This study introduces a quantum-behaved lightening search algorithm (QLSA) to improve the search capability of every step leader to find a projectile position. The QLSA improves the indirect field-oriented fuzzy-PI controller technique to control a three-phase induction motor (TIM). The generated adaptive PI current control parameters and fuzzy membership functions (MFs) are carried to design induction...
Recently, a considerable attention has been paid for full duplex communication. Full duplex allows transmitting and receiving at same frequency simultaneously. As a result, the spectral efficiency can be increased two times by utilizing this type of communication. Nevertheless, the substantial issue of applying full duplex communication is the self-interference signal. This paper presents a new method...
This paper examines the benefits and drawbacks of these services, reviewing differences in infrastructure, power requirements, sensing devices, and other factors. Technologies covered include Radio Frequency Identification, GSM, GPS, A-GPS, Smart Antennas, Distributed Antenna Systems, Localization by Cell-ID, Localization by Prediction (Dead Reckoning method), Angle of Arrival (AOA), Localization...
Sophisticated embedded systems are increasingly used in defence, aerospace and avionic industries. They are responsible for control, collision avoidance, pilot assistance, target tracking, navigation and communications, amongst other functions. In this industrial field, High Performance Embedded Computing (HPEC) applications are becoming highly sophisticated and resource consuming for three reasons...
Learning From Demonstration (LfD) is an important area of research in robotics because it provides the means for skill transfer from humans to robots with no reliance on any specific technical skills of the human teacher. There are many approaches to LfD. Most available methods assume the existence of clear boundaries between different demonstrations. Less research focuses on techniques that can be...
We present a plasmonic absorber of Fabry-Perot-like resonator and demonstrate the tuning capability of its spectral response. The conventional resonator comprises two spaced layers of gold to act as a confinement for the light and resonant structure. The cavity thickness can be used efficiently as a tuning parameter for the absorber frequency response. The unloaded absorber shows high absorption greater...
Sorting algorithms are one of the most commonly used in computer science. They can be seen as a pillar for some applications such as decision support systems, path planning, etc. However, sorting large number of elements needs high computation rate. Consequently, accelerating sorting algorithms using hardware implementation is an interesting solution to speed up computations. The purpose of this paper...
Metal-halide perovskite solar cells attracted more interest in last decade due to rapid enhancement in its efficiency from 3.9% in 2009 to over 20% in 2016 [1]. In this work, we studied theoretically effect of using silver nanostructures inside active layer of perovskite solar. Metal nanostructures could confine and guide electromagnetic waves at nanoscale dimensions, however these processes are highly...
In computer science, specification language is defined as a formal language used during systems analysis, requirements analysis and system design to describe a system. This description will be at much higher level than programming, which is used to produce the executable code for a system. Formal specification language provides mathematical representation of the system and expresses the specification...
This paper presents a new lane tracking algorithm for the lane departure warning system without using Kalman filter. The system is capable of extracting the true lane boundaries from all detected lines including noise in the frame and estimates its future position. The new algorithm uses the score mechanism to trace the appearance of lines in previous frames using a score variable which indicates...
The frequency spectrum is an expensive and limited resource while the massive demand of telecommunication services both of data and number of connection continue to raise. The ordinary network becomes denser to meet the growing needs of the services. It can be done by introducing more cells in the network, with lower coverage than the ones that already exist or simply by splitting the existing cell,...
This work aims to improve the power generation by applying and experimenting a new technique of Radio Frequency (RF) energy harvesting using products of Powercast. This energy is used to activate a Light-Fidelity (Li-Fi) sample device and charge an energy storage system simultaneously. The final outcome of the system is now able to activate the Li-Fi sample device and charge a battery system at the...
This paper focuses on the design and performance of sampled-data robust control of a class of continuous-time underactuated electromechanical systems. The control law is designed on the philosophy based on stabilization of discrete-time equivalent model of a continuous-time system which can be broadly classified into sampled-data stabilization of a class of underactuated linear systems with a time-varying...
Selecting a classification model to deploy in educational systems is a very sensitive process since it is necessary to guarantee that the model will work well after being deployed in a real situation and at the same time the model needs to be friendly to the users involved in the educational settings. The goal of this paper is to select an accurate and easy-to-understand model to serve as a basis...
This paper studies a dual-band antenna and a rectifying circuit that can be integrated together with the aim of harvesting enough power for the operation of an implantable glucose sensor. A capacitively-loaded printed inverted F-antenna (IFA) on a flexible thin Liquid Crystal Polymer Rogers substrate in addition to a schottky-diode based single stage rectifying circuit were designed and simulated...
A wireless power transfer system based on the concept of Near-Field Focusing is proposed. MUltiple Signal Classification (MUSIC) algorithm is used for localization and tracking, 2-D array of identical elements working at 2.4 GHz is used to focus the beam at the targets to be charged which are located in the near-field of the array. The proposed system ensures the delivery of a sufficient amount of...
Evolutionary optimization techniques with multiple objectives are applied to the design of microstrip antennas. The biologically inspired algorithms, Particle Swarm Optimization, Genetic Algorithms and the Firefly Algorithm, are integrated in new software, Antenna Optimizer, which combines attributes of the electromagnetic design environment of CST Microwave Studio with those of the technical computing...
One of the objectives of the control using the human thought is to make useful robotic systems for persons with high dependency (quadriplegics, paraplegics, etc.). When the human subject is not able to move his limbs, upper or lower, he is no longer able to perform basic and necessary tasks in his daily life. Recently, robotic systems have reached a very advanced level. For example, humanoid robots...
This paper addresses the problem of detecting and tracking multiple moving people when the scene background is not known in advance. We have proposed a new background detection technique for dynamic environment that learns and models the scene background based on K-mean clustering technique and pixel statistics. The background detection is achieved using the first frames of the scene where, the number...
