To improve system flexibility and reliability, mobile energy storage (MES) is treated as a unified dispatching resource of the active distribution network (ADN) to participate in operation optimization and power supply recovery. However, the coordinated optimization of MES with ADN network reconfiguration and voltage regulation is neglected in current studies. Especially, there exists blank research on ADN and MES as independent stakeholders. Therefore, a coordinated operation strategy based on the Stackelberg game for ADN and MES is proposed. Considering multitime period dynamic reconfiguration, voltage regulation, and their joint optimization with MES, the ADN as a leader, makes a tradeoff between expected profits and reliability to formulate reasonable prices for MES. As a follower, MES models energy transfer characteristics based on the space–time network and actively participates in the operation optimization of ADN by responding to the price decision to increase revenue. Following that, Karush–Kuhn–Tucker conditions are used to transform the two-layer optimization model based on the Stackelberg game into a single-layer mixed integer linear programming problem for solution. Finally, simulations on an improved IEEE-33 bus system validate the proposed strategy, which saves 2.2% of total social costs and reduces 6% of the voltage deviation. © 2005-2012 IEEE.

Quality monitoring and control for plasticization of acrylonitrile-butadiene-styrene regrind polymer in injection molding

引用

Polymer engineering and Science 2024年第3期64卷 1057-1070页

作者： Chen, Jian-Yu Wong, Liang-Ci Huang, Ming-Shyan Department of Mechanical Engineering National Kaohsiung University of Science and Technology Kaohsiung City Taiwan Department of Mechatronics Engineering National Kaohsiung University of Science and Technology Kaohsiung City Taiwan

To meet net-zero carbon emissions in injection molding, it is desirable to use regrind polymers in plastic parts fabrication. However, the quality of regrind polymer differs from virgin polymer due to the effects of temperature, pressure, and shear stress in the prior molding process. Consequently, the molded components differ in quality compared to those made from virgin material. This study investigates the feasibility of enhancing the quality consistency of regrind plastic components by controlling melt quality in plasticization. The evaluation of melt quality involves extracting two quality metrics from the pressure signal (i.e., the peak pressure and the pressure integral). They are then used to adjust the plasticization parameters as required to ensure that the weight and dimensions of the final regrind parts approach those of parts produced using virgin polymer. The experimental results show that the pressure integral effectively indicates the quality variation of the molded part during the injection molding of regrind polymer. Notably, by adjusting the back pressure, the quality of the molded part closely resembles that of the part made from virgin feedstock after six shots. © 2023 Society of Plastics Engineers.

Additive manufacturing offers a substantial reduction in lead times by enabling rapid design iterations, thereby accelerating the product development cycle. This method has been widely adopted across various sectors, including education, automotive, medical, aerospace, consumer electronics, and fashion. While this technology supports the recycling of PLA, reducing plastic waste, it faces challenges related to filament material failure and poor surface quality due to suboptimal process parameters. This study addresses these issues by focusing on the optimization of key process parameters—specifically, infill density, nozzle temperature, and print orientation—to enhance the mechanical properties of PLA. The Taguchi orthogonal array (L9) was utilized to design the experiments, with all samples produced in compliance with ASTM standards. The mechanical properties, including tensile strength, compression strength, and impact strength, were evaluated. Based on the results, the study identifies the optimal settings for infill density, nozzle temperature, and print orientation to achieve high-quality 3D printed PLA parts. In this study analyzes the surface quality and mechanical properties of PLA parts fabricated through FDM by using SEM techniques to evaluate 3D printing parameters. Tensile and compressive tests were conducted to examine the fracture behavior of components under different load conditions. Additionally, surface SEM images of the PLA parts were obtained to provide further insights. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2025.

