In recent years, civil engineers have been exploring innovative methods of constructing buildings using environmentally friendly materials. The beneficial properties of hemp harl, an agricultural waste that is gaining popularity in construction, prompted the idea of strengthening its properties through the granulation process and using it as an aggregate in cement composites. This work aimed to investigate whether the use of hemp husk in the form of granules would have a positive effect on the properties of cement composites compared to their traditional form (stems). Potato starch was introduced as an additional factor in the granulation process to improve the material. Experimental tests were carried out on organic fillers, fresh mixtures, and hardened composites. Physical, mechanical, and structural tests (SEM imaging) were carried out. The highest strength was demonstrated by samples containing hemp shive aggregate (1.186 MPa), while the use of hemp shives in the form of granules had a positive effect on the consistency and density, and it also reduced water absorption by 30% during the production of the composite. The apparent density of composites with hemp shives in the form of hemp pellets was higher (1042 ÷ 1506 kg/m3) than in the case of composites with shives in the form of harl (727 ÷ 1160 kg/m3). Nevertheless, hemp shive in both forms can be used as a natural aggregate in cement composites.

This study employs the robust capabilities of Google Earth Engine (GEE) to analyze and forecast land cover and land use changes in the Talas District, situated within the Zhambyl region of Kazakhstan, for a period spanning from 2000 to 2030. The methodology involves thorough image selection, data filtering, and classification using a Random Forest algorithm based on Landsat imagery. This study identifies significant shifts in land cover classes such as herbaceous wetlands, bare vegetation, shrublands, solonchak, water bodies, and grasslands. A detailed accuracy assessment validates the classification model. The forecast for 2030 reveals dynamic trends, including the decline of herbaceous wetlands, a reversal in bare vegetation, and concerns over water bodies. The 2030 forecast shows dynamic trends, including a projected 334.023 km2 of herbaceous wetlands, 2271.41 km2 of bare vegetation, and a notable reduction in water bodies to 24.0129 km2. In quantifying overall trends, this study observes a decline in herbaceous wetlands, bare vegetation, and approximately 67% fewer water bodies from 2000 to 2030, alongside a rise in grassland areas, highlighting dynamic land cover changes. This research underscores the need for continuous monitoring and research to guide sustainable land use planning and conservation in the Talas District and similar areas.

Published: July 2024

Energy harvesting from cleaner sources and preserving the environment from dangerous gasses are presently the key priorities globally to maintain sustainable development. In this context, photovoltaic technology plays a vital role in generating energy from ternary organic solar cells. Ternary organic solar cells display significant potential for achieving outstanding photovoltaic performance compared to binary structures. Over the past few years, significant endeavors to develop novel organic materials have led to a consistent rise in efficiency, surpassing 19% for single-junction devices. In our study, we simulated an inverted ternary organic solar cell (TOSC) structure employing the one-dimensional optical and drift diffusion model and using “Oghma-Nano 8.0.034” software by optimizing the active blend thickness at 80 nm within the structure of ITO/SnO2/PM6:D18:L8-BO/PEDOT:PSS/Ag. We simulated different performance parameters such as EQE, Photo-CELIV, PCE, Jsc, Voc, and FF with different active layer thicknesses ranging from 50 to 200 nm to discover the behavior of the device in terms of efficiency parameters. Furthermore, the structure attained a PCE of 20% for an active layer thickness of 80 nm within a Jsc of 27.2 mA cm−2, a Voc of 0.89 V, and an FF of 82.3%. This approach can potentially be valuable in constructing a highly effective TOSC model in the laboratory.
A Multi-Technique Hybrid Method for the Widening and Splicing of New and Old Beam Bridges
Authors: Tan Zhicheng , Yu Jiangchuan , Zhang Shaoyi
Published: July 2024

