DIGITISATION OF RETREATING INDUSTRIAL HERITAGE; MODELLING THE DECOMMISSIONING OF THE COAL WASHERIES OF ONLLWYN

Abstract. Digitisation for the purposes of recording cultural heritage and its condition is conventionally associated with the task of documentation for conservation. Occasionally emergency recording will anticipate the potential imminent destruction of heritage at risk. By contrast here, although the heritage status of the site whilst proposed in the 1990s, it was never secured yet the closure and eventual dismemberment of the buildings is a plan that is already underway. The coal washeries of Onllwyn sit within a vast landscape that is now most widely recognised as a National Park. During the last century, however, it was a thriving industrial site. The assembly of buildings used to wash and sort coal prior to distribution were recorded using a terrestrial laser scanner and an aerial drone in August 2022 shortly prior to the closure of a site that had been part of a changing industrial landscape since the mid-nineteenth century. As part of a wide agreement to build a historic narrative for a once large industrial site with a planned closure a comprehensive historical review has been built. This included the acquisition of historic maps but also of numerous historical aerial and terrestrial photographs as well as the collation of films and oral histories. Here pointclouds generated from terrestrial laser scans, photogrammetry from drone imagery and photogrammetry from historical aerial images have been combined in an attempt to create a navigable digital backdrop to the decommissioning of a vast industrial landscape as it anticipates a new future. The aim of the models created is to provide a virtual spatial platform to co-locate memories of a community life that is left centred around a lost place of work.

경주지역 신라사찰 출토 매납토기의 용도와 특징

This study investigated the usages, characteristics, and chronological records by categorizing the earthenware buried in fixed or inverse positions as a unit-structured relic in the major temples of the Silla era, which are located in the capital area of Silla within Gyeongju, such as Hwangnyongsa Temple Site, Bunhwangsa Temple, Jeoninyongsa Temple Site, Cheongwansa Temple Site, and Changnimsa Temple Site. It was confirmed that most temples of the Silla era included a large gourd-shaped building assembly site (大壺群集建物址). The large gourd-shaped building assembly sites were typically located in the surroundings of the northeast areas, especially the northern part of the central temple site. This locational pattern also appeared at the temples in the Baekje area and the royal capital area of Japan during the same period, and certain norms must have been applied to the space layout of the building during the construction of temples. This study, in particular, identified that the usage of large kettle-shaped building assembly sites was a conventional warehouse or a storage facility, but it also raised a possibility of a brewing facility. The items suppressing the bad energies of the ground buried in the temples of the Silla era were typically connected to the stylobates or cornerstones of a specific building and were often positioned around a pagoda or special building sites, exhibiting in a certain direction. Such a burial activity was perceived as an intentional and ceremonial event, and was understood to be stemmed from traditional religious rituals or religious aspirations toward specific objects. There are some potteries that exhibit the characteristics of an item containing human bones among the buried potteries classified into the conventional items suppressing the bad energies of the ground in the surrounding temple sites away from the Buddist service area which is the center of a temple. In the future, the analysis on the natural scientific contents of the buried earthenware is further required in surveys of temples and real-life historical remains.

Efficient homology-based annotation of transposable elements using minimizers.

Transposable elements (TEs) make up more than half of the genomes of complex plant species and can modulate the expression of neighboring genes, producing significant variability of agronomically relevant traits. The availability of long-read sequencing technologies allows the building of genome assemblies for plant species with large and complex genomes. Unfortunately, TE annotation currently represents a bottleneck in the annotation of genome assemblies. We present a new functionality of the Next-Generation Sequencing Experience Platform (NGSEP) to perform efficient homology-based TE annotation. Sequences in a reference library are treated as long reads and mapped to an input genome assembly. A hierarchical annotation is then assigned by homology using the annotation of the reference library. We tested the performance of our algorithm on genome assemblies of different plant species, including Arabidopsis thaliana, Oryza sativa, Coffea humblotiana, and Triticum aestivum (bread wheat). Our algorithm outperforms traditional homology-based annotation tools in speed by a factor of three to >20, reducing the annotation time of the T. aestivum genome from months to hours, and recovering up to 80% of TEs annotated with RepeatMasker with a precision of up to 0.95. NGSEP allows rapid analysis of TEs, especially in very large and TE-rich plant genomes.

