Abstract: To address the concerns regarding a disused tailings pond, a closure engineering design and dam flood control safety evaluation were conducted. The proposed reservoir closure treatment methods, including adding flood drainage system (spillway), plugging the existing overflow tower and drainage pipe, were developed in combination with the construction conditions of the reservoir area. Then, hydrological calculations and flood routing for the tailings pond were performed, and the flood control safety of the tailings pond was evaluated. The results of the study indicate that after the designed closed pond treatment method for the tailings pond is adopted, a 1000-year design flood …would result in a flood elevation of 0.7 m, a minimum safety super-elevation of 2.0 m, and a minimum dry beach of approximately 130 m. These findings are in compliance with the relevant regulations and requirements of the specifications, and thus ensure the flood control safety of the tailings pond. Show more

Abstract: The decay behavior of a class of equation w t = - ∇ ⋅ ( w n ⁢ ∇ ⁡ Δ ⁢ w + α ⁢ w n - 1 ⁢ Δ ⁢ w ⁢ ∇ ⁡ w + β ⁢ w n - 2 ⁢ | ∇ ⁡ w | 2 ⁢ ∇ ⁡ w ) is considered under the Neumann boundary condition. The equation can be viewed as a generalization of the thin film …equation w t + ( w n ⁢ w x ⁢ x ⁢ x ) x = 0 , which can be used to describe the movement of the skinny viscous layer of compressible fluid along the slope. We obtain that the solution decays exponentially in L 1 -norm in the multi-dimensional case, and decays algebraically in L ∞ -norm in the one-dimensional case.

Abstract: In cloud computing, task scheduling is a critical process that involves efficiently allocating computing resources to fulfill diverse task requirements. To address issues such as unstable response times, extensive computations, and challenges in parameter adjustment faced by traditional task scheduling methods, an enhanced deep Q-learning cloud-task-scheduling algorithm was proposed. This algorithm utilizes deep reinforcement learning and introduces an improved strategy. The optimization of the objective function was achieved by defining the state space, action space, and reward function. The agent’s exploration capability was enhanced through the utilization of a UCB exploration strategy and Boltzmann action exploration. Simulation experiments were conducted …using Pycloudsim. The average instruction response time ratio and standard deviation of CPU utilization were compared to measure the advantages and disadvantages of the algorithm. The results indicate that the proposed algorithm surpasses the random, earliest, and RR algorithms in terms of the instruction-to-response time ratio and CPU utilization, demonstrating enhanced efficiency and performance in cloud-task scheduling.

Abstract: In the mechanics of materials, the integral method is often used to calculate the bending deformation of the beam. It is relatively simple to use this method under a single load. However, in real life, the load conditions of most beams are complex and diverse, resulting in more segmentation of the bending equation, too many integral constants, complicated equations involved, cumbersome calculation process, and heavy calculation. In order to solve this problem, the concept of singular function is introduced in this paper. By using a bending equation to express the bending moment internal force of the whole beam, and there …are only two integral constants after integration, which greatly simplifies the calculation process and reduces the calculation amount. This paper mainly introduces the properties of the singular function and how to use the singular function to express the bending equation of the beam, and solves the bending deformation of the beam with the boundary conditions, and discusses the application of the singular function in the calculation of the statically indeterminate beam.

Abstract: Engineering Planning is the primary task of underground engineering. The planning dimension of underground engineering still remains at the two-dimensional level, lacking a technical platform for processing and analyzing multi-dimensional and multi-source information. Especially due to insufficient information under hidden geological conditions, the quality of subsequent design and construction cannot be guaranteed.

