 Abstract

The power quality (PQ) of PI-based Grid-Connected Solar Energy Conversation Systems (SECS) when nonlinear loads are coupled to a distribution network is discussed in this paper. When non-linear loads, such as three-phase bridge rectifiers, are connected to a network, harmonics are generated in the network as a result of the switching action. This PQ problems are severe impact on dynamic performance of the SECS, this are solved by employing PI controller based voltage source converters. Satisfactory results are produced using verified simulation results in MATLAB.

 Abstract

One of the intriguing subcategories in the field of image processing is segmentation. As there are so many academics working on image processing segmentation, they are now focusing on Magnetic Resonance Imaging (MRI) segmentations, which is a difficult problem that still requires improvement against noisy data. A popular method for segmenting medical pictures is Fuzzy C Means (FCM), although it only considers the image's intensity and, as a result, yields insufficient results for images with a lot of noise. It is standard practice to design and combine many classifiers using the same fundamental classification learning model using classifiers like bagging and boosting. Boosting models on noiseless data are more robust than bagging. Improving weak learning models significantly reduces errors which only create classifications that are a little better than arbitrary guessing. Results demonstrate the increase in the classification of ac Fuzzy Bee Segmentation method.

When a project calls for the local soil to be improved, adding lime is an appealing option. The purpose of the current study is to develop fundamental guidelines for the use of lime and rock dust in stabilizing soft soils. Lime and combinations of lime and rock dust were used to stabilize the soils (RD). According to the test results, the sub-base layer may be designed with an admixture with an optimal admixture concentration of around 6% lime combined with 25% Rock dust by mass of the soil.

 Abstract

This study suggests that a wind turbine is connected to the grid. It has a solo mode of operation. We may connect the BESS and FC-electrolyze to handle the load required to run the suggested approach in standalone mode. The generator-side converter and the ESS work together to meet the needs of the heaps in this technique where variable speed PMSG serves as the primary power source and BESS and FC-electrolyze serves as a backup. This control strategy may limit the DC-interface voltage of the full-scale power converter to a narrow range while enabling a variety of heap sizes or wind speeds. Using the replica MATLAB/SIMLINK, a reenactment model of a variable speed wind turbine is built in a separate framework. The dynamic exhibition of the independent breeze turbine framework and the proposed control system is evaluated and stressed with the recreation results.

Decentralized wireless networks come in the form of mobile ad hoc networks (MANET). Because it does not rely on pre-existing infrastructure like routers in wired networks or access points in managed (infrastructure) wireless networks, the network is referred to as ad hoc. Instead, each node takes part in routing by sending information to other nodes, therefore the choice of which nodes provide information is decided dynamically based on the connectedness of the network and the routing algorithm being used. Mobile Ad Hoc Networks (MANET) are made up of a number of wireless nodes and function as a dynamic data exchange. Because of node failures, network segmentation, disconnections, and movement, the network topology changes often. Moreover the mobile nodes which are basically resource constrained, exhibit various kinds of faulty behaviors that may be transient or permanent due to the hardware or software problems. In such a situation, the faulty node may not forward packets and the situation becomes worse. Hence fault tolerance is an important design issue to construct a reliable mobile ad hoc network. Due to the presence of faulty nodes, the performance of routing degrades and the reason for the faulty nodes has to be identified to address routing by exploring network redundancies.

 Abstract

Efficiency in energy use plays a critical role in the development of the smart grid in the power system. Hence, a key priority of the intelligent grid is optimal power consumption monitoring and management. One of the main issues with the existing power metre gadget is that there is no full duplex communication. A sophisticated power metre that is entirely based on the Internet of Things is suggested as a solution to this issue (IoT). The suggested smart electricity metre calculates and manages power usage using ESP 8266 12E, a Wi-Fi module, and uploads the results to the cloud where the customer or producer may examine the results. As a result, customer-level energy analysis becomes more easier and more manageable. This gadget additionally helps in detecting electricity theft. Thus, this clever meter helps in domestic automation the usage of IoT and enabling wi-fi conversation which is a terrific step closer to Digital India.

 Abstract

Because to its high fluidity and settling, low self-weight, and low thermal conductivity, foamed concrete is now often utilized in civil construction and building. It does, however, have some significant drawbacks, such as poor strength and increasing shrinking with age. The curing conditions are one of the many factors that affect the strength growth of concrete. By experimenting with different curing techniques, this effort intends to investigate the possible creation of foamed concrete as a sustainable structural material. To do this, sample cubes, cylinders, and prisms were created in order to determine the compressive strength, elastic modulus, and drying shrinkage at various ages. Four different curing regimes were used to cure polyurethane foamed concrete sample pieces (water, moisture, sealing by membrane-forming curing compound and air curing). At the end of the study, poly- urethane foamed concrete used for this study has shown the potential for use in structural applications. Also, the results show that the samples cured by moisture have the highest compressive strength at all ages

 Abstract

Network analysts find it difficult to manually monitor traffic flows and spot breaches in large networks due to the astronomical volume of internet traffic and rising network complexity. Information security is significantly enhanced by intrusion detection systems (IDS). Recently, it has become more common to use Machine Learning (ML) approaches for intrusion-based detection. The network traffic generates a lot of data with irrelevant information, slowing down the detection process and deteriorating system performance. Elimination or selection is carried out prior to categorization to get around that flaw. This research presents a hybrid machine learning-based intrusion detection system that employs recursive feature removal. In order to adequately and effectively analyze network traffic for intrusions, Support Vector Machine (SVM) and Decision Tree (DT) machine learning models are combined into hybrid machine learning model. Furthermore, a multi-class classifier was built to classify not only malicious or benign traffic but also to extend labels upon the malicious data. In order to improve the performance, this system identifies the features which are irrelevant and eliminated it. The feature selection is achieved by using Recursive Feature elimination method. Experiments show improved performance in network intrusion detection.

 Abstract

This study primarily focuses on technique development and validation for the analysis of favipiravir in pharmaceutical dosage forms and pure forms using UV spectroscopy. This procedure calls for the creation of working and standard solutions of the drug favipiravir, followed by the fabrication and analysis of working solution aliquots at various concentrations. Then, the linearity, precision, accuracy, robustness, ruggedness, limit of quantification, and limit of detection of this developed technique were all validated. The information received shows that the procedure was sensitive and accurate within the range of 4-24 g/ml. The correlation coefficient (R2) was found to be 0.999. There is no interference observed with excipients in formulation. The project method may be duly applied for the analysis of Favipiravir in bulk for routine analysis.
