This paper presents a new virtual reality (VR)-based approach to advanced learnings and experiences of the circular economy (CE) in the construction industry. The approach involves incorporating game design and a building information modelling (BIM) digital twin of a purposed CE prototype building. Our novel approach introduces VR environments designed to provide a visual representation of materials and components that can be reintroduced into the supply chain at the end of life and their removal procedures and material provenance. A case study methodology was applied to a purposely designed CE building, namely the Legacy Living Lab (L3). To reflect the real-life building, L3’s BIM model was combined with Unify game software to advance the literature in three key areas. First, the research investigates VR tools that will allow building designers to view and implement their strategies to advance CE design. Second, this research proposes an advanced VR tool to visualise the bill of quantities (BoQ) and material stock embedded in the studied building, further understanding concepts such as buildings as material banks. Finally, the proposed VR environment defines CE techniques implemented within the case study to be disseminated across the vast construction industry. This VR research identifies three key pillars in reducing the waste generated by the construction industry: education, documentation and visualisation. Furthermore, this paper provides a visual link between the BIM, BoQ and resiliency of the selected materials.

Abstract Potato has an important role in human food. It was the sixth alimentary product in the world after sugar cane, maze, rice, wheat and milk in 2011 year. In addition, potato is the third product in Iran after wheat and sugar cane in 2011 year. Therefore, any attempt in the improvement of potato harvester will be valuable. In this study, a new semi-mounted one-row potato digger with rotary blade was designed and made in the workshop of Shahrekord University. It can be connected to rotary potato graders. Transmission system was mechanical from tractor (PTO) to blade by belt, pulley, gearbox, chain and sprocket. Blade diameter was 76 cm and the length was 10 cm which was assigned by the researchers. For separating of soil from potato, a helix containing bars with 2.6 cm distance and diameter of 9 mm was applied. Entered soil into set was calculated as 227 ton/h. Required power was got 5.5 horsepower. Computerized model of set was prepared in Mechanical Desktop Software and potato motion was studied in Visual Nastran Software. The device was tested at field with various advance speed, blade angle and rotational speed. Results showed that advance speed of 1.5-3 km/h, rotational speed of 20-25 RPM and blade angle of 10- 15° were proper for system. The average of damaged potatoes was 4%.

Quickly estimating the main engineering quantity and project cost of the project is conducive to the management staff to have an overall grasp of the project in the early stage and to grasp the development direction of the project in advance. Moreover, it can play an important guiding role in the further construction management of the project and can help managers prevent the emergence of unfavorable factors in the project, make corresponding construction deployments, and avoid risks. This paper combines artificial intelligence technology to construct a construction project cost simulation system. In this system, BIM is mainly used to simulate construction engineering, and the construction engineering cost is simulated and analyzed in combination with the pricing file. Finally, the results of experimental research show that the intelligent model proposed in this paper can play an important role in the cost of construction projects.

Full textAbstract:
Building Information Modeling (BIM) has been increasingly used in coordinating the different mechanical, electrical, and plumbing (MEP) services in the construction industries. As the construction industries are slowly adapting to BIM, the use of 2D software may become obsolete in the future as MEP services are technically more complicated to coordinate, due to respective services’ codes of practice to follow and limit ceiling height. The 3D MEP designs are easy to visualize before installing the respective MEP services on the construction site to prevent delay in the construction process. The aid of current advanced technology has brought BIM to the next level to reduce manual work through automation. Combining both innovative technology and suitable management methods not only improves the workflow in design coordination, but also decreases conflict on the construction site and lowers labor costs. Therefore, this paper tries to explore possible advance technology in BIM and management strategies that could help MEP services to increase productivity, accuracy, and efficiency with a lower cost of finalizing the design of the building. This will assist the contractors to complete construction works before the targeted schedule and meet the client’s expectations.