With the rapid increase in the urban traffic volume, the traffic capacity of existing bridges could not meet the demands of urban planning in many cities, leading to the problem of reconstruction or expansion. Considering the sustainability principle in bridge structure construction while minimizing the environmental implications of the construction activities, a multi-technique hybrid method for the widening and splicing of new and old beam bridges was proposed. Firstly, according to the stress equations of the splicing interface between the new and old bridges, the control condition for the selection of the splicing materials was found, and a selection method based on the maximum stress at the splicing interface of the materials was proposed. Then, based on the control condition of the foundation settlement of the new bridges, the geometric parameters of the splicing structures, and the mechanical parameters of the splicing materials, equations for the minimum reinforcement ratio were derived according to the allowable stress value of the splicing materials. Lastly, the equivalent analogic orthotropic plate model of the splicing bridges was built, and based on that, a calculation method for the quantity of the splicing diaphragms was proposed. Also, the effectiveness of the proposed method was validated through a reconstruction and expansion project in Guangdong Province. The results showed that the maximum foundation settlements of the new bridges were smaller than the assumption values of the calculation after reconstruction of the old bridges, and no observable cracks were found in the splicing structures. The proposed method could serve as a reference for similar structure designs.

Analyzing the Approximate Error and Applicable Condition of the Fractional Reduced Differential Transform Method
Authors: Hu Jianbing
Published: July 2024

The fractional reduced differential transform method is a finite iterative method based on infinite fractional expansions. The obtained result is the approximation of the real value. Currently, there are few reports on the approximate error and applicable condition. In this paper, we study the factors related to the approximate errors according to the fractional expansions. Our research shows that the approximate errors relate not only to fractional order but also to time t, and that they increase rapidly with time t. This method can only be applied within a certain time range, and the time range is relevant to fractional order and fractional expansions. We can ascertain this time range according to the absolute error and the relative error. Many obtained achievements may be incorrect if the applicable conditions are not satisfied. Some examples presented in this paper verify our analysis.
Gauge Symmetry of Magnetic and Electric Two-Potentials with Magnetic Monopoles
Authors: Cuzinatto Rodrigo R. , Pompeia Pedro J. , de Montigny Marc
Published: July 2024

We generalize the U(1) gauge transformations of electrodynamics by means of an analytical extension of their parameter space and observe that this leads naturally to two gauge potentials, one electric, one magnetic, which permit the writing of local Lagrangians describing elementary particles with electric and magnetic charges. Gauge invariance requires a conformal transformation of the metric tensor. We apply this approach, which borrows from Utiyama’s methodology, to a model with a massless scalar field and a model with a massless spinor field. We observed that for spinor models non-symmetrized Lagrangians can enable the existence of magnetic monopoles, but this is not possible with symmetrized Lagrangian. Such restrictions do not occur for spinless fields, but the model does not allow spin-one fields interacting with monopoles.

The method of radial basis functions for the numerical solution of the partial integro-differential equation in multi-dimensional domains is considered. A linear combination of radial basis functions at specific center points and a linear combination of polynomial basis functions are employed to approximate the problem’s solution. The distribution of the center points is proposed for both two and three-dimensional domains. Collocating at the center points leads to the semi-discretized system that contains integral coefficients. Integral coefficients are calculated numerically using the Gauss-Legendre and trapezoidal quadrature rules. A shape parameter is determined by a real-coded genetic algorithm. Numerical results both in two- and three-dimensional domains confirm the applicability of the proposed approach. Keywords: elliptic partial integro-differential equation, radial basis functions, polynomial basis, genetic algorithm.

The paper examines the effectiveness of threshold and non-threshold wavelet noise filtering methods in processing radar signals. Three methods of wavelet analysis are analyzed: a method with a general threshold for limiting wavelet coefficients of detail; a method with a universal threshold for all wavelet decompositions; and a method without a threshold, based on zeroing the coefficients of detail at certain levels of the wavelet decomposition of the signal. The effectiveness of wavelet filtering is evaluated by the signal-to-noise ratio before and after filtering, signal entropy, and the model’s mean square error (MSE) value. It is found that over a wide range of high noise from –12 dB to –7.5 dB, the common threshold method provides more effective noise filtering than other methods.

