Hydrogenolysis of Glycerol by Heterogeneous Catalysis: A Fractional Order Kinetic Model with Analysis

The demand for glycerol, a by-product of biodiesel manufacturing, is anticipated to surpass supply, necessitating efficient conversion techniques for sustainability. The importance of effective conversion techniques is illustrated by the development of a system of fractional order differential equations using a literature reaction model. This study focuses on understanding and describing potential glycerol hydrogenolysis pathways by investigating the kinetics of a catalyzed hydrogenolysis model using qualitative analysis of fractional order differential equations, as there is limited research on the underlying reactions. The model is analyzed qualitatively and quantitatively using fixed point theorems. It is found to be generalized Ulam-Hyers-Rassias stable. The impact of the fractional operator is studied through computational simulations using a two-step Lagrange polynomial. Graphs at different fractional derivative orders show the significant influence of the fractional order on the model's classes. Even though the results are based on a particular kinetic model, they aim to improve comprehension and description of the process.

How neural networks learn to classify chaotic time series.

We tackle the outstanding issue of analyzing the inner workings of neural networks trained to classify regular-vs-chaotic time series. This setting, well-studied in dynamical systems, enables thorough formal analyses. We focus specifically on a family of networks dubbed large Kernel convolutional neural networks (LKCNNs), recently introduced by Boullé et al. [403, 132261 (2021)]. These non-recursive networks have been shown to outperform other established architectures (e.g., residual networks, shallow neural networks, and fully convolutional networks) at this classification task. Furthermore, they outperform "manual" classification approaches based on direct reconstruction of the Lyapunov exponent. We find that LKCNNs use qualitative properties of the input sequence. We show that LKCNN models trained from random weight initialization, end in two most common performance groups: one with relatively low performance (0.72 average classification accuracy) and one with high classification performance (0.94 average classification accuracy). Notably, the models in the low performance class display periodic activations that are qualitatively similar to those exhibited by LKCNNs with random weights. This could give very general criteria for identifying, a priori, trained weights that yield poor accuracy.

Design and evaluation of a revised ARCS motivational model for online classes in higher education

In recent years, online MOOCs (Massive Open Online Courses) have been quite popular among universities which helps learners to enhance their competency skills apart from learning the regular college/university curriculum. Although distance education and online learning have been adopted gradually recently, it has become the 'New Normal.' In this situation of uncertainty, facilitators must keep themselves updated with the various teaching/learning strategies and encourage learners to get accustomed to the online classroom environment. Furthermore, assisting the learners with active engagement in the classes is essential. Hence, to create an instigated environment for assessing the competency level and addressing the motivational behaviour of the learners in the online courses, a modified version of the "ARCS" (Attention, Relevance, Confidence, and Satisfaction) model is used in this research work. The core objective of this model is to apply a modified motivational model, namely "ARCS-PC," where PC represents Professional Competency. Professional competency includes Critical Thinking skills, Digital literacy, Creative Thinking, Problem-solving, and Time Management. The incorporation of digital quizzes, assignments, and interactive activities using Information and Communication Technology (ICT) tools was done in the ARCS-PC Model. The online classroom lectures and activities were conducted using the Microsoft Teams (MS Teams) educational platform. Linear regression is performed to analyze the modified ARCS-PC model. These technology-enabled online classes and ICT tools have helped teach lifelong learning, collaborative learning, a student-centric approach, and better competency skills to effectively engage students in online courses. In our proposed method, an improvement of 11.21 % was observed in the student's performance compared to a maximum of 8.8 % in the existing traditional models. Detailed analysis and quantification of the proposed method are given in the paper.
