Random Beamforming (RBF) for mmWave systems has been proven to provide optimal performance for downlink MIMO systems with respect to the number of users and the number of antenna elements in the base station. The mobility of User Equipment (UE) and its effect on the overall system capacity has been studied as well. The duration of each frame transmitted between the Base Station (BS) and any UE depends largely on the mobility state of the UE. Static UE can receive frames with any size and duration (to achieve the optimal sum rate performance), but mobile UE is limited to a specific frame duration before that UE gets out of the narrow beam coverage area. Beam angles used by the RBF is another application specific factor in the network design and its optimization for specific conditions is required to ensure providing the best achievable throughput to each user in the network. This work is suggesting a framework to optimize the frame duration and the beam angle for each mobility model with different outage probability thresholds (when the UE is moving out of the beam coverage area during transmission or reception). Convex optimization is used as the outage probability has been proven to monotonically increase with both the frame duration and the beam angle.

RF/Microwave filters represent an important component in most modern wireless communication systems since they reject unwanted signals (noise) and pass the required frequencies. Emerging new generations and development of communication systems need for good performance and miniaturized Band Pass Filters (BPFs). Minkowski fractals used as a miniaturization technique has been applied to slotted hexagonal loop resonator for designing BPF operate at a 3.5GHz resonance frequency which is suitable for WiMAX applications. The proposed filter has been designed using FR-4 substrate with dielectric constant 4.3 and thickness 1.6mm. More than one structure has been simulated. The overall dimensions of the second iteration Minkowski fractal proposed BPF are 7.07mm x 9.88mm which is demonstrates 80.46% reduction in size as compared with conventional closed hexagonal loop resonator BPF.

Electromyography (EMG) pattern recognition has been used for different applications such as prosthesis, human-computer interaction, rehabilitation robots, and many industrial applications. In this paper, a robust approach has been proposed for High Density - surface EMG (HD-sEMG) features extraction by using envelopes of HD-sEMG signals. HD-sEMG signals have been recorded by a two-dimensional array of closely spaced electrodes. The recorded signals have been memorized in three datasets of CapgMyo database were employed to ensure the robustness of our experiment. The results display that the spatial features of Histogram Oriented Gradient (HOG) method combined with intensity features have achieved higher performance for Support Vector Machine (SVM) classifier compared with using classical Time-Domain (TD) features for the same classifier.

Different variants of LEACH algorithms are presented in the literature. A stable improved LEACH (SILEACH) algorithm, one of the LEACH variants, was proposed to overcome the problems of LEACH algorithm. Enhanced LEACH (ELEACH) and improved LEACH are other variants of LEACH algorithm which have the ability to increase the network lifetime. ELEACH utilizes distance to increase the lifetime, whereas improved LEACH increases the network lifetime using the residual energy and distance to the base station (BS). However, cluster heads selection in improved LEACH and ELEACH reduces the stability period. Generally, in many applications, network stability is considered crucial because the feedback reliability is required by the network. Recently, the SILEACH has been evaluated by assuming the BS outside the network area. In this paper, a re-evolution of the SILEACH algorithm in different environments is performed to show its effectiveness in overcoming the limitation of the ELEACH and improved LEACH algorithms. This is performed by assuming the BS inside the network area. The simulation results showed that the SILEACH significantly outperforms the two protocols in terms of the stability period and network lifetime.

This paper presents an intelligent scheme to improve the performance of the H infinity controller by selecting a suitable weighting function that ensures a robust loop shaping control. In general, the weighting function is selected by trial and error. Recently the optimization algorithms had been developed and used widely to solve complex problems and in this paper, one of the effective optimization methods (Particle Swarm Optimization) is applied to select optimum parameters of the controller that achieves robustness response against system uncertainty with good time performance. However, a good weighting function designed by selecting a suitable objective function based on combining H infinity with H2 control schemes. Simulation results confirm that the proposed control scheme satisfies the robust stability, robust performance and provide a good tracking performance in spite of systematic uncertainties and external disturbance. Moreover, the performance of the proposed controller is compared with other control methods. The simulation results illustrated the effectiveness of the proposed control method.

