Miranda, C. (author), Teixeira, A. (author), Huber, M. (author), Schweckendiek, T. (author)The traditional Dutch way to deal with piping failure in river dikes is the implementation of piping berms. The disadvantage of such a measure is the required inland space. Relief wells, on the other hand, require less or no inland space representing an attractive alternative solution. The aims of this paper are first, to show how reliability...conference paper 2015

Miranda, C. (author), Teixeira, A. (author), Huber, M. (author), Schweckendiek, T. (author)Nowadays there is an on-going discussion about piping safety for dikes in the Netherlands. Relief wells represent an attractive solution as mitigation measure against piping, saving hinterland space. Nevertheless, they have been disregarded due to the uncertainties in its performance over its life cycle. The aim of this contribution is to...conference paper 2014

Teixeira, R. (author), O'Connor, A. (author), Nogal Macho, M. (author)The present paper discusses the application principles of value of information theory in adaptive metamodeling for reliability analysis. Metamodeling for reliability purposes has become particularly relevant in recent years. The usage of metamodels allows surrogating the, costly to evaluate, performance functions of engineering structures....conference paper 2021

Stappers, P.J. (author), Teixeira, Carlos (author), Rampino, Lucia (author), Baxter, Weston (author), Hyysalo, Sampsa (author), Chapman, Jonathan (author)In the DoCS4Design project, six established PhD programmes in design pooled and compared the diversity in their practices in guiding PhDs (e.g., 3- or 4-year programmes, small or large amounts of formal education, small or large numbers of staff and students). Panelists from the six programmes discussed these differences to- gether with 60...conference paper 2022

Chockalingam, S. (author), Pieters, W. (author), Teixeira, Andre M. H. (author), Khakzad, N. (author), van Gelder, P.H.A.J.M. (author)Because of modern societies' dependence on industrial control systems, adequate response to system failures is essential. In order to take appropriate measures, it is crucial for operators to be able to distinguish between intentional attacks and accidental technical failures. However, adequate decision support for this matter is lacking. In...conference paper 2019

Rippi, Aikaterini (author), Nuttall, Jonathan (author), Teixeira, Ana (author), Schweckendiek, T. (author)The Dutch design codes for the dikes with retaining walls rely on Finite Element Analysis (FEM) in combination with partial safety factors. However, this can lead to conservative designs. For this reason, in this study, a reliability analysis is carried out with FEM calculations aiming to demonstrate the feasibility of reliability analysis for a...conference paper 2016

Teixeira, Rui (author), Martinez-Pastor, Beatriz (author), Nogal Macho, M. (author), Micu, Alexandra (author), O'Connor, Alan (author)Significant research has been conducted in identifying optimal recovery and adaptation decisions in disruptive scenarios using engineering models. In this context, an aspect that has been target of limited research is that of response times. Modelling is expected to grow progressively more complex as it becomes more accurate. Such complexity...conference paper 2022

(author), Hardeman, B (author)Dikes in the Netherlands are by law required to comply with predefined safety standards. The goal of this paper is to derive the safety format and the required factor of safety for the inner slope (landside slope) instability failure mode. The first step is to derive the required target reliability for a cross-section. The second step is to...conference paper 2017

Gallo, A.J. (author), Anand, S.C. (author), Teixeira, Andre M. H. (author), Ferrari, Riccardo M.G. (author)This paper addresses the design of an active cyberattack detection architecture based on multiplicative watermarking, allowing for detection of covert attacks. We propose an optimal design problem, relying on the so-called output-to-output ℓ 2 -gain, which characterizes the maximum gain between the residual output of a detection scheme and some...conference paper 2021

Geotechnical failure modes are also the main contributors to the probability of failure of flood defenses such as levees due to the large uncertainties in ground conditions. Hence, information on ground conditions and soil...conference paper 2017

Teixeira, Andre M.H. (author), Ferrari, Riccardo M.G. (author)In this paper, the problem of detecting stealthy false-data injection attacks on the measurements is considered. We propose a multiplicative watermarking scheme, where each sensor’s output is individually fed to a SISO watermark generator whose parameters are supposed to be unknown to the adversary. Under such a scenario, the detectability...conference paper 2018

Coupling of a CMOS Optical Sensor to a Micromachined Deformable Mirror with an Adaline Neural MethodDe Lima Monteiro, D.W. (author), Ferreira, A.I. (author), Teixeira, F.B. (author), Melo, J.G.M. (author), Vdovin, G.V. (author)We report on the preliminary results of an Adaline neural method for the coupling of a custom CMOS wavefront sensor to a micromachined adaptive mirror. The algorithm does not rely on a fixed basis matrix -as opposed to traditional methods-, offers excellent immunity to round-off errors and admits real-time input adaptability to speed up...journal article 2006
