  • Optimizing the performance of Triple Input DC-DC converter in an
           Integrated System

    • Authors: Chirag Gupta; Vikas Kumar Aharwal
      Abstract: Power electronic converters are absolutely necessary for the notion of a hybrid energy system to integrate hybrid energy sources (HES). In this paper, a triple input DC-DC converter with buck-boost operating ability is presented. Multiple energy sources with various I-V characteristics can be integrated using the converter. Using the voltage-second concept, the output equation of the converter is determined from various operational conditions. The MATLAB / SIMULINK software was used to develop and simulate this converter topology. For the purpose of assessing the performance of the converter three different input sources with various voltage levels of 40 V, 30 V, and 16 V are used. Additionally, the adeptness profile of the proposed converter under different loading conditions has been examined, and this analysis demonstrates clearly that the converter under discussion has a high level of efficiency.

  • Evaluation of Z-Source Inverter Topologies for Power Conditioning Unit for
           DC Power Supply Systems

    • Authors: Pravin Ratanlal Choube; Vikas Kumar Aharwal
      Abstract: In order to operate a wind turbine generator, careful and extensive research is required as different environmental conditions result in different wind speeds. Standard type of induction generators and compatible electric generators are great in the construction of low-speed applications. Due to the improved architecture and lower PM material emissions, a permanent magnet generator is an ideal choice for low-speed direct applications. Different topologies of permanent magnet generator are available, such as radial flux, axial flux, and transverse flux PMG. The sophisticated structure of the permanent axial flux generator is not suitable for use in large wind turbines. Due to the simple structure of radial flux PMG, the formation of multiple poles can be easily incorporated into the nascalle of wind turbines. To overcome these obstacles, this research project proposes a new topology quasi-Z-source Matrix converter-based DC / DC using a zigzag transformer, and simulation is performed and compared with other existing DC-based Z-source converters. DC will be approved at the beginning of the power supply unit in DC power supply systems.

  • Single Point Incremental Forming (SPIF) of Aluminum Alloy AA 1050:
           Experimental evaluation of the effect of process parameters on surface

    • Authors: Dharmanshu Singh Sodha; Keshav Dutt
      Abstract: The work on single point incremental forming of Aluminium alloy (AA1050) was done experimentally. The impact of process variables including tool shape, tool size, step size, and feed was examined on surface roughness. Research was conducted utilizing the Response Surface Methodology (RSM). The relevance of process parameters was determined using analysis of variance (ANOVA). The tool's form was found to have the biggest impact on surface roughness. The surface roughness is also greatly influenced by the tool size and step size. Higher feed rates can be used without degrading surface quality since feed has the least impact on surface roughness.

  • Comparative assessment of anti-anemic effect of Sucrosomial iron in
           haloperidol-induced iron deficiency anemia in Wistar rats

    • Authors: Manoj A. Suva; Pravin R. Tirgar
      Abstract: Anemia affects almost one-third of the world's population. Conventional oral iron salts have limitations such as poor bioavailability and poor tolerability. Sucrosomial iron gets absorbed through the hepcidin independent pathway; hence overcoming all these limitations. The present study assessed the anti-anemic effect of various iron salts on hematological parameters in haloperidol-induced iron deficiency anemia in Wistar rats. Iron deficiency anemia was induced by haloperidol injection (2.5 mg/kg body weight/day i.m.) for initial 5 days along with an iron-deficient diet throughout the study. Disease control animals received ferrous sulfate, ferrous ascorbate, ferrous fumarate, and Sucrosomial iron at a dose of 30 mg/kg p.o for 15 days. On day 20, animals treated with all iron-supplemented groups showed significant improvement in hematological parameters. Interestingly, the Sucrosomial iron group showed significantly higher improvement in hemoglobin levels and hematocrit parameters than other oral iron salt groups (P<0.05). This effect may be due to the higher bioavailability of Sucrosomial iron. We concluded that Sucrosomial iron exhibited a potent anti-anemic effect against haloperidol-induced iron deficiency anemia in Wistar rats compared to other conventional oral iron salts.

