Due to the continuous increase in global energy demand,photovoltaic solar energy generation and associated maintenance requirements have significantly expanded.One critical maintenance challenge in photovoltaic installations is detecting hot spots,localized overheating defects in solar cells that drastically reduce efficiency and can lead to permanent damage.Traditional methods for detecting these defects rely on manual inspections using thermal imaging,which are costly,labor-intensive,and impractical for large-scale installations.This research introduces an automated hybrid system based on two specialized convolutional neural networks deployed in a cascaded architecture.The first convolutional neural network efficiently detects and isolates individual solar panels from high-resolution aerial thermal images captured by drones.Subsequently,a second,more advanced convolutional neural network accurately classifies each isolated panel as either defective or healthy,effectively distinguishing genuine thermal anomalies from false positives caused by reflections or glare.Experimental validation on a real-world dataset comprising thousands of thermal images yielded exceptional accuracy,significantly reducing inspection time,costs,and the likelihood of false defect detections.This proposed system enhances the reliability and efficiency of photovoltaic plant inspections,thus contributing to improved operational performance and economic viability. 展开更多

Human pressure on mountain resources poses certain threats to their natural and man-made environment. Although there are many parameters involved, one of the driving forces behind this situation is the emphasis given so far only to the market value of mountain goods and services, ignoring the true social and environmental costs of using mountain resources. Towards this direction, the use of non-market valuation techniques could prove to be beneficial. Bearing in mind the above remarks, the paper presents an application of the Contingent Valuation Method, which aims at estimating the monetary value of a mountain settlement’s vernacular architecture, namely Metsovo. For this purpose, the survey focuses on Metsovo visitors’ willingness to pay a single annual voluntary contribution to an institution that would be founded in order to undertake all necessary actions required to preserve the town’s traditional character. The results are very promising and indicate that vernacular architecture holds a significant economic value that could justify the implementation of appropriate policies towards the protection of vernacular settlements in mountain areas. 展开更多

In order to study the engineering behaviors of reinforced gabion retaining wall,laboratory model test was carried out.Cyclic load and unload of five levels(0-50,0-100,0-50,0-200 and 0-250 kPa) were imposed.Vertical earth pressure,lateral earth pressure,deformation behaviors of reinforcements,potential failure surface and deformation behaviors of wall face were studied.Results show that vertical earth pressure is less than theoretical value,the ratio of vertical earth pressure to theoretical value increases nearly linearly with increasing load,and the correlation coefficient of regression equation is 0.92 for the second layer and 0.79 for the fifth layer.The distribution of lateral earth pressure along the wall back is nonlinear and it is less than theoretical value especially when the load imposed at the top of retaining wall is large.Therefore,reinforced gabion retaining wall will be in great safety when current method is adopted.The deformation behaviors of reinforcements both in the third layer and the fifth layer are single-peak distributions,and the position of the maximum strain is behind that determined by 0.3H(Here H refers to the height of retaining wall) method or Rankine theory.Lateral deformation of wall face increases with increasing load,and the largest lateral deformation occurs in the fourth layer,which lead to a bulging in the middle of wall face. 展开更多

In megacities, the phenomenon of the highrise buildings which add fashion elements into the body and facades seems as big sculptures. Architect composed their work by applying the cross-pollination of design method. They adopted the various elements to enrich their building's facade in order to look different. On the other hand, the traditional architecture expressed the tribe civilization by placing their proud artifacts into the building's facade. The purpose of this study is to find a new theory of architecture during their process of becoming of the architecture's form. The study applied a phenomenological investigation method of several highrise building's facade at Jakarta and several districts of Singapore, Brisbane and Melbourne. The study result is a new theory named "the fashion-architecture" is a building composed by adopting the cross-pollination of design method. To enrich the building's facade, architect adopted anything including the fashion's design elements: accessories, millineries, and cosmetics also reflected by the traditional architecture. Their fashion-architecture works are reflecting the tribe civilization into a contemporary architecture design. 展开更多

With the continuous development of today's construction industry, the construction of underground engineering is becoming more and more common. Especially with the accelerating process of urbanization, more and more construction projects and underground projects begin to develop in the direction of ultra-deep and multi-layered. However, under the influence of groundwater, the underground building engineering structure will be subject to greater buoyancy, and this buoyancy will increase with the buried depth of the underground building structure, which will lead to the floating of the bottom plate and wall. In serious cases, there will even be building overturning, which will bring a great security threat to the construction engineering. In order to ensure the anti- floating ability of underground engineering, the anti-floating design and control measures are analyzed in this paper. It is hoped that this analysis can lay a good foundation for the improvement of anti-floating performance of underground construction engineering, so as to ensure the quality and safety of the overall construction engineering. 展开更多

In the process of continuous development of society, great changes have taken place in people's lives, and higher requirements have been put forward for their work and living environment, which has promoted the development of architectural decoration industry. In the process of building decoration, decoration companies should realize the importance of project management, reasonably choose construction technology, and ensure the construction quality on the basis of improving the management level. Project management and construction technology can be directly related to the development of the decoration company. Therefore, it is necessary to further strengthen management, introduce advanced management concepts and technologies, and adopt less advanced technologies to ensure that the personnel involved in construction can fully grasp the skills of the use of construction technology, and give full play to its role, so as to optimize the management efficiency and construction level of building decoration engineering, and promote the development of building decoration industry. 展开更多

Approximately 3.44 billion tons of copper mine tailings(MT)were produced globally in 2018 with an increase of 45%from 2010.Significant efforts are being made to manage these tailings through storage facilities,recycling,and reuse in different industries.Currently,a large portion of tailings are managed through the tailing storage facilities(TSF)where these tailings undergo hydro-thermal-mechanical stresses with seasonal cycles which are not comprehensively understood.This study presents an investigative study to evaluate the performance of control and cement-stabilized copper MT under the influence of seasonal cycles,freeze-thaw(F-T)and wet-dry(W-D)conditions,representing the seasonal variability in the cold and arid regions.The control and cement-stabilized MT samples were subjected to a maximum of 12 F-T and 12 W-D cycles and corresponding micro-and-macro behavior was investigated through scanning electron microscope(SEM),volumetric strain(εvT,wet density(r),moisture content loss,and unconfined compressive strength(UCS)tests.The results indicated the vulnerability of Copper MT to 67%and 75%strength loss reaching residual states with 12 F-T and 8 W-D cycles,respectively.Whereas the stabilized MT retained 39%-55%and 16%-34%strength with F-T and W-D cycles,demonstrating increased durability.This research highlights the impact of seasonal cycles and corresponding strength-deformation characteristics of control and stabilized Copper MT in cold and arid regions. 展开更多
