Abstract
In order to obtain the material model parameters for numerical simulation of the ballistic performance of high nitrogen austenitic stainless steel (HNASS) perforated armour, the static and dynamic mechanical properties and material fracture experiments of HNASS have been carried out. Parameters for the Johnson-Cook constitutive and failure model were then adjusted based on the experimental findings. The penetration process of perforated armour against 12.7 mm armour-piercing incendiary shells (API) was simulated by AUTODYN software and the simulation results were compared with the ballistic test results. The findings indicate that using model parameters acquired from mechanical experiments for penetration simulation results in matching failure modes of the perforated armor and penetration depths of body armor with test outcomes, confirming the reliability of the model parameters.

Authors: Li Dongqin , Lu Lingfeng 
Published: August 2024

Abstract
To solve the problem of complex and time-consuming simulation calculations in ship type optimization, the application of approximate model technology based on spatial segmentation sequence sampling is becoming increasingly widespread. Based on the Kriging approximation model and the cross-leaving one error method, a new sampling strategy is proposed during the iterative sampling process. The importance of adding sample subspaces and surrounding subspaces is considered in the design space, and parallel thinking is added to develop an efficient parallel sequence sampling method to improve sample aggregation. The proposed method was applied to optimize ship types, and its effectiveness was verified.

Authors: Gao Yuan , Niu Haoying , Zhang Bingbing 
Published: August 2024

Abstract
In order to study the mechanical properties of slag micropowder cured red layer filler and its microscopic action mechanism, the mechanical properties of red layer filler with different dosages of slag micropowder were investigated by using test methods such as no lateral limit and straight shear, and the microscopic properties and improvement mechanism of slag micropowder cured red layer filler were analysed by using test methods such as X-ray diffraction, infrared spectroscopy, laser particle size, nuclear magnetic resonance, thermogravimetric analysis, and scanning electron microscopy. The experimental results show that the addition of slag powder can significantly improve the mechanical strength and water stability of the red-layer filler. The microscopic experiments such as X-ray diffraction and infrared spectroscopy proved that the action mechanism of slag micropowder-modified red layer filler is ion exchange and hydration. More importantly, using scanning electron microscopy (SEM), it can be visually observed that the improved red layer filler causes the soil particles to flocculate into sheets or clumps with the increase of hydration gel materials, forming lamellar accumulation or flocculation structures, and the structural integrity is significantly improved.

Published: August 2024

Abstract
Seagrass meadows store significant amounts of carbonate (CaCO3) in sediment, contributing to coastal protection but potentially offsetting their effectiveness as carbon sinks. Understanding the accumulation of CaCO3 and its balance with organic carbon (Corg) in seagrass ecosystems is crucial for developing seagrass-based blue carbon strategies for climate change mitigation. However, CaCO3 accumulation in seagrass meadows varies significantly across geographic regions, with notable data gaps in the Caribbean and Central America. Here, we sampled 10 seagrass meadows across an extensive island chain in The Bahamas, part of the largest seagrass ecosystem and one of the largest CaCO3 banks globally, to evaluate CaCO3 stock, accumulation rate, and its balance with Corg sequestration. Seagrass meadows in The Bahamas store 6405–8847 Tg of inorganic carbon (Cinorg) in the upper meter sediment, with an annual accumulation rate of 38.3–52.9 Tg of Cinorg, highlighting these meadows as hotspots for CaCO3 burial. CaCO3 contributes 67 ± 8% (mean ± standard error) of the sediment accumulation, indicating its important role in seabed elevation. Sediment Cinorg showed no significant relationship with Corg, with an average Corg : Cinorg ratio of 0.069 ± 0.002, ∼ 10 times lower than the threshold (Corg : Cinorg ratio of about 0.63) at which seagrass ecosystem transition from CO2 sources to sinks. However, the available air–sea gas flux measurement was only 1/5 of the calculated CO2 emission expected from calcification, suggesting that part of the accumulated CaCO3 is supported by allochthonous inputs. Furthermore, no perceivable relationship between seagrass density and either CaCO3 stock or accumulation rate was observed, indicating that seagrass may play a limited role in supporting CaCO3 production. Further studies on water chemistry, calcification rate, air–sea CO2 flux, and comparison between seagrass and unvegetated habitats are required to elucidate the carbon budget of this globally significant ecosystem.