Full textAbstract:
The construction method of transitioning from a small cross-section to excavating a super-large cross-section tunnel plays a crucial role in the quality of the final super-large cross-section tunnel and the safety of the tunnel structures and workers during the construction process. The Shenzhen Liantang Bifurcated Tunnel, with a maximum cross-sectional area of 428.4 m2, was the largest cross-sectional tunnel constructed in China in 2018, and there are few engineering projects that can serve as references. To enhance construction safety and achieve the transformation from a two-lane tunnel to a five-lane tunnel, this paper proposes two tunneling methods, namely, the reverse top-heading method and the advance climbing method. Moreover, numerical simulation using MIDAS GTS/NX software was adapted to compare and analyze the stress and deformation characteristics of the surrounding rock in the construction stages using the two methods. The simulation shows that the advance climbing method is more suitable for the construction of the Liantang tunnel. Through on-site monitoring and measurement, the data of peripheral rock vault subsidence, peripheral convergence, and pressure of the supporting structure were assessed. The results show that the maximum values of peripheral rock vault subsidence and peripheral convergence displacement are located in the permissible range of road tunnel vault subsidence. This further verifies the reasonableness of the advance climbing method. This paper not only provide a basis for the construction of the Liantang tunnel but also serves as a reference for construction methods and typical cases for similar super-large-section tunnel projects.

Based on the PBA construction method of Changchun Liberation Road station metro line No.2, in order to get the optimization of construction sequence of six pilot tunnels, we use numerical simulation method and finite element software MIDAS GTS to establish the construction model of the station pilot tunnel. After comparing four excavation methods of the surface subsidence, we come to a conclusion that first up then down and first side then middle is the optimal excavation scheme. At the same time, we make models to analysis the necessity of making advance support before pilot tunnel construction. Pipe shed and small duct grouting pre support is very significant to the control of the subsidence of ground surface and vault.

Large software conglomerates like Trimble and Autodesk provide consumers with suites of software that perform many functions within the design and construction process. Communicating with software outside of the suite can be highly problematic as file types and communication protocols are proprietary and closed within that software family - the antithesis of interoperability). This is in stark contrast with emerging trends in consumer computing, where we find a rich ecosystem of devices and services facilitating a period of intense innovation. This paper documents original research that aims to implement communication beyond specific software suites and test, to what extent, wider software ecosystems revolving around open standards might be implemented within the design and construction domain. Our first test case—an agent-based dynamic simulation combining natural and built environmental components—is deployed to explore the city as a multitude of interrelated natural and built patterns. We analyze the role this simulation might play in managing the complexities of rebuilding a sustainable urban environment after the devastating earthquake in Christchurch, New Zealand. The second test case deploys an iPad application to communicate with a BIM model - exploring the development of a mobile application and methodology for openly communicating outside of the intended software family. Through these case studies we begin to identify ways to leverage emergent device and data ecosystems and representations for ‘knitting' devices and services together in innovative ways to advance design and construction processes.

The prediction of ground collapse caused by subway shield construction has been an important technical problem in urban subway shield construction, if the ground collapse could be pre-estimated, it could be able to take appropriate precautionary measures in advance to avoid the occurrence of ground surface settlement before the project construction, but it’s difficult to predict and calculate the settlement accurately. This paper analyzed main causes of ground collapse caused by shield construction, summarized the influence of several important parameters to surface settlement and then Midas GTS 3D numerical simulation software was used to simulate shield construction process and calculate ground surface settlement, to calculate stress, strain and displacement of overlying strata above the shield driving machine, obtained calculated values of surface settlement to predict ground collapse. Practice has proved that this pre-estimation new technology is in accordance with fact, it provides a useful reference for subway shield construction project.

With the rapid development of urbanization, the speed of constructing urban underground space and ground foundation engineering is accelerated. With the shortage of land resources, the distance between underground engineering and surface engineering is getting closer and closer, and the contradictions and problems between projects are becoming more and more serious. Based on the new subway station, this paper passes the existing urban viaduct in a short distance. The settlement and deformation of pile foundation and buildings caused by the excavation of the subway station is studied by using ROCSCIENCE software and site monitoring method. The potential risk sources around the station are pile foundations 18.5 m away, residential buildings 15 m away, storm water pipes 7.3 m away, and high-pressure gas pipes at 5.6 m. According to the construction requirements of pile foundation settlement deformation during metro station excavation, we set up construction standards. The settlement of the buildings and pipelines around the metro station should not exceed 3 mm, and the horizontal displacement should not exceed 2 mm. The diaphragm wall is adopted to surround the subway station, and the ground is reinforced by advanced grouting. The results show that, during the excavation of the foundation pit of the metro station, the ground and the building will have obvious settlement deformation and the depth of deformation can reach 9 mm, which is more than the allowable value. The settlement deformation of the ground and the surrounding buildings can be controlled within 3 mm by strengthening the foundation pit support and ground advance-grouting reinforcement. The control of construction deformation can meet the construction requirements.

