Citrus Limon L. (Lemon) is a type of fruit that is currently widely consumed, because it contains abundant vitamin C, fiber, and antioxidants. This fruit have high potential in the agribusiness sector and is widely cultivated by traditional farmers. However, during harvest time, traditional farmers generally still use manual methods using the human eye in distinguishing the maturity level of lemons which is less efficient because it has a low accuracy. Digital image processing is one solution to this problem. In the research on the classification of lemon maturity levels using digital image processing with the feature extraction method of the Mean RGB, HSV, and LBP methods and the K-Nearest Neighbor classification algorithm in this study, a total of 120 lemon images were used which were divided into 80 training image data and 40 image data. testing. The results of model performance measurements in the form of the highest accuracy level in the Mean RGB method of 100%, the highest accuracy in the HSV method of 98%, and the highest accuracy in the LBP method of 82.5%. © 2023 IEEE.

As global road infrastructure expands rapidly, especially in developing countries, maintaining the quality and safety of these roads becomes critical. However, many routes lack detours, and the swift deterioration of these busy roads raises serious concerns. Therefore, there is an urgent need for a cost-effective, quick inspection method. This study proposes a solution through drive-by monitoring. We utilized commercial buses with vibration sensors and Global Positioning System (GPS) devices. The GPS receivers, acting as accurate clocks, could record the bus’s location while providing space- and time-synchronization for the simultaneously measured vibration data. For this study, we installed an acceleration sensor under each bus seat. We can convert the recorded vehicle vibration data into road unevenness information, assuming specific vehicle parameters. To minimize errors, we updated the assumed parameters to align more closely with the average road unevenness versus the estimated unevenness from each bus. We employed a Genetic Algorithm, a search heuristic that mimics the process of natural evolution, to update these parameters. Through this methodology, we could estimate vehicle parameters and road unevenness, paving the way for an efficient, low-cost road inspection method. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

This paper proposes a measurement technique for an integrated complex filter. The proposed method is based on two measurement methods with integrated circuitry for calibration. It is accomplished by applying square waves to an FUT (Filter Under Test) instead of sinusoidal waves or by superposing transfer characteristics obtained by applying a single sinusoidal wave to an FUT. In both of the above methods, the output signal connected to the external measurement equipment via a 50 Ω coaxial cable and so on. In this case, the output signal of the FUT should be amplified by internal or external amplifiers, which degrades the response. However, it is cancelled out by the proposed calibration circuitry with some analog switches. In addition to the above, for the RC polyphase filter, the source resistance and the load capacitance degrade the measurement results and their effect is discussed. The validity of the proposal is confirmed through computer simulation for a third-order RCPF whose passband is 8–40 MHz fabricated by Phenitec 0.6 µm CMOS process. It is shown that the measurement error is −1.10 dB for the square-wave method and −1.00 dB and −0.43 degrees for the superposition method at 40 MHz. © 2025 The Institute of Electrical Engineers of Japan.

This study provides an initial exploration and further understanding of the factors that are parameters in evaluating the success of Enterprise Architecture (EA) implementation. An evaluation process is needed to ensure that the EA project implementation provides effectiveness, efficiency, and feasibility of the EA information system as well as assessing previous project experience to avoid future EA project risks. The research aims to present a Systematic Literature Review based on the stages of identification, screening, eligibility, and inclusion so that 14 main articles are selected for review with strong actual relevance. The study results provide insights and references that can be used to further explore key factors in evaluating the success of EA implementation in the future. It was found that there were ten factors that most influenced the evaluation of the success of EA implementation and it was concluded that two potential factors were the most influential and required further exploration in evaluating the success of EA implementation which could be applied in various sectors/dimensions. This study contributes as an initial reference for overcoming problems in investigating and exploring the factors that influence the success of EA implementation as an effort to assess the success of achieving future organizational goals. © 2024 IEEE.

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. © 2024 IEEE.

Many Internet protocol (IP) lookup algorithms have been formulated to improve network performance. This study reviewed and experimentally evaluated technologies for trie-based methods that reduce memory access, memory consumption and IP lookup time. Experiments involving binary tries (for simplicity) were conducted on four real-world data sets, two of which were on IPv4 router tables (855,997 and 876,489 active prefixes) and two of which were on IPv6 router tables (155,310 and 157,579 active prefixes). Technologies designed to reduce time taken (at the expense of memory consumption) worked well for IPv4, and those designed to reduce memory consumption worked well for IPv6. Various combinations of these technologies were applied together in the experiments. © 2022 Elsevier Inc.

Bridge has a diversity. Various environments and backgrounds create a uniqueness of the bridge, making inspection and evaluation difficult. In Japan, the number of bridges 50 years after construction has been increasing, on the other hands, regular inspections have become mandatory, however the efficiency was not high because of visual inspection. This study focuses on vibration of vehicle going on the bridge. Since it is difficult to estimate accurate bridge vibration from vehicle vibration because the vehicle-bridge interaction is complex dynamics problem, the technology is applied as a screening technique. Screening technique can optimize the resource (e.g.: human and sensor) for inspection, evaluation and repair by carrying out of the triage of bridges which have to be inspected in detail. The vehicle sensor is designed based on a common concept considering in future installation on bridges. Due to detect the effects of structural changes, it is necessary that the quantization bit rate of the Analog-Digital converter (ADC) is high. Previous study uses 12 t16 bits commonly, thus this study developed several acceleration sensor devices which mount an ADC of 17 and 23 bits and experimented on actual bridge. Sensors were installed on both the vehicle and the bridge, and the vibrations of both sensors were compared and evaluated. The criterion for identification uses Spatial Singular Mode Angle (SSMA) which assumes bridge vibration from interpolated vehicle ones by singular values decomposition. SSMA has been proved as damage detection criterion for bridge through previous study. Although it is difficult for vehicle sensors to completely reproduce bridge vibrations, it was suggested that statistical analysis of SSMA etc.. may capture structural change of actual bridge.

This research aims to build a mathematical model to formulate the problems of implementing knowledge management systems in companies that often face obstacles in achieving the desired objectives and goals. With increasing competition in the business sector, organizations or organizations realize the importance of utilizing the knowledge assets that reside in each individual and organization. If this knowledge can be managed optimally, it can become a competitive advantage for the company due to the emergence of innovative ideas by the concepts of knowledge management theory. By implementing optimal knowledge management (KM), companies can design innovative solutions to improve business operations and increase overall revenue. The factor analysis method will be used to find the determining factors for the success of the implementation of knowledge management systems (KMS) and the regression analysis method will also be used to form a mathematical model of several new factors which are formed as independent variables with the current level of community understanding of KMS as the dependent variable. The research results provide insight into strategies to improve success factors to successfully facilitate KMS implementation. This study contributes to existing knowledge management by providing insight into dynamics that go beyond the technical aspects of KMS, ultimately developing strategies for more effective and efficient utilization of knowledge and organizational growth and supporting competitive advantage for companies. © 2024 IEEE.
