Bowing Detection for Erhu Learners Using YOLO Deep Learning Techniques

The traditional ways to learn musical instruments are having lessons with teachers, or self-paced by teaching videos and books. Nowadays, the musical instrument self-learning systems are in the ascendant. However, it is difficult for a musical instrument learner to know if his playing posture is correct unless the teacher provides guidance in person and corrects it immediately. Due to the breakthrough development of computer vision technology, computers with camera lenses can act as teachers’ eyes to detect the learners’ movements and give some assistance for their self-learning. Erhu, a kind of Chinese traditional stringed instrument, is getting popular worldwide. In this research, taking the erhu bowing method as an example, we use YOLO object detection technology to track the trajectory of the bow in the video and evaluate whether it meets the level and straightness requirements. For the purpose, we first define the measurement methods of level and straightness and design a system to record the progress. In 2016, Joseph Redmon et al. proposed a real-time object detection method called YOLO, “You Only Look Once”. The multi-layer CNN architecture is executed only once, which greatly improves the detection speed. To track the movement of erhu’s bow, we must at least detect the coordinates of two objects, the erhu bow and the right hand of the player who holding the bow. Our images data set to train the object detection model came from several Chinese music society in Taiwan. The experimental results show that the model can successfully mark the desired objects. Finally, the study found that even senior erhu players still have some deviations, but they are more stable than beginners. Self-correction through system prompts would help learners to reduce the bias problem.
Research on the New Eco-construction of College English Teaching in the Data Age

Along with the in-depth application of computer and network technology in the field of education, the concept and strategy of College English teaching is quietly undergoing a major change. The era of big data has brought a new perspective and direction to college English teaching reform. Under the development trend of continuous integration of education and digital technology, College English teachers need to build a new ecology of College English based on the era of data, explore a hybrid teaching model by breaking the time and space constraints, reconstruct the evaluation mode of education quality by applying data mining and develop teaching team building by changing self-role. In this way, a systematic, open, dynamic and three-dimensional College English curriculum system can be established to better meet the needs of college students getting high-quality and diversified college English teaching, and to meet the requirements of national economic and social development for talent training.
Driving Product Sales Performance by Analysing Product Prelaunch in A Linguistics Approach

This paper uses a natural linguistics analytic approach, by studying product prelaunch events' script, to investigate the determinants of driving the product sales based on customer values framework as well as "Nextopia" consumer psychology.This research contributes to the theoretical framework of identifying the customer values, which have impacts on the product sales.Moreover, we investigate how product sales be driven by the optimism attitude and affective forecasting feeling, which are vocal during product prelease events.Through the study of analysing the essential words, which represent the underlying customer values from the script of Apple Inc. product prelaunch events, we found that product functional and experiential/ hedonic of customer values drive product sales.Induced affective forecasting message negatively moderated the impact of cost/ sacrifices values on product sales.In addition to the theoretical contributions, this research provides practical guidelines of how to shape the product prelaunch speech to maximize the sales of the to-be-released products.
Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. By using flux data from a newly installed eddy covariance (EC) flux tower in southern Kenya and high-resolution Sentinel-2 satellite data, the aims of this thesis were to i) determine the net C flux and climatic factors governing GPP at a high-intensively cropped dryland farm, ii) use the dataset to test different remote sensing driven GPP models and the MOD17 GPP product (collection 6), and iii) assess the difference in annual GPP among croplands and shrublands, grasslands and open forests. Results: The studied cropland had a net ecosystem exchange (NEE) of 170 g C m-2 between March and December 2019, thus acting as a source of C during the measurement period. Climatic factors governing GPP were vapour pressure deficit (VPD), soil moisture and air temperature (Tair). Using the 2-band enhanced vegetation index (EVI2), VPD and Tair as input in a multiple linear regression yielded the best results to in situ GPP (R2=0.65, RMSE = 2.02 g C m-2 d-1). Croplands had a higher mean annual GPP compared to grasslands, shrublands and open forest in the sub-humid to semi-arid agro-climatic zone, and a similar annual GPP to open forest in the semi-arid agro-climatic zones. The studied field at the Ausquest farm had however a considerably lower GPP compared to both natural lands and other croplands. Conclusion: Based on these results, land cover changes occurring over the vast savannah landscape in southern Kenya are not likely to reduce GPP in the region, however, more data is needed to make a more robust assessment. The studied cropland at the Ausquest farm emitted considerable amounts of C during the measurement period, indicating the importance of accounting for respiration in land-cover change studies. The ambiguity of the GPP models can be attributed to the persistent cloud cover during the growing season, as well as difficulties in accounting for the influence of anthropogenic effects on GPP, and to little ground-based data for calibration and validation.

