Abstract :

This study proposes a novel approach to power flow control in on-grid hybrid microgrids by combining AC-DC microgrids with a modified unified phase-to-phase power controller (UIPC). The AC microgrid and the DC microgrid represent a hybrid system that is normally connected to the grid. Instead of power converters connected in parallel, these microgrids are connected to one another via a modified UIPC. The first contribution of this thesis is a modification of the UIPC standard, which makes it possible to control the energy exchange in AC-DC microgrids with fewer power converters than three are required in each phase of the conventional UIPC structure. LPC control methods use an artificial neural network (ANN) controller. Using the H∞ filter method, the ANN tool is optimized to eliminate format errors in the membership functions. The DC microgrid is used to supply the LPC with the required DC voltage via the BPC. After successfully powering the DC microgrid with a photovoltaic instrument, LPC #039; The intermediate circuit voltage changes. For the DC- -BPC, the NDO-MS-SMC (Strate Strong Absolute Multi-Mass Slip Mode Control) strategy is available to stabilize the DC link jitter, which is based on the observation of non-linear disturbances. The simulation results demonstrate the effectiveness of the proposed energy management strategy in combination with the flow control technique for smart grids in Advanced UIPC. An artificial neural network (ANN) is used to adapt UIPC converters; this is proposed in this study as a comparable extension.

Abstract :

The most vulnerable groups to falling asleep behind the wheel include shift workers, business car drivers, and truck drivers. The majority of collisions are caused by intoxicated drivers. Since the business owner is held accountable, the burden falls on them. It can result in financial loss. We demonstrate an adaptive driver and business owner alert system in this presentation, together with an application that informs the business owner about their driving habits. The two main factors that cause serious accidents that result in injuries, fatalities, and property damage are alcohol use and drowsiness. We recommend a system that makes use of a variety of sensors to address this issue. These sensors are utilised for seat belt monitoring, drowsy driver detection, and alcohol detection. The buzzer is used to warn the driver if they feel sleepy, their seatbelt isn't fastened, or alcohol is detected. The motor stops whenever the sensor values fall outside of the threshold value range. In an emergency, the GPS module pinpoints the location and sends this information to the designated person or person in charge of the ward through GSM. Cortex M3 will have complete control over the entire system. By warning the motorist, this technology can help to reduce serious traffic accidents.

Abstract :

Flyash blocks made of autoclaved aerated concrete (AAC) are lightweight employed quickly in high-rise structures. One of the sustainable materials is the AAC Block, which is made from fly ash from industrial waste. AAC block masonry in fills contribute to a structure's low weight, thermal conductivity, and speed of construction. To increase the effectiveness of the AAC block masonry, material level research is required. The literatures lack a awareness of the material level of behaviour of AAC block construction. In order to comprehend the compressive stress-strain behaviour of AAC Block masonry and its components, experimental study is described in this work. Compression testing is used to determine how well AAC block masonry responds to weak and strong mortar.

Abstract :

A Stock Market is a place where company shares are traded to stockbrokers. Stock price prediction is one of the most challenging problems as a high level of accuracy is the key factor in predicting a stock market. Many methods are used to predict the price in the stock market but none of those methods are proven as a consistently acceptable prediction tool due to their volatile nature. The stock market prediction has been one of the popular topics in the financial domain. Prior to the advancement in Machine Learning and Artificial Intelligence, many Statistical models were employed. Even though these models gave almost accurate results but using these models was not efficient and time-consuming because of the market’s rapidly changing behavior. Due to the advancement in Machine Learning and Artificial Intelligence, it has become possible to employ different models like Neural Networks, Regression, Decision Trees, etc. which give us results as accurate results as Statistical Models if not better in a very short amount of time. This paper, going to make use of an artificial neural network (ANN) model with backpropagation to forecast stock prices. ANN can generalize and predict data after learning and analyzing the initial inputs and their relationships. A feed-forward network and backward propagation algorithm is used to predict stock prices. This research work introduced a method that can find out the future value of stock prices on a particular day and also predict a bullish or bearish market based on the current price using the ANN backpropagation algorithm.

Abstract :

Steganography is one of the essential techniques in cryptography to transfer data securely over internet. In this technique, the digital images are used as a cover to relay sensitive information. The Least Significant Bit (LSB) method is one of the simplest ways to insert secret data into a cover image. The goal of this research is to offer a new image steganography approach based on chaotic cryptography. The selection of pixel position in the cover image is the most important security feature of the proposed approach. This chaotic based steganography method uses pseudo-random numbers generated through logistic map to select pixels in different size of images. The data has been embedded in the least significant bits of Red (3), Green (2) and Blue (3) positions of random pixels of image. This proposed adaptive stegano technique is validated for the quality of algorithms using the Peak Signal Noise Ratio (PSNR) and Mean Square Error (MSE) measurements.