Abstract. The paper investigates the advance in the most intimate understanding of the construction methods of the Fabrica Solimene (1952–1955) in Vietri sul Mare, (Campania-Italy). The aim is to increase the level of geometric and informative detail of the model, digitally (re)built by means of an indirect method using a total station survey and subsequently by means of a direct method, i.e., by importing the elaborations derived from laser scanner acquisitions and photographic data sets into a BIM authoring vector software. For this purpose, using photogrammetry, new details are acquired, specifically addressed to the study of the static-mechanical behaviour of the perimeter wall studied in its mathematical configuration of the projecting bodies from bottom to top. This study is organised on the elaboration of new clean and decimated point cloud acquisitions to be converted into volumetric models for direct use in finite element calculation (FEM) codes aimed at structural analysis. Thanks to the proposed procedure, it possible to maintain the level of geometric detail appropriate to the resolution required for the analysis. At the same time, it makes it possible to find the best pipeline to reduce the size of the model and obtain the most accurate static-structural results.

Introduction. The problem of automated testing in the process of designing construction facilities has been solved at the international level for more than 40 years. Earlier articles had overviews of design verification systems, presented in the form of information models (IM) of construction projects. However, over the last few years the process of digitalization of the construction industry has become more intense, and new countries, including Russia, have been more actively involved in it. Hence, new methodological approaches to individual stages of verification, programmes and systems, not described in earlier reviews, have appeared. At the same time, many previously developed systems have been modified or, conversely, have ceased to exist. The purpose of this article is to evaluate the current state of IM verification systems for construction projects, taking into account the changes that have taken place over the last few years, and to determine the prospects for their further development. Materials and methods. To determine the current state of systems for testing the IM of construction facilities, the co-authors selected and analyzed the foreign and Russian literature and information sources in the field of testing the IM of construction facilities. The results of earlier reviews were also taken as the benchmark. Results. The co-authors made a list of currently used replicable commercial solutions for information model testing, which are classified according to their designation and a per-country list of information model testing systems, with the status identified for each system. The co-authors identified the development areas in respect of verifying international models of construction projects of international scale. Development areas in the field of verification of informational models of construction facilities at the Russian Federation level were also outlined. Conclusions. Presently, there is still a problem of converting regulatory requirements into the machine-readable format to ensure their compliance with Russian and international standards. Therefore, the main direction for the further development is the study the potential of artificial intelligence in the processing of regulatory requirements written in a natural language. Nevertheless, the application of neural networks requires the availability of data for training, which suggests the need for a certain amount of manually marked regulatory documents in advance.

Some of the serious space weather consequences, for instance, include interruption of space communication and navigation, compromising the safety of astronauts and satellites, and damaging power grids. Therefore, the solar activity research has both scientific and social impacts. The major database is built up from digitized and standardized film data obtained by several observatories around the world and covers a timespan more than 100 years. After careful calibration, we will develop feature extraction and data mining tools and provide them together with the comprehensive database for the astronomical community. Our final goal is to address several physical issues: filament behavior in solar cycles, abnormal behavior of solar cycle 24, large-scale solar eruptions, and sympathetic remote brightenings. Significant progresses are expected in data mining algorithms and software development, which will benefit the scientific analysis and eventually advance our understanding of solar cycles.

The automatic construction of knowledge graphs (KGs) from multiple data sources has received increasing attention. The automatic construction process inevitably brings considerable noise, especially in the construction of KGs from unstructured text. The noise in a KG can be divided into two categories: factual noise and low-quality noise. Factual noise refers to plausible triples that meet the requirements of ontology constraints. For example, the plausible triple <New_York, IsCapitalOf, America> satisfies the constraints that the head entity “New_York” is a city and the tail entity “America” belongs to a country. Low-quality noise denotes the obvious errors commonly created in information extraction processes. This study focuses on entity type errors. Most existing approaches concentrate on refining an existing KG, assuming that the type information of most entities or the ontology information in the KG is known in advance. However, such methods may not be suitable at the start of a KG's construction. Therefore, the authors propose an effective framework to eliminate entity type errors. The experimental results demonstrate the effectiveness of the proposed method.

