: With the development of my country's industrial level, the prefabricated building (PB) model has gradually become the mainstream. In order to more scientifically study the development policy of the prefabricated building industry, a system dynamics model with the boundary of resource input, technology research and development, production capacity and market demand system is constructed from the perspective of industry chain development, based on the influence of external subjects of the industry chain on the development of the industry chain. Afterwards, dynamic simulations of the development trend of prefabricated buildings under different policy scenarios are carried out. The results show that the increase in capital investment in the industrial chain and the improvement of the prefabricated assembly rate of government-invested construction projects are strong short-term incentive policies, while corporate tax incentives and prefabricated building purchase loan incentives are long-term incentive policies. Combined with the simulation results, the policy formulation recommendations based on the development trend of the industry chain are put forward.

: This paper discusses two different thermo-technical systems for heating and cooling the three-story office building under consideration. Data were collected on natural gas energy consumption over three-year period. The measured data on energy consumption for heating and cooling the building with an absorption heat pump using natural gas as fuel was analyzed. The only device that can replace the absorption heat pump in both the heating and cooling seasons is the vapor compression heat pump. The absorption heat pump has higher energy consumption than the vapor compression heat pump and its price is about 30% higher, but the financial cost of energy from natural gas is about 39% lower than the electricity cost of the vapor compression heat pump. The absorption heat pump is a better solution than the compression heat pump because the total financial costs, which include the investment costs and the energy costs over 20 years of operation, are about 9% lower and because the absorption heat pump heats up to an ambient temperature of ‒ 20 °C, which is not the case with the vapor compression heat pump.

: The paper introduces a fractal geometry utilizing an Octagonal Split Ring Resonator (SRR) hybrid DRA as its basis. The primary antenna consists of a conventional Octagonal patch, which is then scaled down by 0.5 in the first iteration and further by 0.25 in the second and then the DRA is utilized to enhance its performance. Remarkably compact at 6 × 6.2 cm, the antenna demonstrates effectiveness across frequencies of 5.1, 6.8, and 7.2 GHz notably; it maintains a gain above 3.3 dBi and directivity above 4.1 dBi in all operational bands. Analysis employing surface current and return loss substantiates the impact of the fractal design with DR. These simulations and measured results affirm the proposed antenna's suitability for robust C band wireless applications, offering promising performance in antenna parameters.

: Ancestral halls in Canton region are an important part of culture and architectural art in Canton region. Currently, research mostly analyzes from the perspective of clan culture and architectural crafts, and rarely explores architectural characteristics and inheritance from the perspective of cultural gene and constructs the gene map of architectural culture. Taking the theory of cultural gene as the starting point, this paper extensively studies the cultural background and inheritance process of cultural genes of ancestral halls in Canton region through literature research and field research. Based on the thinking method of gene reverse transcription in biology and the cultural three-level hierarchy, the main cultural factors were extracted and classified to establish the cultural gene library, gene hierarchical diagram and gene maps of Cantonese ancestral halls. The Analytic Hierarchy Process method (AHP) was used to screen and rank the cultural factors analyzing their importance in all levels in the cultural gene hierarchical diagram. To summarize, this paper discussed the development and evolution of cultural factors of Cantonese ancestral halls and their contemporary inheritance requires more attention on the innovative translation design of core cultural factors with higher importance, based on the principle of authentic and integral preservation of original, providing new perspective and decision-making references for the inheritance of ancestral halls in Canton region.

: It takes a long time to detect target information in noisy radar information and reduce the probability of false alarm. Therefore, it has become a research direction to reduce the probability of false alarm and the time of effective target detection. This paper introduces a new method to reduce the occurrence of false alarm in non-uniform environment and improve the efficiency of target detection. The proposed method involves a faster and more stable method that involves preprocessing the data set, splitting it into smaller parts, and utilizing a KTH minimum value M determined by an ordered statistics class constant false alarm detection algorithm. Each data point in the small segment is then compared to M , anything above M is classified as a target, and anything below M is ignored as clutter. Then ESVI-CFAR detection was performed on the selected target to obtain the final detection result. Experimental results show that the proposed method is superior to the traditional VI-CFAR and has better target detection performance.

: In order to determine the Lüders band propagation along the deformation zone length and width as affected by the force action direction, a detailed line analysis is performed by applying thermography and digital image correlation (DIC) during static tensile test at different test positions. The test is stopped at the point when the Lüders band propagation reached its middle to analyse temperature changes and deformations occurring in front of, on and behind the Lüders band front. Line analysis of the test samples confirmed that there are changes in the distribution of temperature and deformations. Across the width of the test sample, there are oscillations and differences in the distribution of temperature changes in the deformation zone. However, the same analysis showed that there are no differences in the change of deformations across the width of the test sample, except in the zone behind the Lüders band front where the Lüders band propagated. The influence of microstructure, i.e. the different dislocation density and the interaction of dislocations with fine precipitates, proved to be the cause of change in temperature and deformations measured at the moment when the Lüders band propagation reached its middle.

: The work proposed a novel model to accurately trace the pollution sources of water pollution incidents based on moth-flame optimization and Metropolis-Hastings sampling algorithms. The model first utilized moth-flame optimization to estimate the parameters of the pollutant migration-diffusion model by minimizing the error between monitored and predicted concentration. It then traced the optimal pollution source location, discharge volume, and time using the M-H sampling algorithm. Simulation experiments demonstrated the model achieved significantly lower errors in tracing pollution source information compared to a previous method, with relative errors within 1.33%. The new model provides an accurate and efficient approach to tracing water pollution incidents and overcomes the limitations of previous methods. It exhibits substantial potential in identifying pollution sources within real-world aquatic environments as well as facilitating prompt responses to mitigate environmental and health impacts.

: Last-mile delivery plays a crucial role in improving the service level of express delivery, as it involves direct contact with customers. Providing personalized last-mile delivery services is an important means of improving customer satisfaction. Massive consumer data makes it possible to mine customers’ personalized logistics preferences. The paper studies the vehicle routing problem in last-mile delivery considering customers' preferences. The paper first quantifies customers' preferences for delivery time, location, and mode, and obtains preference probabilities based on historical data. Then, an optimization considering customer satisfaction and enterprise delivery costs is established, and a vehicle routing problem model considering customer preferences is proposed. To solve the problem, we designed an adaptive large neighborhood search (ALNS) algorithm with virtual delivery points to solve the problem and proposed specific destroy and repair operators. Through the case analysis of an express delivery company, this article provides the optimal routs and analyzes the customer preferences on each route. In addition, this article explores the impact of the customer preference constraint and complaint constraint on cost and gives the appropriate customer preference constraint and complaint rate constraint from the perspective of cost-saving.

: This paper outlines a method for identifying and counteracting distributed denial of service (DDoS) and low-rate denial of service (DoS) attacks. These impair significant threats to network security and can disrupt the accessibility and efficacy of systems under attack. The proposed method combines Time-Frequency Analysis (TFA) using Short-Time Fourier Transform (STFT) and a Deep Learning model (DLM), namely Recurrent Neural Network (RNN), to enhance network security. By leveraging the strengths of STFT and RNN, the approach achieves improved detection capabilities and enables timely response and effective mitigation. The CICDDoS2019 dataset has been employed to conduct the evaluation, which provides a diverse set of realistic attack traffic scenarios. The results show that the proposed approach is effective, with an impressive accuracy rate of 99.1%. Compared to traditional methods, the integrated achieves higher accuracy and lower false positive rates. This research highlights the potential of Multimodal Fusion method, for addressing the growing need for advanced defense mechanisms in today's evolving threat landscape.
