AIP Conference Proceedings 2024年第1期3167卷

作者： Syamsudduha Syahrorini Salsabillah Jamaaluddin Jamaaluddin Arief Wisaksono Shazana Dyah Ayuni Agus Hayatal Electrical Engineering Study Program Faculty of Science and Technology Universitas Muhammadiyah Sidoarjo Sidoarjo Indonesia

This study aimed to develop a child supervision tool with a sound system to help parents quickly detect and locate danger to their children. The tool utilizes a Push Button or a microphone that, when activated by the child saying "Danger," sends the GPS coordinates to a NodeMCU ESP8266 microcontroller that sends location signals and notifications to the parent’s smartphone. The buzzer on the device also activates to alert the parent of danger. The study found that Voice Recognition as a sender of Blynk notifications and activating the buzzer function properly, and the GPS U-Blox Neo 6m accurately captured locations with an accuracy rate above 99%, with a sensor reading error rate below 0.1%. The implication is that this tool can help parents supervise their children and prevent them from becoming victims of kidnapping.

The use of the MathML language made possible to improve the accessibility of mathematics for blind or low-vision persons in digital media. Synthetic speech technologies have advanced significantly using MathML, however, the speech synthesizers' standard reading style is still not suitable for mathematics. Making mathematical reading of the speech synthesizers more natural and expressive is still a challenge. The creation of models to produce the appropriate prosody in the synthesized speech of math content is therefore necessary, as shown in previous research. This article presents a proposal for a model to improve prosody in the synthesized speech of mathematical expressions based on MathML. A corpus of mathematical expressions spoken by Mathematics teachers was created to support the model's development. The Fujisaki intonation model was adopted for intonation control, accent and phrase commands have been extracted from the corpus, and some adjustments have been made to manipulate prosodic parameters in the speech of mathematical expression in correlation with the MathML tree;additionally, a pattern of pauses control is being created. © 2020 ACM.

This paper describes an experimental study of SARS-CoV-2 detection using plasmonic gold nanoparticles, which overcomes the limitations of traditional detection techniques known for their time-consuming and a tendency to produce high false negative results. The transmission spectrum of gold nanoparticles (AuNPs) was recently estimated to be in filter-free wavelength sensors as a miniaturization detection system. Additionally, we demonstrate that wide-ranging absorption will manifest within the visible spectrum when the virus is partially coated with gold nanoparticles at a particular percentage of coverage. This extensive absorption can be harnessed to direct the advancement of a reliable and precise colorimetric plasmon sensor for the detection of COVID-19. The transmission value resulting from the gold nano seed is around 507–540 nm. In addition, plasmonic gold nanoparticles can detect SARS-CoV-2 well from the range of 100-1,000 ng/ml. We expect a miniaturization biosensor system with qualitative diagnosis to be realized by the development method.

This review synthesises advancements in natural convection within trapezoidal cavities using mono- and hybrid nanofluids, emphasising their geometric advantages for thermal management. Trapezoidal cavities promote asymmetric flow patterns that enhance heat transfer compared to conventional geometries, as demonstrated in applications like solar absorbers and electronic cooling. Through analysis of 50+ previous studies, the review identifies key trends: Hybrid nanofluids like Cu-Al₂O₃/water consistently outperform mono nanofluids in Nusselt number improvement, with gains exceeding 20 %. Inclined walls mitigate stagnant flow zones, though exact reduction rates vary with aspect ratio and nanoparticle concentration. Magnetic fields and porous media further modulate thermal performance, but trade-offs emerge between conductivity enhancement and viscosity penalties. This review provides a framework to optimise trapezoidal cavities with nanofluids for industrial deployment. © 2025 The Author(s)

A manipulator robot is a robot that has a mechanical system consisting of an arrangement of arms and joints that can produce controlled movements. A robotic arm usually consists of several joints including the base, shoulder, elbow, roll, gripper, and pitch of the gripper. Robot movement is generated from mathematical calculations performed in the controller. The motion of the manipulator robot follows a motion trajectory. The motion trajectory is made based on a collection of stop points and effectors. This study aims to create a robot motion trajectory design system using Lagrange interpolation. Lagrange interpolation is engineered to be embedded in precise microcontroller control systems. In this study, an Arduino Uno R3-based microcontroller was used as a data acquisition module. Prediction of the robotic arm's trajectory has been successfully made using Lagrange interpolation. The rise time is 15 seconds, the delay time is 12 seconds, the steady-state time and the peak time are 21 seconds. While the second experiment increased 9 seconds, 7 seconds of delay, steady-state time, and 13 seconds of peak time. Then for the third experiment, the rise time is 17 seconds, the delay time is 14 seconds, the steady-state time and the peak time are 22 seconds, the overshoot value and the steady-state error value is 0% where the output value produced is by the input value.