Construction projects were massively disrupted by the Covid 19 pandemic. The pandemic significantly affected how construction activities are carried out on site. This study investigated in depth the challenges construction teams faced while managing the projects amidst the COVID 19 pandemic. The study collected data using a google form questionnaire. The questionnaire was distributed to 52 respondents in total who were actively involved in the management of the construction projects. The collected data was analysed using SPSS software version 26. Findings indicate that the COVID 19 pandemic caused disruption in the management of projects. The construction sites were abandoned by foreign skilled labours and left unskilled local workers on site. Results indicate that it was impossible to work on site because of the imposed restriction measures. Work was done online but proved to be a challenge since one needs to be on site to make decisions about activities. People lost jobs, lives and the local economy was disrupted. Supply chain of construction materials was disrupted because ports and boarders were closed. The study recommends that projects must procure materials in advance, develop a policy of training local labours to transfer skills, encourage local manufacturing and workers to be vaccinated.

Rapid urban development in Morocco has led to increased construction activities and significant environmental concerns. Recently Zenata City has undergone significant urban development, marking a crucial step in its trajectory toward a modern smart city. As a part of this growth, our research incorporates an innovative method within the you only look once version 8 (YOLOv8) model, representing a significant advance over conventional methods. The YOLO algorithm has been updated with new features and improvements that infuse our work with a dash of innovation. YOLOv8 integration improves construction and irregular construction detection accuracy beyond what is possible with traditional applications. We trained our algorithm using orthophoto captured by DJI MATRICE 300 RTK drone split into georeferenced tiles and annotated using LabelImg software. Through this process, we were able to create a solid 742 image dataset for training, testing, and validation purposes related to construction. Utilizing drone imagery and the YOLOv8 object detection algorithm, buildings and construction irregularities are detected with high accuracy after 300 training epochs on Kaggle's GPU P100. Insights for early detection and effective building site management are provided by this all-encompassing strategy, which supports Zenata City's sustainable urban growth.

In a new highway project, the engineer has to plan, design and construct either a net – work of a new road or a road link. There are also projects requiring re-design and re-alignment of existing roads for upgrading the geometric design standards. In most of frequently used methods for earthwork quantity calculation, the valuation of accuracy may contain some uncertainties. This article discusses the relationship between the manual process and digital process data for earthwork calculation and how to easily create a better profile for any road construction for smoothness in driving with safety parameters. The main purpose of this research is to propagate error. In this a formula is formed which expresses the earthwork quantity relationship that how the errors of manual data effects the accuracy of earthwork calculation using the digital approach. By setting the different values of the parameters, we can calculate the relative errors. At last, we have also discussed the calculation of earthwork quantity using the software sources as well as focused on profile of road, cross section, slope and gradient also etc. The work of profile correction and earthwork is the main step in any highway Engineering. So, it is very necessary for any contractor to carry this work with full precautions and complete the work without any errors in the calculation. The highway and road works or the drainage constructions are very important constructions as it shows the economy of a country. It beautifies the surrounding of a place. If the design of road and profile is not done properly then it may lead to many accidents and other major losses can occur. So, it is important for all the road profile designers to design a proper profile by which the vision, sight distance and curve gets clear technically. And with this we have to make sure that the quantity of earthwork according to road condition should be economically suitable. But seeing today’s scenario which is coming up in Advance Technology Construction field, such as heavy machinery equipment which can complete any work in a short time and in a situation, where work need to be completed in short time, it would be very difficult to calculate the quantity in the old way and if the old way is adopted then it will take a lot of time to complete the work so that to get rid of problem and to bring progress and accuracy to work, we get a lot of help from this software.

This article highlights the preparation of finite element models for analysis that is being increasingly automated, with new developments expected to greatly advance the field. The key to an efficient finite-element analysis (FEA) is frequently an effective finite-element mesh. The construction of this mesh is the first step in the analysis process. Structured grids, as is implied by the name, have a clear structure. The techniques used to generate them produce quadrilateral or triangular cells, or elements, in two-dimensional analysis, and tetrahedral or hexahedral elements in three-dimensional simulations. An area of great potential is the automatic adaptation of the mesh, without intervention by the analyst, and automatic continued solution until the required accuracy has been reached. To effectively automate the choice of the mathematical model and its solution, major advances in theoretical issues and software development are still required and will provide an exciting challenge for the years to come.

Due to poor engineering geological conditions of Liujiazhuang tunnel on Shanghai-Kunming Passenger Dedicated Line, the large deformation of weak rock occurs repeatedly during tunnel construction. In this paper, the large-scale finite element software ABAQUS is used to simulate the construction process of a large-section tunnel in weak surrounding rock. It is found that when tunnel face passes through the coal seam, the displacement and stress simulated by the bench method increase abruptly. The maximum stress reaches up to 18 MPa, and displacement reaches 45 mm, which is about twice when without crossing coal seam. It is technically feasible to use the bench method for tunnel construction, under the condition when large settlements is allowed; additionally, the bench method has better technical and economic benefits than that of the CD method. Through the comparative analysis of onsite monitoring data and numerical simulation results, it can be seen that the tunnel is in a dangerous state when passing through the coal seam and measures such as strengthening support or auxiliary advance support should be taken immediately to control the surrounding rock and to ensure tunnel construction safety.

