Exact solution of space-Time Fractional Coupled EW and Coupled MEW Equations Using Modified Kudryashov Method

引用

Communications in Theoretical Physics 2017年第7期67卷 49-56页

作者： K. R. Raslan Talaat s. el-Danaf Khalid K. Ali Mathematics Department Faculty of Science Al-Azhar University Mathematics Department Faculty of science Ai-Azhar University Nasr City 11884 Cairo Egypt Faculty of Science Menoufia University Shebein E1-Koom Egypt

In the present paper, we established a traveling wave solution by using modified Kudryashov method for the space-time fractional nonlinear partial differential equations. The method is used to obtain the exact solutions for different types of the space-time fractional nonlinear partial differential equations such as, the space-time fractional coupled equal width wave equation(CEWE) and the space-time fractional coupled modified equal width wave equation(CMEW), which are the important soliton equations. Both equations are reduced to ordinary differential equations by the use of fractional complex transform and properties of modified Riemann–Liouville derivative. We plot the exact solutions for these equations at different time levels.

Objective: To clarify the antioxidant effect of butylated hydroxytoulene (BHT) at different concentrations on cooled and post frozen semen diluted in tris-citrate-fructose egg yolk glycerol and lecithin -based extenders. Methods: Forty ejaculates were harvested from four buffalo bulls by means of the artificial vagina. Ejaculated semen samples were diluted with each of the tris citrate-fructose egg yolk glycerol and lecithin-based extender diluents. The semen samples diluted with each of the two extenders were added to pre-warmed dried test tubes containing BHT (prepared in ethanol) to get concentrations at 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 mM/mL BHT. These ingredients were put at 37 ℃ for 5 min to allow the proper BHT spermatozoal permeation. The diluted semen samples were cooled to 5 ℃ and then frozen to -196 ℃ in 0.25 mL ministraws before dipping in liquid nitrogen pending its evaluation. sperm motility, viability, morphology, intact acrosome and membrane integrity were tested. Visual motility was tested using a high power ordinary microscope (at 400 × ) with closed circuit television, and sperm concentration was tested using Neubauer haemocytometer and abnormality % using eosin-nigrosin stain. spermatozoal membrane integrity was tested using the hypo-osmotic s.elling test. The sperm with swollen twisting tail was normally intact. sperm acrosomal integrity % was tested as mentioned by Watson. Results: Addition of BHT improved (Pssive motility, viability, morphology and acrosome as well as plasma membrane integrities at 0.5-2.0 mM/mL depending upon types of used extenders and stages of pre-and post-freezing process. Higher levels of 2.5 and 3.0 mM/mL BHT had a deteriorating (Psult if compared to the control and all extenders assayed. Conclusions: BHT addition at lower concentration can improve pre-frozen and post-thawed buffalo sperm quality.

Journal of Materials science & Technology 1998年第4期14卷 361-367页

作者： el-Anwar, I.M. el-Henawii, s.A. National Research Center Dokki Cairo Egypt Faculty of science Helwan University Egypt

Fatty acid esters have been prepared by reacting the acid C//1//8 with polyethylene glycols having varying numbers of oxyethylene units (4-88 units) by the direct esterification reaction method. surface and interfacial tensions were studied at various experimental conditions, including, concentration, temperature and chemical constitution of the surfactant. Critical micelle concentrations (CMC), surface excess and residual area occupied by each surface active agent molecule A have been calculated by using Gibb's equations. CMC values range from 10 to 55 multiplied by 10** minus **5 mole/L for all studied agents, while the residual area occupied by each molecule varies from 0.6 to 1.5 nm**2. Variation of CMC of some of these agents with temperature have been also examined and the obtained data were used to calculate the heat of micellization delta H//m and the entropy change during micellization delta s//m. Values of delta H//m vary from 14.63 kJ/mole to 2.717 kJ/mole depending on the chemical constitution of the agent under consideration. The apparent dipole moments mu of three surfactant were measured following the Headstrand's method. (Edited author abstract) 23 Refs.

Performance of OFDM system with Constant Amplitude Modulation

引用

Circuits and systems 2013年第4期4卷 329-341页

作者： Waleed saad Nawal el-Fishawy sayed el-rabaie Mona shokair Department of electronic and Communication Engineering Faculty of Electronic Engineering Minoufiya University Menouf Egypt

The Orthogonal Frequency Division Multiplexing (OFDM) technique has recently received considerable attention for wireless networks. Despite its advantages, it has a major drawback of its high Peak-to-Average Power Ratio (PAPR) value which affects the system efficiency and the cost. In this paper, a proposed system is discussed to achieve 0 dB PAPR value. It depends on a proposed block, called Constant Amplitude (CA) modulation. The whole characteristic mathematical analysis is presented for the proposed system. Additionally, the complexity evolution is explained. Afterwards, many MATLAB simulation programs are executed. Time and frequency domain behaviors are presented. Furthermore, in-band distortion introduced by the proposed CA modulation is calculated in terms of Error Vector Magnitude (EVM). Moreover, the proposed system outperforms the conventional one when compared in terms of PAPR, equalization, and BER under Additive White Gaussian Noise (AWGN) channel and multipath fading channels. In addition, the impact of the proposed scheme design parameter is studied.
