Mathematical and Computer Model of the Tree Crown Ignition Process from a Mobile Grassroots Fire
No full textForest fires cause great damage to the environment and are
difficult to predict and eliminate. Mathematical models of temperature
regimes of forest fires can create a scientific basis for improving the
effectiveness of firefighting measures. The study of fire propagation pro cesses and temperature regimes during a fire is an urgent task that many
researchers are engaged in. The processes of heat exchange in the process
of fire are very complex and include many factors. For this reason, they
are difficult to model. The equations of heat transfer processes them selves are also difficult to solve and obtain analytical solutions.The aim
of this work is to create a mathematical model of the ignition of a needle
from the flame of a moving ground fire. The solution of the set tasks was
carried out by the method of direct integration.The model of the process
of heating the lower part of the tree crown due to the moving grass fire
described in this paper has the advantage that it is based on mathemat ical calculations that can be easily performed using the mathematical
software package Maple. The program in the Maple package is offered,
which, depending on the input data: the size of the fire area, the speed
of fire spread, the distance from the ground to the bottom of the crown,
calculates the air temperature. These results can be used to calculate
and assess the operational situation during forest fires
Research on the feasibility of employing gamification technologies in the training process of IT specialization seekers
No full textDespite the significant amount of published work on gamification in education, many aspects remain unexplored. Including question of gamification in gender perspectives and age-related considerations that has not been investigated yet. Amount of evidence-based researches, long-term studies and effective recommendations on gamifying educational content are equal to zero. The aim of this study is to find out the feasibility of introducing gamification technologies into the process of training applicants for IT majors. To achieve this aim, various scientific research methods were used, including literature analysis, experiments, result comparisons, and data analysis techniques. Multiple hypotheses on the effectiveness of gamification technologies in the process of training applicants for IT majors were formulated and investigated. Specifically, the study examined if there’s a significant correlation between participation levels in gamified courses and overall learning effectiveness, if active time spent in gamified courses positively impacts effectiveness, and if task completion relates to learning improvement for each specific task. Visualizations of the obtained results have been conducted. Particularly, a Scatter Plot with Regression Line has been constructed to depict the relationship between the level of participation in the gamified course and overall academic performance. Additionally, a Heat map correlation matrix has been created to display the level of dependence between the number of attempts for each test and the final exam score, along with other graphs. Python library tools in the Jupyter Notebook environment facilitated these analyses. In conclusion, participation in the gamified course positively impacts learning effectiveness, although its strength may vary depending on specific conditions
Algorithm of rescue units logistic support planning in the process of regional life safety systems development
No full textThe problem of resource support planning in the process of reforming and developing rescue units of regional life safety systems is highlighted in this research. The absence of methods that allow optimizing the required amount of rescue equipment of the region in accordance with the optimal safety criterion is emphasized. Formulated the task of optimizing the safety criterion with the parameter of the number of rescue equipment and limitation in the form of logistical support capability. According to the results of previous studies, the algorithm and its software were developed for implementation in relation to planning of logistic support of rescue units (in the context of providing rescue equipment), which allows to determine the index of the optimal number of rescue units. The developed algorithm was tested on the example of administrative-territorial units of Lviv region, which showed its effectiveness
