BIM (Building Information Modelling) is a tool and technology closely related to the planning, design, implementation and management of construction investments – both at the level of a building, as well as infrastructure or civil engineering. It combines advanced spatial modeling (using virtual representations of building elements) with management of information at every level, from the modelling of building’s components, through complex interactions between these elements, to the description of building processes and the behavior of users of the building. This is just a part of many possibilities, the full application depends only on the needs and skills of the system user. Construction dependencies are set at the level of the IFC (Industry Foundation Class) universal standard IFC, its syntax allows to describe not only the physical structure of the object, but also their mutual interactions. This is done in a hierarchical way, i.e. from the superior element there are subsequent, lower-level elements and interactions. So how can this tool be used in urban revitalization? The basic problem here is the excess of information related to and contained in the virtual model. In urban planning and design, most of this data is unnecessary. On the other hand, the data contained in the GIS (Geographic Information System) models, despite correlation with external databases, are insufficient. Basic location data, technical conditions of facilities and infrastructure, property dependencies are not enough to obtain a full picture of the urban space. The solution to the problem of linking these systems is CIM (City Information Modeling). It combines the description of an object derived from IFC with database support at the level of GIS systems. Such a broad approach allows for placing enough information in one virtual space for designing, modeling and analyzing urban space. The article is an attempt to demonstrate what conditions must be met by the CIM system, to extend its functionality to issues related to the revitalization of urban areas: whether and how the information contained in the spatial model can be used to determine the rules for the revitalization of space at the urban level?

Author confronts various problems the historian of mentality has to deal with, basing on the last decade publications by Polish scientists.

The Author confronts various opinions on king James II and Restauration era, presented in numerous Histories of England published over the period of one and a half of century after the Glorious Revolution

Poland is a significant producer of vegetable sprouts, which, due to the high content of nutrients, are produced for food purposes. The cultivation cycle of these plants, especially the mung beans (Vigna radiata), is associated with significant exploitation of natural resources (as much as 275 dm3 of water per 1 kg of dry seeds) and requires appropriate temperature conditions. However, since producing of vegetable sprouts is an exothermic process, there are reasons to organize the growth conditions of these plants in a quasi-autonomous manner. Estimated preliminary studies show that during the entire period of sprout growth, as much as 2.86 MJ of heat from 1 kg of dry seeds can be used, which, taking into account the scale of production of these plants, places them among the significant sources of low-temperature waste heat. The paper presents the results of temperature measurements carried out in a growth chamber used for the industrial production of the mung bean vegetable sprouts. Based on the prepared energy balance, the total amount of heat generated (4.9 GJ) and recovered (3.3 GJ) in the seed germination process was determined. The amount of energy lost in the process of imbibition and the amount of heat needed to ensure optimal plant growth conditions were determined. The study shows that the use of low-temperature heat generated by plants allows for a significant reduction in the energy consumption of the production process.

The paper presents an analysis of the effect of shape of primary silicon crystals on the sizes of stresses and deformations in a surface layer

of A390.0 alloy by Finite Elements Method (FEM). Analysis of stereological characteristics of the studied alloy, performed based on a

quantitative metallographic analysis in combination with a statistical analysis, was used for this purpose. The presented simulation tests

showed not only the deposition depth of maximum stresses and strains, but also allowed for determining the aforementioned values

depending on the shape of the silicon crystals. The studied material is intended for pistons of internal combustion engines, therefore the

analysis of the surface layer corresponded to conditions during friction in a piston-cylinder system of an internal combustion engine having

power of up to 100 kW. The obtained results showed important differences in the values of stresses and strains up to 15% between various

shape of the silicon crystals. Crystals with sharp edges caused higher stresses and deformation locally than those with rounded shapes.

Five models and methodology are discussed in this paper for constructing classifiers capable of recognizing in real time the type of fuel injected into a diesel engine cylinder to accuracy acceptable in practical technical applications. Experimental research was carried out on the dynamic engine test facility. The signal of in-cylinder and in-injection line pressure in an internal combustion engine powered by mineral fuel, biodiesel or blends of these two fuel types was evaluated using the vibro-acoustic method. Computational intelligence methods such as classification trees, particle swarm optimization and random forest were applied.