Abstract :

DDoS attacks, which target a network as a whole, are the most common name for these kinds of attacks. The attacks make use of weak spots in the authorised group's website framework, for example, to get unauthorised access to sensitive information. The author of the current study used a legacy KDD dataset in his or her research. If you want to know where DDoS attacks stand right now, you need to use the most recent available dataset. In this research, we employ a machine learning technique to classify and forecast DDoS assault types. The classification methods Random Forest and XGBoost were utilised for this purpose. A comprehensive paradigm for DDoS attack prediction was provided in this study. The suggested work makes use of a Python simulator built on top of the UNWS-np-15 dataset, which was obtained from the GitHub source. Following the implementation of the machine learning models, a confusion matrix was created to evaluate the accuracy of the predictions. For the initial categorization, the Random Forest method achieved an impressive 89% in both Precision (PR) and Recall (RE). Our proposed model has an Accuracy (AC) of 89%, which is excellent and more than sufficient. Both Precision (PR) and Recall (RE) for the XGBoost algorithm hover around 90% in the second classification. Our proposed model has an Accuracy (AC) of 90% on average. We found that the accuracy of defect assessment was significantly increased, from around 85% to 79%, when compared to prior study.

Abstract :

As a new subfield of neural networks, deep learning has proven to be highly effective at tackling difficult learning challenges. It is becoming increasingly difficult to build high-performance solutions of neural networks with deep learning as the dimension of the nodes grows in response to the needs of actual applications. In this study, we propose a deep neural accelerator unit (DLAU), a scalable accelerating architecture for large-scale neural networks using deep learning that uses field-programmable gate matrix (FPGA) as the computer chip prototype, to achieve both performance gains and reduced power consumption. The DLAU accelerator uses tiling approaches to investigate locality in deep learning applications and makes use of three pipelined computing units to increase throughput. The DLAU accelerated is capable of speeds comparable to those of Intel Core2 CPUs, as shown by experiments conducted on a cutting-edge Xilinx FPGA board. Index Terms-Deep learning, field-programmable gate array (FPGA), hardware accelerator, neural network.

Abstract :

The increasing complexity of the DSP systems demanding higher computational performance in its architecture. But the traditional DSP arithmetic has limits in terms of speed of calculations. More over in some applications speed is more important than accuracy. In order to further enhance performance, approximate arithmetic circuits are designed with some loss of accuracy to reduce energy consumption and increase the speed. These approximate circuits have been considered for error-tolerant applications. In this paper, we propose an FIR filter based on Rounding Based Approximate (ROBA) Multiplier. In this multiplier the operands are rounded to the nearest exponent of two. This approximation will lead to simplification of multiplication operation thus reducing area and increasing speed. As the multiplier is the slowest element in the system, it will affect the performance of the overall FIR filter. The proposed ROBA multiplier based FIR filter was compared with HAAM and DRUM multiplier based FIR filters. The results shown significant reduction in the power and area of the FIR filter with proportional improvement in the multiplier speed. The Filter was implemented and tested using Virtex 5 FPGA at an operating voltage of 1.0V using Xilinx ISE environment.

Abstract :

Forecasting the amount and pattern of precipitation (rainfall) in a certain geographic area for a set time period, usually in the near future, is known as rainfall prediction. For many purposes, including farming, managing water resources, flood control, and disaster management, accurate rainfall projections are crucial. Establishing models of prediction that can predict future precipitation requires the use of past meteorological data and machine learning techniques. Weather patterns are often non-stationary, meaning they change over time. Machine learning models assume stationarity, which can be a limitation when dealing with climate and weather data that exhibit trends, seasonality, and long-term shifts. The proposed model uses Blended stacking model, is a technique in machine learning where multiple models are combined to improve predictive accuracy. Stacking can make rainfall prediction models more robust to changes in data distribution and weather patterns. It can adapt to varying conditions and provide consistent performance over time.Blended stacking can provide not only point predictions but also measures of uncertainty. By aggregating predictions from multiple models, it can offer insights into the variability and confidence associated with rainfall forecasts.

Abstract :

Objectives: India has experienced a rapid escalation of overweight and obesity rates, surpassing the global average. Obesity has emerged as a significant health concern with multiple contributing factors, including biological, genetic, social, environmental and behavioral influences. Among adolescents worldwide, obesity is a prevalent issue and poor dietary habits are considered to be the fundamental risk factors for many chronic diseases such as type II diabetes, cardiovascular disease, cancer and obesity. To address these complex problems, the use of Machine Learning (ML) techniques can facilitate the identification of patterns and factors of obesity by analyzing extensive nutritional epidemiology databases. The main aim of this study is to perform multi-class classification of obesity of adolescent girls using an ensemble of ML classifiers. Methods: A primary dataset of 2000 adolescent girls, gathered from schools and colleges in Chennai, India are input for this study. Our study investigates the obesity using ML classifier algorithms by employing 75% of the dataset for training and the remaining for testing. We have applied eleven well-known algorithms to compare and evaluate their prediction accuracies using the training and testing datasets. To assess the performance of the classifiers, the metrics such as precision, recall /sensitivity and F1-Score have been calculated and analyzed for predicting the actual outcomes. Findings: Based on our computer experimental results, the CatBoost algorithm has achieved the highest accuracy of 90.6%, when we compare with that of other classifiers. Novelty: The uniqueness of our study is collecting and analysing the primary dataset which is focused on adolescent girls, age ranging from 16 to19 and classifying the dataset using various ML algorithms. But, the most of the other studies are not focusing on this specific age group for predicting the obesity. By understanding the factors contributing to obesity in adolescent girls, the researchers can study the long-term health impacts and help the society to prepare better for future healthcare challenges.

