GEOMETRY APPLICATION EVOLUTION - FROM RESEARCH TO INDUSTRIAL APPLICATIONS OVER TWO DECADES

Digitalisation is making significant inroads into society at the same time as the general commercial trend is to able to personalise the product one acquires. The field of digital product representation, and the techniques for adopting a particular product in accordance with the customer's expectations, have become very important corporate assets. From a company's perspective these assets can be leveraged both for internal efficiency and also for different types of external customer interactions. In this article, the standpoint is that product geometry forms the foundation for digital product representation. It is from this perspective that the geometrical ecosystem comes into focus. Geometry creation and geometry consumption, in combination with geometrical configuration management, are high-value areas that must be mastered. A research-based 20-year industrial perspective building up such capabilities serves as an example. The article concludes with a forward-looking perspective on potential areas for continued exploration on this journey.

PLANNING FOR OPTIMUM SUPPLY CHAIN THROUGHPUT AS A CRITICAL FACTOR IN MAKING A SUCCESSFUL CHAIN IN THE MARKET

The article discusses the need to ensure the optimal throughput of the supply chain as the most important factor in maintaining the effective and efficient operation of the chain. The notion is given. The importance of throughput planning is noted. It is presented as a search for a compromise between the speed of response to demand and the internal efficiency of the chain links. In addition, some of the barriers that hinder the simplicity of the throughput planning process in the chain are considered. They are the “whip effect” and the conflict of interests of the participants in the chain. The article also proposes approaches that allow to achieve the most efficient planning of throughput in the chain, taking into account all the existing requirements and restrictions. The author proposes supply chain management as a single system and its synchronization with every moment of actual market demand. The next propose is the introduction of strategic alliances.

Internal efficiency of public vocational training centres in Kenya

The efficiency of educational institutions is critical in the justification of resource allocation and use. However, some developing countries like Kenya face efficiency challenges regarding resource utilisation and the flow of students through the school system at various levels of education and programs. Past research in Kenya has focused more on resource utilisation in public schools. Very few studies have looked at the internal efficiency of public vocational training centres (VTCs). This paper assesses the level of internal efficiency in Kenya's public vocational training institutions through a mixed research design. The findings reveal low levels of internal efficiency as indicated by low enrolment, high dropout and low completion rates in the VTC institutions. The result also shows a low level of tutor utilisation. These results provide vital insights into improving the internal efficiency of public vocational training institutions in developing countries. The study recommends, among other things, subsidisation of examination fees to enhance students' completion rates.

Excitonic Harvestation Radiative Recombination by Analysis and Comparison of the Experimental Data Measurements and the Theoretical Data Calculations from Silvaco-TCAD

Organic Light Emitting Diodes (OLEDs) have developed to show many advantageous and noticeable properties including their flexibility, easy processing, very cost effective chemical technology, and easy combining of organic material, hence having optimized performance is very significant. Therefore, we have to find new methods in order to be able to use the total singlet and triplet excitons population and to achieve 100% internal efficiency. If we can extend the internal efficiency to 100%, this will lead to efficient production of OLEDs in the industry. In this work, to consider increasing excitons’ population, we have worked on the uniformity of the Electron Transport Layer (ETL) and Emissive Layer (EL) by applying argon atmosphere pressure cold jet plasma. Examining the experimental data in comparison with the theoretical data has shown us that having a better uniformity in barriers (based on AFM images) and decreasing contact angle will lead to a better injection and more exciton's population leading to an increase in the internal efficiency.

Features of application of ORC-technology at compressor stations of metallurgical enterprises

The use of secondary energy resources in metallurgy with their conversion into mechanical and / or electrical energy allows not only to reduce the negative impact on the environment, but also to significantly increase the energy efficiency of facilities. As a result the study design, the results of which are presented in this article defined the energy-saving potential at the compressor station metallurgical enterprises (on the example of the system of supply of technical gases of the process of production of rolled steel from iron ore PJSC Magnitogorsk Iron and Steel Works). A schematic solution and a method for determining the operating parameters of an installation operating according to the so-called "organic Rankine cycle" (ORC installation), which allows obtaining additional electrical energy for production needs by utilizing the heat of interstage cooling of compressor units, are proposed and justified. The features of the implementation of this technology are identified, and the working substance of the ORC installation that meets the requirements of safety and energy efficiency as much as possible is proposed for implementation. The values of the internal efficiency, the power of the ORC installation and the share of usefully utilized heat in the implementation of the proposed scheme are estimated.
