The thermal influence of the Rooftop Building-Integrated Solar Photovoltaic (RBISPV) has been investigated through experimental configurations employing a solar panel alongside a MDF wooden panel for data collection. The study investigated the Bottom Surface Temperature of the panels (BST), the Rooftop Surface Temperature (RST) located beneath both panels, and at a distance of 1 meter from both panels. Readings were taken at three specific intervals: between sunrise and noon (T1); at noon (T2); and between noon and sunset (T3), during the summer and winter seasons in Bahrain, and analyzed across both panels. The findings indicate that in the summer season, the BST of the solar panel consistently surpassed that of the MDF wooden panel, exhibiting temperature differentials of 10.73 °C at (T1), 12.38 °C at (T2), and 4.22 °C at (T3). In the winter season, the solar panel exhibited heightened BST readings, reflecting differences of 9.55 °C at T1, 11.30 °C at T2, and 3.68 °C at T3. In contrast, the measurements of RST beneath the solar panel exhibited an increase of 3 °C and 1.4 °C during the summer, and an elevation of 1 °C and 0.7 °C in the winter, corresponding to (T1) and (T2), respectively. At (T3), the RST beneath the MDF wooden panel showed increases of 0.5 °C and 0.1 °C relative to the area beneath the solar panel in summer and winter, respectively. Measurements taken at a distance of 1 meter from the panels indicated that the temperatures adjacent to the solar panel rose by 0.9 °C and 1.6 °C in summer, and by 0.6 °C and 3.5 °C in winter, during (T2) and (T3), respectively. During (T1), the temperature adjacent to the MDF wooden panel recorded at a higher value of 2.1 °C in contrast to that near the solar panel. The results reveal a significant accumulation of heat from the RBISPV. Moreover, it emphasizes methods to reduce heat buildup on solar panels, as this thermal phenomenon contributes to the Urban Heat Island (UHI) effect, resulting in various negative environmental consequences, such as changes in weather patterns and global warming.

屋顶建筑集成太阳能光伏（RBISPV）的热影响已经通过实验配置进行了研究，该实验配置采用太阳能电池板和MDF木板进行数据收集。该研究调查了面板的底部表面温度（BST），位于面板下方的屋顶表面温度（RST），距离面板1米。读数在三个特定的间隔进行：日出和中午之间（T1）；中午（T2）；中午和日落（T3）之间，在巴林的夏季和冬季，并通过两个面板进行分析。结果表明，在夏季，太阳能板的BST始终优于MDF木板，在（T1）、（T2）和（T3）表现出10.73°C、12.38°C和4.22°C的温差。在冬季，太阳能电池板显示出较高的BST读数，反映了T1时9.55°C、T2时11.30°C和T3时3.68°C的差异。相比之下，太阳能电池板下的RST测量值在夏季分别增加了3°C和1.4°C，在冬季分别升高了1°C和0.7°C，分别对应于（T1）和（T2）。在（T3）， MDF木板下的RST在夏季和冬季分别比太阳能板下面积增加0.5°C和0.1°C。在距离电池板1米的地方进行的测量表明，在（T2）和（T3）期间，太阳能电池板附近的温度在夏季分别上升0.9°C和1.6°C，在冬季分别上升0.6°C和3.5°C。在（T1）期间，与靠近太阳能板的温度相比，MDF木板附近的温度记录在2.1℃的较高值。结果显示，从RBISPV显著的热量积累。此外，它强调了减少太阳能电池板上热量积聚的方法，因为这种热现象有助于城市热岛效应，导致各种负面的环境后果，如天气模式的变化和全球变暖。