Abstract :

Radiotherapy planning is a critical aspect of cancer treatment, where the optimal selection of beam directions and dose distributions significantly impacts treatment efficacy and patient outcomes. Traditionally, this process involves time-consuming manual trial-and-error methods, leading to suboptimal treatment plans. To address this challenge, optimization strategies based on advanced artificial intelligence (AI) techniques have been explored. This paper presents an investigation into the application of AI-driven optimization methods for beam direction and dose distribution selection in radiotherapy planning. The study proposes an approach utilizing Convolutional Neural Networks (CNN) to learn the relationship between patient anatomy and optimal beam orientations. The CNN model is trained on a dataset comprising anatomical features and corresponding beam orientations, derived from a column generation (CG) algorithm. Additionally, Particle Swarm Optimization (PSO) and Grey Wolf Optimization (GWO) algorithms are employed to optimize the CNN's weights and biases to attain the Fluence Map Optimization (FMO) objective function. Experiments are conducted using data from 70 clinical prostate cancer patients. The results demonstrate the effectiveness of the CNN-PSO and CNN-GWO approaches in generating beam orientations that yield treatment plans with dose distributions comparable to those obtained through traditional CG. DVH analysis of the resulting plans for different anatomical structures validates the accuracy and feasibility of the CNN-GWO model in radiotherapy planning. The findings of this study highlight the potential of AI-driven optimization strategies to revolutionize radiotherapy planning by significantly reducing planning time and enhancing treatment plan quality.

Abstract :

The initial estimate of the critical voltage leading to the initiation of the electric arc carries great economic importance, because it positively affects the technical approach adopted in the analysis of electrical connections. This is especially true in many countries that tend towards a preventive approach by using of a large number of insulators. It has been found that empirical mathematical equations and models somewhat facilitate the estimation of the critical flashover voltage. However, these estimates can vary because of distinct constants associated with each type of insulator. The novelty of the proposed work is the development of new method by hybridization of two artificial intelligent techniques to make easy the estimation of critical flashover voltage value of insulators. The hybrid principle has been chosen, between the Particle swarm optimization (PSO) method, with a similar principle based approach, the Whale optimization Algorithm(WOA). The goal shifted towards employing artificial intelligence to find uniform arc constants that are compatible with all available insulators, and approach the experimental values achieved for each insulator. We randomly select initial values for the arc constants. Using the first method, we reach optimal values for these constants, and then we repeat the process several times to create a database of good solutions. We use this database as initial values for the second method to guide the solution, and we repeat the process each time. Taking into account the objective function on one hand and achieving the closest possible convergence with the experimental values on the other hand, we ultimately obtain two unified values for the arc constants that can be adopted in calculating the critical voltage for each type of insulator. After multiple iterations, we have achieved favorable results. The result obtained proved to be better than what was reached previously, and this confirms that the combination between the theories is a good solution that can be relied upon. The obtained values demonstrate good alignment with the experimental data, indicating their practical importance, especially in the context of technical study and economic considerations.

Abstract :

Attendance monitoring is very important at schools, colleges, offices and many more places. Conventional attendance system takes more time to record attendance and sometimes there is a chance of proxy attendance. Even in biometric attendance system also students need to give thumb impression, which consumes time. To overcome the problems of conventional and biometric attendance systems smart attendance systems came in to picture. This paper proposes a smart contactless attendance recording system for classroom students using face recognition technique. Initially students need to register with name, roll number and set of images and this information will be saved as database. Next an image of each student is captured and image processing is done to extract facial traits, and then compares those features to a database of people who have registered with the system. The attendance is automatically marked in excel sheet if a match is discovered. Face detection and recognition are done with the help of Haar cascade classifier, the Local Binary Pattern Histogram methods and K nearest neighbour algorithms. From simulations it is observed that K nearest neighbours algorithm is more accurate but requires more space and time compared to Haar cascade classifier.

Abstract :

This Project describes a one-sided Schmitt-triggered with data independent read and write operation from a 9T Static Random-Access Memory (SRAM) cell that consume less power and has excellent read and write stability. The existing approaches are performed with data leakage problem, huge area, expensive energy per access read data bits. To solve this problem, the proposed work will introduce three duplications of Static RAM cells with read ports to arise ST 12T SRAM, with the goal of greatly reducing data based read port leakage to improve the read quality and minimize area and power.

