IEEE International Workshop on Robot and Human Communication (ROMAN)

作者： Haruto Mukuno Daigo Misaki Graduate School of Engineering Mechanical Engineering Program Kogakuin University Tokyo Japan Faculty of Engineering Department of Mechanical Systems Engineering Kogakuin University Tokyo Japan

The COVID-19 pandemic has popularized telework using video chat tools. Although video chat tools allow people to communicate each other in remote locations, psychological distance is longer than face-to-face communication, which may lead to a lack of intimacy. Previous studies have shown that interfaces combining video chat, VR, and robots with handshakes can improve the sense of closeness. However, few studies have focused on the sense of closeness in interfaces combining VR and robots. In this study, we proposed a multimodal interface combining VR and a robotic arm and verified whether shaking hands with a remote partner in VR could shorten the psychological distance compared to video chat. The results showed that the psychological distance was predominantly shorter in VR communication than in video chat communication; however, a handshake using robotic arm did not shorten the psychological distance compared to a handshake without a robotic arm. These results indicate that spatial distance is shorter in VR than in video chat and that robotic arms must be made more human-like.

Environmental Science and Pollution Research 2024年第22期31卷 32875-32900页

作者： Ghanem, Ma’in Abed Alhakim Naser Zaifoglu, Hasan Sustainable Environment and Energy Systems Middle East Technical University Northern Cyprus Campus Orta Dogu Teknik Universitesi - Kuzey Kibris Kampusu Guzelyurt Via Mersin 10 Kalkanli99738 Turkey Civil Engineering Program Middle East Technical University Northern Cyprus Campus Orta Dogu Teknik Universitesi - Kuzey Kibris Kampusu Guzelyurt Via Mersin 10 Kalkanli99738 Turkey

Over the past few decades, flood disasters have emerged as the predominant natural hazard in Cyprus, primarily driven by the escalating influence of climate change in the Mediterranean region. In view of this, the objective of this study is to develop a geospatial flood risk map for the island of Cyprus by considering 14 flood hazard factors and five flood vulnerability factors, utilizing geographic information systems (GIS) and remotely sensed datasets. A comparative assessment was conducted for hazard mapping, employing statistical methods of frequency ratio (FR) and FR Shannon’s entropy (FR-SE), and multi-criteria decision analysis method of fuzzy analytic hierarchy process (F-AHP). The main findings indicated that the FR method exhibited the highest predictive capability, establishing it as the most suitable approach for flood hazard mapping. Additionally, vulnerability factors were aggregated using F-AHP to generate the vulnerability map. The resulting flood risk map, which is the product of flood hazard and flood vulnerability, revealed that 9% of the island was located within highly risky regions, while 13.2% was classified as moderate risk zones. Spatial analysis of these high-risk areas indicated their concentration in the primary city districts of the island. Therefore, to mitigate future risks within these cities, an analysis of potential expansion zones was conducted, identifying the best-suited zone exhibiting the lowest risk. The generated flood risk map can serve as a valuable resource for decision-makers on the island, facilitating the integration of flood risk analysis into urban management plans. © The Author(s) 2024.

Organizations face an urgent need to become faster, more efficient, and more successful in their commercial operations, given the current state of technological evolution and the arrival of Industry 4.0. Many businesses have adopted the idea of enterprise resource planning (ERP) systems to achieve this goal. The ERP system is expected to increase worker productivity, improve business performance to maximize profitability and profits, and provide accurate and up-to-date data and information to management and stakeholders. This research aims to find new variables related to integration problems in the use of ERP systems. Using the SPSS statistical program, the data collected will be examined using quantitative exploratory factor analysis (EFA). Data processing then includes collecting demographic information from respondents, reliability testing, conducting the Kaiser-Meyer-Olkin (KMO) test, testing using an anti-image matrix, and deriving new factors using a rotation component matrix. This research seeks to identify new elements underlying ongoing integration problems in ERP system implementation. The research results show several reasons for underlying integration problems and offer in-depth information to management that can be used to analyze and evaluate the ERP system in their company appropriately in the future so that the company's performance becomes superior to the competition.

