The development of personal mobile microprocessor gadgets, computer mathematics systems and interactive online supplements allow victoriousness in the initial process by algorithms of symbolic mathematics, numerical methods and hard functional graphical. The article shows a choice of options for engineering development of a standard task of assigning a normal depth in line with a trapezoidal living process.
Discernible shortcomings of symbolic and numerical algorithms in the development of tasks in the CAS MAXIMA system. The article presents a visualization and method of a simple iterative solution of tasks. An assessment of the accuracy of the result was carried out using the graphical method. In parallel, the solution of the tasks is taken from the Web-interface to the on-line service of the CAS MAXIMA system on the CESGA server.
ORCID : 0000-0003-4878-6850, Київський національний університет будівництва і архітектури ПРО ПІДВИЩЕННЯ ТОЧНОСТІ РОЗРАХУНКУ НЕПРЯМОГО ГІРАВЛІЧНОГО УДАРУ У СИСТЕМАХ МІСЬКОГО ВОДОПОСТАЧАННЯ Розглядаються особливості впливу зміни опору засувки під час її закриття на зменшення швидкості в трубопроводі при непрямому гідравлічному ударі. Вперше показано, що підвищення тиску змінюється з часом не за лінійним, а більш складним степеневим законом. Наводяться конкретні рекомендації щодо визначення підвищення тиску або часу закриття засувки. Ключові слова: гідравлічний удар, зміна опору засувки за час її закриття, підвищення тиску, фаза удару, залежність опору засувки від часу її закриття.
Research and calculations of non-uniform motion are very important from a practical point of view and have certain features for different states of flow, analysis of the shape of free surface curves, as well as the design of many hydraulic structures. When considering these issues, the concepts of specific cross-sectional energy and critical depth are used.
The current trend of technology development in the educational process is based on Internet communications, instant online calculations and mobile microprocessor gadgets with appropriate software. The presented experimental project of educational and methodical material with web forms of online calculation of individual tasks is a variant of the modern competitive online environment on the Internet.
Further direction of development - addition of methodical video, audio and graphic elements. Analysis of web analytics will gradually simplify the interface and choose the most effective set of modern formats for teaching materials.
Computer on-line calculations allow to change the initial data and to introduce elements of modeling and in-depth study of theoretical positions using one typical example in the form of a web form
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