Effective schedule management is a critical factor in the successful execution of high-rise building projects. This paper explores the impact of robust schedule management practices on project performance, highlighting the benefits, challenges, and strategies for optimizing timelines. High-rise construction presents unique complexities, including coordination of multiple trades, strict safety regulations, and logistical challenges related to vertical construction. Utilizing advanced scheduling methodologies such as Critical Chain Project Management (CCPM) and Building Information Modeling (BIM), combined with traditional techniques like the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT), can significantly enhance project efficiency. The integration of these methodologies facilitates better resource allocation, reduces delays, and improves overall project outcomes. The study also addresses the role of technology, including project management software like Primavera P6, in enhancing schedule accuracy and reliability. Additionally, it examines the critical role of project managers in orchestrating these activities and emphasizes the importance of effective communication and risk management. This comprehensive review provides insights into the key factors that contribute to successful schedule management, offering recommendations for future research and practice to further advance the field.

An automated shipbuilding process is capable of increasing productivity and reducing the workforce. However, to set up a new automated workshop in a shipyard requires many years, tremendous costs, and also high risks. During the construction of the new workshop, more advanced but cheaper hardware and software are expected. In addition, the shipbuilding market may also be changed. The new workshop then may lose competitiveness. Therefore, the design of a new workshop and the simulation of product flow at the designed workshop in advance would be of considerable value in the construction of the new workshop facility. The design could save construction time and cost, and reduce risks. This paper describes the design of an automated fabrication workshop for the shipbuilding industry. The workshop considered consists of job shops for the registering of material plates, cutting, rolling, lineheating and loading of products. An automated manufacturing system is developed for the control and simulation of product flow in the workshop by use of recent information technologies, such as object-oriented modeling, networking, simulation methodology, monitoring on the Internet, and database management. Using the developed system, a product-flowsimulation is carried out, in order to evaluate productivity. Productivity is defined herein as the overall performance of the product flow, that is, less waiting time for processing, less idle time for machinery, rapid completion time, and related issues. A layout of the automated fabrication workshop is then suggested.

Abstract It is most likely that at the beginning of the 21st century, with the 4th industrial revolution, we will find ourselves at the borderline between technique and technology. The question underlying this article is whether the technological advance that the construction industry presents today can lead to the full replacement of the technique in the testing laboratories. Decisions on structural systems extracted from these laboratory-made physical models were often accurate, but the cost and time involved made the validation method low-yield. Today, through digitalization, all structural concepts can be directly realized in 3D with software specially designed for the AEC (Architecture, Engineering & Construction) industry. Models made in this way can be developed down to the smallest detail, can be calculated and dimensioned from a structural point of view under different assumptions, and then can be georeferenced and managed from the point of view of assets.

The need for internet of things (IoT) and machine-to-machine communication (MTC) has been growing rapidly all across the world. To meet the client's needs, many literature reviews were undertaken in several countries. Orthogonal frequency division multiplexing (OFDM), Universal Filtered Multi-Carrier (UFMC), filter-bank multicarrier offset construction amplitude modulation (FBMC-OQAM), generalized frequency division multiplexing (GFDM), and others are candidates for LTE, LTE advance, and 5G, according to the majority of the researchers. However, because it is sensitive to propagation and noise, such as amplitude, with a huge dynamic range, it requires RF power amplifiers with a high peak to average power quantitative relationship; consequently, it is not recommended for LTE, LTE advance, or 5G. As a result, the same concerns were addressed by introducing innovative type filtered orthogonal frequency division multiplexing (F- OFDM), which was the subject of this study. In addition, F-OFDM mathematical models were constructed and simulated in the MATLAB software environment. To validate the proposed innovative F-OFDM, OFDM was compared. For innovative F-OFDM, the simulated result was 0.00083333 bit error rate (BER). Furthermore, the bit error rate (BER) of F-OFDM over OFDM was 89.4 percent, and the peak to average power ratio was 17 percent. The simulation results unmistakably show that the suggested innovative F-OFDM is the greatest fit for LTE, LTE advanced, and 5G contenders.

