RESEARCH OF CONSTRUCTIVE-TECHNOLOGICAL PARAMETERS OF WORKING BODY FOR SCATTERING BULK MATERIALS

Machines used in world practice for surface application of mineral fertilizers are often equipped with centrifugal devices with vertical or horizontal location of the axis of rotation. Having high productivity and reliability of technological process, they cannot always provide reception of a necessary dose and uniformity of scattering of fertilizers on width. In Ukraine, currently produced machines for the application of mineral fertilizers, which we have not previously produced. Since about 2/3 of all available mineral fertilizers, as well as most of the limestone and gypsum-containing materials are applied in a continuous manner, it is necessary to have a certain fleet of machines for applying fertilizers available to consumers. Fertilizer application in a continuous manner is carried out by land and aviation. One of the main agrotechnical requirements for machines for the application of bulk materials (mineral fertilizers) is their uniform distribution on the field surface. From uneven application of fertilizers, the reduction in grain yield reaches 10 ... 15%. The main disadvantages of the machine for applying mineral fertilizers are: imperfect design of the spreading mechanism, which leads to uneven scattering of fertilizers on the field surface; a large number of gears, which affects the metal content and cost of manufacture and complicates the design. Chain transmissions that drive the spreading device and the conveyor (during operation the chain is stretched, which requires the use of tension rollers, and take-off from the sprockets, especially on the drive of the spreading device); significant uneven application of fertilizers due to imperfect design of the spreading disc. The main reason for the low quality of fertilizer distribution by scattering machines, most researchers see a significant impact on the technological process of external random factors: field relief, wind speed and direction, humidity, elastic, frictional, hygroscopic and particle size distribution of fertilizers. Therefore, the improvement of the technological process of fertilizer scattering, in order to ensure a given uniformity of their distribution on the field surface in the conditions of real functioning, is an urgent scientific and practical task. In order to eliminate these shortcomings, a new spreading working body is proposed.

The Development of a Modified Design Chain Operations Reference Model in New Product Development of the Printed Circuit Board: A Case Study

New product development (NPD) is a process of interactions among multiple parties. With stronger competition in the electronic product market, reducing NPD cycle time has become a common important subject in the information technology (IT) industry. The main topic of this research is process improvements in the research and development (R&D) department of the case company by studying how product competitiveness can be enhanced in the current rapid proceeding technology industry. The process-oriented and hierarchical structure is used to analyze the processes of a new printed circuit board (PCB) design and test, and then a modified design chain operations reference (DCOR) model is introduced to explore problems and suggest corresponding solutions. This research also specifies a clear design chain structure for the case firm and improves its R&D process by brainstorming. The goal is to increase the case firm’s PCB design chain efficiency by shortening the delivery time and reducing the problems of risks arising during the NPD. Finally, this research reviews the essence of the design chain management, draws conclusions, and points out directions for future research.

Retransmission of Historical Lace Ornaments Using 3D-design Method

In this article, it is shown the solution of a range of important issues that are necessary for working out of the modern digital stages of a lace costume and lace–like structures. The most complete study of the historical–cultural heritage of lace is a prerequisite for the construction of a classification matrix that highlights the dominant types of lace in certain time intervals in different countries. Understanding the conditions of traditional design of a lace element with an ornamental pattern, historically natural to its time, allows recreating a certain prototype of a lace element, lace costume, lace style image. The classification matrix provides the possibility of authentic adaptation of historical lace ornaments using the 3D printing method and 3D modelling programs. On the basis of selected historical prototype sketching of the interested area of a costume is carried out from the historical art canvas according to the actual measurements of the elements and the mathematical law of similarity, with a subsequent 1:1 scaling. The copy of maximum possible similarity of the historical prototype with the use of special 3D-programs is transleted from the flat intangible artifact of the great artist into a real stylized 3D-object. Through such modular elements, it is possible to assemble a full-value historical costume or a futuristic style image. In this research is carried out retransmission of the rapport elements of women’s and men’s costume collars. The table shows the key steps in the development of historical prototypes of 3D modules in Adobe Photoshop and Autodesk 3ds Max programs. From the designed modules according to the author’s principle, models of women’s and men’s costume in the style of futurism have been developed. The final models in the costume design chain show a complete difference in costume style and purpose from direct historical prototypes, which proves the absolute adaptive ability of lace to the changing conditions of the existence of the costume.

So that it can build some major key processes assessing several types of economical frames. Study Design: Chain Phenomena Analysis Place and Duration of Study: University of Guadalajara, Physics Department, Data Science Group. Results: Model exposition. Conclusion: I show how, as long as time change currently, social interaction impact on economical framework has become bigger. Big Data tools to manipulate high volume levels of information from this interactions have been a strongest platform to analyse economical indicators, such as those which repercussions affects financial stock markets. This process is modelled in this article.

Design chain visibility

Purpose Researchers ascertain that the more the activities of new product development (NPD) process are outsourced to partners, the higher the need for integration. The purpose of this paper is to study: the extent to which the amount of information shared with the partners during NPD projects (DC visibility) depends on the degree of outsourcing (DC virtuality), and what are the context variables (product features and business relationship features) that influence this relationship. Design/methodology/approach This paper provides two sets of quantitative indexes to measure: the relevance of the activities outsourced during the NPD project (i.e. virtuality), in terms of the spread of the outsourced technological knowledge, and in terms of outsourced workload; and the amount of information that a focal company shares with product development partners (i.e. visibility). Seven NPD projects in different companies have been analyzed to investigate visibility, virtuality, and the implications of contingencies. Findings The cross-case analysis shows that the amount of information shared with the partners during the NPD project varies with the relevance of outsourced activities. In particular, the higher the relevance, the higher the amount of information shared with the partner. Partner location and integration, trust, and ICT support have a role in determining the amount of information shared with each single partner. Originality/value This study adopts an original network perspective in that the whole set of partners involved in the NPD process is analyzed. New quantitative indexes of visibility and virtuality of NPD projects are proposed, along with original insights about the impact of context variables. The quantitative indexes also provide a useful managerial tool to evaluate whether a focal company has the possibility to build competitive advantages that exploit unique resources beyond the boundaries of the company.
