The interaction between groundwater and civil engineering works is a key aspect in geotechnical design. In the case of excavations confined sheet pile walls, steel sheeting, diaphragm cut-off or cofferdams, this design requires estimation, among other soil mechanics properties, flowing into excavation (seepage) caused by piezometry depletion. Numerical methods, graphical solutions, analytical p...

In this paper, we propose a general class of penalized profiled semiparametric estimating functions which is applicable to a wide range of statistical models, including quantile regression, survival analysis, and missing data, among others. It is noteworthy that the estimating function can be non-smooth in the parametric and/or nonparametric components. Without imposing a specific functional st...

This paper describes the investigations and results of an analysis distortion compensation processes for profile grinding. Steel workpieces often change their residual stress state due to machining in a seemingly uncontrolled matter. Furthermore, research as well industry, accurate representation shape deviations during cutting slim profiled deformation handling is major challenge. In this pape...

This paper presents the results of a study aiming at shape optimising singly-symmetric cold-formed steel purlins. The “self-shape” optimisation algorithm previously developed, proven to be robust and converge known solutions is used for this purpose. Eight cases are considered, consisting 1.5 mm 1.9 thick purlins, spanning either 3000 or 8000 drawn with 4, 6 8 elements per half cross-section. a...