Digitisation in the construction industry continues to advance and, together with the increasing dissemination and further development of hardware and software, is steadily opening up further opportunities for innovative ways of working. Building Information Modelling (BIM) is currently becoming the standard for new construction but has not yet been optimised for use in existing buildings. Therefore, the Institute of Building Materials Research (ibac) is researching new methods and possibilities for BIM-based building preservation. In this paper, the automated creation and analysis of point clouds as well as the implementation of further information from in situ diagnosis and monitoring systems in BIM-Models are presented. On a practical example, the different steps of a subsequent digitisation of an existing building are demonstrated considering new possibilities as autonomous robots and the intelligent utilisation of sensors and diagnostics tools. The goal is a decision support tool, which is independent from proprietary software, adaptive to different types of buildings and open for various interfaces. Current results show that quantifying point clouds and making BIM-models usable beyond the planning and execution phase for new buildings are essential steps for the digitisation of building maintenance. The proposed digital workflow holds great potential for effective building diagnoses and efficient service life management.

Cranioplasty aims to reconstruct skull defects from tumours, congenital anomalies, decompressive craniectomies, and fractures in a cosmetically acceptable manner. Since the 1970s, polymethyl methacrylate (PMMA) prostheses have been manually prefabricated using a variety of techniques. However, more recent computer-aided design and computer-aided manufacturing (CAD/CAM) techniques appear to have eclipsed these older methods. These techniques essentially involve using imaging from the patient's cranial defect and prefabricating the PMMA prosthesis using a 3D printer. The traditional methods for producing prostheses require a number of intricate stages, can be extremely stressful for the patient, and their success depends on the expertise of the maxillofacial team. Although there have been advances in digital fabrication for prosthetics, there are still some constraints that prevent a full transition to digital fabrication for the final stages of prosthesis construction. Advance training and modification of current treatment procedures are required due to the introduction of new technologies and methods in the field of maxillofacial prosthodontics. The aim of this study is to compare and evaluate the accuracy of cranial prosthesis designed by conventional, digital and two hybrid workflows We will report on 10 consecutive patients who have undergone cranioplasty surgery or had trauma for an extensive skull defect. The final prosthesis will be analyzed using the software CloudCompare for its accuracy by using reverse engineering principle. The purpose of this research is to develop a hybrid protocol for fabricating a prosthesis that is both cost-effective and more dimensionally accurate than its conventional counterpart, thereby providing ease for both the patient and the maxillofacial team.

Considering the prevailing rule of Large Language Models (LLMs) applications and the benefits of XML in a compiler context. This manuscript explores the synergistic integration of Large Language Models with XML-based compiler tools and advanced computing technologies. Marking a significant stride toward redefining compiler construction and data representation paradigms. As computing power and internet proliferation advance, XML emerges as a pivotal technology for representing, exchanging, and transforming documents and data. This study builds on the foundational work of Chomsky's Context-Free Grammar (CFG). Recognized for their critical role in compiler construction, to address and mitigate the speed penalties associated with traditional compiler systems and parser generators through the development of an efficient XML parser generator employing compiler techniques. Our research employs a methodical approach to harness the sophisticated capabilities of LLMs, alongside XML technologies. The key is to automate grammar optimization, facilitate natural language processing capabilities, and pioneer advanced parsing algorithms. To demonstrate their effectiveness, we thoroughly run experiments and compare them to other techniques. This way, we call attention to the efficiency, adaptability, and user-friendliness of the XML-based compiler tools with the help of these integrations. And the target will be the elimination of left-recursive grammars and the development of a global schema for LL(1) grammars, the latter taking advantage of the XML technology, to support the LL(1) grammars construction. The findings in this research not only underscore the signification of these innovations in the field of compilation construction but also indicate a paradigm move towards the use of AI technologies and XML in the context of the resolution of programming traditional issues. The outlined methodology serves as a roadmap for future research and development in compiler technology, which paves the way for open-source software to sweep across all fields. Gradually ushering in a new era of compiler technology featuring better efficiency, adaptability, and all CFGs processed through existing XML utilities on a global basis.

