Shang, Y. (author), Nogal Macho, M. (author), Wang, Haoyu (author), Wolfert, A.R.M. (author)Performance evaluation and maintenance planning are gaining importance with ageing rail infrastructure and increasing demand on track safety and continuous availability. The discrete/point railway assets (e.g. bridges, level crossings) together with extended track sections constitute the main railway network infrastructure. The former has...journal article 2021

Kammouh, O. (author), Nogal Macho, M. (author), Binnekamp, R. (author), Wolfert, A.R.M. (author)The wellbeing of modern societies is dependent upon the functioning of their infrastructure networks. This paper introduces the 3C concept, an integrative multi-system and multi-stakeholder optimization approach for managing infrastructure interventions (e.g., maintenance, renovation, etc.). The proposed approach takes advantage of the...journal article 2021

Peng, Tian (author), Nogal Macho, M. (author), Casas, Joan R. (author), Turmo, Jose (author)Structural identification using dynamical parameters (such as the natural vibration frequencies and mode shapes) is an important issue, especially in bridges or high-rise buildings. However, incorrect decisions could happen on the Structural Health Monitoring (SHM) strategy and the Structural System Identification (SSI) analysis that makes...journal article 2021

Peng, Tian (author), Nogal Macho, M. (author), Casas, Joan R. (author), Turmo, Jose (author)The inverse problem of structural system identification is prone to ill‐conditioning issues; thus, uniqueness and stability cannot be guaranteed. This issue tends to amplify the error propagation of both the epistemic and aleatory uncertainties, where aleatory uncertainty is related to the accuracy and the quality of sensors. The analysis of...journal article 2021

Nogal Macho, M. (author), Bastidas-Arteaga, Emilio (author), dos Santos Gervásio, Helena Maria (author)The impact of climate change on ambient temperature and relative humidity along with the present CO2 levels are speeding the corrosion process of reinforced concrete structures. The alarming cost of the associated reduction of the service life of structures, which is estimated to cost 3% to 4% of the Gross Domestic Product (GDP) of...conference paper 2021

Habeeb, B. (author), Bastidas-Arteaga, E. (author), Gervásio, H. (author), Nogal Macho, M. (author)Over the Earth’s history, the climate has changed considerably due to natural processes affecting directly the earth. In the last century, these changes have perpetrated global warming. Carbon dioxide is the main trigger for climate change as it represents approximately up to 80% of the total greenhouse gas emissions. Climate change and concrete...conference paper 2021

Kammouh, O. (author), Nogal Macho, M. (author), Binnekamp, R. (author), Wolfert, A.R.M. (author)Probabilistic Monte Carlo simulations are often used to determine a project's completion time given a required probability level. During project execution, schedule changes negatively affect the probability of meeting the project's completion time. A manual trial and error approach is then conducted to find a set of mitigation measures to...journal article 2021

Teixeira, Rui (author), Nogal Macho, M. (author), O'Connor, Alan (author), Martinez-Pastor, Beatriz (author)Reliability assessment with adaptive Kriging has gained notoriety due to the Kriging capability of accurately replacing the performance function while performing as a self-improving function for learning procedures. Recent works on adaptive Kriging pursued to improve the efficiency of the active learning through the application of distinct...journal article 2020

Campos, Neila (author), Nogal Macho, M. (author), Caliz, Cristina (author), Juan, Angel A. (author)Simulation-based education (SE) refers to the use of simulation software, tools, and serious games to enrich the teaching and learning processes. Advances in both computer hardware and software allow for employing innovative methodologies that make use of SE tools to enhance the learning experience. Moreover, thanks to the globalisation of e...journal article 2020

Basu, Bidroha (author), Nogal Macho, M. (author), O'Connor, Alan (author)Estimating reliable projections of precipitation considering climate change scenarios is important for hydrological studies. General circulation models provide future climate simulations at large scale in terms of large-scale atmospheric variables (LSAVs). Those LSAVs can be downscaled to finer special resolution using several downscaling...journal article 2020

Nogal Macho, M. (author)The new generation of structural Eurocodes will include climate change adaption measures in order to enhance the climate resilience of infrastructures across Europe. This paper discusses the impact that climate change might have on reinforced concrete structures subjected to corrosion, and the associated challenges of the standardisation of...conference paper 2020

Kammouh, O. (author), Nogal Macho, M. (author), Cimellaro, Gian Paolo (author), Wolfert, A.R.M. (author)The capacity of a community to react to and resist during an emergency situation is highly related to the proper functioning of its infrastructure systems. Improving the infrastructure response and recovery capacity through management and adaptation strategies can help increase community resilience. Infrastructural assets are considered outdated...conference paper 2020

Kammouh, O. (author), Nogal Macho, M. (author), de Bruijne, M.L.C. (author), Binnekamp, R. (author), Wolfert, A.R.M. (author)Despite widespread attention for the governance of infrastructures and improvements of the way infrastructure assets are maintained, the interdependency of infrastructures is not often considered from a systemic maintenance and renovation perspective. In this context, the issue of unforeseen intervention delays is of particular relevance because...conference paper 2020

O'Kelly, Brendan C. (author), Nogal Macho, M. (author)This paper presents a critical review of the grading entropy approach of permeability-coefficient predictions (k P) for coarse-grained soils. The approach applies the grading entropy theory to particle-size distributions (PSDs), such that the entirety of each gradation curve can be interpreted as a single point on a grading entropy chart,...journal article 2020

Nogal Macho, M. (author), Jiménez, Pilar (author)When analysing the performance of bike-sharing scheme (BSS) stations, it is common to find stations that are located in specific points that capture the interest of users, whereas nearby stations are clearly underused. This uneven behaviour is not totally understood. This paper discusses the potential factors influencing station...journal article 2020
