Influence of working pressure on laser beam welding in vacuum of electrical steel sheets

In a recent research project of RWTH Aachen University it is shown, that laser beam spot welding is advantageous over line welds with respect to the magnetic properties of an iron core and can therefore increase the efficiency of electric motors. In this case laser beam welding in vacuum is used to join these iron cores. A pulsed laser beam process was used to generate individual weld spots. The influences of a reduced working pressure on the welding result in the range of 1 mbar–1000 mbar occurring in this process are presented in this paper.

PO33 Presentation Time: 10:30 AM: Testing the Usability of the Vaginal Speculum Tongue Made of Polyetheretherketone Material in Brachytherapy by Dosimetry Method

<h3>Purpose</h3> In the tandem + ovoid brachytherapy application, during the metallic speculum removing process after the vaginal packaging process, the positions of the sponges may change due to the spoon-shaped structure of the speculum, and this situation may cause not desired efficiency from the packaging process. In this project, we aimed to 3D printing of vaginal speculum tongues from polyetheretherketone (PEEK) material and make the dosimetric evaluation to assess usability during packing in gynecologic brachytherapy. <h3>Materials and Methods</h3> In this study, we designed a modular structure in which the upper and lower tongue can be easily separated from the handle similarly to the metallic vaginal speculum we use in our routine practice with no requirement to remove the speculum tongues from the patient after packaging. The tongues of the designed speculum were produced with PEEK material with a layer thickness of 200 microns using a 3D printer (Intamsys Technology Co. Ltd., Shanghai, China). To evaluate the radiation permeability of the produced speculum tongues, a phantom containing water was designed to perform dosimetric studies and 2 different dosimetric methods were used such as the treatment planning system (TPS) and Radiochromic Film Dosimeter system (Gafchromic: EBT3). TG43 and ACUROS BV algorithms are used as TPS. Prescribed dose (3 Gy) at the surface of phantom (side with the speculum) was calculated for a single source Dwell position in TPS using with ACUROS BV algorithm. The irradiation time was 631.1 seconds for both algorithms. The activity of the radioactive source was 11,086 Ci. The measured values that were obtained from the same points with different techniques were recorded and relations with each other were evaluated by using the Pearson Correlation test. In each measurement method, dose values were recorded in 4 different directions such as right (with no speculum), left (with speculum), up, and down. Dose-distance graphs were created for each direction from these values, and no break in the curve was detected on the side of the speculum tongue in phantom. This work was supported by Eskisehir Osmangazi University Scientific Research Projects Unit as project number TSA-2021-2143. <h3>Results</h3> The measurement values obtained from two different TPS algorithms and the film dosimetry method are given in Figure 1, and no significant difference was found in the statistical evaluation. The values obtained by using different methods show parallelism with each other, and no breakage was detected due to the speculum tongue. <h3>Conclusions</h3> In conclusion, all values obtained from TPS and radiochromic film dosimetry were parallel to each other. When the dose values at the same points and dose-distributions were evaluated, we concluded the speculum tongues we produced from PEEK did not have any negative effect on the dose distribution. However, this proposition needs to be supported by making more measurements with different dosimetry methods.

Effect of transcutaneous posterior tibial nerve stimulation and repetitive transcranial magnetic stimulation on neurogenic overactive bladder symptoms in female patients with multiple sclerosis: The study protocol of a randomized controlled study.