Abstract: In recent years, deep learning technology has developed significantly in the judicial field. More and more scholars are introducing deep learning to solve problems in the judicial field and improve the efficiency of judicial agencies in handling cases. An important task of judicial work is to identify the key elements of complex cases, establish the relationship between entities in the document, accurately grasp the development of the case, provide a basis for the understanding, analysis, and ruling of the case, and increase the interpretability of the case results. However, judging from the actual application situation, the application of deep learning …technology in the judicial field is not yet mature and still faces huge challenges. On the one hand, the existing legal text element identification methods only consider the identification of core elements and ignore the basic elements. However, the basic elements contain necessary legal-related information, which is basic case information unique to the legal field and has important reference value for judicial staff to analyze cases. On the other hand, the traditional method of identifying key elements does not consider the contextual semantic relationship and ignores the element semantic information and global semantic information is lost, resulting in poor recognition of key elements of legal text. Therefore, in the identification of key elements of legal texts, not only the core elements and basic elements must be considered, but also the semantic features of sentences and the semantic features of elements must be comprehensively considered, thereby improving the effect of identifying key elements of legal texts and promoting the efficiency of judicial organs in handling cases. Aiming at the problem of identifying the basic elements of legal texts, this paper proposes a model for identifying the basic elements of legal texts based on dynamic representation. This algorithm uses the dynamic representation capability of the BERT model to vectorize text and considers global domain semantic information during the pre-training process to achieve a more comprehensive vector representation. Secondly, the memory component of the bidirectional long short-term memory network is used to integrate all the feature information between long-distance words in the legal text, effectively express the meaning of the word in the context, and realize the recognition of the basic elements of the legal text. In addition, the conditional random field model is used to learn the transfer rules of labels between entities and output the label sequence that best conforms to the actual rules. Finally, the basic element identification model proposed in this article has been significantly improved by comparing it with the current better methods. Show more

Abstract: In recent years, wireless charging technology for electric vehicles has received increasing attention. Existing research has been limited to the safety of specific body parts in the electromagnetic environment of wireless charging for electric vehicles, with insufficient consideration for the overall human body and the electromagnetic safety of implanted medical devices. In order to assess its safety in the electromagnetic environment more comprehensively, a three-dimensional electromagnetic simulation software based on the finite element method is used to construct models of the human body and implanted medical devices in the electromagnetic environment of wireless charging for electric vehicles. The study aims …to investigate the impact of this electromagnetic environment on the human body and implanted medical devices. The results indicate that, except for the maximum magnetic induction of 0.47 μ T at the ankle, which exceeds the limit, the magnetic induction intensity and electric field strength in important tissue areas, especially the upper trunk of the human body, are both below the safety limits specified by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines. For implanted cardiac pacemakers, the effective and peak magnetic field strengths are 13.7 A/m and 19.4 A/m, respectively, when the coil input power is 22 kW, meeting the relevant magnetic field strength requirements. The maximum temperature rise of the pacemaker is 3.2 × 10-3 ∘ C, and there are no significant changes in the temperature of the major organs in the human body after the implantation of the pacemaker. The thermal effects of electromagnetic waves on the temperature rise caused by implanted cardiac pacemakers have minimal impact on the human body. Show more

Abstract: Regional economic development objectives are improved economic, political, and social conditions in a certain area. Investment, production, innovation, wealth, and affluence are the four stages of regional economic development that may be identified in each selected area. It becomes more reliant on technological advancements in the industry and less on locally sourced production inputs as the economy region grows. The regional economic growth issue is inequality in the rates of improvement of subnational geographic regions and inequalities in the distribution of wealth. Intellectual algorithms or enhanced and hybrid algorithms based on machine learning, such as Fuzzy C-means clustering (FCM), principal …component analysis, and algorithm, can newly achieve more appropriate solutions to practical issues of discrete, non-linear, non-differentiable, and various constraints. A hybrid algorithm combines two or more other algorithms that solve the same problem. Hence, this paper proposes a Principal Component Analysis for the Sustainable Regional Economic Development (PCA-SRED) model to enhance the efficiency in examining regional economic changes and industrial development zones. The data are taken from the Organization for Economic Cooperation and Development (OECD) regional statistics dataset. Using PCA, industries may be categorized based on shared criteria, and the whole spatial distribution law of datasets and common patterns can be uncovered. To create a long-lasting regional economic development plan, it is crucial to categorize, compare, and evaluate the economic growth level of several areas. The research outcomes illustrate that the hybrid algorithms have high accuracy and a fast convergence rate because they can replicate the smart behavior of some clusters in nature while examing the variances in regional economic growth. The experimental outcomes illustrate that the recommended PCA-SRED model enhances the accuracy ratio by 98.2%, industry production ratio by 95.6%, regional economic change prediction ratio by 96.4%, and economic efficiency ratio by 97.8% compared to other popular models.

