To overcome these limitations, a modified SSSS that integrates interfacial heating (IH) and photovoltaic (PV)-assisted seawater circulation was developed and evaluated.

The objective of this study is to systematically investigate the thermal behavior, freshwater yield, and energy efficiency of the integrated SSSS-IH system and compare it with that of the conventional configuration.

Maximum productivity reached 9.31 L·m⁻²/day. Water quality analysis confirmed that the distilled water met clean water standards, reducing the salinity from 32,300 ppm to below 60 ppm.

The analysis reveals four key findings. First, diverse configurations of entrepreneurial traits generate multiple pathways to achieve green entrepreneurial performance, highlighting the importance of considering trait combinations rather than individual attributes. Second, social capital, prior engineering experience, and green innovativeness emerge as pivotal factors; social capital is present in five performance configurations, playing a central role in high-performance outcomes, while prior experience and green innovativeness feature in four configurations. Third, startups can attain strong green performance by leveraging substantial social capital, rich prior experience, and proactive green innovativeness, even with relatively moderate psychological traits. Fourth, a high degree of green innovativeness significantly enhances performance, underscoring its value in driving technological advancements within the engineering green entrepreneurship space.

AE signal characteristics, such as event count, amplitude, and hit rate, are directly linked to fatigue progression and allow real-time tracking of critical damage stages. However, traditional feature-based methods often suffer from noise and interference from work hardening and user-defined settings, reducing accuracy. This study introduces an adaptive threshold waveform processing method that filters noise and enhances high-energy events. Analyzing these signals with the Bhattacharyya coefficient (BC) enables real-time fatigue assessment. Fatigue tensile-compression tests were conducted on medium-carbon steel, with concurrent real-time recording of surface temperature changes in the specimens. During the slow crack growth phase, an increase in local temperature corresponded with a turning point in the BC evolution trend, indicating that this method can reliably reflect the fatigue damage state of structures in real time. The effectiveness of the proposed method was validated through high-cycle fatigue experiments, demonstrating its applicability in practical fatigue damage scenarios. Furthermore, the computational cost analysis indicates that the proposed AHIE+BC framework achieves a data compression rate of approximately 20%, significantly reducing the computational burden while maintaining effective damage representation.

Erosive wear caused by sediment-laden water, significantly impacts turbine efficiency, time between overhaul and service life. While surface coatings and operational adjustments, like shutdowns during high sediment concentration events, offer some mitigation, damage assessment still relies on visual inspections and associated downtime. This study aims to understand the dynamic behaviour of a prototype Pelton runner by examining the influence of boundary conditions as well as the hub and bucket designs on the runner's vibration modes. Additionally, four erosion scenarios are investigated through numerical modal simulations on a single bucket geometry, by removing material from specific erosion-affected locations. The results indicate a weak correlation between main splitter erosion and frequency shifts for all modes. The most realistic erosion scenario, which includes the erosion of a large surface in the bucket intrados, reveals the balanced effect of mass loss and stiffness reduction resulting from material removal. Consequently, most vibration modes remain unaffected by this realistic scenario, except two modes which show significant frequency shifts. These findings enhance the understanding of the dynamic behaviour of Pelton turbines. Moreover, understanding the impact of common wear on Pelton runners is crucial for developing advanced vibration-based monitoring tools that would enhance turbine safety and minimize downtime.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"27 ","pages":"Article 105638"},"PeriodicalIF":6.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144299000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stainless steel RC beams tend to exhibit larger deflections under comparable loading conditions than their carbon steel counterparts, owing mainly to the lower bond strength and nonlinear stress-strain response. Since the serviceability limit state often governs the design of RC members, there is a critical need for simplified and accurate deflection prediction methods specifically tailored for stainless steel reinforcement. Current global design codes lack explicit provisions for stainless steel RC members, typically neglecting the unique nonlinear and strain-hardening behavior of stainless steel. To address this limitation, the present study compiles an extensive experimental database of 150 stainless steel RC beam specimens from the literature and evaluates the deflection predictions of established design codes, including ACI 318-19 and Eurocode 2. Building upon this analysis, a modified design approach is proposed. A reliability analysis demonstrates the enhanced accuracy and robustness of the proposed method, offering a more dependable tool for deflection estimation in stainless steel RC beams under service loads. The results show that the mean predicted-to-experimental deflection ratios at 30 % of ultimate moment were 0.98 (EC2), 0.77 (ACI), and 0.99 (proposed). Whereas at 67 %, both EC2 and the proposed method achieved 0.88, outperforming ACI at 0.75.