The Greenland Geodetic Network (GNET)

&amp;lt;p&amp;gt;The Greenland Geodetic Network (GNET) consists of 58 global navigation satellite systems (GNSS) installed on the bedrock around the perimeter of the island. Much of the network was installed between 2007 and 2009, providing a long time series of GNSS data for much of Greenland. The network is currently owned and maintained by the Danish Agency for Data Supply and Efficiency (SDFE), while the National Science Foundation (NSF) provides support for data transport from the deep field. Here, we present a new resource (go-gnet.org) intended to be a clearinghouse to foster international collaborations and to encourage new and innovative use of these data.&amp;lt;/p&amp;gt;

EFFECT OF EXPERIENTIAL LEARNING STRATEGY ON BIOLOGY STUDENTS’ ACADEMIC ACHIEVEMENT IN DUTSIN-MA LOCAL GOVERNMENT AREA OF KATSINA STATE

This study investigated the effect of experiential learning strategy on biology students’ academic achievement in Dutsin-Ma L.G.A. of Katsina State. The study employed a quasi-experimental research design. The population for the study comprised 718 Senior Secondary II biology students. Simple random sampling technique was used in selecting two schools in Dutsin-Ma LGA. Two intact classes were selected from the two schools. One intact class represented the experimental group (N=38) while the other intact class represented the control group (N=31.)The experimental group was taught using experiential Learning Strategy while the control group was exposed to traditional lecture method of teaching. The instrument for data collection was Biology Achievement Test (BAT) validated by experts with reliability coefficient of 0.63. The data was analyzed using mean, standard deviation and t-test. The result revealed that the Experiential Learning Strategy is superior to the traditional Lecture method in facilitating student’s achievement in biology. The study also revealed that males showed higher achievement than females, and the difference in the mean achievement was statistically significant. The researcher recommended that experiential Learning strategy be adopted in senior secondary schools because it enhances academic achievement.

SCIENTIFIC AND METHODICAL BASIS FOR EVALUATION OF DESIGN COMPETENCIES OF FUTURE ENGINEERS

The urgency of the problem is explained by the growing importance of the methodological activities of high school teachers in the training of highly qualified, competitive personnel (qualified engineers) in the higher education system in the context of multi-level education. The goal-oriented approach to learning outcomes. The implementation of a competency-based approach has raised the question of the relevance of higher education teachers to innovative processes of methodological education. This article is devoted to the causes of methodological ability as a key component of the methodological activity of a university teacher, which directly affects the quality of education, characterizing his level of professionalism. The leading approach from the scientific jihad of this paper is modeling, which allows the problem to be viewed by teachers as a process of purposeful and conscious mastery of certain specific competencies in order to carry out highly qualified methodological activities.
“Review On Revocable-Storage Identity-Based Encryption on Cloud Data Security Authentication And Data Sharing”

