Research on orthogonal multi-carrier underwater acoustic communication system based on fractional Fourier transform by Yi-lin WANG, Yun CHEN, Jing-wei YIN, Ping CAI, Yi-meng ZHANG

“…Aimed at the traditional OFDM communication system fails when the channel was frequency-selective,rapidly fading and had the Doppler effects,resulting in inter-carrier interference,a orthogonal multi-carrier system for underwater acoustic communication was proposed,which employed orthogonal signal basis of the chirp type corresponding to the fractional Fourier transform (FRFT) signal basis.The scheme used the orthogonal LFM signal as sub-carrier to modulate,which had same chirp rate but different center frequency with overlapped bandwidth,and used fractional Fourier transform for modulation and demodulation method to transmit information.For suppression of the multi-paths channel effect,the guard interval (GI) was used between signal data frame.And the position correction in fractional domain method combining with QDPSK was proposed to suppress the Doppler effects,which simplified the system complexity.The communication scheme had the characteristic of high communication rate,and the maximum rate was up to 3 600bit/s.The effectiveness and reliability of this system was verified through a large number of simulation and lake experiments.…”

Data forwarding incentive mechanism based on auction model in mobile social network by Hao LIU, Zhi-gang CHEN, Lian-ming ZHANG

“…Abstract:A data forwarding incentive mechanism based on auction model in mobile social network was proposed.In this incentive mechanism,the first-price sealed auction mode was extended,the transaction mode of virtual currency payment was adopted,and the procedure of data forwarding between nodes was abstracted into the auction transaction model.Based on the node's resource state,the virtual currency and the data property,the evaluation function of data forwarding transaction was given,and then the node gives the corresponding price according to the evaluation function and game strategy.Through the game analysis,the Nash equilibrium solution of AMIM was found,and the lowest bidder,of which the bid price was lower than the evaluation of data forwarding request node would been selected as the service provider for this data forwarding.In this incentive mechanism,the rational mobile nodes were enforced to voluntarily participate in data forwarding cooperation to maximize their own interests.The simulation experiment shows that AMIM mechanism can effectively reduce the energy consumption and improve the success rate and efficiency of data forwarding in the whole network system.…”

Gross motor abnormalities in relation to balance and weight indicators in children with spastic diplegia by Lamis Neyazy Elrakhawy, Khaled Ahmed Mamdouh, Hoda Abdel Azim Eltalawy, Radwa S. Abdulrahman

“…Dynamic balance was evaluated by the overall stability index (OSI) in the Biodex Balance System and gross motor capacities (GMC) were evaluated by standing and walking dimensions in GMFM. Results On comparing outcome variables, there were significant differences among groups in BMI, GMC, and OSI (P < 0.001). …”

Free Vibrations with Large Amplitude of Axially Loaded Beams on an Elastic Foundation Using the Adomian Modified Decomposition Method by Desmond Adair, Askar Ibrayev, Alima Tazabekova, Jong R. Kim

“…Analytical solutions describing free transverse vibrations with large amplitude of axially loaded Euler–Bernoulli beams for various end restrains resting on a Winkler one-parameter foundation are obtained using the Adomian modified decomposition method (AMDM). The AMDM allows the governing equation to become a recursive algebraic equation, and, after some additional simple mathematical operations, the equations can be cast as an eigenvector problem whose solution results in the calculation of natural frequencies and corresponding closed-form series solution of the mode shapes. …”
