Performance evaluation and degradation analysis of 20 MW photovoltaic power plant located in the southwestern highlands of Algeria

This article evaluates the performance of a 20 MW grid-connected photovoltaic system installed in the Naama region, southwestern highlands of Algeria. The production database used in this work was recorded between January 1, 2017, and December 2022, from the plant’s SCADA system. During the first 5 years of production, the final yield varied from 3.88 in winter 2020 to 6.30 h/day in summer 2017, while the reference yield varied from 4.45 to 7.05 h/day, the annual average performance ratio is equal to 83.35%, and the annual average capacity factor was found to be 20.05% for the monitored period. These data are then compared with the predicted outcomes by a detailed difference analysis using three widely used PV simulation tools: PVsyst, SAM, and PVSol. Results indicate that the actual data strongly coincide with those predicted by the PVsyst simulation, as confirmed by statistical indices. However, the degradation of the PV plants over the monitored period is quantified using a linear model and a CSD model and is estimated at −1.43 and −1.55 %/year, respectively. In summary, the photovoltaic system performance indices obtained are satisfactory compared to large-scale photovoltaic systems reported in other studies. Practical applications This study evaluates the performance and degradation of a 20 MWp photovoltaic system located in the highlands of Algeria. The results of this article will serve as a baseline for the future construction of PV plants to raise awareness among decision-makers about the beginnings of the deterioration of installations to allocate a budget for the maintenance and operation of these installations. The findings of this study have the potential to contribute to the wider adoption of Photovoltaic systems as a viable alternative to traditional energy in Algeria and especially in the Highlands.

Application and Benefit Assessment of Sustainable Building Materials in High-Rise Building Design

With increasing environmental awareness, the use of sustainable building materials in modern high-rise architecture has become increasingly prominent. This paper provides a detailed analysis of Wood Chip Concrete Blocks (CBWC), exploring their application in high-rise building design, along with their environmental attributes, thermal performance, and structural integrity. Research indicates that CBWCs have a thermal resistance of R=5.26 m²K/W and fire resistance exceeding 180 minutes, significantly enhancing the building's energy efficiency and environmental friendliness. Simulation data reveals that the improved CBWC2 model, after partial filling and reinforcement, increased its peak horizontal force to 165.2 kN and reduced displacement to 9.99 mm, indicating enhanced structural stability. This study aims to use wood chip-reinforced concrete blocks to improve building energy efficiency and reduce carbon footprint while ensuring durability and safety, providing a sustainable material choice for future constructions.

Combining Building Information Model and Life Cycle Assessment for Defining Circular Economy Strategies

Although the construction industry has the potential to implement circular economy (CE) principles, the sector suffers from a veritable lack of initiatives to develop circular and regenerative design principles. However, existing buildings intended to be demolished could be considered as material banks for future constructions, with the aim to exploit anthropogenic resources, extend material/product efficiency, and reduce the extraction of natural resources. This concept of buildings as material banks is being studied more and more in the scientific literature, but it still requires the existing building stock to be fully digitalized, thus making materials reusable in new buildings starting from the architectural design stage. Moreover, the decision process regarding CE strategies requires the consideration of the environmental impacts of the deconstruction and end-of-life processes, which is essential in CE implementation. This paper introduces a digital platform for generating materials inventory and supporting the definition of reuse strategies. Then, by using digital tools in combination with life cycle assessment (LCA) studies of the deconstruction process and output of materials and components inventories, a method is defined and tested on a pilot building in Luxembourg.

Laboratory studies on the mechanical properties of sulphur-based construction material at simulated Martian temperatures

