Using the DeLone and McLean (D&M) Model, the study explains the differences between female and male students’ accessibility to E-learning portals. This study compares female and male student groups regarding the usage of the E-learning portal in the higher education context. Using an online google survey, the data were collected from 254 students, including males and females. The study utilized PLS-SEM to perform a multi-group analysis examining female and male student groups. The multi-g...

‘Covid cases, deaths being underreported’ May 30, 2021 Deaths during the second wave could be around 7 lakh, scientists estimate Underreporting of cases and mortality were more acute in India during the second wave of Covid-19 pandemic compared to the first wave, and close to 7 lakh people died during the current surge till May 15 compared to nearly 1.16 lakh deaths reported, according to a mathematical model proposed by a team of researchers from Union of Michigan and the Indian Statisti...

Abstract Soft actuators are versatile and can readily perform various functions and interact safely with humans and the environment owing to their deformability. Shape memory alloys (SMAs) have advantages of high power-to-weight ratio, silent operation, and high response speed, which make them suitable for fabricating soft, compact, and muscle-like soft actuators with various transformation capabilities. However, it is challenging to precisely control SMA-based soft actuators and robots because...

Abstract The mixed driving of human-driven and automated vehicles is believed to be the most likely future transportation pattern, and this work studies longitudinal-lateral state estimation for human-driven preceding target vehicles (PTVs) in such situations, as this information cannot be directly obtained by the host vehicle (HV). For longitudinal state estimation, the constant turn rate and acceleration (CTRA) model is adopted and the unscented Kalman filter (UKF) is used for estimator const...

Abstract Multiple vehicles control at an intersection is one of the most challenging scenarios in the vehicle control field due to the high number of constraints. However, regarding the control strategies of an isolated intersection, few studies have considered the longitudinal-lateral dynamics comprehensively. In the approaches that treat the turning curve as a straight line, a longitudinal dynamic model is adopted, while the lateral execution ability is ignored. The ideal decisions that ignor...

Washington [US], May 8 (ANI): In a new paper, a team of environmental engineers presented their results: a model that predicts where the disease will spread from an outbreak, in what patterns and how quickly.

Deep learning has gained much traction in application to state-of-charge (SOC) estimation for Li-ion batteries in electric vehicle applications. However, with the vast selection of architectures and hyperparameter combinations, it remains challenging to design an accurate and robust SOC estimation model with a sufficiently low computation cost. Therefore, this study provides a comparative evaluation among commonly used deep learning models from the recurrent, convolutional and feedforward archit...

Representative image. NEW DELHI: The current increase in Covid-19 infections may not lead to a second wave experienced by some nations as a mathematical model predicts cases ranging between 300,000 to 500,000 in the next 10 weeks. The model sees most cases in the first three weeks of March. It estimates over 57% of the population in India has already been exposed to Covid-19 virus. Though the scientists, working on this model, are waiting for confirmed data on recoveries, their preliminary f...