Iraq is one of the countries that face real security challenges. As a precautionary step, the governmental authorities have installed cameras and computers at checkpoints to facilitate monitoring of vehicles. However, such solutions are inefficient because they run manually and suffer from a lack of automation. One of the main segments of intelligent transport systems is vehicle license plate recognition, which enables the identification of each vehicle by recognizing the characters on its license plate through various image processing and computer vision techniques. In this research, a system for automatic vehicles identification and tracking is proposed. The proposed system consists of a number of distributed plate recognition subsystems that supported with cameras. These subsystems are connected to a central database to store and manage vehicles information for further processing. The proposed system is tracking all vehicles that pass through checkpoints and map them on an interactive map. The system is designed and tested in a real environment and at different times of the day. Experiments show that the system can capture the vehicle's image and recognize the license plate effectively within 2 to 4 seconds.

Plasmonic waveguides is a hot topic in the field of photonic devices due to the ability to provide signal propagation in nanoscales beyond the diffraction limit. Reducing the dimensions of optical components allows for increasing of integration density and reduce the cost of fabrication. In this paper, the dispersion characteristics of the Channel Plasmon Polaritons CPPs waveguide based on Titanium Nitride TiN material are presented. The proposed design is simulated numerically to obtain the optimum dimensions that provide longer propagation length with low loss. The asymmetric trench waveguide design shows superior performance compared to the symmetric waveguide due to the increase in the mode confinement through the groove. A 100 μm propagation length is achieved at λ = 1.6 μm by increasing the asymmetry of the trenches. TiN based waveguide provides a good alternative to the already existing CPPs waveguide designed based on gold and silver materials in terms of cost and the chemical stability. A low cost (compared to gold) and non-oxidize (compared to silver) CPPs waveguide model is proposed and simulated.

This paper attempts to show a communication strategy of implementing a hybrid of Low-Density Parity Check (LDPC) and Multiple Input Multiple Output (MIMO) based on chaotic technique. Many chaotic techniques which consider a significant part in the information security schemes was proposed, but one of the greatest defy in chaotic communications is the limitation of the system performance due to realistic channel conditions. We have investigated the theory and carried out detailed analysis pertaining to encoding/decoding of chaotic modulation schemes, the use of suitable LDPC coded MIMO schemes for providing secure and reliable communication. The aim of the hybrid scheme is that a correctly designed coded Space Time Block Code (STBC) is used to mitigate the declination of the signal caused by multipath scattering. The Bit-Error Rate (BER) performance of this hybrid scheme with two transmit antennas and two receive antennas under Rayleigh fading model is evaluated. The results indicate that that implementing LDPC (regular and irregular) coded STBC system decrease BER as compared with systems without implementing LDPC code for chaotic communication systems. Mathematical analysis for the hybrid system has been derived and achieved using Matlab.

Road markings express the rules for the road while catching the upcoming road layout. These rules are applied to driving scenarios by real drivers who are known to Highway driving manuals. However, autonomous driving vehicles must read the roads in the same way that real drivers do. In this paper, the problem of automatically reading the road markings is addressed. A new approach for lane classification using the onboard camera is presented. As an initial step, the road boundaries are detected using the Hough transform model. The region of interest (ROI) is divided into two sub-regions. Hough Transform is applied to each of the sub-regions independently. The computational time required for lane detection is improved in this way. After that, adaptive smoothing and some processing steps are added to reduce the noise while still making the close edge's apart. Then, Seed fill algorithm is applied to the lanes location to identify the lane markings types. This method is able to recognize five types of lane markings such as: dashed, solid, double solid, dashed-solid and solid-dashed. The method is applied to a large set of video sequences with various situations and showed that the accuracy is over 95%.

The simple idea of predictive control is to predict the next step of the variables behaviour of a system, then a controller is used to predict values for predefined an optimization process in order to estimate the optimum control commands. In recent years, the predictive control was used to control different drives in order to improve the performance of the controlled machines. This paper employs the Model Predictive Torque Control (MPTC) to implement multi-step prediction for stator current, stator flux in Direct Torque Control (DTC) strategy of three-phase induction motor to predict the more efficient voltage vector that drive a three-level Space Vector Pulse Width Modulation (SVPWM) inverter. The Matlab/Simulink software is used to carry the performance characteristic of a high power, 1250hp three-phase induction motor. The results reflect 12.7% reduction in torque ripple for three prediction steps compared with single.
