Authors: Zhang Wen Xiao , Xiao Chun Ling
Published: July 2023

Background
As probiotics protect host cells, they are used in the treatment of bacterial infections. It has been indicated that probiotics may prevent or reduce the attachment of pathogens to host cells. In this study, Streptococcus strain D19T was isolated from the oropharynx of a healthy child, and its adhesion performance and Staphylococcus aureus adhesion-inhibitory effect were analysed using human bronchial epithelial (16-HBE) cells, as an in vitro cell model. We evaluated the probiotic properties of D19T strain based on its acid–base, bile salt, and lysozyme tolerance; antibacterial activity; cytotoxicity; antibiotic sensitivity; in vitro adhesion to 16-HBE cells; and competitive, exclusion, and displacement effects against S. aureus.
Results
D19T showed tolerance to a moderate pH range of 4–5 and 0.5–1% bile. However, it was more tolerant to 0.5% bile than to 1% bile. The strain also demonstrated an ability to adapt to maladaptive oropharyngeal conditions (i.e., tolerating 200 µg/mL lysozyme). It was resistant to 0.8 mM H2O2. The results also demonstrated that D19T possesses inhibitory activities against various common pathogenic bacteria. Furthermore, D19T was not toxic to 16-HBE cells at different multiplicities of infection and was sensitive to most antibiotics tested. The adhesion rate of D19T cells to 16-HBE cells was 47% ± 1.2%, significantly higher than that of S. aureus to 16-HBE cells. Competition, exclusion, and displacement assay results showed that D19T has good inhibitory effect against S. aureus adhesion.
Conclusions
The present study revealed that Streptococcus strain D19T has potential to be developed respiratory microbiota preparations.
Comparative analysis of RSM, ANN and ANFIS techniques in optimization of process parameters in laser assisted turning of NITINOL Shape memory alloy
Authors: Chakala Naresh , Sameer  , P Subhash Chandra Bose
Published: July 2023

The rationale behind the rising demand for orthogonal cutting in the processing of hard-to-cut materials is attributed to its advantages over discrete turning processes, which are achieved through the simultaneous application of two or more machining techniques. The utilisation of laser technology in machining processes is considered to be a sophisticated method for the processing of materials that are difficult to cut. The present study involved the utilisation of a Nd:YAG laser source to preheat a Nitinol shape memory alloy (SMA) work piece, which was subsequently subjected to machining using a laser-assisted Computer numerical control (CNC) turning centre. The objective of this investigation was to evaluate the properties of laser assisted machining (LAM) under varying machining conditions. The present study focuses on investigating the impact of process parameters on cutting force and surface roughness in the context of laser-assisted turning (LAT) of Nitinol SMA. To achieve this objective, statistical techniques such as the Response Surface Method (RSM), Adaptive Neurofuzzy Inference System (ANFIS), and Artificial Neural Networks (ANN) with Back Propagation (BP) algorithm-based numerical modelling are employed. The study was conducted utilising the Central Composite Design (CCD) methodology. The study examined the impact of process parameters, specifically cutting speed, feed, cutting depth, and laser power, on the response variables of cutting force (Fz) and surface roughness (SR). The results of the ANOVA analysis indicate that the cutting speed is the primary factor that significantly affects both Fz and SR, accounting for 31.39% and 60.36% of the variance, respectively. The feed rate is the second most influential factor, contributing 26.71% to Fz and 9.078% to SR. The optimisation of LAT parameters was ultimately achieved through the utilisation of a multi-objective desirability function, which effectively reduced both the SR and Fz simultaneously. The evaluation of the ANN model (4-24-2) involved its modelling and expected capabilities, which were compared to those of the RSM model using statistical measures such as root mean square error (RMSE) and absolute standard deviation. The outcomes of Fz and SR anticipated by RSM, ANFIS, and ANN exhibited a high degree of agreement with the empirical findings.