The problem of convergence of controlled objects with different inertia in dynamic game problems is considered. For controlled objects with different inertia, it is characteristic that the Pontryagin condition is not satisfied on a time interval. To solve the problem, a special multivalued mapping and a matrix function are introduced to equalize the players’ control resources, and then the additional resource is compensated by the body component of the cylindrical terminal set. With the help of the lower resolving function for objects with different inertia, two modified schemes of the first direct Pontryagin method are proposed, which guarantee the successful completion of the conflict-controlled process in the class of countercontrols. The upper resolving function is introduced and the corresponding modified schemes of the method of resolving functions for controlled objects with different inertia in the class of quasi-strategies and counter-controls are presented. New theoretical results are illustrated by a model example. Keywords: controlled objects with different inertia, quasilinear differential game, multi-valued mapping, measurable selector, stroboscopic strategy, resolving function.

An approach to the formulation and solution of the problem of optimal selection of quality indicators for products, taking into account the interests of both the producer and the consumer, is proposed. The problem is formulated in terms of mathematical programming. The optimization criterion is the maximum closeness between the attractiveness level of the product and the desire to purchase it; the controlled variables are the levels of indicators specific to the manufacturer and the consumer; the constraints are agreements regarding the necessary levels of indicators shared by both the manufacturer and the consumer. Fuzzy cognitive maps are used to construct the dependencies that appear in the objective function, and optimal solutions are found using a genetic algorithm. The approach is illustrated by the example of a robotic vacuum cleaner, which is one of the best-selling household applications of artificial intelligence. Keywords: product quality, quality parameters, producer, consumer, optimization, fuzzy cognitive map, genetic algorithm, robotic vacuum cleaner.

Pervaporation Of Water From Solvent Solutions
Authors:   , Manning Richard ,   Cork Institute of Technology
Published: July 2024

"Pervaporation is an emerging membrane technology which has found acceptance as a method for the dehydration of organic solvents. An existing pervaporation apparatus was modified to accommodate a new type of pervaporation membrane. The instrumentation used with the pervaporation apparatus was upgraded to include a Keithley Data Logger. A HAZOP was carried out on the modified pervaporation apparatus to ensure the apparatus was safe to operate after the modifications were completed. The pervaporation apparatus was initially tested using screening experiments to verify that changing the operating parameters produced a measurable response which could be recorded. The pervaporation apparatus was successfully used to dehydrate acetonitrile from a concentration close to its azeotropic concentration (0.16 w/w water), to a final product concentration as low as 0.005 w/w water, using two types of pervaporation membrane, a PERVAP 2210 and an Iludest pervaporation membrane. The Solution - Diffusion Model [1] for pervaporation was then applied at the operating conditions under investigation. It was found that the Solution — Diffusion Model showed its greatest agreement with the experimental data in the medium concentration range (0.05 to 0.1 w/w water in the feed). Above this concentration, the effects of the deviation from equilibrium at the membrane surface dominated, below this concentration, concentration polarisation dominated. The heat transfer aspects of pervaporation were also investigated. It was found that the modified heat transfer coefficient proposed by Rautenbach and Albrecht [2] was strongly influenced by the permeate flux required for its calculation. Inclusion of the modified heat transfer coefficient in the overall energy balance resulted in an improvement to the energy balance of less than 1%, making its inclusion unwarranted."

"Traditionally, the issue of colour constancy has limited the success of colour image segmentation algorithms. Numerous methods exist to achieve colour constancy for different applications. The principal contribution of this thesis is the investigation of a suitable technique for the problem of robust colour based object detection. Appropriate colour models are investigated and analysed in order to assess their ability to enhance the isolation process. Models that possess suitable colour constancy characteristics are chosen for use with image segmentation algorithms. Reviews of existing sur\'eys of image segmentation algorithms are appraised for the emergence of a suitable colour image segmentation technique. Active contour models or snakes surface as being apposite. In particular, statistical snakes or, more fonnally, active region models have been demonstrated to possess desirable characteristics when applied to image segmentation. Specifically, statistical colour snakes have been shown to reduce the effects of colour constancy when a colour model, such as Hue Saturation Value (HSV) and normalised Red Green Blue (rgb) is adopted. It is the colour constancy characteristic of the colour model which dictates the statistical colour snake’s ability to isolate objects robustly under varying illumination conditions. The algorithm’s performance therefore depends on the choice of colour space. The Tint Saturation Luminance (TSL) colour model has been reported as a suitable candidate for achieving colour constancy but has not been used in the context of a statistical colour snake. It is therefore used with statistical colour snakes on single and multiple images to evaluate its suitability as an inbuilt model for the snake. Comparative studies of the above mentioned colour models with statistical colour snakes is then carried out to determine the colour snake with the most robust behaviour in isolating an object of known colour under varying illumination."

