Abstract

With the gradual improvement of urban construction, more and more experts and the public realized that the speed of urban development be reasonable, which caused urban regeneration to turn to a new-minded “urban micro-regeneration”. “Micro-regeneration” is an extension of the concept to the direction of urban construction. The concept of micro-regeneration was first applied to the regeneration of individual buildings in the old city. The research on the intervention of public art in urban micro-regeneration is still in its infancy in China. Based on practice, this paper explores the possibility of public art's intervention in urban micro-regeneration.

Evolution and Cyclicality in Rural Tourism •

Experience of Tourism Development in the Inner-Őrség in the Light of Statistical Data

Fejlődés és ciklikusság a vidéki turizmusban •

A Belső-Őrség turizmusfejlődésének tapasztalatai a statisztikai adatok tükrében
Építés - Építészettudomány
Authors: Ágnes Bertyák and Kornélia Kissfazekas

Tourism is one of the fastest-growing economic sectors in the world, and any settlement that can harness and promote its potential can benefit from it. It is not only the prerogative of cities but can also make a significant contribution to the survival and development of smaller settlements.

The development of tourism in a given area is not a sudden, rapid process, but usually takes place over several decades, through cyclical phases. Our research is based on the different hypothetical models of the stages of tourism developed by Noronha (1977) and , the applicability of which was examined in rural areas through the example of the Inner-Őrség. Nowadays Őrség (Guard’s Country) is one of the most popular tourist destinations in Hungary, where the small settlements of the area have built on their natural, architectural and cultural assets and they have been able to exploit their potential by using the right marketing techniques. The villages of the Inner-Őrség have developed at different rates since their discovery as tourist destinations, and depending on their role in the settlement network, their accessibility and tourist values, the different phases of tourism development took place at different speeds in their territory. Therefore, the intensity and impact of tourism varies in each village despite the strong interaction between them.

In the present study, we seek to identify the trends and characteristics of the development of tourism in the examined area by using the results of the available statistical data, in order to obtain a more accurate picture of the role of tourism in the settlements concerned.

Abstract

Identification of online hate is the prime concern for natural language processing researchers; social media has augmented this menace by providing a virtual platform for online harassment. This study identifies online harassment using the trolling aggression and cyber-bullying dataset from shared tasks workshop. This work concentrates on extreme pre-processing and ensemble approach for model building; this study also considers the existing algorithms like the random forest, logistic regression, multinomial Naïve Bayes. Logistic regression proves to be more efficient with the highest accuracy of 57.91%. Ensemble bidirectional encoder representation from transformers showed promising results with 62% precision, which is better than most existing models.

Abstract

Timber is a widely used material in construction. The moisture content has a significant impact on the mechanical and physical properties of it. This paper studies how the moisture content values are directly connected to the climate conditions, especially temperature and relative humidity, by measuring these factors for a non-renovated historical timber roof for a one-year period, combined with meteorological data for Pécs since 1901. The fluctuation in moisture content values created instability in the water content of the structural elements due to absorption and release of water in order to reach the equivalent moisture content point. This process led to continuous volume increase-decrease of the timber, thus to formation of cracks, discoloration and harmful fungi development.

Abstract

The comparison of Mono and Multi Repository structures is a highly debated topic in the software development field. Despite the choice of repository structure is the first main step in development; so far, this comparison has only been made on a small or local scale. Here, Mono and Multi Repository structures have been compared from different aspects using thousands of projects.

First, an algorithm shared for collecting and identifying Mono and Multi Repository projects and save them into the database. Database was used for making different comparisons for example the usage intensity of both structure types over time, the developer's preference over structure type based on their country and so on. Also, all these comparisons have been made according to the team size and development period for each repository structure.

Abstract

Two different tire configurations consisting of a dual tire and a super single wide tire having different range and distribution of contact pressures have been analyzed. Along with the effect of speed on development of pavement damage at speeds of 5, 50 and 80 km h−1 under zero and uniform wander modes. Results show that at super slow speeds of 5 km h−1, at dual wheel moving at zero wander mode, decrease in fatigue life of the pavement is 3.5 years, which is 1.45 times more than the dual wheel moving at uniform wander and 3.4 times more than wide tire moving at uniform wander mode. The difference between fatigue damage at different lateral wander modes is prominent at speeds greater than 50 km h−1. A wide tire performs better than the dual wheel under zero wander configurations.

The Relationship Between Theory and Practice •

Design Works of the Faculty of Architecture at the Budapest Technical University in the 1950s
Építés - Építészettudomány
Authors: Rita Karácsony and Zorán Vukoszávlyev

The article examines the relationship between theory and practice through the history of architecture education, considering the possibilities of the 1950s from the perspective of teachers and students. This period may be the subject of separate research for two reasons. On the one hand, at the turn of the 1940s and 1950s, private offices were replaced by large state owned design institutes, and so professors could no longer pursue independent design activities in addition to education, although not long ago the two were even more physically intertwined as they could operate their offices within the university departments. The other that may have attracted interest in the early 1950s is the emergence of the socialist realist style dictatorship, to which education also had to adapt. The importance of practical experience for design instructors was recognized from all directions, so a solution was soon found: as a working community of design departments in the faculty of architecture they were invited to apply for large-scale design competitions or they were contacted directly. The study lists the departmental works published in the journal Magyar Építőművészet recently and presents the current architectural tendencies through them, which also had a clear effect on the education at the Technical University. In the following topic we deal with the possibilities of the students, since in the education system of architecture, in addition to the acquisition of theoretical knowledge, the widest possible expansion of practical knowledge has been of great importance – both in the past and today. Students could also take part in certain departmental tasks, or in design competitions, working with a special permit, and all of them were obliged to participate in the summer practical construction camps from 1951 onwards. With the help of personal recalls, we also look at how satisfied the teachers and students were with their tasks outside the university – so the archival and literature sources are supplemented with personal points of view.

Abstract

The design of supported embankments on soft soil is a common challenge for civil engineers. This article aims to evaluate the performance of three advanced constitutive models for predicting the behavior of soft soils, i.e., hardening soil, hardening soil model with small-strain stiffness, and soft soil creep. A case study of a rigid inclusion-supported embankment is used for this purpose. Plaxis 3D program was adopted to predict the settlements in subsoil layers and vertical stresses in the load transfer platform. Comparison between field measurements and result of Plaxis 3D modeling was performed. Results demonstrate that soft soil creep model yields predictions in a good agreement with the field measurements, while hardening soil small strain model gives slightly worst predictions.

Abstract

Wind generation is regarded by many as the future of renewable energy source, but the difficulty of recycling end-of-life wind turbine components could create another kind of environmental pollution. Either landfill or incineration of end-of-life wind turbine components will cause environmental hazards. However, the current recycling technology is immature and economical. Make clean energy ‘cleaner’! The recycling of end-of-life wind turbine rotor hub and blades has become a new goal and task for architects and designers. This article uses a real project reconstructed by end-of-life wind turbine components to demonstrate the positive role of spatial narrative in achieving low-carbon and sustainable design.

Abstract

The floodplains of the Tisza River, stretching across the eastern part of Hungary, are often affected by riverine and inland excess water flooding and draught. This paper investigates a possible solution to this problem utilizing the water retention capabilities of old floodplains. In this study, the effect of the position of the inlet structures of a floodplain, near Csongrád town, was examined with HEC-RAS 1D-2D coupled model. Based on the results, the rules of the deep floodplain selection were determined. On the extended model, the possibilities of a deep floodplain storage area chain have been explored. According to the estimate, more than 2.36 km3 potential storage capacity is available along the Hungarian section of the Tisza River.
