The invention enables efficient continuous and fully automated construction progress monitoring in real time, inside and outside the building under construction, without additional work activities, as the wearable devices are installed on all work equipment contributing to the construction. It is a fully automated system that enables the acquisition of 3D data using wearable devices and to identify elements based on their geometry in the 3D digital model of the building. The wearable devices are equipped with a 3D scanner…

Classical methods of cleaning oil spills do not give satisfactory results in removing oil from water, but the functional nanomaterials show the potential to be able to become cost effective and environmentally friendly solutions. The invention is based on the problem of how to synthesize nanoparticles so that they will have such physicochemical properties that will be useful for the adsorption of oil stains / spills in water. The nanoparticles are supposed to have an iron oxide spinel crystal structure…

The present invention relates to an axisymmetric chiral auxetic structure. The invention belongs to the field of materials design. The invention is an axisymmetric chiral cellular structure with a cylindrical or spherical shape consisting of equal or variable unit chiral cells. The structure exhibits auxetic deformation behaviour with negative Poisson’s ratio in all polar or spherical coordinate directions upon mechanical loading. The deformation of the cylindrical chiral auxetic structure is isotropic in the radial direction under axial loading.

Removal of dye from originally dyed textile garments and their transfer and disposal to other uncoloured (white and light coloured) garments present in the same wash bath during washing is known as “dye re-deposition” and is one of the most common problems encountered when washing clothes. Another problem with laundry is the removal of microbiological contaminants, which is becoming critical with the increasingly used low washing temperatures and the use of detergents without aggressive bleaches, due to the pursuit of…

In modern multi-storey prefabricated wooden construction, there is an increasing tendency to use an increased proportion of glazing, which is located primarily on the south side of the building. As a result, due to the stated asymmetry in the stiffness of the wall elements, such floors are distorted, which escalates as a problem especially with the increased number of wooden structures located in highly active seismic and windy areas. The main purpose of the invention is to develop a load-bearing…
