“…The word "urban furniture" was developed in Europe in the 1960s. The term is defined differently, as private or public furnishings in public spaces that provide certain services and perform various public functions [2]. The Cambridge Dictionary defines urban furniture (street furniture) as objects and equipment installed for various purposes along streets and roads (dictionary.cambridge.org).…”

“…The Cambridge Dictionary defines urban furniture (street furniture) as objects and equipment installed for various purposes along streets and roads (dictionary.cambridge.org). Yang [2], recognising that the English term can be misleading and understood as fixtures present only on the street, developed a definition of street furniture according to the five elements analysed in Lynch's [3] study. He included the following: (a) roads-lines along which we move, such as paths, streets, crosswalks, and railroads; (b) edges-lines that are barriers, linear elements such as rivers, railroad embankments, and walls; (c) areas-medium-to-large sections of the city, e.g.,: neighbourhoods and parks; (d) nodal points-intersections, places where spaces in the city intersect; and (e) landmarks, and he considered these to be urban furniture.…”

Urban furniture is a wide collection of objects of different sizes and geometries, performing different functions in the city. The paper describes the history and contemporary development trends of urban furniture. It analyses the construction materials most often used in their production, as well as functional and aesthetic solutions. A questionnaire survey, exploring the issue of urban furniture from the view point of the student population, was statistically analysed. It showed the preferences and expectations of current and future users of urban furniture, which can be helpful in achieving harmony between the creation of a positive image of the city and the comfort of public spaces for its residents. In the study of the preferences of urban furniture users, contingency tables were used for questions with a possible single answer. The results of questions with possible multiple answers were illustrated using Venn diagrams or equivalent UpSetR charts.

Approximate calculation in engineering technology, production and living and so on all aspects and its important role, the specific production technology of the values are approximation, it always inseparable from the approximation calculation. We extrapolated the calculation examples of approximation into research. This paper expounds the approximate calculation of the approximate function of the basic important role and its basic types.

“…Gum et al patented a process in which energy consumption is reduced by using a thin layer of gold inside the reactor chamber. Liu et al developed a low energy consumption polysilicon CVD reactor and described various transport phenomena in the reactor using a computational fluid dynamics (CFD) method. Moreover, Vigano et al presented a technique for a real‐time model‐based predictive control applied to a laboratory‐scale Siemens reactor, and used a lumped model to describe the CVD process.…”

This study proposes a novel process in which multiple polysilicon chemical vapour deposition (CVD) reactors are connected in series, and this setup is investigated using computational fluid dynamics (CFD). A three-dimensional CFD theoretical model is proposed to describe the various transport phenomena in the reactor, and this model is validated by comparing the reactor outlet temperatures of the simulation results and the data obtained using an industrial polysilicon CVD reactor. This model was then used for analyzing the production cost and growth rate of the traditional and proposed CVD processes. The simulation results show that the polysilicon production cost in the traditional and proposed processes is lowest for 0.091 mol/mol (9.1 mol%); the maximum deposition rate is achieved for 0.25 mol/mol (25 mol%). On the other hand, if the operation pressure increases from 101 to 607 kPa, the average production cost can be reduced from 86.26 to 39.88 $/kg; and the average growth rate can be raised from 1.68 to 4.18 mm Á min À1. In addition, compared with the 1-reactor process, the cost of the 2-reactor process is 21.9 % lower, and the 3-reactor process is 26.9 % lower. Finally, in the novel process, changing the chlorine hydride of the feed in the reactor 2 from 0.1 g/g (10 wt%) to 0.02 g/g (2 wt%), the average production cost can be reduced by 35.5 %.
