A Real-Time VSLAM Based on Deep Features and Object Detection for Dynamic Environments

The current simultaneous localization and mapping (SLAM) relies heavily on the hypothesis of static environments, and the localization accuracy and stability of the algorithm will be extremely affected when facing dynamic and complex environment. In response to this problem, a real-time visual SLAM system for dynamic environments is presented in this work, based on the ORB-SLAM3 algorithm for improvement. After obtaining the RGB images, the features are first extracted by the GCNv2 neural network, while the semantic information about the images is initially obtained using the lightweight target detection network YOLOv5. Then, based on the dynamic characteristics of the object between consecutive frames, the static feature points are obtained by eliminating its dynamic features to complete the pose estimation. The proposed algorithm is validated using the publicly available TUM dataset, and the experimental results show that the root mean square error of absolute trajectory error is reduced to 93.96% and 33.3% compared with ORB-SLAM3 and DS-SLAM, which improves the localization accuracy in dynamic scenes and also ensures the real-time performance of the system.
The technical principle and application case analysis of logistics UAV

Driven by multiple factors such as the sharp increase in distribution demand, soaring labor costs, and complex service scenarios, Unmanned Aerial Vehicles (UAVs) have met the basic requirements for practicality and jointly contributed to a "change" in logistics innovation —logistics UAVs. Logistics UAV is one of the typical representatives of the logistics industry's development towards automation and intelligence. After studying two representative logistics and transportation companies in the industry, it was found that the two companies have different positionings for the application scenarios of their respective logistics UAVs, but they have both developed Industry-leading products and technologies through long-term research and development. Although major companies have invested a lot in logistics UAVs in recent years, there are still four major technical problems to be overcome: path planning, automatic obstacle avoidance, battery life and safety. In addition to unavoidable technical problems, factors that hinder the large-scale deployment of logistics UAVs include imperfect commercial markets and imperfect regulatory systems. Although there is still a long way to go for logistics UAVs, logistics UAVs will surely become an indispensable infrastructure for the modern logistics industry in the future, helping the logistics industry to achieve leapfrog development.
From DAO to TAO: Finding The Essence of Decentralization

Decentralized Autonomous Organizations (DAOs) have been gaining popularity in recent years due to their promise of realizing the decentralized Web 3.0. However, most DAOs rely heavily on token-centric value systems as well as allocate decision-making authority and yield-sharing rights according to the held tokens, which often lead to monopolization of power and rights. To address this issue, this paper contributes to propose a truly democratic organization model, named True Autonomous Organizations and Operations (TAOs), that does not count upon tokens and is guided by principles of contribution-based and on-demand allocation. We first discuss the design of TAOs, including their infrastructures, power structures, and value systems, and then provide a technical roadmap for implementing TAOs in the DeSci context. This research can provide a valuable guidance for the construction and application of TAOs.
Elementary School Students: A Practical Situation Analysis of an Ethnomathematics Learning Mobile Application

This study aimed to analyze elementary school students’ didactical situation in traditional games using a mathematics learning mobile application. This study analyzed the traditional games of endog-endogan, engklek , and congklak , which originate from the Sundanese culture in West Java, Indonesia. This qualitative study used a didactic research design involving 524 students. In the learning obstacle stage, 304 students in grades 1-6 of elementary school participated. In the initial didactic stage, 152 students from grades 1-6 of elementary school were involved, while in the revised design stage, another 152 students from grades 1–6 elementary school were involved. The instruments employed in these stages were the obstacle learning test, worksheet, documentation, and observation. The study findings revealed that the subjects experienced learning obstacles in epistemology on addition, subtraction, integers, and fractions. Through the initial didactic design process and revision, a mobile ethnomathematics learning teaching material application was developed with optimal endog-endogan and engklek games, with almost all teachers’ predictions being the same as elementary school students’ responses. Hence, mobile applications featuring traditional games can serve as a viable alternative to facilitate the acquisition of mathematical knowledge, making the learning process more accessible and adaptable to the topics studied. This combination of mobile applications with traditional games in teaching fills the gap in the lack of potential research on ethnomathematics learning in elementary schools. Keywords: mobile application, ethnomathematics, traditional games, elementary school students. DOI: https://doi.org/10.55463/hkjss.issn.1021-3619.62.49
Importance of Lift-the-Flap Book Development as a Learning Medium for Culture-Based Self-Protection

Every year, child sexual abuse (CSA) cases worsen. The development of learning media should be designed using the right content, media, and resources. This study aims to discover the importance of developing Lift-the-Flap book as a book series to introduce self-protection based on culture. This study used the ADDIE instructional design model with a qualitative research method. The analysis was performed using MAXQDA software. The research participants were 37 people consisting of kindergarten (TK) and Raudhatul Athfal (RA) teachers and parents. Data were obtained through in-depth interviews with the participants. The results showed the characteristics of teacher and parent participants: the development of lift-the-flap book is worth trying because the teacher does not know how to Lift-the-Flap book; teachers’ ways to teach self-protection, and implement culture-based self-protection. The study also revealed child sexual education learning media and barriers to child sexual education implementation. Keywords : development, sexual education, learning media, early childhood.