Neurogenic bladder is frequently seen in patients with multiple sclerosis (MS). Electrical stimulation methods (neuromodulation) can be used for patients that have persistent symptoms despite pharmacological treatment. This study aims to compare the effects of two different neuromodulation techniques used in the treatment of neurogenic bladder. This is a single-center randomized controlled trial for MS patients with neurogenic bladder. Patients determined to be eligible according to the study criteria will be randomized into two treatment groups: the transcutaneous posterior tibial nerve stimulation (PTNS) and repetitive transcranial magnetic stimulation (rTMS) groups. Each group will include eight patients. The patients will be treated for a total of 10 sessions for two consecutive weeks. The pressure-flow study will be used to compare the initial and final urodynamic results as the primary outcome. All the participants will fill in a 3-day bladder diary before and after the treatments in each group. Patients will also be asked to complete specific questionnaires for incontinence and quality of life (QOL): Overactive Bladder Questionnaire-V8 score (OAB-V8), Incontinence Severity Index (ISI), Incontinence Quality of Life Scale score (I-QOL), International Incontinence Questionnaire (ICIQ-SF) score, and International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) score) as the secondary outcomes. An ethical approval number was obtained from the Non-Invasive Clinical Research Ethics Committee of Istanbul Medipol University (ethical approval number: 768). Support was received within the scope of the Istanbul Medipol University Scientific Research Project with project number 2020-2017. The result of this study will be published in a peer-reviewed journal. NCT05312138.

Implementer Views on Whether Catch-Up Education Program in Primary Schools (Iyep) Could Be Performed Via Distance Education

Face-to-face education in many countries was suspended due to the global pandemic of COVID-19 declared by the World Health Organization (WHO) in 2020. The pandemic led to new searches in the academic process, and distance education gained importance in Turkey. However, the Catch-Up Education Program in Primary Schools was not taken into account while it was stated that educational services provided in resource rooms within the scope of inclusive education were to be continued via distance education. Accordingly, it was aimed to examine the views of classroom teachers who had implemented IYEP before on whether IYEP could be performed via distance education and to make an evaluation based on the first-hand experiences of implementers. To that end, the research was conducted with 22 participants in accordance with the ethical principles. Ethics committee approval was obtained for the study with the decision of Agri Ibrahim Cecen University Scientific Research Ethics Committee dated 08.09.2021 and numbered 206. All of the participants are experienced classroom teachers who have experience with IYEP and have performed distance education. The research was performed with the phenomenological design of qualitative research designs. The data were collected with a semi-structured interview form, and the interview questions were finalized after having been reviewed by two academics who are subject-matter experts. The data obtained in the research were subjected to descriptive analysis individually by the researchers and evaluated. It was concluded that IYEP could be continued via distance education when the face-to-face education could not be performed, but there were several concerns about the matter at hand. The participants often mentioned that distance education could not substitute for and be as effective as face-to-face education. Nevertheless, despite certain disadvantages, considering the contributions of IYEP in face-to-face education, it was found that distance education could be utilized so that shortcomings in learning would not accumulate and extend to the next year and that experiencing IYEP via distance education could provide ideas about future practices.

Identification of Scientific Research Evaluation Indicators of College Teachers Based on Wireless Communication Network

The evaluation indicator of teachers’ scientific research is a very important criterion in the evaluation of teachers’ scientific research in colleges and universities. Generally, indicators are divided into three levels, and each indicator setting must be very precise. Many indicator systems for college teachers have been created at present. However, there are some problems in the identification of indicators in the evaluation process. There will be cross-repetition between indicators, and the quantification of indicators is not detailed enough, resulting in inaccurate results. To solve these problems and make the evaluation results more fair and accurate, this paper took a university as a case, a deeply discussed method based on wireless communication network, and conducts an experimental analysis on the identification of university teachers’ scientific research evaluation indicators. Using the method of wireless communication network, the problem of index identification was analyzed, and the experimental research of index identification was carried out by using wireless communication network. The results showed that the index of engineering teachers’ practical ability was relatively high, and the weight value was 0.38. The liberal arts was relatively low, and the weight value was only 0.26. However, on the cognitive index, the weight value of liberal arts was the highest, with the weight value of 0.33 while that of engineering was only 0.28. It can be seen that the method applied in this paper greatly improved the efficiency of the whole evaluation, and it made the index recognition more rapid and accurate. Therefore, further research on wireless communication networks and index identification can be considered.

