Abstract The objective of the study is developing a simple yet informative mathematical model that describes the kinetics of melting a rod under the action of a localized periodically moving heat source. For this purpose, a cell model is used with the heat conduction matrix that takes into account different properties of liquid and solid phases of the rod material. Zones of the rod that are outside of the local heat source action have heat exchange with the outside environment. It is shown that the melting kinetics strongly depends on the program of heat source motion along the rod and on its residence time at each of its positions. The optimal program of heat source motion that allows melting the whole rod over the shortest possible period of time is found. © 2015 Elsevier Masson SAS. Source

This research devoted to the problems arising in the process of male underwear designing. To improve the situation it's necessary to renew and increase all the data bases. 1st data base is about male body, its structure and body sizes, morphology, sensitiveness of soft tissue under compression pressure done by knitted materials, elasticity of soft tissue and ability to reshaping to get push-up effects. 2nd data base is about the knitted textile material, its properties including comfort, elongation, ability to compress and reshape the soft tissue, and way of using the properties mentioned in pattern block design. 3rd data base is about the structure of underwear including the number of details, inner seams configurations to help the body compression. We have found out some significant relations between these parameters from mentioned data bases and establish into the system, which can provide the new algorithm of pattern block making. Source

The results of theoretical research of making new combined sewing technologies on the basis of chemical materials have been presented in the article. Requirements to chemical materials, restrictions and stimulus for formation concentration operations have been determined. The possibility of realization of seams hermetic sealing simultaneously with connection on sewing equipment has been shown. Source

A cell mathematical model of two-dimensional thermal state of a building envelop near an embedded item is proposed. The model is based on the recurrent matrix equality that describes the thermal state evolution taking into account the phase transformation in the wall material. The main operator of the model is the matrix of heat conduction for a complex two-dimensional domain, in which the physical properties have jump variation at the borders of zones that are presented by the shape matrix and take into account the embedded item configuration. An example of calculating the temperature field and calculating the configuration of the freeze-up zone at different positions of the wall-embedded item is presented. © 2015 Elsevier Ltd.

It is suggested procedure for analysis of two first order factors influencing the output (realization) of products, costs and profit: the output in physically term and its structure. The second-order factors which determine the output in physically term and its structure are: the number of working equipment, the average number of days of work in year, hours of work in day and productivity of the machinery. Methodical problems in the analysis of the second-order factors are considered. Source