This study presents a novel 3D geospatial modeling framework designed to assess the spatiotemporal dynamics of dissolved heavy-metal contamination of lead (Pb), cadmium (Cd), and arsenic (As) in the Shafa Badran corridor (Zarqa River Basin, Jordan). The approach integrates Geographic Information System (GIS)–based spatial interpolation (inverse distance weighting and ordinary kriging), hydrologic flow-path analysis from Digital Elevation Models (DEMs), and a calibrated one-dimensional advection–dispersion equation (ADE) for a long-channel transport. Field measurements indicate pronounced clustering of Pb and Cd within industrial reaches and broader As plumes aligned with irrigation return flows. Compared with World Health Organization (WHO) guideline values, Pb shows frequent exceedances and Cd occasional exceedances, while As is generally at or below 10 µg L⁻¹. Source attribution is routing-consistent: industrial hotspots co-locate with mapped outfalls; diffuse signatures align with irrigated belts. Forecasts suggest that absent mitigation measures, elevated concentrations persist through 2035 along priority segments. Uncertainty is quantified via kriging variance, cross-validation diagnostics, and ADE prediction envelopes from parameter perturbation; these are propagated into decision-oriented risk layers to distinguish screening from management priorities. Scenario analysis indicates that combining industrial pre-treatment at discharge nodes with nature-based polishing at return-flow confluences can substantially reduce along-channel concentrations and guideline exceedance probabilities. The study therefore provides a routing-consistent fusion of 3D voxel-based geostatistics with a calibrated 1D ADE, yielding two-year exceedance-probability maps, end-to-end uncertainty envelopes, and scenario-based risk reductions (S0–S3) resolved along hydrologic flow paths. The workflow converts technical forecasts into operational management surfaces that can guide stepwise interventions in similar semi-arid, data-constrained urban–industrial watersheds.

本研究提出了一种新的三维地理空间建模框架，旨在评估约旦扎卡河流域沙法巴德兰走廊溶解重金属铅（Pb）、镉（Cd）和砷（As）污染的时空动态。该方法集成了基于地理信息系统（GIS）的空间插值（逆距离加权和普通克里格法）、来自数字高程模型（dem）的水文流道分析，以及用于长通道运输的校准一维平流-弥散方程（ADE）。实地测量表明，铅和镉在工业范围内明显聚集，更广泛的砷羽流与灌溉回流对齐。与世界卫生组织（WHO）的指导值相比，Pb经常超标，Cd偶尔超标，而As一般在10µg L−1以下。来源归属是路由一致的：工业热点与映射的出口位于同一位置；漫射信号与灌溉带一致。预测表明，如果没有缓解措施，高浓度将持续到2035年。不确定性通过克里格方差、交叉验证诊断和参数扰动的ADE预测包络来量化；这些被传播到面向决策的风险层，以区分筛选和管理优先事项。情景分析表明，将排放节点的工业预处理与回流汇合处的自然抛光相结合，可以显著降低沿通道浓度和指南超标概率。因此，该研究提供了基于3D体素的地质统计数据与校准的1D ADE的路由一致的融合，产生了两年的超越概率图，端到端不确定性包线，以及基于场景的风险降低（S0-S3）沿着水文流动路径解决。该工作流程将技术预测转化为操作管理界面，可以指导在类似的半干旱、数据受限的城市工业流域进行逐步干预。

Road widening is a common solution to congestion problems, but widening projects may negatively affect local communities and environment due to loss of private property or the relocation or removal of structures and trees. Literature reports that engaging the community and understanding the perspectives of affected stakeholders can help mitigate risks and ensure the successful completion of road development projects, but there are few studies that explore the intersection of public perception and socio-environmental impacts for road widening projects. This paper presents an empirical study of a suspended road widening project in the Philippines wherein Q methodology is applied to characterize subjective stakeholder perspectives on the project. In total, four distinct viewpoints were identified: road infrastructure drivers, transportation savvy, uncompromising environmentalists, and people-oriented. The major areas of disagreement between these viewpoints revolved around the trade-off between environmental preservation and improved mobility, as well as the role of public consultation. However, all groups shared a common distrust in the government. The results present new insights into the implications of road widening projects for local communities and environments, particularly with regards to the need for a holistic understanding of stakeholders’ perspectives during the project planning and implementation stages. Q methodology was also demonstrated as an effective method for systematically revealing the subjective perspectives of the stakeholders, but future work should explore how an understanding of these perspectives may be leveraged to improve project planning and implementation.

扩阔道路是解决挤塞问题的常用方法，但扩阔工程可能会损失私人财产，或搬迁或拆除建筑物和树木，从而对当地社区和环境产生负面影响。文献报道，让社区参与并理解受影响利益相关者的观点有助于降低风险并确保道路开发项目的成功完成，但很少有研究探讨道路拓宽项目中公众认知和社会环境影响的交集。本文提出了一个在菲律宾暂停道路拓宽项目的实证研究，其中Q方法被应用于表征项目的主观利益相关者的观点。总共确定了四种不同的观点：道路基础设施司机，交通精明，不妥协的环保主义者和以人为本。这些观点之间的主要分歧在于环境保护与改善流动性之间的权衡，以及公众咨询的作用。然而，所有团体都对政府有一个共同的不信任。研究结果为道路拓宽项目对当地社区和环境的影响提供了新的见解，特别是在项目规划和实施阶段需要全面了解利益相关者的观点。Q方法也被证明是一种系统地揭示利益相关者主观观点的有效方法，但未来的工作应该探索如何利用对这些观点的理解来改进项目规划和实施。