The paper focuses on the analysis of the environmental impacts related to the production, operation, decommissioning of vehicles as well as servicing and repairs of cars in real conditions of their use. The authors’ presented mathematical model that was implemented in original numerical program EN-VEHICLE that enables the analysis of energy consumption and emission loads related to material inputs in the entire life cycle of a passenger car. It is a tool from the Life Cycle Assessment category that aims at the effective inclusion of environmental impacts in the decision-making process. The developed program allows for a quantitative interpretation of the calculation results in terms of the environmental safety in each of the phases and throughout the life cycle of the vehicle, taking into account the possibility of supplying the vehicle system with additional material streams derived from recycling and recovery, and introduced both during the construction phase and during the car operation phase. In the presented tool, linear algebra and matrix analysis were used in modeling the vehicle life cycle system. The results of the implementation of the mathematical model were presented in the form of a regression function that allows for approximation of selected empirical data. The regression analysis was used to verify the material characteristics. The tool can be used for a comprehensive comparative assessment of the environmental impact of a passenger car from different production periods. In addition, it can be used to forecast the environmental effects of changes in the material structure determining the production technology and, consequently, having a significant impact on the entire life cycle of the vehicle as well as energy and ecological parameters. © 2024 Warsaw University of technology.

In critical fire scenarios, experienced firefighters face significant risks that could be mitigated by employing fully autonomous firefighting robots equipped with multiple sensors. Our paper introduces such a robot, which utilizes flame sensors to detect fires and a pump with a water supply to extinguish them, an ultrasonic sensor enables obstacle avoidance during movement, while a gas sensor and buzzer provide alerts for gas leaks. The robot's mobility is ensured by wheel-attached gear motors connected through a motor driver, with all functionalities simultaneously controlled by an Arduino UNO R3 microcon-troller board. A key challenge was maintaining the overall cost of the basic prototype as low as possible, at approximately 25 USD. Our results demonstrate that the microcontroller board efficiently manages all these functionalities, swiftly detecting and extinguishing fires within the test environment, even in the presence of obstacles. The system detects fires within an average of 3 seconds and extinguishes them within 0-15 seconds, depending on the flame size. It also exhibits obstacle detection and avoidance capabilities with an average accuracy of 80-90 % in the test environment, ensuring precise navigation to the fire source and unobstructed fire suppression. Additionally, it promptly identifies gas leaks and activates the alarm system, outperforming many existing robots at this scale. © 2024 IEEE.

Mobile robots are yet at a young stage of development which is to be the future, these robots are expected to help humans with their work and be a companion. This paper presents the development of a Mobile robot equipped with a structure composed of aluminium strips and 3D printed mounts for coverings, servo motors for arm and shoulder movements, and DC encoder motors for base movements and rotation. The robot utilizes a camera mounted on its forehead for human detection and approaches individuals to greet them with a "namaste" gesture. The primary objective is to create a sequence control program and an Interactive GUI to enable the robot to detect humans and execute predefined actions based on the detected inputs. The GUI, developed using Python and the PyQt5 library, facilitates user interaction and provides additional information about the robot's functionality. Leveraging face detection algorithms and speech synthesis, the robot can engage in verbal communication with users. The code is implemented in Python, executed on a Raspberry Pi, which serves as the control unit for the robot's operations. © Grenze Scientific Society, 2024.

The battlefield environment is becoming increasingly complex, and traditional radio fuzes with single transmit waveforms are no longer effective in coping with the complex electromagnetic environment and jamming from fuze interferers. To address this issue, this paper proposes a design method for complex transmit waveforms. The algorithm is capable of cognitive processing of detection results, enabling the fuze to adaptively reconfigure its transmit waveform in the presence of jamming and environmental effects, thereby avoiding the impact of jamming and complex electromagnetic environments. Simulation and experimental results demonstrate that the algorithm possesses strong anti-jamming capabilities and can operate stably in complex electromagnetic environments. © 2024 IEEE.

Haptic devices are gaining significance in various fields such as medical applications, handling hazardous materials, and other robotics applications. The incorporation of force feedback is crucial in these systems, requiring a haptic device to enable users to sense the reactive forces between the slave robotic system and its environment. Bilateral control with force feedback is the predominant control strategy for the teleoperation of haptic devices. It is well known that kinematic analysis, including inverse kinematics and the Jacobian matrix, is essential for the control of haptic devices. The contribution of this paper is the kinematic analysis of the 5-ODF Haptic Wand from Quanser Consulting Inc. It presents the derivation of a closed-form solution for both forward and inverse kinematics, along with the Jacobian matrix. © 2024 IEEE.