Abstract :

With the advancement of technology, the size of transistors and the distance between them are reducing rapidly. Therefore, the critical charge of sensitive nodes is reducing, making SRAM cells, used for aerospace applications, more vulnerable to soft-error. If a radiation particle strikes a sensitive node of the standard 6T SRAM cell, the stored data in the cell are flipped, causing a single-event upset (SEU). Therefore, in this project, a Soft-Error-Aware Read-Stability-Enhanced Low Power 12T (SARP12T) SRAM cell is proposed to mitigate SEUs. To analyze the relative performance of SARP12T, it is compared with other recently published soft-error-aware SRAM cells, QUCCE12T, 10T SRAM12T, RHD12T, RHPD12T and RSP14T. All the sensitive nodes of SARP12T can regain their data even if the node values are flipped due to a radiation strike. Furthermore, SARP12T can recover from the effect of single event multi-node upsets (SEMNUs) induced at its storage node pair. Along with these advantages, the proposed cell exhibits the highest read stability, as the ‘0’-storing storage node, which is directly accessed by the bit line during read operation, can recover from any upset. Furthermore, SARP12T consumes the least hold power. SARP12T also exhibits higher write ability and shorter write delay than most of the comparison cells. All these improvements in the proposed cell are obtained by exhibiting only a slightly longer read delay and consuming slightly higher read and write energy.

Abstract :

History and Objectives: The thyroid gland, which is one of the major endocrine organs in the human body, plays a crucial role in regulating daily metabolism. Death rates from thyroid disorders are decreased by early identification. Radiologists and pathologists typically diagnose thyroid illness, and this process strongly relies on their training and knowledge. This study reveals that deep learning-powered algorithms successfully identify thyroid problems automatically, supporting doctors' diagnostic choices and lowering the incidence of human false-positive diagnoses. The present study is a pioneering effort in the field, as it is the first of its kind to employ two preoperative medical imaging modalities for the purpose of multi-classifying thyroid disease categories. The mentioned elements encompass adenoma, a benign condition characterized by the presence of cystic structures and many nodules, as well as thyroiditis, a condition involving inflammation of the thyroid gland. Additionally, the term "normal" is included. This paper presents a diagnostic model for thyroid disease utilizing a cutting-edge deep convolutional neural network (CNN) architecture. The model aims to distinguish between different types of thyroid illnesses. The findings of the study are as follows: The model demonstrates high performance in both categories of medical images, achieving accuracy scores of 0.972 for computed tomography (CT) scans and 0.942 for ultrasound images. The experimental findings underscore the appropriateness of the chosen convolutional neural network (CNN) for both visual modalities, hence emphasizing the potential clinical uses of the deep learning model

Abstract :

The identification of eye disorders using fundus images poses a substantial challenge to the medical field. In fact, distinct phases of severity are shown by each pathology, and these stages may be deduced by confirming presence of lesions and defining their morphological characteristics. Moreover, several lesions with distinct diseases share traits with one another. Several techniques have been put out for using fundus images to identify eye conditions. Because deep learning (DL) based techniques may tailor the network to the desired detection outcome, they outperform other methods in terms of detection. This paper identifies ocular diseases using DL based techniques. Adaptive Wiener filter is first used to resize, crop, reflect, and eliminate noise from the image. Subsequently, SMOTE is used to address data imbalances and perform data augmentations. Lastly, a method for illness identification called Federated Deep Learning (FDL) is suggested. We used FDL to four pre-trained models, including convolutional neural network (CNN), VGG16, VGG19, and ResNetV2. DL models taught centrally are contrasted with those learnt within the federated framework.

Abstract :

Lightning is a major disruptive phenomenon in the operation of all electrical installations. Lightning has always been a cause of disruption in the use of electricity. However, it is important to note the fairly recent and growing requirement for the quality of electrical systems (reliability, availability, continuity of service, etc.) as well as the constant concern to minimize the costs of using and producing electricity. This leads us to see that lightning becomes a hard point in improving all these factors. In this article, we present the ATP software that we will use in the simulation. After that, we discussed the description of lightning strikes and how to protect facilities from them. The next important step, which represents the novelty of this work, was to create a lightning strike model using the MATLAB/SIMULINK program, based on the mathematical equation of a lightning strike. After that, by using the model created, we simulated a lightning strike that attacked two different nodes of an electrical network, generators, and nine nodes, using the two simulation software's ATP/EMTP and MATLAB/SIMULINK to study the effect of the lightning strike on the voltages and currents of our network system. At the end of the work, we compared the results obtained by the two simulation software, ATP/EMTP and MATLAB/SIMULINK, and we discussed and explained the results obtained by the two software.

