Database Construction and Application of Large-scale Geospatial Data

Abstract. Geospatial data refers to data that related to spatial location. It is the abstract representation of objects, events, or other characteristic information located on or near the surface of the Earth. It characterizes attribute features, spatial features, and associated information of geospatial features. Geospatial data commonly include various data types such as point, polyline, polygon, and so on. Geospatial database is the basic method to store and manage geospatial data. It is also the important component of geographic information systems (GIS). Geospatial database generally stores data in a specific structure in a medium, which can achieve efficient management of geospatial data. Users can add, modify, and delete data efficiently. Furthermore, query retrieval and statistical analysis can be quickly performed based on geospatial database. In this paper, distributed geospatial database is constructed by using database partition tables storage technology. Meanwhile, database construction software is developed to achieve the construction, management, and application of large-scale geospatial data. It can improve data import, query and retrieval efficiency significantly. The database application service system can directly connect to the database for displaying statistical analysis results. At the same time, geospatial data are processed to vector tiles, which stored in the tile database. Furthermore, standard online service is then published, which can be used for database management and application service system. It can be used for natural resource management work such as basic surveying, survey and monitoring, and so on.

Multi-channel photonic sampled ADC with hybrid deep-learning for distortion recovery

Analog-to-digital converter (ADC) is indispensable components in modern information systems, and photonic technologies have emerged as promising avenues for overcoming bottlenecks in ADC performance. This paper introduces a novel approach: a photonic sampled ADC integrated with a neural network that combines Convolutional Neural Networks (CNNs) and Transformers for data recovery. The proposed system utilizes a multi-wavelength optical sampling pulse train interleaved in the time domain through fiber dispersion. Sampled signals are quantified in parallel channels by electronic ADC (EADC). Through supervised training, the hybrid deep neural network extracts both local and global features of photonic system defects, enabling the recovery of distorted data. Experimental validation showcases the effectiveness of this architecture, achieving successful reconstruction of radio frequency (RF) signals at a sampling rate of 12 Giga-samples per second (Gs/s) with an effective number of bits (ENOB) of 7.13. The results underscore the potential of the proposed architecture in achieving high conversion accuracy in multi-channel photonic sampled ADCs.

ВИКОРИСТАННЯ ЕЛЕКТРОННИХ СИСТЕМ ДОКУМЕНТООБІГУ ТА ЗВІТНОСТІ ЛОГІСТИЧНИМИ КОМПАНІЯМИ УКРАЇНИ

The article explores the possibilities and ways of using information technologies for document management and electronic reporting at logistics enterprises. Theoretical approaches to understanding the goals and tasks of logistics information systems in transport technologies have been considered. The main information technology systems that change the logistics industry in modern conditions have been characterized, namely: RPA; chat bots; visualization; Artificial Intelligence; predictive analytics. The electronic technologies used for information provision in Ukrainian practice, the IT-Enterprise ERP system of JSC ‘Ukrposhta’ and the CRM system of the company ‘Epicentr K’ have been analyzed. Their characteristics and advantages of use have been defined. It have been found that the basis of the functional component of the modern information system is a single module of operations between the links of the logistics system, which determines the relationship between the functional divisions of the company (in terms of the implementation of logistics functions), intermediate links and consumers of the company’s products. The implementation of a logistics information system in the work of a logistics enterprise makes it possible: - to increase the efficiency of its work, achieve a high level of service for customers and ensure effective control; - to ensure a modern approach to the management of implementation processes and the organization of various types of events; - to monitor the efficiency of commercial operations; - to conduct an analysis of the profitability of the activity; - to increase the effectiveness of price policy, etc. The problems of the introduction of electronic document flow and reporting systems in Ukraine have been noted: - the problem of interoperability in electronic document flow; - lack of clear standards and requirements for electronic reporting, companies may hesitate to switch to this type of reporting; – constant changes in legislation and requirements can create difficulties for enterprises in implementing stable electronic reporting systems; - inconsistency of electronic reporting formats with global ones; high implementation costs; - concerns about data privacy and security can deter companies from switching to electronic reporting, especially when the security of information on the network is at stake.

Electronic nanolithography as a basic nanoavionics technology

The need for further development of electronic components of aviation and rocket-space information and commu-nication systems towards nanoelectronics brings nanolithography to the forefront as its basic technology. A promis-ing nanolithography method is electron nanolithography (ENL). Advantages of ENL: 1) potential resolution - less than 2 nm, 2) possibility of direct recording without the use of masks, 3) possibility of using standard film resistors, 4) low density of defects in circuits, 5) controllability using electric and magnetic fields, 6) possibility use of ready-made industrial installations (microscopes, lithographs for masks). This review examines the principles of con-struction, the history of creation and the current state of ENL, with an emphasis on its features, as well as its classi-fication and stages of development. In addition, one of the main problems of ENL that requires a solution is con-sidered – the development of special electronic resists and methods for increasing their resolution and sensitivity.

