abstract = {Multiple Sclerosis (MS) lesions is a chronic autoimmune inflammatory disease that affects the nerves in the spinal cord and the brain. Magnetic Resonance Imaging (MRI) is a successful, highly sensitive MS lesion diagnostic technique. It is used to monitor the activity and progression of this disease. Monitoring the progression of multiple sclerosis (MS) is crucial for timely intervention and treatment adjustments, as it can help improve patients' quality of life and contribute to ongoing research efforts to better understand the disease. This paper uses two techniques to monitor MS lesions progression: the Decimal Descriptor Pattern (DDP) and the Local Binary Pattern (LBP). These operators are used to extract the most important features and to characterize the properties of the structures in the brain. 3D MRI brain are described using a collection of orthogonal planes. We have developed an extension to the DDP descriptor to improve the performance in MS evolution. Our results are proof that our approach is effective and fast. © 2023 IEEE.},

abstract = {For future mobile communications networks, a key challenge is to offer and retain a number of parameters, like high data rates, while preserving a greater degree of service quality (QoS). Main performance indexes lower latency and power consumption. It's widely known that this is the most reliable choice for the post-fifth physical layer. Mobile networks adopt a famous modulation model named OTFS (Orthogonal Time-Frequency Space). So, the paper concerns how better an equalization procedure will be based on both ZF (zero forcing) and MMSE (minimum mean square error equalization) with respect to offered complexity. The effectiveness of these various strategies will be investigated in this study with reference to the obtained simulation results. © 2023 IEEE.},

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 = {In this research, we present an approach to improve thyroid diagnosis and provide experts in medical fields by leveraging artificial intelligence (AI) technology. Our research aims to speed up the diagnostic process, particularly in emergency situations where specialized medical personnel are not always available. Our technology includes a user-friendly interface that enables healthcare professionals to efficiently submit ultrasound scans of their patients' thyroids. The images are then analyzed using integrated AI algorithms based on the YOLOv5 object detection model. In real-time, these algorithms efficiently and rapidly identify and localize thyroid areas. With an overall precision rate of 0.879 and a recall rate of 0.862, the results show a high degree of precision and recall. The average precision (mAP50) is 0.892, confirming the accuracy of localization. The system offers invaluable support to healthcare professionals with comprehensive reports and annotations, facilitating informed decision-making and patient care.

Observer gains are derived from the solution of Linear Matrix Inequalities (LMIs), based on the use of a common Lyapunov function, to ensure cooperativity and stability. An L∞ technique is then introduced to compensate the measurement noise and disturbances' effects and to enhance the precision of interval estimation. Finally, numerical simulations are given, evaluating the proposed methodology and demonstrating its effectiveness. © 2023 IEEE.},

Each vehicle wishing to be part of this platoon must send a configuration and registration message and must provide the necessary information to be part of the platoon. This new feature can reduce traffic congestion and save energy. This article, paves the way for the emergence of a new type of driving system that we will call "EX-platoon"extensible platoon abbreviation. Thus, through this document, we will develop a model based on a Petri network describing the flow of messages exchanged between the different parts of this system necessary to allow the cooperative driving system to be extensible.

abstract = {In this paper, zonotopic fault detection methodology is proposed for a class of discrete-Time Linear Parameter Varying (LPV) systems with sensor faults. The disturbances and measurement noise are assumed to be unknown but bounded by zonotope. First, a fault detection observer is designed based on L? performance to attenuate the effects of the uncertainties and to improve the accuracy of the proposed residual framers. Then, the fault sensitivity is taken into account by measuring H-performance and zonotopic residual evaluation is presented. Finally, the effectiveness of the proposed method is demonstrated by a numerical example. © 2022 IEEE.},

The design conditions of the observer are expressed in terms of Linear Matrix Inequalities (LMIs).

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. A prototype of the circuit is implemented. Experimentation results show good similarity to the theoretical simulations. © 2022 IEEE.},

abstract = {The wireless sensor network (WSN) is used to monitor environmental or phenomena physical, such as noise, pressure, motion or temperature, and to transmit data to the capital. Nowadays, with the explosive growth of IoT technology, more and more practical applications can be found in many fields, including security, smart metering, agriculture, smart cities and more domestic intelligence. There are other applications, especially military, home automation, industrial, sanitary, and especially medical applications and sanitary. This article suggests and explores home health care. The Arduino can be used to perform a portable ECG with the heart condition reading function. The main component of this system is the AD8232 sensor which can read the heart rate and process the voltage of the electrodes connected to the body. By combining the Arduino UNO microprocessor and HC 05 FC-114 as Bluetooth or Wifi, ZigBee antenna, GSM/GPRS and even XBee, the ECG screen is displayed in real time on a smartphone. We used an ECG simulator as an artificial corrective agent which is used as a tool to justify the performance of a portable ECG supported on the results obtained from the test. The EGC can be sent via the simulator to the smartphone or to the Matlab interface through a wireless communication module (ZigBee, Bluetooth, Wifi, GSM / GPRS or XBee). The exact result shows the patient's condition in real time. In this article, ECG results are published through the Matlab interface. © 2022 IEEE.},