Mars is the next destination for further exploration and the hypothetical establishment of humanity's frontier. However, the planet offers very harsh environmental conditions particularly the very cold temperature in the Martian environment. Knowing that the sulphur-based construction material is perceived as one of the ideal Martian construction materials based on the identified abundant source of sulphur on Mars, its behaviour when subjected to the very cold Martian temperature is yet to be fully clarified. Therefore, this study intends to investigate the behaviour of the Martian sulphur-based construction material subjected to the simulated very cold Martian temperature whilst being compared with the simulated hot Martian temperature. Two mixture compositions of 50/50 and 60/40 comprising of sulphur and Mojave Mars simulant 1 (MMS-1) respectively were fabricated in this study characterising the simulated Martian temperature. The workability at 50 % and 60 % sulphur content was initially investigated. Subsequently, the overall mechanical properties characterising the sulphur content and simulated Martian temperature were investigated via unconfined compression, three-point bending and tensile splitting tests. Necessary factors that influence the overall mechanical properties including the internal structure and microstructural characteristics were also performed via ultrasonic pulse velocity (UPV) and scanning electron microscopy (SEM) respectively. X-ray diffraction (XRD) was also conducted to identify the chemical composition of the end product. The comparisons between this study and other previous related studies within the state-of-the-art Martian sulphur-based construction materials were also outlined. Prospects for future construction on Mars are also presented. It was found that the 60 % sulphur content exhibited higher workability due to the high amount of unreactive sulphur. The 50 % sulphur content recorded the optimal overall mechanical properties under the simulated hot and very cold Martian temperatures. The simulated very cold Martian temperature triggered non-uniform interparticle distribution and larger cavities thus dramatically reducing its overall strength and triggering higher volumetric inconsistency. The very brittle nature of unreactive crystallised sulphur binder at excessive thickness particularly at 60 % sulphur content in between filler particles also triggered volumetric inconsistency which further worsened at the simulated very cold Martian temperature. The iron sulphate hydrate found was almost in agreement with the related works and another new compound, potassium calcium magnesium sulphate was identified as well. The overall mechanical properties are comparable with the other previous related studies and the residual strength when subjected to the simulated very cold Martian temperature remains adequate in the Martian environment of low gravity. The 60 % sulphur content is suggested for structural elements built internally whereas the 50 % sulphur content demonstrated a high potential in adapting to the harsh Martian environmental conditions. The findings of this study hoped to act as the initial outlook on how such Martian sulphur-based construction material would react upon fabrication on Mars.

RGBT tracking: A comprehensive review

In recent years, visual object tracking, as a prominent research area in computer vision, has garnered significant attention. To bolster the robustness of trackers across a spectrum of complex scenarios, researchers actively explore the synergistic potential of visible and thermal infrared images, aiming to design more potent tracking systems. This paper presents a comprehensive review of target tracking technology based on visible and thermal infrared information, encompassing three key aspects. Firstly, we categorize existing RGBT tracking methods into two main categories: traditional-based methods and deep learning-based methods. This classification facilitates a systematic understanding and comparison of the strengths and weaknesses of different approaches, providing a solid foundation for future research. Secondly, we focus on the evolution of RGBT datasets and analyze the performance of diverse tracking methods on these datasets. Research in this domain aids in evaluating the applicability of existing methods in real-world scenarios and offers guidance for future dataset construction. Finally, we delve into future research directions from multiple perspectives, including model design and dataset construction. In terms of model design, researchers are encouraged to explore more efficient feature extraction methods and innovative model fusion structures to further enhance tracker performance. Regarding dataset construction, increased attention should be given to ensure diversity in real-world scenarios, guaranteeing optimal tracker performance across a variety of complex conditions. In conclusion, this review makes a comprehensive analysis of the development of RGBT tracking from different perspectives, and provides a valuable reference for researchers in related fields such as multi-modal tracking and image fusion. By systematically classifying and analyzing existing research while outlining future research prospects, this review aims to foster the continued development of this field and inspire the emergence of more innovative work.

Cumulative Effects of Watershed Disturbances and Run-of-river Dams on Mercury Cycling: Case Study and Recommendations for Environmental Managers.

