Point cloud segmentation and classification of structural elements in multi-planar masonry building facades

Multi-planar building facades, pose significant challenges to existing point cloud segmentation techniques, as most have an underlying assumption that all structural elements appear within only a single plane, which is often untrue. For architecturally complex buildings, this prevents the automatic extraction of the load bearing structure for use in structural engineering applications. To address these deficits, the multi-planar algorithm is introduced as a means to differentiate between structural and non-structural elements for multi-planar facades. The algorithm considers statistically the position of groups of points with respect to their neighbours to identify and segregate the principal facade of architecturally ornate, multi-planar buildings. The viability and robustness of the algorithm is demonstrated through its application to 3 buildings in Dublin, Ireland, which when compared to independent survey data, resulted in 98% accuracy for single complex openings and an overall average accuracy of at least 91%. The superiority of the technique is demonstrated against four prominent segmentation techniques and through the application of the output files into an ANSYS finite element model.

Optimization of the structure of insulating composite materials

The article deals with the interdependent relationship between the properties of a structure and the properties of a material, which sets the task of reducing them, even they are indistinguishable, to a certain integrity. The object of research and analysis in the article is a building structure, which is seen as an open self-organized complex structural system. In the main part, the processes of the formation of structures are considered, as well as the classification of structural elements. The article concludes with structural changes related to the self-support and self-development of the network of active elements, which allow the manifestation of adaptation effects and the design-system to function during the normalized period. The importance of self-organization processes during the development and operation of construction systems allow us to attribute it to a self-organizing system. Thus, the building structure can be represented as an open and complex self-organizing system.

Systematics and improvement of classification of resource base of the bank

The article analyzes and summarizes the main approaches to classification of constituents of resource base of banks and taking into account that it is proposed the generalized (integrated) classification of the resource base of commercial banks. Particular attention is paid to the specific types of components of the resource base of the bank. It is grounded limited interpretation of the term structure of the resource base in the economic literature and formulated its own definition as the ratio between the individual items of equity and bank liabilities (raised and borrowed funds) and between different elements of the resource base of the bank as a whole in order to ensure stability and reducing investment of raised and borrowed resources.Based on existing approaches to classification of structural elements of the resource base of the bank, it is developed their classification by the most essential features that can solve the strategic objectives of the bank on sourcing resource base with minimal cost to implement active operations in certain directions and volumes and aimed at efficient use and management of the resource base. It is introduced an additional criterion for classification of bank resources for their functionality, whereby they are three components: resources to formation of portfolio of earning assets; resources to create material, technical and technological base of the bank; resources to self-insurance of bank from banking risks.

Graph model for calculating the properties of saturated monoalcohols based on the additivity of energy terms

A 16-constant additive scheme was derived for calculating the physicochemical properties of saturated monoalcohols CH4O-C9H20O and decomposing the triangular numbers of the Pascal triangle based on the similarity of subgraphs in the molecular graphs (MGs) of the homologous series of these alcohols. It was shown, using this scheme for calculation of properties of saturated monoalcohols as an example, that each coefficient of the scheme (in other words, the number of methods to impose a chain of a definite length i1, i2, … on a molecular graph) is the result of the decomposition of the triangular numbers of the Pascal triangle. A linear dependence was found within the adopted classification of structural elements. Sixteen parameters of the schemes were recorded as linear combinations of 17 parameters. The enthalpies of vaporization L298 K0 of the saturated monoalcohols CH4O-C9H20O, for which there were no experimental data, were calculated. It was shown that the parameters are not chosen randomly when using the given procedure for constructing an additive scheme by decomposing the triangular numbers of the Pascal triangle.
