The focal point of this work is to automatically detect metaphor instances in short texts. It is the study of extricating the most optimal features for the task by using a deep learning architecture and carefully hand-crafted contextual features. The first feature set is created using a Convolutional Neural Network (CNN) architecture. Then, three other feature sets are manually hand-crafted using contextual justifications. Next, all of the feature sets are combined. Finally, the combined feature sets undergo the classification process using Support Vector Machine, Logistic Regression, Decision Tree, K-Nearest Neighbour and Discriminatory Analysis. These well-known ma-chine learning classification algorithms are used at the same time for the purpose of comparison. The best algorithm for this task is found to be Support Vector Machine (SVM). The outcome of all the experiments using SVM are good in all the metrics used, with F1-measure of 0.83. Finally, comparison to existing works and performance of each feature sets are given. It is also found that a few sets performed well when they are used independently. However, even the sets that are not useful separately is proven to be very useful after the combination process. © 2022 IEEE.

DC Microgrids are rapidly developing, driven by the increasing integration of renewable sources and dynamic loads. Their growing adoption in critical applications raises the need for operational safety and reliability, particularly under fault conditions. This paper presents a sensor fault-tolerant control (FTC) for DC-DC power converters in DC Microgrids designed to maintain resilient and reliable operation. The proposed FTC leverages a single Switching Unknown Input Observer (SW-UIO) at the bottom control level to estimate arbitrary sensor faults with a high accuracy (0.3% fault estimation error), allowing a real-time identification and precise control reconfiguration to accommodate sensor faults with minimal computational burden. The approach is validated under diverse conditions, including time-varying loads, complete sensor failure, noise abnormality, and simultaneous faults/failure, achieving a consistent fault accommodation of 1 μs from fault occurrence to compensation. Real-time simulation has been performed in the OPAL-RT environment to assess the efficacy and superiority of the proposed sensor fault tolerant strategy in comparison to reference FTC strategies. © 2013 IEEE.

This paper presents the study on how to dimension the receiver's coil in resonant wireless power transfer system. One of the key features of the wireless power transfer system is the efficiency of the power transfer. To achieve high efficiency, two main coil parameters must be optimized: number of coil windings and coil surface area. This paper presents a mathematical model for coil parameter calculation. Comparison with measurement results shows that the accuracy of the calculated values is higher than 90%. © 2022 IEEE.

Recognition of human activities using wearable sensors is essential for applications related to health and well-being. However, the complex data captured by inertial sensors poses challenges in accurately identifying actions. This research introduces MotionNeXt, a residual deep neural network incorporating aggregated transformation. MotionNeXt utilizes residual and multi-kernel blocks to extract spatial and temporal characteristics from raw IMU data. Subsequently, it employs global average pooling, a fully connected layer, and softmax for classification purposes. An attention layer enables the model to focus on specific segments of the input sequence while categorizing each time step. MotionNeXt is evaluated using a publicly available dataset of activities collected from wearable inertial measurement devices. It achieves state-of-the-art accuracy, boasting an F1-score of 99.37%, surpassing previous deep learning methods by 2- 5%. By integrating accelerometer, gyroscope, and magnetometer modalities, MotionNeXt mitigates the limitations of individual inputs, significantly improving accuracy across various models. © 2024 IEEE.

Speech Emotion Recognition (SER) has become an indispensable part of human-computer interaction. In order to obtain a higher recognition rate, in this paper, a joint feature based on Philips fingerprint and spectral entropy is used, and it is combined with some underlying features to perform speech emotion recognition on the four emotions of angry, neutral, happy, and sad. Firstly, the Mel Frequency Cepstral Coefficients (MFCC), Linear Prediction Coefficient (LPC), logarithmic amplitude-frequency characteristics, Philips fingerprints and spectral entropy are extracted for speech dataset. Secondly, Principal Component Analysis (PCA) is used to reduce the dimension of the extracted feature. Thirdly, SVM is used to train and classify the features after dimension reduction. The experimental results show that by comparing the recognition results with other feature combinations, the method proposed in this paper has good recognition results. © 2022 ACM.

The advancement of interoperable digital technology has had remarkable impacts on society especially in the healthcare area. Ischemic heart disease is a major cause of disability and premature death in many parts of the world that can still be mitigated through lifestyle changes. While the existing mHealth solutions that encourage users to maintain healthy lifestyle habits do exist, they lack the reliable advice of healthcare professionals to monitor patient's lifestyle habits remotely. The process of manually collecting patient data for analysis and clinical testing can also be time-consuming for healthcare professionals. Therefore, this study proposed a webbased information system to monitor lifestyle habits and habit-change of people prone to heart disease. The system collects lifestyle habit data from a smartwatch and smartphone. Then, the system utilizes machine learning techniques to classify the patient's lifestyle habit data such as diet, exercise, and sleep. Furthermore, the system is used to upload echocardiograms during the echocardiography test in the hospitals and receive the echocardiography results. The data analytical results are visualized on an intelligent dashboard that can be viewed by doctors using the web application. The system is expected to support doctors in decision-making for digital care pathways in order to provide timely intervention for lifestyle modifications. © 2023 CEUR-WS. All rights reserved.