Abstract: Forestry listed companies are an important force in the development of the forestry industry, and their human capital level is related to organizational innovation driving ability, comprehensive performance, and thus affects the development of the forestry industry. There is little existing research on this topic. From the perspective of organizational resilience improvement, this article constructs an evaluation index system for human capital of Chinese forestry listed companies based on the annual report data of 61 Chinese forestry listed companies, focusing on knowledge human capital, capacity human capital, and proactive human capital. On the basis of determining the weights of each …indicator in the evaluation index system using analytic hierarchy process and entropy value method, the final weights are determined using the combined weights method. Obtain a comprehensive evaluation value of the human capital level of each forestry listed company and conduct cluster analysis on this basis. In terms of research objects, this article focuses on human capital of forestry listed companies; In terms of research content, establish a systematic evaluation index system; At the research level, quantitative analysis was conducted to achieve innovation. The research results indicate that the comprehensive evaluation value of the overall human capital level of each forestry listed company has a maximum value of 0.8245 and a minimum value of 0.0801, with an average score of only 0.2692. Overall, there is room for improvement. A total of 56 companies were relatively average and poor, reaching 92%. The overall human capital of forestry listed companies is relatively low, which is closely related to the weakness, core competitiveness, and high risk of forestry.

Abstract: This investigation explores the erosion dynamics in sandy soils triggered by underground pipeline fractures, applying transparent soil technology for visualization. Through this approach, the erosion process within the transparent soil model was meticulously recorded using photography, enabling the quantitative analysis of collapse pit dimensions over time. Results reveal that soil erosion primarily manifests directly above the pipeline fracture, varying significantly with hydraulic conditions. In scenarios devoid of water flow within the pipeline, an increase in collapse pit depth is halted, attributed to the accumulation and blockage of soil particles at the fracture point. Contrastingly, under half-pipe and full-pipe flow conditions, …the depth of the collapse pit swiftly reaches the fracture site. The flow of water notably escalates the expansion rate of the erosion pit, especially above the rupture, leading to continuous enlargement of the central area and subsequent secondary and tertiary collapses at the pit’s apex. The study further identifies the impact of water flow on soil scouring near the pipeline rupture, with pronounced effects in full-pipe flow, predominantly ahead of the rupture point, and less significant impacts observed in half-pipe flow scenarios. Differential image analysis facilitated the categorization of soil into distinct zones: collapsed, loosened, stable, and eroded, with a direct correlation observed between the extent of the loosened zone and the velocity of water flow.

Abstract: Existing research data has been confirmed that the impact of stairs on the overall structure cannot be ignored under the action of earthquakes. To further evaluate the influence of staircases on the seismic resilience of reinforced concrete (Abbreviated as RC) frame structures designed according to Chinese design specifications during infrequent earthquake occurrences, a dynamic elastic-plastic analysis method was utilised. Differences in parameters such as period, vibrational modes, interlayer displacement angle, and base shear force were explored between structures with and without staircases. Data comparisons revealed that, in contrast to frame-only structures, structures with staircases exhibited reduced interstory displacement angles, floor …displacement, and floor shear force under lateral loads, with the maximum reduction amplitude being 1.76%, 0.7%, and 1.82%, respectively. Such findings suggest that staircases enhance the lateral stiffness of the structure, thereby bolstering its seismic performance. Furthermore, it was observed that the variance in seismic performance attributed to staircases diminished as the number of storeys increased. The above research results can provide some reference for how to consider the influence of stairs in concrete structures. Show more

Abstract: In an era marked by rapid globalisation and digitalisation, the realms of education and technology are increasingly intersecting, particularly within the sphere of environmental design education. This study ventures into the integration of internet technology with environmental design pedagogy, emphasizing the development of a cross-disciplinary curriculum and a nuanced evaluation of its educational impact. Traditional research methodologies predominantly focus on short-term outcomes, often neglecting the longitudinal growth and deeper experiences of learners. Addressing this oversight, our research introduces an innovative curriculum system founded on knowledge graph techniques, aiming to enrich the educational content. The application of knowledge graph technology in …curriculum development is primarily manifested through the structured representation of course content, academic knowledge points, and their interconnections. By constructing knowledge graphs, educators are enabled to clearly identify the links and intersections between different academic fields, facilitating curriculum design that extends beyond the imparting of knowledge within singular disciplines to an integration of resources across subjects. This approach promotes the comprehensive application of knowledge and the cultivation of innovative capabilities. Alongside this, we employ a time series analysis for a more dynamic and detailed assessment of teaching effectiveness. This not only provides an academic benchmark but also charts a new course, offering actionable insights for educators in the field. Through this study, we aspire to bridge the gap between technology and environmental design education, ensuring a comprehensive and future-ready learning environment for students. In the context of environmental design education, the intrinsic connections between design principles, sustainability, and user experience are revealed through knowledge graphs. Within this framework, students are empowered to explore the application of these concepts in practical design projects. For instance, it becomes apparent that enhancing the user experience of a public space necessitates consideration of aesthetics, functionality, and environmental sustainability factors. Through this methodology, the use of knowledge graph technology not only enhances the coherence and systematic nature of course content but also fosters students’ creative thinking and problem-solving abilities, further driving the integration and innovation of education.

