Rolling with the resistance to the circular economy: a contribution to sustaina...

Simulating water application efficiency in pressurized irrigation systems: a co...

The agricultural sector faces growing environmental and societal pressures to balance natural resource use with food security, particularly within the Water-EnergyFood-Ecosystems Nexus (WEFE). Increasing water demand, competition, and challenges like droughts and desertification are driving the need for innovative irrigation practices. Pressurized irrigation systems, such as sprinkler and micro-irrigation, are ...

Distributed composite drought index based on principal component analysis and t...

A variety of drought indices were developed to monitor different types of drought, a significant natural hazard with multidimensional impacts. However, no single drought index can capture all dimensions of drought, necessitating a composite drought index (CDI) that integrates a range of indicators. This study proposes a CDI using principal component analysis (PCA) and a temporal dependence assessment (TDA) appl...

Training for sustainable and healthy building for 2050: New methodologies for a...

The development of existing technologies and the emergence of new technologies aiming at the total decarbonization of the buildings sector by 2050 requires and encourages upskilling and reskilling of existing professionals as well as the development of new subjects from higher education courses to be able to respond to the demands of these challenges. In responding to those challenges, the main objective of the...

Optimizing short-term water demand forecasting: a comparative approach within t...

The current paper presents a forecasting methodology for short-term water demand forecasting in the context of the Battle of Water Demand Forecasting. The methodology considers five distinct forecasting techniques, which are compared in terms of their forecasting ability for a preceding period, typically spanning a day or a week. The best-performing model is identified through error assessment between model pre...

NSGA-II parameterization for the optimal pressure sensor location in water dist...

The optimal location of pressure sensors is typicallysolved using heuristic algorithms. Non-dominated Sorting Genetic Algorithm II (NSGA-II) is one of the most used algorithms in the water industry, requiring a preliminary parameter tuning process. The lack of guidelines on how to tune model parameters generally limits the use of these algorithms by researchers or practitioners and, as such, fails to be used in...

A bibliometric analysis of the plastic waste

An information system for infrastructure asset management tailored to portugues...

This paper describes a new information system developed as part of the Portuguese R&D project DECIdE. The project aimed at the development of a platform for infrastructure asset management tailored to Portuguese water utilities. The platform allows the integration of different data from several information systems of the water utilities and includes several tools for the performance assessment of the water supp...

Computational Tools for Supporting the Operation and Management of Water Distri...

This paper presents a set of computational tools specially developed for supporting the operation and management of water distribution systems towards digital transformation of water services. These tools were developed in the scope of two R&D projects carried out in Portugal, DECIdE and WISDom, during 2018–2022. The DECIdE project focused on the development of tools for importing cadastral and operational data...
