Abstract

Today, the role of humans is changing rapidly in both industrial production activities and services. Mediocre, easy-to-learn activities can be performed more efficiently by machines; mediocre knowledge is being devalued while the importance of high-level skills is increasing. As a result, in all sectors of the economy, and especially in engineering, new approaches to expert training are needed; people must learn to hand over certain decision-making roles and to control the processes supported by AI rather than compete with it. STEM education has a responsibility to achieve these goals and must develop appropriate tools for engineering education. This paper presents a complex didactic methodology for competency-based education in engineering bachelor programs. An important element is the mathematical competency map, which shows the importance and place of mathematical and algorithmic (coding) knowledge in engineering topics. Another element is the systematic testing of mathematical knowledge in non-mathematical contexts in engineering courses. We provide an overview of our achievements in applying the developed toolset and improving the efficiency of mathematics teaching in engineering bachelor programs.

Abstract

Using finite element methods, residual stresses were estimated in pipe welds. Experiments were also conducted to verify the numerical results. An alternative to a three-dimensional model was used to simplify the numerical calculation for residual stresses investigation. Model predictions were validated by measuring residual stresses using X-ray diffraction. As compared to measured residual stress distributions, the computational approaches developed in this study can accurately predict welding residual stress distributions. The focused welding parameters have a significant impact on residual stresses even when all the other parameters are the same.

Abstract

The predictive maintenance of permeant magnet synchronous motor is highly required as this kind of motor has been commonly employed in electric vehicles, industrial systems, and other applications owing to its high power density output, as well as the regenerative operation characteristics during braking and deceleration driving conditions. One of the most important causes of PMSM failure is the stator short and drive switches failure. These problems have attracted more attention in the field of deep learning for fault detection purposes in the early stages, to avoid any system breakdown, and to decrease the risk and price of maintenance. In this paper, we investigate the possibility of detecting the electrical faults in PMSM by generating our data which includes current signals that have been analyzed and preprocessed by applying Continuous Wavelet Transform (CWT) to select the reliable features this conversion will be used to train ResNet 50. The evaluation metrics have shown that ResNet 50 achieves an accuracy of 100% for the classification of faults.

This research investigates the effect of incorporating innovative human hair fibers (HHF) and polypropylene fibers (PPF) into concrete, which has been observed to enhance the material’s strength characteristics. These fibers augment the concrete’s tensile strength and resilience, fortifying it against cracks and elevating its overall endurance. This research delves into the impact of reinforcing concrete specimens with human hair and polypropylene fibers. These specimens are employed in cube, cylinder and flexural beam tests. Both fresh and hardened properties, such as compaction factor and slump, and compressive, split-tensile, and flexural strength at varying curing periods (28 days and 90 days) and the ratios (1%, 2%, and 3%) are considered by weight of cement. Specifically, the 3% polypropylene fiber concrete mix exhibited the highest average compressive strength at both 28 and 90 days, while the 2% polypropylene fiber mix showed the highest split-tensile strength. Flexural strength results followed a similar trend. Results show that 3% HHF addition leads to notable improvements in concrete strength properties, albeit not as significant as with polypropylene fibers. Statistical analysis, including independent samples Kruskal–Wallis tests, was conducted to compare the distributions of strength values across different groups. The statistical analysis indicates significant differences in strength distributions across groups, with p-values below the significance level of 0.05. This underscores HHF’s potential as a sustainable alternative in construction applications, contributing to enhanced concrete strength.

Abstract

The integration of Autonomous Vehicles (AVs) into our modern society hinges on gaining widespread acceptance from potential road users. To indicate the preparedness of these road users and elucidate their perspectives regarding the use of AVs in future, it is imperative to conduct surveys gauging public acceptance and satisfaction with this emerging mode of transportation. This paper reports the results of a comprehensive questionnaire study involving 1,000 individuals in Gyor City. The survey's primary objective was to assess participants' attitudes and willingness to embrace autonomous vehicles within the city's road networks. The study delved into various socio-demographic factors, such as age, gender, and employment status, while also exploring participants' prior knowledge and opinions regarding the advantages and limitations of AVs. The findings reveal a generally favorable disposition among the public toward the inclusion of AVs in urban traffic, paving the way for the acceptance of mixed traffic patterns. Notably, respondents in younger age groups exhibit greater enthusiasm for incorporating AVs into their daily transportation, whereas individuals aged 65 and above express more reservations, displaying a conservative outlook. Furthermore, participants with prior knowledge and a deeper understanding of AVs exhibit a markedly more positive inclination toward this emerging technology compared to those lacking such familiarity.

