AbstractRoutine millimagnitude photometry may require a new approach to reduction of photometric errors. Such an approach is outlined in this paper; it stresses elimination of each error as close to its source as possible. The possibilities provided by modern technology are reviewed in this light. An engineering design group dedicated to photometry is a prerequisite and an on-site photometric technician may be necessary. In this concept, observers are mainly remote users of a database. Implied is the idea of accurate photometry necessarily developing into a single but multi-site astronomical facility (cf. VLBI) and the communal discipline that goes with it.

The article examines the conditions and features of the formation of an idea for the development of a modern product, modern technology or a new vector of development of entrepreneurial activity on the platform of design thinking. This category - design thinking should become one of the main areas of business development, startups and creating a comfortable environment not only in business but also in the organization of public programs and decisions, the organization of municipal economy, as well as management at the state level. Any startup begins with the formation of the idea. It should not be just an idea, but the idea that can change the world, change people's lives for the better. A mandatory condition for the development of the country's economic system is the development of the entrepreneurship. During the political reorientation of our country, changes in the economy are taking place primarily through the introduction of new ideas. Based on the existing issues of business organization, entrepreneurship development and especially the creation of startup projects in Ukraine, requires clarification of the peculiarities of the development of startups based on a new approach - design thinking. Requires research and further clarification of the application of design thinking in the work of enterprises, the use of innovative approaches to the organization of both new forms of business and the improvement of existing relationships and business processes. The purpose of the article is to study the conditions and features of the formation of the idea for the development of a modern product, modern technology or a new vector of business development on the platform of design thinking. Of course, these changes require the promotion of more competitive products created using innovative approaches, there is the implementation of a startup. Many methods can be used to understand the real problem and its causes. It is worth to analyze the problem. The analysis of the problem better provides understanding of the problem before starting work with it. Even at the stage of the problem formulation, may arise a lot of questions connecting with people perception, misunderstanding, and vision of its solutions. A fundamentally new approach of solving the problem is the design thinking. The design thinking is a method of creating products and services that are focused on the person. It is the process when researchers try to understand the consumer problems, to make assumptions and to check them, to change the problem statement and try to find alternative strategies and solutions. The design thinking basis is the empathy and the ability to form schematic images in the imagination to further identify patterns and generate ideas with emotional and functional content. Empathy is a broad concept that refers to a person's cognitive and emotional reactions to another's experience. The empathy benefits to build and rebuild relationships. On the other hand, through support we acquire the skills of better regulation of personal emotions, especially using such useful and valuable experiense in stressful circumstances. This determines another property of empathy - it promotes the development of healthier and more meaningful behavior. Implementing business ideas creates additional opportunities for businesses. This process begins with a specific problem - a task for design thinking. This task must be accessible, understandable and feasible. Solving this problem will meet the needs of consumers, solve their problem, and create a new, unique product that is in demand. The development of startups, business organizations, the work of enterprises on this principle will provide significant benefits, and will be more successful and competitive.

Abstract Problems in the field of engineering design represent an important class of real world problems that typically require a fuzzy and imprecise representation. This article presents and discusses a new approach to model this type of problem, by incorporating linguistic descriptions together with a variety of user-defined trade-off strategies. An interactive computer application is introduced, using stochastic optimization to solve the design task by producing a specially desired output under the given environmental conditions which are partly caused by the personal preferences of the engineer and by the expectations of the customer. It utilizes a randomized evolutionary technique, made suitable for the class of problems at hand, to generate and to optimize design solutions that are later identified by a clustering algorithm. Moreover test problems that were solved by the application are considered. In all cases the good solutions were obtained by evaluating only an extremely small fraction of all possible designs.

This paper describes a new approach to teaching first year design at Memorial University. Students are introduced to engineering design using the product realization process (PRP) as a platform. The course integrates the business, engineering design, and prototyping functions of the PRP. The just-in-time structured delivery of background tools and theory complement the relatively unstructured nature of the design problems. Lab exercises are used to intoduce the basic practicalities of mechanical, electrical and electronic design. Projects are completed in teams with emphasis placed on teamwork, project management and communication skills. Student enthusiasm has been very high and this aides significantly in the learning process.

Recent theoretical developments linking degradation to the thermodynamic concept of entropy have allowed a new approach to modeling all types of degradation. The theory has been successfully applied to wear, fatigue, and numerous other forms of degradation and experimentation has confirmed its applicability to modeling the mechanical degradation of lubricating grease. This paper overviews the mechanical degradation of grease, discusses past and present modeling techniques, shows how new techniques can be used to predict grease life, and provides suggestions for future research.

PurposeThe purpose of this paper is to develop a new approach to investigate complex processes, such as software development processes, using business process modeling.Design/methodology/approachThe paper presents an investigation into the use of role activity diagramming (RAD) to model complex processes in the software industry sector, with reference to the process of TestWarehouse as a case study.FindingsSystematic extension and quantitative analysis to RAD models led to the discovery of process bottlenecks, identification of cross functional boundary problems, and focused discussion about automation of processes.Research limitations/implicationsFurther work is required to validate and evaluate the proposed approach using several cases with different application domains and thus generalize the adopted approach.Practical implicationsA new approach has been used successfully to understand and analyze business processes. The tools and techniques that are used to perform the approach are not complicated and do not need much specialist expertise, so the approach is not only oriented toward specialists but also toward organizations' managers and staff.Originality/valueNew techniques have been developed by using process modelling to deepen the understanding and analyzing of complex organizational processes. This research implements a practical investigation which uses a case study to validate the new techniques.

The anomalous position of probability and statistics in both mathematics and engineering is discussed, showing that there is little consensus on concepts and methods. For application in engineering design, probability is defined as strictly subjective in nature. It is argued that the use of classical methods of statistics to generate probability density functions by estimating parameters for assumed theoretical distributions should be used with caution, and that the use of confidence limits is not really meaningful in a design context. Preferred methods are described, and a new evolutionary technique for developing probability distributions of new random variables is proposed. Although Bayesian methods are commonly considered to be subjective, it is argued that, in the engineering sense, they are really not. A general formulation of the probabilistic optimization problem is described, including the role of subjective probability density functions.

AbstractThe liquidus temperature of a waste glass (the temperature at which the system glass + crystalline material is in equilibrium with the amorphous glass of the same composition) often is a measure of the solubility of a specific component in the waste in the base glass. A new approach toward predicting the liquidus temperatures of waste glasses has been developed based on solubility. The approach predicts liquidus temperature as well as more complicated expressions developed by other researchers. At the same time, simple process control limits can be easily derived from this model, which is difficult to do with other approaches. While the approach is not applicable to all waste glass components, it can be used for important species such as nickel-iron spinel, chromium oxide, and probably plutonium dioxide. The approach also has led to two new techniques for determining liquidus of waste glass systems.
