A new geometric algorithm for modeling the contour arc in the form of a curve of one relationship based on the Dezargues configuration, parameterization of which is performed using the mathematical apparatus "Point Calculus", is proposed. The analysis has shown that the obtained contour arc has interesting geometric properties, which can potentially be used for modeling one-dimensional and multidimensional outlines of high order smoothness, which constitutes a prospect for further research. A detailed description of the process of parametrization the contour arc in the point calculus based on the proposed geometric algorithm for its construction with the exception of cumbersome transformations is presented. The given methods of parametrization of geometrical objects in the point calculus on the basis of a simple relation of three points of a straight-line invariant concerning parallel projection, can be used by other researchers for the solution of a wide range of problems of engineering geometry and computer graphics. Examples of modeling spatial and planar, closed and unclosed arcs of the circumference, which can find their application as shape-forming elements of surfaces of technical forms, are given.

The purpose of the article is to determine rational modes for safe and effective ultrasound exposure in order to sanitation urological catheters. It is shown that using an amplitude-modulated or pulsed power supply mode, it is possible to achieve an increase in amplitude, i.e. to improve the quality of cleaning and reduce heat generation. As a result, to technological solutions for the initiation of an ultrasonic emitter have been proposed.

The paper is devoted to planar linear sets generated by linear conditions which are realized for rectangular or Manhattan metrics. The aim of this paper is to give an approach to researching the properties of linear conditions defined on Manhattan plane. Linear conditions are written as a finite sum of products Manhattan distances and real numerical factors. The paper presents a constructive method to solve the next general geometric problem. Let finite sets of linear figures (segments of line, polygons) are given on Manhattan plane at general positions. Find a planar set corresponding to given linear condition based on the given sets. The set of broken lines corresponding to given conditions generates a family of isolines for given sets. Constructive algorithm to build the family is suggested. The algorithm is based on the rectangular Hanan lattice and calculation numerical values in each cell. Some theorems applied to these cases are formulated in the paper.
