Abstract
U-bending tests are the most common method to predict springback and are influenced by the process and geometrical variables in addition to material behaviour. It needs a numerical study at a high level with many variables to reduce try-out time and loop. In this study, the U-bending test of DC01 steel has been researched numerically and experimentally to govern the influential parameters. The numerical analysis was conducted using AutoForm-Sigma code. The die radius has an excessive influence on the change of flange angle than the punch radius, but the punch radius has the greatest influence on the variation of the sidewall angle. The coefficient of friction played a great impact on both flange and sidewall angle deviation and its influence grows stronger as the blank holding force increases.
Abstract
An assessment of the moisture regime of the external enclosing structures of the building with a layer of insulation on the outer and inner sides was carried out, considering the thermophysical characteristics of all materials of the outer wall of the building. It is shown that brickwork without insulation to preserve the estimated term of its optimal operation, requires taking measures to bring its thermal resistance to heat transfer to a standardized value or to arrange more intensive air exchange in the premises of the building. It has been proven that when designing residential and public buildings, the results of assessing the moisture regime of external enclosing structures and the building's energy indicators for compliance with current requirements are a very important criterion.
Abstract
In this paper, a parametric study is done with various removal and replacement materials to study the effectiveness of the removal and replacement method on the wetting depth in the expansive soil and the amount of differential heave caused by climate conditions and common irrigation scenarios for the southern region of Syria. Soil suction changes and associated soil deformations are analyzed using finite element codes, VADOSE/W and SIGMA/W. The paper concludes that the optimum thickness for replacement with high permeability soil should be at least 1 m. In addition, it concludes that replacing soil with a permeability coefficient lower than the permeability coefficient of the site soil contributes to a 56% and 79% reduction in total and differential heave, respectively.
Abstract
Retaining walls are typical geotechnical engineering applications analyzed extensively in the literature. However, the optimal design of these walls is still unsolved due to the optimization problem's complexity and the unrecognized best solver that can be used. Most similar works present a single optimizer for this problem. This work used six metaheuristics to formulate and solve the optimal gravity retaining wall problem design. The comparative study was achieved among particle swarm optimization, grey wolf optimizer, artificial bee colony, dynamic differential annealed optimization, fertilization optimization algorithm, and whale optimization algorithm. The problem and its results were discussed in detail within the respective sections.
Abstract
This paper describes a novel hybrid technique with fractional order PID controller (FOPID) for simultaneously controlling the humidity of indoor air temperature and the direct expansion (DX) air conditioning (A/C) system. The proposed hybrid system is a joint performance of the butterfly optimization algorithm (BOA) and adaptive network fuzzy inference system (ANFIS), hence forth it is called BOANFIS Technique (BOANFIST). The purpose of the proposed system is to disconnect the temperature and humidity control circuits. The proposed control is modeled and replicated on MATLAB platform and is assessed using existing systems. The statistical performance of the proposed and existing systems of mean, median and standard deviation is also evaluated. It reduces computational time up to 1.01 s and also reduces energy consumption to around 16.42 KWh/day. Furthermore, the simulation outcomes suggest that the proposed technique may efficiently and accurately obtain the optimal global solutions of the proposed technique compared to existing systems.
Abstract
In the recent trends of re-formatting the concept and definition of museums, the number of reached visitors is closely related to their interest in the collection and curatorial program and the quality of the museum buildings' physical spaces. Numerous studies have recently discussed the effect of spatial layout and topology in determining the pattern of visitors' movement, influencing their ‘path of cultural and educational experience.’ This research deals with the five current museums of Prizren in Kosovo. Direct observations and comparative analysis aim to provide factual data to assist museum managers, curators, and designers improve museum design solutions regarding space layout.
Abstract
The most flexible and reliable technological system is Wi-Fi, which is made possible by a wireless connection that transmits data using radio frequencies. Wi-Fi networks, however, encounter numerous issues related to power supply, availability, efficiency, and security as a result of the various access points. While relational waves describe the medical device, Wi-Fi radios produce radio waves that are very dangerous for patients. This document offers line-of-sight communication between the transmitter and receiver using LED technology. Li-Fi technology is a method that transmits audio data using LED light, which is faster and more efficient than Wi-Fi. Since it is practically ubiquitous, light can be used for communication as well. A cutting-edge technology called optical communication includes a subset called light fidelity. By sending out visible light, the Li-Fi device enables wireless intranet communication. This paper is an in-depth study and analysis of Light Fidelity (Li-Fi), a novel technology that transmits data at high speeds over a wide spectrum by using light as a medium of transmission. The research fields that are pertinent to Li-Fi networks are thoroughly analyzed and categorized in this paper: high speed data transmission, receiving, sharing, broadcasting through light in free space optical communication system by Li-Fi technology. In this paper, we followed some methods and developed a unique method to develop this study: VLC, OOK, a Lambertian discharge mechanism, LOS, NLOS, or a CMOS optical receiver. The proposed model tested transmits and receives audio, video, and other data, which is very high-rated and near the 2 GB/s range.
Abstract
The exhibition design of modern museums increasingly relies on the creation of space to display the unique intrinsic cultural quality and place spirit of the exhibition hall, and the exhibition space has become the focus of the design. The exhibition space has become the medium language for the dialogue between the display content and the audience, and the typical venue space presents the required information to the public. In the development process of the information age, display design complements other disciplines and provides a solid foundation for the research and development of space for pavilion design. Narrative design can help the public to seek emotional commonalities and spiritual touches when visiting museums, pursue the real experience of the scene space, and feel the atmosphere and situation created by the theme space.

Abstract
This paper investigates the role of “The Yellow Pavilion” intervention by Architecture for Humans in reclaiming Rexhep Luci Street as a public space and promoting urban interventions in Prishtina. The temporary structure was installed for a week to transform the street into a public space, and the paper presents the findings of its impact on the neighborhood and city. By examining the effectiveness of temporary interventions, the article highlights the benefits and limitations of tactical urbanism while also considering the potential for this kind of intervention to create social connections, promote community engagement, and revitalize urban areas. Ultimately, this research contributes to understanding the value of temporary public spaces in urban design and planning.
