Sharp-Interface Limit of a Fluctuating Phase-Field Model

We present a derivation of the sharp-interface limit of a generic fluctuating phase-field model for solidification. As a main result, we obtain a sharp-interface projection which presents noise terms in both the diffusion equation and in the moving boundary conditions. The presented procedure does not rely on the fluctuation-dissipation theorem, and can therefore be applied to account for both internal and external fluctuations in either variational or non-variational phase-field formulations. In particular, it can be used to introduce thermodynamical fluctuations in non-variational formulations of the phase-field model, which permit to reach better computational efficiency and provide more flexibility for describing some features of specific physical situations. This opens the possibility of performing quantitative phase-field simulations in crystal growth while accounting for the proper fluctuations of the system.Comment: 21 pages, 1 figure, submitted to Phys.

Temperature Measurement in a THM Solution Zone for the Growth of Hg1-xCdxTe

A combined process for temperature measurements in THM growth systems is described including the preparation of the source material as well as the liquid solution zone in one and the same ampoule. Using starting compositions with an excess of that component to act as the solvent the solution zone is formed during the travelling heater procedure. With thermocouples attached to the slightly modified ampoule axial temperature distributions were recorded under the usual THM growth conditions. The measurements were done in Hg0.8Cd0.2Te growing from Te-rich solution zones. The procedure described can be applied to all materials for which THM crystal growth can be achieved

Evaluation of quality level in managing the development of industrial enterprises

The research focuses on the substantiation of theoretical aspects and practical support for assessing the quality level of managing enterprises development taking into account the influence of the external and internal environment. The conceptual apparatus for estimation of quality development of enterprise management was refined, which makes it possible to determine reasonably the level of management according to the generally known elements (economic, social and ecological) that are proposed to be supplemented with an energy component. A new conceptual approach to the procedure of evaluation of the quality of development management by levels, the stages of which are proposed to expand by: the formation of the database by levels of management (state, regional), choice and evaluation of indicators by components of development and spheres of activity, development of the tools for management improvement. The integrated indicator has been proposed, which differs from the existing ones by the fact that it estimates the quality of development management, rather than the development level. In contrast to the previously proposed ones, the integrated indicator takes into account the influence of external environment by the components of development and of the internal environment – by the areas of activity for each component. That is why it has practical significance, since it allows performing monitoring and detecting the negative influence of management on the enterprise development. Taking coke plants as an example, the structures of the indicators that characterize the management quality were determined. A large number of indicators were reduced by the method of expert assessments, which increases the validity of the choice. Indicator estimates were constructed solely based on relative indicators (indices), which improves consistency. Using the integrated method, the estimation of the indicators by individual components and on the whole was performed. The scale for evaluation of the quality level of enterprise development management was constructed using the Harrington function. The new approach to assessing the quality of the enterprise development management and a complex of mathematical support will lead to the uniform economic, social, environmental and energy development of enterprises.Роботу присвячено обґрунтуванню теоретичних аспектiв та практичного забезпечення оцiнки якiсного рiвня управлiння розвитком пiдприємств з урахуванням впливу зовнiшнього та внутрiшнього середовища. Уточнено понятiйний апарат щодо оцiнки якiсного розвитку управлiння пiдприємствами, який дозволяє обґрунтовано визначати рiвень управлiння за загальновiдомими складовими (економiчної, соцiальної та екологiчної), до яких запропоновано додати енергетичну складову. Побудовано новий концептуальний пiдхiд до процедури оцiнки якостi управлiння розвитком за рiвнями, етапи якої запропоновано розширити за: формуванням бази даних за рiвнями управлiння (державний, регiональний), вибiр та оцiнка iндикаторiв за складовими розвитку та сферами дiяльностi, розробка iнструментiв щодо покращення управлiння. Запропоновано iнтегральний показника, який вiдрiзняється вiд iснуючих тим, що оцiнює якiсть управлiння розвитком, а не рiвень розвитку. На вiдмiну вiд запропонованих ранiше iнтегральний показник враховує вплив зовнiшнього середовища за складовими розвитку та внутрiшнього – за сферами дiяльностi по кожнiй складовiй. Тому, має практичну значимiсть, оскiльки стає можливим проводити монiторинг та виявляти негативний вплив управлiння на розвиток пiдприємства. На прикладi коксохiмiчних пiдприємств визначено склад iндикаторiв, якi характеризують якiсть управлiння. Велику кiлькiсть iндикаторiв скорочено за допомогою методу експертних оцiнок, що пiдвищує обґрунтованiсть вибору. Iндикаторнi оцiнки побудовано виключно за вiдносними показниками (iндексами), що покращує узгодженiсть. За iнтегральним методом проведена оцiнка iндикаторiв за окремими складовими та у цiлому. За функцiєю Харрiнгтону побудовано шкалу оцiнки якiсного рiвня управлiння розвитком пiдприємств. Новий пiдхiд щодо оцiнки якостi управлiння розвитком пiдприємств та комплекс математичного забезпечення приведе до рiвномiрного економiчного, соцiального, екологiчного i енергетичного розвитку пiдприємств