  • Design of 5G Microstrip patch array antenna for gain enhancement

    • Authors: Mahesh K. Pote; Prachi Mukherji, Aditi Sonawane
      Abstract: A Novel 5G antenna is designed in this research, which resonates at 28GHz. In modern wireless communication, there is a need to develop a 5G antenna with enhanced gain value, and the antenna size should be small and low-profile. The design of the patch of the 5G antenna consists of a rectangular ring of 8mmx5mm. The rectangular ring is of 1mm size from all sides. Various antenna parameters are measured, such as S-parameter [1,1], gain, radiation pattern, and bandwidth. The return loss of the antenna obtained is -24.79dB. The average gain obtained in the proposed 5G antenna is 7.9 dBi, and the radiation pattern of the antenna is Unidirectional, bandwidth range is 27.36-29.29GHz, with centre frequency 28.108GHz, and four-element array antennas are with merits of average gain of 13.385dBi, bandwidth ranges from 27.29-29.14GHz, centre frequency 28.024GHz. A 5G array antenna of the size 1x4 is designed, which greatly increases the antenna's gain. A Defective ground structure (DGS) is implemented on the ground plane to improve the antenna performance. The DGS is implemented on the ground plane by introducing three Concentric circles, and the antenna's bandwidth is improved using the Concentric circles. The array antenna enhances some antenna characteristics. An edge feeding strategy is used to feed the antenna, and the ANSYS HFSS programme simulates the proposed antenna.

  • Multiband frequency switchable Microstrip antenna design for satellite

    • Authors: Keshav Dutt; Dharmanshu Singh Sodha
      Abstract: This article illustrates a novel PIN diode-based small microstrip multiband reconfigurable antenna design. Three frequencies, 4.85GHz, 10.04GHz, and 15.09GHz, are resonant with the proposed design. These bands cover the roughly equivalent C band (4-8GHz), X band (8-12GHz), and Ku band (12-18GHz) microwave frequency bands. The PIN diodes are then added to this antenna to enable reconfigurability. A novel reconfigurability technique is put forth to address the difficulties associated with multiband operation. In close proximity to the microstrip line, the three pin diodes are sorted to ground with parasitic for each of the three bands. The parasitic element is connected to a particular PIN diode microstrip line that, when turned ON, for single frequency band. The scattering parameters loss plots analyzed with far field radiation pattern along with smith chart.

    • Authors: Sachin Sharma; Priyanka Pandey, Rakesh Bhandari, Abhay M Shende
      Abstract: Nowadays, Demolition construction waste is in very high demand in the market and is also useful to improve the higher strength of designed ecofriendly concrete compared to Conventional Concrete. Natural sand and fine aggregate supplies are diminishing in the market as a result of large major building and the desire to minimize the cost of concrete production by using demolition construction waste as a substitute of fine aggregates in the modified green concrete. The utilization of demolition construction wastes as fine aggregate in concrete would also be beneficial in economic impact and also maintain the environment. The durability and mechanical properties of modified concrete are improved. Various Grade of mix design of concrete as per (IS 10262:2009) can give better results with demolition construction waste as replacement of fine aggregates at age of 28 days curing periods. From the various literature review, here various results obtained it is suggested that demolition construction waste with a replacement level of up to 20% can be used as a fine aggregate for improvement of modified concrete.

  • Discrete Hartley Transform and its applications - A review

    • Authors: Nibedita Patra; Sudhansu Sekhar Nayak
      Abstract: Digital signal processing (DSP) has become the single most powerful essential component in all technological applications, which include multimedia as well as mobile communications, data compression, network cameras, mobile phones, sensor imaging, acoustic beam formers, GPS, but also biomedical signal processing, and so on. Almost all of these applications place various demands on DSP systems, such as the ability to handle high throughput data as required by real-world applications, the requirement for reduced power, and the need for chip space. Transforms are helpful to convert one data type to another in DSP applications. The Hartley Transform (DHT) is important in Digital Signal Processing. When the input sequence is real, DHT is equivalent to Fast Fourier transform and it is utilized in the applications of image and optical signal processing, computer vision as well as teleconferencing and processing or analysis of moving images. Many DHT algorithms are developed by the authors for the application of optical signal processing, image processing as well as VLSI implementations and the review has been presented in this paper.