Abstract :

Since Hans Berger's 1920s introduction of EEG, its signals have been vital for diagnosing neurological issues and other applications. Brain-computer interfaces (BCIs) have transformed mind-controlled robotics, with Deep Learning enhancing EEG signal decoding. However, factors like substance abuse and Parkinson's disease pose classification challenges. To address these complexities, our research designed and validated a dual-model architecture. The aim was to generalize motor imagery classification for mind-controlled robots, encompassing both healthy individuals and those affected by substance addiction. This extended to assessing the real-world applications of these models in piloting advanced robotic platforms, including quad-rotors and wheeled mobile robots. Our empirical evaluation highlighted clear distinctions between the SVM and attention-based Bi-LSTM models; With the SVM, precision values fluctuated within a range of 0.702 to 0.782, while recall metrics varied between 0.705 and 0.790. On the other hand, the attention-based Bi-LSTM model demonstrated a broader precision range of 0.744 to 0.864 and recall values spanning from 0.752 to 0.856. Impressively, the average precision and recall for the Bi-LSTM model stood at 0.807 and 0.809 respectively, indicating its robust and consistent performance. Additionally, the presented confusion matrix further substantiates the heightened efficiency of the attention-based Bi-LSTM model in EEG signal classification. The evident proficiency of this model in classifying EEG signals ushers in an innovative and inclusive approach to mind-controlled tasks. This not only advances the BCI field but also signals promising avenues for therapeutic and rehabilitative measures tailored for those with neurological discrepancies.

Abstract :

Concrete is a porous material, and the pores are crucial for its strength and durability. In this way, low porosity is the best way to protect concrete against the most aggressive attacks. This study aims to investigate the effect of different additives on the concrete's capillary absorption and breakdown in harsh environments (hydrochloric acid (HCl) and sulfuric acid (H2SO4)) after 30, 90, and 180 days of being completely submerged. To find out how long sand concrete (SC) can stand up to chemical attack, three different mixtures were tested: 10SF5BFS (10% silica fume and 5% blast furnace slag, replaced by the weight of cement), 10SF (10% silica fume), 5BFS (5% blast furnace slag), and SC0 (no substitution as control). These mixtures were selected to investigate the effect of mineral additives SF and BFS on the chemical behavior of SC in a harsh environment. Moreover, the capillary absorption and mass variation of SC were studied. According to the durability results, replacing the cement with 10% SF reduced the capillary absorption by 40%. After 180 days of storage in HCl and H2SO4 acids, 10SF5BFS and 10SF types of concrete offer perfect resistance to chemical attack compared to other concretes.

Abstract :

This project discusses a comprehensive control of a wind turbine system linked to a pid-enabled industrial plant; an algorithm was developed to enable a control structure that employs a four-leg inverter linked to the grid side; this inverter injects the available energy and acts as an active power filter; this reduces load current disturbances and improves power quality. Nonlinear and linear loads in three-phase and single-phase configurations are addressed in a four-wire system. During the connection of the wind turbine, the utility side controller is designed to adjust the disturbances created in presence of reactive, non-linear and/or unbalanced single- and intra-phase loads, in addition to supplying active and reactive power as required. The controller's DC-link capacitor and grid-connected power converter are designed to enhance power quality when wind power is unavailable. The key difference of the suggested methodology with respect to others in the literature is that the proposed control structure is based on the Conservative Power Theory decompositions. This option gives power and current references for the inverter control that are decoupled, allowing for a wide range of customization, granular control, and robust performance. Software benchmarking in real time has been used to assess how well the suggested control algorithm would do in a production setting. The control strategy is developed in Opal-RT and proven in hardware-in-the-loop (HIL) using a TI DSP. MATLAB/SIMULINK is used to realize the control strategy and verify its accuracy. The findings validated our power quality enhancement control and enabled us to forego the use of passive filters, paving the way for a smaller, more versatile, and more reliable electronic implementation of a control system that is based on a smart grid.

Abstract :

In recent years, the integration of renewable energy sources and their unpredictable nature has posed significant challenges to power grid stability and voltage regulation. To address these issues, the Modular Multilevel Converter (MMC) based Static Synchronous Compensator (Statcom) has emerged as a promising solution for reactive power compensation and voltage improvement. However, one critical concern in MMC-Statcom operation is the voltage balancing of DC capacitors, which directly affects system performance and efficiency. In this research, a novel DC capacitor voltage balancing strategy is proposed for MMC-Statcom to ensure optimal operation and enhanced performance. The proposed strategy employs advanced control algorithms and innovative switching techniques to maintain balanced DC capacitor voltages under varying operating conditions. By achieving balanced capacitor voltages, the MMC-Statcom can effectively compensate reactive power and regulate the grid voltage with improved efficiency and stability. The effectiveness of the proposed DC capacitor voltage balancing strategy is extensively evaluated through simulation studies and experimental validations. Comparative analyses are performed with existing voltage balancing methods, demonstrating superior performance and robustness of the novel strategy. The results showcase its potential for practical implementation in real-world power systems. Overall, this study presents a significant advancement in MMC-Statcom technology, providing an effective solution for reactive power compensation and voltage improvement while ensuring reliable and stable grid operation. The proposed novel DC capacitor voltage balancing strategy holds the promise of contributing to the enhancement of power system stability and facilitating the integration of renewable energy sources in modern electrical grids.