Published: August 2024

Abstract
The Malaysian Garden concept (MGC) is guided by principles and criteria reflecting traditional Malay design elements and contemporary approaches. Previously, the criteria of the guidelines provided by the National Landscape Department (NLD) for Malaysian Garden design can be used as a reference to evaluate the implementation and design enforcement of public parks in Malaysia. However, the effectiveness of these guidelines in achieving the desired aesthetic and functional goals of Malaysian Gardens needs to be clarified. As Malaysia undergoes rapid social, cultural, and environmental changes, the existing guidelines must be more relevant and applicable. Thus, there is a need to critically examine and compare traditional and contemporary approaches to Malaysian Garden design and evaluate the effectiveness of current guideline criteria in achieving desired outcomes. The study’s objective is to determine how effective these criteria are in achieving the desired aesthetic and functional goals of Malaysian Gardens and the limitations of these criteria. The study adopted a comparative analysis approach to analyze traditional and contemporary Malaysian Garden designs and evaluate their adherence to current guidelines. The comparative analysis between traditional and contemporary approaches is interesting and valuable. It allows the researchers to evaluate the effectiveness of existing criteria considering current needs and evolving cultural contexts. The study also involves interviewing Malaysian Garden experts and other relevant stakeholders to gain insights into their perspectives on current guideline criteria and potential modifications to reflect current needs better. This study can catalyze development guidelines or recommendations for implementing Malaysian Garden design principles in public parks. Analysis of existing public parks in Malaysia to assess the extent to which they adhere to Malaysian Garden design guidelines and identify areas for improvement. The study’s findings will contribute to developing more effective guideline criteria for Malaysian Garden design that reflect the country’s cultural heritage and current needs.

Ngarsopuro and Gatot Subroto corridor is one of the main corridors in downtown Surakarta due to its strategic location in CBD (Central Business District) area and the two sultanate areas of Surakarta (Mangkunegaran and Kasunanan). The site’s function influences pedestrian activity in this corridor as a cultural arts tourism center. Pedestrian comfort is a priority in the arrangement of an urban area. Pedestrian comfort is one aspect of the concept of walkability. This study aims to identify the quality and pedestrian facilities in tourist areas using the concept of walkability. The method used in this research is a descriptive qualitative method through field observation to observe and identify the condition of pedestrian facilities in the Ngarsopuro and Gatot Subroto corridors. The discussion compared the corridor’s existing situation with the walkability principle. The results showed that the quality of pedestrian paths on the Ngarsopuro and Gatot Subroto corridors needs to be improved. Some of the problems found are the lack of greenery, the lack of facilities for disabled people, and the condition of the facilities that are not maintained. This issue affects the comfort of pedestrians, who are actors in the concept of walkability. The study’s results are expected to be an evaluation and input in improving the quality of pedestrian ways in tourist areas.

Authors: Darmayanti Tessa Eka 
Published: August 2024

Abstract
Globalization unconsciously affects changes in needs and behavior in a place and changes in one’s mindset about places and conditions. Challenges arise from this circumstance, particularly in terms of preservation. In this case, rebuilding space is an action by policyholders that is seen as a form of preservation and sustainability of a place. The Great Mosque of Banten is the focus of the discussion because it provides an overview of the relationship between rebuilding the place and the preservation that prevails in it. This study aims to provide an understanding of which components influence the embodiment of new places as a result of rebuilding. Additionally, this is expected to provide a new angle on seeing, experiencing, and interpreting a place. This qualitative research begins with surveys, interviews, and observations. So that there is optimization in the discussion, it uses literature studies and is supported by a third space concept approach, especially perceived space. Through this research, it was found that a rebuilding place occurs simultaneously with various changes in terms of tangible and intangible so that a place is not just a container, space, or place for activities, but also a place that has value. Rebuilding the place, also shows that the beauty of the place is not only a matter for the eyes but the senses.
Analysis of Local Resources for the Formation of Modern Public Commercial Centers on the Material of Kharkiv
Authors: Borysenko A S 
Published: August 2024

Abstract
An exploratory three-level analysis was conducted to identify local resources for the design of modern shopping centers integrated into the urban structure of Kharkiv. It included a historical analysis of its commercial spaces, a typological analysis of modern shopping centers, as well as an online survey of residents regarding their use of commercial spaces. The typological composition of shopping centers in Kharkiv indicates predominance of introverted spatial organization, with absence of thematic shopping centers focused on aesthetic qualities of their environment. Resources provided by the peculiarities of regional situation can contribute to creation of such solutions. Among them are architectural images that accompanied the development of commercial buildings in the city, complex three-dimensional solutions of their prominent examples, as well as the use of temporary functions integrated into a flexible structure. The interest of respondents of an online survey in open, green, but at the same time protected spaces indicates mixed spaces of variable use as an unused resource in the conditions of Kharkiv. The available set of local resources highlights the potential for creating a sustainable shopping center of thematic type with characteristic regional features. Further research for its implementation may be carried out situationally, on specific location-related data.