  • Development of suitable closed loop system for effective wind power

    • Authors: Pravin Ratanlal Choube; Vikas Kumar Aharwal
      Abstract: The use of wind energy, a significant renewable energy source, has been expanding quickly in recent decades on a global scale. Higher standards for the power output and dependability of generators and converters are necessary due to the rising capacity of both onshore and offshore wind power generation. Multiphase wind power generation systems have clear advantages over traditional three-phase wind power generation systems in low-voltage, high-power operation, improved fault-tolerant, and increased degrees of control freedom, which help them gain more and more traction in the field of contemporary wind power generation. This paper provides an overview of the multiphase energy conversion of wind power generation and introduces relevant technological advancements, such as the multiphase converter topologies, modelling, and control of multiphase generators. This paper will provide an overview of DC-AC and AC-AC ZSCs, as well as the case for their application as wind power converters in a variety of topologies. This work suggests a novel direct torque control space vector modulation (DTC-SVM) based closed loop speed control of an induction motor supplied by a high-performance Z-source inverter (ZSI).

  • The robust and efficient Machine learning model for smart farming
           decisions and allied intelligent agriculture decisions

    • Authors: Shraban Kumar Apat; Jyotirmaya Mishra, K. Srujan Raju, Neelamadhab Padhy
      Abstract: Crop Yield Prediction is essential in today's rapidly changing agricultural market (CYP). Accurate prediction relies on machine learning algorithms and selected features. Any machine learning algorithm's performance might well be enhanced by introducing a diverse set of features into the same training dataset. Crop yield prediction includes parameters such as temperature, humidity, pH, rainfall, as well as crop name in forecasting the yield of the crop based on historical data. It offers us an indication of the best crop to expect in terms of weather conditions in the field. Crop prediction is a difficult task in the agricultural realm. The primary purpose of this research is to offer a novel machine learning approach for a heterogeneous data environment containing IoT-sensed data about the environment, agricultural conditions, plants' features, demands, etc. We have used data set of the following five crops (rice, ragi, gram, potato & onion) collected from Andhra Pradesh, Kaggle repository. In this work, we utilized diverse machine learning as well as deep learning algorithms such as Regression methods, Decision tree, Naive Bayes, SVM, K-Means, Expectation-Maximization (EM), and AI techniques (LSTM, RNN). It seems that among machine learning techniques, the Random Forest algorithm outperforms with 99.27% training accuracy for crop yield prediction. However, among sigmoid, ReLu, and tanh activation, sigmoid achieves 99.71 percent accuracy with four hidden layers for predicting the crop yield prediction.

  • Niosomal formulation of Quercetin and Resveratrol and in-vitro release

    • Authors: Nivetha Murugesan; Chandraprabha Damodaran, Selvakumar Krishnamoorthy
      Abstract: Dietary polyphenols from plant origins play a major role in the human diet. They supply efficient antioxidants that reduce or prevent ROS production depending on the concentration. However, these polyphenols are less bio-available in the body due to various parameters, including low intrinsic activity, poor absorption, high metabolism, inactivity of metabolic products, and/or rapid elimination. Quercetin and resveratrol are dietary polyphenols that are often found in the human diet. However, they lag in bioavailability, which makes them less preferred nutraceuticals. This particular study is aimed at increasing the bioavailability of quercetin and resveratrol through the nano vector system, niosomes. In this study, niosomes entrapped with Quercetin and Resveratrol were produced in different concentrations of Span 60 and cholesterol using the thin film hydration method. The best suitable composition, which provides maximum entrapment, was taken for further study. The niosomal formulation of quercetin and resveratrol was evaluated using various methods like solubility and shape. The entrapment efficiency was determined to be 61.55%. The niosomes were then characterized using a zeta sizer and a potential. The average particle size of niosomes was 194 diameter values in nanometers, and their zeta potential was -20 mV, which indicated their good stability. The results of the in vitro drug release research, which was conducted using phosphate buffer saline pH 7.4, were that 92.6% in 24 hours was significantly increased compared to quercetin and resveratrol release, 71.30%. The ex vivo drug release was 94.5% after 24 hours, which was higher when compared to quercetin and resveratrol release of 75.74%. The results of this study indicate that the niosomes significantly enhanced the bioavailability of quercetin and resveratrol.