Run-of-river power plants (ROR) represent the majority of hydroelectric plants worldwide. Their environmental impacts are not well documented and are believed to be limited, particularly regarding the contamination of food webs by methylmercury (MeHg), a neurotoxin. RORs are typically installed in small rivers where combined effects of watershed disturbances with dam construction can complicate environmental management. We report a multi-year case study on the Saint-Maurice River (Canada) where an unpredicted temporary increase in MeHg accumulation in predator fish was observed after the construction of two ROR plants. The associated pondages acted as sedimentation basins for mercury (Hg) and organic matter from a watershed disturbed by a forest fire and by logging. This fresh organic carbon likely fueled microbial MeHg production. Hg methylation was more associated with environmental conditions than to the presence of Hg, and main methylating microbial groups were identified. A constructed wetland was a site of significant Hg methylation but was not the main source of the fish Hg increase. Organic carbon degradation was the main driver of MeHg accumulation at the base of the food chain whereas trophic levels explained the variations at the top of the food chain. Overall, carbon cycling was a key driver of Hg dynamics in this system, and ROR plants can cause temporary (ca. 12 years) Hg increase in food webs when developed in disturbed watersheds, although this increase is smaller than for large reservoirs. Recommendations for future ROR construction are to establish a good environmental monitoring plan with initial high temporal resolution and to consider recent and potential watershed disturbances in the plan.

The impact of radio on the construction of smart cities

In the process of smart cities, radio technology has played an increasingly important role. With the continuous acceleration of the global urbanization process, cities are facing many challenges. Driven by the governments vigorous support and business promotion, wireless communication technology has developed rapidly, and new wireless communication technology has continued to emerge, providing more choices and possibilities for smart city construction. This article reviews and analyzes the actual case analysis, studies the impact of radio technology on the construction of smart cities, while explaining the importance of radio security management. The results showed that the application of radio technology enabled smart cities to achieve functions such as intelligent traffic management, intelligent communication, and intelligent energy management, but there were also problems such as leakage privacy, signal interference, and imbalance in regional development. In the process of future smart city construction, it is necessary to further optimize the safety and popularity of radio, promote the use of radio, narrow the gap between the use of different regions and cities, and enhance the radio management, so that it can better serve the construction of smart cities.

Design and construction of small-scaled variable modular installation (SVMI) in the context of Chinese street renewal (CSR) : A case study of the "Jingzhang Box" (JZB) service installation in Beijing

China's urban areas are entering an era of stock renewal, where street renewal is receiving policy attention and practical project implementation. However, the challenges posed by spatial constraints and insufficient functional activities on the streets have led to street renewal failing to meet public demands. Small Variable Modular Installations (SVMI) possess a high degree of adaptability to constrained spaces and a flexible capacity to shape diverse functions, making them a targeted strategy in theory to address the challenges of street renewal. Nevertheless, there is a research gap in the context of Chinese street renewal (CSR) concerning the design, and construction of SVMI: an insufficient exploration of combined variable and modular technology solutions and practical construction techniques and methods. In response to this research gap, this study focuses on the "Jing-Zhang Box" (JZB) service installation in Beijing, providing specific analysis of its design concept, design technical points, application functions, spatial structure and connection methods, construction methods, and construction outcomes. This study aims to provide specific supplementation to the research on SVMI design and construction in the context of CSR and to offer theoretical and engineering foundations for the future design and practical construction of SVMI in various scenarios.

Analisis Penerapan Metode HIRARC Untuk Meningkatkan Keselamatan Dan Kesehatan Kerja Pada Konstruksi Saluran Kabel Tegangan Menengah (SKTM)

Electricity is a vital aspect of modern infrastructure that supports various human activities. Therefore, the increasing need for electrical energy requires good planning to ensure the availability of electrical energy in the future. The transmission system, especially the Medium Voltage Cable Line (MVCL), plays an important role in distributing electrical energy from generators to consumers. However, MVCL construction involves high-risk work, so it requires special attention to occupational health and safety (OHS). This research uses the HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method to identify and control risks in MVCL construction projects. It is hoped that the results of this research can provide recommendations for improving occupational safety and health as well as efficiency in future MVCL construction projects.

Systematic metabolic engineering of Zymomonas mobilis for β-farnesene production.