Search for single production of vectorlike B-quarks at the LHC* *Supported by the Foundation of the Key Research Projects in Universities of Henan (22A140019), the Natural Science Foundation of Henan Province (222300420443) and the Project of Innovation and Entrepreneurship Training for College Students in Henan Province (S202110478024)

New vectorlike quarks have been proposed in many scenarios of new physics beyond the Standard Model, which address the hierarchy problem and may be potentially discovered at the Large Hadron Collider (LHC). Based on a model-independent framework, we propose to search for the vectorlike B-quark (VLQ-B) and focus on resonant production via b-gluon fusion through chromomagnetic interactions. We then explore the possible signals of the VLQ-B through the decay mode at the 14 TeV LHC. After a rapid simulation of signal and background events, the excluded regions and the discovery reach in the parameter plane of are obtained at the LHC with an integrated luminosity of 300 (3000) fbin the dilepton final states.

THE MODERATING EFFECT OF JOB SEARCH INTENSITY ON POSTGRADUATES' COMPREHENSIVE ABILITY, EMPLOYMENT PERFORMANCE AND PSYCHOLOGICAL ANXIETY SENSITIVITY

BackgroundWith the increasing number of college students in China year by year, the employment situation of college students is becoming more and more serious. In this context, more and more students have participated in various comprehensive ability activities in school, so a series of questions need to be solved and answered urgently, such as whether the improvement of these abilities can make students more competitive in the job market, and whether the degree of competition in the job market will affect the employment performance of college students. The research questions of this study are as follows: (1) whether the comprehensive ability obtained by students through conscious participation is conducive to job hunting; (2) How different comprehensive abilities play a role in job hunting. (3) Whether the pressure of the job market affects the motivation and willingness of students to improve their comprehensive ability. It also analyzes the anxiety phenomenon of students after employment.Subjects and MethodsThis study used questionnaire survey to obtain data. The variables were measured by the existing maturity scale, and 300 valid questionnaires were obtained through the online questionnaire. The reliability, convergent validity and differential validity of the variables were good. Using the methods of descriptive analysis, analysis of variance, regression analysis and adjustment effect analysis, this paper makes an empirical analysis on the adjustment effect of the seven dimensions of College Students' overall ability on the relationship between job hunting intensity and job performance. We use Kim's job anxiety scale as the measurement scale, and use Likert scoring method to evaluate the scale. Pearson correlation, standard deviation and statistical significance are combined to illustrate the correlation. T-test of independent samples was used to verify the difference between high anxiety group and low anxiety group. According to the statistical value of anxiety, participants were divided into three groups: low, medium and high anxiety groups. The questionnaire includes two kinds of anxiety, namely debilitating anxiety and promoting anxiety. Through t-test, univariate and multivariate analysis of variance and regression analysis, we investigated the relationship between job-hunting anxiety, self-efficacy and comprehensive ability of students of different majors and genders.ResultsThe relationship between College Students' comprehensive vocational ability and employment performance is regulated by the intensity of job hunting. Employment intensity has a negative impact on the relationship between College Students' comprehensive vocational ability and employment performance. The empirical analysis based on SPSS software shows that the seven comprehensive abilities of college students, such as intelligence ability, social communication ability, social adaptability, problem-solving ability, self-development ability, personal execution ability and emotion regulation ability, have significantly improved the employment performance of college students. Job hunting intensity negatively regulates the positive correlation between College Students' intelligence ability, social communication ability, social adaptability, problem-solving ability, self-development ability, personal execution ability and emotional regulation ability and employment performance. In the process of the influence of job-hunting on anxiety, emotional response plays an intermediary role, and psychological elasticity plays a regulatory role. Job-hunting activities are regulated by psychological elasticity through the intermediary effect of emotional response on anxiety. That is, the higher the psychological elasticity, the lower the influence of job hunting on anxiety through coping styles; On the contrary, the lower the level of psychological elasticity, the higher the effect of job hunting on anxiety through coping styles.ConclusionThe significance of this study is that college students should not only pay attention to the study of professional courses, but also comprehensively enrich and supplement their abilities through seven dimensions to improve employment performance. As a social phenomenon, the intensity of job hunting cannot be changed by individuals. College students need to improve their comprehensive ability and actively pay attention to the changes of the employment market. Research limitations: future research can focus on the relationship between employment pressure and professional development of students in different majors, so as to draw analytical conclusions among professional groups in different disciplines. In short, we should give full play to students' self initiative, strengthen their self-regulation ability in job-hunting activities, and actively pay attention to their psychological, emotional and behavioral changes.AcknowledgementsSupported by the projects: Innovation Project of Guangxi Graduate Education: Research on the Cultivation of Professional Development Ability of Master of International Business (Grant No.:JGY2020177), Guangxi Higher Education Reform Project: Research and Practice of Deep Modular Teaching Reform Based on the Integration of Industry and Education (Grant No.: 2019JGA241), and the project of major scientific research projects in Colleges and universities in Guangdong (Grant: 2021ZDJS122).