Authors: Izbash Yu , Babayev V 
Published: August 2024

Abstract
In recent decades, the Architecture, Engineering, and Construction (AEC) industry has witnessed profound shifts driven by digital technologies. Central to this transformation is Building Information Modelling (BIM), which has offered a holistic approach to design, analysis, and documentation, yielding benefits in visualization, collaboration, simulation, and life-cycle management. However, the industry’s intricate regulatory landscape, primarily rooted in traditional text-heavy building codes, has lagged in digital adaptability. This paper explores the imperative to transition building codes and regulations into machine-friendly formats, capitalizing on structured databases, semantic annotations, and (Application Programming Interface) API-driven access. Such a transformation facilitates streamlined (Artificial Intelligence) AI-based compliance checks and augments the capabilities of BIM systems. Furthermore, the research delves into the convergence of BIM with other burgeoning technologies. Extended Reality (XR) promise enriched visualization and on-site integration. AI introduces automated analytics, optimization, and predictive facilities management. The integration of Internet of Things (IoT) proposes a real-time feedback loop into BIM, evolving towards dynamic Digital Twins. The discussion also touches upon the potential of XR technology use for enhanced workforce performance and quality control on the site. In conclusion, the AEC industry stands on the edge of a digital evolution, demanding integrated approaches to fully harness the potential of these technologies, ensuring not only efficient construction practices but also enhancing building safety and sustainability.

Published: August 2024

Abstract
The formulations were developed for road over-stabilized cationic bitumen emulsions on hydrochloric acid and cation-active emulsifiers. There were determined the physical-mechanical properties of the bitumen emulsions produced, while special at-tention was paid to the emulsions breaking behavior. There was defined the influ-ence of the emulsifier content and type upon the bitumen emulsions’ physical-mechanical indices, as well as upon the breaking behavior – by four methods: break-ing value, miscibility with open-grade and dense-grade mixes, fines mixing time, mixing stability with cement. The emulsifier content makes the most impressive in-fluence upon such bitumen emulsion property as stability during storage: residue on sieving (sieve No 014). The results obtained for bitumen emulsions breaking behav-ior (by various testing methods) show the substantial correlation, especially if to compare the breaking value and mixing stability with cement. The miscibility with open-grade and dense-grade mixes provides not just for estimation of a visual cover-ing and combining of emulsion with aggregate, while fines mixing time in all the emulsions tested was more than 300 seconds. Therefore it was defined that the most expedient testing methods for breaking behavior (such ones, which allow defining whether an emulsion is either slow-setting or over-stabilized) are as follows: breaking value and mixing stability with cement. With growth of emulsifier content the break-ing value increases, while mixing stability with cement decreases. Besides, upon the replacement of emulsifier, intended for slow-setting emulsions for the other emulsi-fier, recommended for over-stabilized emulsions, the breaking value substantially in-creases, while the mixing stability with cement rapidly decreases.

Abstract
Urbanisation processes contribute to an increase in the level of harmful emissions in cities, which significantly increases the relevance of sustainable inclusive development based on the principles of decarbonisation and the transition to zero-emission cities. The purpose of the study is to summarise the global experience of implementing sustainable urban development programmes and their transition to zero-emission cities and to develop proposals for its implementation in the substantiation of urban development programmes in Ukraine. The study is based on a system of methods that includes conceptual approaches to sustainable inclusive development based on a balanced approach, generalisation of global digital trends in the transition of cities to zero CO2 emissions, practical results of decarbonisation projects and identification of indicators for their achievement. In the context of the formation of “smart” city strategies in Ukraine, the current areas of decarbonisation of urban development, based on the feasibility and limited funding, are optimisation of urban traffic, creation of “green” zones with zero emissions, implementation of a set of measures and introduction of renewable energy, promotion of projects that reduce greenhouse gas emissions in construction, including their reduction at all stages of the life cycle of buildings, as well as the implementation of a “smart” waste management system Based on a synthesis of international experience, the study outlines the basic indicators for achieving decarbonisation goals, which can be used in the future to substantiate sustainable development strategies for Ukrainian cities.

Published: August 2024

Abstract
The aim of this work was to determine the temperature and pressure on the quality of charcoal, obtained in the renewable energy pyrolysis of coniferous residues. Charcoal yield is found to be steadily reduced with increasing pyrolysis temperature. It was found the pyrolysis temperature increasing up to 700 °C, the pressure decreasing up to 0.1 MPa and the yield of charcoal decreasing up to ~34.5%. It is proved that the renewable energy pyrolysis temperature increasing up to 700 °C at a constant pressure level (0.1 MPa), as well as the pressure increasing up to 2 MPa at a constant temperature (550 °C) leads to an increase in FCd and HHV. The generalization of the obtained experimental studies makes it possible to optimize the renewable energy pyrolysis of coniferous residues in industrial conditions.
