The Electric Vehicles (EVs) are garnering immense attention in recent times, since they support sustainable transportation with minimized carbon emission. The amount of carbon footprint released to the atmosphere is further reduced with the adoption of Photovoltaic (PV) based EVs. The PV output is initially fed to a DC-DC SEPIC converter, which produces high dc voltage with non-inverting output and reduced switching loss. The operation of the SEPIC converter is controlled using a Hybrid Grey Wolf Optimization (GWO)-Particle Swarm Optimization (PSO) based Proportional Integral (PI) controller for providing a stable DC voltage to the three phase Voltage Source Inverter ( 3𝜑 VSI). The 3𝜑 VSI output is used to power the BLDC motor of the EV. The power from the PV is sufficient for the EV application during daytime, however, during night time with the absence of the sun, the BLDC motor is supplied with the power from the grid. The grid is connected to this system through a Single Phase (1 𝜑 ) VSI. The proposed control method is verified using MATLAB simulation and the hybrid GWO-PSO algorithm delivers an outstanding efficiency of 96%.
电动汽车(ev)最近受到了极大的关注，因为它们支持可持续交通，同时将碳排放降至最低。由于采用了基于光伏(PV)的电动汽车，排放到大气中的碳足迹量进一步减少。PV输出最初被馈送到dc - dc SEPIC转换器，该转换器产生高直流电压，无反相输出，减少开关损耗。采用混合灰狼优化(GWO)-粒子群优化(PSO)的比例积分(PI)控制器控制SEPIC变换器的运行，为三相电压源逆变器(3 -变量VSI)提供稳定的直流电压。3个变量的VSI输出用于为电动汽车的无刷直流电机供电。来自PV的功率在白天足以满足EV的应用，然而，在没有太阳的夜间，无刷直流电机由电网供电。网格通过单相(1变量)VSI连接到该系统。通过MATLAB仿真验证了所提控制方法的有效性，结果表明该混合算法的控制效率高达96%。

Nonorthogonal multiple access (NOMA) is a promising multiple access (MA) technique for next-generation wireless systems with its capability to offer higher spectral efficiency, supporting massive network elements and low latency. Single-carrier frequency division multiple access (SC-FDMA) can be combined with NOMA systems to improve spectral efficiency and user capacity. This study proposes a transceiver structure for SC-FDMA based NOMA systems using discrete wavelet transform (DWT). The proposed transceiver structure employs joint discrete Fourier transform (DFT) precoding and DWT to obtain a higher bit error rate (BER) performance over conventional systems. The proposed scheme is referred to as a joint DFT precoded DWT SC-FDMA NOMA system that benefits through outstanding orthogonality and spectral containment characteristics of DWT, thereby improving the performance of the SC-FDMA NOMA system. Moreover, we have investigated the performance of the proposed system with variations in carrier frequency offset (CFO) to show the supremacy of the proposed SC‐FDMA NOMA System over multipath channels.

Past computerization and control, advanced robotics and autonomous systems (RAS) are interconnected, intuitive, mental, and actual devices, ready to differently see their surroundings, reason about occasions, make or change arrangements, and control their activities. They are partners that work close by us to perform valuable errands with and for us in reality, broadening our capacities, decreasing our dangers, and increasing our efficiency. RAS might be considered the eyes, arms, and legs of large amounts of information, seeing, deciding, and making a move. When interconnected, for instance, inside the 'web of things', the actual effect of RAS can be gigantic. Independent frameworks don't need to implement a "physical" activity through a robot. They can also decide and act within computerized frameworks, such as financial trades [1].

. In recent years, for robot structural design, the conventional materials are replaced by alternative nanocomposite materials for its enhanced properties. This paper describes the impact of Nanoclay reinforced AA 5083 as a novel material replacement for the design of redundant SCARA (RSCARA) robot by varying the composition of Nanoclay in weight percentage (0, 1 and 2 wt%). The RSCARA parts are modelled by three dimensional (3D) computer aided design (CAD) modeling Solid Works package by imparting the material properties of newly developed nanocomposites. The model developed was exported to MATLAB/ Simscape Multibody Simulation environment and converted into multibody electromechanical system blocks. The required Input/output primitives are consigned for the joint blocks and the dynamic parameter torque was derived by the Simscape Multibody simulation. The results of the simulation regarding the dynamic performance obtained for RSCARA solid and round hole perforated manipulator main arm and fore arm links assigned with Nanoclay reinforced AA 5083 material is expressed in this research work.

This paper presents a novel Modular Multilevel Converter–DSTATCOM topology used to integrate PV system into the AC Grid. Unlike the conventional MMC topologies, the proposed topology can be applied in high power applications requiring more voltage levels using less capacitor count maintaining higher efficiency. The common problem caused within a MMC by the impact of circulating current is eliminated here by adding it with the input current of each arm. Photovoltaic (PV) System generally uses Power electronic converters to convert the generated DC into AC by switching ON and OFF of the Power electronic devices. This leads to the introduction of Harmonics into the power system causing deterioration in the power quality resulting conductors heating, malfunctioning of fuses, circuit breakers and relays. This paper introduces an Adaptive Radial Basis Function Neural Network (RBFNN) based on the Synchronous Reference Frame (SRF) theory which is capable of generating the compensating reference current needed to extract the total harmonics from the system. It uses a deep learning filtering algorithm based on a hybrid learning method, which is regarded as the computationally efficient training method with less complexity and negligible training time. Extensive simulations are carried out in MATLAB software and its performance in each aspect is analyzed by comparing it with conventional methods. The results obtained show the usefulness of the novel topology and the proposed algorithm in improving power quality.
