Internet of Things (IOT) has its importance in the field of data exchange and control, makes great effects when applied in the fitness field. Applying IOT technology in fitness field could introduce an auto judge for fitness competitions by counting the repetitions of any exercise accurately, and exchange data with an accurate preprepared data base. In this paper a novel fitness auto referee (FAR) system has been presented. This system could be emerged as a specialized groundbreaking assistive technology to enhance the accuracy of fitness competitions results validation. The algorithm of the presented system relies on the distinctive physical properties, gender, and age of each player as inputs. The golden ratio or the golden number 1.618 has been employed in this system to locate sensors accurately, also to count the correct repetitions as function of the player tall. This system has the ability to deal with multiplayers simultaneously indoor or outdoor. Last but not least it provides a flexible means to carry out exercises with different groups (males/females - special forces/combat forces - adults/children - athletes/nonathletes. etc.) accurately within a short period of time. © 2024 IEEE.

Human Activity Recognition (HAR) is a research area that involves wearable devices integrating inertial and/or physiological sensors to classify human actions and status across various application domains, such as healthcare, sports, industry, and entertainment. However, executing HAR algorithms on remote devices or the cloud can lead to issues such as latency, bandwidth requirements, and energy consumption. Transitioning towards Edge HAR can be a more effective and versatile solution, overcoming the challenges of traditional HAR techniques. We present a novel HAR model for computation on edge devices: we design a Convolutional Neural Network (CNN) Deep Learning approach and compare its performance with cloud-computing HAR models. The paper is accompanied by a self-collected dataset. The experiments on this dataset demonstrate that the proposed edge computing model achieves promising results (\geq 92 %) in terms of Precision, Recall, and Fl-score. Furthermore, the model exhibits significantly reduced latency, with only 117 ms, and utilizes minimal memory, with a peak of 18.8 Kb RAM and 956 Kb Flash memory. © 2023 IEEE.

Satellite still image plays a crucial role in various domains, such as law enforcement, disaster response, and environmental monitoring. The ability to manually identify objects and facilities within these images is often crucial for these applications. However, given the extensive geographic areas that require coverage and the limited number of analysts available, automation has become a necessity. Traditional object detection and classification algorithms have proven to be insufficiently accurate and reliable for solving this problem. Fortunately, deep learning, a branch of machine learning, offers promising solutions for automating such tasks. One particular approach that has achieved success in image understanding is the use of convolutional neural networks (CNNs). Deep learning has experienced substantial advancements in diverse domains, including computer vision and natural language processing, Despite the progress made in this area, there remains a dearth of comprehensive evaluations concerning datasets and techniques tailored specifically for scene classification using satellite still image. This research paper seeks to bridge this gap by conducting a comprehensive analysis of deep learning, its development over time, and its notable applications within the domain of satellite still image. © 2024 IEEE.

Traffic sign detection and recognition (TSDR) is a pivotal component of contemporary transportation systems, designed to enhance road safety and operational efficiency. In an era where automation is indispensable, TSDR stands out as a critical tool for optimizing driving experiences. This study presents the development of a TSDR model employing advanced deep learning techniques, with a particular emphasis on convolutional neural networks (CNNs). Utilizing the German Traffic Sign Recognition Benchmark (GTSRB) dataset, which comprises annotated images of various traffic signs captured under diverse environmental conditions, we achieved remarkable results. Our CNN models demonstrated a 99% detection rate, underscoring their efficacy in traffic sign recognition tasks. Furthermore, transfer learning models yielded impressive accuracies, with VGG19 achieving 99.64%, EfficientNetB7 reaching 99%, and ASNet attaining 99.72%. Despite these promising results, we identified several limitations, including dataset-specific dep.ndencies and the need for further enhancements in model design and training methodologies. Addressing these challenges is necessary for ensuring the robustness and reliability of intelligent transportation systems, thereby significantly improving road traffic management, safety, and efficiency.

The challenge of credit card fraud presents a significant threat to both consumers and financial institutions alike, leading to substantial economic detriment. In response, this research applies various machine learning strategies to sift through transactional data for the identification of fraudulent activities. Specifically, we employ logistic regression, decision trees, and random forest algorithms to analyze a compiled dataset of genuine and deceptive transactions. This dataset undergoes segmentation into training and testing phases, allowing for a comprehensive assessment of each algorithm's effectiveness. The determination of accuracy scores across these phases serves as a metric for model evaluation. The findings lay down an essential groundwork for ongoing exploration into leveraging machine learning for the mitigation of credit card fraud. The integration of these analytical models promises to bolster the fraud detection capabilities of both financial entities and individual cardholders, significantly reducing the incidence of financial loss. © 2024 IEEE.

This paper aimed to suggest a new Secured Hash Algorithm 3 (SHA-3) with seed value implementation. Seed worth ensuring that there are fewer expectations collisions, despite an attacker selecting the data. Furthermore, attackers who combine seed values with hash functions are prevented from exploiting the properties of a hash function to construct many security attacks, such as denial of service attacks and dictionary attacks. A novel approach to enhanced SHA-3 diffusion was proposed here by XORing the seed value with θ step result after transforming the seed bits into a 5 × 5 × 64 matrix and discarding the rest. © 2023 IEEE.

Robotic arms play an important role in the automation industry. Robotic arms plan processing paths based on the shape of the workpiece. However, the processing path often deviates due to inaccurate placement of the workpiece. To solve the issue of deviations, this paper develops a trajectory compensation system for a robotic arm with offset perception. This system uses the concept of workpiece boundary projection and designs an offset calculation algorithm by comparing the dimensions of the workpiece drawings, correcting errors caused by missing corners of the workpiece. In terms of operation, the system uses photoelectric sensors to quickly scan the workpiece boundary and immediately calculate the displacement and rotational offset of the workpiece. Subsequently, when deviations occur due to different placement positions of the workpiece, the robotic arm's motion path and action must be corrected and compensated to maintain precision. Tests on selected workpieces show that the corrected rotational angle error is less than 0.4 degrees, and the translational error is less than 0.7 millimeters. Since these correction error values are lower than the 1.0 mm error threshold for the robotic arm's trajectory tracking control. The offset-sensing robotic arm trajectory compensation system developed in this study can satisfy the requirements of smart automation production lines and arrive at the manufacturer's application standards. © 2024 The Authors.

Fifth-generation (5G) networks are prone to jamming attacks, which are particularly dangerous in mission-critical applications such as factory automation. In this paper, we present a simple method to detect jamming attacks with machine learning techniques operating on in-phase and quadrature (IQ) modulated signals. In particular, a convolutional autoencoder (CAE) learns the structure of the clean signal to distinguish it from jammed signals in real time. This approach requires only a loose synchronization to the OFDM symbol, while equalization and decoding are not necessary. Despite its simplicity, our technique has shown high detection rates in experiments on a 5G testbed. © 2023 IEEE.