Catalyzing University English Learning using Multimodal Mobile Apps

This study aimed to investigate and evaluate the effectiveness of a multimodal mobile application in enhancing English language proficiency, increasing motivation, and mitigating technical difficulties among students at Universitas Borneo Tarakan. The novelty of this research lies in its pioneering exploration of the use of multimodal mobile apps to catalyze university-level English learning. This research area has seen limited investigation until now. By implementing a research and development (R&amp;D) methodology, the study designed, developed, and tested an app tailored to the specific needs identified through a comprehensive student survey. This innovative approach provided detailed insights into the impact on student learning outcomes, marking a significant contribution to the rapidly evolving field of technology-enhanced language education research. English proficiency scores improved from 65 to 82 out of 100, motivation levels increased from 2.8 to 4.1 on a five-point scale, and technical problems significantly decreased following the implementation of the program. These findings suggest that multimodal mobile applications could effectively catalyze English learning while addressing common digital learning challenges. However, the study also underscores the need for further research in a broader range of educational settings to generalize these results and explore other influential factors, such as teaching methods or study time. Keywords: multimodal mobile application, English proficiency, motivation levels, technical difficulties, technology-enhanced language. https://doi.org/10.55463/issn.1674-2974.50.12.7

Choosing Digital Tools in Educational Scenarios: A Case Study with In-Service Teachers

This paper examines the choices of digital tools made over traditional ones by 18 Greek teachers of foreign language, humanities, and arts, in educational scenarios during in-service blended training on script design. Each trainee submitted four scenarios and was free to select his/her own tools. Hierarchical cluster analysis performed on the participants, showed two groups, with the first group ending up with decreasing use of digital tools, whereas the other group exhibited a progressive increase, with constructive and collaborative categories being more popular. All disciplines increased the usage of communicative tools. Teachers of Humanities usually employ projections and Art teachers use more physical objects. Teachers of foreign languages tend to the fewest digital tools in every scenario. All trainees used more multidisciplinary tools than specialized ones; the latter was mostly applied by Art teachers. The research findings shed light on the trends revealed by teachers’ choices and enrich the knowledge base about the planning repertoires and logic of in-service teachers.
Magic Numbers In Computers: Exploring Their Uses And Importance

The phrase, “Not everything that can be counted counts, and not everything that counts can be counted” by Albert Einstein and the recommendation, “We should have a humble reverence for everything that we shall never measure” by Vaclav Havel reveals the fact that numbers never tell the whole story, in information or in any other context and also it never prevents from seeking for numbers, magic or otherwise, which capture the structures and patterns of the information world. Numbers have their own significance and it can be observed that they play a vital role in different aspects of the world viz. numerology, thus it takes the title of “magic”. The concept of magic numbers has its roots in various branches of science, including physics, chemistry, and mathematics. The notion of magic numbers showcases the interdisciplinary nature of the concept, connecting various scientific disciplines through a common thread of special, often symmetric or highly stable numerical values. This research paper investigates the concept of magic numbers in computing, specifically focusing on their applications across various domains within the field. In computing, magic numbers refer to specific numerical values embedded in data structures that play a crucial role in file formats, network protocols, and various software applications. The paper defines magic numbers, examines the historical evolution of magic numbers in computing, investigates their theoretical underpinnings, and explores how they are practically applied in tasks such as file identification, network protocol and software development.

Jakarta COVID-19 Forecast with Bayesian PIRD Multiwave Model

Governments have to consider both socioeconomic and health conditions in handling the COVID-19 pandemic. To help them in understanding possible scenarios behind the numbers and deciding optimum policy, this study proposed a Bayesian protected-infected-recovered-dead (PIRD) multi-wave model. Compounds of the Richards curve are used to understand how many pandemic waves possibly occur, how significant is the occurrence of every single wave, and dynamic in every single wave. The model also estimated the mortality rate due to the COVID-19 pandemic and the duration between infection to death, also infection to recovery. We fitted Jakarta’s COVID-19 data from 3 March 2020 to 25 November 2021 with help of OpenBUGS. We learned that their pandemic should consist of at least two waves, expected to have three waves already. By letting social restriction be looser together with decreasing number of new infection cases, Jakarta could have its fourth and even fifth pandemic wave that starts around mid-May to mid-July 2022 and reach its peak around January to February 2023. Vice versa, they could enter the endemic phase around the end of August 2022 until the beginning of February 2023 and finally have zero COVID-19 new infection around mid-January until mid-June 2023 by having stricter social restrictions.

