摘要：
A city is an organic system. It is necessary to correctly handle the valuable historic buildings and blocks to promote the sustainable development of the city, because they are non-renewable resources in urban development. This paper takes the renovation project of Wuhan Art Museum as the research object. It explored the general methods of the protection and renewal of historic buildings from the aspects of historical value, appearance design, functional layout, etc. This research used the method of combining theory with practice and summarized the key points of the renovation of historic buildings by case analysis. The purpose of this research is to find a way to reuse historic buildings in line with China's national conditions. This can provide a useful reference for other similar projects. The practice of the renovation project must be given appropriate uses, which is the key to continue their lives. Only in this way can old buildings meet the modern lifestyle.

摘要：
This paper takes solar-powered organic Rankine-vapor compression air conditioning as the research object, and uses thermodynamic simulation methods to study the type of working fluid, system design and influencing factors. The results show that the temperature and condensation temperature of the working fluid have an important effect on the performance of the system. The cooling power per unit area collector and the total efficiency of the system first increase and then decrease with the temperature of the working fluid, and decrease with the increase of the condensation temperature. Through performance comparison, it is found that R123 is a more suitable working fluid, the thermodynamic feasibility of a solar-powered organic Rankine-vapor compression air-conditioning system was demonstrated.

摘要：
With the development of BIM(Building Information Modeling) technology, CIM(City Information Modeling) is accompanied by the development of Internet of Things technology, and the development of CIM has become an academic hotspot. In recent years, due to the limitations of BIM and CAD, it is impossible to transform the spatial and temporal relationship information well. Therefore, the emergence of CIM represents the progress of the construction industry, especially the integration of BIM and CIM makes it complementary, which can maximize the construction of smart cities.

摘要：
Federated Learning (FL) offers a novel distributed machine learning context whereby a global model is collaboratively learned through edge devices without violating data privacy. However, intrinsic data heterogeneity in the federated network can induce model heterogeneity, thus posing a great challenge to the server-side model aggregation performance. Existing FL algorithms widely adopt model-wise weighted averaging for client models to generate the new global model, which emphasizes the importance of the holistic model but ignores the importance of distinctions between internal parameters of various client models. In this paper, we propose a novel parameter-wise elastic weighted averaging aggregation approach to realize the rapid fusion of heterogeneous client models. Specifically, each client evaluates the importance of model internal parameters in the model update and obtains the corresponding parameter importance coefficient vector; the server implements the parameter-wise weighted averaging for each parameter based on their importance coefficient vectors, thereby aggregating a new global model. Extensive experiments on MNIST and CIFAR-10 datasets with diverse network architectures and hyper-parameter combinations show that our proposed algorithm outperforms the existing state-of-the-art FL algorithms on the performance of heterogeneous model fusion.

摘要：
In this paper, for the low-temperature geothermal organic Rankine (ORC) power generation system, the subcritical saturated vapor cycle is selected as the key research object, the mathematical and physical model of the thermal process of the ORC system is established, and five organic working fluids are selected. With the net power produced per unit mass of geothermal water(PPH) as the optimization target, the optimal parameters of the ORC system are determined. Based on the selection of the best organic working fluid, various parameters that affect the performance and economic performance of the ORC system are analyzed. After simulation calculation, the results show that: when the system takes PPH as the optimization target, the working fluid R245fa can be selected as the best applicable working fluid.

摘要：
The horizontal tube spray falling film evaporator is an efficient evaporation equipment, which has the advantages of good heat exchange effect, small equipment volume and low cost. In this paper, R245fa is used as the working fluid to build a heat transfer test platform for the horizontal pipe spray falling film evaporator of the Organic Rankine Cycle(ORC) power generation system. The effect of factors such as the spray density of the organic working fluid, the initial temperature of the geothermal water and the flow on the heat transfer coefficient outside the tube is studied. The experimental results show that with the increase of the spray density of the organic working fluid, the initial temperature of the geothermal water, and the flow of the geothermal water, the heat transfer coefficient first increases and then decreases.

摘要：
In order to effectively use the waste heat of ship flue gas and cooling water, in this paper, the organic Rankine-vapor compression refrigeration system is used for air conditioning for ships, and the thermodynamic model of the system is established. The system performance corresponding to the five commonly used working fluids R22, R141b, R236ea, R218 and R601 is analyzed and compared. The working fluid is optimized with the goal of the best system performance. Calculations proves that: regardless of the organic Rankine cycle and vapor compression refrigeration cycle, or for the entire system, R601 is the most suitable working fluid. The temperature of the heat source and the condensing temperature have an important effect on the performance of the system. The hot water temperature can be controlled and adjusted by changing the hot water flow rate, thereby optimizing system performance. At the same time, the determination of the condensing temperature should comprehensively consider the system performance, cooling water pump power, heat exchanger area and system investment to achieve the best overall system performance.

摘要：
Residential project is an important component of sponge city construction management, and its performance has a significant impact on the disaster resilience and sustainable development of cities. This paper constructed a novel evaluation model based on the interval analytic hierarchy process and the improved TOPSIS. On the basis of consulting norms and literature research, performance evaluation indicators from the aspects of ecological benefits, economic benefits, and social effects were proposed. To accurately describe the preference and experience of decision makers, the interval analytic hierarchy process was used to calculate the index weight. An improved TOPSIS evaluation model was constructed by constructing a virtual negative ideal solution to avoid the same distance with positive and negative ideal solutions that might occur in the traditional TOPSIS. The Wuhan Yujingwan Project in China was selected for empirical research. The results showed that its sponge city performance was excellent, which was consistent with the actual situation. Compared with the analytic hierarchy process, the entropy weight method, and the traditional TOPSIS method, the advancement of the proposed method was proved.
摘要：
In recent years, various deep learning based methods have been successfully developed for change detection, such as Convolutional Neural Network (CNN) based U-Net and its variants, and Transformer based ones. However, CNNs lack the ability to effectively learn global representations, while Transformers neglect to learn local representations. Therefore, in this paper we propose a novel deep network, namely Multi-scale Attention based Transformer U-Net (MATU), to take advantages of CNNs and Transformers for learning both local and global features effectively. The backbone of our proposed MATU is a U-Net. In the encoder, a Siamese network is used to extract features from two input images, which is followed by a transformer module to further refine the feature pairs produced by the Siamese network. The difference of the refined feature pairs is fed into an Atrous Spatial Pyramid Pooling (ASSP) module to generate a distance map. Moreover, axial-attention blocks are integrated in the decoder with the corresponding multi-level feature differences of the encoder to progressively produce and improve the change map through attention upsampling. Extensive experiments on two widely used benchmark datasets SYSU-CD and LEVIR-CD demonstrate that the proposed MATU method achieves the state-of-the-art performance. Our code is available at https://github.com/easm002/MATU.

摘要：
In this paper, a low-temperature geothermal organic Rankine Cycle (ORC) power generation system model is established. R245fa is used as the circulating working fluid. The calculation program is compiled using the engineering calculation software EES, and the thermodynamic parameters and thermodynamic properties of the main state points of the ORC are theoretically calculated. The effects of narrow point temperature difference, evaporation temperature, geothermal water temperature and condenser end temperature difference on system performance are analyzed. The results show that the narrow point temperature difference has a significant impact on the ORC performance. Considering system performance and economic cost comprehensively, the best narrow point temperature difference and the best condenser end temperature difference are both within the range of 5-7 K.