Full textAbstract:
The construction industry’s increasing environmental impact has led to the widespread adoption of sustainability claims, yet the prevalence of greenwashing—where organizations make misleading environmental claims—threatens genuine sustainable development efforts. Environmental Product Declarations (EPDs) have emerged as a potential solution, particularly in the New Zealand and Australia construction sectors, where recent government climate regulations have accelerated their adoption. However, the effectiveness of EPDs in combating greenwashing and their practical implementation remain understudied. This research addresses this gap through a comprehensive analysis of EPDs in construction, employing a systematic literature review of 82 articles from 2010 to 2024 across major databases. Using ATLAS.ti 9 software, this study makes three key contributions: (1) develops a novel framework for evaluating EPD programs and their effectiveness in preventing greenwashing, (2) establishes a standardized methodology for assessing the completeness and accuracy of life cycle assessment information in EPDs, and (3) provides evidence-based recommendations for improving EPD implementation in the construction industry. The findings reveal critical shortcomings in current EPD practices, including inconsistent assessment methodologies and incomplete life cycle data. This study proposes specific reforms to enhance EPD reliability and transparency, offering practical guidelines for industry stakeholders to verify environmental claims. These contributions advance both the theoretical understanding of environmental certification systems and practical implementation of sustainable construction practices by developing regulatory frameworks.

Solar activities are the major sources of space weather that affects human lives. Some of the serious space weather consequences, for instance, include interruption of space communication and navigation, compromising the safety of astronauts and satellites, and damaging power grids. Therefore, the solar activity research has both scientific and social impacts. The major database is built up from digitized and standardized film data obtained by several observatories around the world and covers a timespan more than 100 years. After careful calibration, we will develop feature extraction and data mining tools and provide them together with the comprehensive database for the astronomical community. Our final goal is to address several physical issues: filament behavior in solar cycles, abnormal behavior of solar cycle 24, large-scale solar eruptions, and sympathetic remote brightenings. Significant progresses are expected in data mining algorithms and software development, which will benefit the scientific analysis and eventually advance our understanding of solar cycles.

Construction site monitoring is currently performed through visual inspections and costly selective measurements. Due to the small overhead in construction projects, additional resources are scarce to frequently conduct a metric quality assessment of the constructed objects. However, contradictory, construction projects are characterised by high failure costs which are often caused by erroneously constructed structural objects. With the upcoming use of periodic remote sensing during the different phases of the building process, new possibilities arise to advance from a selective quality analysis to an in-depth assessment of the full construction site. In this work, a novel methodology is presented to rapidly evaluate a large number of built objects on a construction site. Given a point cloud and a set of as-design BIM elements, our method evaluates the deviations between both datasets and computes the positioning errors of each object. Unlike the current state of the art, our method computes the error vectors regardless of drift, noise, clutter and (geo)referencing errors, leading to a better detection rate. The main contributions are the efficient matching of both datasets, the drift invariant metric evaluation and the intuitive visualisation of the results. The proposed analysis facilitates the identification of construction errors early on in the process, hence significantly lowering the failure costs. The application is embedded in native BIM software and visualises the objects by a simple color code, providing an intuitive indicator for the positioning accuracy of the built objects.

4D Building Information Modeling (BIM) is revolutionizing the construction industry by providing an integrated and efficient approach to project management, particularly in large-scale ventures. The primary benefit of 4D BIM lies in its ability to merge the time dimension with the 3D model, enabling detailed simulations of the construction process. These simulations improve visualization, streamline planning, and help identify potential issues early in the process. This proactive approach allows for better resource allocation, optimization, and cost reduction, all of which contribute to faster and more economical project execution. However, while 4D BIM offers significant advantages, its adoption also comes with challenges. The initial investment in technology and software can be high, requiring specialized training for professionals to manage the system effectively. Furthermore, integrating data from different sources and overcoming organizational resistance can hinder its widespread implementation. The complexity of 4D BIM also necessitates a robust change management strategy to ensure smooth adoption and seamless integration into existing workflows. Despite these challenges, 4D BIM’s potential for enhancing the efficiency and sustainability of construction projects is undeniable. As technology continues to advance, and more case studies demonstrate its success, 4D BIM is becoming an essential tool for large construction projects. Additionally, its integration with innovative practices such as Virtual Design and Construction (VDC) and Integrated Project Delivery (IPD) further strengthens its value, positioning it as a critical element in the future of the construction industry.