Abstract: With the rise of artificial intelligence, ships are gradually becoming intelligent. Ship path planning, as the foundation of ship intelligence, has become a current research hotspot. To achieve the planning of ship collision avoidance paths, a hybrid ant colony algorithm and artificial potential field for optimal safety path planning was proposed. The model makes up for the disadvantages of the slow convergence rate and the easy local optimum. At the same time, the ant colony algorithm in turn makes up for the poor global search ability of the artificial potential field method, so that the algorithm can achieve accurate path …planning. The test results show that in a simple environment, the hybrid ant colony algorithm, improved tangent and Dijkstra algorithm, and improved fast extended random tree * algorithm iterated about 7, 25, and 40 times respectively before starting to converge; In complex environments, the improved tangent and Dijkstra algorithms do not converge, while the improved fast expanding random tree * algorithm and hybrid ant colony algorithm iterate about 40 and 8 times respectively to begin convergence. It is clear that the mixed ant colony algorithm converges fast and can obtain the optimal path in the shortest time. The number of unsafe path points for the optimal path in a simple environment is 6, 1, and 0, respectively, for the improved tangent and Dijkstra algorithm, the improved fast expanding random tree * algorithm, and the hybrid ant colony algorithm; The number of unsafe path points for the optimal path in a complex environment is 9, 3, and 0, respectively; It can be seen that the path planned by the hybrid ant colony algorithm has higher security. The above results show that the mixed ant colony algorithm can effectively shorten the search time of optimal paths while improving the security of pathways. Show more

Abstract: Data support is already driving the development of artificial intelligence. But it cannot solve the semantic problem of artificial intelligence. This requires improving the semantic understanding ability of artificial intelligence. Therefore, a question answering system based on semantic problem processing is proposed in this study. The question answering system utilizes an improved unsupervised method to extract keywords. This technology integrates the semantic feature information of text into traditional word graph model algorithms. On this basis, semantic similarity information is used to calculate and allocate the initial values and edge weights of each node in the PageRank model. And corresponding restart …probability matrices and transition probability matrices are constructed for iterative calculation and keyword extraction. Simultaneously, an improved semantic dependency tree was utilized for answer extraction. The improved keyword extraction method shows a decreasing trend in P and R values. The improved answer extraction method has a maximum P -value of 0.876 in the training set and 0.852 in the test set. In a question answering system based on keyword and answer extraction, the improved method has lower loss function values and running time. The improved method has a larger area under ROC. The results of the validation analysis confirm that the improved method in this experiment has high accuracy and robustness when dealing with semantic problems. Show more

Abstract: The Bayesian optimization algorithm uses Bayesian networks as the probability model of its solution space. Although the research on this algorithm has steadily developed, there are still some problems in its application process, such as excessive computational complexity.

Abstract: To improve the economic benefits of river dredging engineering construction, studies have been undertaken to optimize construction period costs. This study suggests a scheme for optimizing schedule costs through the use of three algorithms: non-dominated sorting genetic algorithm with elite strategy, simulated annealing colony algorithm, and ant colony algorithm. To achieve the preliminary algorithm selection of construction duration cost, the objectives have single and multi-objective, and iterative models are constructed separately. The validation results showed that the simulated annealing algorithm achieved the optimal solution in single objective optimization after the 81st iteration. The optimal solution of genetic algorithm in multi-objective …optimization was a construction period of 49 days and a cost of 1788.15 million yuan. The non-dominated algorithm reduced the construction period to 313 days, which can save 52 days of construction period and reduce costs by 52.32 million yuan. This optimization algorithm has high efficiency in predicting shorter construction periods and lower costs, and has strategic foresight in the decision plans of decision-makers. Show more