This article presents an objective, point-cloud-based geometric description of the nave, apse, and sacristy vaults in the fortified church of Mediaş (RO; Medgyes, Mediasch). The description includes the global geometry of the rib systems and the connections between the webs and ribs in each vault. Based on these, we classify these structures into the geometry-based typologies for the global geometry of the rib system and the rib-web connections we established based on our previous works. Additionally, based on the vaults of Mediaş, two rib-system subtypes have been defined: centralising and linear vaults. The relationship between these subtypes and the concept of cylindric and spheric vaults, as well as their connection to the ‘pattern’ of the net vaults is discussed. Based on the geometric descriptions, we also discuss the possible building strategies and techniques of these vaults and consider the periodisation of the building.

Abstract

Design and testing of real materials is a costly process and usually requires some specific equipment. To alleviate this task numerical methods can be leveraged. In this work we show possible modelling technique for closed-cell material structure using Weaire–Phelan unit cells. As an example existing aluminum structures were used and modelled parametrically, allowing to establish different geometrical models for different applications. Numerical simulations for compression was also done on the developed models to reveal the material response. The influence on the cell wall thickness and the friction between the material and the compression plate was investigated. It was found that the friction coefficient has no significant effect on the material response, except in the case where bonded connection was assumed. It was also demonstrated that material response and the porosity controlled by cell wall thickness have an approximately linear relationship with each other. This method proved to be a flexible and alternative solution of real laboratory tests and targeted to reduce costs of material design.

Típus-lakóépületek Magyarországon

Standardised Residential Buildings in Hungary

Az elmúlt ötven év során sok iparágban, például a ruha- és a bútoriparban, az egyedileg tervezett és gyártott, kisszériás áruk helyét egyre inkább a sorozatgyártott tömegtermékek vették át a fejlett országokban. Mivel a sorozatgyártás lehetőséget biztosít a termékek optimalizálására, azok sok esetben olcsóbbak és kiszámíthatóbb minőségűek lehetnek, mint az egyedi termékek. Ez pedig egy megfelelően széles választék fenntartása mellett kifejezetten vonzó a vásárlók többsége számára.

Bár az építőipar más iparágakhoz képest lassan fejlődik, az épületelemek előregyártása egyre jellemzőbbé válik Európában a szakképzett munkaerő hiánya és a helyszíni kivitelezés kockázatai miatt. Egyelőre ugyan a legtöbb épület még egyedi tervek alapján születik, de az előregyártás terjedésével, a nagy fejlesztő cégek térnyerésével és a lakáspiac drágulásával kérdéses, hogy a lakóépületek meddig lesznek képesek megőrizni az egyediségüket vagy egy hasonló folyamatnak leszünk hamarosan a szemtanúi, mint ami a ruha- és a bútoriparban lejátszódott.

Mivel az épített környezettől elvárt egyediség összefügg az ember megélt tapasztalataival, a felvázolt jelenség apropóján a jelen cikk azt vizsgálja, hogy Magyarországon milyen motivációk álltak a formai szempontból egynemű lakókörnyezetek létrejöttének hátterében. A példák felsorolása mellett a cikk felvázol egy keretrendszert, amin belül értelmezhetővé válnak azok a társadalmi folyamatok, amik megmagyarázzák, hogy miért és miként építünk típusépületeket. A javasolt rendszerezés szempontként vonja be a típusépületek elemzésébe, hogy ezek az épületek fentről lefelé vagy alulról felfelé építkező folyamat eredményei-e, elterjedésük projektspecifikus-e, és hogy maguk az épületelemek szabványosítottak-e.

A jelen cikk a körülöttünk lezajló folyamatok értelmezésén felül egyfelől bemutat példákat arra, amikor a típusépületek használatával harmonikus épített környezet jön létre, másfelől pedig bemutatja azt is, hogy milyen okok állhatnak amögött, amikor a típusépületek nem válnak be. Mindez segíthet abban, hogy elkerüljük a jövőben az olyan épületek sorozatgyártását, amelyek borítékolhatóan nem lesznek képesek hosszú távon is megőrizni társadalmi elfogadottságukat.

Abstract

The immediate vicinity of buildings of different floors causes damages of the smoke and ventilation channels work of the low-rise buildings. This is dangerous for the resident's health and lives. To determine the impact of high-rise buildings on the operation of air channels of a nearby two-story building, experimental research has been carried out in a wind tunnel. Charts and analytical formulas have been designed for determining the buildings aerodynamic coefficients depending on wind directions and the channels height. An increase of the channel height results in an increase in static rarefaction in smoke and ventilation channels. Increasing rarefaction increases the efficiency of the natural ventilation system and ensures the residents health and life.
