Description:

The paper examines how real-time data integration enhances communication, coordination, and decision-making in business-to-business (B2B) supply chains. It focuses on the use of Enterprise Resource Planning (ERP), Electronic Data Interchange (EDI), Application Programming Interfaces (APIs), and cloud-based systems to support seamless information exchange between business-to-business partners. Despite advances in digitalization, many organizations struggle to implement a fully integrated communication due to inconsistent data, a lack of standardization, limited interoperability, and restrictions in realtime synchronization across partners. A qualitative pilot study was conducted using semi-structured interviews with seven industry professionals from the manufacturing, automotive, pharmaceutical, healthcare, energy, and logistics sectors, along with case studies of real-world examples from Walmart, Nestlé, and GS1, to understand how these organizations successfully practice integration. The study reveals that firms with consistent master-data governance and integrated platforms achieve higher visibility, improved collaboration, and fewer operational delays. The paper concludes that the stages of digital integration performance include a practical overview of challenges in integration, the technologies currently in use, and key innovations planned for future adoption.

Description:

Multi-purpose dams play a significant role in water resources management and flood protection by storing and releasing water for a sufficient water supply. Significantly, numerous dam failures are observed in multiple regions. Natural hazards related to dams include extreme floods, drought events, earthquakes, and geological conditions. There are also human-induced impacts, such as inadequate dam operation or maintenance. Numerous studies simulate potential natural extreme events to address the wide-ranging consequences encompassing loss of human life, economic losses, and environmental effects. In addition, international commissions and federal agencies recommend and apply a general framework for dam safety and risk assessment. The current study suggests and develops a flexible framework for multi-hazard indices and risk assessment for Darbandikhan Dam, Iraq, which was impacted by successive extreme climate events, besides a strong earthquake (M 7.3) that occurred on November 12, 2017. Consequently, the earthquake led to various impacts along the dam site, including horizontal and vertical displacement in some places. In addition, consecutive years of drought led to significant shortage inflows to the dam reservoir. The current study methodology focuses on developing a multi-hazard index and risk assessment framework for each potential extreme event and failure mode scenario associated with dam operation and safety. The information required for the particular framework is through integrating the observed with a global dataset based on Geographic Information System and Remote Sensing techniques. Nevertheless, using different tools and models in dataset processing provides the acquisition of the essential input data associated with each probable severe event. The outcomes of the suggested framework will show through multi-hazard maps the affected areas (hotspots) and propagation consequences besides the residual risk and system response for each scenario. In conclusion, developing a framework of multi-hazards risks associated with dam operation provides promising outcomes for risk assessment, warning response, and evacuation tasks based on hazard maps with different spatial and temporal resolutions. In addition, the framework can be used as an assistance tool for decision support systems, planning, and environmental protection associated with multi-purpose dam operation and safety.

Green and Sustainable Chemistry in the Work of the United Nations Environment Programme: Results and Options for Future Regulation

Dalma Takó

Publication Name: Chemical Engineering Transactions

Publication Date: 2025-01-01

Volume: 121

Issue: Unknown

Page Range: 103-108

Description:

The expression of green and sustainable chemistry has gained significant attention around the world in recent years. Nowadays, it is evident that green and sustainable chemistry is necessary for Sustainable Development Goals (SDGs); however, the concept and its realisation seem quite vague. Until 2021, green and sustainable chemistry had been defined in different documents, which led to divergent practices. However, in 2021, the United Nations Environment Programme (UNEP) created a Framework Manual on Green and Sustainable Chemistry, which now serves as a uniform guidance for various stakeholders to realise innovation actions and assess management practices for green and sustainable chemistry. Despite its significance, the Framework Manual is not widely known, as it has hardly been analysed, and more seriously, its legal classification has not been examined so far. The aim of this paper is to fill this gap and analyse the Framework Manual from a regulatory viewpoint. In line with this, the study presents the main characteristics of the document, determines the correct legal classification of the document, and makes recommendations regarding the possible improvements of the document and the future regulating options for green and sustainable chemistry. By analysing these questions, the study arrives at significant results: Firstly, it declares that the Framework Manual is a legally non-binding, soft law document. Secondly, it identifies the advantages and disadvantages of soft law regulation. Thirdly, it concludes that the Framework Manual cannot be regarded as a final result. The topic of green and sustainable chemistry should be regulated in a legally binding form in the future. With these results, the study fills the huge gap in legal analysis of the Framework Manual and contributes to the satisfactory future regulation of green and sustainable chemistry.