           medical data in healthcare

    • Authors: Renuka R. Patil; A. Usha Ruby, Chaithanya B N, Swasthika Jain T J, Geetha K
      Abstract: Artificial Intelligence (AI) can identify substantial interactions by considering the datasets in the emerging era of technologies. It is widely applied in various applications, and healthcare is among them. AI plays a vital role in clinical applications in predicting the disease type, treating the disease, managing chronic situations, and diagnosing the same. AI in the healthcare environment has simplified the lives of doctors, patients, and administrators at hospitals by operating various tasks with lesser computation time and accurate results. The unique challenges such as availability, accessibility, and affordability of AI have contributed to healthcare applications' success. Another factor that enhances the functionality of AI is based on the sourced medical data, which is analyzed, and a model is built to predict the disease by the application of Machine Learning (ML). The other reason for the successful application of AI in the healthcare environment is Computational Intelligence (CI), which is an analysis, design, theory, and development of linguistically and biologically motivated computational techniques. The functionality of CI is identified on the three pillars such as Fuzzy Systems, Neural Networks, and Evolutionary Computation.

  • Review of reliability indices of the water distribution system

    • Authors: Suja S. Nair; T R Neelakantan
      Abstract: Over the last few years, there has been a growing emphasis on reliability in water dissemination networks. The water supply network's dependability is crucial in today's water delivery system. The capacity of a water distribution network to fulfil requirements with significant pressure under normal and abnormal situations is referred to as system reliability. The development of a system for analyzing and enhancing the reliability of water delivery systems is underway. Enhanced options are offered to increase network dependability, and then an optimization study is used to choose the best upgrade option based on a predetermined goal function. Reliability does not rely on certain criteria. In today's world, computer-aided programs impact the simulation model and the water supply network study. This analysis shows the factors that can be utilized to determine dependability.

  • Automated hybrid Deep Neural Network model for fake news identification
           and classification in social networks

    • Authors: Roshan R. Karwa; Sunil R. Gupta
      Abstract: The rapid growth of social media has far-reaching impacts on civilization, traditions, and economics, including both beneficial and unfavourable implications. Since social networking sites have become more frequently utilized for transmitting data, they have also become a gateway for the distribution of fake news for diverse financial and legislative goals. Artificial Intelligence (AI) and Natural Language Processing (NLP) approaches have a lot of ability for academics who wish to design models that can recognize fake news automatically. On the other hand, identifying fake news is a difficult issue because it demands systems that describe the news and then contrast it to the actual news to categorize it as fake. Thus, to overcome this, this paper introduces Hybrid Deep Neural Network Model, in which C-DSSM and Deep CNN models have been utilized. It identifies and classifies fake news using the LIAR dataset. According to experimental results, the proposed model obtained an accuracy of 92.60%, a recall of 92.40%, a precision of 92.50%, and an F1 score of 92.50%. Furthermore, the proposed model is compared to earlier studies for fake news identification using the LIAR dataset, and the proposed model's performance is remarkable. As a result, the proposed hybrid model gives better results in detecting and classifying fake news on social networks.

  • Optimized energy-efficient multi-hop routing algorithm for better coverage
           in mobile wireless sensor networks

    • Authors: K. Phani Rama Krishna; Ramakrishna Thirumuru
      Abstract: The Mobile Wireless Sensor Network (MWSN) comprises transceivers that collect information and transfer it to the access point through other hubs. Both mobile networks and access points can be portable and work apace with stable devices in the network, depending on the application requirements. Numerous studies have been undertaken to develop sensor nodes considering energy and mobility, with LEACH-based routing algorithms providing the best results. However, the Low Energy Adaptive Clustering Hierarchy-based energy-efficient navigation system best suits small-scale systems. Whenever the connection is huge, long-distance transmission between cluster members and the Base Station (BS) consumes much energy. Thus to overcome it, this research grants an innovative scheduling algorithm that adapts to sensor node transmission to deliver dependable and energy-efficient navigation named Optimized Energy Efficient Routing Algorithm for Better Coverage in Wireless Sensor Networks. Firstly, our research paper presents a unique method called Low Energy Adaptive Tier Clustering Hierarchy (LEATCH), which achieves a reasonable balance of latency and energy usage while addressing various covering concerns in MWSN. Moreover, a novel Honey Bee Algorithm is utilized to find the potential and hyper-cluster heads. As a result, based on power, latency, coverage, stability period, and scalability, the optimized LEATCH protocol outperforms other energy-efficient clustering protocols.

