Enhancing disaster awareness and preparedness is crucial for building resilient societies. This study comprehensively assessed the levels of disaster awareness and preparedness among children and adults in Thailand through qualitative and quantitative surveys. Children strongly emphasized the importance of disaster education in school curricula, leveraging multimedia channels for risk communication, and implementing early warning systems. In contrast, adults exhibited a greater understanding of the significance of business continuity and disaster management technologies. These findings revealed disparities in disaster awareness across age groups. The insights from this study suggest age-specific engineering system approaches to information dissemination, contributing to the development of inclusive disaster preparedness strategies that incorporate diverse stakeholder perspectives. Children highlighted the need for practical training on survival skills, accessible disaster communication through SMS alerts, and monitoring systems for timely information dissemination. Adults, on the other hand, placed greater importance on business continuity planning and recognized the usefulness of technologies like satellite imagery for disaster management. By identifying these gaps and areas for improvement, this research provides valuable guidance for tailoring interventions, fostering a culture of preparedness, and harnessing technological solutions that resonate with the needs and concerns of different age cohorts within Thai society. © 2024 IEEE.

There is an urgent need to develop next-generation rechargeable batteries for a carbon-neutral society. In this context, our research team is focusing on magnesium, which is abundant in the earth's crust and inexpensive. Ribbons of Mg-9%Al-3%Ca, a magnesium alloy, were prepared as anode material for rechargeable batteries by a single-roll rapid solidification method. The fabricated ribbons were subjected to various manufacturing conditions, and various properties such as surface properties, microstructure, mechanical properties, and electrochemical activity of the fabricated ribbons were evaluated. As a result, it was found that a peripheral speed of 25 m/s and an injection pressure of 0.05 MPa or less were desirable to fabricate ribbons with good surface and mechanical properties. It was also confirmed that electrochemical activity contributes significantly to the orientation of magnesium and that production conditions with a peripheral velocity of 30 m/s or higher resulted in low electrochemical activity. © 2024 The Japan Institute of Light Metals.

The authors have studied a method for describing the behavior of haptic communication under communication delay by using difference differential equations and determining stability by the roots of the characteristic equation. This paper firstly introduces the outline of this method. Furthermore, we found that this method can be applied to determine the stability of consensus control of multiple terminals under communication delay or systems that simulate diffusion equations with a large number of communication nodes operating autonomously and decentralized. This paper reports the above results. © 2023 IEEE.

Cellulosic ethanol has been gaining high attention due to its potential to reduce the greenhouse gas emission and cut down the world dependence on fossil fuels. Biorefinery approach for cellulosic ethanol has advantages due to its non-food competing status, natural abundance and benefit to decrease the combustion of agricultural wastes after harvesting seasons. Due to the recalcitrant structure of lignocellulose biomass, pretreatment and hydrolysis are critical to determine the economic viability of the process because they influence the conversion rate of fermentable sugars and, subsequently, final product i.e. ethanol. Therefore, the design for the process to compromise fermentation and upstream process is also essential. With all constraints exist when using harsh conditions during pretreatment, the recombinant engineered microorganisms have been developed and applied as biocatalysts during fermentation. To achieve the maximum production efficiency, different strategies of recombinant engineered microbes include expression optimization to modify the metabolic pathway, modification of secretion and transportation routes, improvement of stress tolerance, and utilization of both C5 and C6 sugars. This review provides the development and current status of cellulosic ethanol production via biorefining process by genetic engineered microbes with a focus on the technological aspects. The remaining challenges, perspective, and economical feasibility of the process are also discussed. © 2024 Tamkang University. All rights reserved.

In this paper, a novel framework for real-time localization through pre-built map update by 3D LiDAR mounted on a robot is proposed. Autonomous mobile robots usually use high-precision 3D maps (i.e., HD maps) built in advance. However, as time passes, the environmental map changes from the actual environment, adversely affecting autonomous navigation. In addition, it is costly to recreate an HD map every time the environment changes. Therefore, it is necessary to update environmental maps simply and frequently. We propose a method for real-time map updating in the form of point clouds and validate the results of integrating map update with localization. © 2025 IEEE.

A Low Cost Triple-Node-Upset Self-Recoverable Latch Design for Nanoscale CMOS

引用

IEEE Transactions on Device and Materials Reliability 2025年第2期25卷 296-307页

作者： Bai, Na Zhang, Pengshuai Xu, Yaohua Guo, Yunhui Li, Hang Wang, Yi Wen, Xiaoqing Anhui University Information Materials and Intelligent Sensing Laboratory of Anhui Province Anhui Hefei230601 China National University of Defense Technology College of Computers Hunan Changsha410073 China Kyushu Institute of Technology Graduate School of Computer Science and Systems Engineering Fukuoka8208502 Japan

Due to the constant reduction of semiconductor feature sizes, the charge sharing effect is getting worse. The occurrence probability of triple-node upset (TNU), which has a significant impact on the circuit’s reliability, is rising in nanoscale digital circuits. This paper proposes a low overhead and TNU self-recovery latch (TNU-SR) based on the 28 nm CMOS technology to efficiently tolerate TNU and reduce the power dissipation and latency of the latch. The latch design proposed in this article adopts stacked transistors to reduce sensitive nodes and area overhead. The TNU-SR latch uses clock gating and high-speed transfer path technology, resulting in low power dissipation and low delay. For simulation results, compared with existing latches, it can be known that the TNU-SR latch performs well in terms of delay, power consumption, and area, so it is a good choice for radiation-hardened design for space applications. In addition, compared with the latest TNU self-recovery latch (HLTNURL), the TNU-SR latch proposed in this paper reduces the Power-Area-Delay Product (PADP) metric by 111.13%. © 2001-2011 IEEE.