Abstract: Internet of Things development is of great significance for modern society progress. However, the limited information in some areas with incomplete infrastructure restricts Internet of Things development, so the long-distance information transmission task of sensor nodes needs to be put on the agenda. The research introduces beamforming technology for clustering wireless sensor nodes, and proposes a clustering algorithm based on wireless sensor node’s energy consumption rate for nodes energy management to achieve remote information sharing and transmission. The results confirm that the success rate of clustering algorithm based on beamforming event triggering increases with node density increasing, and the success …rate is infinitely close to 1. In addition, when the sensor node is 120, the average charging delay time based on machine learning energy consumption prediction is only 946 seconds, which is reduced by 521 seconds compared to the Mean-shift algorithm. When sensor node is 120, the algorithm has a successful access count of up to 1288 times. These two clustering algorithms have good clustering performance and significant practical application effects, providing reliable technical support for remote data transmission in the modern Internet of Things.

Abstract: For the problem that massive data and cloud computing in the industrial Internet of Things cannot meet the requirements of low latency, a cloud hybrid network architecture is proposed. In the single user scenario, RS coding is used to realize data redundancy, and the security evaluation method is put forward on this basis. By using the ant colony algorithm, the data transmission delay and security objective function are established to obtain the best allocation scheme. In the multi-user scenario, the SD-CFIIoT architecture is constructed by combining SDN and fog computing technology. The optimal solution is found by applying the ant …colony algorithm to solve the objective function of the data transmission delay. Simulation results show that when the security constraint is 0.9, the data transmission delay of RS is 5.04 s, which is 0.18 s less than LDPC; 0.19 s less than MBR. When the safety constraint is 0.9, the delay of the cloud mixed structure is 5.82 seconds; 1.53 seconds less than the cloud core structure and 1.20 seconds less than the fog core structure. When the data volume reached 80 MB, the delay of SD-CFIIoT was 2.20 s, 6.61 s lower than the fog structure and 15.80 s lower than the cloud structure. The simulation results prove the effectiveness of the proposed scheme, which can ensure data security while realizing low delay data transmission, improve the efficiency of the Internet of Things, and then improve the industrial production efficiency. This has a certain positive significance to the industrial modernization and intelligent development. Show more

Abstract: The field of engineering is becoming increasingly complex. In order to adapt to the numerical simulation of solving the partial differential equation of functionally graded beam vibration, a higher order stable numerical algorithm has been constructed. Differential quadrature method is used in discrete space domain. The discrete variational method is constructed in the time domain. The index differential Algebraic equation are obtained by combining the two methods. The discrete variational scheme is constructed for simulation. The results indicate that under long-term simulation, both the velocity and displacement constraints of the Runge Kutta method have defaulted. Displacement constraint values differ by …5 × 10 - 10 . The velocity, displacement and acceleration constraints of the discrete variational method are stable. Compared with the Runge Kutta method, the constraint magnitude is reduced. The speed constraint is maintained at within 2.5 × 10 - 15 . The displacement constraint level is maintained at within 1 × 10 - 16 . This indicates that the discrete variational method has high accuracy and good stability when solving problems such as the vibration equation of functionally graded beams. When the step sizes are h = 0.1 m and h = 0.01 m, the accuracy of the discrete variational method is close. The larger the step size h , the higher the computational efficiency of the discrete variational method. The discrete variational method can maintain structural and energy conservation, making it suitable for long-term simulations. This has a good effect on solving complex problems in the field of partial differential equations. Show more

Abstract: Studying the seismic performance of assembled concrete structures is an effective means to improve the quality of buildings. In this paper, the primary focus was on elucidating the research objectives. Initially, seismic performance experiments for assembled concrete structures were meticulously designed, and subsequently, concrete structural frames were assembled for comprehensive experimental analysis. A finite element model was developed for the nodes of the assembled concrete structure, incorporating the concrete principal structure model, concrete damage plasticity model, and steel principal structure model. Numerical simulations and finite element analysis were performed to verify the specific factors affecting the seismic performance of the …assembled concrete structure. The results show that the hysteresis curves of the assembled concrete frame obtained from the simulation and the test curves basically match, and the difference in the maximum forward beam end displacement is only 1.76 mm, with an error rate of only 3.98%. When the axial compression ratio of the assembled concrete structural frame is within 0.3, there is no decrease in the bearing capacity when the assembled concrete is loaded to 2.3% lateral displacement. This shows that the seismic performance of assembled concrete structures can be effectively analyzed by using finite element models, and also provides a new research direction for improving the seismic quality of buildings.

