of autonomous mobile robots with transitions in the group formation. The robots navigate using simple local steering rules without requiring explicit communication among themselves. The ... -
Noncoherent Ultra Wideband Wireless Sensor Networks for Primary User Detection
(IEEE Computer Society, 2016)As a result of increasing demand for new technologies unlicensed usage of available spectrum has become very essential to provide an efficient usage of spectrum. For that reason sensor networks may be a reliable option to ... -
A Novel Approach for Voltage Control in Electrical Power Distribution Systems
(IEEE, 2018)This paper proposes a novel approach for voltage control in 3-phase unbalanced distribution systems. The approach is based on the change of the magnetizing reactances of the voltage regulators in the system. We used an ... -
Novel Channel Models For Visible Light Communications
(Spie-Int Soc Optical Engineering, 2015)In this paper we investigate channel modeling for visible light communications (VLC) using non-sequential ray tracing simulation tools. We create three dimensional realistic simulation environments to depict indoor scenarios ... -
A Novel Image Steganography Technique based on Similarity of Bits Pairs
(IEEE, 2017)Steganography is one of the most important information hiding mechanism which can be used along with cryptography for providing adequate data security. The common Steganographic mediums used are text image audio and video ... -
A Novel Indoor Channel Model for TVWS Communications based on Measurements
(IEEE, 2018)In this paper we present an indoor measurement campaign for TV white space bands inside a university building. The measurement results are compared with different indoor propagation models in the literature. We observed ... -
A Novel Transmit Array Structure for Optical Spatial Modulation
(IEEE, 2019)The performance of multiple input single output (MISO) and multiple input multiple output (MIMO) systems is limited by spatial channel correlation. This limitation becomes particularly severe in light lidelity (LiFi) ... -
A numerical method for frequency determination in the astable cellular neural networks with opposite-sign templates
(IEEE, 2006)In this study a numerical method is proposed to determine the oscillation frequencies in the astable cellular neural networks with opposite-sign templates [1]. This method depends on the training of a multilayer perceptron ... -
A Numerical Study of Shallow Mixing Development over Flat Surface and Dunes
(TSINGHUA UNIV, 2013)Results of a high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel with a smooth flat bed and dunes. ... -
OFDM with transmit and receive antenna selection based on subcarrier groups
(IEEE, 2012)In this paper the performance of coded OFDM transmission over multiple antennas is explored when joint transmit and receive antenna selection is employed. The channel is assumed as Rayleigh frequency selective fading channel ... -
On Channel Estimation in DC Biased Optical OFDM Systems Over VLC Channels
(IEEE Computer Society, 2016)Visible Light Communication(VLC) has been considered as a potential access option for 5G wireless systems to solve performance limitation due to bandwidth shortage at radio frequency (RF) band. In (VLC) system illumination ... -
On preserving connectivity of autonomous mobile robots
(IEEE, 2009)The connectivity of the autonomous mobile robots is considered in this paper. The group navigation is provided using simple local steering rules and without any explicit communication. Sub-optimal solutions are invoked to ... -
On sectional curvatures of a Weyl manifold
(2006)In this paper it is proved that if at each point of a Weyl manifold the sectional curvature is independent of the plane chosen then the Weyl manifold is locally conformal to an Einstein manifold and that the scalar curvature ... -
On the selection of ınterpolation points for rational Krylov Methods
(Springer-Verlag Berlin, 2012)We suggest a simple and an efficient way of selecting a suitable set of interpolation points for the well-known rational Krylov based model order reduction techniques. To do this some sampling points from the frequency ... -
