Gentrification occurs when there is a physical displacement of people with lower socioeconomic status, because they cannot cope with the rising cost of living caused by the influx of new neighbors with higher status. This paper proposes to cluster areas according to their degree of gentrification based on 46 features, by using the K-means machine l...

Geopolitical and health crises slow down global economic activities. This triggers atypical price increases in food and energy, aggravating inflation, exacerbating pressures in the supply chain, pushing millions of people into hunger and poverty, and increasing political uncertainty, financial market vulnerability, and environmental impacts—because...

In this study, we examine Society 5.0, defined as a future framework where advanced technologies like artificial intelligence (AI), the Internet of Things (IoT), and other digital innovations are integrated into society for sustainable resource management. Society 5.0 represents an evolution from the industrial focus of Industry 4.0, aiming for a h...

This study presents a mathematical programming approach for the strategic planning of electrical energy production. The proposed approach seeks the optimal selection of conventional and clean technologies and their production capacity in a given period. In addition, it aims to assess the amount of emissions generated and water consumption, without...

The effects of climate change, such as droughts and decreased rainfall, as well as population growth and globalization are aggravating the availability of water, energy and food. As a result, meeting the population's demand will be a major challenge in the near future. For this reason, assessing the situation of the water-energy-food (WEF) nexus is...

Water, energy and food (WEF) are experiencing significant stress due to an increase in their demand and scarcity, and this situation will worsen in the coming years. For this reason, this paper proposes a WEF nexus index, which consists of 6 indicators of availability and accessibility to measure water, energy and food security. The proposed method...

A titanium (Ti) commercial cathode material and high purity Ar and O2 were used in the cathodic arc physical vapor deposition (arc-PVD) process. The TiOx coating was deposited on the three sets of Raschig rings using decreasing ratios of Ar/O2:440/60, 400/100 and 300/100. The cross sections of the TiOx PVD coating were analyzed using field emission...

Assessing the security of the water-energy-food nexus is a topic of great importance, which allows determining the situation of each resource to implement actions for sustainable management of these resources in today's society. For this reason, a systematic procedure is proposed to evaluate the synergies of the water-energy-food nexus in a large r...