Published: July 2023

Background
Purine nucleoside phosphorylase (PNP) deficiency is a rare autosomal recessive combined immunodeficiency. The phenotype is profound T-cell deficiency with variable B- and NK-cell functions and results in recurrent and persistent infections that typically begin in the first year of life. Neurologic findings occur in approximately two-thirds of patients. The mechanism of neurologic abnormalities is unclear. Hematopoietic stem cell transplantation (HSCT) is the only curative treatment for PNP deficiency.
Methods
We report here six patients from five unrelated families with PNP deficiency treated in two centers in Turkey. We evaluated the neurological status of patients and compared to post-transplantation period if available. Then we performed PubMed, Google Scholar, and Researchgate searches using the terms "PNP" and "hematopoietic stem cell transplantation" to find all reported cases of PNP transplantation and compared to our cohort.
Results
Six patients were treated in two centers in Turkey. One patient died from post-transplant complications. The other four patients underwent successful HSCT with good immune reconstitution after transplantation (follow-up 21–48 months) and good neurological outcomes. The other patient with a new mutation is still waiting for a matching HLA donor.
Discussion
In PNP deficiency, clinical manifestations are variable, and this disease should be considered in the presence of many different clinical findings. Despite the comorbidities that occurred before transplantation, HSCT currently appears to be the only treatment option for this disease. HSCT not only cures immunologic disorders, but probably also improves or at least stabilizes the neurologic status of patients.

Published: July 2023

The Social Internet of Things (SIoT) is a new paradigm which represents a promising business solution proposed to exploit the large volume of data generated by the IoT devices. Accessing the shared resources and services in SIoT faces one major security challenge among others: access control. An access control mechanism evaluates the access policies and performs consecutive re-delegation operations based on delegation policies. However, the re-delegation cannot be performed when no trust relationships exist between the access requester devices and the permission delegator devices. To overcome this issue, we propose to perform friendship-based re-delegations through a path of trust social relationships. To find this path, we suggest to fetch the social device's profiles by integrating a caching strategy. The evaluation results show that a friendship-based delegation can be applied for any system distinguished by a distributed architecture, large scalability and high dynamicity such as the SIoT.

Authors: Ye Haotian , Liu Yihong , Schütze Hinrich
Published: July 2023

An interesting line of research in natural language processing (NLP) aims to incorporate linguistic typology to bridge linguistic diversity and assist the research of low-resource languages. While most works construct linguistic similarity measures based on lexical or typological features, such as word order and verbal inflection, recent work has introduced a novel approach to defining language similarity based on how they represent basic concepts, which is complementary to existing similarity measures. In this work, we study the conceptual similarity in detail and evaluate it extensively on a binary classification task.

Published: July 2023

In this work, new free base corroles (sulfophenylcorrole (mixture of tri(4-sulfophenyl)corrole and tetrasulfotriphenylcorrole) and tri(N-methylpyridin-4-yl)corrole triiodide) were synthesized and associative equilibria in aqueous and organic media were studied. Their binding ability to BSA and DNA was studied by various physicochemical methods. It has been established that complexes with DNA are formed only by cationic corrole, which binds to DNA by the intercalation method. Both cationic and anionic corroles bind to bovine serum albumin. It was found that the synthesized corroles are weakly fluorescent fluorophores and practically do not generate singlet oxygen; however, they are capable of generating superoxide anion radicals; can participate in type I photooxidation. The ability to initiate type I photoprocesses was established on the basis of the processes of photooxidation of nitroblue tetrazolium and BSA. The possibility of potentiating the process of protein photooxidation by potassium iodide has been established. Radical and radical ion reactions underlying the potentiation of BSA oxidation upon photoirradiation with PS were studied. It was found that the addition of KI significantly accelerates the photooxidation of BSA. It has been proven that the stage of formation of triiodide ions, which trigger a cascade of radical ion reactions, plays an important role in the potentiation processes.

Published: July 2023

Job recruitment is the process of picking a qualified candidate for a vacant position in an organization. Suitable job selection is a challenging task, especially for freshers. Every year, millions of students complete their graduation and come up with many options for choosing their jobs. This job selection procedure depends on various factors. Considering these issues, this research aims to build a model to predict whether a job is suitable or not suitable for a candidate according to their skills, experiences, and desires for the job. In this situation, Machine Learning approaches can be useful. Data were collected from 120 people currently appointed to a job in various fields. Distinct machine learning techniques are used to predict whether they are satisfied with their current job or not. We also find the other performance matrices and compare them with other algorithms to evaluate the performance of the best model. The results show that the random forest technique is the most effective method for forecasting appropriate job selection, with 92% accuracy and 8% error. Based on the findings, this research will become an effective tool for selecting a suitable job based on people's desires.