Mobile Ubiquitous Learning is the Need of the Hour for English Language Teaching during COVID-19 Pandemic

"All people naturally want to know" is how one of the world's greatest thinkers, Aristotle, begins his well-known book Metaphysics (65). Humans are recognised to possess a wide range of potential skills in the modern day. Among these skills, knowledge, learning, and curiosity surface during a person's growth and take shape under the impact of their surroundings. Our understanding comes from the realm of sensations. In the same book, Aristotle discusses the value of the senses and offers the proverb, "Who loses a sense loses a world” (68). He stresses the value of the senses to learn by noting that they are vital for comprehending the cosmos and what is happening. He stresses the use of the senses to learn by stating that "science is based on the senses, but senses are not science," noting that "the senses are an important aid in understanding the universe and what is happening" but also acknowledging that "the senses can be misleading from time to time” (70).
Research on the dynamics of transitional regimes in an inertial screen with two motor vibrators

Purpose. Analysis of mathematical models of vibrating screens, using the theory of oscillations and mathematical modeling to study the impact of initial start-up parameters and the dynamics of transient processes on the operation of the screen. Methodology. This research is dedicated to the analysis of mathematical models that describe the startup process and subsequent operation of a vibratory screen. Methods of oscillation theory, system dynamics, and mathematical modeling are applied to analyze the vibratory processes of screens. Special attention is given to studying the impact of initial startup parameters on the operation of the screen, including amplitude, frequency, and phase of oscillations. Within the framework of this work, detailed graphs are constructed that reflect the displacement of different points of the structure, as well as the trajectories of their movement during operation, using the Mathcad software. Results. Transitional modes of startup and steady operation are analyzed, with motion dynamics equations for both phases detailed. Displacement graphs for key screen points over time and changes in screen movement across operational modes are highlighted. Scientific novelty. The study defines a mathematical model for the motion of a screen with two motor-vibrators during startup and steady operation. It introduces a graph showing the screen points' displacement over time, from startup to steady mode, and illustrates the trajectories of these points under various operational modes. This research advances material classification techniques, enhancing process optimization and equipment efficiency. Practical significance. This research enhances vibratory material sorting by analyzing screen dynamics across operating modes, leading to optimized workflows, lower energy use, and improved sorting efficiency. It also bolsters equipment reliability and reduces the risk of failures, cutting down on maintenance and repair expenses.
UNCOVERING THE MULTIDIMENSIONAL PERCEPTUAL SPACE OF LOW BIT-RATE MULTI-CHANNEL AUDIO CODECS

A pilot study 1 was conducted to investigate the perceptual importance of selected fidelity attributes (timbral fidelity, frontal spatial fidelity, and surround spatial fidelity) and their contributions to the basic audio quality (BAQ) of low bit-rate surround sound codecs.The results obtained from this experiment showed a high correlation between the fidelity attributes assessed.This was explained by the fact that the quality impairments caused by low bit-rate multichannel audio codecs are not perceptually orthogonal (independent).Several coding artefacts are affected at the same time, such as a lack of high frequencies and a reduction of the original spatial image.This led to an investigation to discover whether independent dimensions describing the perceived quality of low bit-rate multichannel coding systems could be found.Multidimensional scaling (MDS) also known as 'perceptual mapping' was the first method chosen to perform this study.The rationale for this choice was that other researchers had successfully used MDS to determine the perceptual dimensions of multiple audio stimuli.The outcomes of this study are presented in this paper along with a detailed description and interpretation of the dimensions uncovered.
FINITE ELEMENT ANALYSIS OF VIOLIN SHELL MODES

Over the last few years there has been a dramatic increase in the number of acoustic measurements on outstanding Cremonese violins.However, there is still no consensus on the relationship between their acoustical properties and perceived quality.Of particular note have been the modal analysis measurements of George Bissinger 1,2 at the University of East Carolina, which now includes results from the recent 3D laser-scanning project undertaken in collaboration with two leading American violin makers, Joe Curtin and Sam Zygmuntowicz, and Fan Tao of D'Arradio Strings.This project has produced detailed 3-D information of the vibrations and associated acoustic radiation of the 1715 Titian and 1734 Willemotte Stradivari and 1735 Plowden Guarneri del Gesu violins.In addition, there are now a large number of admittance and acoustic radiation measurements on more than a dozen Stradivari and Guarneri violins and other fine Cremonese and modern instruments -and a few "bad" instruments for comparison.All such measurements confirm the acoustic importance of the low frequency "signature" modes: the A0 air resonance at ~ 280Hz, the CBR centre bout rotation mode at ~ 350-450 Hz, and the two strongly radiating B1-and B1+, often referred to as "corpus bending" modes, at typical frequencies in the range 370 -450Hz and 520-580Hz respectively.These modes determine the strength of the first and second partials of all bowed note sounds below the open E-string, and must therefore be important in determining the perceived quality, though the amplitudes of partials at higher frequencies are equally important in assessing quality across the whole playing range.The primary objective of the present proposal is to develop a FEA model of the violin, with fully adjustable parameters -like plate thicknesses, elastic properties and arching, sound post properties and position, rib thicknesses and heights, bridge geometry and resonances, f-hole shape and elastic properties of the central island area, bass bar size, etc -to address violin maker's frequent questions on how such parameters affect the position and strength of the easily measured signature modes and perceived quality of an instrument.A second objective is to achieve a better understanding of the origin and nature of the CBR, B1-and B1+ modes than currently exists.