Abstract :

Radar detection and vehicle-to-everything (V2X) communication are two advanced driver assistance system (ADAS) functions used to improve the safety of the road users and their driving experience. However, the proliferation of radars on vehicles and the functionalities expected for V2X because several issues like interference and insufficient communication flow. To address these challenges and optimize the use of the electromagnetic spectrum, the mutualisation of communication and radar detection functions in the same component using millimetre-wave (mm Wave) is proposed. As orthogonal frequency-division multiplexing (OFDM) waveform seems to be the most suitable waveform to enable this cooperation, we propose to investigate the performance of OFDM radar compared to that of current frequency-modulated continuous wave (FMCW) radar. We simulate and analyse the signal-to-noise ratio (SNR) and the probability of detection (PD) of OFDM radar based on the parameters of a current mid-range automotive FMCW corner radar. We observe that FMCW radar has better SNR and PD than OFDM radar under these conditions. However, by applying a coherent integration scheme on receive, the results obtained show that good performance of OFDM radar can be achieved. To check the effect of the parameters used on the communication performance, we provide graphs of the Bit Error Rate (BER). These graphs show that the BER do not suffer from these parameters but rather that they can be beneficial to the communication.

Abstract :

Data aggregation is a process of collecting data in an energy-efficient manner by which the life span of the network is enhanced. Aggregating data is a process of comprising the transmitted packet, in the sense the packet's only necessary information is sent to the remote sink node for further processing. While designing efficient data aggregation algorithms, a few extra requirements have to consider such as energy capabilities of sensor devices, energy resources, and computational capabilities. A novel Statistical Indexed X-means Clustering-based Divergence Butterfly Optimized Recursive Deep Learning Network (SIXC-DBORDLN) is introduced for aggregating the sensed data at the sink node with higher accuracy and minimal time. In SIXC-DBORDLN, Recursive Deep Learning Network comprises five layers, namely one input layer, three hidden layers, and one output layer for performing the data aggregation in WSN. In the SIXC-DBORDLN technique, a number of sensor nodes are considered as input in the input layer. Robin Hood indexive Hannan–Quinn informated X-means clustering algorithm is applied to generate ‘x’ number of clusters based on energy level for the first hidden layer. The residual energy value is calculated for every sensor node in the cluster. Then, assign the sensor nodes to the cluster whose residual energy value is closer to the centroid value. The cluster centroid value gets updated and the process gets repeated until all sensor nodes get reassigned. In hidden layer 2, the cluster head is selected using Jensen- Shannon divergencive butterfly optimization for every cluster based on the residual energy. The sensor node with higher fitness is taken as the cluster head. In hidden layer 3, the cluster head collects the data from all sensor nodes and sent to the sink with minimal delay. In the output layer, the cluster head transmits the data packets to the sink node. In this way, the energy-efficient data aggregation is carried out in WSN. Experimental evaluation is carried out using an agriculture dataset on the factors such as energy consumption, delay, packet delivery ratio, and data aggregation accuracy with respect to a number of sensor nodes.

Abstract :

A wireless sensor network (WSN) consists of spatially distributed independent devices to monitor physical or environmental conditions. Within the communication range of WSN, the sensor nodes transmit the sensed data to the base station. During the data collection, some amount of energy is dissipated. So, an energy-efficient data collection scheme is required for extending the network lifetime. A novel Energy-Aware Best First indexive Weighted Random Decision Forest Classification (EABFIWRDFC) technique is introduced for efficient data collection in WSN with higher accuracy and lesser time consumption. Initially in the ABFIWRDFC technique, a number of sensor nodes and threshold energy levels are initialized for performing the data collection. After that, the energy level of the sensor node is calculated. Camargo's indexive Instant Weighted Random Decision Forest algorithm is introduced to classify the higher energy nodes with majority votes for performing data collection. Random Decision Forest Classifier is an ensemble technique that uses the Camargo's indexive best first decision trees as weak learner to distinguish the higher energy and lesser energy sensor nodes. Then the lesser energy nodes transmit the sensed data packets to the nearest higher energy nodes by using Manhattan distance. After that, the sink node collects the data from the higher energy sensor node with higher accuracy and lesser time consumption. Experimental evaluation is carried out on factors such as energy consumption, packet delivery ratio, packet loss rate, throughput, and delay. The observed simulation results illustrate that the EABFIWRDFC technique efficiently improves the data delivery, throughput and minimizes the energy consumption, loss rate as well as delay than the conventional methods.

