An overview of existing urban software mobile applications of the transport and economic direction is given. A model of a functional rationalizer of consumer behavior is being built. The software model of the functional rationalizer of consumer behavior (SM FRCB) was developed for the first time. PMFRCB allows the user to expand the number of his preferred needs (occupations, activities) during the daily cycle through intelligent recommendations. Also, SM FRCB allows you to optimize needs (activities, activities) at the cost and rate of their use. The SM FRCB is made in Python_3 using the libraries matplotlib, collections, numpy, pyplot, mplot3d. The analysis of consumer behavior before and after using the functional rationalizer model is carried out. The graphical results of a structural analysis of the costs of old and new consumer behavior, analysis of consumer behavior within the boundaries of the theory of possibilities and the model of transport behavior of a resident before and after applying the functional rationalizer model are presented. The prospects of further improving the SM FRCB are considered. © 2020 IEEE.

With the achievement on the additive manufacturing, the mechanical properties of architectured materials can be precisely designed by tailoring microstructures. As one of the primary design objectives, the elastic isotropy is of great significance for many engineering applications. However, the prevailing experimental and numerical methods are normally too costly and time-consuming to determine the elastic isotropy of architectured materials with tens of thousands of possible microstructures in design space. The quick mechanical characterization is thus desired for the advanced design of architectured materials. Here, a deep learning-based approach is developed as a portable and efficient tool to identify the elastic isotropy of architectured materials directly from the images of their representative microstructures with arbitrary component distributions. The measure of elastic isotropy for architectured materials is derived firstly in this paper to construct a database with associated images of microstructures. Then a convolutional neural network is trained with the database. It is found that the convolutional neural network shows good performance on the isotropy identification. Meanwhile, it exhibits enough robustness to maintain the performance under fluctuated material properties in practical fabrications. Moreover, the well-trained convolutional neural network can be successfully transferred among different types of architectured materials, including two-phase composites and porous materials, which greatly enhance the efficiency of the deep learning-based approach. This study can give new inspirations on the fast mechanical characterization for the big-data driven design of architectured materials. Copyright © 2020, The Authors. All rights reserved.

Air infiltration induced inter-unit dispersion and infectious risk assessment in a high-rise residential building

Identifying possible airborne transmission routes and assessing the associated infectious risks are essential for implementing effective control measures. This study focuses on the infiltration-induced inter-unit pollutant dispersion in a high-rise residential (HRR) building. The outdoor wind pressure distribution on the building facades was obtained from the wind tunnel experiments. And the inter-household infiltration and tracer gas transmission were simulated using multi-zone model. The risk levels along building height and under different wind directions were examined, and influence of component leakage area was analysed. It is found that, the cross-infection risk can be over 20％ because of the low air infiltration rate below 0.7 ACH, which is significantly higher than the risk of 9％ obtained in our previous on-site measurement with air change rate over 3 ACH. As the air infiltration rate increases along building height, cross-infection risk is generally higher on the lower floors. The effect of wind direction on inter-unit dispersion level is significant, and the presence of a contaminant source in the windward side results in the highest cross-infection risks in other adjacent units on the same floor. Properly improving internal components tightness and increasing air change via external components are beneficial to the control of internal inter-unit transmission induced by infiltration. However, this approach may increase the cross-infection via the external transmission, and effective control measures should be further explored considering multiple transmission routes.

Curcumin, a natural polyphenolic compound with well-documented anti-inflammatory, antioxidant, and anticancer properties, has gained attention for its potential in tissue regeneration and other biomedical applications. Despite this, the integration of curcumin into polymeric scaffolds remains challenging due to its hydrophobic nature and stability concerns. This study aims to overcome these limitations by developing and characterizing curcumin-loaded polycaprolactone (PCL) scaffolds through electrospinning, a technique selected based on a comprehensive review of recent advances in the field. In this work, PCL scaffolds were fabricated with curcumin concentrations of 1.2 wt.%, 2.4 wt.% and 3.6 wt.% and analyzed using advanced microscopy, spectroscopy, thermogravimetry, mechanical testing, and biological assays. Microscopy revealed that increasing curcumin concentrations improved fiber diameter uniformity and distribution. Raman spectroscopy confirmed the homogeneous incorporation of curcumin within the scaffolds, showing that up to 2.4 wt.%, the electrospinning process induces a transition of curcumin from its di-keto to its more reactive keto-enol form. This transformation facilitates hydrogen bonding with the PCL matrix, enhancing the scaffolds' mechanical properties. In vitro cytotoxicity assays demonstrated high cell viability across all scaffolds after 24 and 72 hours. Furthermore, adhesion studies with fibroblast BJ-1 cells indicated significantly improved cell adhesion on curcumin-loaded scaffolds compared to pure PCL. These findings highlight the biocompatibility and bioactivity of curcumin-loaded PCL scaffolds. This study examines the possible use of curcumin's controlled integration into PCL scaffolds for tissue regeneration applications. The innovative approach detailed here offers a scalable and effective pathway for the development of biomaterials that combine mechanical strength, bioactivity, and biocompatibility, addressing a critical need in

Some issues concerning the repair and chemical protection methodology of ammonium nitrate granulation RC technological tower shaft №1 of M-9 workshop PJSC "Azot" in Cherkasy was described. Variants of primary and secondary structures corrosion protection are given. Concrete deterioration and defects of secondary protection of concrete are described. It was revealed that during the initial inspection of ammonium nitrate granulation RC technological tower structures, the tower №1 concrete condition in a number of sections has both surface and through destruction. According to the technical assessment results and calculation analysis, which revealed the practical absence of RC tower trunk bearing capacity reserves, the design of its strengthening was proposed. It was implemented by a system of vertical and horizontal RC stiffeners for the possibility of its overhaul. A technological repair works sequence roadmap was developed. Sika Group offers a system of internal and external concrete surfaces chemical protection of tower trunk. Repair and chemical protection against aggressive influences on an internal and external surface of a RC trunk wsa offered. The use of concrete inside and outside continuous chemical protection system of tower trunk has shown that Sika’s innovative products and innovative repair systems and technologies are making inroads in the practice of construction production in the absence of a regulatory framework.
