How close before you burn? Questions of ethics and distance in researching crisis and unrest
No full textResearchers examining urban riots or unrest constantly face questions about the motivations behind and impact of their work. These questions verge on the existential, because questioning a research topic essentially interrogates researchers’ role and existence as social scientists. With reference to two project examples from Athens, Greece, the author attempts to show how he has so far tried to grapple with such questions. Researching closely and drawing conclusions from distance: this has been a personal model of adjustable distance to the author’s research subjects, a strategy that seem to have somehow worked for the time being, writes Antonis Vradis

Antonis Samaras: The Permanent Campaign Strategy of a Centre-Right Prime Minister
No full textThis chapter focuses on the analysis of Antonis Samaras’ political background and campaigning style of governing in the era of sovereign debt crisis and the implementation of the memoranda. It measures and assesses permanent campaigning of Samaras against the three categories of the proposed theoretical framework (capacity building and strategy, paid and owned media as well as earned media). It finds that as prime minister and in line with his predecessors did follow the permanent campaign trend though he did not use all its features. He put more emphasis on factors related to capacity building and strategy as well as earned media rather than most of the components of the paid and owned media that focused on the use of social media, except for the election themes and negative campaigning. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG
A feature-based approach to re-engineering CAD models from cross sections
No full textWe introduce a novel approach to reconstructing 3D objects from cross sections of point clouds acquired by 3D scanning. In this context cross sections are almost planar clusters of 3D points. We first thin each cluster to obtain an ordered one dimensional set of planar points. We then partition the point set to subsets that can be approximated adequately by piecewise quadratic rational Bezier curves using an optimal fitting method. For each curve we select a number of representative points that lie on the fitting curves which are then used for reconstructing the object surface. Inter-cross section and intra-cross section constraints are imposed to support parameterization and editing of the derived model. Shape and topological differences between adjacent object contours pose several issues for the 3D reconstruction process. By using the contour skeleton information we produce intermediate cross sections representing places where ramifications occur to achieve robust covering (meshing) of adjacent slices. Finally, we present a proof of concept implementation of our method and several examples that demonstrate its effectiveness and efficiency. © 2010 CAD Solutions, LLC.Computer-Aided Design and Application

Paving the way for the integration of synthesis, assessment, and design tools within an ontological framework
No full textThe constant development of new alternatives to treat waste aids in closing material loops towards the circular economy and improving sustainability through the use of new renewable materials and energy. This fact leads to the increasing need for decision-making tools for process synthesis and assessment, which can be addressed with an integrated framework that employs ontologies for knowledge management and optimization tools to perform a hierarchical assessment of alternatives. The systematization of these procedures raises the need for tools to automate techno-economic and life cycle analyses. In this work, such a challenge is addressed through the additional integration of add-on modules such as the CapEx-Opex estimation tools and surrogate modeling within this framework. A case study on plastic waste is proposed with the inclusion of several pyrolysis and gasification alternatives. Results show pyrolysis, followed by the subsequent purification of its products, as the best alternative and helped identify main drivers for technologies feasibility such as feedstock purity and energy consumption.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ChemE/Product and Process Engineerin
Synthesis and optimization of NGL separation as a complex energy-integrated distillation sequence
No full textThe synthesis of heat-integrated distillation sequences for energy-efficient separation of zeotropic multicomponent mixtures is complex due to the many interconnected design degrees of freedom. This paper explores the basis on which reliable screening can be carried out. To solve this problem, a screening algorithm has been developed using optimization of a superstructure for the sequence synthesis using shortcut models, in conjunction with a transportation algorithm for the synthesis of the heat integration arrangement. Different approaches for the inclusion of heat integration are explored and compared. Then the best few designs from this screening are evaluated using rigorous simulations. A case study for the separation of NGL is used to compare options. It has been found that separation problems of the type explored can be screened reliably using shortcut distillation models in conjunction with the synthesis of heat exchanger network designs. Unintegrated designs using thermally coupled complex columns show much better performance than the corresponding designs using simple columns. However, once heat integration is included the difference between designs using complex columns and simple columns narrows significantly.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ChemE/Product and Process Engineerin
Enhanced hot-liquid water pretreatment of biomass with recovery and valorization of side products
No full textLignocellulosic biomass potentially represents a great feedstock for biofuel production, but its’ pretreatment needs to be enhanced in order to make biorefineries competitive with fossil fuel based alternatives. One way to make biorefineries more economically viable is to recover and valorize all generated by-products during the biomass pretreatment step. The main goal of this original research is to design an optimal process for recovering valuable by-products after hot-liquid water pretreatment of poplar biomass. Rigorous models for all operations included in the recovery process are developed using Aspen Plus as a CAPE tool. An optimal downstream processing sequence, consisting of multiple distillation steps, is designed to recover several valuable components, such as acetic acid, formic acid, furfural and 5-hydroxymethylfurfural (HMF).Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.BT/Bioprocess EngineeringChemE/Product and Process Engineerin