RESEARCH ON THE INNOVATION OF TEACHING MODE OF “FRESHMAN SEMINAR” IN APPLIED UNIVERSITIES UNDER THE CONCEPT OF OBE BASED ON THE CHANGE OF EMOTIONAL BEHAVIOR -- TAKING PHYSICAL EDUCATION MAJOR OF NANCHANG NORMAL UNIVERSITY AS AN EXAMPLE

Abstract Background “Freshman seminar”, as the first important learning revolution course for freshmen, originated in American colleges and universities in the middle of last century. It was not until 2003 that some research universities in China gradually launched the “freshman seminar”, which has become one of the most popular courses for the group. The course was set up late in application-oriented undergraduate colleges, and the overall teaching staff, teaching content, teaching mode and teaching evaluation are still immature and still in the exploratory stage. In particular, the emotional changes of students are not clear enough. Research design Taking the “freshman seminar” of physical education major in Nanchang Normal University as an example, this paper investigates the current situation and confusion of physical education teachers and students in Nanchang Normal University in 2019, 2020 and 2021 by means of questionnaire and interview. A total of 268 valid questionnaires were obtained. There were 6 questionnaires for teachers and 262 questionnaires for students. In order to study the impact of emotional regulation on female employees' retirement decision-making, the study adopts the Core Self-evaluation Scale. The core self-evaluation is measured by the core sel evaluation scale (CSES) compiled by judge et al. The scale consists of 10 items and adopts Likert 5-point scoring method. 1 ~ 5 points represent “very inconsistent” to “very consistent”. Previous studies have shown that the scale has good cross-cultural applicability. The internal consistency of the Core Self-evaluation Scale in this study α The coefficient is 0.824. 1.2.3 the emotional regulation self-efficacy scale adopts the emotional regulation self-efficacy scale (REEs) compiled by Caprara. Domestic research shows that the scale has high reliability and validity and is suitable for Chinese people. The scale adopts lik ⁃ ERT 5-point scoring and includes three dimensions: adjusting positive emotional efficacy, adjusting depression / pain emotional efficacy and adjusting anger / anger emotional efficacy. Emotion regulation self-efficacy scale Research results The teaching form of the freshman seminar in the Department of physical education of Nanchang Normal University is still based on the traditional theoretical lectures of administrative courses, and there is a lack of effective teaching means and methods to guide students to actively discuss. Another factor leading to the poor effect of classroom discussion is the lack of communication between teachers and students before class and students' ignorance of learning objectives. Single evaluation methods and relatively backward teaching conditions also make students lack learning motivation. Research Conclusion Based on the national undergraduate curriculum construction standards, this paper creatively puts forward the “group progressive interaction” teaching mode of “freshman seminar“ by combining the OBE education concept with the effective education theory, and constructs a curriculum teaching system with the unity of temperature, height, breadth and effectiveness. “Freshman seminar” is a teaching system with temperature, height, breadth and effectiveness. It can not only effectively improve the teaching quality of the course, but also provide some references for the “freshman seminar” of different majors in the same university. We should fully understand the important position of group discussion in group emotional factors and actively improve the group's role psychological ability. We should pay special attention to its impact on life attitude and healthy behavior, and be a healthy self-manager, coordinator and collaborator. According to the psychological characteristics of these groups, we should actively and flexibly organize colorful activities, strive to create a relaxed and harmonious living atmosphere, create a friendly and mutually beneficial emotional artificial intelligence relationship, encourage and guide these groups, adjust their psychology to the best state, and promote the healthy development of their good cognition and life.