Abstract :

This thesis presents a novel cascaded multiport switching reluctance motor (SRM) drive designed for hybrid electric vehicles (HEVs) in this master thesis. The capacity of this technique to adeptly handle energy conversion between the generator/ac grid, battery reserves, and the motor is what makes it special. Aside from that, it provides a strong battery management (BM) system that successfully monitors SOC balance and orchestrates bus voltage regulation. A critical component of our design is the seamless integration of the battery packs and the AHB converter. This not only makes it easier to create cascaded BM modules, but it also prepares the stage for SRM drive-specific multilevel bus voltage and current capacity adjustments. This configuration improves the excitation and demagnetization phases of commutation, broadens the speed spectrum, reduces voltage stresses on switching components, and improves torque capability and overall efficiency. Here tailored the system to meet a variety of operational demands by including alternative driving patterns, regenerative braking systems, and charging techniques into the proposed converter. Our BM strategy's ability to manually link or unlink each battery pack from the power supply is an exciting feature. This one-of-a-kind feature considerably improves the system's fault-tolerance and easily avoids any overcharging or over draining problems during motor activity. Empirical experiments using a three-phase 12/8 SRM confirmed the feasibility and efficacy of our proposed cascaded multiport SRM drive.

Abstract :

The purpose of this work is to enhance the performance of solar panels by allowing them to better follow the sun's path. Currently, solar panels are being used to a far greater degree than ever before. Since this project's goal is to increase the usefulness of solar panels, we've opted to construct it. The four light- dependent resistors in the tracker actively follow the sun's path, and the panel's position is adjusted with the assistance of servo motors to ensure maximum power generation. Simulation and implementation of the most effective algorithm for the dual axis (vertical and horizontal) solar tracker are the main goals of this project. To maximise power production, this simulation rotates the panel across 180 degrees to maximise solar irradiation absorption. Compared to their stationary counterparts, trackers produce more energy because of their greater exposure to the sun's beams. In terms of land efficiency, solar trackers are superior than fixed-tilt systems since they produce more power while taking up about the same amount of area. An improved solar panel efficiency is the goal of this project.

Abstract :

The typical pairing of a DC/DC boost converter and a DC/AC converter is being suggested to be replaced with a hybrid boost converter (HBC), which attempts to decrease switching phases and switching losses. Designing and testing the control system for a three-phase HBC installed in a PV charging station is the main goal of this study. The three-phase AC grid, the DC system supporting hybrid electric vehicles (HPEVs), and the PV system are all interfaced via the HBC. The control strategy is especially made to track the PV system's maximum power point (MPPT), regulate the voltage on the DC bus, and control the AC voltage or reactive power as needed. Detailed switching of power electronics during a test with the control architecture’s, for simulation, MATLAB/SimPowersystems is produced. The simulation results clearly demonstrate that the proposed control technique is practicable. To demonstrate the HBC's control performance, laboratory experiments are also run. The study makes use of a number of indicator terminology, including plug-in hybrid vehicle (PHEV), charging station, maximum power point tracking (MPPT), grid-connected photovoltaic (PV), three-phase hybrid boost converter, and vector control.

Abstract :

An MPPT-based hybrid solar-wind energy conversion system, as well as wind-based renewable energy production, is discussed in this paper. With the help of solar panels and wind turbines, the system will be able to produce an abundance of energy. In order to electrify rural areas, power industries, and do other tasks, this project aims to build a system that employs wind and solar electricity. Energy from the wind and the sun are examples of non-renewable resources. In addition to analyze the performance of the renewable energy system, the maximum power point tracking (MPPT) controller is used to trace the maximum outlet in both wind and solar energy conversion systems. Due to their extensive availability and relative ease of use, solar and wind power production have quickly become the most popular renewable energy sources. No amount of photovoltaic or wind power will be sufficient to meet all of our needs. This leads to the optimization of electrical phenomena and wind systems in order to meet load demand. A standalone hybrid renewable energy system using photovoltaic and wind energy conversion using a perturb and observe technique is suggested in this paper. In order to meet a variety of load scenarios, this system's application combines the benefits of all generating technologies and provides watts.

Abstract :

In this research, we show how a Distributed Incremental Adaptive Filter (DIAF) may be used to efficiently manage a utility-interfaced Photovoltaic (PV) - battery microgrid for high power quality. The grid needs to be turned on in case of a blackout. However, the PV-battery system is intended to keep serving critical loads even if the distribution network goes down. Unpredictable power delivery from PV arrays due to unexpected weather changes can be mitigated with the use of a bidirectional controlled converter and a battery. The Voltage Source Converter (VSC) receives the most available power and splits it between the main power source and the nonlinear loads. The VSC is controlled by the DIAF and is powered by the PV array and the battery system. When the system is coupled to nonlinear loads, the DIAF-driven control not only provides regulated power distribution, but also reduces harmonics, effectively balances loads, and boosts power factor. A PV Power Feed- Forward (PVFF) component is included to enhance the current regulation. This not only enhances the dynamic operations of a residential PV-battery microgrid, but also allows for the injection of active electricity into the main grid. In addition to enhancing fuel efficiency, the Battery Energy Storage (BES) helps maintain microgrid stability. This study proves that a PV-battery microgrid constructed in a lab can function as intended.

