Published: August 2024

Abstract
In order to analyze the influence of different initial conditions on the performance of the impactor in a new impact testing device with double-sided pressurization, a two-dimensional numerical model of the impact testing device is established. Numerical calculations are performed on the model by using CFD software, combined with dynamic mesh technology. The influence of the initial pressure on the velocity performance of the impactor is obtained, and numerical validation is conducted with the existing impact testing device. The results show that the impactor under double-sided pressurization can achieve a higher velocity close to the experimental data, confirming the effectiveness and accuracy of this method. The research findings are helpful for predicting the velocity of impactors in impact testing devices under laboratory conditions.
Comparative Analysis of Performance Between Window and Eco-Cooler to Achieve Thermal Comfort in Hot Humid Climate
Authors: Pratiwi Niniek , Attaufiq Muhammad Muhdi 
Published: August 2024

Abstract
The increasing global temperatures have led to a higher demand for energy to maintain thermal comfort. In 2018, air conditioning was found to be the largest contributor to energy consumption, accounting for approximately 62% of the total energy used, according to data from the Ministry of Energy and Mineral Resources. Consequently, energy-saving initiatives that focus on cooling systems can play a crucial role in global energy conservation efforts. One such initiative is the implementation of Eco-Coolers. This study aims to compare the effectiveness of Eco-Coolers and windows in reducing room temperature for thermal comfort in hot and humid climates using Ansys simulations. The research adopts a quantitative approach by simulating the Eco-Cooler and window models using the Ansys application, followed by descriptive statistical analysis. The Eco-Cooler simulation involves a model with a diameter of D1 = 50 cm and D2 = 25 cm, which is then compared to a window measuring 45 cm × 100 cm. The results of the Eco-Cooler simulation demonstrate a decrease in temperature in all rooms where the Eco-Cooler is placed, with a maximum temperature of 27.05°C. This represents a decrease of 0.65°C from the initial temperature of 27.7°C. In contrast, the window model exhibits an upward airflow pattern, resulting in a maximum temperature of 27.35°C. This indicates a temperature drop of 0.35°C from the initial temperature of 27.7°C. Previous research on thermal comfort in Gorontalo City has shown that discomfort typically begins at a temperature of 29°C, with the peak of discomfort occurring at a temperature of 33°C. Therefore, based on the simulation results, the temperature range of 26.65°C – 27.05°C achieved by the Eco-Cooler can provide a comfortable or neutral sensation for individuals.

Published: August 2024

Abstract
Native architecture plays an important role in designing a sustainable place. Old people learned from trial and error to accommodate the environment into their life. In this article, Lampuuk Beach is investigated in terms of the indigenous architecture conducted by the local people to get close to the sustainability concept. The beach is located in Aceh province which lies on the northern tip of Sumatra Island, Indonesia. It has been developed as a resilient coastal resort in Indonesia transforming from the radical traditional architecture of a recreation area into a modernist zoning-style layout. This phenomenon was generated by the Indian Ocean earthquake and tsunami in 2004. This research aims to identify the transition of coastal area changes in the last two decades and the challenges facing sustainability in Lampuuk Beach. The methodology is qualitative using a narrative architecture approach by illustrating the design characteristics of tourism facilities spreading along the coastal line, including cottages, restaurants, sitting areas, and the landscape overall. The data was collected from observations and interviews with local people. All data were elaborated on and interpreted to map the reform of the coastal tourism facilities. The result depicts the unfolding of the indigenous architecture of Lampuuk Beach transforming from recreational culinary areas into modern coastal tourism approaching sustainability, particularly in the resort sector. To conclude, the transition of native architecture in Lampuuk Beach demands coastal tourism facilities changes towards its sustainability.