Economic Aspects of Models for Assessing Cybersecurity in Smart Cities

This publication is the result of UNIVERSITY RESEARCH PROJECT №NID NI-15/2018 “Economic aspects of models for assessing cybersecurity in smart cities”. The study presents, analyzes and compares the models of smart cities and the approaches to construction. A model for cybersecurity of smart cities is also shown. This model is built on an extended model of smart cities. The approach to the model is based on the specific vulnerabilities and threats for each of the modules. At this stage of the study, the link between the economic effects on cybersecurity begins. This link shows that investing in cybersecurity is accelerating digitalization. The next step of the study applies a critical analysis of the indicators traditionally used to assess cybersecurity. Criteria for selecting “good indicators” are proposed. The models for building cybersecurity are compared and their strengths and weaknesses are shown. These models can be applied in combination with project management for a cybersecurity model or a methodology for creating a model for economic assessment of cybersecurity. In support of the economic assessment model, the pragmatic security assessment methodology is applied. Information from various cases was used to support the project and a survey was conducted with users of the cybersecurity product.

Innovation Model of College Education Based on Nonlinear Random Matrix Organization and Management

At present, the scientific research and innovation team in colleges and universities has become an important carrier for the development of science and technology and personnel training in China, but in terms of its development status, the role of the scientific research and innovation team has not been really brought into play. Most colleges and universities only have the organizational form of scientific research and innovation teams. Too many scientific research tasks still rely on a small number of backbones. The cohesion of the team is not enough, and the combined force of the team is not manifested. In production practice, more and more high-dimensional data with dimension p approaching or even exceeding the number of samples n are collected and stored. Unlike traditional data analysis, high-dimensional data analysis is more complex and difficult. Layer of scientific research and innovation teams in colleges and universities is often ignored by managers, which is manifested by ignoring the cultural construction of the team. In the eyes of team managers, the time spent on building a team culture is far less than the time it takes to do a few more scientific experiments. University scientific research and innovation team is a multi-level network system. The asymptotic and nonasymptotic theories of random matrices break the framework of classical multivariate statistical analysis and are very suitable for the study of statistical characteristics of high-dimensional data, which can help machine learning algorithms to complete the analysis of high-dimensional data and expand its application range. The research and innovation team in colleges and universities is deeply analyzed from the perspective of nonlinearity. It is believed that the scientific research and innovation team in colleges and universities is a complex nonlinear system in terms of scientific research objects-interdisciplinary research, or from the perspective of personnel composition. Correspondingly, the construction should be considered from a nonlinear perspective in the process, following the systematic, integral, and multi-dimensional characteristics of nonlinear systems. Specifically applied to the construction of the team, first, from a macro perspective, three principles should be paid attention to at the beginning of the creation of the team, and then the specific application should be explained in detail. It is hoped that a new perspective will be put forward in the construction of scientific research innovation teams in colleges and universities to better promote the development of teams.

Analysis of the Turnover Tendency of College Teachers From the Perspective of Psychology.

University teachers are the core of university teaching and scientific research construction and an important link of double first-class construction. With the increasingly fierce academic competition among colleges and universities, the resignation behavior of college teachers is increasing, which has brought great impact on the construction of talents and discipline development in colleges and universities. The survey found that the departure of college teachers is not an isolated phenomenon, but a time-consuming process. Although the turnover tendency of college teachers has not evolved into resignation behavior in most cases, the resignation tendency of college teachers is always accompanied by negative psychology, complaints, and perfunctory work. These bad phenomena have brought double negative effects to colleges and universities and teachers themselves. According to this, psychological analysis of the turnover tendency of college teachers is conducive to building a benign flow mechanism for college teachers, thus supporting the long-term development of colleges and universities.