Simulation modeling of the lifting and assembly module of the supports of the structural coating

The materials of the article are devoted to the issue of simulation modeling of construction mechanized technological equipment, in particular, modeling of the lifting and assembly module for the installation of a structural coating. Today, an urgent task in the construction market is the construction of large-scale structures, the life cycle of which is shortened, but the construction terms are reduced. Such a need exists in the construction of shelter hangars, field hospitals, warehouses, etc. As a rule, for urgent needs, buildings with light construction structures are erected, the covering of which is formed by structural blocks. A feature of such structures is multi-element support elements. A lifting assembly module is proposed for the installation of such structures.
 It is essential that the mounted structural coating is assembled on the heads of the lifting and collecting modules in blocks, and the lifting of the structural block to the design mark occurs thanks to the module while simultaneously raising/assembling the supporting elements of the coating. Simulation computer modeling tools were used to study the possibility of implementing the assembly process using the lifting assembly module. It is proposed to use the parametric formation of sketches and 3D models when forming the design features of the module. The dissection of the elements of the new assembly module, support elements and structural coating to the level of simple parts made it possible to determine their mass characteristics with sufficient accuracy. The basic technical indicators of the assembly module and building structures, which can be used in the development of the assembly technology, were obtained.
 Approaches to the use of cloud databases when using unified elements during design are defined.The use of simulated geometric modeling data allows to analyze the strength properties of the components of the technical system and, together with the visual observation data, to create a common information model of the building object with the possibility of qualitative analysis of the indicators of the specified elements of building structures.

How Much Agency Does Architecture Have?

Abstract Dhaka's National Assembly building, designed by Louis Kahn, was built over several turbulent decades as East Pakistan fought for autonomy and became the new country of Bangladesh. Conventional critical narratives situate the National Assembly within Kahn's biography, treating Bangladesh as an empty canvas on which Kahn could enact design philosophies developed over his career. I contend that architects and critics are not the only arbiters of a building's meaning, and that local and political context should not be ignored in a building's historical narrative. There is ample recent scholarship decentering the Western canon, to which the National Assembly belongs, in architecture history, theory, and criticism. This article calls for decentering the architect as well, and acknowledging that the client's agenda, historical context, local interventions, popular perception, and the ongoing use of a building all influence the many layers of meaning architecture acquires over time. Continuing to perpetuate the myth of the lone artistic genius doggedly pursuing his creative vision gives unfounded agency to the individual architect alone. Design has agency and buildings shape worlds, but buildings themselves are shaped by complex collective actions, not singular visions. As a Western architect called to build on a grand scale in Asia, Kahn is an early example of a now prevalent trope. This research establishes a template for understanding this kind of work in context, and acknowledging the crucial role played by local actors in shaping each project and determining the project's cultural significance over time.

WAYS OF TRANSMISSION OF ETHNOCULTURAL UNITS IN THE CORPUS

The paper substantiates the need to include in the national corpus of the Kazakh language the names of material culture in the system of ethnocultural units of the Kazakh language through their description, as well as the need for their marking in the corpus.Ethnocultural units are linguistic symbols with a large cumulative function, reflecting the national identity of the Kazakh language, preserving the language, traditions, worldview, and spiritual world of the nation. Therefore, the language is supported by national culture.Currently, intensive language study is being conducted in an anthropocentric direction. In this regard, the deepening and expansion of the process in this direction are determined by the relevance of the assembly of national buildings. The national corpus of the Kazakh language is a modern innovative and informational tool that serves as a guardian of such national cultural units in a broad way, a carrier of them for generations.The research paper describes the ways of introducing ethnocultural units into the National Corpus of the Kazakh language: coding, modeling, and using algorithmic and programmatic approaches when introducing ethnocultural units into the National Corpus. First of all, collecting ethnocultural units that are the basis for creating the corpus base, determining their cultural and semantic groups and compiling a list of words related to this the group. Transfer each of them to professional programmers only after applying the markup code. Programmers must work on a certain algorithm and carry out further processing. Works to be done in the future are considered as well.The research work is dedicated to the consideration of the issues of inclusion in the corpus of the Kazakh language of markings defined based on the National corpus of the Kazakh language (morphological, word-formation, semantic, lexical, phonetic, and phonological markings) as cultural and semantic markings.