Authors: Li Tao , Guo Hongyue , Li Qingsong
Published: July 2023

In order to separate phenol from water, at 101.3 kPa, the liquid-liquid equilibria (LLE) data of water + phenol + solvents (trichloromethane, isoamyl alcohol) were obtained at 298.2, 303.2, and 313.2 K. The ability of the extractant to extract phenol from water was evaluated by the distribution coefficient (D) and selectivity coefficient (S). The Bachman and Hand equations were used to verify the reliability of the LLE data with the linear coefficient was greater than 0.98%. The LLE data was correlated with the NRTL and UNIQUAC models to obtain a binary interaction parameter with an RMSD not greater than 0.29%.
Neural Network-Based Classification of Atmospheric Circulation Types: A Novel Application of Autoencoders for Time Decomposition of Climate Data
Authors: Ibebuchi Chibuike
Published: July 2023

This study presents a novel approach that employs Autoencoders (AE) - a type of artificial neural network - for the temporal decomposition of sea level pressure (SLP) data represented in a T-mode structure where the columns or variables are time series and rows or observations are grid points. The analysis aims to explore the effectiveness of non-linear AE in overcoming potential limitations of linear models like Principal Component Analysis (PCA) in terms of classifying atmospheric circulation types (CTs) within the southern region of Africa. After applying both PCA and AE for the time decomposition of daily SLP data from 1950 to 2022, the resulting spatial composite maps generated by each method were compared to assess consistency. The findings reveal consistency between the spatial maps from the two methods, with 58% of the maps showing congruence matches greater than 0.94. However, when examining the correctly classified dates (i.e., the true positives) with a threshold of 0.8 congruence coefficient between the spatial composite map representing the CT and the dates grouped under the CT, AE outperformed PCA with an average improvement of 29.2%. Hence given the flexibility of AE and capacity to model complex non-linear relationships, this study suggests that AE could be a potent tool for climate data decomposition and CT classification, leading to a more accurate representation of actual circulation variability.

Authors: Elizalde-Barrera Cesar Ivan , Juarez-Mendoza Carlos Virgilio
Published: July 2023

Background:

HIV late-stage diagnoses have an important impact on mortality. Unfortunately, a significant number of patients are still diagnosed at late stages. On the other hand, the coronavirus disease 2019 (COVID-19) pandemic has created an unprecedented crisis in healthcare systems worldwide, including HIV care services.

:

The aim of this study was to compare time-trends in HIV late diagnosis, prevalence, and initial CD4
cell counts of newly diagnosed HIV-positive individuals at the entry to HIV care in a General Hospital
in Mexico City and to assess the Covid-19 pandemic possible effects on late diagnosis prevalence.

Methods:

We retrospectively analyzed the data of HIV-infected patients (January 1999 to December
2021) to assess the prevalence of Late presentation (LP, CD4 count < 350 cells/mm3) and
presentation with advanced HIV disease (AHIVD CD4 count < 200 cells/mm3). Differences across
time were evaluated, focusing on years of the Covid-19 pandemic.

Results:

We included 348 newly diagnosed HIV-positive individuals, of which 255 (73.2%) patients
entered into care with LP, and 158 (45.4%) were on AHIVD. The proportion of patients with
LP and AHIVD decreased significantly across the study period. Nevertheless, we found an increase
in this proportion in the years 2020 (70% and 53%) and 2021 (86% and 68%).

Conclusion:

Despite the progressive decrease in late diagnosis prevalence in our population, it remains
high. Even more, our results documented a possible increase in the prevalence of late diagnosis
associated with the COVID-19 pandemic. These findings highlight the need to prioritize interventions
to evaluate and reverse pandemic effects on people living with HIV care.
Applications of Radiopharmaceuticals in the Treatment of Cancer: Recent
Developments
Authors: Goyal Priyanshi , Malviya Rishabha
Published: July 2023

An emerging safe and efficient targeted method of treating many different types of cancer
is radiopharmaceutical treatment (RPT). RPT uses medications that either bind more selectively to
cancer cells or accumulate through physiological processes to deliver radiation either systemically or
locally. Nearly all radionuclides employed in RPT generate imageable photons, allowing for noninvasive
visualization of the therapeutic agent's biodistribution. RPT has demonstrated efficacy with
little toxicity when compared to practically all other systemic cancer treatment approaches. The tremendous
potential of this treatment is finally being acknowledged as a result of the FDA's recent approval
of many RPT medicines. The fundamental characteristics, clinical advancement, and related
difficulties of RPT are covered in this review.
A Robust Model for Optimum Medical Image Contrast Enhancement and Tumor Screening
Authors: Agarwal Monika , Rani Geeta , Dhaka Vijaypal Singh , Pradhan Nitesh
Published: July 2023

