Enhancing Students' Preparation for Math Exams using the Advanced Features of the Halomda Platform

This paper highlights the new enhancements of the Halomda platform designed to improve students' learning and exam preparation. The new features include a Graph Plotter, Algebraic Calculator and Context ChatGPT Recommended Key Guidelines. The use of these features is demonstrated though a working example of solving a double integral, illustrating how students' self-preparation for mathematics exams is supported by interactive context feedback. In addition, the system's ability to check intermediate steps of a solution, complemented by graphing, comparison of algebraic equivalence of algebraic operations, and guided AI bot assistance, contributes to an enriched learning experience and improved self-assessment for students. In case of insufficient understanding of the solution, the AI chat can be consulted for further clarification. Since the solution in the "Help" mode is developed by the teacher who prepared the test paper, in case of misunderstanding, the student can turn to external sources, and the fastest way is the AI chat.

EATURES IN THE STUDY OF HANDWRITTEN NOTES AND SIGNATURES MADE WITH PRELIMINARY TECHNICAL PREPARATION USING MODERN TECHNICAL MEANS WITH COMPUTER SUPPORT

The article deals with the features of the study of handwritten notes and signatures made with preliminary technical preparation using modern technical means with computer support. The authors analyzed the establishment of the fact of the technical method of reproducing handwritten notes and signatures with the help of a plotter (graph plotter), which is made by a writing device, but is not handwritten. Based on expert practice, the authors concluded that in order to equip experts with methodological recommendations for establishing the fact of «a technique for reproducing handwritten notes and signatures» using modern technical means with computer support, it is necessary to conduct deeper studies that require significant financial costs, primarily associated with the acquisition of modern plotters (plotters), as well as in the development of new approaches for assessing diagnostic and identification features.

2D Graph Plotter and Visualizer

In many fields of science and engineering, we often encounter the problem of solving N linear equations of type x + y and trigonometric equations. All technological, biological and social networks can be represented as graphs. Therefore, graphs are used in the research of new algorithms and protocols based on simulation in various fields of science. We aim to create a python-based graph generator that will draw any type of equation i.e., linear, algebraic, trigonometric and logarithmic on the graph. More importantly, the application is designed to draw multiple graphs on the same canvas and then analyse the results. We have included one more module where user can upload a CSV file consisting of raw and get a desired pie chart, line graph as well as bar graph. Our system mainly focuses on generating a output for a later analysis by downloading the graphs they have plotted.

FFParam: Standalone package for CHARMM additive and Drude polarizable force field parametrization of small molecules.

Accurate force-field (FF) parameters are key to reliable prediction of properties obtained from molecular modeling (MM) and molecular dynamics (MD) simulations. With ever-widening applicability of MD simulations, robust parameters need to be generated for a wider range of chemical species. The CHARMM General Force Field program (CGenFF, https://cgenff.umaryland.edu/) is a tool for obtaining initial parameters for a given small molecule based on analogy with the available CGenFF parameters. However, improvement of these parameters is often required and performing their optimization remains tedious and time consuming. In addition, tools for optimization of small molecule parameters in the context of the Drude polarizable FF are not yet available. To overcome these issues, the FFParam package has been designed to facilitate the parametrization process. The package includes a graphical user interface (GUI) created using Qt libraries. FFParam supports Gaussian and Psi4 for performing quantum mechanical calculations and CHARMM and OpenMM for MM calculations. A Monte Carlo simulated annealing (MCSA) algorithm has been implemented for automated fitting of partial atomic charge, atomic polarizabilities and Thole scale parameters. The LSFITPAR program is called for automated fitting of bonded parameters. Accordingly, FFParam provides all the features required for generation and analysis of CHARMM and Drude FF parameters for small molecules. FFParam-GUI includes a text editor, graph plotter, molecular visualization, and text to table converter to meet various requirements of the parametrization process. It is anticipated that FFParam will facilitate wider use of CGenFF as well as promote future use of the Drude polarizable FF.

DOTDND: A FORTRAN-77 program for showing graphically the confidence or uncertainty in phylogenetic trees

Abstract Phylogenetic trees are subject to considerable uncertainty because of the sampling error of the set of characters used to construct them. A program is presented to display the confidence as a pattern of dotted lines, dashed lines, thin lines, and thick lines, where least certain branching is shown by the dotted lines and the most reliable regions by the thick lines. The program uses GHOST80 graphics subroutines and a graph plotter.

Improved methods of estimating root length using a photocopier, a light box and a bar code reader

Photocopying was found to be a rapid method of making a permanent record of a root sample. The method used produced a copy with white roots against a black background. Manual estimates of root length were made from photocopies using a light box. The number of intersections visible when laid over a copy of a white on black regular square grid was counted. Automated estimates of root length were made by scanning a photocopy with a bar code reader in place of a pen in a computer-driven graph plotter. Roots >0.2 mm diameter were resolved with precision and speed.

