In modern electronic systems, signal stability is a crucial issue. Many methods have been developed to mitigate the deviation from an ideal signal. One of them is called Automatic Gain Control, which tracks variation in an input signal to settle output amplitude. This paper proposes a Differential Automatic Gain Controller with offset stability. It is a Proportional Integral Derivative controller...
In this paper, a Ultra-Wide-Band (UWB) antenna of dimensions 3cm × 3cm, designed to be used in direct contact with the breast is presented. The breast phantom model, on which the antenna was designed, consists of four layers (skin, fat, glandular tissues and muscle with their specific thicknesses) taking into account the dielectric properties for each layer and their dependence versus frequency. The...
The paper proposes a preliminary study that aims to investigate the efficiency of the moving element method MEM which is largely used in the literature when solving high-speed moving load problems. Among other, the train/track interaction problem is considered as the main cause of the environmental perturbations that are less and less tolerated by inhabitants. The target is to find a reliable response...
The truck lines, which is an mounting of pipes, is automatically send in to a non-destructive testing technology (X-ray radiography or γ ray technology) that allows us to check and guarantee the quality of the new oil pipeline. Advanced techniques for this type of control are set to apply a robot Crawler inside the pipeline with a very advanced technology to help us to diagnose the pipelines very...
In recent years, malls containing a concentration of shops and restaurants flourished in cities all over the world. This concentration is the cause of problems in parking spaces and traffic jams. This paper introduces a parking management system using mobile application to address the parking problems in malls. The contribution in this system is two folds. The hardware part which consists of custom-made...
In this paper a miniaturized Substrate Integrated Waveguide (SIW) liquids sensor is presented. Half-Mode (HM) miniaturization technique is applied on the SIW resonator cavity. Sensor area is reduced by 50% in comparison to the conventional resonator. The complex permittivity is calculated using artificial neural network. The sensor is fabricated, experimental results shows acceptable matching with...
This paper presents a new application for Slow-wave Microstrip (SMS) technique in miniaturization of rectangular patch antennas. The designed patches resonate around the Industrial Scientific and Medical (ISM) radio bands, 2.45 GHz, and were optimized using HFSS. The SMS design technology used is based on the insertion of via holes within multilayer substrate. The simulation results show that the...
Recent years have witnessed rapid growth in medical applications based on wearable devices and sensors, which is attributed mainly due to the progress in wireless technologies and antennas. As the mobility and compactness of medical devices are becoming more demanding, wearable wireless sensors and antennas become an important candidate with their compact size, light weight, and ease of integration...
The failure of the main grid to feed its load demand continuously and the high cost of fuel consumption taken by the individual generators, push us to start thinking about a solution. Moreover, the pollution of its different kinds and their consequences due to the high use of fossil fuel dependent machines and the global uninterrupted increasing in the fuel cost are also a problem. One solution is...
Many studies in different domains have shown the possibility of extracting information from a medium by exploiting the natural acoustic noise present in such medium. Recently, the promising potential of a passive acoustic technique, based on the correlation of the ambient noise for controlling the state of the structures has been shown. The position of the acoustic source should be determined at the...
This paper presents the use of the Geographic information for data management and visualization in a smart city project (SunRise — Smart City), conducted at the Scientific Campus of the University of Lille. The campus stands for a small town with around 25 000 users. It includes 150 buildings and 100 km of urban networks. Arc GIS is used for the management and visualization of data concerning the...
Recent advances in intelligent water meter technology have improved the quantitative monitoring in water supply and distribution. Smart meters using Automated Meter Reading (AMR) technology allowed water utilities to: i) provide clear consumption patterns which can help customers to track and control their water usage and ii) improve active leakage targeting and leak detection capability. This paper...
Small antennas have characteristics that limit their performance such as low radiation power, increased losses in the matching network and a narrow bandwidth. We examine theoretically the possibility of miniaturization and the improvement in efficiency of dipole antennas by replacing the normal conductors with bulk high-Tc superconductors. These antennas are useful especially in the radio frequency...
Head pose estimation has been a focus of research in computer vision both implicitly in tasks that use full body pose estimation, and explicitly in tasks that perform face tracking and face recognition. One of the main problems in the field of face recognition techniques is the difficulty of handling varying poses. In this work, we propose a robust pose estimation approach that represents the relationship...
Recently, Terahertz technologies, due to the extensive research and tremendous progress achieved in the field of Terahertz radiation, promise countless potential applications in the fields of security and defense. A particular interest is the development of new technologies that enable the identification of concealed prohibited drugs. This paper surveys the existing research which investigates the...
Solar energy can reduce the need of fossil fuel and ensures energy security for many countries. Solar tracking significantly improves the collection of solar energy by reducing the angle of incidence on the collecting surface. The present research introduces an optimized solar tracking system that enhances the output power of photovoltaic panels. The tracking system implements a hybrid control strategy...
Mobile workflow execution is gaining importance as the interaction among mobile devices, IoT and cloud becomes ubiquitous. Unfortunately, the instantiation of mobile security controls has not evolved as fast as current mobile applications and services, in part because of the tight coupling between these controls and the mobile workflow's execution platforms underneath these applications and services...
