Sign language users tend to be socially restricted due to the general population's lack of knowledge of sign language. Some attempts have been made to develop technologies that improve this aspect by translating sign language. However;these approaches generally use a third-person camera for collecting the information, limiting sign users to environments prepared for this *** this study, we develop a first-person view Japanese fingerspelling recognition system using an Optical See-Through Head Mount Display (OSTHMD). The system estimates the hand posture from the camera mounted on the OSTHMD and applies machine learning to the hand posture data to classify the hand gestures and convert them into speech. 37 Japanese sign language fingerspelling were successfully recognized by using a Microsoft pose extractor. Next, using a support vector machine, 37 out of 53 Japanese sign language fingerspelling were successfully identified with more than 70% identification rate. Finally, the specified labels were converted into speech using the speech output module with Azure *** main purpose of this research is to propose a system that enables sign language users to communicate with verbal people without environmental restrictions. © 2022 IEEE.

In our previous work, we have proposed a method that links character string having a certain semantic meaning on papers in real world to the digital content in cyberspace, and call it "Ultimate Link." Ultimate Link adds additional information to characters by drawing colored circles on top of the characters without changing the shape of the characters. A URL can be generated by connecting additional information of semantically organized character strings from an image taken with a digital device. The conventional Ultimate Link drew markers to normalize the drawn circles (markers for projective transformation), similar to the finder pattern in a QR code. In order to achieve a more realistic application, it is desirable it. We report on an improved Ultimate Link that can handle complex multiple character strings. Specifically, improvements were made to enable extraction of information by identifying character strings with embedded additional information from sheets of paper printed with multiple character strings. As a result of experiments, we confirmed that information could be successfully embedded and extracted for both character strings in the target image.

We proposed a self-localization method using the ToF of sound waves in a system with delays inside a loudspeaker or a microphone. The proposed method uses the time-of-flight (ToF) of sound waves obtained from acoustic ranging sensors and vehicle speed to estimate self-position. The delay due to the loudspeaker or microphone was used as a state variable to estimate the delay time together with the self-position. © 2022 IEEE.

Purpose of Review: As the renewable energy share grows towards CO2 emission reduction by 2050 and decarbonized society, it is crucial to evaluate and analyze the technical and economic feasibility of solar energy. Because concentrating solar power (CSP) and solar photovoltaics (PV)-integrated CSP (CSP-PV) capacity is rapidly increasing in the Asia/Pacific region, this paper provides a review of the development status of commercial-scale CSP and integrated plants and research trends of the related technologies in the Asian and Pacific (APAC) region. Recent Findings: The largest commercial-scale CSP, hybrid CSP-PV, and integrated solar combined cycle (ISCC) plants have been planned and constructed in Australia, China, Saudi Arabia, and the UAE. The research trends of CSP-related technologies in the APAC region are classified into three groups: (1) techno-economic analysis and potential evaluation of CSP and hybrid plants at a commercial scale, (2) development of elemental technology for next-generation CSP and hybrid plants, and (3) importance of thermal energy storage for achieving solar baseload power generation at an affordable LCOE and relatively high efficiency. Summary: This paper reviews the development status of commercial-scale CSP and integrated CSP-PV plants in the APAC region, including the Middle East and Australia. A review of the research status for evaluating technical and economic aspects and a discussion of development trends are also provided. © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

Existing graph neural network (GNN) based recommendation models depend highly on initial node features and graph structures. Most prior studies do not support the use of additional information on user-item interactions and adopt a transductive method, which has limitations for actual web service. To overcome these problems, we propose Context-aware Inductive Graph Matrix Completion (CGMC), which utilizes context vectors that represent user-item interactions and user-item bipartite graph structures in an inductive manner. Our method constructs context vectors from the review, timestamp, and rating and uses them as edge features of the user-item bipartite graph. Relations between homogeneous nodes are also constructed based on common neighbors. Our model combines context vectors and relational information using Context-aware Graph Attention Networks and Edge Fusion Graph Convolutional Networks. We conducted extensive experiments using six real-world datasets, and the results show that the proposed model achieves superior performances over other competing models. Furthermore, we analyzed the inductive characteristics of CGMC through the cross-domain transferability.

Small cracks propagate at the glass surface due to the combined effects of water vapor and applied load. This phenomenon is known as glass fatigue. In this study, four-point bending fatigue tests under static and cyclic loading conditions were conducted for the soda-lime glass plate specimens with the initial crack and indentation pit induced by Vickers diamond indentation. Fatigue cracks were observed by the in-situ crack observation system using optical microscopy in order to obtain the relationship between crack growth rate, da/dt, and maximum stress intensity factor, Kmax, during fatigue tests. The da/dt decreased and then increased with the Kmax value. In addition, photoelasticity was applied to measure the residual stress distribution generated on the surface of the glass. The results showed that the da/dt at the early stage varied with indentation load due to the residual stress, whereas the effect of the indentation load on the da/dt was not observed in the region without residual stress. © 2023 The Society of Materials science, Japan.

Biomechanical Evaluation of the Effect of MIS and COS Surgical Techniques on Patients with Spondylolisthesis using a Musculoskeletal Model

引用

Journal of Biomedical Physics and engineering 2025年第1期15卷 49-66页

作者： Azizi, Sajad Nikkhoo, Mohammad Rostami, Mostafa Cheng, Chih-Hsiu Department of Biomedical Engineering Faculty of Medical Sciences and Technologies Science and Research Branch Islamic Azad University Tehran Iran School of Physical Therapy and Graduate Institute of Rehabilitation Science College of Medicine Chang Gung University Taoyuan Taiwan Bone and Joint Research Center Chang Gung Memorial Hospital Linkou Taiwan Department of Biomedical Engineering Amirkabir University of Technology Tehran Iran

Background: The biomechanical impacts of Conventional Open Surgery (COS) versus Minimally Invasive Surgery (MIS) fusion techniques on adjacent segments and their potential role in developing Adjacent Segment Disease (ASD) remain uncertain for spondylolisthesis. Objective: This study aimed to investigate the impact of MIS and COS fusion surgeries on adjacent spinal segments for spondylolisthesis, through on muscle injury and developing ASD. Material and Methods: This prospective and non-randomized controls study used a validated musculoskeletal model to compare the biomechanical effects of COS and MIS L4 /L5 fusion surgery on patients with spondylolisthesis. The model incorporated kinematic data from 30 patients who underwent each surgery. A sitting task was simulated to model post-operative muscle atrophy, and the analysis focused on changes in biomechanics of adjacent spinal segments. Results: Lumbar flexion was significantly greater (201%) in MIS vs. COS, despite similar pelvic tilt. Consequently, Lumbopelvic Rhythm (LPR) also increased in MIS (133%). Both techniques altered inter-segmental moments. While inter-joint load was higher in COS, only the lower joint’s compressive load was significantly greater (67%). Additionally, MIS required lower overall muscle force with reduced loads and passive moment on spinal joints compared to COS. Conclusion: This study demonstrates that MIS fusion preserves physiological LPR better than COS. MIS maintains normal spinal curvature and maintains lumbar lordosis. While open surgery can lead to abnormal curvature and increased muscle forces to compensate for spinal stability. The study emphasizes the importance of paraspinal muscles in influencing spinal load distribution during MIS compare to COS. © Journal of Biomedical Physics and engineering.