Abstract
Informal settlements, commonly referred as kampungs, serve as integral components within the urban landscape of numerous cities. However, these settlements have significant vulnerabilities in relation to various urban difficulties, including but not limited to modernization, urbanisation, and other catastrophic circumstances. Nevertheless, there is a limited amount of study that specifically addresses spatial and physical concerns in the region of South Sumatra. This study seeks to examine the configuration and visibility of changes in Kampung Tuan Kentang, located in South Sumatera, Palembang, using the framework of space theory. The objective of this study is to restructure the spatial organisation of urban kampungs by means of enhancing connectedness and integration. The primary objective of this research is to address the physical and geographical challenges faced by Kampung Tuan Kentang, with the aim of enhancing the overall spatial quality and creating a more favourable environment. The current state of the structural network pattern in Kampung Tuan Kentang has characteristics of both a linear pattern and an organic spatial pattern, which are commonly observed in vernacular traditional settlements. The utilization of computational analysis is anticipated to function as a valuable resource for designers, urban designers, and urban planners in the evaluation of decision-making during the design phase. Additionally, it aids in identifying kampung areas that require future attention.

Published: August 2024

Abstract
This study delves into the intricate typology of Perak’s cultural landscape through a comprehensive geographical mapping analysis. In Perak, the cultural landscape is experiencing changes, especially in the land and typology due to the overwhelming development. As cultural landscape plays a substantial role in historical and heritage values, efforts in documenting and analyzing the landscape change remain significant. This study documented a series of spatial data layers focusing on geographical context to describe and map the landscape typology in Perak. The geographical context including; agricultural landscape, coastal landscape, highland natural landscape, and lowland natural landscape was used as patches for the spatial and landscape-based metrics analysis. The analysis adopted the overlaying mapping technique by the Geographical Information System (GIS) in modifying and verifying the secondary data mapping by the Perak Structural Master Plan year 2040. The composite trajectory analysis in this study contributes to a more comprehensive cultural landscape typology toward sustaining cultural heritage value in the near future.

Abstract
This article is formed from the experiences of the authors when observations occurred at Pasar Baru in Bandung, Indonesia. The experience is the essential part of the Lived Space perspective by Henri Lefebvre, and that is the right approach to studying the sense of place of Pasar Baru Bandung. This strategy intends to provide a different view of the distinct values and spirit of Pasar Baru Bandung through the numerous everyday activities in and around it. Answering the research objectives was optimized with the interview, visual data, and exploratory literature. The concept of lived space also can lead to a sense of attachment in those who visit Pasar Baru Bandung. Recognizing a place contributes to its sustainability, and the sense of Pasar Baru is an identity that is no longer seen by its appearance but includes experiences. This article provides another understanding of lived space through the experience in Pasar Baru Bandung. This article also provides knowledge about Indonesian local values to a wider audience.
Perception of park environment and its impact on aesthetic evaluation
Authors: Gatalska N 
Published: August 2024

Abstract
The synthesis of scientific works highlighted a fundamental difference in the methods and approaches used to investigate the aesthetic qualities of park environments involving respondents. A pivotal methodological question in studying the aesthetic qualities of park environments and their human perception lies in determining the research approach - whether natural or using substitutes such as photographs or virtual simulators. In the context of this study, an analysis was conducted to ascertain the correspondence between the perception of the park environment and the assessment of its aesthetic qualities under different survey conditions. The research established that the influence of park environment features on the aesthetic evaluation of landscapes significantly differs depending on the season and the method of research. Characteristics of the park environment noted by respondents, which are closely related to aesthetic evaluation, are positive associative features defining the overall psycho-emotional impression of the landscape. Seasonal changes in the park environment notably affect the perception of compositional characteristics, especially enhancing aesthetic evaluation during summer surveys conducted directly within the park boundaries. Substantial decrease in aesthetic evaluation is observed due to the mismatch between basic features and respondent preferences, a phenomenon independent of the research method employed.

Published: August 2024

Abstract
The paper presents current trends in the development of environmentally friendly building composite materials. The choice of thermoplastic polymer binder and natural plant-based fillers is substantiated. Highly filled composites based on secondary polypropylene and natural plant fillers have been developed: wood flour; coniferous flour; buckwheat husks; oat husks. Their main physical and mechanical properties, such as impact strength and flexural strength, have been studied. Experimental research has revealed that, in addition to traditional fillers like wood flour and coniferous flour, it is more relevant to use by-products of agro-industrial complexes in the form of buckwheat husks and oat husks. These technological waste products of agro-industrial complexes are quite widespread in Ukraine and are widely available in almost all regions of the country. However, their disposal is usually challenging. For the first time, the influence of the fractional composition of plant fillers in polymeric composites based on secondary polypropylene on the main physical and mechanical properties has been studied. It has been clarified that the developed composites with polyfractional compositions of plant fillers exhibit higher indicators. The high performance of the composites is achieved due to the maximum packing density of natural fillers in the polymer matrix.
New research methods of electro-corrosion processes in concrete structures

