COVID-19, a disease produced by the SARS-CoV-2 virus, has had and continues to have a major influence on humankind. This pandemic has wreaked havoc on the global economy, pushing governments to take drastic steps to control its spread. Forecasting the growth of COVID-19 can assist healthcare providers, policymakers, manufacturers, and merchants predict the pandemic’s recurrence and the general public to have faith in the decisions made by them. Various existing findings showed that time-series techniques could learn and scale to properly anticipate how many people would be harmed by Covid-19 in the future. In this research, we did a comparative analysis of univariate time series models and multivariate time series models for confirming a better model at the end. As a result, we aim to bring out a time series model that is more suitable for forecasting the progression of pandemics worldwide, thus being a more reliable model. The research results showed that multivariate time series forecasting produced much better results for long-range than univariate time series models, which showed better results when expecting shorter periods.

Sign language is an effective mode of conversation for persons who have difficulty speaking or hearing. There are numerous media accessible for translation or for identifying sign languages and converting those to text format, However, methods for converting text to sign language have been few and even not web-based software, owing to the scarcity of resources. The proposed web application seeks to develop a translating mechanism or automation that includes a parser element that converts the incoming speech data or English text to a phrase structure grammar representation, which is then used by another module that contains Indi Sign language grammatical format. This is accomplished through the means of removing stop-words from the reordered input format. Because Indian sign language does not provide word inflections, stemming and lemmatization are used to turn words into their root form. Following sentence filtration, all words are tested against the words in the database, which is represented as a dictionary comprising video representations of each word. If the words are missing from the database, the algorithm will then look for its related synonym and replace it with that term.In many ways, the proposed system is more innovative and efficient than existing systems, because Existing methods can only convert words directly into Indi sign language, and they were not as efficient as this system, whereas this in the actual world, the system tries to translate these phrases into Indian sign language grammatical order. Because this is a web-based programmed, it is straightforward to access and use. This technology is platform agnostic and more versatile to use, and it transforms phrases to sign language in real time.

In recent years, Distributed Generation (DG) has created a great impact on the development of small-scale generation and green energy production. To meet the up-surging energy demand, renewable energy sources (RES) has integrated with the grid which helps in increasing generation capacity. The integration with the grid merely may not solve all the problems at all times. However, it will be effective only when the losses are minimized, uninterrupted and a reliable supply of power is present. On the other hand, Power quality (PQ) issues like harmonic distortion, voltage fluctuations, voltage flickering, power transients, etc., rise during integration. Monitoring and mitigating these power quality problems while integrating RES with the grid is the scope of research. This paper presents a comprehensive review of various power quality issues associated with the integration of DG units and their mitigation methods using different algorithms, control techniques, and devices.

Kinovea is a low-cost 2D motion analysis software. The main objective of this study is to examine the performance of Kinovea to compute spatial parameters related to perturbation training as it is not yet studied, allowing a less computational cost analysis of reactive stepping made possible. Thirty-eight healthy young adults performed the Lean and release perturbation technique to produce spatial parameters such as the Step length (SL), Step width (SW), and Leg angle (LA). The Intra-class Correlation Coefficient (ICC(3,1)) quantified the intra- and inter-rater reliability. The Standard Error of Measurement (SEM), SEM% and Minimal Detectable Change (MDC95) for the 95% confidence interval is estimated to find the absolute reliability. The Bland-Altman plot of intra-rater reliability is computed to find the limit of agreement. The results suggest that the Kinovea software is a reliable tool that can produce original values with acceptable error while repeating the analysis. Kinovea software’s excellent ICC(3,1) value, absolute reliability, and low MDC95 value suggests that the software may be a valuable tool to analyze and provide a reliable output related to perturbation training.

The Coronavirus disease 2019 (COVID-19) is a highly infectious disease caused by the severe acute respiratory syndrome. The disease was first instigated in December 2019 in the place called Wuhan which is the capital of a province in China named Hubei and meanwhile, it has spread universally throughout the world. The impact is greatly influenced so that World Health Organization (WHO) has declared the ongoing pandemic of COVID-19 a Public Health Emergency. Artificial intelligence renders its support to analyze chest X-ray (CXR) images for COVID-19 diagnosis. This proposed system is aimed to automatically detect COVID-19 patients using digital chest x- ray images while increasing the accuracy of the model tried with different convolution layers. The dataset was created as a mixture of publicly available X-ray images from patients with confirmed COVID-19 disease and healthy folks. To alleviate the small number of samples, we have inculcated many data augmentation techniques that further enhance the accuracy of the model with different convolution layers. The research aims to design a Deep Learning based model for Covid 19 prediction through X-Ray images. The parameters chosen are applied over 3 different models designed by varying Convolution Layers and proved that accuracy enhances when number of layers increases.

Vehicular Adhoc Networks (VANET) is the fundamental unit for intelligent transportation systems (ITS) controlling and real-time monitoring the Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communication. Due to wireless communication channels, vehicles and Roadside Units (RSU) are susceptible to various network attacks, especially security and privacy. Many existing schemes focused on message authentication but did not respond quickly, hence inefficient. There is a great demand to develop an efficient and anonymous authentication protocol to ensure secure communication between different vehicles without revealing their identities. To address these issues, this article presents a lightweight anonymous authentication key agreement scheme between vehicles and RSUs using smart cards and biometrics only. In addition, authentication involves only two entities, at a time, without involving the Registration Centre. The proposed scheme bypasses costly operations like bilinear pairing and multiplication on an elliptic curve instead uses lightweight operations hash function and exclusive-OR operations to ensure the scheme is computationally efficient. Along with all the known attacks, the proposed scheme attains forward secrecy, detects unauthorized login quickly, and revokes smart cards.

Extra-terrestrial space exploration projects have been a matter of interest with many space agencies given the possibility of non – Earth life forms, life-nurturing environments, or the presence of valuable minerals within our solar system. The present study conducts an aerodynamic analysis on a submarine body capable of examining the extra-terrestrial seas of Titan, which is expected to harbor life forms using CFD. Computational Fluid Dynamics or CFD is used to analyze the aerodynamic properties of the submarine. The present case is set up by enabling the liquid properties like that of Titan's seas with submarine deeply submerged inside the lake moving at a velocity of 1 – 3 m/s. The average drag coefficient observed for the L/D ratios 10.8, 12.5, and 14.4 is 0.059, 0.067, and 0.072, respectively, for the assumed geometry when the submarine is submerged deep inside the seas.

Power electronic converters are essential in the conditioning of electrical energy in a wide range of applications. To enhance the reliability of these power converters, different condition monitoring approaches are adapted that can analyze the health condition of power converters in real-time. The Intelligent Health Surveillance and IoT fault diagnosis system has recently gained attention due to its readiness and operational flexibility. This article proposes an intelligent fault diagnostic algorithm for an IoT-integrated three-phase two-level voltage converter. The proposed fault diagnosis scheme detects single and double open circuit switch faults using simple Park’s vector-based technique. The normalized mean value and the absolute average value of phase currents are used as fault indicators in the proposed scheme. Obtained real-time fault data is further processed in cloud platforms for long-term storage and analysis. An application is developed for the acquisition and visualization of fault data, as well as to receive an alert message in their registered e-mail account.
