Among all renewable energy sources, solar holds the greatest potential for electricity production. This transformation from to electrical is facilitated by cells, typically modeled using single-diode, double-diode, and triple-diode representations. In this study, we evaluate effectiveness of Walrus Optimization Algorithm (WOA) estimating parameters these models. Furthermore, introduce three innovative hybrid variants WOA that incorporate chaotic sequences, adaptive modifications, integration with Simulated Annealing (SA) algorithm, thereby enhancing parameter estimation process. Our research was conducted on two well-documented types cells/modules, additional tests performance algorithms a panel under varying insolation temperature conditions. The results underscore superior efficiency, accuracy, practicality algorithms, particularly variant augmented over traditional methods in cell technologies. paper highlights significant advancements algorithmic approaches, paving way more precise reliable

This paper presents a novel approach for the estimation of equivalent circuit parameters proton exchange membrane fuel cells using Walrus optimization algorithm (WaOA) and its hybrid variants: SaWaOA, combined with simulated annealing CWaOA, incorporating chaotic sequences. The evaluation was conducted on two types cells, Ballard-Mark-V 5 kW BCS 500 W. To ensure an objective assessment, validation results performed statistical measures: root mean square error (RMSE), sum squared errors (SSE), absolute error, percentage error. testing carried out by implementing recommended across eight different variants, where boundaries λ Rc were varied during estimation. Results indicate that WaOA variants achieve high precision in parameter estimation, evidenced reduced RMSE SSE values compared to methods from literature. Additionally, influence changing all analyzed, as well effects varying operating temperatures pressures output characteristics tested cells. proposed can significantly enhance accuracy various conditions, opening possibilities broader application industrial transport systems.

We investigate the dynamic effect of external conflict risk on environmental transition by considering impacts eco-innovation, economic growth, and energy consumption in a panel comprising 26 European countries from 2011 to 2020.Using non-parametric model represented QARDL, we find that short run, 1% increase statistically leads 0.25% 0.13% likelihood for median extreme upper quantiles (50th 95th percentiles), respectively.However, same holds little importance when lower quantile (5th percentile).The indicated substantially decreases long reaching zero across different quantiles.We also note discrepancies impact various levels.For instance, population is significant 5th 90th quintiles.Overall, our findings suggest enhancing eco-innovation helps reduce risk.The results are relevant development policies provide valuable insights officials, technology stakeholders, policymakers their attempts strengthen resilience during an transition.

The paper presents a model discussing the political economy dimension of green transition. There are brown sectors whose share in value-added and employment should contract increase. Green technological changes require more skilled workers, potentially exacerbating inequalities between them unskilled workers. Workers unions advocate for "Just Transition", ensuring income protection creating new "green jobs". However, restructuring demands highly subsidized investments short run. A problem arises: how to regulate capitalists, support prevent workers from joining forces with capitalists block solution can be positive feedback technical change, non-price competitiveness, employment. BOPCG allows highlighting role catching up technologies competitiveness endogenous institutional change give rise growth path consistent idea "just transition".

The growing need to address climate change through sustainability governance has amplified the importance of Sustainable Transitions Research (STR). Despite its interdisciplinary scope and methodological variety, STR continues face divisions between research domains, often exacerbated by rapid expansion tensions qualitative quantitative approaches. This study uses natural language processing (NLP) analyse 448 published articles, initiated from two foundational papers, explore thematic semantic patterns within field. NLP analysis reveals underlying connections synergies across theoretical, empirical, conceptual domains in STR, highlighting potential for cross-fertilisation disparate areas. findings map key relationships community, providing a comprehensive overview how different are interlinked. Recommendations include fostering hybrid approaches enhancing collaboration traditions. By bridging these divides, field can advance guiding more effective governance.

In Europe, small and medium-sized cities (SMSCs) face significant challenges related to climate change environmental degradation. France, recent governmental measures have sought accelerate the ecological transition (ET) across its national territory, aiming meet carbon reduction targets preserve biodiversity. Since pandemic, SMSCs been at forefront of this ET policy, benefiting from support programmes designed revitalise neglected city centres. However, several studies already highlighted that, despite being “tailored” specificities each beneficiary city, these are largely inspired by metropolitan models focused on economic growth territorial competitiveness. This article aims highlight that directives applied also derive practices in larger cities, embodying an “institutionalised” conception ecology as part broader attractiveness strategies. An investigation conducted 2021 Rochefort (France) demonstrates policies often utilised tools for enhancing attractiveness, akin promoting tourism industrial development. Using a mixed-method approach includes semi-structured interviews mapping workshops, we will analyse representations aspirations inhabitants regarding future their living environment. help them envision ecologically sustainable socially viable trajectory ascertain whether it differs policies. The objective research is identify alternative action levers beyond concerning ET, distinguishing unique trajectories, thus revealing other comparative advantages, notably size scale primary indicators.
