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

This project is the design of the tourism service station in the coastal park, which not only meets the basic functional requirements of the park service station but also reconfigures the station space with the regional cultural characteristics of Qingdao. The design process is mainly conceived in five aspects: locality, landscape, identity, symbolization, and diversification. It integrates the cultural characteristics of Qingdao coastal tourism with the park landscape to create a tourist rest space with diversified experiences. The purpose of this paper is to explore the interface between the stations' design and the various links of the cultural tourism industry chain. The project will be created as the “Window of Qingdao” in Baisha River Park.

Abstract

The digital economy is increasingly seen as an essential cornerstone in developing national strategies and industrial policies to enhance national competitiveness. On the other hand, a realistic assessment of digital readiness is essential for developing appropriate policies. In our paper, we group the countries of the European Union (EU) using three different methods applied to a dataset consisting of the four main dimensions of the EU's Digital Economy and Society Index (DESI) in order to identify Europe's main geographical “fault lines” in terms of digital readiness. DESI is a composite index aggregating several digitalization-related indicators to benchmark the progress of digital transformation in each member state. However, our methods aim not to rank countries but to identify groups of countries that are close to each other. The three methods used in the paper are partially ordered sets (poset), Tiered Data Envelopment Analysis (TDEA), and cluster analysis, known from multivariate statistics. The three types of clustering show a high degree of similarity, indicating the robustness of the results. Another research question relates to the extent to which the digital development of the EU Member States corresponds to the economic development of the countries and core–periphery relationships. While we can observe a high degree of similarity between the more and less developed clusters in terms of digital readiness and the groups that can be identified in terms of economic development and institutional quality, we also notice some peculiar exceptions (which could provide examples of best practices).

Abstract

In the event of a flammable liquid, gas, or vapor release the first step is to identify the type of outflow, which can fall into two categories sonic or subsonic. The two types of outflows carry different flow characteristics, which effect on the extent of the potentially explosive areas. In case of subsonic outflow, a short jet is formed without turbulent flow conditions at low velocity, which appears more concentrated around the source of release. With sonic outflow, a high velocity jet is formed with turbulent flow properties, which can extend further away from the source of release. The simulations examine the lower explosion limit of the flammable medium around the vessel where LEL20% or LEL40%. In addition, high temperature methane gas release was also presented.

Abstract

This study aims to identify and establish the long-term fluctuation of the low flow in the Hornád River. Hydrological data of five stations was obtained from the Slovak Hydro-Meteorological Institute and used for the analysis aims to show the trends of low flow and variability of the outflow during the period from 1973 to 2020. To determine low water levels, the limit value of the flow corresponding to the 70% and 90% from the flow duration curve along with the higher ones, determined on the basis of daily values for the entire multiannual period, was used. The observed patterns of low-flow changes on the example of a mountain river can be a reference point for many different studies and model simulations for other rivers in Slovakia.

Abstract

This article is related to investigations of the capture hoods of the local exhaust ventilation. The purpose of the research: to increase the zone of action of local exhaust hoods and reduce the amount of air removed. It is equipped with two barriers for air: ring and cylindrical. The empirical dependences for air velocity determination near the suction zone are obtained. Graphs, chart and three-dimensional image visualizations of removed air jet velocity near capture hood with barriers for air are designed. The reduction of production energy consumption, material, and ventilation system maintenance costs due to the correction of the design of the capture hood are the main benefits of the new solution.

Abstract

There is currently no accurate calculation procedure for determining the lateral-torsional buckling resistance of trapezoidally corrugated web girders. Therefore, a detailed investigation is performed in the frame of an experimental and numerical research program at the Department of Structural Engineering of the Budapest University of Technology and Economics. Based on the previous experimental results, a numerical model is developed to be used to determine the lateral-torsional buckling resistance by using deterministic method. The effect of flange size, corrugation geometry and boundary conditions are investigated. An improved design method is developed for the determination of the lateral-torsional buckling resistance of trapezoidally corrugated web girders.

Abstract

Analyzing the capacity of a signalized circular intersection is an essential aspect of traffic flow management. With the increased number of vehicles at the intersection, it is preferable to examine ways to increase capacity without altering the existing geometric features. A signalized circular intersection on the national highway in Győr, Hungary, between 47° 40′ 43.7988″ N and 17° 39′ 37.6668″ E is chosen and analyzed for capacity enhancement. The survey is conducted using 360-degree cameras. The PTV Vissim software is then used to construct a model based on the current and projected vehicle counts, as well as the current and proposed options. The result shows that it is possible to increase the capacity of signalized circular intersections without altering the geometric features.

Abstract

The current work discusses optimizing the structural design of reinforced high strength concrete rectangular sections under design loads. Using a least-cost design criterion and minimal design variables, an analytical approach to the problem is devised. A nonlinear mathematical programming format for the formulation of the problem is among the things that are demonstrated. To demonstrate how the formulation can be used in line with the ACI 318-08 standard, several typical cases are given. The outcomes are compared to those obtained from existing design practice. The ideal solution demonstrates unequivocally that significant reductions in the anticipated absolute costs of the building materials to be employed are possible and without making significant changes, this method may be expanded to address other portions.

Abstract

This study evaluates future changes in M-day minimum and maximum discharges in selected river basins of Slovakia, which have been divided into four groups, i.e., western, central, northern, and eastern Slovakia. Four types of data were available for the analysis, i.e., observed mean daily discharges, modeled mean daily discharges using the rainfall-runoff model, and simulated mean daily discharges according to the climate scenarios. The Indicators of Hydrological Alteration program was used to estimate the M-day discharges.

The results revealed an increase in the M-day minimum discharges in northern Slovakia. Eastern and Western Slovakia show a decrease in M-day minimum discharges and an increase in m-daily maximum discharges by 2100.

Abstract

Under the background of modernization, the continuation and development of historical and artistic values of ancient villages are faced with many difficulties, and corresponding theories are needed to guide practice. Taking Baojing Village in China as an example, this paper studies and expounds on the strategies for the protection and development of ancient villages, establishes a coordination mechanism for all parties and provides experience for the difficulties faced by this field. In the past, most Chinese ancient village literature studies focused on the characteristic value, formation, and evolution of historical and cultural villages. However, the research on the integration and utilization of resources in historical and cultural villages still needs to be further deepened.