Information model for assessing the impact of tactical material procurement risks on order fulfillment in make-to-order manufacturing

Manufacturing businesses are showing increased interest in the issue of supply risks for materials and components. In recent decades, numerous studies and reviews have been published on the subject of supply chain risks. However, most research examines the global impact of risks on business as a whole and proposes a multi-level procedure for identifying, assessing, and developing risk mitigation measures, which should be carried out in advance with the involvement of specialists and experts. Nevertheless in maketo-order manufacturing, it is important to assess the risks of material supply for individual production orders, at the same time taking into account constant changes in production state and supply chains. The problem of assessing the risks of material supply gets even more complicated at enterprises with a high mix of manufactured products. To solve the above-mentioned problems, the authors propose an automated model for risks evaluation. The model is implemented as a component of the enterprise's information system (ERP) and uses data from the technological, production, inventory, and logistics modules to calculate the probability of deviation in order fulfillment time from the planned schedule due to potential disruptions in material supply chains. When executing the model, it analyzes the production's material requirements in both volumetric and calendar terms, inventory levels, and the condition of supply channels. The risks of delayed delivery for each material are expressed as the standard deviation of the delivery date from the planned date and are calculated by composing the risks for segments (elements) of the supply chain, the risks for which are, in turn, calculated based on performance data accumulated in the logistics module, with the possibility of introducing correction coefficients and expert evaluations. The overall risk of order material supply is determined by summing up the delivery risks of individual materials, expressed as the corresponding standard deviations. The model's results can be used for managerial decision-making in production and procurement or for communicating expected order fulfillment times to customers. The model has been tested at an enterprise in the electrical engineering industry.

Management Information Systems for Tree Fruit–2: Design of a Mango Harvest Forecast Engine

Spatially enabled yield forecasting is a key component of farm Management Information Systems (MISs) for broadacre grain production, enabling management decisions such as variable rate fertilization. However, such a capability has been lacking for soft (fleshy)-tree-fruit harvest load, with relevant tools for automated assessment having been developed only recently. Such tools include improved estimates of the heat units required for fruit maturation and in-field machine vision for flower and fruit count and fruit sizing. Feedback on the need for and issues in forecasting were documented. A mango ‘harvest forecast engine’ was designed for the forecasting of harvest timing and fruit load, to aid harvest management. Inputs include 15 min interval temperature data per orchard block, weekly manual or machine-vision-derived estimates of flowering, and preharvest manual or machine-vision-derived estimates of fruit load on an orchard block level across the farm. Outputs include predicted optimal harvest time and fruit load, on a per block and per week basis, to inform harvest scheduling. Use cases are provided, including forecast of the order of harvest of blocks within the orchard, management of harvest windows to match harvesting resources such as staff availability, and within block spatial allocation of resources, such as adequate placement of harvest field bin and frost fans. Design requirements for an effective harvest MIS software artefact incorporating the forecast engine are documented, including an integrated database supporting spatial query, data analysis, processing and mapping, an integrated geospatial database for managing of large spatial–temporal datasets, and use of dynamic web map services to enable rapid visualization of large datasets.

Machine Learning System Development in Information Systems Development Praxis

Advancements in hardware and software have propelled machine learning (ML) solutions to become vital components of numerous information systems. This calls for research on the integration and evaluation of ML development practices within software companies. To investigate these issues, we conducted expert interviews with software and ML professionals. We structured the interviews around information systems development (ISD) models, which serve as conceptual frameworks that guide stakeholders throughout software projects. Using practice theory, we analyzed how software professionals perceive ML development within the context of ISD models and identified themes that characterize the transformative impact of ML development on these conceptual models. Our findings show that developer-driven conceptual models, such as DevOps and MLOps, have been embraced as common frameworks for developers and management to understand and guide the ML development processes. We observed ongoing shifts in predefined developer roles, wherein developers are increasingly adopting ML techniques and tools in their professional work. Overall, our findings underscore that ML technologies are becoming increasingly prominent in software projects across industries, and that the incorporation of ML development in ISD models is an ongoing, largely practice-driven, process.

