E. Korcz Z. Kerényi László Varga

Publication Name: Lwt

Publication Date: 2021-08-01

Volume: 148

Issue: Unknown

Page Range: Unknown

Description:

The main objective of this study was to establish a correlation between total bacterial count (TBC) and exopolysaccharide (EPS) production in a specific Streptococcus thermophilus strain. TBC was determined based on real-time quantitative polymerase chain reaction (qPCR) standard curves of S. thermophilus T9 cultured in reconstituted skim milk. EPS yields were measured following isolation and purification steps using a dextran standard curve. The relationship between TBC of and EPS production by S. thermophilus T9 was analyzed alongside these standard curves. The results showed that EPS yield reached 36.6 ± 0.8 mg L−1 following 6 h of incubation. Over the same period, the streptococcal counts measured by qPCR increased from 4.71 ± 0.15 to 7.52 ± 0.09 log10 TBC mL−1. Overall, EPS biosynthesis has been shown to be a growth-related trait in S. thermophilus T9 (R2 = 0.991). In conclusion, the monitoring of TBC may provide an insight into the mechanism of EPS production and, therefore, its use can be recommended for this purpose and for EPS quantification. To our knowledge, this is the first research that has associated qPCR-based TBC with EPS yield in S. thermophilus.

THEORIES OF CULTURE-LED URBAN DEVELOPMENT: INITIATIVES IN DUBLIN

Tamara Zsuzsanna Böcz

Publication Name: Theoretical and Empirical Researches in Urban Management

Publication Date: 2025-08-01

Volume: 20

Issue: 3

Page Range: 41-58

Description:

This paper is exploratory research into the evolution of the theories and the practice of culture-led urban development. As cities and urban spaces have existed for centuries. Their purpose and functions constantly changing and evolving. With globalisation, numerous technological revolutions, and continuous innovations the demographical changes were often rapid to which swift adaptation was crucial. The ever changing and diversification of needs from the people inhabiting cities as well as global concerns led to new innovative approaches to urban development. One such approach is the idea of Creative Cities within which culture arose as a leading concern in the creation of urban development plans. This article will highlight some of the key areas and approaches on how culture can be utilised in urban development. The way in which creativity and culture is measured within the European Union. As well showcase the evolution of the culture led urban development approach of Dublin from the 1990s and finally examine the current urban development plans of Dublin and how they utilise culture in their plans.

Evaluating Fuel Consumption Rates Based on Rising Travel Demands Generated by Autonomous Vehicles

Balázs Horváth Dilshad Mohammed

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 553-558

Description:

Autonomous Vehicles (AVs) are anticipated to revolutionize the transportation sector by enhancing mobility and efficiency. However, the rise in travel demand resulting from increased accessibility and convenience may counterbalance the potential fuel savings associated with AVs. For this reason, this study examines the relationship between travel demand and fuel consumption, considering factors such as travel time, number of trips, and travel patterns. Through a combination of theoretical analysis and empirical data, the research aims to quantify the net effect of travel demand increment under varying demand scenarios using AVs on fuel consumption. The results showed that with the convenience of AVs, people may be more willing to tolerate longer commutes. This has led to an increase in Vehicle Hours Travelled, which directly translated to higher fuel consumption. These findings provide valuable insights for policymakers and stakeholders in designing sustainable transportation strategies and optimizing the energy efficiency of AV-based mobility systems.

Potential of Point Cloud Upsampling for Environmental Protection: Enhancing Airborne LiDAR Data for Sustainable Resource Management

K. Kozma Szeverin Oláh Árpád Barsi

Publication Name: Chemical Engineering Transactions

Publication Date: 2025-01-01

Volume: 121

Issue: Unknown

Page Range: 91-96

Description:

