To reach autonomous control with good performance in shearer operated longwall mines, control algorithms have to be adapted to the system behaviour. Thus, one of the challenging tasks in this area is the identification of the behaviour, which is declared as complex and specific to each mining area. Therefore, it is necessary to determine a suitable model that reproduces the cut behaviour of a shearer loader and can be adapted to a real mining system. This paper shows and analyses possible model structures to predi...

Since ancient times, chromium oxide was used 2000 years ago by the Chinese to cover the tips of weapons and later, as late as 1988, hexavalent chromium was discovered to be dangerous to humans. Currently, many companies carry out chrome plating of plastic parts, which consists in creating a superficial layer of diffusion, of an iron-chromium alloy with up to 10 - 20% chromium. Coating by electrolytic deposition is the most widely used method for creating protective layers for plastic materials and consists in elec...

Adaptation strategies are highly desirable documents based on more frequently occurring hydrological extremes. These strategic documents are prepared at different levels, the state level on one side and the regional or city level on the other side. The complex approach that was chosen for the Pardubice and Pilsen regions was also applied to the territory of the Dyje basin. Specifically, a multi-criteria analysis was used as a means of selecting priority model areas. Based on the analyses developed from the availab...

Composting municipal organic waste is important for several reasons, including greenhouse gas emissions reduction, soil health improvement, nutrients recycle, waste reduction, costs reduction (by reducing the waste volumes, the handling costs are decreased). Information on the practices of municipal organic waste composting in Romania is limited, thus a comprehensive evaluation of the limiting factors and current solution was carried out. According to the European Environment Agency, Romania has made progress in o...

The incorporation of natural fibres as reinforcement of concrete is attractive from a sustainable perspective. In fact, natural fibres improve the deformation capacity and increase the ductility of concrete. In addition, natural fibres are lightweight, renewable, less expensive than man-made fibres and locally abundant. However, in order to determine their use in different concrete applications, it is necessary to know the impact on the mechanical properties and the benefits that can be obtained by incorporating t...

In 1923 Le Corbusier-s Vers une architecture was published for the first time, maybe the most influential essay for the discipline ever. Imprinted on the title page of that first edition was the photo of the deck of the steamer Aquitaine, at the time the most up-to- date result of the industry: from there, the -machine- became the model for a radical renewal of architecture. Nowadays, in 2023, who would ever dream of presenting the latest cruise ship or a super-jet as a paradigm for a renewed architecture? In fact...
