In this regard, the authors researched the performance of geodetic works at all three stages of construction: breakdown, provision of geometric parameters of constructions, control measurements, and executive surveying. We analysed information on using the latest technologies in construction activities and their subtypes. We paid considerable attention to the implementation of modern technologies and approaches. The authors considered such a solution as a ‘digital double’ of the building, which can update the BIM model with real-time data, improving both the construction process and the decision-making. We proposed digital technologies that make it possible to provide a theoretical basis for modelling, forecasting, and control. Thanks to the suggested approach to creating an electronic version of a digital plan, the need for paper media automatically disappears. Also, the transition to a digital form entails a shift to a new level of graphic accuracy. The key indicators of modern construction are modern design systems, which include spatial design and the creation of virtual models and geo-information systems that provide a rational choice of construction sites, optimisation of design and construction, and effective use of resources. The authors also raised a question regarding the outdated regulatory framework. Unfortunately, the main regulatory framework remained at the level of the 80s of the last century. The national regulatory framework is in a difficult situation; the regulatory documents of the former Soviet Union are outdated. It is necessary to update these documents, but the issue of copyright arises here, whereas creating a new regulatory framework requires resources and time. Therefore, it is impossible to utilise all the resources of the measuring equipment. As a result of the research, the authors proposed new approaches to monitoring construction accuracy and creating an electronic version of the tablet during geodetic surveying. The article’s relevance lies in implementing technological progress with the help of digitisation of the entire construction life cycle.\u0000Keywords: construction, architecture, vector graphics, geoinformation systems, geodetic technologies, digital construction technologies.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"36 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140736694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common quality indicator is fire extinguishing time. For fire extinguishing systems focused on extinguishing Class B fires using sprayed water, the authors have constructed a transcendental equation, the root of which is the fire extinguishing time. We derived the equation provided that the intensity of the sprayed water supply to the combustion centre to be described by the Heaviside function. The dynamic properties of fire are defined using the integral Laplace transform. We obtained the functional dependence of class B fire extinguishing time on fire parameters and showed that this time does not exceed a tenth of the constant fire time. In the first approximation, the inertial properties of the fire extinguishing system can be taken into account by the transfer function of an aperiodic link with a generalised time constant. For this case, we constructed a transcendental equation that determines the fire extinguishing time by the inertial fire extinguishing system. We note that, according to inertial properties, fire extinguishing systems fall into three classes. For each of the three classes, estimates of the extinguishing time of a class B fire were obtained, depending on the dynamic properties of this fire. The results show that this time can change several times. The authors have introduced the criterion for the efficiency of fire extinguishing systems, which characterises the degree of approximation of the speed of the fire extinguishing system to the maximum possible value. This criterion also indicates how much it is necessary to increase the extinguishing agent mass supplied per unit area of the fire relative to the extinguishing agent mass supplied in leaps per unit area of the fire, provided that the extinguishing times are the same. We obtained estimates of the effectiveness of fire extinguishing systems using this criterion. Furthermore, we provided recommendations on the use of the efficiency criterion.\u0000Keywords: fire extinguishing system, extinguishing time, efficiency criterion.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"26 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140739019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such engineering-geological conditions significantly impact the choice of foundation structures and the justification of measures to reduce or eliminate the negative effect on the environment and the development of dangerous geological processes and phenomena. We thoroughly studied the deformation and strength properties of the supporting soil layers and developed recommendations for their engineering preparation and improvement of the indicators. Bulk soil is present in local depressions: construction debris, sand, and compacted loam. Based on the analysis of physical and mechanical properties, we could conclude that this soil cannot be used as a soil base for the foundations of buildings due to its loose composition and enrichment with organic substances and must be completely replaced during the production of earthworks. They can be used as a basis for laying engineering networks.\u0000After excavation pits for individual columns, before setting up the preparation, it is necessary to carefully inspect the soil foundation to ensure that it is the same engineering and geological element specified in the project.\u0000The soil base of the foundations is redeposited subsidence loess loams, which have mostly lost their subsidence properties, but local inclusions with subsidence properties have remained in the thickness of these soils. If there are lenses of soils in the soil base with indicators of physical and mechanical characteristics that are lower than those adopted in the project and that have a thickness of less than one meter, they should be removed and replaced with sand or sand-crushed soil with layer-by-layer compaction and compaction quality control. Doing so will create the same soil conditions for the building foundation.\u0000The performed scientific and technical support of the construction made it possible to choose a method of technical soil reclamation—partial replacement of weak soils with sand and crushed stone, which, after layer-by-layer compaction, can withstand a significant load and stability under vibrational influences.