Abstract

Spatial and time diversity of housing construction in Poland. Residential housing construction, as one of the most important elements of spatial development, a factor decisive for living conditions of residents, is the object of interest not only of architects, planners or local and state authorities, but increasingly also of geographers, who mainly analyze these issues in a spatial context. The article analyzes the development of construction in post-war Poland in three periods: real socialism, the transformation period and the last decade. The subject of the analysis is the number of completed dwellings/flats in total, by location (city, village) and by investors (housing cooperatives, developers, private constructors and others).

Abstract

The increment in the number of automobiles and the densification of the city has increased noise pollution rates. In addition, the lack of regulation in Chile regarding the acoustic insulation of façades is a problem of a growing concern. The main objective of the present study was to obtain a model of the Sound Insulation of housing, façades, stratified in Santiago, Chile, based on constructive variables. It is expected to serve as a basis for one future regulation for acoustic façades of houses. In the present study, tests based on the international ISO 140-5 standard were carried out in situ. An estimation model of the Standardized Level Difference Dls,2m,nT,w + C, was obtained based on the opening/façade proportion, and the type of glass used for the windows.

Abstract

The analysis of the fractal dimension becomes one of the new approach features in spatial research. This approach bases on the perception of space as a living structure, an organism which in its complexity and heterogeneity is a multi-scale creation although holistically perceived. The aim of the authors was to determine the nationwide fractal dimensions for the distinguished construction categories and designation of general regularities in these layout.

Abstract

According to UNESCO, in 2015, the sculpture as the artistic medium was third among financed public residency art programmes. Contemporary public art and cultural programmes across Europe were focused on finding a balance between cultural identity and cultural diversity among the communities. Therefore, aesthetics and function became a significant issue related to the exploration of participatory design on public sculpture. In this paper, an adopted model of Kurt Lewin’s force field analysis was used to explore the function of sculpture in the public space. The aim was to further evaluate inclusive design to answer the question: Does contemporary sculpture in the public space evoke a certain kind of group dynamic process?

Abstract

Adopting the standpoint of Construction Grammar (Goldberg 2006) and the corpus- based method known as Distinctive-Collexeme Analysis (Gries and Stefanowitsch 2004; Hilpert 2014), the investigation seeks to identify lexemes that indicate a strong preference either for the it is ADJ to V-construction or the it is ADJ that-construction. On the basis of data extracted from the academic sub-corpus of COCA, the study reveals that there are adjectives exhibiting a strong preference for one construction instead of the other, and that the constructions have a tendency to occur with adjectives evoking different semantic frames.

Abstract

This paper concerns the possibility of use the Jiles-Atherton extended model to describe the magnetic characteristics of construction steel St3 under mechanical stress. Results of the modelling utilizing extended Jiles-Atherton model are consistent with results of experimental measurements for magnetic hysteresis loops B(H). Material stress state determination by using non-destructive, magnetic properties based on testing techniques is an especially important problem.

Abstract

The project called “Polish Cardiosurgical Robot” has been developed by Foundation for Cardiac Surgery Development since year 2000. Within the project the telemanipulator to perform the endoscopic cardiosurgical operations has been designed, manufactured and examined. In the following paper the development of construction of arms for RobIn Heart 0, RobIn Heart 1, RobIn Heart 3 versions of the robot as well as the fixing system has been presented. In the preliminary phase of the project the requirements for mechanical construction were analyzed. Additional requirements enhancing functionality of the construction were also defined. Analyses of the planned development of the construction and ways of its possible applications were performed.

Abstract

The work presents the results of the research and tests of the surface machining of the S355NL and X5CrNi18-10 steels with the concentraded stream of heat with the usage of the GTAW method. The surface layers of the tested steels were remelted with the electric arc using the current of the electric arc 50, 100, 150 and 200A.The machining was done in the atmosphere of argon with the constant speed of the welding head. A microscope examination was performed of the obtained structure and measurements of depth, width and hardness of the received surface layer were performed. Moreover the relation between the current of the electric arc and geometry of the remelted layers with their microhardness was examined.

Abstract

Designed by the architect Louis I. Kahn, the Phillips Exeter Academy Library is renowned mostly for the quality of its inner spaces. Particularly, the image of the building's central void with its large circular openings giving an insight onto the bookshelves has almost become an archetype of the library. Following the building's design process, however, we will learn how many tangible factors participated in the actual shaping of its architecture. The uniqueness of this project relies not only on embodying the idea of the library as institution, but also on the compromises the architect took as well as on the building's adjustment to its environmental setting.

Abstract

The convolution operation used in deterministic network calculus differs from its counterpart known from the classic systems theory. A reason for this lies in the fact that the former is defined in terms of the so-called min-plus algebra. Therefore, it is oft difficult to realize how it really works. In these cases, its graphical interpretation can be very helpful. This paper is devoted to a topic of construction of the min-plus convolution curve. This is done here in a systematic way to avoid arriving at non-transparent figures that are presented in publications. Contrary to this, our procedure is very transparent and removes shortcomings of constructions known in the literature. Some examples illustrate its usefulness.

Abstract

The purpose of this article is to present a new bell type water well construction with circulating treatment and its application. The construction of the water well has been developed and research has been conducted using physical and electrical modelling as well as in the practical field. Researches in this work are of analytical and experimental character. As the results of the research, optimal physical parameters of the constructions have been found and analytical  empirical formulae have been derived to calculate hydraulic parameters. Recommendation for application has been presented. The results received in this work can be used for the application of well construction. Further research is required to improve the physical and the hydraulic parameters of the proposed construction. The work has scientific and practical interest.

Abstract

This article presents the peculiarities and methodical principles for designing the technologies and forms of organization of the construction liquidation cycle for typical unified series of residential buildings. The systematic approach for developing the necessary settings and indicators of the structure of a complex technological process for disassembling, destructing and demolishing of structural elements and buildings in general is given. The multigraph is created for the closed walk model of correlation of the parameters of the organizational and technological solutions of the construction liquidation cycle.
