The system employs a microprocessor-based control mechanism to enhance functionality and precision, implemented with an Arduino bash, a brushless DC (BLDC) motor, and an electronic speed controller (ESC), which permits very fine control of motor speed by employing pulse width modulation (PWM). So with the introduction of PWM signals, the ESC operates perfectly. This configuration demonstrates efficient PWM-based motor control and provides a workable solution to many control and automation problems. For instance, speed control between an Arduino and a BLDC motor is possible. A user finds it easy to operate with a potentiometer that interfaces with the system to adjust the speed of the motor. By presenting system information, a liquid crystal display (LCD) monitor enhances user participation by providing feedback instantly. The patient self-management unit is powered by a LiPo battery to ensure steady and reliable operation at all times. This configuration does illustrate efficient motor control through the use of PWM but also provides a viable alternative for a range of control and automation systems.

Abstract This work presents a novel peak-to-Average aower ratio (PAPR) reduction method for non-orthogonal multiple access (NOMA) waveforms based on an Airy function-based partial transmit sequence (PTS) strategy. The new approach is evaluated over NOMA systems with 64, 256, and 512 subcarriers and compared with traditional PTS, selective mapping (SLM), and clipping and filtering methods. Performance assessment takes into account significant parameters such as PAPR reduction, bit error rate (BER), and power spectral density (PSD). Findings show that the Airy-based PTS scheme efficiently reduces PAPR for all subcarrier configurations with a competitive BER, especially in high-subcarrier applications where conventional methods tend to deteriorate. PSD analysis also verifies that the suggested method maintains spectral integrity, reducing out-of-band emissions. Such a conclusion makes Airy-based PTS a promising means of improving the efficiency of NOMA waveforms in 5G and forthcoming wireless networks via an optimal performance balance between spectral efficiency, reduction of PAPR, and BER performance.

Abstract This work presents a neural network-based framework for peak power suppression and throughput enhancement in optical OFDM systems employing 1024-QAM modulation for high-capacity computer networks. Optical OFDM signals inherently suffer from high peak-to-average power ratio (PAPR), which leads to nonlinear distortions in the optical channel and degrades bit error rate (BER) performance. To address this challenge, a convolutional neural network (CNN)-based scheme is proposed and evaluated under different subcarrier configurations. The analysis demonstrates that the proposed method consistently achieves significantly lower PAPR values, recording only 1.8 dB, 3.5 dB, and 5.5 dB at a complementary cumulative distribution function (CCDF) of 10 −3 for 64, 256, and 512 subcarriers, respectively. In comparison, conventional schemes such as SLM, PTS, SVM, and RNN exhibit considerably higher PAPR levels. Similarly, BER performance analysis shows that the proposed method achieves target BER of 0.001 at 7 dB and 9 dB SNR for 256 and 512 subcarriers, representing up to 13 dB improvement over traditional techniques. These results confirm the robustness, scalability, and efficiency of the proposed NN framework in reducing peak power and improving signal reliability. The findings highlight its potential for integration into next-generation optical communication and computer networking systems requiring high spectral efficiency and energy efficiency.

Internet of Things isn’t always approximately about the things themselves; it’s approximately being clever. IoT is real and helpful because of its ability to apply intelligence to sense facts, especially in the context of construction engineering. A smart building’s architecture is a great place to start as IoT is reshaping every aspect of a building, from design to occupancy to maintenance. The experience of workers, control, and tenants is being optimized through the use of IoT data to inform decision-making. Better facilities may simplify corporate processes and increase revenue in smarter homes. The goal of intelligent houses is sustainability. There are several methods for automating tasks with the Internet of Things. It is necessary to address every single facet of the building architecture. This article discusses the problems and technologies of IoT-based smart building architecture. The Internet of Things (IoT) and embedded systems provide the foundation of the “Smart Building” idea. Together with smart lighting in smart buildings and seismic detection, the model that is being shown has several features. When the smart lighting system turns on and off, it is determined by the amount of natural light available and the presence of people within the building. In order to reduce the amount of maintenance needed, smart dustbins that open up when they sense a person are available. Watering systems that are designed to measure the moisture content of the soil are extremely useful for the maintenance of lawns. A seismic activity detection module allows for early warnings of earthquakes and other seismic activity that may occur in the future. It has been successfully developed a smart building concept that uses Arduino and a cloud server to analyze the data gathered from the smart building.

This study investigates the utilization of waste steel chips as reinforcement in aluminum-based composites through the stir casting technique. Steel chip particles were introduced gradually into the molten aluminum alloy while stirring at 400 rpm for 10 minutes to ensure uniform dispersion. Precise temperature control prevented premature solidification, facilitating effective incorporation of steel chips. The resulting composite exhibited a predominantly uniform distribution of reinforcement, indicating successful processing.The addition of 7.5% waste steel chips led to remarkable improvements in mechanical properties. Tensile strength increased by 15.67%, while hardness showed a substantial enhancement of 25.56% compared to the base composite. Moreover, wear resistance exhibited a notable improvement of 19.45%. These enhancements underscore the efficacy of waste steel chips as reinforcement, revolutionizing manufacturing practices in aluminum composites. The findings highlight the potential for sustainable and cost-effective approaches to enhance mechanical performance, contributing to advancements in materials engineering and promoting eco-friendly manufacturing practices.

This paper aims to devise an antenna structure tailored for seamless integration into aviation radar sensors. The primary design objectives entail the creation of an antenna resonating within the X-band frequency range, spanning from 8 GHz to 12 GHz, with a central frequency of 9.79 GHz, while prioritizing portability. A meticulously dimensioned unit cell is engineered to achieve these specifications, resulting in an antenna design operating at 10.36 GHz. Key parameters including S11, Gain, Efficiency, and Radiation characteristics are meticulously assessed. Subsequently, these unit cells are arranged in serial and parallel configurations and analyzed across various metrics. Noteworthy findings reveal that the parallel array design exhibits superior radiation performance at 10.3 GHz. In contrast, the serial array configuration demonstrates enhanced attributes, including higher gain and improved S-parameter characteristics, particularly at 10.8 GHz. The input impedances were readily adjusted to match 50-ohm feedlines. The antenna design leverages dielectric materials such as Duriod for the substrate and copper for the patch and ground components. Specifically, the Duriod substrate boasts a dielectric coefficient of 2.2, with a substrate thickness of 1.57 and a copper thickness of ${0. 0 3 5}$. This investigation underscores the efficacy of the serial array antenna design, highlighting its potential for optimal performance in aviation radar sensor applications..
