Vibration characteristics of FGM circular cylindrical shells filled with fluid using wave propagation approach

引用

Applied Mathematics and Mechanics(English Edition) 2009年第11期30卷 1393-1404页

作者： Zafar Iqbal muhammad Nawaz naeem Nazra Sultana Shahid Hussain Arshad Abdul Ghafar Shah Department of Mathematics University of Sargodha Department of Mathematics G. C. University Faisalabad Department of Mathematics University of Sargodha Department of Mathematics The Islamia University of Bahawalpur

The vibration characteristics of a functionally graded material circular cylindrical shell filled with fluid are examined with a wave propagation approach. The shell is filled with an incompressible non-viscous fluid. Axial modal dependence is approximated by exponential functions. A theoretical study of shell vibration frequencies is analyzed for simply supported-simply supported, clamped-simply supported, and clamped-clamped boundary conditions with the fluid effect. The validity and the accuracy of the present method are confirmed by comparing the present results with those available in the literature. Good agreement is observed between the two sets of results.

A novel 1,4,5-trisubstituted 1,2,3-triazole（C18H21N3O3） was synthesized by a one-pot three component reaction of 1-azidocyclohexane, 1-copper（I） phenylethyne and ethoxalyl chloride at room temperature. The molecular structure was determined by single-crystal X-ray analysis. The compound crystallizes in the monoclinic system, space group P21/n with a = 12.8167（9）, b = 8.0966（6）, c = 16.7079（9） A, β = 98.716（2）°, Z = 4 and V = 1713.8（2）. In the crystal, the molecules are related by inversion and paired into dimers via C–H…O and C–O…C interactions involving（oxo） acetate groups. Furthermore, X-ray analysis results are compared with the optimized structure computed by using B3 LYP method with 6-311 G basis set. The calculated results showed that optimized geometry can well reproduce the crystal structure parameters. The bioassay results indicate that the compound has good antibacterial and antifungal activities.

One-pot three component reaction was used to synthesize 1,4,5-trisubstituted 1,2,3-triazole(A) from the corresponding acid chloride, benzyl azide and 1-copper(I) phenylethyne. The molecular structure was determined by single-crystal X-ray analysis. The compound crystallizes in the orthorhombic space group Pbca, a = 14.9815(14), b = 9.6496(10), c = 25.528(2) A, Z = 8. Furthermore, crystal packing demonstrated a molecular wall-like structure based on supramolecular chains of A, stabilized by CH···O, CH···Br, N···C and CH···π interactions. Molecular geometry in the ground state has been determined by density functional theory(DFT) by B3LYP/6-311G* basis set and compared with the experimental data. The computed vibrational frequencies are compared with the experimental FT-IR data and frontier molecular orbital analyses were performed at the same level of theory. Theoretical parameters are in good agreement with the corresponding X-ray diffraction values.

Current methods of ruminant ration formulation in Pakistan use foreign-based nutrient availability *** values may not be optimal for all geographic areas,as variation in environment,agronomic factors,animal species,and diet characteristics may not be *** aim of present study was to establish a database of the chemical composition and dry matter degradation parameters of tropical forage commonly fed to ruminants in Pakistan and South Asian countries using Nili-Ravi buffalo and Cholistani cattle at heifer and lactating *** cereal grain and four legume species were grown in 3 locations under standard agronomic conditions and sampled at booting and at 50%flowering stage for cereal and legumes,*** and milled feeds were analyzed for chemical composition and in situ dry matter degradation parameters using 1 g samples in bags placed in the rumen of 2 Nili-Ravi buffalo heifers,2 lactating Nili-Ravi buffaloes,2 Cholistani heifers,and 2 lactating Cholistani *** forage family(cereal ***),species,and geographic location of growth significantly influenced(P0.05).Legume-by-heifer interactions significantly increased(P<0.05),and legume-by-lactating cow interaction tended(P=0.065),to increase the rate of degradation(Kd).The selected forages were degiaded to a similar extent independent of animal species or developmental stage,and legumes are degraded at higher rates and to a greater extent than are cereals.A moderately significant relationship between Kd and effective dry matter degradability(DMD)suggests tliat Kd co|iild be the single most important predictor of forage degi adability in the rumen.

Reforming of Methane by CO2 over Bimetallic Ni-Mn/γ-Al2O3 Catalyst

引用

Chinese Journal of Chemical Physics 2014年第2期27卷 214-220,I0004页

作者： Anis Hamza Fakeeha muhammad Awais naeem Wasim Ullah Khan Ahmed Elhag Abasaeed Ahmed Sadeq Al-Fatesh 沙特国王大学工程学院化学工程系利雅得11421

γ-Al2O3 supported Ni-Mn bimetallic catalysts for CO2 reforming of methane were prepared by impregnation method. The reforming reactions were conducted at 500-700℃ and atmospheric pressure using CO2/CH4/N2 with feed ratio of 17/17/2, at total flow rate of 36 mL/min. The catalytic performance was assessed through CH4 and CO2 conversions, synthesis gas ratio （H2/CO） and long term stability. Catalytic activity and stability tests revealed that addition of Mn improved catalytic performance and led to higher stability of bimetallic catalysts which presented better coke suppression than monometallic catalyst. In this work, the optimum loading of Mn which exhibited the most stable performance and least coke deposition was 0.5wt%. The fresh and spent catalysts were characterized by various techniques such as Brunauer-Emmett-Teller, the temperature programmed desorption CO2- TPD, thermogravimetric analysis, X-ray diffraction, scanning electron microscope, EDX, and infrared spectroscopy.

Three Tier Fog Networks: Enabling IoT/5G for Latency Sensitive Applications

引用

China Communications 2019年第3期16卷 1-11页

作者： Romana Shahzadi Ambreen Niaz Mudassar Ali muhammad naeem Joel J.P.C.Rodrigues Farhan Qamar Syed muhammad Anwar University Engineering and Technology COMSATS University Islamabad Wah campus National Institute of Telecommunications (Inatel) Instituto de Telecomunicac??es University ITMO University of Fortaleza (Unifor)

Following the progression in Internet of Things(IoT) and 5G communication networks, the traditional cloud computing model have shifted to fog computing. Fog computing provides mobile computing, network control and storage to the network edges to assist latency critical and computation-intensive applications. Moreover, security features are improved in fog paradigm by processing critical data on edge devices instead of data centres outside the control plane of users. However, fog network deployment imposes many challenges including resource allocation, privacy of users, non-availability of programming model and testing software and support for the heterogenous networks. This article highlights these challenges and their potential solutions in detail. This article also discusses threetier fog network architecture, its standardization and benefits in detail. The proposed resource allocation mechanism for three tier fog networks based on swap matching is described. Results show that by practicing the proposed resource allocation mechanism, maximum throughput with reduced latency is achieved.
