Financial Innovations for the Sustainable Development of Smart City Infrastructure

Gábor Gyura Barbara Eszter Huszár

Publication Name: World Sustainability Series

Publication Date: 2026-01-01

Volume: Part F1269

Issue: Unknown

Page Range: 31-53

Description:

The transition towards smart cities necessitates innovative and sustainable financial models that integrate technological advancements with long-term economic viability. This study explores the role of financial innovations, including blockchain-based funding, green bonds, and decentralized finance (DeFi), in supporting the sustainable growth of urban infrastructure. Traditional financing mechanisms often struggle to accommodate the rapid evolution of smart city initiatives, making innovative financial instruments essential for ensuring both economic and environmental sustainability. The research is based on a comprehensive literature review and case studies from leading smart cities such as Singapore, Amsterdam, Barcelona, and New York. Blockchain technology facilitates transparent and automated financing through smart contracts, while green bonds and other ESG-focused instruments enhance private sector participation in sustainable urban projects. Crowdfunding and tokenization further enable community-driven investments in smart infrastructure, strengthening citizen engagement and financial inclusivity. After analyzing these innovative financial instruments, the paper aims to propose a simple model to help identify which instrument is best suited to a city’s transition, considering its specific geographical, social, and economic context.

Embedded System Simulation Using Renode †

Istvan Szalay Ferenc Péter Speiser Denes Fodor

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

In the automotive industry, the reduction of development costs is of key importance. The development of electrical hardware is an expensive, time-consuming process with a lot of development stages (e.g., prototyping, electrical testing, mechanical testing, lifecycle testing). There is a growing need to increase the cost-effectiveness of the development and testing phases of embedded software using virtualization. Using this method, less prototype manufacturing is necessary since the simulations allow for faster and more effective discovery of a large portion of possible faults without building a hardware prototype. Renode is an open source embedded system simulation framework that facilitates software-based testing. The main goal of this paper is to explore the usability of the framework for automotive applications.

Pavement Sustainability Implications of Different Lateral Wander Modes for Autonomous Trucks

Csaba Koren Richárd Nagy Mohammad Fahad

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 631-636

Description:

Autonomous trucks can bring changes in transport infrastructure in terms of sustainability based on the type of lateral wander mode used. In this research, two lateral wander modes, a zero wander and a uniform wander mode, are analysed based on their applicability for sustainability in terms of CO2 emissions. Life cycle analysis has been performed for the analysis period of 30 y for the pavement section of 10 km, along with fatigue predictions. Results show that zero wander mode generates more emissions as a result of premature fatigue damage under channelized loading. The uniform wander mode yields 20 % fewer emissions. Moreover, the use of full-depth reclamation during the pavement's Life Cycle improves the CO2 emissions by 15 % when compared to traditional removal and reconstruction methods. Therefore, the uniform wander mode is favourable for the improvement of pavement sustainability in terms of CO2 emissions.

An expert system for the cost-optimal refurbishment of buildings

Árpád Csík

Publication Name: Advanced Materials Research

Publication Date: 2014-01-01

Volume: 899

Issue: Unknown

Page Range: 599-604

Description:

In the present paper we propose a solid theoretical framework for the automatic parametrization of the cost-optimal refurbishment of arbitrary buildings. The parameters describe the structural parts of the building that can be modified or replaced during the refurbishment process. The methodology also provides the cost-optimal refurbishment cost and the corresponding smallest possible total life-cycle operation cost constrained by the available technological and economical limitations. The theory is implemented into the EnergOpt expert system providing fast and accurate answers to costoptimization problems appearing in common practical applications. The system is built on firm mathematical foundations that is supported by state-of-the-art optimization algorithms capable of finding good optimums in a short amount of CPU time. The modular structure of the IT implementation facilitates effortless localization in different countries. The application of the system may considerably contribute to the decrease of the heating energy consumption and the corresponding environmental load of the building stock. The practical potential of the technology is demonstrated by the energetic analysis of an existing family house. © (2014) Trans Tech Publications, Switzerland.

Personal Watercraft Remote Control Communication Fault Detection †

Ádám Titrik

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

Hydroflight is a watersport where the user utilizes a waterjet-propelled backpack to fly over water. These backpacks are usually powered by purpose-built equipment but can also be propelled by personal watercraft. To have full control over movement during hydroflight, the user needs to adjust the throttle of the watercraft, which is commonly performed by converting the system to remote-controlled operation. However, care should be taken during conversion to ensure safe operation and avoid harm to the user. This paper presents a failure analysis of sudden safety mode activation on a personal watercraft converted to remote control for hydroflight applications, as well as actions taken to avoid full shutdown in the case of communication loss, without compromising user safety.

Publication Name: 11th IEEE International Conference on Cognitive Infocommunications Coginfocom 2020 Proceedings

Publication Date: 2020-09-23

Volume: Unknown

Issue: Unknown

Page Range: 425-430

Description:

Result of modern digital age, the concept of Personal Learning Environments (PLEs) are becoming more relevant in today's academic world. Personalization is needed to make a product or service or an educational environment more endearing to the target audience, and this is especially true for VR Learning. The paper examines the learning effectiveness connecting to the personalized learning content with the participation of 90 students. The personalized VR education was based on an examination of students' learning type and attribute. In the experiment, the same curricula is compared when executed using audio, visual or reading type of learning content. To determine the learning style of students, the Kolb's learning test were applied. Tests show that the users were able to complete the tests with at least 20% effectiveness, if the learning materials fits their learning type.

Dynamics of Railway Wheelsets with a Nonsmooth Contact Force Model

Mate Antali

Publication Name: Springer Proceedings in Mathematics and Statistics

Publication Date: 2024-01-01

Volume: 454

Issue: Unknown

Page Range: 41-53

Description:

The dynamics of a railway wheelset is investigated, focusing on the effect of the contact force models. For large values of creep velocities, the Coulomb model can be used as an asymptotic approximation of wheel-rail contact forces. Then, we get a nonsmooth dynamical system with codimension-2 discontinuities. At the discontinuity of the phase space, the so-called limit directions can be found, which correspond to the possible transitions between slipping and rolling. By this analysis, the nonsmooth model can complement the usual linear creep force model from the opposite direction, and we can explore more details about the qualitative behaviour of the wheelset.

Jung- Kerényi - Pauli and the cognitive individuation Part III: A case study for the cognitive individuation

Peter Varlaki Péter Baranyi

Publication Name: 5th IEEE International Conference on Cognitive Infocommunications Coginfocom 2014 Proceedings

Publication Date: 2014-01-23

Volume: Unknown

Issue: Unknown

Page Range: 647-655

Description:

In the third and final part of the paper we intend to show a 'case study' in the C.G. Jung's cognitive individuation process where Jung himself is the 'undetached observer'. His individuation experience can be a part of the cognitive individuation, in the sense that on the basis of the possible integration of the contents deriving hypothetically from the collective unconscious, along with the acausal synchronistic phenomena associated with the coherent meaning patterns can be identified.
