Modeling Cognitive System with Applied Machine learning in Additive Manufacturing using Fifth Generation Computer Systems

Data mining is known as data, which promotes the growth of knowledge discovery. It is the process of analyzing descriptive data from divergent perspectives and summarizing it into valuable information, which is high-level music processing out of which a machine intends to decipher the Raaga of a frequency or the pitch of the music. One of the ways to approach the task is by comparing selected music features from the spectrum and a Raaga database. Recognizing emotion from music has become one of the active research themes in image processing and applications based on human-computer interaction. This research conducts an experimental study on recognizing facial emotions. The flow of the emotion recognition system includes the basic process in the singular value decomposition system. These include music acquisition, pre-processing of a spectrum, feature detection, feature extraction, classification, and when the emotions are classified, the system assigns the particular user music according to his emotion. The proposed system focuses on live images taken from the music database. This research aims to develop an automatic music recognition system for innovative manufacturing through the additive manufacturing route. The emotions considered for the experiments include happiness, Sadness, Surprise, Fear, Disgust, and Anger that are universally accepted. This paper overviews the progress of applying Additive manufacturing in Applied Machine learning which sustains the capability of disruptive digital manufacturing.

AGE OF MUSIC ACQUISITION IMPACTS MEMORY FUNCTIONING IN OLDER ADULT MUSICIANS

Music playing is an involved activity, activating many areas of the brain and relying on integration of multiple cognitive processes simultaneously. Older adult musicians have been found to experience some cognitive benefits compared to non-musicians, seemingly related to their musical training. However, we still do not understand what factors of musical training may be driving these differences. The current study sought to isolate age of acquisition from “dose” of playing (i.e., amount of time spent playing) to explore music learning as a skill acquired during a sensitive period. Participants (n=48) were middle aged and older adults who self-reported on musical experiences, demographics, and underwent extensive neuropsychological assessment of all major domains. The sample was divided into Early Age of Acquisition (≤9 years old), Late Age of Acquisition (>9), and Non-Musicians. Results showed that musicians who began formal training at the age of 9 or younger, had significantly higher scores on tests of verbal memory (California Verbal Learning Test – II: Immediate Recall – p = 0.04, partial η2 = 0.14, Short-Delay Free Recall - p = 0.03, partial η2 = 0.16, Long-Delay Free Recall - p = 0.03, partial η2 = 0.15). Results are discussed in the context of a sensitive period for acquiring musical education, and implications of these results on cognitive aging.

Review of Literature: Pedagogical Content Knowledge and String Teacher Preparation

In the past few decades, there has been an increase in the percentage of non-string specialists teaching string classes. In this article, we review literature about subject-specific pedagogical content knowledge (PCK) in general and music education settings, to better understand the challenges that teachers with limited knowledge of string-specific content may face when teaching strings students. Included in this review are discussions concerning trends in the string teacher workforce, PCK in education and music, acquisition of PCK in general settings and music teacher preparation programs, and relationships between teacher content knowledge and instructional effectiveness, both in general and string education settings. Based on this review, we recommend that preservice and professional development curricula for music teachers include comprehensive preparation in both content-specific and pedagogical-specific knowledge for teaching strings.

Music and Ideology: Musical School in Rezekne after World War II

The aim of the article is to reflect the processes and problems of musical education renewal, which the teachers of Rezekne Secondary Music School faced under the circumstances of sovietisation, by evaluating to what extent the old elite (pre-war elite of National Conservatory) could adapt to the new circumstances and to what extent it was allowed by the regime. The article is based on the historical analysis of a discourse by evaluating the texts of documents available in the archives and identifying the dominant circumstances under which they have been created. In order to evaluate the principles of ideology influence and formation of social reality, the author compares the texts of the documents and conclusions found there with the opinions of representatives from various scientific areas on the features of musical life in that period of time. During the research, the author established that, on the one hand, the external factors and those, which are subjected to ideology, characterize the activity of the school; however, on the other hand, there are also the internal, as well as determined and retained factors of traditional requirements of music acquisition.

The ties that bind? Online musicians and their fans

Purpose – The purpose of this study is to examine the relationships between musician’s social network sites (SNS), the tie that fans may develop via these sites, and music acquisition, via legal and illegal means. Design/methodology/approach – A quantitative approach was taken, gathering 352 responses from young adults via an online survey. Findings – Perceptions of interactivity and sincerity on musicians’ SNS are found to lead to stronger ties, enhancing the fan’s feeling of closeness to the musician, the fan’s inclination to spread positive word-of-mouth, and the time a fan spends on the site. Pathways are found between the fan activity, sense of closeness and time spent on the SNS. In terms of acquisition, the tie strength indicator of time spent on the SNS holds a positive relationship with purchase intent. While a sense of closeness holds a negative relationship to illegal downloading activity, the fan’s activity recommending the musician has a positive influence on illegal downloading. Research limitations/implications – Limitations of this study include a limited amount of information on the musician and extent of fandom, suggesting future research to tease out the effects of SNS on fans with varying levels of existing commitment to musicians. Practical implications – Stronger ties between fans and musicians may be developed via interactive and sincere SNS. Activities which encourage the fan to give recommendations and spread positive word-of-mouth are especially influential in driving purchase intent. Originality/value – These results provide theoretical and practical implications in relation to how SNS may influence the online fan-celebrity “tie” and music acquisition – three elements which have not to date been examined.