Zymomonas mobilis is an ethanologenic bacterium that can produce hopanoids using farnesyl pyrophosphate (FPP), which can be used as the precursor by β-farnesene synthase for β-farnesene production. To explore the possibility and bottlenecks of developing Z. mobilis for β-farnesene production, five heterologous β-farnesene synthases were selected and screened, and AaBFS from Artemisia annua had the highest β-farnesene titer. Recombinant strains with AaBFS driven by the strong constitutive promoter Pgap (Pgap-AaBFS) doubled its β-farnesene production to 25.73 ± 0.31mg/L compared to the recombinant strain with AaBFS driven by Ptet (Ptet-AaBFS), which can be further improved by overexpressing the Pgap-AaBFS construct using the strategies of multiple plasmids (41.00 ± 0.40mg/L) or genomic multi-locus integration (48.33 ± 3.40mg/L). The effect of cofactor NADPH balancing on β-farnesene production was also investigated, which can be improved only in zwf-overexpressing strains but not in ppnK-overexpressing strains, indicating that cofactor balancing is important and sophisticated. Furthermore, the β-farnesene titer was improved to 73.30 ± 0.71mg/L by overexpressing dxs, ispG, and ispH. Finally, the β-farnesene production was increased to 159.70 ± 7.21mg/L by fermentation optimization, including the C/N ratio, flask working volume, and medium/dodecane ratio, which was nearly 13-fold improved from the parental strain. This work thus not only generated a recombinant β-farnesene production Z. mobilis strain but also unraveled the bottlenecks to engineer Z. mobilis for farnesene production, which will help guide the future rational design and construction of cell factories for terpenoid production in non-model industrial microorganisms.

The Effect of Green Stormwater Infrastructures on Urban-Tier Human Thermal Comfort—A Case Study in High-Density Urban Blocks

Green stormwater infrastructure (GSI) is a key approach to greening and cooling high-density blocks. Previous studies have focused on the impact of a single GSI on thermal comfort on sunny days, ignoring rainwater’s role and GSI combinations. Therefore, based on measured data of a real urban area in Nanjing, China, this study utilized 45 single-GSI and combination simulation scenarios, as well as three local climate zone (LCZ) baseline scenarios to compare and analyze three high-density blocks within the city. Among the 32 simulations specifically conducted in LCZ1 and LCZ2, 2 of them were dedicated to baseline scenario simulations, whereas the remaining 30 simulations were evenly distributed across LCZ1 and LCZ2, with 15 simulations allocated to each zone. The physiological equivalent temperature (PET) was calculated using the ENVI-met specification to evaluate outdoor thermal comfort. The objective of this research was to determine the optimal GSI combinations for different LCZs, their impact on pedestrian thermal comfort, GSI response to rainwater, and the effect of GSI on pedestrian recreation areas. Results showed that GSI combinations are crucial for improving thermal comfort in compact high-rise and mid-rise areas, while a single GSI suffices in low-rise areas. In extreme heat, rainfall is vital for GSI’s effectiveness, and complex GSI can extend the thermal comfort improvement time following rainfall by more than 1 h. Adding shading and trees to GSI combinations maximizes thermal comfort in potential crowd activity areas, achieving up to 54.23% improvement. Future GSI construction in high-density blocks should focus on different combinations of GSI based on different LCZs, offering insights for GSI planning in Southeast Asia.

Mechanical characteristics of hoisting construction of segmental cantilever assembled box girder bridge

Abstract In order to study the safety of the segmental box girder in the hoisting process, this paper designed the construction method of the gantry crane hoisting segmental box girder in combination with the actual project. By establishing a mathematical model, the mechanical properties of the segmental box girder under two different hoisting schemes were analyzed. Under different load conditions, the lifting analyses, translation analyses and descending analyses of the box girder were carried out respectively, and the deflection and stress corresponding to the box girder were obtained. Considering the displacement and stress results of the box girder under the two hoisting schemes, it was concluded that the hoisting construction of the segmental box girder should give priority to the second hoisting scheme. That is, the hoisting holes were opened at the flange position of the roof. Provide feasible technical support for future construction.

