Smart Cities, Journal Year: 2023, Volume and Issue: 6(5), P. 2849 - 2882

Published: Oct. 18, 2023

Global urbanization and increasing water demand make efficient resource management crucial. This study employs Multi-Criteria Decision Making (MCDM) to evaluate smart city strategies. We use representative criteria, employ objective judgment, assign weights through the Analytic Hierarchy Process (AHP), score strategies based on meeting these criteria. find that “Effectiveness Risk Management” criterion carries highest weight (15.28%), underscoring its pivotal role in strategy evaluation robustness. Medium-weight criteria include “Resource Efficiency, Equity, Social Considerations” (10.44%), “Integration with Existing Systems, Technological Feasibility, Ease of Implementation” (10.10%), “Environmental Impact” (9.84%) for ecological mitigation. “Community Engagement Public Acceptance” (9.79%) recognizes involvement, while “Scalability Adaptability” (9.35%) addresses changing conditions. “Return Investment” (9.07%) “Regulatory Policy Alignment” (8.8%) balance financial governance concerns. Two low-weight “Data Reliability” (8.78%) “Long-Term Sustainability” (8.55%), stress data accuracy sustainability. Highly weighted like “Smart Metering Monitoring, Demand Management, Behavior Change” Irrigation Systems” are particularly effective improving cities. However, medium-weighted (e.g., “Educational Campaigns Awareness”, “Policy Regulation”, “Rainwater Harvesting”, “Offshore Floating Photovoltaic Systems”, “Collaboration Partnerships”, “Graywater Recycling Reuse”, “Distributed Water Infrastructure”) low-weighted “Water Desalination”) also contribute can be combined higher-ranked ones create customized approaches each city’s unique context. research is significant because it urban complexity, offers a multi-criteria approach enhance traditional single-focused methods, evaluates cities comprehensively, provides criteria-weight-based allocation framework sustainable decisions, boosting resilience. Note results may vary specific needs constraints. Future studies could explore factors climate change consider alternative MCDM methods TOPSIS or ELECTRE evaluation.

A review of the state-of-the-art wastewater quality characterization and measurement technologies. Is the shift to real-time monitoring nowadays feasible?

Journal of Water Process Engineering, Journal Year: 2024, Volume and Issue: 60, P. 105061 - 105061

Efficient characterization of wastewater stream quality is vital to ensure the safe discharge or reuse treated (WW). There are numerous parameters employed characterize water quality, some required by directives (e.g. biological oxygen demand (BOD), total nitrogen (TN), phosphates (TP)), while others used for process controls flow, temperature, pH). Well-accepted methods assess these have traditionally been laboratory-based, taking place either off-line at-line, and presenting a significant delay between sampling result. Alternative can run in-line on-line, generally being more cost-effective. Unfortunately, often not accepted when providing information regulatory bodies. The current review aims describe available laboratory-based approaches compare them with innovative real-time (RT) solutions. Transitioning from RT measurements means obtaining valuable data, avoiding time delays, possibility optimize (WW) treatment management. A variety sensor categories examined illustrate general framework in which applications replace longer conventional processes, an eye toward potential drawbacks. enhancement be achieved through employment advanced soft-sensing techniques Internet Things (IoT), coupled machine learning (ML) artificial intelligence (AI).

Connecting Cities: A Case Study on the Application of Morphological Shortest Paths

Symmetry, Journal Year: 2025, Volume and Issue: 17(1), P. 114 - 114

Published: Jan. 13, 2025

Navigatingdensely connected networks can be complex due to the different connection structures present within a network. No explicit algorithms are designed specifically for this navigation, so heuristic approaches and existing network systems often employed. However, task become computationally asymmetrical, as complexity of creating representation city is lower than involved in identifying set feasible paths combinatorial order. This paper extends applicability morphological compute shortest path smart cities, driven by size vital communication infrastructure. As well known, infrastructure changes dynamically, particularly with evolving continuous population growth. Consequently, efficient trajectories quickly obsolete. The challenge computing best respond more growing comes high computational complexity. presents an application that uses discrete algorithm through approach. Specifically, it seeks identify trajectory densely populated based on density graph. By incorporating into path-search algorithms, we define new family methods operate spaces representation, resulting have requirements. Other well-known applications context include delivery resources, such managing electrical power consumption or minimizing time delays resource delivery. essential but classified NP problem, making appropriate scenario applying proposed navigate dense highlights problem finding one potential introduced algorithm. aims optimal graph representing city’s real scenario. discussion compares contrasts proposal other established approaches, highlighting advantages characteristics method.