Full textAbstract:
A high-performance technology for constructing cased wells is proposed. Essence of the technology is the advance insertion of the casing pipe into the sedimentary rock mass and the cyclical-flow transportation of the soil rock portions using the compressed air pressure supplied to the open bottomhole end of the pipe through a separate line. Results of mathematical modeling for the process of impact insertion of a hollow pipe into a soil mass in horizontal and vertical settings are considered. Modeling of the technology is implemented by the finite element method in the ANSYS Mechanical software. Parameters of the pipe insertion in the sedimentary rock mass are determined - value of the cleaning step and the impact energy required to insert the pipe at a given depth. Calculations were performed for pipes with a diameter from 325 to 730 mm. Insertion coefficient is introduced, which characterizes the resistance of rocks to destruction during the dynamic penetration of the casing pipe in one impact blow of the pneumatic hammer. An overview of the prospects for the application of the proposed technology in geological exploration, when conducting horizontal wells of a small cross-section using a trenchless method of construction and borehole methods of mining, is presented. A variant of using the technology for determining the strength properties of rocks is proposed. Some features of the technology application at industrial facilities of the construction and mining industry are considered: for trenchless laying of underground utilities and for installing starting conductors when constructing degassing wells from the surface in coal deposits. Results of a technical and economic assessment of the proposed technology efficiency when installing starting conductors in sedimentary rocks at mining allotments of coal mines are presented.

AbstractIn this study, finite element software was utilized to delve into the intricate tensile mechanism of ultra‐high performance concrete (UHPC)‐steel bridge panels subjected to loading in a large‐span arch bridge. Specifically, the analysis pinpointed the most unfavorable location to be the critical juncture where the transverse girder intersects with the small longitudinal girder, precisely at the midpoint of the span. Consequently, a novel crack control strategy tailored for the UHPC layer of center‐bearing large‐span arch bridges was formulated, which involves the strategic “releasing of horizontal ropes in advance, followed by replenishing tension at a later stage.” Furthermore, the pivotal technology pertaining to the construction of the UHPC‐steel deck pavement layer was established through rigorous on‐site experimentation and implementation.

<abstract> <p>As speech recognition technology continues to advance in sophistication and computer processing power, more and more recognition technologies are being integrated into a variety of software platforms, enabling intelligent speech processing. We create a comprehensive processing platform for multilingual resources used in business and security fields based on speech recognition and distributed processing technology. Based on the federated learning model, this study develops speech recognition and its mathematical model for languages in South China. It also creates a speech dataset for dialects in South China, which at present includes three dialects of Mandarin and Cantonese, Chaoshan and Hakka that are widely spoken in the Guangdong region. Additionally, it uses two data enhancement techniques—audio enhancement and spectrogram enhancement—for speech signal characteristics in order to address the issue of unequal label distribution in the dataset. With a macro-average F-value of 91.54% and when compared to earlier work in the field, experimental results show that this structure is combined with hyperbolic tangent activation function and spatial domain attention to propose a dialect classification model based on hybrid domain attention.</p> </abstract>

With the innovative advance in science and technology, manufacturing production methods have made considerable progress. However, before the production process is actually implemented, it is important to examine whether the design can meet the actual need. By applying cyber-physical system technology to test the production process, the development problems of the actual construction can be avoided. Based on the existing components, this study incorporated the cyber-physical system via innovative integration. In addition to the human–machine interface, this was employed as the operating spindle to integrate the material color identification system of the physical organization. This study also adopted the automated virtual factory constructed by the simulation software of Factory IO with an aim to achieve the technical application.

The results of many years of research on the prevention of complications in the construction of oil and gas wells using machine learning methods are presented in the article. The issues of creating prototypes of intelligent systems to prevent complications when drilling wells on land and offshore are considered. The purpose of the intelligent systems to prevent complications during well drilling is to warn the driller in advance about the possibility of a violation of the regular drilling regime. Intelligent systems for preventing complications during well construction help to increase the economic efficiency of drilling oil and gas wells. Large volumes of geodata from the stations of geological and technological measurements during drilling vary from units to hundreds of terabytes. Creation of the neural network modeling software components is aimed at revealing hidden and non-obvious patterns in the datasets, i.e. in the processed, labeled and structured information from the stations of geological and technological measurements in the tabular form. Hierarchical distributed data warehouse was formed containing real-time drilling data in WITSML format using a SQL server (Microsoft). The geodata preprocessing and loading module for the WITSML repository uses the Energistics Standards DevKit API and Energistic data objects to work with the geodata in the WITSML format. The accuracy of predicting drilling problems achieved with the help of the developed intelligent systems can significantly reduce unproductive time spent on eliminating stuck pipes, mud losses and gas, oil and water shows. Large-scale implementation of the intelligent systems to prevent complications in well drilling will ensure the achievement of a zero-carbon footprint in the environmentally friendly drilling of wells on the land and offshore.
