Journal of Rare earths 2013年第7期31卷 715-721页

Complexes of La （III）, Nd（III）, Gd（III）, Sm（III）, and Ce（IV） were synthesized with Schiff base [（3,5-di-tert-butyl-2-hy- droxybenzyl） amino] acetic acid （H3L）. The ligand and its complexes were synthesized and characterized based on the following analysis： elemental analyses, FAB-mass, molar conductance measurements, magnetic measurement, UV-visible, IR, and NMR spectral studies. The spectral data revealed that the ligand acted as a neutral tridentate coordinating to metal ion through ONO donor sequence. Thermal degradation studies of the ligand and its complexes showed that the previous lanthanide complexes were more thermally stable than the ligand itself. The Schiff base and its complexes were screened for their antibacterial （escherichia coli, Staphylococcus aureus） and antifungal （Aspergillus flavus and Candida Albicans）.

A Squared-Chebyshev wavelet thresholding based 1D signal compression

引用

Defence Technology（防务技术） 2019年第3期15卷 426-431页

作者： hanan A.R. Akkar Wael A.H. Hadi Ibraheem H. Al-Dosari electronic engineering in University of Technology Iraq Communication engineering in University of Technology Iraq electronic engineering at Al-Rafidain University College Iraq

In this paper a square wavelet thresholding method is proposed and evaluated as compared to the other classical wavelet thresholding methods (like soft and hard). The main advantage of this work is to design and implement a new wavelet thresholding method and evaluate it against other classical wavelet thresholding methods and hence search for the optimal wavelet mother function among the wide families with a suitable level of decomposition and followed by a novel thresholding method among the existing methods. This optimized method will be used to shrink the wavelet coefficients and yield an adequate compressed pressure signal prior to transmit it. While a comparison evaluation analysis is established, A new proposed procedure is used to compress a synthetic signal and obtain the optimal results through minimization the signal memory size and its transmission bandwidth. There are different performance indices to establish the comparison and evaluation process for signal compression;but the most well-known measuring scores are: NMSe, eSNR, and PDR. The obtained results showed the dominant of the square wavelet thresholding method against other methods using different measuring scores and hence the conclusion by the way for adopting this proposed novel wavelet thresholding method for 1D signal compression in future researches.

In this work,the oxidation of a mixture of dimethyl ether(DMe) and methyl formate(MF) was studied in both an aqueous electrochemical cell and a vapor-fed polymer electrolyte membrane fuel cell(PeMFC)utilizing a multi-metallic alloy catalyst,Pt_(3)Pd_(3)Sn_(2)/C,discovered earlier by *** current obtained during the bulk oxidation of a DMe-saturated 1 M MF was higher than the summation of the currents provided by the two fuels separately,suggesting the cooperative effect of mixing these fuels.A significant increase in the anodic charge was realized during oxidative stripping of a pre-adsorbed DMe+MF mixture as compared to DMe or MF *** is ascribed to greater utilization of specific catalytic sites on account of the relatively lower adsorption energy of the dual-molecules than of the sum of the individual molecules as confirmed by the density fu nctional theory(DFT) *** cell polarization was also conducted using a Pt_(3)Pd_(3)Sn_(2)/C(anode) and Pt/C(cathode) catalysts-coated membrane(CCM).The enhanced surface coverage and active site utilization resulted in providing a higher peak power density by the DMe+MF mixture-fed fuel cell(123 mW cm^(-2)at 0.45 V) than with DMe(84mW cm^(-2)at 0.35 V) or MF(28 mW cm^(-2)at 0.2 V) at the same total anode hydrocarbon flow rate,temperature,and ambient pressure.
