A theoretical framework for discontinuity capturing: Joining variational multiscale analysis and variation entropy theory
No full textIn this paper we show that the variational multiscale method together with the variation entropy concept form the underlying theoretical framework of discontinuity capturing. The variation entropy [M.F.P. ten Eikelder and I. Akkerman, Comput. Methods Appl. Mech. Engrg. 355 (2019) 261-283] is the recently introduced concept that equips total variation diminishing solutions with an entropy foundation. This is the missing ingredient in order to show that the variational multiscale method can capture sharp layers. The novel framework naturally equips the variational multiscale method with a class of discontinuity capturing operators. This class includes the popular YZβ method and methods based on the residual of the variation-entropy. The discontinuity capturing mechanisms do not contain ad hoc devices and appropriate length scales are derived. Numerical results obtained with quadratic NURBS are virtually oscillation-free and show sharp layers, which confirms the viability of the methodology.Accepted Author ManuscriptShip Hydromechanics and Structure
Perception of nature in the Adam Mickiewicz’s sonnet The Akkerman Steppe and its Russian translations
No full textThe paper analyses Russian translations of The Akkerman Steppes (Crimean Sonnets) from the perspective of perception of nature by the poet and its translations. The author examines their characteristics connected with the interpretation of this poem and the translation choice – a challenging exercise for translators
Sustainable food supply chains – Emerging technologies and strategies toward low-carbon ecosystems
No full textOverall, this special issue of the Journal of Cleaner Production purports to collect emerging decision support models and tools for planning and design sustainable food supply chains, but also to connect to advanced technology able to embrace environmental and social sustainability as leading pillars of integrated food supply chain ecosystems. Considering the size of the sustainability challenge, much work remains to be done to work towards an ecosystem heavily intertwined to climate issues and dependent on natural resources. This ambitious challenge requires increasingly more holistic and multi-disciplinary perspectives on emerging technologies and strategies toward low-carbon ecosystems

Studying agri-food supply chains: an analytical framework
No full textAgri-food supply chains have unique characteristics and challenges for which we need an appropriate analytical framework. In addressing these issues, we first discuss agri-food supply chain characteristics, after which we provide a framework for designing agri-food supply chains. The chapter also provides a quick overview of the structure of the rest of the book

Understanding and improving global agri-food supply chains in an interconnected world: a systems approach
No full textAgri-food supply chains (AFSCs) are complex, interconnected networks that span the world, yet they are highly influenced by regional contexts, as the chapters from this book have illustrated. From large-scale farming in countries like the United States to small and medium-sized farmers in Latin America and Africa, each region presents its own set of challenges and opportunities. These do not only result from regional environmental conditions but also political, economic, social, technological, and regulatory aspects. Using the framework introduced in Chapter 1, this closing chapter synthesizes the content of this book by differentiating between the managed system, the managing system, and the information system to provide an understanding of AFSCs across the world