    • Authors: Sunita Kumari Yadav; Priya Bhardwaj, Praveen Gupta, Daman Saluja, Sunita Jetly, Jyoti Taneja
      Abstract: Due to a lack of data on various parameters with COVID-19 in the Indian population, this study was carried out to understand the relation among gender, age and comorbidities in Indian population. The data was collected using a questionnaire-based survey form that included questions on demographic characteristics, infection and any pre-underlying conditions (n=1146). The data showed that the male patients had suffered more from COVID-19 (58.6%). Also, the patients suffering from comorbidity are more likely to suffer from a severe form of COVID-19 and obesity/overweight was identified as the most prevalent (n=69) comorbid condition, followed by diabetes (n=35), thyroid (n=19) and hypertension (n=11). In severe COVID-19 cases, 85% of patients had a comorbid condition. In another study of COVID-19 hospitalized-cases, about 97% of patients were found to have an underlying medical condition. Among these, diabetes (55.9%) was identified as the most prevalent comorbidity. Males and older people are at a higher risk of developing COVID-19 infection in Indian population. The comorbid conditions also predisposed individuals to COVID-19 and aggravated the infection.

  • Novel electrospun nanofibers incorporated with flavonoid glycosides from
           Glinus oppositifolius (L.) Aug. DC. for antibacterial dressings

    • Authors: K. Suresh Kannan; D. Kandavel, S. Balamurugan, P. Rajalakshmi, K Selvakumar
      Abstract: Electrospun nanofibers are non-woven fibers with diameters in nano size, produced from natural or synthetic materials or a combination of both using electrospinning apparatus. These nanofibers find usage in different fields, especially in medical research and the healthcare sector for their varied properties. Apart from the core polymers which are essential for nanofiber formation, several other bioactive ingredients are complexed in nanofiber production to add value to the end product. In this current research work, flavonoid glycosides from the medicinal plant Glinus oppositifolius were extracted, purified using column and high-performance liquid chromatographic methods and tested for their antibacterial efficiency. The bioactive compounds were then blended in the nanofiber formulation to produce nanofiber-based anti-bacterial dressings through the electrospinning technique. The nanofibers were tested through FTIR for analyzing the composition of the final product and further subjected to scanning electron microscopical analysis to study morphology and nano size. The nanofibers thus produced exhibited strong anti-bacterial activity against tested pathogens namely K. pneumonia, P. vulgaris and Streptococcus sp. The positive results showed that further research can be carried out to optimize the production and medical dressing applications of the nanofiber.

  • An effective feature descriptor method to classify plant leaf diseases
           using eXtreme Gradient Boost

    • Authors: A Usha Ruby; Chaithanya B N, Swasthika Jain T J, Smita Darandale, Sudarshana Kerenalli, Renuka Patil
      Abstract: Identifying plant leaf diseases will be highly difficult due to the difficulties in gathering lesion characteristics from a quickly changing atmosphere, imbalanced illumination reflection of the incoming light source, and numerous other factors. A practical strategy for classifying plant leaf diseases is provided in this research. Using HSV, HU moments, and color histograms, we first created a leaf feature improvement framework that can enhance leaf characteristics in a complicated environment. Then, to increase feature classification capacity, a competent extreme boost method is modelled. Batch normalization is used to avoid network overfitting while also improving the model's resilience. The plant leaf disease feature improvement approach is favorable to boosting the efficiency of the XGBoost classification, as demonstrated in studies from various perspectives. For plant leaf disease photos obtained in the natural environment, our technique displays significant resilience, serving as a benchmark for the intelligent categorization of additional plant leaf diseases.