The global proliferation of state-led smart city initiatives in climate-vulnerable river deltas has created a significant development-resilience paradox. The political and economic pressures for rapid urbanization often favor conventional, gray infrastructure, which fragments landscapes, increases imperviousness, and ultimately undermines the city’s long-term resilience to flooding. Current scholarship often examines green infrastructure and smart technology as separate solutions, but lacks integrated frameworks designed to resolve this fundamental conflict within the unique governance context of fast-growing SouthEast-Asian cities. This paper confronts this gap by framing Thu Duc City (TDC), Viet Nam, as a living laboratory for studying and resolving this paradox. Employing a robust analytical approach that includes GIS, spatial analysis, and detailed hydrological modeling (EPA-SWMM, MIKE FLOOD), our research first quantifies the adverse impacts of TDC’s accelerated development on its water systems. We then propose a novel, integrated framework that systematically resolves the paradox. This framework uses smart technology (IoT sensors, predictive analytics) to dynamically manage and optimize the performance of nature-based green infrastructure, transforming urban resilience from a static defense into an adaptive, responsive system. Ultimately, this research offers a replicable model for urban planners and policymakers to navigate the trade-offs between development and resilience, providing a pathway for a new generation of smarter, more sustainable cities.

在易受气候影响的河流三角洲地区，国家主导的智慧城市倡议在全球范围内的扩散，造成了一个重大的发展与韧性悖论。快速城市化的政治和经济压力往往有利于传统的灰色基础设施，这些基础设施会破坏景观，增加不透水性，最终破坏城市对洪水的长期抵御能力。目前的学术研究通常将绿色基础设施和智能技术作为独立的解决方案，但缺乏旨在在快速发展的东南亚城市的独特治理背景下解决这一根本冲突的综合框架。本文通过将越南的Thu Duc市（TDC）作为研究和解决这一悖论的活实验室，来解决这一差距。采用强大的分析方法，包括地理信息系统，空间分析和详细的水文模型（EPA-SWMM, MIKE FLOOD），我们的研究首先量化了TDC加速发展对其水系统的不利影响。然后，我们提出了一个新颖的、综合的框架来系统地解决这个悖论。该框架使用智能技术（物联网传感器、预测分析）来动态管理和优化基于自然的绿色基础设施的性能，将城市弹性从静态防御转变为自适应响应系统。最终，这项研究为城市规划者和政策制定者提供了一个可复制的模型，以便在发展和弹性之间进行权衡，为新一代更智能、更可持续的城市提供了一条途径。

Current pedestrian illumination practices prioritise sufficient lighting on surfaces using photometric parameters regardless of context. Real-world environments are complex, comprising built and natural elements fluctuating in response to natural phenomena. In higher latitudes, snowfall coincides with the darkest period of the year, offering a distinctive context for examining interactions among light, materiality, and the environment. This exploratory study investigates the influence of snow cover, as a reflective material on pedestrian path illumination within a peri-urban green space. The research was conducted at a testbed in Uppsala, Sweden, using a mixed-methods approach combining photometric measurements (illuminance and luminance), with self-reported questionnaires completed by residents. The study’s findings indicate that significantly reduced light output under snow-covered conditions elevates light levels at distances of four to twenty metres along the path to values comparable with those produced under full light output (2100 lm) on dry surfaces. Increased snow depth correlates with a nearly fourfold increase in reflectance, supporting sufficient landscape visibility even in low-lit environments. Self-reported resident responses revealed complex public attitudes toward light and darkness: snow-covered settings were generally perceived positively, with appreciation expressed for enhanced celestial visibility and wildlife protection. However, reassurance perceived through electric lighting remained significant. Overall, the findings suggest the need to implement responsive mitigation strategies that account for material conditions and leverage technological adaptability to ensure both visibility and ecological protection. By linking quantified lighting effects to spatial, social, and ecological dimensions, the study supports a context-specific approach to lighting design that is attuned to ecological rhythms and variations in human perception.

