Optimization and evaluation of a mobile IMU-based ballistocardiography system

Current Directions in Biomedical engineering 2023年第1期9卷 678-681页

In recent decades ballistocardiography (BCG) has regained popularity as a way to measure the mechanical activ- ity of the heart. In this paper we present and evaluate a new iteration of our mobile BCG measurement system. The pro- posed system uses an inertial measurement unit (IMU) placed on the carotid artery to derive the BCG. We conducted a mea- surement series to evaluate the system and to do an initial in- vestigation into whether more complex heart parameters can be derived from BCG data. The evaluation shows that heart rate (HR) and heart rate variability (HRV) calculated using BCG data, agrees well with the reference measurement and amplitudes calculated are mostly comparable in range to other papers. In conclusion, the system can reliably derive features from BCG data that can be used in further research. © 2023 the author(s), published by Walter de Gruyter Berlin/Boston.

WSN security is a current area of research for many scientists. One of the best security tools for defending the network from malicious assaults or the unauthenticated access is IDS. In this article, we suggest an optimized hybrid classification model-based IDS with certain steps to follow. In preprocessing, the issue of class imbalance data is solved using SMOTE. A collection of features, including raw features, statistical features, and entropy features are extracted in the feature extraction step. Optimal feature selection is done based on the extracted feature set via proposed SI-BWO (Self Improved Beluga Whale Optimization) algorithm. Attack detection is the next stage, in which hybrid classification will be takes place by combining the CNN and DBN model. The same SI-BWO algorithm is used to perform the hybrid model's optimum training. Once an attack has been detected, the attack mitigation procedure is then carried out. © 2024 IEEE.

Wearable devices for arrhythmia diagnosis are battery-powered and require improved power efficiency. In our previous study, we applied approximate computing, which is effective for power reduction, to QRS identification algorithm and achieved significant power reduction. However, the impact of this approximation on arrhythmia detection and classification was not fully investigated. In this study, we investigate how the approximation - - specifically, the use of two approximate multipliers and eight approximate squarers applied to the Pan-Tompkins algorithm - - affects RR interval-based arrhythmia detection and classification. We use 48 samples from the MIT-BIH Arrhythmia Database to evaluate the accuracy of arrhythmia detection and classification. It was found that the approximate multiplier mul16s_GQU is the best choice, achieving nearly 100% accuracy and less than 1 % false negatives in abnormal/normal classification. Additionally, the most power-efficient approximate squarer, E10C1, achieves relatively high accuracy with less than 5 % false negatives. © 2024 IEEE.

The Internet of Things (IoT) stands as a revolutionary leap in digital connectivity, envisioning a future network connecting billions of devices, seamlessly. Amidst the myriad benefits, there arises an intricate web of challenges, prominently centered around potential threats and data security implications. Recent cryptography techniques, such as DNA-based cryptography, 3D chaos-based cryptography, and optical cryptography, face challenges including large encryption times, high energy consumption, and suboptimal rather than optimal performance. Particularly, the burden of long encryption cycles strains the energy resources of typical low-power and compact IoT devices. These challenges render the devices vulnerable to unauthorized breaches, despite large storage capacities. The hallmark of the IoT ecosystem, characterized by its low-power compact devices, is the burgeoning volume of data they generate. This escalating data influx, while necessitating expansive storage, remains vulnerable to unauthorized access and breaches. Historically, encryption algorithms, with their multifaceted architectures, have been the bulwark against such intrusions. However, their inherently-complex nature, entailing multiple encryption cycles, strains the limited energy reserves of typical IoT devices. In response to this intricate dilemma, we present a hybrid lightweight encryption strategy. Our algorithm innovatively leverages both one-dimensional (1D) and two-dimensional (2D) chaotic key generators. Furthermore, it amalgamates a classical encryption philosophy, harmonizing the strengths of Feistel and substitution-permutation networks. The centerpiece of our strategy is achieving effective encryption in merely three rounds, tailored expressly for compressed Three-Dimensional Video (3DV) frames, ensuring their unwavering integrity. Our workflow commences with the H.264/MVC compression algorithm, setting the stage for the subsequent encryption phase. Through rigorous MATLAB simulations,

The Indonesian republic police have provided services to the community by facilitating reporting via WhatsApp. However, messages sent through WhatsApp require manual identification to determine the type of offense reported by the public. Therefore, this research aims to assist in this process by applying deep learning approaches, specifically Convolutional Neural Network (CNN) and Bidirectional Long Short-Term Memory (BiLSTM). Despite the high accuracy of CNN and BiLSTM in some classifications, their performance varies depending on the dataset. This study enhances both the architecture and data preprocessing, including class balancing using SMOTE. To prevent overfitting, early stopping is applied during training. The optimization process in this study utilizes the Adam optimizer, known for its efficiency in handling large-scale data and its ability to adapt the learning rate. The experimental results indicate that while early stopping effectively mitigates overfitting, the resulting accuracy of 68% is not optimal. Without early stopping, the accuracy improves to 91 % for CNN and 98% for BiLSTM. These findings confirm that stopping models at the right moment and the choice of data augmentation and split techniques significantly impact the overall accuracy, making them crucial aspects of this research. © 2024 IEEE.

In the context of online news outlets like Twitter, our work gives a summary of the situation as of rumor identification utilizing visual content. The majority of studies in the literature use visual content to illustrate several solutions to the issue. As opposed to combining them, we suggested an approach for Twitter rumours. The majority of our research work focuses on the use of supervised techniques, particularly deep learning models by utilising the deduced feature sets from the Twitter MediaEval dataset, which included 3000 images in total, a VGG-19 deep neural network was trained and evaluated. The VGG-19 achieves a highest sensitivity and an accuracy of using features taken from images during training and testing, which struggle to function in situations other than those in which they were trained. The simulation findings show that compared to other state-of-the-art architecture, the suggested design is more accurate and sensitive. © 2024 IEEE.
