A Systematic Literature Review on Visualisation Skills for Understanding Science

Previous and recent research have documented the argument fuelled by credential scholars about visualisation skills in various subjects. However, whether this visualisation skill can fulfil students’ understanding has been debated. Meanwhile, despite its widely used in other subjects, the application of science subjects, particularly for understanding certain topics, is still sparse. This study identifies suitable visualisation skills to be incorporated into a science learning approach. Furthermore, a systematic literature review has been conducted to achieve the objective. This paper shows the rigorous systematic literature review process done on some selected journal articles and papers on visualisation skills. The analysis indicates that, while different subjects apply different visualisation skills, most share similar themes in implementing visualisation skills as proven necessity advocated in the 21st learning. Thus, these finding act as an enhancing tool to propose the development of various topic visualisation approaches.

Physics informed neural network based scheme and its error analysis for ψ-Caputo type fractional differential equations

This paper proposes a scientific machine learning approach based on Deep Physics Informed Neural Network (PINN) to solve ψ-Caputo-type differential equations. The trial solution is constructed based on the Theory of Functional Connection (TFC), and the loss function is built using the L1-based difference and quadrature rule. The learning is handled using the new hybrid average subtraction, standard deviation-based optimizer, and the nonlinear least squares approach. The training error is theoretically obtained, and the generalization error is derived in terms of training error. Numerical experiments are performed to validate the proposed approach. We also validate our scheme on the SIR model.

Ta`līm al-Qawā`id an-Naḥwiyyah Bi aṭ-Ṭarīqah al-Istiqrāiyyah `Alā Asās al-Madkhal al-`Ilmī Bi Ma`had al-Muhājirīn Aceh Besar

Arabic has two grammars, nahwu, and sharaf. Nahwu specializes in the rule of changing word endings, while Sharaf focuses on word changes. The use of nahwu helps with determining each function of every word in a sentence, the adjustment of word endings, and their positions. Therefore, nahwu is fundamental in learning Arabic. When learning activities took place in the female class VII- A at Junior High School Al-Muhajirin, the initial process was conducive. The teacher taught students by applying the istiqraiyah method. However, the situation in the classroom changed after 30 minutes, especially for students sitting in the back. Some of them ate snacks, talked to each other, and fluttered using books although the room’s temperature was normal. The circumstance happened because the learning activity was teacher-centered, the teacher was more active than the students. The aim of this study was to apply the Istiqraiyah method based on the scientific approach in learning nahwu, to find out students' responses to the application of the method, and to know the influences of the istiqraiyah method based on the scientific approach in the grammar learning in each cycle. The researcher applied the classroom action research (PTK). The population of this study was 172 students. The study sample was female students in class IX-a. There were 36 students. The researcher carried out observations, and tests, and provided questionnaires. The findings of this study were: 1) The implementation of the istiqraiyah method based on the scientific approach was very effective. The teacher observation result in the second circle (94,21%) was higher than the first circle (89,47%). The student observation result in the second circle (93,75%) was higher than the first circle (88, 75%). 2) The students’ responses to the istiqraiyah method based on the scientific approach in learning the nahwu grammatical structure at Dayah Al-Muhajirin were very good. The result of the students' responses in the second circle (86, 11%) was higher than the first one (79,73%). 3) The influences of the istiqraiyah method based on the scientific approach in the nahwu grammar learning at Dayah Al-Muhajirin were effective in improving students' nahwu grammatical skills. The result of the student test in the first cycle (70, 31%) was higher than the test in the pre-cycle (46, 25%). The result of the student test in the second cycle (84,37%) was higher than the student test in the first cycle (70,31%).

Physics-informed neural networks for spherical indentation problems

A scientific deep learning (SciDL) approach was developed by integrating a regression-based spherical indentation method with an artificial neural network (ANN) to extract elastic–plastic properties from indentation load-depth curves. Different combinations of material parameters are constructed through Latin Hypercube Sampling (LHS) process to create a database of indentation parameters. An attempt is made to reversely obtain load-depth (P-h) data using a regression function for a given set of material parameters; this method is further verified by performing finite element (FE) simulations. SciDL models i.e., physics-informed artificial neural network (PI-ANN) with autoencoder (AE) are built based on PyTorch library, and the models are trained using the generated database. Transfer learning (TL) techniques are employed to achieve better training performance with the PI-ANN model. Compared with data-driven models, SciDL models produce consistent predictions with higher accuracy; the coefficient of determination R2 values are observed greater than 0.960. TL techniques allows the SciDL model to learn much faster (≈ 42 epochs) than traditional method (≈ 2400 epochs). Finally, we perform spherical indentation experiments on STS304 and SM45C, and validate the performance of the trained SciDL models; AE integrated PI-ANN model with tanh activation function predicts the material properties close to reference values of SS400 and SM45C. The proposed SciDL approach can be extended for characterizing engineering materials and structures by incorporating any priorly developed mechanical testing method with ANN.

State of the Art and Outlook of Data Science and Machine Learning in Organic Chemistry

Abstract: Data Science and Machine Learning approaches have recently expanded to accelerate the discovery of new materials, drugs, synthetic substances and automated compound identification. In the field of Organic Chemistry, Machine Learning and Data Science are commonly used to predict biological and physiochemical properties of molecules and are referred to as quantitative structure–active relationship (QSAR, for biological properties) and quantitative structure– property relationship (QSPR, for nonbiological properties). Data Science and Machine Learning applications are rapidly growing in chemistry and have been successfully applied to the discovery and optimization of molecular properties, optimization of synthesis, automated structure elucidation, and even the design of novel compounds. The main strength of Data Science tools is the ability to find patterns and relationships that even an experienced researcher may not be able to find, and research in chemistry can benefit from. Moreover, this interdisciplinary field is playing a central role in changing the way not only organic chemistry but also how chemistry is done. As cutting-edge ML tools and algorithms such as tensors, natural language processing, and transformers become mature and reliable by chemists. ML will be a routine analysis in a chemistry laboratory like any other technique or equipment.
