Enhancing Astronomical Literacy In Maritime Navigation: Impact Of Social Media and Citizen Science

This study investigates the influence of social media and citizen science initiatives on astronomical literacy and its application in maritime navigation among transportation cadets. Through qualitative research methods, including interviews and observational studies, the perceptions and practices of 40 cadets at a transportation institute in Jakarta were explored. The findings reveal that social media platforms play a significant role in enhancing navigational knowledge and skills among cadets, providing access to diverse educational resources and fostering engagement with astronomical content. Similarly, participation in citizen science projects positively impacts astronomical literacy, offering hands-on learning experiences that reinforce theoretical knowledge. Moreover, the research highlights the importance of promoting cultural competence in maritime education to prepare cadets for navigating in multicultural environments. By aligning educational curricula with international standards and embracing emerging technologies, educational institutions can better equip transportation cadets with the necessary skills and knowledge to succeed in the globalised maritime industry

Perceptions Of Cadets On Visual Cues And Astronomical Learning In Maritime Safety And Navigation

This research explores the perceptions of 40 cadets at the Transportation Institute in Jakarta regarding the application of visual cues and astronomical learning in maritime safety and navigation. Through qualitative research methods, including interviews and observational techniques, the study examines cadets' proficiency in celestial navigation, their engagement with social media and citizen science initiatives related to astronomical learning, and their awareness of cultural differences in navigation practices. The findings reveal that cadets demonstrate a high level of proficiency in celestial navigation, indicating the effectiveness of the educational practices at the Transportation Institute. However, there is room for improvement in terms of leveraging social media for educational purposes and developing cross-cultural sensitivity among cadets. The research highlights the importance of integrating practical training, fostering cross-cultural competence, and promoting a culture of lifelong learning among cadets to ensure their preparedness for the modern maritime industry. The insights gained from this research can inform educational practices and professional development initiatives in the maritime sector

Visual-Inertial Odometry on Chip: An Algorithm-and-Hardware Co-design Approach

Autonomous navigation of miniaturized robots (e.g., nano/pico aerial vehicles) is currently a grand challenge for robotics research, due to the need of processing a large amount of sensor data (e.g., camera frames) with limited on-board computational resources. In this paper we focus on the design of a visual-inertial odometry (VIO) system in which the robot estimates its ego-motion (and a landmark-based map) from on- board camera and IMU data. We argue that scaling down VIO to miniaturized platforms (without sacrificing performance) requires a paradigm shift in the design of perception algorithms, and we advocate a co-design approach in which algorithmic and hardware design choices are tightly coupled. Our contribution is four-fold. First, we discuss the VIO co-design problem, in which one tries to attain a desired resource-performance trade-off, by making suitable design choices (in terms of hardware, algorithms, implementation, and parameters). Second, we characterize the design space, by discussing how a relevant set of design choices affects the resource-performance trade-off in VIO. Third, we provide a systematic experiment-driven way to explore the design space, towards a design that meets the desired trade-off. Fourth, we demonstrate the result of the co-design process by providing a VIO implementation on specialized hardware and showing that such implementation has the same accuracy and speed of a desktop implementation, while requiring a fraction of the power.United States.