Creation of the image and brand of the enterprise on the basis of marketing as a philosophy of management

The modern development of an enterprise is possible only on the basis of marketing since the enterprise is effective only in case of its usefulness for consumers, the relation with which is one of the main marketing functions, i.e., marketing is a philosophy of management. The purpose of the paper is to study the theoretical background and practice of interaction of image and brand of an enterprise on the basis of marketing as a philosophy of management. Methodology. Approbation of the results is presented on the example of business projects for 2017 and 2018 of enterprises with different business scales in Kharkiv and Kharkiv region of Ukraine: small – the Centre for Child Development “Cute Kids”, medium – Association of Confectionery Enterprises “Solodkyi Svit” (“Sweet World”), large – Turboatom JSC, by means of research methods: theoretical generalization, system approach, expert estimation method. Results. The work results are the development of methodological approach to evaluating the effectiveness of the marketing department in the process of business management at the enterprise, taking into account the enterprise value and brand value for large industrial enterprises, the peculiarity of which is the ability to investigate the relationship between the effectiveness of the development of the marketing department (organizational and managerial aspect) and the performance of its divisions (economic aspect) and take into account the identified causal relationships in the process of enterprise activity. The system for evaluating the performance of the marketing department, taking into account enterprise value and brand value, involves two levels of assessment: the first one allows determining its performance in general, that is, the effectiveness of its development, the second one takes into account the specifics of divisions of this department of the enterprise and allows determining their performance according to individual results, that is, the effectiveness of divisions, which is reflected in the basic social and economic performance indicators of the enterprise. The effectiveness of the development of the marketing department is evaluated using the following indicators: development trend ratio, marketing efficiency ratio, management process productivity ratio, division productivity ratio, and executive efficiency ratio. The calculation is based on individual indicators: an integral indicator of the effectiveness of the development of the marketing department, which is calculated by the normalized part of the indicators for additive convolution, taking into account their ratios of significance, and by performance indicators of marketing research division (sales volume, market share, building market strength), the work of the business development division is evaluated using indicators (“corporate image”, “enterprise competitiveness”, “profit”, “consumer readiness”, “partner’s business attractiveness”), communication division (trade turnover, information base update, development of partner relations, brand value), which are interrelated, interdependent, reveal the essence of determining the performance of the marketing department at different angles, allow justifying the adjustment of certain aspects of marketing development at the enterprise, and are calculated as arithmetic mean values of performance indicators of the divisions. Conclusions. Practical approbation of the proposed approach is presented on the example of large industrial enterprise named Turboatom JSC and confirms the practical value of the worked out approach to evaluating the performance of the marketing department in the process of managing the activities of an industrial enterprise, taking into account enterprise value and brand value

Social networks of older people in contemporary society

Modern society is a field of information exchange and communication. Therefore, people assume that it is easier nowadays for individuals to maintain their social networks. Internet technologies, mobile phones all we use on a daily basis to keep in touch with our loved ones. However, the situation looks different when we think about elderly people. It is not that easy for them to introduce technology in their lives. That is why the question stays open: is it easy for older people to stay in touch with their families and friends in contemporary world? In this article, we explore the social network of elderly people. We reveal how the opportunities for older people to lead an active social life have been changing throughout past century. The article explores the phenomena of the deliberate social network shrink, which happens when people retire, or starting to have health issues connected with ageing. Article also reveals new opportunities for extending social network of an elder person with non-kin participants