The optimal values for learning …rate μ , momentum coefficient α , weight attenuation coefficient γ , and Dropout coefficient were 0.01, 0.7, 0.0003, and 0.5, respectively. The DCNN used in this article was iteratively trained with recurrent neural networks, convolutional recurrent neural networks, and transform domain neural networks for audio spectrograms, and the results were compared. The experimental findings indicated that the spectral recognition accuracy of DCNN was stable at 95.68%, far higher than the other three different networks.

Abstract: In order to solve these problems, this paper introduced the grey system theory (GST) method in the real-time application of intelligent traffic signal optimization (ITSO). In this paper, the deep Q-network (DQN) algorithm was used to realize the dynamic signal light setting of real-time traffic conditions, which can improve the overall operating efficiency of the traffic system, and the PPO (Proximal Policy Optimization) algorithm was used to solve the problem of the lack of real-time performance of the traditional traffic signal optimization methods. By comparing the traffic congestion index of S city before and after the application of the GST …method, the paper found that the average one week before the application was 60.1%, but it dropped to 26.6% after the application. In the experimental test of average speed comparison, the speed after applying the GST method was generally higher than the value before application, and the overall speed increase was about 20 km/h. This paper emphasizes the importance of evaluating the robustness of the GST method, particularly in its ability to manage unexpected scenarios.

Abstract: Conventional approaches to forecasting the risk of athlete injuries are constrained by their narrow scope in feature extraction, often failing to adequately account for temporal dependencies and the effects of long-term memory. This paper enhances the Long Short-Term Memory (LSTM) network, specifically tailoring it to harness temporal data pertaining to athletes. This advancement significantly boosts the accuracy and effectiveness of predicting the risk of injuries among athletes. The network structure of the LSTM model was improved, and the collected data was converted into the temporal data form of the LSTM input. Finally, historical data labeled with injury labels were used …to train the improved LSTM model, and gradient descent iterative optimization was used to adjust the parameters of the improved LSTM model. The improved LSTM network model was compared with the traditional athlete injury risk prediction model in terms of performance. The incorporation of enhanced LSTM networks for the analysis of temporal athlete data holds significant research significance. This approach has the potential to substantially enhance the accuracy and effectiveness of athlete injury risk prediction, contributing to a deeper understanding of the temporal dynamics influencing injuries in sports.

Abstract: In order to research the influence of bearing arrangement on the seismic response of urban viaduct, the 4 × 30 m standard span and C ramp bridge of the main line are taken as the engineering background. The SeismoStruct software is used to establish and analyse the seismic responses. For the standard span of the main line, under the same ground motion input, the internal force of the pier for the seismic isolation system is reduced by about 1 to 4 times compared with the ductile seismic system, but the displacement of the piers or the bearings …are relatively large, and the overall cost of the structure is high. For the C ramp bridge, the shear force, axial force and pier displacement with all lead-core rubber bearings are lower than those with fixed bearings. From the perspectives of structure seismic response, post-earthquake repair and engineering economy, it is suggested that the viaduct of the standard span should adopt the plate type rubber bearing, and the C ramp bridge should adopt the fixed bearing.

Abstract: Service discovery and composition are crucial tasks in the development of Web services, it is designed to select the appropriate services for each task and ensure that services are called in the correct order. Unlike traditional methods, we aim to solve the service composition problem from a new perspective by developing a novel service composition using semantics based natural language descriptions. The proposed algorithm employs a combination of natural language processing and semantic-based techniques to extract the functional semantics of service datasets and understand the user context. By parsing the user’s request, the method extracts possible sub-queries contained within the …request and identifies the appropriate combination of sub-queries. Leveraging the BM25 algorithm and the ESIM semantic matching model, the method identifies atomic services with high correlation with sub-queries and determines the composable atomic services set according to the defined composition constraints. Experimental results validate the efficacy of our method. Show more

