In order to ensure the sustainability of social housing, the living conditions should meet basic biological needs [demands], but they should also have a stimulating effect on the psycho-social development of the users. The focus of the research is on identification and definition of the physical and spatial criteria that are essential for the quali...

This paper analyses the problem of estimating the required quantities of major work items in the construction of residential and residential-commercial buildings using machine learning algorithms. The goal is to form a model that will provide a fast and sufficiently accurate estimate of the quantities of major work items, based on a small amount of...

The salon apartment is a residential typology that developed in Serbia from the middle of the 19th century until the beginning of the Second World War. The spatial-functional organization of the salon apartment is characterized by typological characteristics such as: division of space into two zones, salon, central room, pass-through dining room, e...

Large amounts of data are collected on space bodies, and all data is available to all users free of charge through various archives and portals. When searching for data, especially non-space scientists, often have problems because the archives are tailored to meet only space experts needs. Prior knowledge about missions is necessary to search data ...

The paper discusses how the dispersed urban form of Banja Luka (Bosnia and Herzegovina) is related to the collective housing form that emerged during the 20th and 21st centuries. The morphological study resulted in the typological patterns of collective housing form based on the relationship between the house and open space and follows its transfor...

We propose a research of geoids as real hypersufaces. Moreover, we give adjustment of some classical results on hyperusrfaces to CR submanifolds. Our main focus is to study the properties of second fundamental form which give us information on the shape of a hypersurface. Keywords: geoids, hypersurfaces, shape operator, CR submanifolds....

It is assumed that the porous material is based on the principle of conservation of mass and the principle of conservation of energy. The validity of both principles relies on experimental observations. Experimental results of different metals were used to compare the Poisson ratio as a function of porosity. A comparison is made between the theory ...

In this paper, expanded polystyrene (EPS) lightweight concrete (LWC) was investigated. The mainaim was to design EPS LWC with the specified density of 1200 kg/m3 according to standard concretemix proportion. Mix proportion included total replacement of the conventional coarse aggregate bymaximum possible amount of EPS beads, which ensures concrete ...
