Systemic Circular Economy Solutions for Fiber Reinforced Composites
This open access book provides an overview of the work undertaken within the FiberEUse project, which developed solutions enhancing the profitability of composite recycling and reuse in value-added products, with a cross-sectorial approach. Glass and carbon fiber reinforced polymers, or composites, are increasingly used as structural materials in many manufacturing sectors like transport, constructions and energy due to their better lightweight and corrosion resistance compared to metals. However, composite recycling is still a challenge since no significant added value in the recycling and reprocessing of composites is demonstrated. FiberEUse developed innovative solutions and business models towards sustainable Circular Economy solutions for post-use composite-made products. Three strategies are presented, namely mechanical recycling of short fibers, thermal recycling of long fibers and modular car parts design for sustainable disassembly and remanufacturing. The validation of the FiberEUse approach within eight industrial demonstrators shows the potentials towards new Circular Economy value-chains for composite materials
Pedestrian Trajectory Prediction in Pedestrian-Vehicle Mixed Environments: A Systematic Review
Planning an autonomous vehicle's (AV) path in a space shared with pedestrians
requires reasoning about pedestrians' future trajectories. A practical
pedestrian trajectory prediction algorithm for the use of AVs needs to consider
the effect of the vehicle's interactions with the pedestrians on pedestrians'
future motion behaviours. In this regard, this paper systematically reviews
different methods proposed in the literature for modelling pedestrian
trajectory prediction in presence of vehicles that can be applied for
unstructured environments. This paper also investigates specific considerations
for pedestrian-vehicle interaction (compared with pedestrian-pedestrian
interaction) and reviews how different variables such as prediction
uncertainties and behavioural differences are accounted for in the previously
proposed prediction models. PRISMA guidelines were followed. Articles that did
not consider vehicle and pedestrian interactions or actual trajectories, and
articles that only focused on road crossing were excluded. A total of 1260
unique peer-reviewed articles from ACM Digital Library, IEEE Xplore, and Scopus
databases were identified in the search. 64 articles were included in the final
review as they met the inclusion and exclusion criteria. An overview of
datasets containing trajectory data of both pedestrians and vehicles used by
the reviewed papers has been provided. Research gaps and directions for future
work, such as having more effective definition of interacting agents in deep
learning methods and the need for gathering more datasets of mixed traffic in
unstructured environments are discussed.Comment: Published in IEEE Transactions on Intelligent Transportation System

Current issues of the management of socio-economic systems in terms of globalization challenges
The authors of the scientific monograph have come to the conclusion that the management of socio-economic systems in the terms of global challenges requires the use of mechanisms to ensure security, optimise the use of resource potential, increase competitiveness, and provide state support to economic entities. Basic research focuses on assessment of economic entities in the terms of global challenges, analysis of the financial system, migration flows, logistics and product exports, territorial development. The research results have been implemented in the different decision-making models in the context of global challenges, strategic planning, financial and food security, education management, information technology and innovation. The results of the study can be used in the developing of directions, programmes and strategies for sustainable development of economic entities and regions, increasing the competitiveness of products and services, decision-making at the level of ministries and agencies that regulate the processes of managing socio-economic systems. The results can also be used by students and young scientists in the educational process and conducting scientific research on the management of socio-economic systems in the terms of global challenges
Advances in Binders for Construction Materials
The global binder production for construction materials is approximately 7.5 billion tons per year, contributing ~6% to the global anthropogenic atmospheric CO2 emissions. Reducing this carbon footprint is a key aim of the construction industry, and current research focuses on developing new innovative ways to attain more sustainable binders and concrete/mortars as a real alternative to the current global demand for Portland cement.With this aim, several potential alternative binders are currently being investigated by scientists worldwide, based on calcium aluminate cement, calcium sulfoaluminate cement, alkali-activated binders, calcined clay limestone cements, nanomaterials, or supersulfated cements. This Special Issue presents contributions that address research and practical advances in i) alternative binder manufacturing processes; ii) chemical, microstructural, and structural characterization of unhydrated binders and of hydrated systems; iii) the properties and modelling of concrete and mortars; iv) applications and durability of concrete and mortars; and v) the conservation and repair of historic concrete/mortar structures using alternative binders.We believe this Special Issue will be of high interest in the binder industry and construction community, based upon the novelty and quality of the results and the real potential application of the findings to the practice and industry