Constructing geographical and architectural imaginations: The China-aided assembly buildings in Africa, 1960s – 1970s

China’s exports of architectural designs to numerous countries in Asia and Africa during the Mao era generated significant tensions regarding the necessary geographical knowledge. As many of these countries are situated in tropical regions, understanding and responding to the unique hot, humid or dry climate conditions was crucial for successful transnational architectural production. This article situates the practical knowledge generation process within a complex process of political, institutional, individual, and intellectual interactions, examining the role of Chinese architects and technocrats in constructing geographical and architectural imaginations for China-aided projects built in Africa. Specifically, in this article, two case studies of assembly buildings erected in Guinea (1967) and Sudan (1976) are presented to demonstrate Chinese efforts to address the climatic, cultural, and practical requirements of architectural aid. Through political negotiation, personal observation, onsite visits, media publication, and scholarly exchange, Chinese professionals constructed geographical and architectural imaginations in Africa, creating modernist architecture that retained a particular sense of place and time, thereby reflecting continuity and transformation of their domestic work. These subjective imaginations were shaped by the combination of economic rationality and technical expertise, manifested in the selection of appropriate site, climate responsive designs, materials, technologies, cultural articulations, and economic considerations. The aided buildings, as embodiment of the Chinese professionals’ geographical and architectural imaginations not only displayed a critical process of knowledge production situated within the physical, material world in the tropics, but also served as China’s political engagement with Guinea and Sudan that aimed to interrogate existing structure of international order.

The main installation operations are analyzed with an indication of the time spent on each floor and the roof arrangement.
 
 Results. based on the final results of the timekeeping materials generalization, three estimates of the duration of a building construction of large-sized blocks are proposed — pessimistic, satisfactory, optimistic. The found dependences “duration of building construction — the number of large–sized blocks installed taking into account the roof arrangement” are revealed with the corresponding calculation formulas. The formula for calculating the labor intensity of installers work and crane maintenance workers is also given.
 
 Conclusions. the prospects for the innovative technology development for the construction of residential buildings of large-sized blocks are substantiated, provided that capital investments are allocated and the efforts of research and design organizations are combined to comprehensively solve the problems that have arisen. To solve the problematic tasks of determining the indicators of organizational and technological parameters of buildings construction of large-sized blocks, an approach and methods for assessing the duration of construction and the complexity of installation work on the assembly of buildings are proposed.

Lessons in large-sample laboratory sound transmission loss testing

Thousands of laboratory sound transmission loss tests, in accordance with the ASTM International Test Method E90, reveal some trends that challenge multiple aspects of building sound isolation. Some notions about sound transmission through building assemblies are accepted industry-wide that these current studies bring into question. The applicability of the Sound Transmission Class (STC) rating system also becomes challenging when observing trends in large and varied data samples. From preliminary small-sample studies to measure uncertainty across laboratories to large-sample observations of assembly test data, this presentation offers guidance for both the development of standards in the building sound isolation industry and for education in the building design process.

Structural analysis of the ex-port plug collective thomson scattering transmission lines for ITER

The main function of the Collective Thomson Scattering (CTS) diagnostic system for ITER is to diagnose the alpha particles resulting from Deuterium-Tritium fusion reactions. It consists of a microwave scattering diagnostic with a probing frequency of 60 GHz and emitted power of 1.2 MW from the gyrotron, with one launcher and nine receiver transmission lines.The CTS will be installed in the equatorial port EP#12, which is one of the ports that have to be operational for the ITER First Plasma. The transmission lines outside the Port Plug (Ex-PP) are routed through the Interspace, Port Cell, Gallery, Assembly Building and Diagnostic Building, reaching more than 100 m in length. The preliminary design of the ex-PP components is currently being undertaken in the framework of an Implementing Agreement between ITER Organization, the Instituto Superior Técnico (IST) and CIEMAT. Within this collaboration, CIEMAT is responsible for the structural analyses and calculations required to ensure the structural integrity and performance of the preliminary design of the Ex-PP transmission line components, which will be summarized in this paper.In this work, the required analysis and calculations will be presented together with the redesign performed for the transmission lines in order to guarantee that their components will withstand the loads defined in the Ex-PP CTS Load Specifications. The evaluation of the structural integrity of the CTS Ex-PP components will be carried out in accordance with the 2007 RCC-MR Code for mechanical components in nuclear installations.

