Radio Frequency Identification (RFID) refers to a wireless system comprising two components: tags and readers. The reader is a device with one or more antennas that emit radio waves and receive signals from the RFID tag. This system is available on most systems applications especially involving security systems, including house/office access systems, toll systems, and library systems. The accessing data is made stand-alone or data-based through the existing conventional RFID system on the market, especially in library systems. Also, the tag provided is only limited to the same type, either cards or stickers. From that, it will produce problems in monitoring the status of books, especially for loans or returns. At the same time, the difference in detection sensitivity will be the effect of the detection range for the types of tag used. Through this research, the development of adaptive RFID on IoT platforms with different types of passive tag library systems highly emphasized monitoring the status of books besides maximum range detection by using different types of passive tag and at the same time increasing the security by implementing the book status detection on the gate of the library. The tag sticker used can be read/written in the 13.56 MHz frequency with the High Frequency (HF) band due to its affordability and ease of implementation. RFID tags are embedded in all books and activated; it triggers the alarm system if the status return gets captured on the memory of the RFID tag. The alarm accuracy is almost 100%. The result showed that within the acceptable range of 5 cm, the RFID reader works efficiently in detecting books. It shows that the card tag gives 90% sensitivity of range detection, followed by the sticker and keychain tag at 70%, and, lastly, the transparent card tags at 40%.

Published: October 2023

Contemporary youth culture has caused public parks to be used as locations for them to play Locative Augmented Reality Games (LARG). Nevertheless, the existing public parks were not designed for LARG, which requires wide space for youth to have rigorous physical activities and movement. Therefore, there is a need to integrate facilities for players of LARG in the development of future public parks. This research aims to evaluate the characteristics and components of public parks often chosen by youngsters to play locative augmented reality games and to recommend additional facilities to be integrated into future public parks for all-inclusiveness. This research uses Vlog and On-site observation to evaluate components of public parks. It also employs an open-ended questionnaire survey for collecting primary data on needed additional facilities for future public parks. For reason of Movement Control Order (MCO) during the Covid19 pandemic, the research could evaluate only three (3) public parks that are located in Kuala Lumpur, Malaysia. The finding shows that public parks need design improvement to integrate spaces and facilities for Locative Augmented Reality games players (LARG). The research implies that the function of public parks evolves based on demands from visitors. This research indicates that public parks should be designed to cater for digital recreational activities, triggered by contemporary youth culture and relevant to the digital future.

Published: October 2023

The issue of traffic congestion is one of the problems that disrupt the smoothness and comfort of the community in carrying out daily affairs. Rapid development, with an expanding population and vehicles in cities, has caused traffic congestion to become one of the most pressing concerns. As a result, this study proposed vehicle tracking method for traffic system management to improve and keep up with the rising demand for better traffic on the road. In the proposed system, cameras were placed at traffic intersections and along the road or highway to gather real-time traffic data. Image processing and machine learning algorithm were applied to calculate the number of vehicles based on the traffic flow and vehicle speed on the road to reflect the current traffic condition so that it helps general public to plan their trip and less pollution is produced in long run. This study focused on the cities of Cyberjaya, Putrajaya and selected Klang Valley areas to study the traffic condition during the peak and off-peak hour. Experimental results showed that the proposed machine learning solution provided high accuracy and effective detection on real-time traffic congestion. Current method used variables such as vehicle speed and number of vehicles to calculate the traffic flow on the road. As future direction, this method can be expanded to incorporate vehicle density as one of the variables for more precise traffic congestion reporting.

Graphene is a carbon allotrope composed of densely packed sp2-assembled carbon atoms in a honeycomb-like crystal lattice. It is widely used in various fields of materials science to develop sensors, optoelectronic devices, nanocomposites, and others due to its excellent electronic, mechanical, optical, and thermal properties. Graphene offers several advantages, including ease of fabrication, ultrafast recovery times, low fabrication cost, and low saturation intensities. Its unique zero bandgap property makes it the only material with wavelength-independent absorption, which is advantageous in generating pulsed lasers using saturable absorbers. This study investigates the performance of graphene with a chitin bio-host polymer as a saturable absorber in a 1.5 µm erbium-doped fibre laser. Graphene embedded in chitin was fabricated and utilized in a pulsed laser cavity operating in the wavelength region of 1.5 µm to enable Q-switched pulsed laser operation. The study achieved a pulse energy of approximately 19.83 nJ and a peak power of 10.72 mW. Increasing the pump power from 30.67 mW to 174.28 mW resulted in the highest repetition rate of 63.40 kHz, corresponding to the shortest pulse width of 1.74 µs. These findings have significant implications for applications requiring ultrafast precision and accuracy, such as medical laser equipment and flexible sensors.

