Electrical Vehicle (EV) is the new potential of vehicles that can solve the issues of current transportation such the air pollution, global warming, and the lack of oil supplies. However, this EV still addressed some technical problems such as unbalanced current injection to the drive motor system, especially the integrated Solar EV system. The unstable current generation from the PV system and the current injection to the drive system has many factors. One of the methods to stabilize the current trajectories in the system is by applying the closed-loop control of the Proportional Integral (PI) controller to gain feedback on non-sinusoidal current patterns in the system. The distorted current pattern can be resolved and compensate thru the fine PI tuning and improve the current pattern and resulting in a stable current injection and reduce the harmonic content supplied to the AC drive system. The operation and feasibility of the system is analyzed and validated through experimental results.

In this work, we develop upper bounds on key rates for device-independent quantum key distribution (DI-QKD) protocols and devices. We study the reduced cc-squashed entanglement and show that it is a convex functional. As a result, we show that the convex hull of the currently known bounds is a tighter upper bound on the device-independent key rates of the standard Clauser-Horne-Shimony-Holt (CHSH)-based protocol. We further provide tighter bounds for DI-QKD key rates achievable by any protocol applied to the CHSH-based device. This bound is based on reduced relative entropy of entanglement optimized over decompositions into local and nonlocal parts. In the dynamical scenario of quantum channels, we obtain upper bounds for device-independent private capacity for the CHSH-based protocols. We show that the device-independent private capacity for the CHSH-based protocols on depolarizing and erasure channels is limited by the secret key capacity of dephasing channels.

One of the alternative applications of microwave photonics is hybrid Radio over Fiber (RoF) and Visible Light communication (VLC) systems, which combines the advantages of radio frequency and optical communication together with wireless optical communication. In this paper, a hybrid radio over optical fiber and VLC system has been designed and simulated using OptiSystem Software by applying a Continuous Wave (CW) Laser at wavelength 1550 nm for optical fiber communication and 450 nm Visible Light LED for VLC system. The 8 Gbps of data was transmitted over 40 km of the fiber length and 3 m of VLC link with a Millimeter Wave (mmWave) frequency at 40 GHz. The proposed design system is analyzed based on the effect when varies the propagation distance for both fiber and VLC. The results show that as the number of fiber lengths increases, the BER performance is degraded until threshold limit 10−9. It is also shown that the proposed hybrid design system is working well even at a very high data rate of 8 Gbps for each user channel. The results also demonstrate that Non-Return Zero (NRZ) modulation technique has contributed to the better performance of the systems compared to Return Zero (RZ).

Optical CDMA is a technique based on the same principle of CDMA, in which each individual user is assigned by a unique code. OCDMA consists of distributing the power of the transmitted signal across an enormously wider bandwidth which is necessary to transmit the information. In fact, OCDMA offers a significant role in optical fiber communication due to several attractive characteristics such as dynamic bandwidth assignment, high security, low cost, low interference, and flexible quality. On the other hand, WDMA is a technique that provides a division of the optical channel into subchannels. In this paper, an investigation of the performance of a hybrid WDMA-OCDMA system based on Laguerre Gaussian modes has been illustrated. The analysis is done by using 2D ZCC/MD code according to its success demonstrated in various investigations. 2D ZCC/MD code is distinguished by a property of zero cross-correlation which affords a capability in order to reduce receiver noise and Multiple Access Interference (MAI). In addition, 2D ZCC/MD code proved an ability to improve the system performance in terms of cardinality and other factors that can affect the system. The transmission is done over multi-mode fiber (MMF) which can be applied in a short haul-local area network. Furthermore, the system is implemented based on Three different Laguerre Gaussian modes (LG 01, LG 02, and LG 03). The evaluation of the system performance is done based on Bit Error Rate (BER), Q-Factor, and eye diagrams measurement.

The usage of the textile antenna for diverse applications have been empowered by the miniaturization of wireless systems for the Fifth-generation technology (5G), and it has become one of the world's fastest developing technologies presently. However, the textile antenna when placed on human body goes through different bending and its performance gets altered. This paper presents design of two different textile antenna using polyester and denim as the substrate materials, where the radiating element and the ground is made from copper tape. The comparative study of polyester and denim textile antenna under various bending conditions due to non-identical human upper arm sizes (large, medium and small) for 5G mid band frequency has been analyzed. The analysis is presented comparatively from the simulated and optimized result using Computer Simulated technology (CST) which focuses on the value of gain, antenna efficiency, bandwidth and directivity. It has been observed that denim textile antenna has covered desired frequency of 3.5 GHz with bandwidth of 140 MHz to 154.7 MHz in all the different bending conditions. Moreover, denim textile antenna obtained gain value above 2 dB in all the conditions. For polyester textile antenna, although it has covered 3.5 GHz during flat condition however as the bending angle increased, its resonance frequency shifted away from 3.5 GHz with insufficient bandwidth and low gain. At extreme bending of 72°, for both the antennas, there was frequency shifting in lower bands by 88.9 MHz (2.54%) for denim while it was 148.5 MHz (4.2%) for polyester.

AIP Conference Proceedings 2024年第1期3135卷

作者： Safa Ali Abdo Hussein R. Badlishah Ahmad Naimah Yaakob Abdul Ghani Khan Faculty of Electronic Engineering & Technology Universiti Malaysia Perlis Pauh Putra Campus 02600 Arau Perlis Malaysia Faculty of Engineering and Information Technology Taiz University Taiz 6803 Yemen Centre of Excellence for Advanced Computing Universiti Malaysia Perlis (UniMAP) Perlis Malaysia School of Computing and Communication Lancaster University Bailrigg Lancaster LA1 4WA United Kingdom

Support Vector Machine (SVM) modelling approach focuses on dimensional reduction with a powerful generalization capability to solve problems such as non-linearity, and local extremes. However, the ability of SVM to learn and generalize depends on the collection of acceptable parameters that directly affect the output of the model. In addition, deploying relevant feature sets is also an issue in obtaining optimal classification. Thus, this work deploys eight swarm intelligence algorithms to improve the SVM classifier’s accuracy by conducting two experiments: feature selection and tuning SVM parameters using the obtained feature set. The deployed swarm intelligence algorithms include Particle swarm optimization (PSO), Genetic Algorithm (GA), Firefly Algorithm (FA), Salp Swarm Algorithm (SSA), Bat Algorithm (BA), Sine Cosine Algorithm (SCA), Whale Optimization Algorithm (WOA), and Multi Verse Optimization (MVO). The undertaken experiments were on six medical benchmark datasets that are of various dimensions. Evaluation was based on two metrics: classification accuracy and size of feature set. This work’s significance is to present the comparison and determine which swarm algorithm is the best to be used in a large size medical dataset. The experimental results support existing literature that noted the swarm intelligence are useful feature selection as well as optimizing SVM parameter while maintaining acceptable accuracy.