Cryptography or cryptology is the practice and study of techniques for secure communication in the presence of third parties called adversaries[2]. Cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics, intelligence and more—over the Internet (“the cloud”) to offer faster innovation, flexible resources and economies of scale.  But there exists a natural resistance for users to directly outsource the shared data to the cloud server since the data often contain valuable information. Thus, it is necessary to place cryptographically enhanced access control on the shared data. Identity-based encryption is a promising cryptographical primitive to build a practical data sharing system. However, access control is not static. That is, when some user’s authorization is expired, there should be a mechanism that can remove him/her from the system[11]. Consequently, the revoked user cannot access both the previously and subsequently shared data. To this end, we propose a notion called revocable-storage identity-based encryption (RS-IBE), which can provide the forward/backward security of cipher text by introducing the functionalities of user revocation and cipher text update simultaneously.
Avaliação de documentos arquivísticos: teoria e metodologia

This article is the result of a research that aims to confront four theoretical and methodological proposals for archival appraisal. Schellenberg's model is the first model of great international impact, standing out for the elaboration of the so-called “value theory”. The second model, the Documentation Strategy, consists of a plan to preserve documents from different sources, but which refer to the same task, activity, or area. The third model, the Documental Plan, has the strategy of building a list of relevant historical events, based on which the documents are appraised. The macro-appraisal, on the other hand, proposes to appraisal first the functions and activities of the producer, considering the relations between society and the State. The analysis of these models allowed us to understand that there is not exactly a contrast between a modern and postmodern archival theory regarding document evaluation. The arguments presented by the different authors do not allow to identify rupture. These models are historically contextualized and answer questions from their respective contexts, without, however, necessarily denying the model developed in the middle of the 20th century by Schellenberg, even though this denial appears in the speech of one or the other.

Klinik penulisan karya ilmiah yang telah diadakan menghasilkan satu artikel yang siap publikasi melalui jurnal dan tiga artikel yang masih dalam tahap penyelesaian. Hasil ini diharapkan mampu memicu semangat para guru untuk menghasilkan karya ilmiah. Pada dasarnya guru sangat antusias selama mengikuti kegiatan klinik penulisan karya ilmiah, namun kesibukan tugas di sekolah masih menjadi kendala utama dalam menyelesaikan penulisan karya ilmiah. Abstract: This scientific writing clinic aims to assist teachers in overcoming difficulties in writing and publishing scientific papers. The results of the survey and discussion with the Head of MGMP Physics at Lumajang Regency High School showed that there were still many teachers who had difficulties in conducting scientific publications. The inhibiting factors in scientific publications experienced by teachers include the lack of mastery of ICT, the willingness and ability to write, and the rush of work to be done. Scientific writing clinics are held with two face-to-face activities and four independent activities. The scientific writing clinic consists of 16 hours of independent activities and 16 hours of face-to-face activities. Writing scientific clinics that have been held produce one article that is ready for publication through journals and three articles that are still in the stage of completion. This result is expected to trigger the enthusiasm of the teachers to produce scientific work. Basically the teacher was very enthusiastic during participating in clinical writing activities, but the busy work in school was still a major obstacle in completing writing scientific papers.
The Borel-Cantelli Lemmas, and Their Relationship to Limit Superior and Limit Inferior of Sets (or, Can a Monkey Really Type Hamlet?)

The purpose of this chapter is to show that if a monkey types infinitely, Shakespeare’s Hamlet and any other works one may wish to add to the list will each be typed, not once, not twice, but infinitely often with a probability of 1. This dramatic fact is a simple consequence of the Borel-Cantelli lemma and will come as no surprise to anyone who has taken a graduate-level course in Probability. The proof of this result, however, is quite accessible to anyone who has but a rudimentary understanding of the concept of independence, together with the notion of limit superior and limit inferior of a sequence of sets.