Authors: Mercedes Bary Bigay
Published: October 2023

Pitt-Hopkins syndrome (PTHS) is a rare genetic disorder characterized by a molecular variant in the TCF4 gene involved in neuronal differentiation during embryonic development. Patients with PTHS present with syndromic facies, psychomotor retardation and intellectual disability. In addition, they may present with early-onset myopia, seizures, constipation, and episodes of hyperventilation and apnea. Some cases also meet criteria for autism spectrum disorder. In this article, we review the current literature on Pitt-Hopkins syndrome and present the first molecularly diagnosed case in the Dominican Republic. The patient in question exhibits typical facial features and a pattern of developmental delay consistent with PTHS. To date, no molecularly confirmed case of PTHS has been reported in the Dominican Republic, which makes this case an important contribution to scientific knowledge in the country.

Published: October 2023

Modulation classification (MC) is a critical task in wireless communication systems, enabling the identification of the modulation class in the received signals. In this paper, we analyzed a novel multi-layer convolutional neural network (CNN) to extract hierarchical features directly from the raw baseband samples. Moreover, we compared the training and testing accuracy of the CNN model for various decimation rates, input sample size and the number of convolutional layers. The results showed that the three-layer CNN model provided better classification accuracy with less computation cost. Furthermore, we observed that the MC performance of the proposed CNN model was better than the other deep learning (DL) and cumulant-based models.

Wear Failure of PEEK-Alumina Ball Bearings in Dry Rolling Contact at 600 rpm - Part 1: Effect of Failure due to Wear Damage on Friction Torque
Authors: Matsubayashi Soji , Watanabe Yukinojo , Kida Katsuyuki
Published: October 2023

The rolling contact fatigue of PEEK-alumina ball bearings in non-lubrication was tested under 500 N and 600 N. During the tests, the friction torque was measured. The retainers under both conditions broke during the tests, and rubbed on the upper and bottom races. The friction features were not different between 500 N and 600 N. However, the black colored surfaces on the races and retainer were identified only in the test under 600 N. The wear loss of the bearing tested under 600 N was larger than that under 500 N. From these results, the specimen under 600 N received the heavier wear damages than that under 500 N, and the worn surface was not related to the friction torque. The wear damages of the inner elements and the outer rings in the retainer were larger than those of the races and 9-alumina balls in both specimens.

Published: October 2023

Medications whose risk of adverse drug events exceeds their expected clinical benefit when given to older patients are called potentially inappropriate medications (PIMs). The geriatric population represents about 10% of the world population and 7% of the Indian population and consumes 40% of prescription and 35% of all over-the-counter drugs. That is why it is necessary to evaluate the use of PIMs in the geriatric population. This study aimed to evaluate prescriptions for PIMs by using three pre-validated and internationally used criteria, namely the Beers criteria (2019), the European Union (EU)(7) list (2015), and the PRISCUS list (2010). A retrospective observational study began after obtaining written approval from the institutional review board. Demographic and clinical profiles and patients' complete prescriptions were recorded, and the Beers criteria (2019), the EU(7) (2015) list, and the PRISCUS list (2010) were applied. A p<0.05 was considered statistically significant. A total of 345 patients, with a mean age of 71.48 years, were included in the study. Vitamin D3 (56.81%) was frequently prescribed as medicine. According to the Beers, EU(7), and PRISCUS criteria, PIMs were 311 (11.26%), 272 (9.85%), and 105 (3.80%), respectively. Pantoprazole [20.57% Beers and 23.52% EU(7)] and glimepiride [15.43% Beers and 17.64% EU(7)] were the most inappropriate drugs. According to the PRISCUS list, piroxicam (21.9%) and etoricoxib (19.04%) were the inappropriate drugs. According to the Beers, EU(7), and PRISCUS criteria, total inappropriate prescriptions containing at least one PIM are 183 (52.04%), 174 (50.43%), and 88 (25.5%), respectively. The number of prescriptions with inappropriate medication is highly correlated with the total number of drugs prescribed per prescription (p<0.01) and the total number of fixed-dose combinations (p<0.01). Maximum PIMs were found with the Beers criteria and minimum PIMs with the PRISCUS list. This study shows that the prescription of PIMs ranges from 25.5 to 52.04%. The EU(7) list had the highest sensitivity (63.66%), while the PRISCUS list had the highest specificity (98.48%) to detect PIMs with the Beers criteria taken as a reference.

Published: October 2023

INTRODUCTION: Particle filter based human motion video target tracking technology has become a trend. This project intends to apply particle filters to image processing of human activities. Firstly, an improved particle filter model is used to track moving video objects. The purpose is to further improve the tracking effect and increase the tracking accuracy. HSV distribution model was used to establish target observation model. The algorithm is combined with the weight reduction algorithm to realize the human motion trajectory detection in the target observation mode. The model was then confirmed by an examination of sports player videos. Experiments show that this method can be used to track people in moving images of sports. Compared with other methods, this method has higher computational accuracy and speed.

