The better the literacy of the people, the better the level of thinking and the achievement of the progress of the community in various aspects of life. However, in reality our current literacy culture is still low.  Currently the partner has a side of the reading garden established in 2021 known as Fontabaca Park. But unfortunately, the establishment of a reading garden was not fully utilized by children and teenagers. This is exacerbated by the lack of reading material available in the reading garden. The lack of interest in reading or borrowing books is partly due to the lack of socialization related to literacy activities to children and adolescents in the Fontania region. The method of implementing activities starts from counseling, training, mentoring and evaluation. The results of each stage of the implementation activity start from the counseling activities carried out by analyzing the problem then continued with mapping the solutions provided for partners. Followed by providing training activities related to reading literacy and the formation of reading garden cadres. Mentoring activities are in the form of procurement of needed reading book materials and involving participants to label and collect reading books. Evaluation activities obtained an average percentage of 98% of the impact of activities carried out by the implementation team as an effort to optimize the existing Fontabaca park.

In social control, society plays a crucial role in preventing crime and ensuring criminal justice. To explain the phenomenon of crime, there are three schools of thought in criminology: classical criminology, positivism, and critical criminology. Crime is viewed as a social problem that can be understood not only from a legal perspective but also through scientific study. Sanctions are a normative aspect of the social control system, and sociologically, they cannot be equated from one region to another. The potential for social control of crime can be achieved through problem-oriented policing and community policing by analyzing various aspects related to public satisfaction with the performance and quality of police services. The way society responds to various criminal acts can be studied from criminological and sociological perspectives, and the role of judges in dealing with offenders is essentially one form of social control by society.

Background:

Cognitive assessment is a key component of clinical evaluations for patients with dementia and Alzheimer’s disease in primary health care (PHC) settings. The need for well-validated, culturally appropriate, and easy-to-use assessments is especially urgent in low- and middle-income countries (LMICs) that are experiencing rapid growth in their older adult populations.

Objective:

To examine the feasibility and demographic determinants of performance for a tablet-based cognitive assessment tool (TabCAT) battery, which includes subtests for four cognitive domains, among older PHC patients in southeastNigeria.

Methods:

A cross-sectional mixed-method descriptive study evaluating the useability and performance of TabCAT.

Results:

We enrolled 207 participants (mean age of 64.7±13.5 years; 52% with only primary, 41% secondary, and 7% tertiary education). Most (91%) who initiated the assessment were able to complete it, requiring 10–15 minutes to complete. More years of education was associated with better test scores across all tests ( p < 0.001). Living in a rural location was also associated with better performance ( p < 0.05). Male compared to female sex did not associate with performance on any of the tests (all ps > 0.05).

Conclusions:

Tablet-based cognitive assessment was feasible in rural and urban settings of Nigeria. Better performance on cognitive subtests linked to more education and residing in a rural area; however, sex did not predict performance. Digital cognitive assessment tools hold potential for widespread use in healthcare and educational contexts, particularly in regions with varying levels of urbanization and educational access.
State-space model for induction motors with static eccentricity faults
Authors: Gong Zifeng , Desenfans Philip , Pissoort Davy , Hallez Hans , Vanoost Dries
Published: August 2024

This work proposes a novel state-space model for eccentric induction motors, allowing the use of modern control theory to diagnose the eccentricity faults and to mitigate their effects. The proposed model is derived from the inductance-based multiple coupled circuit model. Instead of actual stator windings and rotor bars placed in slots, equivalent ideally distributed stator and rotor windings are considered in the motor modelling. The self and mutual inductances that incorporate the effects of static eccentricity in motors are evaluated using the modified winding function approach. Moreover, the rotor quantities are referred to the stator side to reduce the number of characteristic inductances. An eccentricity-oriented coordinate transformation is implemented to decouple the flux linkages in the new coordinate system and to reduce the system complexity further. Hereafter, stator currents and rotor fluxes are selected as system states, forming a fourth-order state-space model for the electromagnetic system of an eccentric motor. The proposed model is validated through comparisons with the reference data sourced from both the experiments and the finite element method. The potential of the proposed model for static eccentricity fault diagnosis purposes is explored.
Divisibility properties of sum of powers of successive natural numbers and Bowen’s hypothesis
Authors: Mestechkin M.
Published: August 2024

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 pj, 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.

Authors: Jin Songli , Gao Denghui , Zhang Renzhuo , Ma Junteng , Li Quanming
Published: August 2024

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.