目前的行人照明实践优先考虑使用光度参数在表面上提供足够的照明，而不考虑环境。现实世界的环境是复杂的，包括随着自然现象而波动的建筑和自然元素。在高纬度地区，降雪与一年中最黑暗的时期相吻合，为研究光线、物质和环境之间的相互作用提供了独特的背景。本探索性研究探讨了积雪作为一种反射材料对城市周边绿地中行人路径照明的影响。该研究在瑞典乌普萨拉的一个试验台进行，采用混合方法结合光度测量（照度和亮度），并由居民完成自我报告的问卷调查。研究结果表明，在积雪覆盖的条件下，显著减少的光输出将沿着路径4到20米的距离提升到与在干燥表面上全光输出（2100 lm）下产生的光水平相当的值。积雪深度的增加与反射率增加近四倍相关，即使在低光照环境中也能提供足够的景观能见度。居民自我报告的反应揭示了公众对光明和黑暗的复杂态度：白雪覆盖的环境通常被认为是积极的，对提高天空能见度和保护野生动物表示赞赏。然而，通过电力照明感受到的安心仍然很重要。总体而言，研究结果表明，需要实施响应性缓解战略，考虑到物质条件并利用技术适应性，以确保能见度和生态保护。通过将量化的照明效果与空间、社会和生态维度联系起来，该研究支持了一种适应生态节奏和人类感知变化的特定环境的照明设计方法。

Background

The rapid rise of padel in Europe, and of pickleball in North America, has created noise-related land-use conflicts in residential areas. Guidance recommends minimum setback distances, yet there has been no nationwide assessment of how many sites fall short or which populations may be exposed. We develop a GIS screening approach that combines proximity (edge-to-edge distance) and visibility (line-of-sight, LoS) to flag potentially high-exposure configurations and quantify affected residents, framed by urban-morphology and environmental-justice debates.

Methods

We compiled a database of 878 active padel sites in metropolitan France from open sources, geocoded each site, and classified them by distance from the nearest dwelling and presence of effective built screens. For sites falling short of recommended setbacks (Class 1), we identified residential buildings within 100 m, determined LoS, and allocated population and households to buildings by dasymetric floor-area weighting of INSEE 200 m grid data. The screen deliberately trades acoustic modelling for scalability and transparency.

Results

Nearly one third of sites (271/878, 30.9%) were Class 1, with higher concentrations in lower-density communes. Across these sites we identified an estimated 17,100 residents living within 100 m of a padel court. Buildings with direct LoS were closer on average than screened buildings and accounted for most residents within 50 m.

Conclusions

Combining proximity and visibility in a GIS screen pinpoints where racket-sport noise exposure is most plausible. The results support context-modulated setbacks, distance-triggered acoustic studies, and post-implementation follow-up, and offer planners a reproducible, low-cost tool that complements detailed acoustic modelling.

欧洲桌球运动和北美匹克球运动的迅速兴起，在居民区造成了与噪音有关的土地使用冲突。指南建议最小后退距离，但没有对有多少地点达不到要求或哪些人群可能受到影响进行全国性评估。我们开发了一种GIS筛选方法，结合了接近性（边缘到边缘距离）和可见性（视线，LoS）来标记潜在的高暴露配置并量化受影响的居民，并在城市形态和环境正义辩论的框架下进行。方法从开放资源中收集法国大都市878个活跃的模式站点，对每个站点进行地理编码，并根据与最近住所的距离和有效构建屏障的存在进行分类。对于未达到推荐退距（1类）的站点，我们确定了100米内的住宅建筑，确定了LoS，并通过INSEE 200米网格数据的非对称面积加权将人口和家庭分配到建筑物中。屏幕故意用声学模型来换取可扩展性和透明度。结果近1/ 3的地点（271/878,30.9%）为1类，在低密度群落中浓度较高；在这些地点中，我们发现大约有17,100名居民居住在一个样板庭院的100米范围内。直接LoS的建筑物比屏蔽的建筑物平均距离更近，并且在50米内的居民占大多数。结论：结合地理信息系统屏幕上的接近性和可视性，确定了球拍运动噪音暴露最合理的地方。研究结果支持环境调节挫折、距离触发声学研究以及实施后的跟踪，并为规划人员提供了一种可重复、低成本的工具，补充了详细的声学建模。

Tehran is grappling with a host of unique urbanization challenges that require innovative spatial planning practices that transcend conventional top-down spatial planning. This Short Communication presents a conceptual proposal for a novel synthesis: combining Gamified Co-creation with the principles of Synthetic Urbanism to transform Tehran into a playable co-creation space. While digital twin solutions and citizen-driven spatial planning ideas have both evolved independently, their integration as a pragmatic tool for stakeholder engagement through high-fidelity synthetic models is novel. By combining digital twin models and VR and AR models infused with game design principles, this suggested solution engages citizens, spatial planners, and political leaders alike for the collaborative design of spatial solutions for Tehran. The significance of this synthesis, according to this research, is that it fills a pressing gap in the current state of spatial planning for complex cities such as Tehran.