Abstract :

The global community is presently undergoing a pandemic, specifically the COVID-19 pandemic, which has emerged as a consequence of the identification of a novel coronavirus disease in Wuhan, China in 2019. Consequently, a considerable number of over 200 countries and dependent territories have witnessed an approximate total of 768 million infections, leading to a significant loss of 69.5 million lives. As a result, the global economy, daily life, and individuals' health will experience adverse consequences. Hence, the timely detection of COVID-19 is imperative to mitigate its transmission among individuals and reduce the associated fatality rate. The efficiency and timeliness of COVID-19 case detection can be enhanced through the utilization of computer-aided diagnosis (CAD) techniques in medical imaging, particularly in the context of chest X-rays. This is due to the advantageous characteristic of low radiation exposure offered by CAD, as compared to computed tomography (CT) methods. The present study involves the development of an automated diagnostic methodology utilizing a convolutional neural network (CNN) to forecast the presence of COVID-19 based on chest X-ray images. Our contribution is comprised of three key elements: Initially, the X-ray images undergo data pre-processing techniques, such as image resizing, to adequately prepare them for further analysis. Subsequently, a CNN model is utilized to generate predictions using the aforementioned pre-processed images, striking a balance between the intricacy of the model and computational efficiency. Ultimately, the performance of the model is assessed by employing established evaluation metrics and juxtaposing them against state-of-the-art methodologies.

Abstract :

In this article, a solar photovoltaic (PV) array, a battery energy storage (BES), a diesel generator (DG) set, and a grid-based electric vehicle (EV) charging station (CS) is utilized to provide the incessant charging in islanded, grid-connected, and DG set connected modes. The CS is primarily designed to use the solar PV array and a BES to charge the EV battery. However, in case of exhausted storage battery and unavailable solar PV array generation, the CS intelligently takes power from the grid or DG set. However, the power from DG set is drawn in a manner that it always operates at 80%–85% loading to achieve maximum fuel efficiency under all loading conditions. Moreover, in coordination with the storage battery, the CS regulates the generator voltage and frequency without a mechanical speed governor. It also ensures that the power drawn from the grid or the DG set is at unity power factor even at nonlinear loading. Moreover, the point of common coupling voltage is synchronized to the grid/generator voltage to obtain the ceaseless charging. The CS also performs the vehicle to grid active/reactive power transfer, vehicle to home, and vehicle-to-vehicle power transfer for increasing the operational efficiency of the CS. The operation of the CS is experimentally validated using the prototype developed in the laboratory.

Abstract :

Integrating RESs into the distribution system threatens the reliability and security of the existing power grid. The reliability and consistency of the electricity provided by the system are significantly impacted by the unpredictability of renewable energy sources and fluctuations in demand. Microgrid power and energy storage devices are quite space intensive. Using grid connectivity and energy storage technologies like hybrid batteries and supercapacitors, this initiative aims to provide a solid foundation for solar energy management. The integration of a supercapacitor and a battery storage system allows for the rapid handling of both short-term and long-term power fluctuations, resulting in a more stable system and an easier time navigating fluctuations in PV output. How the grid and the battery are typically divided up in terms of average power is revealed by the battery's state of charge (SOC). Also provided is a method for controlling energy that is both practical and beneficial. Another benefit of using a supercapacitor is that it reduces stress on the battery system in the event of a sudden disparity between produced and required power. Simulations validate the efficacy and viability of the proposed energy management strategy.

Abstract :

This study demonstrates a technique for converting wind power into electrical current using a three-phase, multipurpose inverter linked to the electrical grid. The system under study is connected to the electricity grid at the shared connection point. An inverter for three-phase voltage sources, a wind turbine equipped with a permanent magnet synchronous generator, and a rectifier make it up. Using direct power control ensures it can handle multiple tasks. Uses for direct current power conversion (DPC) include increasing dynamic power, decreasing harmonics in line current, and increasing wind energy. The simulation results demonstrate the effectiveness of the proposed strategy. The system's control algorithm eliminates harmonic currents, compensates for reactive power, and transfers active power from the PMSG wind rotor to the load or the grid, according to the outcome. This allowed us to verify that our proposed solution was solid. One way to harness wind power is with a wind energy conversion system, or WECS. You might think of it as a DPC system with a permanent magnet synchronous generator (PMSG), a rectifier, a converter, and a few more components.

Abstract :

Numerical impulse response Wireless sensor networks (WSNs) and signal processing both frequently use FIR filters. The multipliers used in the design of FIR filter topologies are notoriously space-hogs. When putting together complicated algorithms, FIR filter design relies heavily on performance aspects like hardware cost and area. Three different kinds of adders—the Kogge stone adder, the sklansky adder, and the square root carry select adder—were chosen for this task. This paper's objectives include being familiar with the XILINX synthesizer, creating an RTL for the constructions, and confirming the structures' capacity to perform the desired functions. Different types of FIR trees are compared to one another in terms of pace. In this paper, the VERILOG programming language to create a FIR filter in XILINX ISE is being used. VERILOG is used to write the code for the FIR filter in this paper, and waveform simulation is used so that the results may be analyzed.
