On the response of shock-induced separation bubble to small amplitude disturbances (2005)
Journal Article
Krishnan, L., Yao, Y., Sandham, N. D., & Roberts, G. T. (2005). On the response of shock-induced separation bubble to small amplitude disturbances. Modern Physics Letters B, 19(28-29), 1495-1498. https://doi.org/10.1142/S0217984905009742

Numerical simulations of an oblique shock interacting with a compressible laminar boundary layer are reported. The Mach number ranges from 2 to 6.85, while the Reynolds number based on the distance to the impingement location is fixed at 3 × 105. All...

Basic perfect graphs and their extensions (2005)
Journal Article
Zverovich, V. E., Zverovich, I. E., & Zverovich, V. (2005). Basic perfect graphs and their extensions. Discrete Mathematics, 293(1-3), 291-311. https://doi.org/10.1016/j.disc.2004.08.033

In this article, we present a characterization of basic graphs in terms of forbidden induced subgraphs. This class of graphs was introduced by Conforti et al. (Square-free perfect graphs, J. Combin. Theory Ser. B, 90 (2) (2004) 257-307), and it plays... Read More about Basic perfect graphs and their extensions.

One point quadrature shell element with through-thickness stretch (2005)
Journal Article
Cardoso, R. P., & Yoon, J. W. (2005). One point quadrature shell element with through-thickness stretch. Computer Methods in Applied Mechanics and Engineering, 194(9-11), 1161-1199. https://doi.org/10.1016/j.cma.2004.06.017

A general purpose one point quadrature shell element accounting for through-thickness deformation is developed. In the shell, a complete 3-D constitutive law is introduced, leading to a 7-parameter theory which explicitly accounts for thickness chang...

A new one-point quadrature enhanced assumed strain (EAS) solid-shell element with multiple integration points along thickness: Part I - Geometrically linear applications (2005)
Journal Article
Natal Jorge, R. M., Grácio, J. J., Fontes Valente, R. A., Alves de Sousa, R. J., Sousa, R., Cardoso, R. P., …Natal, R. (2005). A new one-point quadrature enhanced assumed strain (EAS) solid-shell element with multiple integration points along thickness: Part I - Geometrically linear applications. International Journal for Numerical Methods in Engineering, 62(7), 952-977. https://doi.org/10.1002/nme.1226

Accuracy and efficiency are the main features expected in finite element method. In the field of low-order formulations, the treatment of locking phenomena is crucial to prevent poor results. For three-dimensional analysis, the development of efficie...

Tikhonov regularisation in discrete vortex methods (2005)
Journal Article

In this study we propose the Tikhonov regularisation technique as a useful tool in discrete (blob) vortex methods (DVM). The effectiveness of Tikhonov technique is illustrated for the case of a specific blob vortex method, although the idea may be ap...

Rolling horizon heuristics for production planning and set-up scheduling with backlogs and error-prone demand forecasts (2005)
Journal Article
Clark, A. R., & Clark, A. (2005). Rolling horizon heuristics for production planning and set-up scheduling with backlogs and error-prone demand forecasts. Production Planning and Control, 16(1), 81-97. https://doi.org/10.1080/09537280412331286565

Three families of models and fast heuristic methods are developed for identifying a production plan and immediate set-up schedule for a manufacturing line with changeover times. The initial model is exact, but is optimally solvable only for very shor...
