In response to the significant rise of Home Health Care (HHC) due to technological advances, an expanding elderly demographic, and increased disease outbreaks—intensified by the COVID-19 pandemic—there is a pressing demand for better management of the resulting medical waste. This paper explores the development of a web-based decision support system designed to optimize medical waste collection in the HHC sector. The system is built using Flask for backend processes, with a user interface crafted from HTML and CSS, and employs JSON files for data management. It features dynamic routing enabled by two metaheuristic algorithms: the Strength Pareto Evolutionary Algorithm (SPEA-2) and the Non-Dominated Sorting Genetic Algorithm (NSGA-II). The application supports real-time adjustments to vehicle routes and waste production sites, enhancing the efficiency of medical waste management by minimizing human intervention. The design allows for easy adaptation to different sectors and can be expanded to test various scenarios. © 2024 by SCITEPRESS – Science and Technology Publications, Lda.

This paper presents the effectiveness of a fractional order PID (FOPID) controller in stabilizing a sensor mounted on a two-axis gimbal system used for tracking a target. The study focuses on isolating the sensor from various disturbance torques and body motions that can affect its line of sight. The analysis considers the impact of the base body's angular motion with dynamic balances on the gimbal system's torque relationships. The study uses a cross-coupling unit to link the stabilization loops for the gimbal system. Simulation comparisons demonstrate that proposed FOPID controller can outperform the conventional PID controller. © 2023 IEEE.

Dear editor,Robots are often conceived as human-like machines that can interact with humans naturally and safely. Human-robot interaction means that robots can communicate with people,understand their needs, and act accordingly [1]. This interaction is critical when two people are needed to finish a task cooperatively.

Navigating cluttered indoor environments presents a significant challenge for aerial robots, requiring agility, speed, and a high level of reliability to avoid collisions. This project aims to address this challenge by developing advanced algorithms for lightweight drones, enabling them to reach target location and carrying out delivery efficiently and safely. Utilizing camera data to map and avoid obstacles, we create a system that not only maps and perceives the environment but also navigates its path to the destination. Included in the educational content, this project demonstrates the effectiveness of the technology through practical applications and real-world testing, helping the next generation of engineers accumulate technical experience and broaden their understanding of drone navigation algorithms and applications in system integration. It has a milestone impact on education and development of the drone field. © 2024 IEEE.

Isotope effect on four-phonon interaction and lattice thermal transport: An atomistic study of lithium hydride

Physical Review B 2024年第20期110卷 205202页

Despite decades-long studies of how isotope-disorder scattering affects heat conduction, the effect of isotope-induced frequency shift on phonon-phonon interactions and lattice thermal transport remains largely unexplored and less understood. In this work, by using the phonon Boltzmann transport equation and machine-learning-assisted classical and path-integral molecular-dynamics simulations, we theoretically investigate the interplay between the intrinsic phonon-phonon scatterings and the isotopic compositions in lithium hydride (LiH). We reveal that the hydrogen isotopes notably impact thermal transport primarily via three-phonon interaction, while four-phonon scattering is less sensitive. Due to the stronger temperature dependence of higher-order processes, the isotope effect on thermal conductivity is increasingly suppressed by four-phonon scattering as temperature rises (from 73% to 35% at 700 K). In addition, we observe a more pronounced isotope effect on thermal diffusivity, which is attributed to the variation of heat capacity. Our work provides a promising avenue for manipulating thermal transport via isotope engineering, and it highlights the crucial role of four-phonon interaction.

This paper presents a vision of creating a more seamless sim-to-real robotic grasping and manipulation platform, bridging the gap between simulated environments and real-world applications. In recent years, the emergence of digital twin technology has revolutionized how we develop and test such applications. A digital twin can simulate the behavior of a physical system in a virtual replica of the real-world environment in real-time, enabling engineers and researchers to conduct detailed analysis and evaluation before deploying robotic systems in the real world. In this paper, we study the potential of creating a digital twin that allows researchers and engineers to seamlessly deploy a grasping system trained on synthetic data and tested in a simulation environment without writing any additional code or doing additional calibration. Using our proposed platform, we present a case study done using a robotic grasping algorithm and analyze the advantages and limitations of our current platform. In the end, we suggest some possible improvements and future directions to enhance the platform’s effectiveness and applicability. © 2024 SPIE. All rights reserved.

Individuals with Transfemoral Amputation (TFA) usually exhibit hip hiking walking with passive prostheses due to insufficient knee flexion. Powered knee prostheses can provide net-positive energy in the knee joint with improved gait symmetry. However, their effects on improving hip hiking are not well understood. This study investigates residual hip hiking through walking experiments using a robotic transfemoral prosthesis that can provide swing assistance. Different levels of assistive flexion torque were provided during the pre-swing and the mid-swing (no assistance, low assistance, medium assistance, high assistance). The kinematic and electromyographic (EMG) results indicate that with the increasing assistive torque level applied, the residual hip hiking was improved. The results preliminarily demonstrate the positive effect of knee flexion assistance on hip hiking improvement. © 2024 IEEE.

This paper presents the Design and Development of IoT Based Weather and Air Quality Monitoring stations that provide weather-related information for agriculture, and aviation climate forecasting purposes. The prototype is made up of an outdoor unit that consistently monitors numerous climatic variables such as temperature, humidity, barometric pressure, wind speed, wind direction, rainfall, and air quality using sensors with high accuracy. The air quality index(AQI) is also calculated using the sensors values which tell us whether the atmosphere is safe or polluted. ESP32(Microcontroller) which has a WiFi module is used to gather and send the sensor data through the Internet of things (IoT) to a ThingSpeak channel (IoT cloud), an internet platform where the data is saved, analyzed and read the data remotely. The weather station makes use of photovoltaic power and a rechargeable lead-acid battery to sustain the system. This paper also discusses the obvious strengths and shortcomings of the system and suggests plausible upgrades to assist the system in obtaining higher and long-term performance. © 2023 IEEE.