Application of biochar to landfill cover soils can purportedly improve methane (CH4) oxidation rates. However, understanding of the combined effects of soil texture, compaction, and biochar on activity and composition of the methanotrophs is limited. The amendment of wood biochar on two differently textured landfill cover soils at three compaction levels of the Proctor density were explored by analyzing changes in soil physical properties relevant to methane oxidation, the effects on CH4 oxidation rates and on the composition of the methanotrophic community. Loose soils with and without biochar were pre-incubated to equally elevate the CH4 oxidation rates. Hereafter, soils were compacted and re-incubated. Methane oxidation rates, gas diffusivity, water retention characteristics and pore size distribution were analyzed on the compacted soils. Abundance of methanotrophic bacteria (MOB) was determined at the end of both the pre-incubation tests and the incubation tests of the packed samples. Biochar significantly increased porosity at all compaction levels, resulting in enhanced diffusion coefficients. Also, a re-distribution in pore sizes was observed. Increased gas diffusivity from low compaction and amendment of biochar, however, did not reflect higher methane oxidation rates due to high diffusive oxygen fluxes over the limited height of the compacted soil specimens. All soils, with and without biochar, were strongly dominated by type II methanotrophs. In the sandy soil, biochar amendment strongly increased MOB abundance, which could be attributed to a corresponding increase in the abundance of Methylocystis species, while in the clayey soil no such response was observed. Compaction did not change the community composition in either soil. Biochar addition to landfill cover soils may not always enhance methanotrophic activity and hence reduce fugitive methane emissions with the effect being soil-specific. However, especially in finer and more compacted soils, biochar

The innovation of electric motorcycle swap-battery (EMSB) technology encourages the formation of a new ecosystem at the early stage of the supply chain. The EMSB technology has allowed an open innovation system with collaboration between supply-chain players, universities, and the government for finding a thriving solution to enable the faster adoption and diffusion of EMSB in Indonesia. Standardization is seen as a way to accelerate the downstream EMSB technology innovation to leverage the economic benefits and to support the growth of a green economy in Indonesia. This study aimed to propose a model with which to measure the technology readiness of the EMSB’s stakeholders in implementing the swappable battery (SB) standard. We developed the technometric framework and Economic Benefits of Standards—ISO Methodology 2.0. We generated 13 criteria of technoware, humanware, inforware, and orgaware and 21 indicators of the standard’s impacts to be utilized as a measurement model. We interviewed 11 respondents consisting of the standard regulator, research and development center, manufacturer, testing labs, and product-certification bodies. The results show the technology contribution coefficient (TCC) and earnings before interest and taxes (EBIT) value representing the SB standard’s feasibility. The proposed model can evaluate the weak points and propose strategies to leverage the SB standard’s technology readiness and economic benefits. © 2022 by the authors.

Speech brain-computer interfaces aim to decipher what a person is trying to say from neural activity alone, restoring communication to people with paralysis who have lost the ability to speak intelligibly. The Brain-to-Text Benchmark’24 and associated competition was created to foster the advancement of decoding algorithms that convert neural activity to text. Here, we summarize the lessons learned from the competition ending on June 1, 2024 (the top 4 entrants also presented their experiences in a recorded webinar). The largest improvements in accuracy were achieved using an ensembling approach, where the output of multiple independent decoders was merged using a fine-tuned large language model (an approach used by all 3 top entrants). Performance gains were also found by improving how the baseline recurrent neural network (RNN) model was trained, including by optimizing learning rate scheduling and by using a diphone training objective. Improving upon the model architecture itself proved more difficult, however, with attempts to use deep state space models or transformers not yet appearing to offer a benefit over the RNN baseline. The benchmark will remain open indefinitely to support further work towards increasing the accuracy of brain-to-text algorithms. © 2024, CC BY.