Study on the Expansion Potential of Artificial Oases in Xinjiang by Coupling Geomorphic Features and Hierarchical Clustering

The study of the expansion potential of artificial oases based on remote sensing data is of great significance for the rational allocation of water resources and urban planning in arid areas. Based on the spatio-temporal relationship between morphogenetic landform types and the development of artificial oases in Xinjiang, this study explored the development pattern of artificial oases in the past 30 years by using trend analysis and centroid migration analysis, constructing a series of landform–artificial oasis change indices, and investigating the suitability of different landforms for the development of artificial oases based on geomorphological location by adopting a hierarchical clustering method. The following conclusions are drawn: (1) From 1990 to 2020, the area of artificial oases in the whole territory continued to increase, with significant expansion to the south from 2005 to 2010. (2) Six categories of landform types for artificial oasis development were created based on the clustering results. Of these, 7.39% and 6.15% of the area’s geomorphological types belonged to the first and second suitability classes, respectively. (3) The optimal scale for analyzing the suitability of landforms for the development of artificial oases over the past 30 years in the whole area was 8 km, which could explain more than 96% of the changes in the growth of artificial oases. The distribution of landforms of first- and second-class suitability within the 8 km buffer zone of an artificial oasis in the year 2020 was 10.55% and 9.90%, respectively, and landforms of first-class suitability were mainly concentrated in the near plain side of the urban agglomerations located on the northern and southern slopes of the Tianshan Mountains, and the urban agglomerations at the southern edge of Altai Mountains. This study quantified the potential of different geomorphological types for the development of artificial oases and provided a basis for site selection in future artificial oasis planning and urban construction.

Cultural communication in museums: A perspective of the visitors experience

As museums shift their responsibilities and functions towards audience-centered approaches, research on exploring museum cultural communication strategies through visitor experiences has gained increasing attention from both academia and industry. This study focuses on the newly opened Nan Song Deshou Palace Relics Site Museum in Hangzhou, China, completed at the end of 2022, and its visitors. Data were collected through on-site surveys and in-depth interviews. The research findings indicate that the current motivations of museum visitors manifest primarily in three forms: knowledge exploration, social interaction, and psychological restoration. After evaluating the existing museum service quality based on the field of experiential value in marketing management, two main issues and features were identified. The issues include sub-optimal visitor pathways and layout, dissatisfaction with staff services, and shortcomings in promotion and communication. The overall cultural learning and interactive experience for the entire visitor base also require improvement. The features are characterized by differentiated cultural and creative consumption in the museum and the emergence of interrelated consumer demands. Based on these findings, the study provides targeted recommendations for future museum construction and communication strategies.

An assessment of urban park accessibility using multi‐source data in Hefei, China: A social equity perspective

AbstractUrban parks are vital to enhance human well‐being and encourage sustainable urban development. However, the supply–demand match between the layout of urban parks and various social groups needs to be addressed. Therefore, this study quantitatively evaluates urban park accessibility using house‐level data from the social equity perspective in Hefei, China. A real‐time navigation route measurement based on the Amap application programming interface was taken advantage of to calculate green space travel time costs‐accessibility, and a combination of the Gaussian‐based two‐step floating catchment area method and measurement model to analyze supply–demand accessibility. On the other hand, housing price was used to indicate dwellers' socioeconomic status. The Gini coefficient, Lorenz curve, and bivariate correlation were adopted to explore the inequality of green space accessibility among residential communities. The results reveal a spatial inequality of green space between communities in the central portion of the Hefei and those in peri‐urban areas. We further found a spatial mismatch between green space resources and population distribution. At the same time, there is a significant correlation between green space accessibility and housing prices, which means the disadvantaged urban strata with low economic income face a supply shortage, while wealthier communities benefit more from green space accessibility. Hence, based on the evaluation results, the author proposes feasible optimization strategies for constructing urban parks in Hefei and can inform policy decisions regarding future park construction.

