    Notes: Abstract  The kinetics of pentachlorophenol (PCP) degradation by a Flavobacterium sp. ATCC 39723 has been investigated. Sodium glutamate was supplied as an additional carbon source to increase the rate of cell growth and PCP degradation. A kinetic model including PCP toxicity for cell growth and PCP inhibition of its own degradation was developed. This model was also applied to 2,4-dichlorophenol (DCP) degradation by the same organism. Although PCP and DCP are degraded by different pathways, the model describes these two degradation processes very well.

    Meshless local Petrov–Galerkin (MLPG) method in combination with finite element and boundary element approaches (2000)
    Springer
    Computational mechanics 26 (2000), S. 536-546

    ISSN: 1432-0924

    Notes: Abstract The meshless local Petrov–Galerkin (MLPG) method is an effective truly meshless method for solving partial differential equations using moving least squares (MLS) interpolants. It is, however, computationally expensive for some problems. A coupled MLPG/finite element (FE) method and a coupled MLPG/boundary element (BE) method are proposed in this paper to improve the solution efficiency. A procedure is developed for the coupled MLPG/FE method and the coupled MLPG/BE method so that the continuity and compatibility are preserved on the interface of the two domains where the MLPG and FE or BE methods are applied. The validity and efficiency of the MLPG/FE and MLPG/BE methods are demonstrated through a number of examples.

    Coupling of element free Galerkin and hybrid boundary element methods using modified variational formulation (2000)
    Springer
    Computational mechanics 26 (2000), S. 166-173

    ISSN: 1432-0924

    Notes: Abstract  A novel method is proposed by coupling the element free Galerkin (EFG) and the hybrid boundary element (HBE) methods to achieve solution efficiency and accuracy for stress analysis in solids. A modified variational formulation is derived for the present coupled EFG/HBE method so that the continuity and compatibility can be preserved on the interface between the domains of EFG and HBE. The coupled EFG/HBE method has been coded in FORTRAN. The validity and efficiency of the proposed method are demonstrated through a number of example problems. It is found that the present method can take advantages of both EFG and HBE methods. The present method is very easy to implement, and very flexible for obtaining displacements and stresses of desired accuracy in solids, as the efforts for meshing the problem domain have been significantly reduced due to the use of boundary element method (BEM).

    Structural shape optimization integrated with CAD environment (1990)
    Springer
    Structural and multidisciplinary optimization 2 (1990), S. 23-28 
    Details
    ISSN: 1615-1488
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The research work presented here is based on the concept of the integration of optimization techniques and numerical analysis with the finite element method (FEM) and computer-aided design (CAD). A microcomputer aided optimum design system, MCADS, has been developed for general structures. Certain techniques to be discussed in the paper, e.g. the semi-analytical method for design sensitivity analysis, optimization analysis modelling for shape design, application oriented user interfaces and the coupling of automated optimization and user intervention have rendered MCADS pratical and versatile in applications for engineering structures. The above techniques and an application are presented in this paper.

    Structural modelling and sensitivity analysis of shape optimization (1993)
    Springer
    Structural and multidisciplinary optimization 6 (1993), S. 29-37 
    Details
    ISSN: 1615-1488
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract It is presented in this paper that the structural modelling of shape optimization is composed of, in general cases, four distinct processes on geometry, design, analysis and perturbation models. The relationships between these models are discussed. An integrated modelling approach based on geometric shape parameterization and automatic mesh generation is proposed. In cooperation with this modelling approach, the semi-analytic sensitivity analysis has been effectively employed. These techniques join shape optimization with FEM and CAD packages and apply it versatilely to optimum designs of general structures. The implementation and applications of the integrated modelling approach and semi-analytic sensitivity analysis to shape optimization of structures with coupling of stress and temperature fields are illustrated.

    Crystalline β-C3N4 synthesized by MPCVD (1999)
    Springer
    Journal of materials science 34 (1999), S. 3117-3125 
    Details
    ISSN: 1573-4803

    Notes: Abstract Carbon nitride films were grown on Si and Pt substrates by microwave plasma chemical vapor deposition (MPCVD) method. Scanning electron microscope (SEM) observations show that the films deposited on Si substrates consisted of densely populated hexagonal crystalline rods. Energy dispersive X-ray (EDX) analyses show that N/C ratios of the rods were in the range of 1.0 to 2.0 depending on deposition condition. X-ray diffraction experiments show that the films consisted of crystalline phase β-C3N4. Comparison with films grown on Pt substrate show that the main X-ray diffraction peaks of β-C3N4 are existed in films deposited on both substrate. XPS study showed that carbon and nitride atoms are covalent bounded to each other. IR results show that the film is predominantly C-N bonded. Raman measurement showed characteristic peaks of β-C3N4 in the low wave number region. Temperature dependent growth experiments show that the amount of Si3N4 in the films grown on Si substrates can be significantly reduced to negligible amount by controlling the substrate temperature.
