Abstract

Numerous studies have proven that digital development positively affects economic growth. This study aims to confirm or refute the positive impact of digital evolution on economic growth by applying the dimensions of the International Digital Economy and Society Index (I-DESI). The analysis refers to the period 2015–2020 of the European Union member states. The study's novelty is that the I-DESI index has yet to be used in research to investigate the relationship between the digital transition and GDP production. The present study, therefore, goes one step further than the previous typical DESI-GDP models. The research uses Pearson correlation and F-statistic analysis to show the relationship between the variables. The study confirms that digital development has positively impacted the economic growth of EU member states. This result was confirmed by both Pearson and Spearman correlation. However, the results are ambivalent. The empirical results indicate that the more digitally developed member countries had a higher GDP per capita. However, the positive effect is different. The results confirm that the development of digitalization and GDP increased more dynamically in the more digitally developed EU member states than in the less developed member states. Therefore, an increase in the backwardness of the less developed member countries and not a catch-up can be observed in the period under review.

A miskolci Avasi Református Templom [3530 Miskolc, Papszer u. 14. hrsz.: 2405, azonosító: 2926, műemléki törzsszám: 848] nyugati falát egy kis méretű kerek, mérművekkel díszített ablak – rózsaablak – töri át, amit az 1980-as években kibontottak és újrafaragtak. A kőrestaurátori munkákról kevés feljegyzés áll rendelkezésünkre, így az eredeti ablak kőtöredékeinek holléte is ismeretlen volt. A rózsaablak kőtöredékeinek megtalálása, beazonosítása és konzerválása lehetővé tette bemutatását egy, a legutóbbi, 2019-es felújítási munkálataihoz kapcsolódó állandó építészettörténeti kiállításon a templom falain belül. Az esettanulmány a rózsaablak (ismert) történetét mutatja be az első ismert ábrázolásoktól, a Szehlo Ottó-féle téves felmérésen keresztül egészen a jelenkori állapotig; az ablak szerkesztésének elvi menetét, amely kontextusba helyezi a Sztehlo-féle vázlatokat és válaszol az ábrázolásokkal kapcsolatban felmerült kérdésekre; foglalkozik a kőanyaggal és a beépítési móddal, amelynek kiemelt jelentősége a kőrestaurálás folyamatában és a kiállításánál volt, hiszen a kőszerkezet állapota kritikus volt, egyes részei mozdításra törnek, kiállításához a szilárdítása és kezelése elengedhetetlen volt.

Abstract

This study highlights the effectiveness of the response surface method in predicting the properties of hardened concrete containing spent foundry sand and manufactured-sand. In current research, different mix proportions are prepared with spent foundry sand and manufactured-sand as partial replacements for fine aggregate. The workability, strength, and durability studies are conducted on all concrete mixes. The test results confirm that the inclusion of 20% of spent foundry sand is optimum for enhancing the strength and durability. Also, the inclusion of 20% of spent foundry sand in manufactured-sand concrete also possesses optimum results in strength and durability. Further, the response surface method has been employed to develop a model for compressive strength prediction. The R-squared and residual sum of squares of error for the compressive strength model were 0.9863 and 2.345, which confirms the goodness of the fit.

Abstract

Local scour poses a grave threat to bridge foundations, potentially causing catastrophic collapses. This study uses FLOW-3D with the Reynolds-Averaged Navier-Stokes model to analyze pier scour and dune formation under bridges. It focuses on submerged debris shapes near the water's surface. Results closely match experiments when specific conditions are met. The study introduces an innovative approach to debris impact assessment. Instead of traditional methods, it proposes a novel equation accounting for debris's effective area and elevation. This enhances reliability by over 20%, improving scour depth assessment in debris-laden scenarios. This advances the understanding of debris's role in local scour, benefiting bridge design and management practices.

Abstract

Present paper shows the different types of tensor product model based linear matrix inequality controller design and feasibility analysis of two degrees of freedom aeroelastic wing section model. The tensor product models are based on reducing or removing the nonlinear behavior of the system and weighting functions. The linear matrix inequality based method results globally asymptotically stable system. The goal of the paper is to examine that selecting and varying the transformation space influences the feasibility of the linear matrix inequality based controller. The paper gives a comparison between the different tensor product models in terms of controller performance. The linear matrix inequality gives feasible solution for the controller design if the transformation space is selected adequately.

This paper focuses on the reactions of three professors and architects (Jan E. Koula, Vladimír Karfík, and Alfred Piffl) to how the totalitarian political regime restricted and interfered with creative and academic freedoms in the period starting with the introduction of architectural education at the Slovak University of Technology and ending with the so-called “normalization” period in the former Czechoslovakia. All three of them were already active in interwar Czechoslovakia and thus had rich experience with working under democratic conditions, and their early work was influenced by the interwar avant-garde movements. After World War II, in part thanks to their pioneering work at the Slovak University of Technology, they got caught up in the system of the authoritarian socialist state. The central question that this study asks is how the trio dealt with the totalitarian regime, which stood in contrast with the democratic period of interwar Czechoslovakia that formed them as architects, and brought further limits to their work. Based mostly on material from their personal estates and period publications, we reveal how each of them found his own way to deal with the totalitarian regime, and we argue that even its limitations did not make Koula, Karfík, and Piffl abandon their beliefs and creative credos completely.

Az építőipar a munkaerő hiánya és az egyre fokozódó minőségi elvárások miatt a hagyományos, jellemzően emberi erőforrást alkalmazó vagy emberek által közvetlenül működtetett technológiák irányából apró lépésenként az automatizált technológiák irányába fordul. Az ezzel együtt járó változás csak úgy lehet zökkenőmentes, ha az építőipar résztvevői aktív részesei a változási folyamatnak. A cikk az építőipar fejlődési irányait, annak problematikáját és lehetőségeit kívánja bemutatni a területtel kapcsolatos kutatások és a már alkalmazott technológiai megoldások elemzésével a közeljövőben lehetséges változások, további lehetőségek, illetve problémák feltérképezésére és megvilágítására törekedve.

Abstract

Integrating thermal energy storage with thermal conversion systems is necessary to maximize their use. Phase change materials are the best media for storing and releasing thermal energy from various basic material types. Because the phase change materials have a high latent heat of fusion, it is often viable to use these characteristics and include the phase change materials in building envelopes to store thermal energy. The paper provides a thorough categorization of the phase change materials and thermal energy storage systems, in addition to an evaluation of their modeling using computational fluid dynamics. The purpose was to highlight computational fluid dynamics as a useful technique for advancing the engineering of thermal energy storage devices.

Abstract

This study evaluated the thermal performance of side divergence and uniform micro-channel heat sinks by comparing and contrasting them. Heat transfer and fluid flow characteristics in these micro-channel configurations were studied using computational fluid dynamics simulations employing ANSYS Fluent 2017 code for this purpose. Laminar flow through micro-channels with a Reynolds number of 207 was the subject of the investigation. The goal is to determine how side divergence affects heat dissipation efficiency concerning traditional uniform micro-channels. The results showed that the best divergence ratio is 1.5 that achieved the highest performance. The study also revealed that side divergence micro-channel heat sinks can achieve thermal performance up to 14% higher than uniform micro-channel heat sinks.
