This paper compares video and audio QoE of OFDMA multi-user transmission and reliable groupcast over wireless LAN. We assume video and audio transmission to several terminals simultaneously. As a reliable groupcast method, we employ Unsolicited Retry, a technique of IEEE 802.11aa GroupCast with Retries. We utilize IEEE 802.11ax for OFDMA transmission. We evaluate application-level QoS by computer simulation. We then assess QoE through a subjective experiment with video and audio streams generated by the output timing obtained from the simulation. We notice that each method has a situation to be applied appropriately.

In this paper, we consider multi-view video and audio streaming using MPEG-DASH, which enables to transmit video tailored to the network conditions over HTTP communication. This paper uses HTTP/2 instead of HTTP/1.1, which the authors previously used. HTTP/2 manages a series of request-response exchanges called a stream, which is assigned a unique stream ID. We perform a subjective experiment under various network conditions to evaluate application-level QoS and QoE. From the evaluation results, we investigate the effect of the HTTP/2 stream on the video and audio quality of the users in the multi-view video transmission scenario.

Digital transformation in various industries has led to considerable changes in organizational strategic behavior. Micro, small, and medium enterprises (MSMEs) in the global sense, have been under pressure to adopt information and communication technology to increase their performance. Digital marketing has started to be recognized as one potential enabler of digital transformation. Managerial practices and academic literature provide limited guidance on how digital marketing can be used as an enabler of digital transformation across enterprises. This is especially in dearth among the study of MSMEs, particularly in emerging countries such as Indonesia where MSMEs have significant major roles in economic growth and workforce absorption. Besides, only a small portion of Indonesian MSMEs has embraced digital technology. Using the case study method, this paper finds that digital marketing adoption of the MSMEs may serve as the first-level enabler of digital transformation by allowing the MSMEs to enhance its dynamic capabilities. This paper contributes to the area of digital transformation through a marketing perspective, something that is novel in the context of MSMEs. For managers, the results of the study provide actionable guidelines for the MSMEs on how to drive digital transformation with digital marketing as the entry-level of adoption.

This paper considers multi-view video and audio transmission on ICN (Information-Centric Networking)/CCN (Content-Centric Networking). Routers in ICN/CCN can cache content. Besides, the capacity of routers' caches is finite, so various cache control schemes have been proposed to improve cache efficiency. This paper presents and evaluates a new and suitable control scheme for multi-view video and audio transmission. For this purpose, we construct a network environment with Cefore. We assess application-level QoS (Quality of Service) and QoE (Quality of Experience). We then show the effectiveness of the proposed control scheme.

One of the biggest challenges in Music Information Retrieval (MIR) is classification. MIR is a subset of Machine Learning (ML), where the methods found in computerscience can be used to solve problems in the music domain area. Indonesia is an archipelago country inhabited by around 1,340 ethnic groups spread across 38 provinces. This ethnic group has a variety of cultures, including folk songs, and almost every area in Indonesia has folk songs. In this study, we conducted a regional classification of 500 Indonesian folk songs from 10 regions in Indonesia. We build a model for regional classification tasks using the MIR approach. This model combines feature selection and dimension reduction capabilities. By using hyperparameter tunning and a cross- validation of 5 folds, the result of our proposed model for regional classification of Indonesian folk songs using K-NN with PCC-LDA can obtain an accuracy rate of 84.7%.