德黑兰正在努力应对一系列独特的城市化挑战，这些挑战需要超越传统的自上而下的空间规划的创新空间规划实践。这个简短的交流提出了一个新的综合概念：将游戏化的共同创造与综合城市主义的原则相结合，将德黑兰转变为一个可玩的共同创造空间。虽然数字孪生解决方案和公民驱动的空间规划理念都是独立发展的，但它们通过高保真综合模型作为利益相关者参与的实用工具的整合是新颖的。通过结合数字孪生模型和融入游戏设计原则的VR和AR模型，这个建议的解决方案吸引了市民、空间规划者和政治领导人，共同设计德黑兰的空间解决方案。根据这项研究，这种综合的意义在于，它填补了德黑兰等复杂城市空间规划现状中的一个紧迫空白。

Rapid urbanisation in African cities is intensifying solid waste challenges, especially in informal settlements where uneven services and socio-spatial heterogeneity complicate planning. This study quantifies the socio-spatial determinants of household solid waste generation in Mbagala Kuu Ward, a peri-urban informal settlement in Dar es Salaam, Tanzania, and translates results into an operational targeting tool for municipal decision-making. Household survey data (n = 115) were integrated with GIS-derived indicators of land use, population density and service accessibility and analysed using a Spatial Lag Gamma Generalised Linear Model with Moran’s Eigenvector Filtering to capture neighbourhood spillovers. Households generated an average of 5.94 kg day⁻1 (SD = 3.18), equivalent to 1.40 kg capita⁻1 day⁻1, of which only 47% was formally collected. Waste generation was spatially clustered (Moran’s I = 0.257, p < 0.001) and the spatial lag effect was positive (ρ = 0.241), indicating significant neighbourhood dependence. Higher education and income were associated with higher recorded waste, while greater distance to collection points was associated with reduced formal disposal (approximately 11% per additional 100 m). Commercial areas generated > 5 × more waste than residential areas, whereas urban agriculture and open spaces generated 40–––50% less. The model showed strong predictive performance (Pseudo-R2 = 0.79; MAE = 1.13 kg). To move from analysis to action, a Targeting Ratio assessment indicates that the highest-burden 20% of neighbourhood zones account for approximately 65% of total predicted waste, providing a practical basis for prioritising collection-point siting, routing and service frequency under constrained municipal resources. The findings support a shift from uniform service provision to neighbourhood-targeted waste planning, where infrastructure placement and collection schedules are aligned with spatially concentrated waste burdens and access constraints.

非洲城市的快速城市化加剧了固体废物的挑战，特别是在服务不均衡和社会空间异质性使规划复杂化的非正式住区。本研究量化了坦桑尼亚达累斯萨拉姆城市周边非正式住区姆巴加拉库乌区家庭固体废物产生的社会空间决定因素，并将结果转化为市政决策的业务目标工具。将住户调查数据（n = 115）与gis衍生的土地利用、人口密度和服务可及性指标相结合，并使用带有Moran特征向量滤波的空间滞后伽玛广义线性模型进行分析，以捕捉邻里溢出效应。家庭平均每天产生5.94公斤的毒血症（SD = 3.18），相当于每人每天产生1.40公斤的毒血症，其中只有47%被正式收集。废弃物产生具有空间聚集性（Moran’s I = 0.257, p < 0.001），空间滞后效应为正（ρ = 0.241），表明存在显著的邻域依赖性。教育程度和收入越高，记录在案的废物越多，而距离收集点越远，正式废物处理量就越少（每增加100米，大约减少11%）。商业区产生的废物比住宅区多5倍，而城市农业和开放空间产生的废物比住宅区少40 - 50%。该模型具有较强的预测性能（伪r2 = 0.79; MAE = 1.13 kg）。从分析到行动，目标比率评估表明，负担最重的20%街区约占预计废物总量的65%，这为在市政资源有限的情况下确定收集点选址、路线和服务频率的优先顺序提供了实际依据。研究结果支持从统一的服务提供转向以社区为目标的废物规划，其中基础设施的放置和收集时间表与空间集中的废物负担和获取限制保持一致。