Jogging has become a popular urban outdoor recreational activity because it is inexpensive and easy. Although there are positive responses to leisure-route planning from many regions, the routes with features preferred by joggers are not commonly considered in urban planning. This article explores and evaluates methods for determining optimal urban jogging routes while considering joggers’ preferences. This study combines information about road width, green space, riverbank scenery, and various points of interest with jogging heat map data and uses a decision tree analysis to study joggers’ preferences. Next, routes with high potential considering three different patterns of points of interest and road width are selected using the vehicle routing problem analysis in ArcGIS. This method for preference-based route selection can be used to identify which links in urban road networks are attractive to runners and provide policymakers with useful information for designing built environments. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

Proximity results in convex mixed-integer programming

We study proximity (resp. integrality gap), that is, the distance (resp. difference) between the optimal solutions (resp. optimal values) of convex integer programs (IP) and the optimal solutions (resp. optimal values) of their continuous relaxations. We show that these values can be upper bounded in terms of the recession cone of the feasible region of the continuous relaxation when the recession cone is fulldimensional. If the recession cone is not full-dimensional we give sufficient conditions to obtain a finite integrality gap. We then specialize our analysis to second-order conic IPs. In the case the feasible region is defined by a single Lorentz cone constraint, we give upper bounds on proximity and integrality gap in terms of the data of the problem (the objective function vector, the matrix defining the conic constraint, the right-hand side, and the covering radius of a related lattice). We also give conditions for these bounds to be independent of the right-hand side, akin to the linear IP case. Finally, in the case the feasible region is defined by multiple Lorentz cone constraints, we show that, in general, we cannot give bounds that are independent of the corresponding right-hand side. Although our results are presented for the integer lattice Zn, the bounds can be easily adapted to work for any general lattice, including the usual mixed-integer lattice Zn1 × Rn2 , by considering the appropriate covering radius when needed.

作者： Mateus Abreu de Andrade Rodolfo César Costa Flesch Graduate Program in Automation and Systems Engineering Universidade Federal de Santa Catarina Florianópolis Brazil

A factor that must be taken into account in the modern design of power electronics converters is the reliability of dc-link capacitors, but traditional condition monitoring methods require extra hardware that increase the overall cost. This work proposes and experimentally evaluates a condition monitoring method for electrolytic dc-link capacitors in three-phase front-end diode rectifier motor drives which does not require hardware modifications. The presented method uses an artificial neural network (ANN) to predict the capacitance value of the dc-link capacitor bank. Based on time-domain parameters, the ANN is trained and evaluated using an error analysis to determine the effectiveness of the proposed method with a printed circuit board capacitor jig and aged samples. The proposed method is evaluated in several operating conditions and the results show that the prediction errors are less than 2.4% and that the method is able to monitor the degradation level of the dc-link capacitor bank.

作者： Sawada Nonoka Akira Uehara Hiroaki Kawamoto Yoshiyuki Sankai Master's Program in Intelligent and Mechanical Interaction Systems University of Tsukuba Ibaraki Japan Institute of Systems and Information Engineering Center for Cybernics Research University of Tsukuba Tsukuba Ibaraki Japan

This study centers its attention on communication among ALS patients with severe symptoms, which is essential to daily life and the part that remains a difficulty. Also, communication is important to promote social participation and ability of independence. To promote social participation and improve the ability of independence without the restrictions for patients, the purpose of this study is to develop a wearable interface that enables communication based on the patient's voluntary intent, without temporal, spatial, or physical restrictions, and to confirm the feasibility of intention transmission using a new text entry algorithm. The developed interface utilized a see-through type head-mounted display (HMD) with a gaze estimation sensor to enable patients themselves to transition between cyberspace and physical space and to communicate by the system without restrictions of posture or usage environment during daily life activities. The letter selection is triggered by a change in the direction of the gaze trajectory. This method of letter selection reduces the burden on the user by avoiding the effects of dwell time and other factors associated with gazing input. The key layout for text input UI considers the characteristics of human eye movements, to minimize key selection errors and allows for quick viewpoint movement. To confirm the feasibility of the basic performance, we conducted the experiment with three able-bodied participants using the developed system and a conventional system as a comparison system, respectively. As a result, the developed system was able to input sentences in the same amount of time as the conventional system. The results show that the developed system has the basic performance of a communication interface with a new character input method based on eye movement functions. Therefore, we confirmed the feasibility of transmitting intention using a new text entry algorithm to enable communication without the restrictions.

This paper presents a novel approach for noninvasive glucose monitoring using a Compact Complementary Split Ring Resonator (CCSRR) based sensor. The sensor design is initially simulated using High-Frequency Structure Simulator (HFSS) software, and then experimental validation is done. We carried out simulations with and without a finger phantom model to closely resemble conditions in real situations. The sensor exhibits high sensitivity and accuracy in detecting glucose concentrations within blood samples. Vector Network Analyzer was used along with the sensor to validate the simulation results. The results demonstrate close agreement between simulation and experimental data, affirming the effectiveness of the proposed sensor design for non-invasive glucose monitoring.
