Analysis of different factors on the features of thermal destruction of a fuel pin

The presented work studies the influence of various factors that affect the specific features of fuel pins melting. For this purpose, fuel pins with different geometries and energy release are considered. Numerical simulation of melting is carried out using a program module for calculating the destruction of fuel rods. Comparison with theoretical calculations is made. The analysis of the convergence of calculations with respect to the time step value and the number of calculated cells along the radius and height is carried out. As a result of work with the use of numerical methods, the characteristic times of destruction of fuel elements during an accident with a loss of coolant flow rate (an accident of the ULOF type) and the dependence of weight loss on time are obtained under various conditions.

Aberration analysis of AOTF-based stereoscopic spectral imager using optical design software

Stereoscopic spectral imagers using acousto-optic tunable filters (AOTF) provide high-resolution narrow band images acquired from two viewpoints with different polarization in arbitrary spectral intervals, which allows obtaining three-dimensional hyperspectral models of inspected objects for many applications. We discuss modeling of acousto-optic (AO) cell for optical system design and introduce a program module for ray tracing through AO cell compatible with Zemax optical design software. A detailed study of the optical aberrations that limit the image quality in two AOTF-based stereoscopic systems implementing simultaneous AO diffraction of two differently polarized beams in single AO cell is presented. This approach may be used to design various AOTF-based imaging systems, but the limitations of ray tracing analysis should be considered.

PRINCIPLES FOR DEVELOPMENT OF PROGRAM INTERFACES IN INDUSTRIAL INFORMATION, MEASURING, AND CONTROLLING SYSTEMS

Industrial information, measuring, and controlling systems have a program module designed to convert measurement results into data for display and control signals. A program module interconnected to other modules by program interfaces. In this case, data transformations are necessary when they are sent between modules. Object-oriented design patterns can be used when programming data transformations. When converting measurement results to objects, the Adapter design pattern can be applied. Programming the Command pattern is intended for converting objects into control signals. Data processing should be separated from their representation, storage and transmission. Functions between modules can be divided using the Model–View–Controller pattern. The use of design patterns reduces the development time and subsequent modification of software for both information, measuring, and control systems, as well as systems in other subjects of science and economics.

Developing a parenting program for young couples

In support of developing a parenting program for young couples, this study conducted to determine whether and how significantly the module was affects parenting practice among young couples in a small groups. Data were collected through experimental research. The subjects of this research were young couples with requirements as follows: have children whose age is maximum five years old, graduated from high schools, able to communicate fluently, and are willing to attend all interventions and are not joining any similar training. The subjects were 26 parents who are domiciled in the Province of the Special Region of Yogyakarta, Indonesia and recruited through social media. The data analysis technique was a paired sample t-test. The result indicated -6.299 value t and value p=0.000 or (p0.01). It showed a significant development of parenting comprehension before and after training (mean pretest is about 62.13 and mean post-test is about 78.26). This parenting program module needs to be tested in the wider population to form into final results.

Evaluation tools of current certification: control issues revealing theoretical training of a resident in the specialty «Medical and social expertise and medical and social rehabilitation»

For certification of students for compliance with the requirements of the professional educational program, funds of evaluation funds are created, which allow to evaluate knowledge, skills and mastered competencies. In addition, they should become an effective means of training and mastering the work program (module). The goal of the WCF is, first of all, to create conditions for the development of competencies among students for successful professional implementation. Control questions developed to identify the theoretical training of students allow you to evaluate basic knowledge, logic and other communication skills.

Building of a space form of the flexible inextensible one-layer conic shell

The paper covers the visualization of a volume-space form of the flexible inextensible one-layer shell that is represented in the stress and strain state appearing during fastening the shell on the upper edge and its free location below the fastening border in the field of gravitational and elastic forces of the material. With no account taken of the gravitational forces, the shell is a right circular flattened cone. A developed program module can be used in designing and calculating the thin-wall shell structures during their non-linear deformation and their visualization. Visualization of the space form of the shell structure can be used for simulating various products, for instance, the cone antennae or the textile products, flexible elastic shells in the hydraulic engineering, etc.

An accurate and novel numerical simulation with convergence analysis for nonlinear partial differential equations of Burgers–Fisher type arising in applied sciences

In this study, the second-order nonlinear partial differential equations of Burgers–Fisher type are considered under a unique formulation by introducing a novel highly accurate numerical method based on the Nörlund rational polynomial and matrix-collocation computational system. The method aims to obtain a sustainable approach since it contains the rational structure of the Nörlund polynomial. A unique computer program module, which involves very few routines, is constructed to discuss the precision and efficiency of the method and these few steps are described via an algorithm. A residual function is employed in both the error and convergence analyses with mean value theorem for double integrals. The considered equations in the numerical tests stand for model phenomena arising widely in applied sciences. Graphical and numerical comparisons provide a clear observation about the consistency of the method. All results prove that the method is highly accurate, eligible, and provides the ultimate operation for aforementioned problems.