The use of medical imaging techniques have improved the correctness of disease screening and diagnosis. But, the quality of these images is greatly affected by real-time factors such as the type of machinery used, the position of a patient, the intensity of light, etc. The poorly maintained machines, incorrect positioning of patients, and inadequate intensity of light lead to low contrast and poor-quality medical images that work as hindrances in examining medical images. Thus, there is a need to upgrade the features of medical images. Researchers applied histogram equalization for contrast enhancement. However, it improves the visual appearance of medical images but faces the difficulties of over-enhancement, noise, and undesirable artifacts. Also, these techniques report low accuracy in tumor detection. Therefore, we propose an efficient model for medical image contrast enhancement and correct tumor prediction. The model performs segmentation, weighted distribution, gamma correction, and filtering to improve the visual appearance of MRI images. Further, it employs the optimum feature extraction for the correct detection of regions infected with tumors. Furthermore, findings obtained in a simulated environment demonstrate that our proposed model outperforms current models.
Communication mode selection and game theoretic bandwidth sharing model for D2D relay communication
Authors: Zaidi Syed Mohammad Abbas , Shaikh Aamir Zeb , Arfeen Asad
Published: July 2023

Device-to-device (D2D) communication plays a crucial role in achieving successful implementation of 5G+ and 6G wireless networks. The selection of the communication mode is a vital parameter that enables the activation of a communication link through D2D relays. Consequently, this selection can be considered the fundamental functionality responsible for activating the communication mode of transmission within any device-to-device communication network. This research paper proposes a communication mode selection scheme based on a hexagonal cellular structure. The scheme holds significant potential for application in various wireless transmission schemes. Additionally, the paper investigates the issue of bandwidth sharing in device-to-device networks. In future wireless systems, device-centric approaches will be widely adopted, necessitating a key focus on spectrum sharing. The proposed scheme not only facilitates wireless users in sharing their available spectrum with others but also allows them to receive financial rewards in return. This cooperative sharing approach fosters collaboration among wireless users. Furthermore, the paper compares the performance of two utility functions for the purpose of bandwidth sharing. The Cobb-Douglas model is utilized to present the proposed bandwidth-sharing scheme between two users. Simulation experiments are conducted to determine the percentage of bandwidth shared by the two users under various scenarios, including a case where both users share 50% of the bandwidth. The results indicate that the optimal utility function is achieved when one user shares 10% of the bandwidth while the other user shares 90%.

Authors: Mann F. A. , Pan Yi , Middleton John R. , Chairez Candida K. , Pyne Connor
Published: July 2023

OBJECTIVE

To compare complications between a modified incisional gastropexy (MIG) technique and standard incisional gastropexy (SIG).

ANIMALS

347 client-owned dogs.

PROCEDURES

Dogs that had undergone SIG or MIG from March 2005 through April 2019 were identified through a medical record search of the University of Missouri Veterinary Health Center. The MIG technique is identical to SIG except 2 additional simple interrupted sutures are added, 1 cranial and 1 caudal to the continuous suture line, going full thickness into the stomach to ensure engagement of submucosa. Medical record information was used to identify intraoperative, postoperative, and short-term complications, and telephone or email communication to pet owners and/or referring veterinarians was used to identify complications (short-term and long-term) after discontinuance of care at the University of Missouri Veterinary Health Center. Intraoperative, postoperative, short-term, and long-term complications were analyzed in aggregate within 6 matched groupings: (1) gastropexy for gastric dilatation-volvulus, (2) prophylactic gastropexy without other procedures, (3) gastropexy with ovariohysterectomy, (4) gastropexy with castration, (5) gastropexy with splenectomy, and (6) gastropexy with celiotomy other than splenectomy. Overall rates of complications potentially attributed to gastropexy were compared between SIG and MIG using the Fisher exact test. Overall rates of complications not attributed to gastropexy were compared between SIG and MIG using the χ2 test.

RESULTS

There were no significant differences in overall complication rates between SIG and MIG.