Published: August 2024

Abstract
The paths of electric currents flowing through sleepers and traditional methods of corrosion under the influence of leakage currents are analysed. Based on the results of this analysis, a new method of studying the processes occurring in concrete under the influence of electrical potentials is proposed for comparative studies of the electro-corrosion behaviour of sleepers and other structures with steel and composite reinforcement. The method involves the application of electric potentials, constant or pulsating unidirectional, to the sleeper models and the study of samples extracted from the models using nanoindentation. By means of nanoindentation it is possible to obtain the values of the micromechanical properties of the cement paste, the modulus of elasticity E and the hardness H, which depend on the degree of its electromigration leaching. It is experimentally proved that due to electromigration leaching, E and H decrease, starting from the face of the model, for which a negative potential is applied. The values of unleached and maximally leached cement paste with W/C = 0.35, which is characteristic of concrete sleepers, are determined. It is found that the nature of these dependencies and, consequently, the intensity of electro-corrosion processes in concrete, depends on the nature of the applied electrical potential (constant or pulsating unidirectional) and the type of reinforcement (steel or composite).

Published: August 2024

Abstract
This paper explores the potential for implementing digital twin technology, focusing on the internal structure of the research object and the remote characteristics of its surrounding environment. Specifically, it examines and demonstrates the practical application of local digital twins, which replicate the object’s structural parameters using data from sensors and measurement devices positioned at key nodes within the research object. Another category of digital twins leverages data collected from instruments measuring external environmental conditions and falls under the classification of remote digital twins. When combined, these local and remote digital twins create a comprehensive framework for predictive decision-making, assessing both the current status of the object and potential outcomes in emergency situations. This study seeks to explore the feasibility of integrating digital twins across various hierarchical levels of the research object. The findings presented in this paper represent the authors’ practical innovations, which demonstrate effective outcomes and offer a foundation for advancing research objectives in this area.
Closed forms for spatiotemporal optical vortices and sagittal skyrmionic pulses
Authors: Vo S , Gutiérrez-Cuevas R , Alonso M A 
Published: August 2024

Abstract
Spatiotemporal optical vortices (STOVs) are short pulses that present a vortex whose axis is perpendicular to the main propagation direction. We present analytic expressions for these pulses that satisfy exactly Maxwell’s equation, by applying appropriate differential operators to complex focus pulses with Poisson-like frequency spectrum. We also provide a simple ray picture for understanding the deformation of these pulses under propagation. Finally, we use these solutions to propose a type of pulse with sagittal skyrmionic polarization distribution covering all states of transverse polarization.

Published: August 2024

Abstract
In this work, Ni-W-Ti2AlC composite coatings with anti-wear and anti-corrosion abilities were prepared using direct current electrodeposition. The study primarily focuses on the influence of different current densities on the structure and properties of Ni-W-Ti2AlC composite coatings. The microstructural, mechanical properties, and electrochemical performances were studied by using SEM, XRD, EDS, and Tafel polarization techniques. The results indicated that Ti2AlC is successfully co-deposited into the Ni-W coating, and the average grain size of the Ni-W-Ti2AlC composite coating is 15.2 nm. The significant improvement in hardness, wear resistance, and corrosion resistance of Ni-W-Ti2AlC composite coating is attributed to the effects of solid solution strengthening and the uniform distribution of the microstructure. The suitable current density has a great influence on the properties. The microhardness of Ni-W-Ti2AlC composite coatings was increased by 99.59% at a current density of 5 A dm−2 compared to 3 A dm−2. At the same time, the friction coefficient decreased by 13.89%.
ArtiSAN: navigating the complexity of material structures with deep reinforcement learning
Authors: Elsborg Jonas , Bhowmik Arghya 
Published: August 2024

