New 2-Edge-Balanced Graphs from Bipartite Graphs
(Wiley-Blackwell, 2016)
Let G be a graph of order n satisfying that there exists lambda epsilon Z(+) for which every graph of order n and size t is contained in exactly. distinct subgraphs of the complete graph K-n isomorphic to G. Then G is ...
Threshold-based Steganography: A Novel Technique for Improved Payload and SNR
(Zarka Private Univ, 2016)
Steganography is the art of hiding user information in various file types including image audio and video. Security of steganography lies in imperceptibility of secret information in the cover image. Human Visual System ...
Optical and structural properties of Ta2O5-CeO2 thin films
(Elsevier Science Bv, 2007)
In this study the sol-gel spin-coating method has been used to make Ta2O5-CeO2 thin films. These films have been prepared in various composition ratios to observe changes in their optical and structural properties. Reflectance ...
Slow release of trapped homopolymers from a swelling polymeric gel: A fluorescence study
(Taylor & Francis Inc, 2008)
In-situ steady-state fluorescence experiments were performed for studying slow release of pyrene-labeled polystyrene chains from polystyrene gels formed by free-radical crosslinking copolymerization. Atom transfer radical ...
Influence of pH on the optical and structural properties of spin coated CeO2-TiO2 thin films prepared by sol-gel process
(Elsevier Science Bv, 2007)
Optical and structural properties of mixed CeO2-TiO2 thin films have been investigated by varying the pH of the coating sol. The films were prepared by sol-gel process using spin-coating technique with a spin speed of 2500 ...
Distributed estimation with channel estimation error over orthogonal fading channels
(IEEE, 2007)
We study distributed estimation of a source corrupted by an additive Gaussian noise and observed by sensors which are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. The fading ...
A low-complexity time-domain MMSE channel estimator for space-time/frequency block-coded OFDM systems
(Hindawi Publishing Corporation, 2006)
Focusing on transmit diversity orthogonal frequency-division multiplexing (OFDM) transmission through frequency-selective channels this paper pursues a channel estimation approach in time domain for both space-frequency ...
Linear expansions for frequency selective channels in OFDM
(Elsevier GMBH Urban & Fischer Verlag, 2006)
Modeling the frequency selective fading channels as random processes we employ a linear expansion based on the Karhumen-Loeve (KL) series representation involving a complete set of orthogonal deterministic vectors with a ...
Nearest Fixed Clustering Algorithm (NFCA) for Wireless Sensor Networks
(Institute of Electrical and Electronics Engineers Inc., 2016)
The objective of reducing energy consumption at the sensor nodes has become a key research area for wireless sensor networks (WSNs) in recent years. With the steady increase in the cost of energy the existing algorithms ...
A location-based movie advisor application for android devices
(Springer Verlag, 2015)
Android is one of the world’s most popular mobile platforms. There are more than 600000 applications available today’s market place. Movie advisor applications are also available in Google Play but there is no location-based ...
