The objective of this paper is to develop a robot system that can transmit the video taken by the drone to the computer in real time, use YOLO to recognize the image of pedestrians, and enable the ground robot to plan the path to avoid pedestrians. External sensors, such as laser range finders (LRF) and CCD cameras, are often used on mobile robots. As we all know, these sensors are susceptible to occlusion. Therefore, even if the mobile robot avoids the pedestrian in front of it, it is likely to collide with other pedestrians that cannot be detected due to occlusion. In this study, we used a drone to shoot videos at high altitudes, transferred the videos to a computer, used YOLO on the computer to perform image recognition of pedestrians around the robot, and passed the recognition results to ROS, which enabled it to plan a path to avoid pedestrians around it. As a result, showed that the videos shot at high altitudes could effectively identify pedestrians around the robot after being recognized by YOLO. © 2025 IEEE.

Magnesium-based batteries are potential candidates for next-generation rechargeable batteries due to the divalent nature of magnesium cations and the natural abundance of magnesium resources. In this study, the electrochemical activity of Mg-6mass%Al-3mass%Ca anodes combined with Sn was investigated. Thin ribbons of the anode specimens were prepared by a single-roll rapid solidification method. The results showed that the electrochemical activity increased upon adding 1 mass% Sn, while it decreased for 3 mass% Sn. Based on the results of an X-ray diffraction analysis, the addition of Sn led to the formation of Mg2Sn and Ca2Sn phases, which increased the lattice distortion. Scanning electron microscopy observations indicated that these secondary phases were homogeneously distributed for 1 mass% Sn addition, while they were coarsely distributed for 3 mass% Sn. © 2025 The Japan Institute of Light Metals.

The objective of this paper is to identify the stresses placed on the musculoskeletal system when small dogs walk on floors with low friction coefficients. In many households, and small dogs in particular are often kept indoors. According to veterinary experience, it is known that small dogs kept indoors that walk with their lower limbs slipping cause a great deal of stress on the musculoskeletal system, and that the incidence of joint disease in the lower limbs of such small dogs is high. In this study, we measured the body movements of small dogs walking on slippery floors using a three-dimensional motion capture system and force plate system. Furthermore, by inputting these measurements into the musculoskeletal simulation model we have developed to simulate the musculoskeletal system of dogs, we derived the load on the musculoskeletal system of small dogs on slippery and non-slippery floors. As a result, it was identified that walking on a slippery floor causes a strong load on the lower limb muscles of small dogs. © 2025 IEEE.

Assessing disruptive potential of retail central bank digital currency and influence of design considerations: An open innovation approach in Thailand

引用

Journal of Open Innovation: technology, Market, and Complexity 2025年第1期11卷

作者： Wathahong, Thanwa Ratanabanchuen, Roongkiat Israsena Na Ayudhya, Praima Tientanopajai, Kitt Technology Management and Innopreneurship Program Graduate School Chulalongkorn University Phayathai Road Bangkok 10330 Thailand Department of Banking and Finance Chulalongkorn Business School Chulalongkorn University Phayathai Road Bangkok 10330 Thailand Department of Industrial Design Faculty of Architecture Chulalongkorn University Phayathai Road Bangkok 10330 Thailand Department of Computer Engineering Faculty of Engineering Khon Kaen University Mittraphap Road Khon Kaen 40002 Thailand

Monetary authorities globally have studied central bank digital currency (CBDC) for wholesale and retail applications since the 1990s. Besides countering private cryptocurrencies' influence, central banks have also explored other benefits of CBDC, such as improving their financial oversight, enhancing digital payment systems, and reducing transaction fees and friction. For several years, the Bank of Thailand has also invested in research and development of CBDC, including retail use cases. However, an optimized design for an official launch of a retail CBDC in Thailand has yet to be determined, resembling fragmented progress observed among other central banks. This research has leveraged disruptive innovation theory to provide a fresh perspective on retail CBDC as potentially disruptive financial innovations. Additionally, it has proposed an open innovation-based methodology to determine industry preferences concerning twelve design considerations for retail CBDC and their impact on nine indicators of disruptive innovation. Data has been collected and analyzed from 98 respondents outside the Bank of Thailand, all possessing relevant expertise or experience in electronic payments. Crosstab and logistic regression analyses have indicated that retail CBDC in Thailand could embark on a disruptive innovation trajectory by adhering to defined design choices. Significantly, entering a new detached market has been identified as the most promising entry point, accompanied by explicit recommendations on nine out of twelve design considerations. © 2025 The Authors