Skid Resistance of Asphalt Pavements

Szabolcs Rosta László Gáspár

Publication Name: Eng

Publication Date: 2023-06-01

Volume: 4

Issue: 2

Page Range: 1597-1615

Description:

Skid resistance of a road pavement surface is the force developed when a tyre is prevented from rotating and slides along the pavement surface. This property comes from the combination of the macro- and micro-texture of pavement. The skid resistance of an asphalt pavement is an important parameter influencing driving safety on a road since there is a proven relationship between skid resistance and accident parameters. This paper deals with the measurement principle of pavement skid resistance (surface friction) including longitudinal and transverse friction. A high number of measuring devices of skid resistance are also introduced, highlighting their advantages and limitations. Moreover, the measurement policies in the European Union and in Hungary are outlined. Pavement surface texture is investigated, dealing with the levels of surface texture, the most common measuring techniques, the macro-texture features of asphalt types, as well as the Hungarian regulation in the field. As a related topic, the aggregate properties and their implication in the relevant Hungarian specification are introduced briefly as well. Some outcomes of the EU’s COST Action 354 on the development of unified European macro-roughness and skid resistance performance indicators and indices are also presented.

Investigation of the Modified Ballast Breakage Index for a Laboratory Test Series using the Proctor Compactor Machine

Szabolcs Fischer Erika Juhasz

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2025-01-01

Volume: 22

Issue: 4

Page Range: 137-157

Description:

The rock physics properties of the crushed railway ballast include resistance against breakage and wear. The qualification of such materials and their compliance with requirements is mainly considered by two standard tests: The Los Angeles abrasion and Micro-Deval wear resistance tests. These tests are indispensable for the legally mandatory qualification of aggregates, but several measurement methods have been developed that better simulate operating conditions and provide an even more accurate classification of these materials. A Proctor compactor machine was applied to induce a top impact load more similar to the operating conditions of ballast. Pre-screened, sorted, washed, and dried samples of andesite aggregate from four quarries with different rock physics characteristics were used to conduct the test series. The impact load was applied with increasing numbers of blows, i.e., 64, 128, 256 and 1024. Several parameters and indexes were calculated to reveal different relationships, which had to be modified in some cases to obtain estimates as close as possible to those obtained in individual tests. The original Ballast Breakage Index seemed to be an appropriate measure of the change in ballast material quality during deterioration for over a decade. The original calculation method was not consistent with the newly introduced test method. Keeping the principle, however, a modified BBI index calculation method has been developed that fundamentally simplifies the calculation of ballast fragmentation. The whole series of measurements aimed to provide, by material and number of impacts, a series of fragmentation and degradation curves for each of the three repeated measurements, which would give the degradation of samples with different rock physics and grain sizes.

Advancing Lubrication Modeling: A Preliminary Study of Finite Element Solutions for Cavitation-Aware Reynolds Equation †

Balázs Pere Martin Lénárt

Publication Name: Engineering Proceedings

Publication Date: 2025-01-01

Volume: 113

Issue: 1

Page Range: Unknown

Description:

In the modern automotive industry, one of the most challenging tasks is minimizing energy losses caused by friction. Despite its significance, only a limited number of numerical simulation tools are available for effectively addressing lubrication-related problems. The accurate modeling of lubrication phenomena requires solving a specialized form of the Navier–Stokes equations, which accounts for cavitation effects within a thin fluid film. To address this, a finite element software is currently under development to solve the Reynolds equation while incorporating cavitation effect. This advanced tool enables the precise simulation of how the microgeometry of contacting surfaces influences the lubrication characteristics of the fluid film. By optimizing these surface features, the research aims not only to reduce energy dissipation but also to ensure the long-term durability of mechanical components. The findings obtained thus far demonstrate promising improvements in lubrication efficiency and structural longevity. These results, along with the methodological advancements, will be presented in detail at the upcoming conference.

Comparison of Optical Flow-Based Linear Angular Rate Estimation Methods Considering Real Flight Data

Péter Bauer Gabor Jevuczo

Publication Name: IEEE International Conference on Control and Automation Icca

Publication Date: 2025-01-01

Volume: Unknown

Issue: Unknown

Page Range: 829-834

Description:

The angular velocities of an observer moving through an arbitrary scene can be obtained solely from mono camera image sequences, utilizing the optical flow. A major obstacle in this approach is that, the optical flow is non linearly related to the 3-D motion parameters. In this work three possible linear methods are presented to solve this nonlinear equation and then these methods are evaluated and compared using real mono camera images and real sensor measurements collected during two test flights.