CLINICAL RELEVANCE

Surgeons who feel that engagement of gastric submucosa is important for gastropexy success may use the MIG technique with minimal fear of complications. However, superiority of one technique over the other cannot be determined on the basis of this study.

Authors: Wang Chen , Li Shuo
Published: July 2023

To strengthen the comprehensive literacy of college students and have a correct aesthetic concept, the cultivation of innovative talents in modern college aesthetic education under big data is proposed. The mixed-filtered college aesthetic training data were used to calculate the prediction function, loss function, and regression parameters using a logistic regression model. The training sample probabilities are derived from the maximum likelihood function to predict the unmade scores in the teacher’s scoring matrix, which is trained to fit the original scoring matrix. The behavior of each student is divided into a corresponding label, and the aesthetic education courses with historical preferences of students in the same category are recommended to the target students in that category. By iteratively updating the values of each cluster center one by one, the data with high similarity are clustered into one class, and the distances of all the cluster centers are recalculated to alleviate the data sparsity problem and scalability problem of logistic regression. The information of the training set is used as input data, and the numerical type indicators are used as the basis for judgment to obtain the satisfaction situation of students with the recommended results, and the indicators for visually evaluating the gap between the predicted and real ratings of the system and the accurate and complete data on the cultivation of innovative talents in modern university aesthetic education are counted. The analysis results show that under the big data technology, the physical education courses in colleges and universities carry out the education of the concept of beauty, the innovative form is better, and the percentage of the concept of strength and beauty reaches 69%, strengthening the ability of college students to feel beauty.
Corporate employee performance mechanism based on incomplete information contest theory
Authors: Ning Xi
Published: July 2023

Small and medium-sized enterprises (SMEs) are the mainstay of China’s social and economic development, and the implementation of performance appraisal systems in SMEs is an important way for enterprises to promote the growth of their employees, and each enterprise has a performance appraisal system that matches the characteristics of its own corporate culture. However, at present, objective factors such as the scale and operation of SMEs in China lead to the fact that employee performance appraisal cannot play a good role, and the decision-making level of SMEs understand the implementation of the performance appraisal for subordinate employees in a formal way, and cannot develop a performance appraisal system that is in line with the enterprise itself by combining with its development status. A reasonable performance appraisal system can improve the corporate cohesion and industry competitiveness of the company’s employees. The imperfection of the current corporate employee performance mechanism is not addressed, and the planning of objective employees is not uniform and reasonable enough. This paper constructs a model by analyzing many factors influencing the implementation of performance appraisal systems in SMEs and combining them with incomplete information race theory. Ultimately, we explore the strategies and methods of the performance appraisal for SMEs, cultivate talents for SMEs, enhance the sense of belonging and creativity of enterprise employees, and provide a strong guarantee for enterprise development.

Authors: Fan Fei , Huang Cong
Published: July 2023

Due to the diverse development trend of modern media, new media arts and applications are being presented in the field of vocal performance teaching with its many advantages of interactivity, immediacy, sharing, comprehensiveness, versatility, community, and personalization. In this paper, by decoding the EEG signal, through the decoding process of EEG data pre-processing, feature extraction, feature identification, and classification, and calculating the significance of each element in the time-frequency matrix, an iso-dimensional mask matrix can be obtained. Then the conditional random field model is established on the random field theory to get the parameters of the model. Finally, the parameters of the model are obtained by maximizing the following entropy function, which is brought into the Lagrangian operator to obtain the pairwise Lagrangian operator. Finally, the EEG signal is decoded to realize the self-control training of vocal performance teaching in the new media environment. The experimental results show that by conducting the intervention test on self-control and vocal performance insight, the mean value of the total self-control score in self-control training is 61.99±11.45, and the intervention effect has stability. Therefore, improving self-control, forming correct expressions and forms, and enriching emotions are important for vocal performance.

Authors: Ma Hongzhi
Published: July 2023

For the complex background of traditional radar image target detection methods is affected by multiple interferers, which leads to a low recognition rate of multi-target classification and a high false alarm rate. In this paper, the current hot research BM3D denoising method is introduced into radar image target detection. Firstly, the detection process of the BM3D algorithm is constructed, and the image pixels are reasonably clustered by denoising so that the image blocks in homogeneous regions have a high matching degree and those in non-homogeneous regions have a low matching degree. Secondly, the clustering recognition feature is used to limit the search range of similar blocks to homogeneous regions, to improve the denoising efficiency of the algorithm. Finally, the simulation results of this paper show that compared with previous algorithms, the BM3D detection method has significantly improved in both the subjective visual effect map and objective numerical indexes. For example, the image denoising quality is improved by about 0.716dB on average and up to 1.031dB, the image denoising time is shortened by about 19.962s on average, and the algorithm runs 1.211 times faster than the original algorithm. It is proved that the algorithm can improve denoising efficiency and reduce computational complexity while enhancing detailed information.

