A Survey on IEEE 1588 Implementation for RISC-V Low-Power Embedded Devices
IEEE 1588, also known as the Precision Time Protocol (PTP), is a standard protocol for clock synchronization in distributed systems. While it is not architecture-specific, implementing IEEE 1588 on Reduced Instruction Set Computer-V (RISC-V) low-power embedded devices demands considering the system requirements and available resources. This paper explores various approaches and techniques to achieve accurate time synchronization in such instruments. The analysis covers software and hardware implementations, discussing each method’s challenges, benefits, and trade-offs. By examining the state-of-the-art in this field, this paper provides valuable insights and guidance for researchers and engineers working on time-critical applications in RISC-V-based embedded systems, aiding in selecting the most-suitable stack for their designs.This work was partially supported by the ECSEL Joint Undertaking in the H2020 project IMOCO4.E, grant agreement No.10100731, and by the Basque Government within the fund for research groups of the Basque University System IT1440-22 and KK-2023/00015
A Comprehensive Survey on Data Utility and Privacy: Taking Indian Healthcare System as a Potential Case Study
The authors would like to thank the anonymous reviewers and editors who
have been involved in examining this manuscript.Background: According to the renowned and Oscar award-winning American actor and film
director Marlon Brando, “privacy is not something that I am merely entitled to, it is an absolute
prerequisite.” Privacy threats and data breaches occur daily, and countries are mitigating the consequences
caused by privacy and data breaches. The Indian healthcare industry is one of the largest and
rapidly developing industry. Overall, healthcare management is changing from disease-centric into
patient-centric systems. Healthcare data analysis also plays a crucial role in healthcare management,
and the privacy of patient records must receive equal attention. Purpose: This paper mainly presents
the utility and privacy factors of the Indian healthcare data and discusses the utility aspect and privacy
problems concerning Indian healthcare systems. It defines policies that reform Indian healthcare
systems. The case study of the NITI Aayog report is presented to explain how reformation occurs
in Indian healthcare systems. Findings: It is found that there have been numerous research studies
conducted on Indian healthcare data across all dimensions; however, privacy problems in healthcare,
specifically in India, are caused by prevalent complacency, culture, politics, budget limitations, large
population, and existing infrastructures. This paper reviews the Indian healthcare system and the
applications that drive it. Additionally, the paper also maps that how privacy issues are happening
in every healthcare sector in India. Originality/Value: To understand these factors and gain insights,
understanding Indian healthcare systems first is crucial. To the best of our knowledge, we found
no recent papers that thoroughly reviewed the Indian healthcare system and its privacy issues.
The paper is original in terms of its overview of the healthcare system and privacy issues. Social
Implications: Privacy has been the most ignored part of the Indian healthcare system. With India
being a country with a population of 130 billion, much healthcare data are generated every day. The
chances of data breaches and other privacy violations on such sensitive data cannot be avoided as
they cause severe concerns for individuals. This paper segregates the healthcare system’s advances
and lists the privacy that needs to be addressed first
A Closer Look into Recent Video-based Learning Research: A Comprehensive Review of Video Characteristics, Tools, Technologies, and Learning Effectiveness
People increasingly use videos on the Web as a source for learning. To
support this way of learning, researchers and developers are continuously
developing tools, proposing guidelines, analyzing data, and conducting
experiments. However, it is still not clear what characteristics a video should
have to be an effective learning medium. In this paper, we present a
comprehensive review of 257 articles on video-based learning for the period
from 2016 to 2021. One of the aims of the review is to identify the video
characteristics that have been explored by previous work. Based on our
analysis, we suggest a taxonomy which organizes the video characteristics and
contextual aspects into eight categories: (1) audio features, (2) visual
features, (3) textual features, (4) instructor behavior, (5) learners
activities, (6) interactive features (quizzes, etc.), (7) production style, and
(8) instructional design. Also, we identify four representative research
directions: (1) proposals of tools to support video-based learning, (2) studies
with controlled experiments, (3) data analysis studies, and (4) proposals of
design guidelines for learning videos. We find that the most explored
characteristics are textual features followed by visual features, learner
activities, and interactive features. Text of transcripts, video frames, and
images (figures and illustrations) are most frequently used by tools that
support learning through videos. The learner activity is heavily explored
through log files in data analysis studies, and interactive features have been
frequently scrutinized in controlled experiments. We complement our review by
contrasting research findings that investigate the impact of video
characteristics on the learning effectiveness, report on tasks and technologies
used to develop tools that support learning, and summarize trends of design
guidelines to produce learning video