\u0000Keywords: landfills, solid household waste.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"6 s1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140737185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thanks to the constant development of algorithms and hardware, neural networks are becoming more and more powerful and efficient, which opens up new opportunities for their application. The authors describe the principle of operation of liquid neural networks, which includes the process of learning and inference, which allows effective use of the natural dynamics of the system to solve various tasks, including classification, prediction, and control. We note that the concept of LNNs arose as an attempt to overcome some of the limitations and problems faced by traditional neural networks. The study considers the basic concepts and principles of LNNs and their application potential in various fields, from robotics to medicine and industry. The study also determines the main advantages and disadvantages of LNNs compared to traditional models. It is possible to use them to process a large stream of data, such as video, audio, or sensory data from various sensor types, allowing robots to receive information about their environment and make decisions based on that data. In medical diagnostics and image processing, liquid neural networks can significantly contribute to the quality and efficiency of diagnostic procedures. LNNs can enable the implementation of automatic control systems that monitor and regulate parameters of production processes or adapt to changes in the environment and optimise parameters to achieve maximum productivity and product quality. The field of LNN lacks standards and is limited to using performance metrics. Establishing standards and objective metrics will allow researchers and engineers to understand and compare different LNN implementations. Although LNNs are relatively efficient in terms of power consumption, their implementation at the hardware level may require new technologies and architectures to optimise performance. As a result, the study outlines the prospects for the further development of this technology.\u0000Keywords: liquid neural networks, artificial intelligence, adaptive control, learning efficiency, application potential.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"10 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140738513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first option has the reliability of the fire inspection, which is equal to one, and the second option has the reliability of the fire inspection, which is different from one. Using graphs of the states of the hydrogen storage and supply system, we constructed systems of Kolmogorov equations and derived expressions for the probabilities of finding this system in the corresponding states.

The authors consider the importance of harmonising national valuation standards with international ones, which will be an essential step toward ensuring transparency, fairness, and efficiency in the land market. The focus is on the impact of internationally recognised standards such as IVS, RICS, and TEGoVA on the land pricing process in different countries. The article discusses in detail the mechanisms through which standardised evaluation methods contribute to increasing the investment attractiveness of land resources, strengthening the confidence of investors and land owners, and improving the legal and economic basis of the land market. The authors emphasise that an adequate assessment of the land that meets international standards is critical for ensuring effective management of land resources, conducting sustainable land use, and preserving the ecological balance. The study reveals the potential advantages and challenges of adopting international assessment standards in Ukraine. In particular, we consider the issues of the need for retraining appraisers, the adaptation of national legislation and regulatory framework, and the potential for increasing transparency and stabilisation of the land market. The article points out the importance of international cooperation and exchange of experience for the successful integration of Ukraine into global market relations, boosting its investment attractiveness and fostering the sustainable development of land resources.

It allowed us to formulate the purpose of the study in this development. This topic is relevant since the efficient organisation of containerised supply logistics can improve the functioning of transport systems. An effective way to reduce the cost of supplying a cargo unit is efficient resource use (railway stations, ports, warehouses, wagons, vehicles, containers). The study paid considerable attention to developing the relevant infrastructure, solving specific problems of efficient use of all types of resources, using digital technologies, and building reliable models of logistics supply systems. The article builds a structural model based on the principles of logistics interaction of possible participants in the supply process, representing the interaction of subsystems that significantly affect the quality of the relevant operations. We formed five schemes of interaction between logistics participants for supplying specialised vehicles in containers with the participation of automobile, railway, and sea transport and the relevant infrastructure. These schemes identify the main ports of departure in the United States (New York and Houston) and ports of destination in Europe (Klaipeda (Lithuania), Constanta (Romania)), and take into account the possibility of using road and rail transport resources in European countries and Ukraine. We developed a mathematical model of logistics functioning for the supply of specialised vehicles in containers from North American enterprises to Ukraine, which accounts for the specifics of sequential operations and the peculiarities of determining the performance indicators of each supply chain operation. The prospect of using these models is to build a simulation model of logistics for the supply of specialised vehicles in containers from North American companies to Ukraine, conduct simulations using a software environment, and determine the rational option under the established conditions.\u0000Keywords: model, logistics, supply, vehicles, international transportation.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"15 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140737223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
