This paper presents a relative jitter measurement circuit for use in wireline authentication receivers. Design considerations and trade-offs are discussed for a 10 Gbps realization in a 28nm CMOS process. The results show high accuracy jitter measurements over different channel profiles, with the errors less than 1.25% of the bit period. Simulated power consumption indicates minimal overhead to adding the proposed jitter measurement circuit for authentication in a wireline receiver.

A sampled-line reflectometer is presented that uses all-analog computation to produce a voltage proportional to the square of the load reflection coefficient, intended to be integrated into an RF front-end within an array. The novel approach for analog computation, and its dependence on sampler placement along the line is discussed. Experimental measurements of a varying load impedance are demonstrated using a microstrip line with diode samplers, operating at 3 GHz.

The Volterra series is often used to model nonlinear systems in the fields of system identification and adaptive filtering. One means of computing the response of Volterra series-based filters is via input product vector generation. This method is beneficial for applications which utilize the input product vector in addition to the filter’s response. However, the problem of input vector generation as well as the more general problem of Volterra series filtering is computationally complex—as the number of terms within the kernel grows exponentially with the model’s memory and order. This paper proposes a process of Volterra input product vector generation which utilizes the minimal number of multiplication instructions required. This is done by computing permutation and product maps which relate terms in the current iteration’s input product vector to terms within the previous iteration. A MATLAB implementation of the proposed method is applied to the task of Volterra filtering. Its performance is then compared to (a) the MATLAB implementation of a similar, reduced (though not-minimal) multiplication method of input product generation and (b) a "Fast Volterra Filtering" script listed at the MATLAB Central File Exchange. The results show that the proposed method performs comparably to or outperforms both of the other methods for increasing memories and orders of the underlying Volterra kernel.

The objective of this work was the investigation of multiscale Amplitude Modulation - Frequency Modulation (AM-FM) analysis based on Difference of Gaussians (DoG) filterbanks representations in order to predict the risk of stroke by analysing carotid plaques ultrasound images of individuals with asymptomatic carotid stenosis. We computed the instantaneous amplitude, instantaneous phase and the magnitude of instantaneous frequency to extract histogram features on each plaque region. The Support Vectors Machine classifier was implemented to classify asymptomatic versus symptomatic plaques. A dataset of 100 carotid plaque images (50 asymptomatic and 50 symptomatic) were tested, and showed that the AM-FM features based on DoG filterbanks and simple histograms performed better than the traditional AM-FM features. Best results were obtained when an eight scale filterbank with a combination of scales was used reaching the accuracy of 75%.

This paper proposes a novel spike generator for processing in memory (PIM) technology. Most of the electronics today utilize a von Neumann architecture. The von Neumann architecture suffers from the separation of memory and processor. This architecture delays data transfer between memory and processor. To overcome the issues, we utilize the spiking neural network (SNN) that combines memory and processor. SNN can be classified into voltage-based, current-based, and time-based architectures, each with its own pros and cons. Time-based SNN suffers from timing issues. To address the timing sensitivity of time-based neuron SNN, this paper proposes a PWM-based SNN. The PWM-based SNN utilizes pulse width-based logic to overcome timing sensitivity.

The establishment of Peer-to-Peer (P2P) Electric Vehicles (EVs) energy trading markets holds significant importance for optimizing energy exchange among EVs. Despite previous research, challenges remain in enabling distributed pairing of EVs and determining the optimal energy exchange among them. This paper introduces a reinforcement learning mechanism for Charging EVs (CEVs) to autonomously select optimal Discharging EVs (DEVs) and a multilateral bargaining game-theoretic model for determining the optimal procured energy amounts. These innovations enable DEVs to optimize the service provision and profit, thus, contributing to the advancement of P2P EVs energy trading markets. Experimental validation demonstrates the operational characteristics, scalability, and adaptability of the proposed P2P energy trading market model.

Large Language Models (LLMs) are rapidly creating a place for themselves in society. There are numerous reports, both good and bad, of their use in business, academia, government and society. While some organizations are trying to limit, or eliminate, their use, it appears that it is inevitable they will become a common “tool”. In education, there is a fear that students will not acquire critical thinking in the future, but we argue that LLMs will become a tool to assist students with critical thinking, giving guidance, feedback, and assessment. This paper investigates how the current state of LLMs can be integrated into modeling and simulation (M&S) education. Example cases for modeling and simulation development are presented showing how an LLM can assist M&S design and education in anticipation of LLMs becoming a common tool for M&S practitioners. Current limitations are also highlighted, and where possible, short-term solutions are proposed.

The rapidly developing autonomous driving field now needs a more secure transportation system through information between multiple mobility. Deep learning that can judge traffic conditions by convergence of various sensor data and in particular, research on the convolutional neural network using computer vision are being actively conducted. In addition, recognizing many objects at once in a large area through drone images and understanding the movement of the object is used as safe traffic assistance information. In this study, an image classification study is conducted to determine the status of the vehicle on the road through drone flight image data. The goal is to build a new image classification model robust to the proposed image classification network by applying the weighted adversarial learning method. Weight adversarial learning is a method of securing robust performance in image classification of various statuses while disturbing the model by forcibly reflecting the slope value in reverse when updating the network through the reverse gradient layer. In the experiment, model performance is evaluated through the collected drone flight data set.

The automatic classification of medical QA pairs is crucial for improving healthcare efficiency, allocating specialized care, optimizing resource distribution, and facilitating robust data analysis. Bengali, the 7
th
most widely spoken language globally, has a growing volume of health-related queries. However, unlike English, there is no benchmark large-scale medical QA dataset, pre-trained language model, or human baseline score for medical QA in Bengali. This paper introduces a deep learning-based framework called MeQANet that leverages CNN and BiLSTM techniques for classifying medical QA texts in Bengali. It also presents a novel medical QA corpus in Bengali (BnMedQA), consisting of approximately 4500 medical QA pairs across eight domains: Orthopedic, ENT, Gastroenterology and Hepatology, Gynecology, Pediatrics, General Medicine, Dermatology, and Cardiology. Various techniques (including LR, SVM, RF, MNB, AdaBoost (AB), CNN, BiL-STM, and CNN+BiLSTM) are employed to perform the classification tasks. Experimental results indicate that the CNN+BiLSTM approach achieved the highest F1-score of 0.85 among all employed techniques.
