This study is based on a large dataset consisting of school students grades for 2020 academic year taken from “Electronic education in Tatarstan Republic” system. The analysis is based on the use of machine learning methods and feature importance technique realized by using Python programming language. One of the priorities of this work is to identify the academic factors causing the most sensitive impact on school students’ performance. In this work we used the Shapley values method for solving this task. This method is widely used for the feature importance estimation task and can evaluate impact of every studied feature on the output of machine learning models. The study-related conditional factors include characteristics of teachers, types and kinds of educational organization, area of their location and subjects for which marks were obtained.","PeriodicalId":237333,"journal":{"name":"3C TIC: Cuadernos de desarrollo aplicados a las TIC","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130338167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The majority of the writer-generated material requires the usage of text mining algorithms and sentiment analysis, even if this information is meant to be instructive. Sentiment Analysis is a technique in Natural Language Processing (NLP) that tries to identify and extract assessments communicated within a given text.

The multiple access strategy is one of the highly used methods for allocating the range of users in cellular network. Spectrum allocation is a crucial element to take into account since cellular communication is becoming more and more popular. NOMA is a channel access mechanism used in 5G mobile communication. It is also known as non-orthogonal multiple access. NOMA is a potential strategy for enhancing spectral efficiency and sum rate. Using the NOMA method, we evaluated the BER versus transmitted power of two users in rayleigh and nakagami fading channels. In this NOMA setup, a single antenna is shared by two users. Two users can accept the same frequency using 5G NOMA technology, but at different power levels. The results of the MATLAB simulation show that the two user NOMA in the Nakagami channel performs better than the Rayleigh channel in terms of Bit Error Rate vs. Transmitted Power.","PeriodicalId":237333,"journal":{"name":"3C TIC: Cuadernos de desarrollo aplicados a las TIC","volume":"188 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114431334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Re-identification is the act of identifying someone in photos or videos acquired from other cameras after they have already been recognized in an image or video from one camera. Re-identification, which involves generating consistent labelling between several cameras, or even just one camera, is required to reconnect missing or interrupted tracks. In addition to surveillance, it may be used in forensics, multimedia, and robotics.Re-identification of the person is a difficult problem since their look fluctuates across many cameras with visual ambiguity and spatiotemporal uncertainty. These issues can be largely caused by inadequate video feeds or lowresolution photos that are full of unnecessary facts and prevent re-identification. The geographical or temporal restrictions of the challenge are difficult to capture. The computer vision research community has given the problem a lot of attention because of how widely used and valuable it is. In this article, we look at the issue of human re-identification and discuss some viable approaches.","PeriodicalId":237333,"journal":{"name":"3C TIC: Cuadernos de desarrollo aplicados a las TIC","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116545442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El objetivo es demostrar que la técnica puede ser desempeñada con el clarinete utilizando las TIC. Se puso en práctica la técnica en 13 clarinetistas con el Título de Grado Profesional o cursando estudios superiores. Estos la estudiaron mediante 29 ejercicios tras realizar una primera grabación de 2 ejercicios. Tras 8 semanas de estudio se realizó la última grabación para ver si la calidad de la técnica era mayor. La implementación de las TIC consistió en el uso de Audacity (para grabar), Sibelius7 (para escribir los ejercicios), ZyMi (para grabaciones y estudio) y los espectrogramas en Sonic Visualiser de los audios pregrabados (para valorar si existe evolución de la calidad del doble picado). Una vez que fueron analizados los espectrogramas y se escucharon las grabaciones en Sonic Visualiser, se observó que en la primera grabación la calidad del doble picado fue bastante deficiente en los registros agudo y sobreagudo de muchos de los participantes. Sin embargo, en la última grabación todos ellos consiguieron realizar los dos ejercicios con gran calidad en todos los registros. Como conclusión, puede decirse que el doble picado puede ser ejecutado por cualquier clarinetista y que, para ello, es muy recomendable la utilización de las TIC. La utilización de ZyMi y Sonic Visualiser permitió ver en los espectrogramas si la ejecución era precisa en cuanto a tempo, calidad del sonido, articulación, duración e igualdad de las notas.","PeriodicalId":237333,"journal":{"name":"3C TIC: Cuadernos de desarrollo aplicados a las TIC","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114830166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