Abstract: Low-credibility gossip information in social networks is a trigger for online opinion distortion. Since fragmented information always appears along with low content credibility and gossip, this paper put forward an online opinion distortion model based on DW algorithm, and information credibility, gossip intensity and opinion leaders were integrated in order to find out the mainly factors which induce opinion distortion. Then, four groups of experiment by using MATLAB were conducted, and the results show that the credibility of information is a key factor affects the speed of opinion, and also very important for the direction of the opinion dynamic of …the whole network. Online opinions can easily impact by the gossip information, and extreme gossip information causes serious division of opinion group, and the whole network opinions cannot be converged even in a quite long-time iteration. Super opinion leaders have the ability to balance the influence of gossip, even in an online environment full of gossip information. Based on these, a case study including 315 thousand records of posts and comments from Weibo is conducted for confirming the mainly findings in the simulation analysis, and strategies like high credibility information, low gossip probability, and behalf opinion leader are put forwarded finally for reduce opinion distortion.

Abstract: In recent years, detection methods based on deep learning have received widespread attention in the field of concrete crack detection. In view of the shortcomings of traditional image detection methods, a concrete crack detection method based on feature fusion is proposed. The Fourier frequency domain processed image is used as the input of the deep learning neural network. The original time domain image and the frequency domain image are respectively input into two feature extraction modules to extract high-level features, and then the two features are fused to fully characterize the characteristics of the time domain and frequency domain, and …finally the concrete crack detection results of the feature fusion are obtained. The performance of the proposed method is compared with VGG-16, AlexNet and DenseNet. Experiments show that the accuracy of the proposed method is higher than VGG-16, AlexNet and DenseNet. The proposed method has good results in concrete crack detection. To verify the generalization ability of the proposed model, the Concrete Crack Images for Classification data set was input into the proposed model for testing. The experimental results show that the proposed model has good generalization ability. Show more

Abstract: This paper describes a study on speaker recognition using the ECAPA-TDNN architecture, which stands for Extended Context-Aware Parallel Aggregations Time-Delay Neural Network. It utilizes X-vectors, a method for extracting speaker features by converting speech into fixed-length vectors, and introduces a squeeze-and-excitation block to model dependencies between channels. In order to better explore temporal relationships in the context of speaker recognition and improve the algorithm’s generalization performance in complex acoustic scenarios, this study adds input gates and forget gates to the ECAPA-TDNN architecture, combining them with CIFG (Convolutional LSTM with Input and Forget Gates) modules. These are embedded into a residual …structure of multi-layer aggregated features. A sub-center Arcface, an improved loss function based on Arcface, is used for selecting sub-centers for subclass discrimination, retaining advantageous sub-centers to enhance intra-class compactness and strengthen the robustness of the network. Experimental results demonstrate that the improved ECAPA-TDNN-CIFG in this study outperforms the baseline model, yielding more accurate and efficient recognition results. Show more

Abstract: Instinctive response was produced for protecting drivers from injury when facing incoming collisions. This study investigated the influence of instinctive response on lower extremity and knee airbag parameters. The change of posture, musculoskeletal characteristic and vehicle control parameters resulting from instinctive response were introduced in injury analysis. The key parameters of knee airbag were optimized based on a multi-object optimization algorithm of response surface method and NSGA-II. Results showed that the increased influence of musculoskeletal characteristic happened when the emergency level varied little. Injury in some cases might increase resulting from the early contact between airbag and lower extremity. It …decreased in different levels after the optimization of parameters, with maximum 20%. With the increment of emergency level, the best value of ignition time in the air area, mass-velocity ratio in the brake area and all vent hole ratio increased. Show more

Abstract: The explicit formulae for remainder of sum of powers of successive natural numbers (SPSN) divided by any prime factor p of the number N of sum terms is derived. The remainder is zero, if N contains p j , j > 1 . It is also 0, if j = 1 and the exponent is not divisible by p - 1 . The expression (N - N / p ) (mod p …), named “eigen-remainder” introduced for N is the remainder of SPSN in the rest of cases. All natural numbers, having all eigen-remainders equal to 1, are found not exceeding 42. It is demonstrated that in all other cases, there exists a prime divisor of N , which dividing SPSN gives the remainder ≠ 1. This proves Bowen’s hypothesis. Show more
