Discover the Latest Journals in Architecture and Architectonics
Architecture is both the process and product of planning, designing, and constructing a building or structure, while architectonics is the scientific study of architecture itself. Architectural works are often considered important cultural symbols and works of art, and we often identify past civilizations with their architectural heritage.

Abstract
Aircraft wings encounter multiple forces during flight, like thrust, drag, and abrupt variations caused by storms. Although these forces aid in maintaining overall stability, they can also cause the growth of cracks and expand over time, a process referred to as fatigue.
The resulting lift, drag, and pressure distribution on the wing have been analyzed using computational fluid dynamics in ANSYS. These loads were then incorporated into the wing model to evaluate the shear and equivalent stresses.
Cracks growing on the aircraft wing surface. The wing surface manufactured from AL2024-T3 alloy was investigated when subjected to non-preoperational multi-axial cyclic loading. This fracture mechanics analysis employed two methods: experimental calculation and Numerical simulations.
Abstract
An urgent problem today is the industrial production of biomethane using biogas plants from organic waste, which is environmentally hazardous to the environment. The purpose of the work is to substantiate the methodological approach to the formation of the raw material base for biogas production. Achieving this goal was carried out based on monitoring and assessing biomethane emissions into the atmosphere based on data from space satellites for various areas. The most significant results are the developed methodological approach to substantiate the raw material base based on indirect measurements of biomethane emissions during satellite sensing. Based on the use of this approach, a substantiation of a promising raw material base area was carried out.
Abstract
An analysis study was conducted to evaluate the effect of the transient groundwater table with and without impacts of seismic loads on stability of excavation nailed slope using Bishop and Janbu simplified methods. The results showed that the factor of safety values increased with increasing of the groundwater table depth and reached a relatively maximum level for each of the two methods of analysis when the groundwater table drops to the depths 18, 19, and 20 m. Also, the results indicated that the percentage of increase in the factor of safety decreased significantly, starting from depth = 13 m, and the differences converge greatly to the point of fading at depths 17 and 18 m and these findings support the notion that the presence of groundwater table in the upper layers of the excavation sides poses a greater risk and increases the possibility of collapse failure.
Abstract
Today, due to the increase in urban infrastructure, it is faced with the problem of overflowed waters. In urban areas, reduced rainwater infiltration increases the volume of wastewater in the sewer system, leading to water quality issues in the receiving bodies. Qualitative and quantitative analysis of overflowed waters can help reduce pollution in in the recipient. To do this, firstly it needs to analyze the quality of the water in the recipient and the quality of the overflowed waters during precipitation. By monitoring and analyzing water quality, it will be possible to apply protective measures to solve this problem.
Abstract
The main purpose of this paper is to design and model a sustainable water distribution network for the new housing development in Bernolákovo. WaterGEMS software and Microsoft Excel are used for the analysis and design of the water distribution network. The survey of the village was developed with the help of a global positioning system to ensure the layout and the satellite image of the study area. Steady-state analysis has been carried out for the calculation of hydraulic parameters. The analysis performed by the software is essential for identifying potential problems and performing quick diagnostics so that expensive errors can be avoided. The study results indicate that the proposed distribution network will provide high-quality drinking water in the required quantity.
Abstract
Current digital education operates as a push-system, despite the content and subject characteristics suggesting a need for a pull-system. One of the features of the push-system is a tool-centered approach, where the focus on tools, including both hardware and software, is the belief that it is possible to build knowledge inventory. The consequences of the push digital education approaches are that (1) the fundamental concepts of Computer Science are not being transferred, (2) the lack of the development of supporting methods, (3) and education does not seem to be interested in revealing the root causes and to be open for fundamental changes. This paper proposes the extension of the theory of the industrial pull systems to present as a potential solution to increase the effectiveness and efficiency of digital education and reduce or eliminate data processing inefficiencies generated by undereducated but misled end-users. In addition to theoretical discussions, it also delves into the detailed analysis, design, implementation, and testing of a real-world data processing problem. The presented problem, its analysis, solution, and accompanying discussion reveal how one of the tools (kanban) of lean production can be adapted to support the Just-in-Time philosophy in digital education, focusing on end-user programming.
Abstract
As of today, oil and gas wells are 6,000 m deep or more. In view of this, increased requirements are imposed on the grouting materials used in wells. Grouting fluids must have rheological properties with low values of dynamic shear stress (τ) and plastic viscosity (η). Reducing the values of τ and η will provide a turbulent flow regime of cementing fluids, which is favourable in terms of complete replacement of the washing fluid with the cementing fluid. In the course of the research, it was found that the Melamine-Formaldehyde Anionic-active Resin superplasticiser is a reagent that has a multifunctional effect on cementing dispersions. This makes it possible to use it in difficult geological and technical conditions for well cementing.
Abstract
This research highlights the role of sustainability aspects focusing on socio-cultural parameters and environmental performance in designing more comfortable and sustainable shelters. Following a two-mixed method approach, on the one hand, a comparative analysis is presented of IKEA Better Shelter, Rwandan Mud-Brick, and Nepali shelters by examining the cultural integration into their design (traditional layouts and shared spaces), their adaptability, and their environmental performance. On the other hand, a qualitative survey determines the level of satisfaction regarding space, comfort, social interaction, and cultural fit among residents. The results show that traditional building methods with the use of local materials, offer high privacy levels, excellent thermal and acoustics comfort, good cultural appropriateness and minimal environmental impact.
Abstract
The hydraulic gradient method is an effective approach for localizing hidden leaks in water supply networks. Relative errors in leakage location depend significantly on head measurement errors, necessitating the use of high-precision pressure gauges with an accuracy class of 0.25 or better. An optimization function, defined as the ratio of the localization relative error to the probability of detection, was used to determine the optimal location for the control section. Dependencies of localization relative error on the pressure gauge accuracy class, section length, and piezometric head are obtained. Presented multi-leakage estimation model enables the assessment of the multi-leakage probability, enhancing decision-making efficiency for emergency repairs in water supply networks.
Abstract
Energy strategies at the international level increasingly support the utilization of hydrogen for energy purposes. One way to do this is to mix hydrogen into natural gas, which is delivered by the network to the combustion equipment of consumers. The paper examines the expected changes that will occur if the maximum amount of hydrogen permitted by law is mixed into the natural gas network. According to our results, the inflowing heat quantity in the gas has decreased, which is compensated by the increased flow rate due to the reduced density. The flame image changes spectacularly, the flame becomes lower, the half-cone angle increases in case of hydrogen mixing. Another noteworthy result is that the temperature of the equipment's burner did not change significantly as a result of mixing.