Conceptualizing the Integration of Business and Private Components in Individual Information Systems

AbstractIndividuals build their individual information system (IIS) with which they manage the boundary between different domains of life. In this age of permanent mobile accessibility, however, the boundary between the private and business domains can become blurred. While some users try to maintain a degree of separation between the two IIS sub-systems (the private and the business information system), others integrate them. Understanding such integration is essential as it affects well-being and performance in both domains. To further this understanding, we introduce a conceptualization of IIS that distinguishes between four layers of IIS: devices, digital identities, relationships, and information. To measure IIS integration, we develop a method based on the IIS components’ usage frequencies in each domain. We evaluate our conceptualization as well as our measurement method by empirically testing a theoretical model of IIS integration on multiple layers. Our data provides empirical support for the importance of relationship integration as one of the four layers. This leads us to the conclusion that even though IIS are composed of four layers, only the relationship layer is of interest regarding IIS integration. Our results are of interest and service to individuals, organizations, and IT designers who aim to manage IIS integration for individual and organizational benefits.

Agro-Tourism Development in Cambodia: A Literature Review

Agro-tourism, sometimes referred to as eco-tourism or rural tourism, has gained international acceptance as one of the primary methods for establishing rural sustainability. In this definition, agro-tourism refers to the fusion of agricultural, ecological, and cultural products for a variety of purposes, such as social, educational, recreational, health, and environmental. The agriculture industry is the main driver of the Cambodian economy, and in order to sustain the livelihoods and economics of the people living there, a number of tourism-related companies must expand. Finding the most crucial development methods for Cambodia's agro-tourism sector is the primary objective of this review. Aspects of political stability, the development of rural community infrastructure, strategy plans, tourist product stability, marketing components, information system components, encouraging local tourism, investment appeal, and financial support are among the main essential considerations. Strategies are essential to expeditiously enhancing the agro-tourist activities delineated in government policies, including those pertaining to the agricultural sector, agricultural communities, and nature, culture, and society-related tourism. The review has revealed that a wide range of factors could greatly aid in the adoption of agro-tourism development plans and methodologies throughout Cambodia's diverse ecological zones.

A quantitative fuzzy-valued intersection matrix for obtaining fuzzy relationships between vague spatial objects

Topological relation between geographical objects is one of the key components of the Geographical Information System (GIS). Considering the objects to be exact with sharp boundaries, four intersection, and nine intersection matrices initiated the study of calculating the topological relations. Due to the extensive existence of vague spatial phenomenons, the study of uncertainty object modeling has grown rapidly. Parallelly, the relationship calculating tools have been upgraded to handle vague concepts. The fuzzy 9-intersection matrix and Egg-Yolk methods are popular tools. Although the geographical objects are uncertain, surprisingly, most of these tools generate certain relations between them. The qualitative nature of these tools overlooks the essence of their uncertainty. We propose a quantitative fuzzy-valued 9-intersection matrix to overcome these drawbacks to obtain a fuzzy relationship between uncertain geographical objects. Then two new similarity computation techniques are introduced to calculate the membership grade between the proposed matrix and the known crisp matrices. These similarity computations allow two spatial objects to have partial membership against the eight established topological relations. The quantitative calculations indicate the strength of the relationship. The superiority of the proposed model is exhibited through comparative studies. Further, certain linguistic variables are linked to the evaluated membership grades to generate an immediate association with the known crisp relations. Examples are provided to demonstrate the applicability and efficacy of this association.

Повышение производительности и отказоустойчивости схемотехнических САПР на основе методов диакоптики и автоматизации управления мультитенатными компонентами

An approach to building automated control of multi-tenant components of information systems is described. The main advantages of using discretizing multi-tenant shells for building distributed information systems are reflected and justified. Methods for managing the infrastructure of a distributed system as a code are given. Technologies and their settings for automating management at different stages of the life cycle of a software system built on the basis of discretizing multi-tenant shells are presented. The solution to the problem of dual use of the process manager in a container based on the Linux operating system in a manual and automated version in the context of managing life cycle stages using the CI / CD approach is described. A technique for modeling weakly coupled electronic circuits based on the technology of calculating large electronic circuits in parts is proposed, by selecting weakly coupled subcircuits between which there are no inductive connections and the condition for the concentration of control and controlled variable dependent sources within a separate subcircuit is met. It is shown that the implementation of the diacoptic approach to modeling large loosely coupled circuits significantly increases the productivity of the computational process, which is especially important in the development of distributed computer-aided design systems. It is proposed to build and transform the description of the simulated circuit to use generalized signal graphs that display the equations of the circuit in a generalized cause-and-effect form.