Abstract
Finding low-energy atomic ordering in compositionally complex materials is one of the hardest problems in materials discovery, the solution of which can lead to breakthroughs in functional materials—from alloys to ceramics. In this work, we present the Artificial Structure Arranging Net (ArtiSAN)—a reinforcement learning agent utilizing graph representation that is trained to find low-energy atomic configurations of multicomponent systems through a series of atomic switch operations. ArtiSAN is trained on small alloy supercells ranging from binary to septenary. Strikingly, ArtiSAN generalizes to much larger systems of more than a thousand atoms, which are inaccessible with state-of-the-art methods due to the combinatorially larger search space. The performance of the current ArtiSAN agent is tested and deployed on several compositions that can be correlated with known experimental and high-fidelity computational structures. ArtiSAN demonstrates transfer across size and composition and finds physically meaningful structures using no energy evaluation calls once fully trained. While ArtiSAN will require further modifications to capture all variability in structure search, it is a remarkable step towards solving the structural part of the problem of disordered materials discovery.

Abstract
Climate-sensitive hazards, including extreme heat, wildfire smoke, flooding, and rising sea levels, can jeopardize the health of all populations. However, certain population groups are more vulnerable to harm from these hazards. While youth–particularly those from historically marginalized groups and communities–are among those at the highest risk, their abilities may be underutilized in local climate adaptation efforts. This exploratory research aimed to identify opportunities for youth involvement in climate and environmental solutions in their historically marginalized communities. Specifically, this study (1) investigated youth risk perceptions and impacts of various climate-sensitive hazards (e.g. extreme heat, wildfire smoke, flooding, and sea level rise); (2) examined current barriers, resource needs, and opportunities for youth to engage in climate and environmental solution work; and (3) explored current methods and spaces where youth and community leaders can support youth-led climate-related initiatives. Through focus group discussions with youth and in-depth interviews with community leaders who are directly with youth, this study identified opportunities to leverage youth experiences, perceptions, and assets to promote a healthy and resilient community in the face of various compounding climate-related threats. Results showed that while youth recognize the changing climate and associated health impacts, they require more financial resources and support from local decision-makers to maintain their engagement and promote community resilience. Engaging youth in climate action and community resilience involves more than just centering youth voices and perspectives–it requires intentional collaboration, capacity-building, organizing, granting decision-making power, and other strategies to produce inclusive, intersectional, and sustainable solutions.
Introducing the Major Players and Developing the Screenplay for a Fairy Tale Musical
Authors: Block Geoffrey 
Published: August 2024

Abstract
Chapter 1 tells the story of how Love Me Tonight came to be, starting with the search to find a film property for Maurice Chevalier, how Rouben Mamoulian came to be unexpectedly hired to replace Ernst Lubitsch, and Mamoulian’s meeting with the French playwright Léopold Marchand at a party. From the beginning, Mamoulian saw the intrinsic musicality of this story based on a play by Marchand and Paul Armont called Le tailleur au château (The Tailor in the Castle) and designed a musical with music at its center. Using treatments and screenplay drafts in the Mamoulian Collection housed in the Library of Congress, the chapter traces the initial creation and evolution of key dramatic events, plot developments, and character transformations, from the incomplete and sometimes tenuous first outlines and treatments to the final screenplay. The chapter also critically examines the reasons behind the decisions Mamoulian and his screenwriters made as they gradually placed the songs.
Sex and Censorship
Authors: Block Geoffrey 
Published: August 2024

Abstract
“Sex and Censorship” discusses the history, principles, and influence of the Studio Relations Committee during Love Me Tonight’s creation and first release in 1932 (before the introduction of severe film censorship) and its rerelease in 1949, when the Production Code Administration (in the popular literature often referred to as the “Hays” Code) insisted on the removal of several conversations about the “Virgin’s Spring,” the innuendo-rich “A Woman Needs Something Like That,” and about fifteen seconds of Myrna Loy singing a reprise of “Mimi” in a diaphanous nightgown. The chapter uses the extensive paper trail of memos between Paramount executives and PCA enforcers to explore the reasons behind the censors’ choices and the impact of these decisions, particularly those imposed upon the film’s rerelease. Although intrusive, the silver lining behind these cuts is that the amount of film material challenged in 1932 and destroyed in 1949 was far less than usually cited, probably a few minutes at most. Far more significant was what made it past the Code, both in 1932 and 1949.