Using a microprocessor to analyse particle shape—a tutorial system

A microprocessor (Apple II) collects images using a single-board TV scanner (Microworks Digisector) connected to an inexpensive security camera or to a scanning electron microscope. Interactive output is obtained from one TV monitor connected to the scanner and another connected to the microcomputer. A graph plotter (Hewlett-Packard 7225A) is used for hard-copy output. The programs are all written in UCSD pascal except for four short assembly language routines used for interfacing the TV scanner. The system is intended for tutorial purposes in computer science courses in addition to its prime application function.

Location-specific information is measured and recorded on site, stored on disc file and the co-ordinate locations extracted, selectively, by interrogation parameters for display on video or line printer terminal, or on the graph plotter. The procedures for data collection, checking and system use are detailed.

Surge tank water level variations following rapid valve opening

An investigation into the movement of the water surface in a surge tank following rapid valve opening is described. At the instant the valve is opened an allowance is made for some flow from the supply pipeline in addition to that from the surge tank and therefore the theory is altered only in the initial conditions. A program was written for a small desk-top calculator linked to a graph plotter to give a visual presentation of the finite difference solutions. Comparison was made with experimental values of the maximum downsurge observed in a model surge tank.

Intelligent digital plotter

Abstract This article describes the use of a microprocessor to control Computer Instrumentation's Series 4/70 flatbed digital graph plotter. It covers both the hardware interface with the plotter and the firmware which controls the actual plotting. It describes how the firmware analyses the various user-controlled functions, and also how it interprets the high-level input language used to describe the plots, and converts these commands into actual pen movement.

Computer programmes for the analysis and presentation of orientation data

This letter gives a brief preliminary description of computer programmes for use by structural geologists. Since the GODPP was described at the Tectonic Studies Group meeting at Dundee in December 1976 a number of workers have expressed interest and this letter is intended to make the existence and scope of the package more widely known. Copies of the programmes involved may be obtained from the authors at University of Bristol. The Geological Orientation Data processing package (GODPP) is a package of computer programmes principally aimed at helping the field geologist to process large quantities of structural and sedimentological orientation data. The programmes have been so written as to be independent of the model of computer used (see Appendix). The package offers the plotting of orientation data on stereograms, maps, and rose diagrams and also offers reorientation routines. Stereograms. This section of the package has facilities for producing Pi diagrams and contoured Beta diagrams with options for a vector mean or a best fit great circle, with the appropriate statistics ( Mardia 1972 ). A large number of programmes to plot stereograms have been published ( Robinson et al. 1963 , Spencer & Clabaugh 1967, Warner 1969 and Bonyun & Stevens 1970). The majority produce line printer output, although a graph plotter has been utilised for the plotting of Pi diagrams ( LaFountain 1970 ), but not apparently for contoured diagrams. GODPP has the advantage of producing Pi diagrams and contoured stereograms on a graph plotter. It also produces line printer output of contoured diagrams which allows

Differential equations, an interdisciplinary model!

A new way of teaching differential equations with interdisciplinary models and a computer is presented. The models are taken from three different fields: physics, chemistry and biology. Students work at the computer in interactive use. They have the choice of the values of different parameters and they can analyse the results on a graphical display unit or a digital graph plotter. Three applications are described in this paper: projectiles, chemical kinetics and interspecific animal competition.

A comparison between experimental and numerical investigations of the motion of the water surface in a model surge tank

This paper describes an investigation into the motion of the water surface in a simple model surge tank, and the relevant factors governing its behaviour. The oscillation of the free water surface is an unsteady flow problem, which is amenable to a mathematical solution using a finite difference step-by-step integration procedure. For comparison, two such methods are presented: (i) a simple initial value method and (ii) a predictor-corrector technique. Computer programs have been developed linked to a graph plotter to give a visual presentation of the numerical solutions together with the experimental results of the damped oscillation of the water surface in the model surge tank.

The Interrelations between Moiré Patterns, Contour Fringes, Optical Surfaces and Their Sum and Difference Effects

A general relationship between potential functions and moire patterns can be realized in a number of forms. The potential function can be worked as an optical surface and combined with other potential functions similarly worked to give the solution to a complex potential problem. Contour fringes can be produced from the optical surfaces or generated on a computer graph plotter directly. When superimposed these contour lines generate moire fringes which are also solutions to potential function problems but with an essential ambiguity of sign. Two circularly symmetrical potential wells have been contoured and moire fringe solutions to simple problems are given.
