Traditional medium access control (MAC) protocols, designed for more stable terrestrial environments, struggle to perform effectively in these circumstances. This paper evaluates the performance of UW-ALOHA-Q, a reinforcement learning (RL)-based MAC protocol designed for UASNs, focusing on its adaptability and performance in the face of the underwater channel’s inherent unreliability—an aspect not thoroughly examined in prior evaluations. Utilizing the DESERT Underwater simulator, we investigate the impact of channel conditions on the effectiveness of UW-ALOHA-Q’s learning mechanism. Our results show that UW-ALOHA-Q outperforms conventional protocols such as ALOHA-CS and TDMA in terms of channel utilization, but faces challenges in achieving convergence in highly unreliable channel conditions. Our study underscores the potential of RL-based MAC protocols in enhancing the robustness and efficiency of UASNs, while also identifying critical areas for further research in RL methodology to address the unique challenges of underwater environments.","PeriodicalId":518531,"journal":{"name":"2024 28th International Conference on Information Technology (IT)","volume":"11 16","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140527812","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}

A popular statistic for evaluating innovation between countries is the Global Innovation Index (GII), which provides a thorough analysis of the state of innovation worldwide. In this context, this paper aims to contribute to the literature by examining the multi-factoral effects of the innovation ecosystem on innovation development (internal causal effects), and the impact of global trends and crises on the innovation ecosystem (external causal effects) in Montenegro. The resources provided in this paper offer valuable insights into the innovation landscape in Montenegro and the Western Balkans, as well as the impact of globalization, global trends, and crises on innovation in the region. The paper also discusses the function of innovation hubs such as the DigNest project, in promoting cooperation between academic institutions, government agencies and corporations, and supporting the exchange of knowledge and fresh concepts.","PeriodicalId":518531,"journal":{"name":"2024 28th International Conference on Information Technology (IT)","volume":"39 2","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140527815","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}

Tartini tone, despite the fact that it is not present in the acoustic audio signal, is experienced as an audio sensation in the human consciousness, which is a consequence of the nonlinearity of the hearing system. In addition, some musical instruments, due to acoustic-mechanical nonlinearity, can reproduce Tartini tones when playing dyads. After that, as a measure of the intensity of Tartini tones, the Quadratic distortion coefficient $C_{2}$ is defined. In the second part of the paper, an experiment is described. In the experiment, the results of the analysis of Tartini tones on the copy of Antonius Stradivarius violin, are shown. A Base of test signal was formed, which was created from the dyads played on the tested violin (dyads from tones A4-E5 to A4 - G6#). Analysis of Tartini tones from the Base, in the spectral domain, was performed. The results of the analysis (Quadratic distortion coefficient $C_{2}$) are shown using graphics and tables. As an overall measure of the intensity of the Tartini tones, for the entire range of the violin (tones G3 – E6), the Mean quadratic distortion coefficient is defined. Finally, the results of the comparative analysis of Tartini tones on the tested violin and acoustic guitar CG 510 are presented.","PeriodicalId":518531,"journal":{"name":"2024 28th International Conference on Information Technology (IT)","volume":"101 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140527824","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}