Study on temperature-humidity controlling performance of zeolite-based composite and its application for light quality energy-conserving building envelope

A composite thermo-hygroscopic material with loose surface, neat and single pore size distribution for lightweight envelope structure was hereby prepared in this paper by compounding inorganic minerals with polymer materials using the sol–gel method. The moisture storage capacity, isothermal humidity control characteristics of this material were studied through static isothermal humidity controlling performance experiments. Besides, its performance in terms of the air temperature, relative humidity, moisture content in the light-weight assembly building (movable panel house), laying thickness, and laying area on the indoor air parameters were studied under the action of outdoor climate conditions and indoor periodic humidity load using the effective humidity penetration thickness model. It was found that under winter conditions, the laying of CHPCMs can moderate the effects of outdoor temperature and humidity load changes on indoor temperature, relative humidity and moisture content, and effectively delay the fluctuation of indoor air parameters. CHPCM exhibits an optimal laying thickness value, and the deviation from the optimal thickness value can weaken its ability to regulate indoor environmental parameters. The average air relative humidity of the naturally ventilated room with a laying area of 24 m2 is about 4.6 % lower than the average air relative humidity with a laying area of 12 m2.

Dose-response simple isopleth for mold (DR SIM): A dynamic mold growth model for moisture risk assessment

A new mold growth model was developed to aid in moisture risk assessment of wood-based building assemblies. This proposed simple model relies on several features common to existing mold growth models but combines them in a new way with improved predictive power. Structurally the model is based on a dose-response relationship. Hygrothermal conditions conducive to mold growth are represented using a mold germination isopleth, i.e., a critical relative humidity curve as a function of temperature. The dose at a given time step depends on the difference between surface relative humidity and the critical relative humidity. Doses are accumulated over time and a sigmoidal function relates cumulative dose to predicted mold rating. During unfavorable conditions, the predicted mold rating does not decline; rather, it remains constant and again increases once favorable conditions resume, subject to a recovery period. The model parameters were optimized using a large database of laboratory growth results obtained from the literature. The model was shown to have improved predictive power compared to an earlier model, and to be consistent with available field data. A key model feature is the ability to capture numerically the stochastic nature of mold growth using a deterministic mathematical form. The Dose-Response Simple Isopleth for Mold (DR SIM) model thus provides a useful tool for detailed moisture risk assessment using hygrothermal simulation or field data inputs of temperature and relative humidity.

Analysis on construction practice of intelligent prefabricated building based on BIM technology

In the rapid development of Chinese construction industry, intelligent assembly building construction based on low cost, high efficiency and other advantages, in the practice of inquiry has been widely paid attention to. Although scholars around the world have strengthened the research on the theory of intelligent prefabricated building construction technology, with the vigorous development of the construction industry, a large number of safety problems have emerged in existing construction projects. Therefore, some scholars have proposed to scientifically solve the problems faced by intelligent prefabricated building construction management with the help of information integrated BIM technology, so as to build a highly efficient and normative safety management system. On the basis of understanding the construction management of intelligent prefabricated building and the research status of BIM technology, this paper deeply discusses how to apply BIM technology in intelligent prefabricated building construction and give full play to the unique advantages of BIM technology according to the main characteristics and construction requirements of intelligent prefabricated building construction in the new era.

Analysis of Design Method and Mechanical Properties of Plug-In Composite Shear Wall

Assembly buildings are an important direction for the future development of the construction field. They can be prefabricated in the factories and then assembled on-site, which significantly improves construction efficiency. The shear walls are the most important lateral force-resisting elements in building structures, and at this stage, there are more and more studies on the prefabricated shear wall. In this paper, a new composite shear wall structure is proposed. The composite shear wall is a part of a prefabricated building, which is prefabricated into a single shear wall unit in the factory. During the construction, the upper and lower prefabricated shear wall units are connected by the plug-in. The design methods of splicing connection are given for the design of this composite shear wall structure. Eleven composite wall models under different parameters are established by using the finite element method, especially the fine modeling of the upper and lower connection parts. Compared with the conventional composite shear wall model of the same dimensions, the mechanical behaviors of the two models are similar. In the simulation of cyclic loading, the new composite shear wall shows good ductility and energy dissipation capacity, and also meets the established requirements of building seismic performance. Therefore, it can be concluded that the new prefabricated composite shear walls have good development prospects and application values.