Authors: Cheng Chenyu , Li Gang , Fan Jiaqing
Published: August 2024

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.
Automatic hierarchical background virtualization method for monocular vision image based on depth information extraction
Authors: Peng Mingcheng , Xie Wenda
Published: August 2024

Due to the influence of illumination, noise, distortion and other factors on monocular vision images, the image quality is reduced, the difficulty of image information extraction is high, and there are often errors and uncertainties in background segmentation, which affect the effect of monocular vision image background virtualization. Therefore, a new depth information extraction monocular vision image automatic hierarchical background virtualization method is studied to improve the effect of background virtualization. The depth information map is extracted by anisotropic thermal diffusion equation. The morphology is used to fill the tiny holes in the depth information map, and its smoothing process is used to determine the image depth range, automatically layer the depth information map, and obtain the foreground layer and background layer. The background layer is virtualized by Gaussian blur operation. Pyramid image fusion method is used to fuse the foreground layer and the blurred background layer to complete the background virtualization of monocular vision image. Experimental results have shown that this method can effectively improve the clarity of depth information map edges, preserve a large amount of image edge information, and have high structural similarity, with an average value of 0.96. The efficiency is high, and the background virtualization time is only 15 ms.

Published: August 2024

The volume and complexity of lighting system are increasing, and the traditional fault diagnosis method can not meet the requirements. It is proposed to use the strong knowledge association and analysis ability of knowledge graph on big data to assist fault analysts in the lighting system fault diagnosis. Firstly, the schema layer of the knowledge graph in the top-down style was designed, which defined the overall architecture of the lighting system fault diagnosis knowledge graph. Then, the BERT-BiLSTM-CRF model was constructed and trained for knowledge extraction by using self-built data set, and the data layer of the knowledge graph in the bottom-up style was built. And then, the fault diagnosis rule module was constructed and optimized by combining the knowledge graph with the deduction lattice algorithm. Finally, the knowledge graph was visualized by using the Neo4j graph database and its application process in fault diagnosis was analyzed. The experimental results show that the BERT-BiLSTM-CRF model has a 17.58% improvement in precision over the BiLSTM-CRF model for the lighting data knowledge extraction task, and has better accuracy and effectiveness. This method effectively improves the reliability and intelligent level of fault diagnosis of lighting system.
Chinese long text similarity calculation of semantic progressive fusion based on Bert
Authors: Li Xiao , Hu Lanlan
Published: August 2024

Text similarity is an important index to measure the similarity between two or more texts. It is widely used in many fields of natural language processing tasks. With the maturity of deep learning technology, a large number of neural network models have been used to calculate text similarity and have achieved good results in similarity calculation task of sentences or short texts. Among them, Bert model has become a research hotspot in this field due to its excellent performance. However, the application effect of existing similarity algorithms on long texts is not ideal, and they cannot truly extract richer semantic information hidden in the structure of long text documents. This paper takes Chinese long text as the research object, proposes a long text similarity calculation method using sentence sequence instead of word level sequence, constructs a long text semantic representation model with semantic progressive fusion, solves the practical problems faced by applications or natural language processing tasks related to long text semantics, in order to breaks through the bottleneck of long text similarity calculation.
Application of singular functions in bending deformation of material mechanics
Authors: Zhang Lunbin , Huang Juhua
Published: August 2024

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.

Published: August 2024

To improve the current source-grid, load-storage microgrid coordinated optimal scheduling method, which is not ideal in terms of efficiency and effectiveness, the study combines convolutional neural network, variational modal decomposition, and long and short-term memory neural network to realize the short-term prediction of microgrid electric load. Based on this, a mathematical model having source-grid, load-storage coordinated optimal scheduling and an improved particle swarm algorithm are proposed for it. Compared with the particle swarm backpropagation model, the proposed microgrid power load short-term prediction model reduces the average absolute percentage error and root mean square error by 0.38% and 39.5%, respectively. In addition, the economic cost of the proposed power grid coordination and optimization scheduling model based on improved particle swarm optimization algorithm (IPSO) is lower, at $3954.3, and the load fluctuation is less, at 56.6 W. This indicates that the model proposed by the research institute helps to achieve self-sufficiency of electricity within the microgrid and mutual assistance between microgrids, thereby tapping into scheduling potential, and also helps to achieve economic electricity scheduling strategies, avoiding unnecessary thermal power generation and carbon dioxide emissions, and improving reliability.

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. Therefore, the following policy recommendations are proposed: attach importance to the reserve of knowledge-based human resources and increase the proportion of employees with junior college degree or above in total employees; strengthen the construction of talent for technological breakthroughs and increase the proportion of R&D technicians ; pay attention to the improvement of the abilities of senior executives, directors, and supervisors, and optimize the structure of professional and technical titles; appropriately increase employee compensation levels and enhance employee proactive human capital utilization.

The impact of ESG on corporate financial performance: Based on fixed effects regression model
Authors: Dou Xinfeng , Yin Shengpeng
Published: August 2024

The fixed effects regression has become an important method for estimating causal effects from panel data. Drawing on a sample of 282 companies in heavily-polluting industries in China from 2018 to 2021, this study utilized the linear fixed effects regression method to empirically examine the relationship between ESG and financial performance. Specifically, the study employed variable replacement and IV-GMM approaches to conduct robustness tests. The empirical results reveal a significant positive correlation between ESG composite scores and financial performance. Among the dimensions (E, S, G), the E dimension shows a significant positive correlation, while the S and G dimensions lack a significant correlation. Notably, the E dimension most prominently promotes financial performance. In China, the impact is significant in the East but not in the Central or Western regions.