A Scientific Research Information System via Intelligent Blockchain Technology for the Applications in University Management

The scientific research information system plays an essential role in improving management efficiency and promoting technological innovation in universities. With the increasing computational demand for human-centric research management, blockchain technology, with distributed storage, consensus sharing, and security traceability, has efficiently assisted the research information system in dealing with various issues such as big-data scale, information security, interconnection, rapid response, and private security. A novel scientific information system framework based on intelligent blockchain technology is proposed to promote university scientific research’s information level and management efficiency. Moreover, four smart data contracts, including data collection, verification, sharing, and supervision, are custom-designed under an efficient scientific research information system. Those intelligent contracts provide reliable data security and traceability algorithms to guarantee the practical application of the scientific research information system. The results show that the constructed system can relieve the centralized storage pressure of scientific research information and solve the cross-subject sharing obstacle of massive safety data among different systems. Thereby, the system increases the transparency of scientific evaluation and realizes the credible supervision of scientific research information, which provides a way to promote the innovative application of blockchain technology in scientific research management in colleges and universities.

Under the new normal, the state and society put forward higher requirements for the efficiency and level of administrative services in universities. It is necessary to speed up the scientific, modern and professional construction of administrative teams in universities, carry out higher quality management and services in them, and provide comprehensive guarantee for teaching and scientific research in universities. This paper analyzes the current situation and problems in the construction of university administration team, discusses the effective path of the construction of university administration team, and promotes it from the aspects of system, mechanism, technology, mode and talent training, so as to comprehensively speed up the improvement and upgrading of university administration and service.

Silencing of NILCO by Small Interfering RNA Effects MDR1 in Colon Cancer Cells

The aim of the study is to investigate the effect of silencing of NILCO by siRNA on the MDR1 gene, which plays a role in chemoresistance. Cells of the human colon cancer lines Caco‐2 and HT‐29 were cultured at 37˚C in DMEM supplemented with 5% FBS in a humid incubator with 5% CO2. Exponentially growing untreated Caco‐2 and HT‐29 cells were collected and plated (4 x 105/ well in 2 mL) 24 hours before transfection. Plated cells were treated with either double‐stranded siRNA targeting Notch1 mRNA, leptin mRNA, IL‐1 β mRNA, control siRNA, or Paclitaxel (PTX) alone, Notch1 siRNA+PTX, Leptin siRNA+PTX, IL‐1β siRNA+PTX. The siRNAs of Notch1, IL‐1β and Leptin, were applied to the cells at a final concentration of 30 nM, and the cells were transfected with siRNA for 48 hours. After transfection, 100 nM Paclitaxel chemotherapeutic agent for HT‐29 and 130 nM for Caco‐2 was applied to the cells. Cells were harvested for PCR analysis after treatment with PTX for 24 hours.According to our findings, MDR1 gene expression was significantly increased in the paclitaxel group compared to the control group (p&lt;0.05). Silencing of Notch, leptin and IL‐1β decreased MDR1 gene expression compared with the control group, but it was not statistically significant. (p&gt;0.05). However, our results indicated that Notch1 siRNA+PTX, IL‐1β siRNA+PTX and Leptin siRNA+PTX downregulated MDR gene expression in the Caco‐2 cell line compared with PTX alone treated group (p&lt;0.01). In addition, MDR1 gene expression levels were significantly decreased in the Leptin siRNA+PTX and IL‐1β siRNA+PTX groups compared with PTX alone group in the HT‐29 cell line, but the decrease in the Notch1 siRNA+PTX group was not statistically significant. (p&lt;0.01, p&lt;0.05, p&gt;0.05). In conclusion, knockdown of NILCO genes is effective in regulating MDR1 expression, which is a hallmark in chemoresistance.The present study was supported by Eskisehir Osmangazi University Scientific Research Projects (BAP) Coordination Unit (grant no. 202011D11).