A facile green and cost-effective manufacturing process from coal gangue-reinforced composites

Utilization of high-filler coal gangue (CG) to produce cost-effective composites is a promising strategy. To clarify the impact of high-filled CG on composite preparation and performance, in this research, the composite was prepared from CG and polyethylene (PE) through physical mixing and then hot-pressing. The role of CG in the properties of the composites and the influence of the interface formation mechanism are obtained by establishing the relationship between CG content and the composites' feature. The results show that: high-filler CG is helpful to the increment of the composite's mechanical and thermostable properties. When the CG addition is up to 80%, the density and hardness from 0.93 g/cm3 and 50.5 HD increased to 1.60 g/cm3 and 66.5HD, which was increased by 72.0% and 31.6%, respectively. Meanwhile, the bending strength and modulus reach 17.5 MPa and 3400.6 MPa, which is respectively exceeded by 56.3% and 628.6% than composite from pure PE (11.2 MP and 466.7 MPa). In addition, high-filler CG is beneficial for the enhancement of entanglement between CG and PE during the composite preparation, and has the effect of heterogeneous nucleation, which facilitated the crystallization and thermal stability of the composite. The properties of the composites prepared by this simple technique meet national standards and are more economical and environmentally sustainable than composites prepared with other fillers. This new material holds great promise for the development and realisation of carbon-neutral decorative materials such as assembly buildings, vehicles and coloured panels.

A Research into Chiral Thiosemicarbazide Compound: XRD Analysis, Hirshfeld Surface Analysis, and Energy Framework

The present work combined single-crystal XRD analysis, Hirsfeld Analysis, and energy framework analysis to interpret and comprehend the overall building of supramolecular assemblies by predicting the hydrogen bond interactions present in the (+)-(R)-1-[2-(benzenesulfonamido)-3-phenylpropanoyl]-4-(phenethyl)thiosemicarbazide[RBPPT] compound. According to XRD analysis results, the compound had one independent molecule in the unit cell (V = 252.1(2) Å3, Z=2), and a crystalized monoclinic crystal system (β=104.401 (3)˚) with P21 space group. Also, intermolecular hydrogen bonds formed supramolecular assemblies in the compound and non-traditional hydrogen bond interactions (π-ring) were investigated by Hirshfeld surface and 2D fingerprint analysis. Energy framework analysis was computed and investigated by the energy density wave function of B3LYP/6-31G(d, p), which elicits the supremacy of dispersion energies via standard electrostatic energy frameworks.

Application of BIM Technology in New Assembly Type Green Building

With the acceleration of urbanization in China, ecological construction has become an increasing concern. In order to achieve sustainable development, we must establish green buildings, which requires green buildings to continuously innovate and optimize technologies and techniques, and consciously adopt new technologies and means, so that they can better adapt to the development of today's society. In addition, BIM technology is an emerging technology that has been widely used in various fields such as engineering project design, construction progress, construction building and operation management. Therefore, the application of BIM technology in the new green assembly building is discussed, which is an important reference value for the construction and building of modern building projects.

Research on safety evaluation of assembly building construction by integrating entropy power method and network analysis model

Unlike the traditional construction mode of rough operation, assembly building construction implements the concept of green development in terms of energy consumption and environmental adaptability. Although assembly construction can effectively reduce construction energy consumption and improve the environmental resilience of building construction work, there is an urgent need for an effective safety assessment model for construction development due to the imperfect operation system and harsh construction environment in the construction industry. Therefore, the study analyzes the relationship of construction safety factors by using Analytic Network Process (ANP) to filter safety evaluation indexes according to the importance ranking. At the same time, the objective weights of safety indicators were determined by the entropy weight method, and the subjective weights determined by the ANP method were combined to construct the safety evaluation model for the construction of assembled buildings. The experiment shows that the maximum similarity between the comprehensive evaluation results of the model in the simulation of safety evaluation of high-rise residential construction and the actual evaluation criteria is 0.772. The experiment proves the reliability of the evaluation of the model, which reduces the safety loopholes and operation hazards for the construction of assembled buildings.