High-resolution, dynamic geospatial data support sustainable infrastructure, optimize urban services, and improve the quality of life of residents. Airborne Laser Scanning is an increasingly popular remote sensing technology that can be used to collect very large datasets of 3D point clouds over extensive areas, including forests, river basins, coastal wetlands, and mountainous regions. These datasets facilitate the analysis of vegetation structure, biomass estimation, hydrological modeling, and land cover detection or change monitoring. However, Airborne Laser Scanning-derived point clouds are typically limited to low density and spatial resolution, which preclude meaningful analysis for fine-scale ecological and environmental modeling. Point cloud upsampling is a permissible way to augment the spatial robustness of Airborne Laser Scanning point cloud data, and does so without adding a logistical burden of the data acquisition in the field, or the need to resurvey at high costs and time. Upsampling is synthetic in nature, achieving increased data point count, but maintaining dimensional integrity for continuity of surfaces and geometric fidelity, which is essential in methodologies that intervene for derived products such as digital terrain models, canopy height models, and vegetation metrics. This manuscript examines using point cloud upsampling as part of environmental monitoring. It reviews the upsampling algorithms that have been developed to date, synthesizes existing methods, and considers their relevance to the state of practice in forestry, watershed management, and conservation planning. The work considers and focuses on methodological bases for robustness and dimensionality, and although considerably nuanced, the methodological efficacy is subtended and suggests how enhanced points improve outcomes for ecological models and the information provided supports resource management decisions related to resource and sustainability decisions.. Ultimately and conclusively, the work establishes the understanding of point cloud enhancement for its visualization, but also its potential as an emergent action that contributes to construction and promotes a sustainability intention in environmental science and policy. This article appears as a mini-review. This writing aims to synthesise existing knowledge and conceptual strategies, rather than a novel outcome of an experiment. It is written to give an overview of existing methods and structured conceptual frameworks for employing point cloud upsampling techniques in the environmental monitoring and sustainability context. The review reiterates the conceptual soundness of point cloud upsampling in the workflow of environmental monitoring. The proposed framework reinforces the benefits of greater data richness and decision-making based on sustainability, without assuming new costs for data generation.

Cogging Torque Analysis of Toyota Prius 2004 IPMSM Motor with the Digital-Twin-Distiller

Mihaly Katona Péter Kiss Tamas Orosz Krisztián Gadó

Publication Name: Lecture Notes in Mechanical Engineering

Publication Date: 2023-01-01

Volume: Unknown

Issue: Unknown

Page Range: 126-138

Description:

With the recent advancements of the fourth industrial revolution, many sensors are implemented into the products that collect the data and monitor their performance. The measurement data can be stored with the numerical models as a digital twin, and these can serve as a virtual replica of a physical object or process. These digital twins can improve the design and optimization process. The paper uses an open-source tool, the Digital-Twin-Distiller, which can encapsulate the realized finite element analysis of a model into a web application, which can be integrated easily into an optimization chain or any other business process. The paper proposes a numerical model and cogging torque analysis of an interior permanent magnet synchronous machine. The paper examines the effect of two parameters of the magnet groove shape on the cogging torque of the Prius 2004 motor model. It was found that the cogging torque of the motor is highly dependent on the shape of the flux barrier, even with minor changes. On the other hand, the wedge between the two magnets does not affect cogging torque much.

Evaluating the effectiveness of public finance used for social protection of internally displaced persons

Yuriy Bilan Halyna Mishchuk Natalia Samoliuk Halyna Yurchyk

Publication Name: Public and Municipal Finance

Publication Date: 2025-01-01

Volume: 14

Issue: 1

Page Range: 23-40

Description:

The increasing number of internally displaced persons (IDPs) in wartime Ukraine leads to growing problems in social protection funding. Under these circumstances, the evaluation of the effectiveness of public finance use is of increasing importance. The study aims to evaluate the effectiveness of public finance for internally displaced persons’ social protection, adapting the KPI methodology for analysis on the national level. The effectiveness is considered following the OECD approach as the extent to which the intervention achieved its objectives and results. At macrolevel of research, the integral indicator was developed based on indicators of input (financing of social protection programs), output (involvement of IDPs in social programs), activity (funding per recipient and multiplicative effect in GDP growth), mechanism (administrative costs for achieving results), and control (effectiveness of IDPs’ social protection compared to other demographic groups). Thirty indicators in total were used (e.g., budgetary funding allocated for housing assistance; budget expenditures on staff salaries of the authorities responsible for certain programs; coverage rate of unemployed IDPs receiving vocational training). The essential distance from the maximum level of expected results (1.0) allows concluding the low effectiveness in this area of public finance use: from 0.330 in 2020 to 0.668 in 2023. Gaps are evident in each direction, especially in input performance (the highest value did not exceed 0.370). The best results were achieved in housing funding and employment governance. The proposed approach is useful for analyzing gaps and identifying opportunities to improve the management of other social programs.

On possibilistic dependencies: A short survey of recent developments

István A. Harmati Robert Fuller

Publication Name: Studies in Fuzziness and Soft Computing

Publication Date: 2018-01-01

Volume: 360

Issue: Unknown

Page Range: 261-273

Description:

Carlsson and Fullér introduced the notions of possibilistic mean value and variance of fuzzy numbers. Fullér and Majlender introduced a measure of possibilistic covariance between marginal distributions of a joint possibility distribution as the average value of the interactivity relation between the level sets of its marginal distributions. Fullér et al. introduced the possibilistic correlation ratio, the possibilistic correlation coefficient and the possibilistic informational coefficient of correlation. In this paper we give a short survey of some later works which extend and develop these notions.