Selection of Suitable Maximum-heart-rate Formulas for Use with Karvonen Formula to Calculate Exercise Intensity

引用

International Journal of Automation and computing 2015年第1期12卷 62-69页

作者： Jinhua She Hitoshi Nakamura Koji Makino Yasuhiro Ohyama Hiroshi Hashimoto Graduate School of Bionics Computer and Media Sciences Tokyo University of Technology 1404-1 KatakuraHachioji Tokyo 192-0982 Japan Interdisciplinary Graduate School of Medical and Engineering University of Yamanashi4-3-11 Takeda Kofu 400-8511 Japan Master Program of Innovation for Design and Engineering Advanced Institute of Industrial Technology 1-10-40 HigashiooiShinagawa-ku Tokyo 140-0011 Japan

The Karvonen formula, which is widely used to estimate exercise intensity, contains maximum heart rate, H Rmax, as a variable. This study employed pedaling experiments to assess which of the proposed formulas for calculating H Rmaxwas the most suitable for use with the Karvonen formula. First, two kinds of experiments involving an ergometer were performed: an all-in-one-day experiment that tested eight pedaling loads in one day, and a one-load-per-day experiment that tested one load per day for eight days.A comparison of the data on 7 subjects showed that the all-in-one-day type of experiment was better for assessing H Rmaxformulas,at least for the load levels tested in our experiments. A statistical analysis of the experimental data on 47 subjects showed two of the H Rmaxformulas to be suitable for use in the Karvonen formula to estimate exercise intensity for males in their 20 s. In addition, the physical characteristics of a person having the greatest impact on exercise intensity were determined.

In recent years, the demand for service robots is increasing all over the world. Service robots have the purpose to assist living, such as medical treatment, transportation and security, and tend to have the function which move automatically in an environment. When operating such an autonomous mobile robot in a real world, the obstacle avoidance is the necessary technique to use a robot safely. A robot has to avoid static obstacles such as garden plants or signboards, and dynamic one such as pedestrians, and especially the robot has to act with caution to pedestrians. The purpose of this paper is analysis of human walking characteristics from the movement of a pedestrian, and from the experimental result, it turned out that the future movement of a pedestrian will be able to predict by movements of a few pedestrians. © 2014 IEEE.

Preservations and utilization of culture asset is one out of most discussed issues worldwide, whether it is tangible or intangible cultural asset. The emphasis on inherited human-oriented memories, through influential and important of story-telling is vital. If the cultural asset was being redeveloped and managed inappropriately, it will disengage the main concept of preserving cultural asset, affecting local culture and its historical heritage, which may lead to poor maintenance, or in contrast, an excessive commercialization on cultural assets. Kinmen, offshore island of Taiwan, contains the most cultural asset in Taiwan. It has preserved traditional Minnan tribe culture in their lives and buildings. They work hard to protect, repair, and introduce their culture, letting others experience their ancestor’s smart living and feel the dynamic of local people in passing down their cultural heritage. Alongside its rich cultural heritage, Kinmen has turned from being a "sad heritage" (confrontation, war, and tragedy) into an "inspiring heritage" (reconcile, peace and reborn) and serves as a guidance and an inspiration for us in searching the value of peace. Based on Kinmen’s importance on Minnan cultural heritage and the possible impacts of the gambling industry on cultural assets, this research will be using Kinmen as a study subject and organize its cultural assets by utilizing AHP analysis values with discussion of the gambling industry’s impact;then taking further to drive the diversity of impacts by using FDM analysis. © 2018, Springer Nature Singapore Pte Ltd.