Published: July 2024

В статье проведены теоретические исследования инновационной инфраструктуры Национальной инновационной системы. Представлены точки зрения различных ученых на ее организацию. Автором выявлены признаки построения инновационной инфраструктуры, отражающие факт того, что инфраструктура включает в себя недостающие элементы для функционирования какоголибо объекта, которые привлекаются из вне. Исследуя инфраструктурные элементы, в статье отмечено, что они представляют собой определенные услуги, которые необходимы для деятельности организаций. Также, это может быть недостающая продукция для производства, закупаемые на рынке узлы и полуфабрикаты. Инфраструктурное обеспечение включает: финансовое, производственное, технологическое, информационное, инновационное, рыночное, инженерное, транспортное, социальное, кадровое, экспертно-консалтинговое и пр. Все это отражает необходимость наличия инфраструктуры. Исследуя содержание инновационной инфраструктуры, в статье отмечено, что в настоящее время не имеется единого подхода к данному термину. Кроме этого, автором выявлено, что нет точных разделений понятий «инновационная инфраструктура» и «инфраструктура обеспечения инновационной деятельности».

The article presents theoretical studies of the innovation infrastructure of the National Innovation System. The points of view of various scientists on its organization are presented. The author identifies the signs of building an innovative infrastructure, reflecting the fact that the infrastructure includes the missing elements for the functioning of an object that are attracted from outside. Examining the infrastructure elements, the article notes that they represent certain services that are necessary for the activities of organizations. Also, it may be missing products for production, components and semi-finished products purchased on the market. Infrastructure support includes: financial, production, technological, information, innovation, market, engineering, transport, social, personnel, expert consulting, etc. All this reflects the need for infrastructure. Examining the content of the innovation infrastructure, the article notes that there is currently no single approach to this term. In addition, the author revealed that there are no exact divisions between the concepts of "innovation infrastructure" and "infrastructure for ensuring innovation activity".

В статье отражены важность и актуальность трансформации антикризисного управления финансовым сектором предприятия. Подчеркнута особенная важность превентивных мероприятий антикризисного управления компании, и рассмотрены направления по разработке превентивных мероприятий. В статье автор выделил типы и классификацию кризисных явлений организаций. Цель данной статьи - отразить необходимость превентивных мероприятий антикризисного управления в структуре каждой организации. В работе выявлены два вида компаний по отношению к антикризисному явлению. Компании первого типа считают себя выше кризисов, не имеют четкого плана действий в случае их возникновения. Компании второго типа, наоборот, имеют определенный план мероприятий по антикризисному управлению. Для решения данной проблемы была дана инструкция по предотвращению кризисного состояния предприятия.

The article reflects the importance and relevance of the transformation of anti-crisis management of the financial sector of the enterprise. The special importance of preventive measures of anti-crisis management of the company is emphasized, and directions for the development of preventive measures are considered. In the article, the author singled out the types and classification of crisis phenomena in organizations. The purpose of this article is to reflect the need for preventive measures of anti-crisis management in the structure of each organization. The paper identifies two types of companies in relation to the anti-crisis phenomenon. Companies of the first type consider themselves above crises; do not have a clear plan of action in case of their occurrence. Companies of the second type, on the contrary, have a specific plan of measures for anti-crisis management. To solve this problem, instructions were given to prevent the crisis state of the enterprise.
