Abstract: A constructive algorithm is proposed and illustrated for parametric estimation in delayed nonlinear time-varying dynamic system models from available data. The algorithm uses Chebyshev spectral ...

Abstract: A constructive optimization algorithm using Chebyshev spectral collocation and quadratic programming is proposed for unknown parameter estimation in nonlinear time-varying dynamic system models to ...

Abstract: A constructive algorithm using Chebyshev spectral collocation is proposed for computing trustworthy approximate solutions of linear and weakly nonlinear delayed partial differential equations or ...

Abstract: The management and regulation of hazardous waste sites are increasingly being carried out by assessing risks via different exposure pathways. The selection of an appropriate multimedia fate and transport for carrying out ...

Abstract: Extensive and rigorous wear tests involving the failure criterion were carried out initially on (i) TiC coated and (ii) uncoated cemented tungsten carbide, and (iii) cemented titanium carbide ...

Abstract: Tool life curves were plotted for HSS, cemented tungsten carbides, coated carbides, and cemented titanium carbides. HSS tools showed a distinct inflection coinciding with the formation of a white ...

Abstract: Fractional differential equations with time varying coefficients and delay are encountered in the analysis of models of metal cutting processes such as milling and drilling with viscoelastic damping elements. Viscoelastic ...

Abstract: There is anecdotal evidence that the adoption of building information modeling (BIM) is on the increase. However, the extent to which quantity surveyors (QS) (also referred to as cost consultants or cost engineers) are now ...