Current Status and Challenges of Korean Middle School Dokdo Education

Dokdo is our own territory that was captured by Japan during the Russo-Japanese War and reclaimed after independence. However, Japan continues to insist on sovereignty over Dokdo by publishing “Takeshima- Day” and publishing “Teaching Instructions” that marked Dokdo as Japanese territory and textbooks. In addition, recently, even in Korea, the authors of the so-called <Anti-Japanese Religion> led by professors of famous universities have been blatantly claiming that Dokdo is Japanese territory. Even in order to actively respond to this false claim to Japan's claim to Dokdo and the misrecognition of history by some intellectuals in Korea, who are embracing the logic of the Japanese right-wing, Dokdo education at the school site is very important. In particular, it is necessary to educate teenagers who will lead the future society that Dokdo is not just a sovereignty issue, but a matter of past history in Korea and Japan. In this sense, rethinking how to teach and learn Dokdo at the current school site is meaningful for resolving conflicts with Japan over Dokdo and developing the capacity for democratic citizens for our students who need to live as members of the international community. do. Based on this problem recognition, we examine the composition and system of the middle school curriculum and textbooks related to Dokdo, and then review how Dokdo education is being conducted in the middle school according to the Dokdo education policy of the Ministry of Education and the Metropolitan/Do Office of Education. I would like to make some educational suggestions and suggestions. However, it has not progressed to what extent Dokdo's educational activities at school sites have changed students' history and territorial views, and whether they can effectively respond to the Japanese aggression of Dokdo. I intend to leave this part as a research project in the future.

PERCEIVED LECTURERS FEEDBACK AND ONLINE LEARNING STUDENTS SATISFACTION: A CASE STUDY OF UNITAR COLLEGE STUDENTS

Online learning is a relatively ongoing word used to delineate a type of learning that can be performed through websites. The importance of online learning development and its implementation is undeniable especially in todays world since the attacks and outbreaks of COVID-19 virus. Hence, this study was conducted to examine the determining factor of perceived lecturers feedback towards online learning students satisfaction in one of the private colleges in Malaysia, applying the quantitative method. A total of fifty-three (53) students from UNITAR College have participated in the questionnaire survey utilising questionnaires that were adapted from previous works. Data were analysed using SPSS version 23 for descriptive assessment and Smart-PLS 3.0 for both measurement and structural model analysis. Findings revealed that perceived lecturers feedback has a significant relationship with UNITAR College online learning students satisfaction (T-value =7.102; P-value =0.000). By understanding the factor that leads to students satisfaction on online learning, it is hoped that all lecturers from colleges and universities would provide timely and constructive feedback to students to ensure the online learning effectiveness.

This classroom action research was conducted in two cycles which consists of five components; design, implementation, observation, evaluation, and reflection. The subjects of this study were teacher and VIII C. Observation, test, and questionnaire were the collection technique. The data were analyzed qualitatively and quantitatively. It was found that; (1) students’ competence is improved after experiential learning model was implemented, it can be seen from the initial reflection which showed that the students’ average score is 65. Their average score in cycle I is 74.3. Their average score in cycle 2 is 86. Those have achieved the minimum completeness criterion, 75. (2) The learning steps of implementing the experiential learning are introduction, content, and conclusion. (3) The students’ response is improved in every cycle. In cycle I, students’ responses are 1243 with average 43 positive categories. In cycle II, the responses have increased into 1410 with average 49 very positive categories. Thus, experiential learning model can improve students’ competence in writing poem. It is suggested that; (1) Indonesian language teacher or other teacher can use this learning model as guidance in teaching; and (2) other researchers can conduct a continuation research related to experiential learning model.
Data mining and compression : where to apply it and what are the effects?

In data mining it is important for any transforms made to trainingdata to be replicated on evaluation or deployment data. If theyis not, the model may perform poorly or be unable to accept theinput. Lossy data compression has other considerations, however,for example it may not be known whether or not lossy compressionwill be applied to deployment data, or if a variable compressionratio is to be used. Furthermore, lossy data compression typicallyreduces noise, which may not affect or even improve model performances, and performing feature selection on lossy data mayfind better features than selecting from the original data. In thispaper, we investigate the effects of selecting features, learning, andmaking predictions from data that has been compressed using lossytransforms. Using vehicle telemetry data, we determine where inthe data mining methodology lossy compression is detrimentalor beneficial, and how it should be compressed. We also proposea specialised feature selection approach that considers predictiveperformance alongside compressibility, measured by compressingthem either individually or in a single concatenated stream
