abstract = {A fractional-order controller is an infinite-memory system. It is described by a continuous time irrational transfer function. Its realization is a delicate problem especially when its parameters are real time tunable. This paper presents a real-time programmable analogue fractional controller implementation. The controller is based on a sum of a novel real-time programmable analogue first-order low-pass filter. The signal within the circuit remains analogue and is not converted into discrete values. Real-time adjustments are made using digital potentiometers and operational amplifiers. The proposed first-order low-pass filter offers several advantages. In particular, the time constant and DC gain are independently adjusted without relying on the ohmic value of digital potentiometers. The time constant and DC gain depend on the resolution of the digital potentiometers. The high resolution of the digital potentiometer enables the circuit to achieve a wide bandwidth and allows for the use of small capacitors at lower frequencies. The proposed real-time programmable analogue fractional controller is experimented to achieve a fractional integrator. The circuit yields good similarity between theoretical simulations and experimental measurements. © 2023 IEEE.},

abstract = {This paper investigates actuator fault estimation for discrete-time switched linear systems subject to unknown but bounded disturbances and measurement noises. By taking the fault as an auxiliary state vector, the proposed method consists of two steps. First, a switched L∞-based descriptor observer attenuating the effect of uncertainties is designed to obtain simultaneous point estimate of the system state and the fault term. Second, interval estimation is achieved by integrating robust point estimation with zonotopic analysis techniques. The observer gains are calculated by solving Linear Matrix Inequality (LMI) derived using a common Lyapunov function. Finally, the effectiveness of the proposed approach is demonstrated through a numerical example. Copyright © 2023 The Authors.

abstract = {In our work, an efficient method to minimize the mutual coupling (MC) from two symmetrical rectangle antennas (Ra) functioning at 26 GHz band is described. This is achieved by adding an arrangement of three split-ring resonator (SRR) cells (placed in the Y-plane) between 2-element MIMO antennas that are positioned in the X-plane. The SRR design is intended to provide bandstop functionality within the antenna bandwidth. As a result, the mutual coupling level is reduced by 23 dB while maintaining the antenna's performance and by packing the MIMO structure with three cells of SRR. In addition, the prototype antenna's simulated isolation varies from -32 to -55 dB on the frequency band of 25.5-26.6 GHz. The reflection coefficient is roughly -40 dB at 26 GHz, with a high gain of 7.5 dB and efficiency higher than 90%. This makes our antenna an effective competitor for MIMO applications at the 26 GHz band enabling the fifth generation (5G) cellular communications. © 2023 IEEE.},

This unique architecture maintains the oversampling frequency across different bands. The reconfigurability of the ADC is achieved by altering the modulator's order. Specifically, in the Bluetooth and Zigbee bands, only the top two stages (2nd order mash 11) are active, while in the Wi-Fi band, all three stages (3rd order mash 111) are engaged.

Nonlinear and uncertain systems are common in many industrial applications, and achieving effective control for them is a major engineering challenge. The Backstepping method, a control technique based on recursion, is first introduced to stabilize nonlinear and uncertain dynamic systems. It allows for the design of successive control laws by progressively moving up the chain of the system's state variables, stabilizing them one by one. This approach offers significant flexibility in handling a variety of nonlinear and uncertain systems. Next, Adaptive Backstepping is presented as an extension of the basic method. This approach takes into account uncertainties and parametric variations in the system, making it particularly well-suited for systems whose characteristics may change over time. Adaptive Backstepping automatically adjusts control laws to maintain system stability and performance, even in the presence of unknown disturbances and uncertainties. © 2023 IEEE.},

A novel approach is introduced to estimate its state in a finite fixed time which can be arbitrarily chosen and is independent of the initial state. For cases where the additive disturbance and measurement noise are known, we provide an exact estimation. Otherwise, a finite-time interval observer is designed. The crucial idea is based on using past values of the input and output of the studied system and a minimal dwell time condition.

The operative PID circuit part is totally analogue. Few digital potentiometers and digital switches are used. This allows to tune the parameters values of the controller and select PI, PD, PID configuration. The analogue circuit part is designed with a new original circuit architecture.

It includes the opinions of healthcare specialists, analyses, prescriptions, and all information concerning the patient. In fact, several actors such as the patient, the doctor, the pharmacist participate in the process of sharing and managing this file. But after the Covid-19 virus pandemic, the use and exchange of paper became dangerous. This need has pushed researchers to find solutions to minimize contact and save medical data in a secure and accessible way. For this purpose, we propose to investigate blockchain distributed ledger technology to manage electronic medical record. Blockchain technology provides just such a solution in the form of a distributed and secure registry that allows patients not only to have visibility over their data, but also to control access to it. In this article, we present a smart electronic medical record based on smart contract. We discuss relevant requirements to guarantee the security of patient data and then propose the system communication process. © 2022 IEEE.},

abstract = {Computer vision has made a significant advance in the medical imaging. Pneumothorax is a severe ailment that can be fatal if the patient does not receive proper care. The main way for diagnosing Pneumothorax is by examining the Chest X-ray by a specialist. The urge of experienced radiologists to anticipate whether someone is suffering from pneumothorax or not by examining chest X-rays is indisputable. Such a facility is not available to everyone. Furthermore, in some circumstances, quick diagnosis is required. In this paper We present a deep learning based image segmentation model capable of predicting Pneumothorax cases by localizing it in chest x-ray exam to help the doctor in making this critical choice. Deep Learning has demonstrated its value in multiple domains, outperforming several state-of-the-arts methods. We seek to overcome this challenge by leveraging deep learning capabilities. We used U-Net architecture with Xception as the encoder and ResNet as a decoder. We obtained encouraging findings, and U-Net works exceptionally well in medical imaging.

This approach proposes uniform and stable cluster formation using Balanced Fuzzy c-mean algorithm with modified centroid. As for Cluster Head selection, three parameters are considered such as Residual energy of the node, Distance from the Base Station and Distance-Ratio.