The interdisciplinary study of mental health education and digital music in colleges and universities is an indispensable part of China’s education discipline system. To solve the current problems of mental health education in colleges and universities, this paper analyzes the promotion role of digital music and the development of mental health in colleges and universities. The hierarchical analysis method is used to build a mental health assessment index system in colleges and universities. Using the VPMCD method, based on the intrinsic relationship between different index characteristics, a digital music-based psychological health assessment model for colleges and universities is established to assess the psychological health problems of college students. According to the psychological assessment results, the listening psychological intervention method is used to psychologically intervene with students. And by calculating the main melody of digital music materials, the type of music intervention materials used was determined. Experimental results: The listening psychological intervention method successfully led to the slow recovery of students with severe and moderate mental health problems and the complete recovery of students with mild psychological problems. 11 students (9.2% of the total) were completely cured of their psychological problems among the freshmen students in college A. The number of students who reduced their psychological problems was 86, accounting for 81.1% of the total. 26 students, accounting for 32.3% of the total, were completely cured of their psychological problems in their sophomore year at College A. The number of students who reduced their psychological problems was 56, accounting for 51.3% of the total. It proves that: digital music plays a supplementary role in college mental health education and proposes a new way of implementation for college mental health education. It promotes the diversified development of mental health education in colleges and universities as well as the cultivation of positive psychological qualities of college students and guides them to grow up positively and healthily.

The cultural tourism industry and the tourism industry are both different and interrelated, and both are the most promising industries in the modern service industry. Along with the continuous socio-economic development, the influential role of cultural values is expanding and is an inevitable and positive industrial development trend. The globalization of the economy, changes in transportation and information technology, and the widespread use of the Internet have brought about a continuous increase in tourist demand, an essential change in the relationship between all relevant stakeholders in the cultural tourism industry, and an increasing complexity of development. The traditional linear approach to analyzing the components of the system ignores the complexity and dynamics of the cultural tourism industry, and it is difficult to adapt to the development practice. The results show that: after a major national public health outbreak of SARS at the end of 2002, the number of tourism receivers in Shanghai grew -by 13.11%; the number of tourism receivers in Shanghai grew by 24.82% with the bid for the Chinese Olympic Games in 2008, and the evolution of Shanghai’s cultural and tourism industry system has the characteristics of a small world and an approximate scale-free network, which behaves as a chaotic deterministic nonlinear dynamical system; the integration of Shanghai’s cultural and tourism industry follows “orderly - chaotic edge - emergent - new orderly”, the process of jumping up from low-level orderly to high-level orderly evolution; This paper provides a precise analysis of the evolutionary path of the cultural tourism industry, which effectively assists cultural tourism industry managers in adaptive management and regulation by providing methodological and technical support.

In today’s highly developed technology, computer and Internet technology has seen a climax of innovation and its application areas are becoming more and more extensive. Computer simulation technology is the direction of computer development proposed in recent years, which can change our way of life to a greater extent. In order to explore the role of finite element analysis in structural analysis and computer simulation, this paper uses ANSYS finite element analysis combined with structural analysis methods and verified by computer simulation examples of welding thermal cycles. The results show that the computer simulation of the simulated temperature curve trend and the experimentally measured temperature curve is basically the same. Absolute error curve increases first and then decreases, basically at 11 s when the maximum, followed by a rapid decline, and then gradually slow down the rate of decline, and eventually converge on 200 °C or 180 °C or so. Such a computer simulation in a certain range to be able to more accurately simulate the welding temperature field, the study of welding problems is very valuable reference. For the simulation speed of computer simulation, combined with the structural analysis of finite element analysis, the running time was reduced by an average of 3.58 min, and the overall efficiency was improved by 21.81%. It shows that the FEA method can effectively reduce the running time and significantly improve the running efficiency. In summary, finite element analysis can optimize common problems in structural analysis, strengthen the analysis effect, and expand the application of computer simulation technology.