  • Review of computational approaches to model transcranial direct current
           stimulations tDCS and its effectiveness

    • Authors: Utkarsh Vinodchandra Pancholi; Vijay Dave
      Abstract: Neurological and psychological disorders are being treated by health professionals using medical technologies including drug therapy, electrical stimulation, and psychotherapy in some cases. Because of side effects caused by required drugs and social stigma for psychotherapy, these techniques have some limitations for their applicability in Mild cognitive impairment (MCI), Alzheimer’s disease (AD), Huntington disease (HD), dementia, major depressive disorder (MDD) and related neurological abnormalities.  Transcranial direct current stimulation is a non-invasive brain stimulation (NIBS) technique that uses small currents to alter characteristics of a healthy and diseased neuron. Even though sophisticated tDCS devices are being used for treatment, treatment protocol and its efficacy is still a debatable question. Researchers have found ways to model tDCS computationally to know the outcome of treatment. This review provides details of computational approaches used to model tDCS. We have reviewed clinical and computational practices carried out by researchers to model treatment modality for tDCS.

  • The COVID-19 havoc and clues from Sex disaggregated data in the Indian

    • Authors: Divya Bajaj; Varunendra Singh Rawat, Kanika Malik, Neetu Kukreja Wadhwa
      Abstract: The coronavirus infectious disease (COVID-19) has created a turmoil across the globe, with India emerging as one of the worst-hit countries. The Global scenario indicates a gender bias with a higher COVID-19 Case fatality rate (CFR) in males as opposed to females. However, countries like India, Nepal, Vietnam and Slovenia have reported a reverse trend in mortality. Real-time disaggregated data empowers countries to design more effective, sustainable, and people-centered approaches to treat and prevent COVID-19. Our study aimed to procure sex-disaggregated data in the Indian population by using a google form based online health survey. We have analyzed parameters like age, gender, occupation, sex and severity of infection based on CT score, steroid dependence, need for hospitalization, etc. The responses were evaluated by descriptive statistics by excluding arbitrary correlation. We found that the males were at a significantly greater risk of severe disease and mortality (~ twice) than females. We also found that the males as compared to females, presented almost eighteen times the odds of requiring intensive care unit (ICU) admission; reflecting severity of the infection. A sex-informed approach to COVID-19 research would reveal novel responses of the host immune system to SARS-CoV-2, which can then be utilized in formulation of policies for equitable health outcomes.

  • Association of ABO blood group and antibody class with susceptibility and
           severity of COVID-19 infection in Indian Population

    • Authors: Jyoti Taneja; Priya Bhardwaj, Sunita K Yadav, Daman Saluja
      Abstract: Since the COVID-19 eruption in December 2019, the investigation has been focused on its treatment and preventing the disease spread. Currently, there is no biomarker available that can predict the predisposition and severity of COVID-19 infection. In the present study, we have used the cross-sectional survey study data to decipher the association between the ABO blood group and susceptibility, severity and breakthrough COVID-19 infections. Further, we have also investigated the association between antibody class and the risk of contracting COVID-19 infection. Our results indicated that individuals with blood group B had higher susceptibility to acquire COVID-19 infection. In contrast, blood group A was found to be associated with a low risk of acquiring severe COVID-19. In addition, we did not find any correlation between ABO blood groups and breakthrough COVID-19 infections. Further, we examined the association of antibodies; anti-A (blood groups B and O) and anti-B (blood groups A and O) with COVID-19 infection. The analysis of antibody classes showed that anti-A antibody associated with a high predisposition to acquire COVID-19 infection. The present study indicates that blood group B and anti-A antibodies are associated with proneness to COVID -19 infection and severity.

  • Context aware human activity prediction in videos using Hand-Centric
           features and Dynamic programming based prediction algorithm

    • Authors: S.N. Kakarwal; Ashwini Subhash Gavali
      Abstract: Activity prediction in videos deals with predicting human activity before it is fully observed. This work presents a context-aware activity prediction approach that can predict long-duration complex human activities from partially observed video. Here, we consider human poses and interacting objects as a context for activity prediction. The major challenges of context-aware activity predictions are to consider different interacting objects and to differentiate visually similar activity classes, such as cutting a tomato and cutting an apple. This article explores the use of hand-centric features for predicting human activity, consisting of various human-object interactions. A Dynamic Programming Based Activity Prediction Algorithm (DPAPA) is proposed for finding the future activity label based on observed actions. The proposed DPAPA algorithm do not employ Markovian dependencies or Hierarchical representation of activities, and hence is well suited for predicting human activities which are often Non-Markovian and Non-hierarchical. We evaluate results on MPPI Cooking activity dataset which consist of complex and long-duration activities.