$\sigma $
-complete, then each positive weak* Dunford–Pettis operator
$T:E\rightarrow F$
is weakly compact if and only if one of the following assertions is valid: (a) the norms of

and F are order continuous; (b) E is reflexive; and (c) F is reflexive.
Asymptotic stability for the Dirac–Klein–Gordon system in two space dimensions
Authors: Dong Shijie , Wyatt Zoe
Published: October 2023

We study the Dirac–Klein–Gordon system in 1 + 2 spacetime dimensions. We show
global existence of solutions, as well as sharp time decay and linear scattering. One key advance
is that we provide the first asymptotic stability result for the Dirac–Klein–Gordon system in 1 +
2 spacetime dimensions in the case of a massive Klein–Gordon field and a massless Dirac field.
The nonlinearities are below critical in two spatial dimensions, and so our method requires the
identification of special structures within the system and novel weighted energy estimates. Another
key advance is that our proof allows us to weaken certain conditions on the nonlinear structures that
have been assumed in the literature.

Braverman and Kazhdan proposed a conjecture, later refined by Ngô and broadened to the framework of spherical varieties by Sakellaridis, that asserts that affine spherical varieties admit Schwartz spaces, Fourier transforms, and Poisson summation formulae. The first author in joint work with B. Liu and later the first two authors proved these conjectures for certain spherical varieties

As preparation for this result, we give explicit formulae for Fourier transforms on the affine closures of Braverman–Kazhdan spaces attached to maximal parabolic subgroups of split, simple, simply connected groups. These Fourier transforms are of independent interest, for example, from the point of view of analytic number theory.

Published: October 2023

Demonstrating higher-order thinking skills is crucial for thriving in a volatile, uncertain, complex, and ambiguous (VUCA) environment. In science education, inquiry-based learning has increasingly been recognized as a potent approach to stimulate students' higher-order thinking skills. While prior research has shown evidence of its positive impact on student achievement, no study has critically synthesized its effect on students' higher-order thinking skills in the context of science learning. Thus, this study conducted a meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. The study extracted twenty-six (26) effect sizes from twenty (20) studies, involving 1,349 students exposed to both inquiry-based and conventional approaches. Using the Comprehensive Meta-analysis Software, effect size (Hedges g) was calculated to determine the magnitude of the effectiveness of inquiry-based approaches. The overall weighted effect size of g = 0.893 demonstrates that inquiry-based approaches have a significantly large and positive impact on students' higher-order thinking skills. Moderator analysis suggests that regardless of students' educational level, scientific discipline, or level of inquiry, the use of the inquiry-based approach in teaching scientific concepts maximizes students' higher-order thinking skills. Although various inquiry-based approaches were effective when combined with other instructional strategies for teaching scientific concepts, only a few studies integrated technology into the implementation of inquiry-based approaches in science. Given the positive findings of this meta-analysis, science teachers are further encouraged to adapt inquiry-based approaches to enhance their teaching practices and support students in strengthening their higher-order thinking skills.

Although previous research on Virtual Reality (VR) demonstrated the effects of particular learning environment characteristics on learning, none of these studies constructed their virtual learning environment from a constructive alignment perspective. Therefore, this experimental study aims to investigate the impact of a constructively aligned virtual classroom setting, adopting an Artificial Intelligence (AI) training, on professionals’ knowledge on AI. This experimental condition was compared with a control condition, consisting of a similar constructively aligned AI-training within a traditional face-to-face setting. Learning outcomes were measured using a pre-test post-test validated multiple-choice test. Additionally, motivation and perceptions, which are considered as crucial intermediate variables, were assessed using questionnaires. Results revealed significant improvements in learning from pre-test to post-test with no statistical difference between the conditions. Following the principle of constructive alignment, professionals perceived the VR classroom environment as motivating as the traditional setting. As a result, professionals perceived the VR classroom setting to the same extent as the traditional learning environment. These findings reveal that improvements in learning outcomes of professionals can be realized if environments are designed based on the principle of constructive alignment irrespective of the VR or traditional settings.