The Impact of Language Diversity on Knowledge Sharing Within International University Research Teams: Evidence From TED Project.

In today’s knowledge economy, knowledge and knowledge sharing are fundamental for organizations to achieve competitiveness and for individuals to strengthen their innovation capabilities. Knowledge sharing is a complex language-based activity; language affects how individuals communicate and relate. The growth in international collaborations and the increasing number of diverse teams affect knowledge sharing because individuals engage in daily knowledge activities in a language they are not native speakers. Understanding the challenges they face, and how they manage the emerging difficulties is the main aim of this manuscript. For this purpose, an explorative case study was conducted in an international university research project, namely the TED project. Both interviews and direct observations were employed to understand the phenomenon better and deliberately triangulate data and improve validity. Results show that non-native language use determines the emergence of different language proficiency, depending on the nature of the knowledge domain–job-related vs. non-job-related. Within non-job-related knowledge domains, the lack of linguistic abilities, summed to the perceived cultural diversities, mainly affects people’s propensity to engage in personal and more intense social relationships. Under such circumstances, tacit knowledge sharing is reduced with negative consequences on the project’s long-term innovative performance. Since the project is still running, detecting language challenges will allow the partners to design and apply effective measures to support cooperation with language and cultural barriers. Among them, code switching, adopted by “bridge” actors, already emerges as tool supporting communication and knowledge exchange.

The Use of Internet of Things and Cloud Computing Technology in the Performance Appraisal Management of Innovation Capability of University Scientific Research Team.

This study aims to speed up the progress of scientific research projects in colleges and universities, continuously improve the innovation ability of scientific research teams in colleges and universities, and optimize the current management methods of performance appraisal of college innovation ability. Firstly, the needs of the innovation performance evaluation system are analyzed, and the corresponding innovation performance evaluation index system of scientific research team is constructed. Secondly, the Internet of Things (IoT) combines the Field Programmable Gate Array (FPGA) to build an innovation capability performance appraisal management terminal. Thirdly, the lightweight deep network has been built into the innovation ability performance assessment management network of university scientific research teams, which relates to the innovation performance assessment index system of scientific research teams. Finally, the system performance is tested. The results show that the proposed method has different degrees of compression for MobileNet, which can significantly reduce the network computation and retain the original recognition ability. Models whose Floating-Point Operations (FLOPs) are reduced by 70% to 90% have 3.6 to 14.3 times fewer parameters. Under different pruning rates, the proposed model has higher model compression rate and recognition accuracy than other models. The results also show that the output of the results is closely related to the interests of the research team. The academic influence score of Team 1 is 0.17, which is the highest among the six groups in this experimental study, indicating that Team 1 has the most significant academic influence. These results provide certain data support and method reference for evaluating the innovation ability of scientific research teams in colleges and universities and contribute to the comprehensive development of efficient scientific research teams.

PASTE: FPGA-based Portable At-speed Scan Test Equipment

The increasing integration and complexity of chips driven by Moore’s Law has placed higher demands on chip verification and testing efforts. Automated Test Equipments (ATE) in conjunction with design for testability can effectively screen out faulty chips, but ATE is too costly and can be functionally redundant to be practical for small and medium-sized chip design companies and scientific research in universities. Therefore, in recent years, there has been a lot of research work on FPGA-based low-cost test equipment, but few studies have used the scan test method and have not been able to realize the at-speed test of the chip. In this paper, we propose a portable, low-cost and configurable FPGA-based chip scan test method, which can realize both normal and at-speed test, and can effectively filter the stuck-at faults and transition faults of the chip. We also optimize the test code size via run-length code compression algorithm and achieve a 68.16% compression rate for the test code, which effectively reduces the overall data storage and transmission overhead.