Optimization Study on Key Technology of Improved Arch Cover Method Construction for Underground Metro Stations Based on Similar Model Test

To enhance comprehension of the improved arch cover construction method for underground metro stations and provide guidance for future construction techniques and programs, the paper examines the indoor improved arch cover method of construction in the underground concealed excavation station of Tianhe Road Station of Guangzhou Metro Line 10, China. It includes a similar model test of the key technology and an analysis of the evolution law of the surrounding rock stress, the law of the ground settlement, and the law of the arch top deformation after the tunnel excavation. The study found that increased over-support can decrease arch settlement, with the maximum settlement occurring near the arch. Ground settlement typically occurs in the same areas as arch settlement, but arch settlement may occur earlier. The excavation of the arch cover has little impact on the overlying soil pressure, and the supporting structure is more effective in controlling soil deformation. The upper part of the arch cap experiences mainly extrusion stress, with the maximum stress occurring near the middle of the arch. The stresses in the arch’s base decrease significantly during the excavation of the side drifts but show an increasing trend during the excavation of the lower rock mass. The presence of the central column significantly affects both the settlement of the arch and the ground, as it bears most of the compressive stress of the arch. This stress decreases initially and then increases. The amplitude of deformation is more pronounced when the dismantled central column is closer to the middle of the arch.

Introducing a Novel Concept for an Integrated Demolition Waste Recycling Center and the Establishment of a Stakeholder Network: A Case Study from Germany

Using recycled aggregates has many positive environmental impacts because of the conservation of natural resources and minimization of waste. The use of recycled aggregates in downcycling processes is already common in Germany, whereas utilizing them to produce high-quality recycled concrete is rarely applied in practice. The reasons behind this lag have been investigated based on surveys and interviews with stakeholders. Miscommunication and missing information were identified in all stakeholder groups. Therefore, establishing a robust network and facilitating knowledge transfer by specifying the demand for recycled aggregates in the case study region have been considered as prerequisites. Therefore, the paper presents a novel concept of a stakeholder network for an integrated construction and demolition waste center. The conceptualization integrates the recycling companies and construction product manufacturers in one venue with research, service, and educational divisions. The design of the facilities is based on calculations regarding future construction activities and the demand for concrete production. The proposed concept aims to supply the region in the west of Germany with high-quality recycled products while also establishing a robust network that offers benefits in terms of logistical optimization and knowledge transfer.

Frictional Behavior of Chestnut (Castanea sativa Mill.) Sawn Timber for Carpentry and Mechanical Joints in Service Class 2

Wood is poised to become a material of choice for future construction. When appropriately managed, it is a renewable material with unique mechanical properties. Thus, there has been a growing demand for hardwoods, including Castanea sativa Mill., the focal point of this investigation, for structural applications. Albeit in a limited capacity, Eurocode 5-2 offers friction coefficients for softwoods, but it falls short for hardwoods. These coefficients play a critical role in numerical simulations involving friction, enabling the optimization of joints and, by extension, the overall structural integrity. Test samples were evaluated at 15% and 18% moisture content (Service Class 2) for various orientations of timber-to-timber and timber-to-steel friction. The results provide an experimental database for numerical simulations and highlight the influence of moisture on the stick–slip phenomenon, which was absent for the timber-to-timber tests, as well as on the rising friction values. At 18%, the static and kinetic coefficients were 0.70 and 0.48 for timber-to-timber and 0.5 and 0.50 for timber-to-steel. The increase was around 50% for timber-to-timber friction and over 170% for timber-to-steel pairs. Moreover, the findings proved a relationship between both coefficients and the validity of the linear estimation approach within the 12–18% moisture commonly applied to softwoods.

Reflections on the Application of Digital Design in Future Urban Construction

As globalization deepens, it brings new opportunities for urban construction. With the acceleration of urban planning processes and the pressures of population growth, higher demands are placed on urban construction. At the same time, rapid developments in science and technology provide new ideas and directions for urban construction. Digital design, as an emerging design concept and technical method, is becoming an important support for future urban construction. By utilizing advanced technologies such as big data, cloud computing, and artificial intelligence, digital design can achieve comprehensive optimization of urban planning, architectural design and construction, and urban management and services, bringing revolutionary changes to urban construction. Therefore, this paper explains the technological basis of digital design in current urban construction to provide a background for understanding its application. It then delves into the specific application advantages of digital design in three aspects: urban planning, architectural design and construction, and urban management and services. However, digital design still faces multiple challenges in application, such as technology, security, and privacy issues, which need to be addressed through corresponding strategies. Through in-depth research and practice, it is believed that digital design will bring more sustainable solutions to future urban construction.