Published: October 2023

The virtual learning environment (VLE) is of great importance in Higher Education as a repository for course content, communication and student support. Students’ satisfaction with the VLE may impact greatly on their engagement with the VLE itself, and, consequently, module content and learning more widely. In moving to a new VLE we wished to optimise its design for our students’ needs by determining features that impact students’ usage. As such, in this study we tested the satisfaction of psychology students with the layout used in our current VLE, Blackboard Learn (BbL). Using an online survey, students rated their satisfaction for each element of the BbL template on a 7-point Likert-type scale, from 1 (‘extremely dissatisfied)’ to 7 (‘extremely satisfied’). Eighty-seven students enrolled in the BSc Psychology (N = 68) and BSc Psychology (Sport, Health and Exercise) (N = 19) programmes completed the survey. Results showed that, overall, students were very satisfied with their BbL structure. Open-text comments indicated students appreciated the clear, organised structure, making it very easy to navigate. However, students suggested clearer labelling and greater consistency across modules would improve their learning. These findings will be used to inform the template of our new VLE.
Teachers’ Perceptions of STEAM Education

Published: October 2023

The support of academics, professionals, and researchers from the most diverse scientific areas to STEAM education is due to the strong impact it has on preparing citizens for a world of continuous scientific and technological development. Among its benefits, we highlight the improvement of critical, innovative, and creative thinking; the development of problem-solving, collaborative, cooperative, and communication skills; the gain of self-confidence, self-motivation, empathy, and resilience. However, the pace of implementation is not the same in all world regions. Developing and less developed countries have limitations of assorted nature in almost all areas of scientific-technological knowledge. With a consensus on the impact of STEAM Education on the progress of any society, its implementation in developing countries becomes fundamental and urgent. The study described here focuses on Cape Verdean teachers' perception of STEAM education and its integration into their pedagogical practices. It includes the analysis of data collected via a questionnaire adapted from one developed by the community for science education in Europe, SCIENTIX, and reported information on official documents. The findings reflect not only teachers' ideas and beliefs about STEAM education, but also their pedagogical approaches, the resources they (do not) use, and the obstacles they face.

The COVID-19 pandemic stimulated education system worldwide to employ online learning to support learning despite difficult times. To respond to this challenge and to promote Sustainable Development Goal (SDG) 4, advocating quality education, a virtual learning material (VLM) for Biology was articulated in Google Classroom. Accordingly, this study aimed to evaluate its acceptability and conformity to the international standards for online courses using the Open SUNY Course Quality Review (OSCQR) rubric as the questionnaire. Respondents (N=40) involved four stakeholders: Senior High School Students, Pre-service Science Teachers, High School Teachers, and Science Instructors/Professors, with n=10 representatives each group. Their perspectives of the VLM acceptability in terms of Overview and Information, Technology and Tool, Design and Layout, Content and Activities, Interaction, and Assessment and Feedback were obtained through a Google Form by rating the 50-item questionnaire on a 4-point Likert scale together with two open-ended questions. With a grand mean of 3.81(SD=0.40), the findings revealed highly acceptable results. The qualitative responses also substantiated this result. Significant differences in the responses are also discussed, while the Cronbach alpha reliability test is high (α=0.923). Significantly, the VLM conforms with the international standards for online course design, suggesting it can be implemented among target students.

Published: October 2023

Due to the important advantages of adhesive joints, such as their suitability for multi-material designs, their use has been increasing in the last decade. Determining the fracture behavior of structural adhesive bondings is essential for structural durability. In crack propagation analyses, adaptive meshing has drawn considerable attention because of its improvements in terms of complex preprocessing and time management. This paper presents a recently introduced separating morphing and adaptive remeshing technology (SMART) innovative crack growth simulation for adhesively bonded joints, considering static and cyclic cases. For the static case, an R-curve was obtained for the bonding joints of carbon steel and Araldite 2015. For the cyclic case, the Carbon Fiber Reinforced Polymer (CFRP) bonding joints were analyzed under constant-amplitude loading conditions. The crack-propagation rate and the number of cycles were estimated. Crack propagation simulations were validated using experimental data. Acceptable agreement was achieved between the experimental and estimated results.

The decision-making process related to maintenance in the power industry is traditionally associated with the fault detection process, mainly of capital equipment such as generators, transformers, etc. Complex multi-parameter remote monitoring systems, as well as modern maintenance theories and methodologies, have significantly improved this area through better fault prediction, real-time monitoring, lower maintenance costs, and more efficient operations. However, in addition to monitoring and fault detecting, it is very important to fault detection of the monitoring systems themselves. Identification of such failures is often very difficult because they can be "invisible" to the user, which can result in a wrong decision. The paper presents procedures and methods, based on the fuzzy logic system to support decision-making processes in remote monitoring and maintenance in hydropower plants. The following steps are listed: fault categorization, functional dependence between key parameters and development of fuzzy algorithms. A special place in the paper is occupied by defining the membership functions, their intervals, as well as the set of fuzzy rules obtained by experts. The paper presents a novel approach to the implementation and maintenance of complex monitoring systems.
