  Power system inertia is an essential part for grid frequency stability and decreases due to the replacement of fossil fuel fired power plants with variable renewable energy sources. This development is not represented sufficiently in unit commitment and economic dispatch models. If considered at all, only synchronous inertia from fossil fuel driven power plants is modelled. This results in increased CO2 emissions, curtailed renewable energy and high system costs. While wind turbines are a source for synthetic inertia and an important renewable energy source, their capability to provide inertia is not incorporated into energy system models. The work at hand closes this research gap and applies a methodology to depict synthetic inertia provided by wind turbines as part of the optimisation dispatch model. A unit commitment and economic inertia dispatch model of the the all-Island Irish power system is created. The potential of wind inertia is analysed and quantified by assessing CO2 emissions, curtailed renewable energy and system costs. Results show that synthetic inertia provided by wind turbines can save up 30.99% of the CO2 emissions, reduce curtailment by up to 39.90% and reduce system costs by 32.72%.

• FlexibleDecay: An automated calculator of scalar decay widths

  Athron, P., Büchner, A., Harries, D., Kotlarski, W., Stöckinger, D., & Voigt, A. (2022). FlexibleDecay: An automated calculator of scalar decay widths. Computer Physics Communications, 283, 27. http://doi.org/https://doi.org/10.1016/j.cpc.2022.108584 (Original work published Februar 2023)

  We present FlexibleDecay, a tool to calculate decays of scalars in a broad class of BSM models. The tool aims for high precision particularly in the case of Higgs boson decays. In the case of scalar and pseudoscalar Higgs boson decays the known higher order SM QED, QCD and EW effects are taken into account where possible. The program works in a modified MS scheme that exhibits a decoupling property with respect to heavy BSM physics, with BSM parameters themselves treated in the MS/DR-scheme allowing for an easy connection to high scale tests for, e.g., perturbativity and vacuum stability, and the many observable calculations readily available in MS/DR programs. Pure BSM effects are taken into account at the leading order, including all one-loop contributions to loop-induced processes. The program is implemented as an extension to FlexibleSUSY, which determines the mass spectrum for arbitrary BSM models, and does not require any extra configuration from the user. We compare our predictions for Higgs decays in the SM, singlet extended SM, type II THDM, CMSSM and MRSSM, as well as for squark decays in the CMSSM against a selection of publicly available tools. The numerical differences between our and other programs are explained. The release of FlexibleDecay officially deprecates the old effective couplings routines in FlexibleSUSY.

  Kann ein regelbasiertes maschinelles Übersetzungssystem eine annehmbare Zieltextqualität generieren? Und wenn ja, wie? Diese Arbeit verbindet die beiden großen Themen Übersetzung und die Redaktion über den Untersuchungsgegenstand der Optimierung maschinell übersetzter Texte. Es werden unter anderem Gemeinsamkeiten in der digitalen Auszeichnung von Sprachdaten für informationsverwaltende Systeme und in der semantischen Kennzeichnung für regelbasierte MÜ Systeme betrachtet. Neben den Untersuchungsergebnissen liefert die Arbeit Vorschläge zur Optimierung der kommunikativen Bedingungen für die regelbasierte MÜ. Neben diesen Inhalten beleuchtet die Autorin Prozesse und Akteure sowie Herausforderungen im Fachgebiet der mehrsprachigen Fachkommunikation.

  We compare different methods for the computation of the real dilogarithm regarding their ability for using instruction-level parallelism when executed on appropriate CPUs. As a result we present an instruction-level-aware method and compare it to existing implementations.

• Are greener start-ups of superior quality? The impact of environmental orientation on innovativeness, high-growth, and internationalization (PREPRINT)

  Abstract

  This paper merges the literature on green and high-quality entrepreneurship by introducing environmental orientation as an unrecognised characteristic of start-up quality and the three quality dimensions innovativeness, high-growth, and internationalisation. Entrepreneurship literature argues that only highquality start-ups contribute to sustainable development and that a better understanding of what determines the quality of start-ups is required. Empirical research has recently shown that the environmental orientation of start-ups is one such determinant, as it significantly predicts their innovativeness. This paper pursues this novel research avenue on the importance of environmental orientation for start-up quality in two ways. First, this paper evaluates and extends this initial evidence on environmental orientation and innovativeness by examining a three times larger sample, covering additional countries and entrepreneurial stages. Second, this paper also analyses the impact of environmental orientation on the quality dimensions of high-growth and internationalisation. Investigation using Global Entrepreneurship Monitor data on 9,650 entrepreneurs from 51 countries revealed that start-ups with a higher environmental orientation are of superior quality regarding their innovativeness, growth expectations, and exports. These results remain robust for start-ups at different entrepreneurial stages, and tests employing different methodological approaches and variable definitions. However, the categorisation into factordriven, efficiency-driven, and innovation-driven countries showed that greener start-ups are more innovative in countries at all three levels of development, while the relationships with high-growth and internationalisation remained significant for only two of the three categories. The findings of this paper provide a new approach for practitioners to identify the small number of high-quality start-ups and an economic reason warranting intensified efforts to support green start-ups.

• Planetarium Talks: Extra dimensions and microscopic black holes

  Vest, A. (2022). Planetarium Talks: Extra dimensions and microscopic black holes.

  Abstract

  anzeigen ▸

  Although Einstein’s general theory of relativity precisely describes the properties of gravity, it is not clear why gravity is so much weaker than the other fundamental forces of nature. The weakness of gravity could be explained, however, by speculative theories that predict spatial dimensions in addition to the three dimensions we experience in our everyday live. One spectacular way of revealing these extra dimensions would be through the formation of microscopic black holes, which, if there are extra dimensions, might be produced at the Large Hadron Collider. Microscopic black holes would be harmless, but their discovery would revolutionize our physical world picture.

• LSP Teacher Training Summer School . The TRAILs project

  Abstract

  This book is the result of research carried out in partnership with seven European universities as part of an Erasmus+ project on training teachers of Language for Specifi c Purpose (LSP) in higher education. All university partners, i.e. Bordeaux (France), Zagreb (Croatia), Jade (Germany), Cádiz (Spain), Adam Mickiewicz (Poland), Ljubljana (Slovenia), Arcola Research (UK), and Bergamo (Italy) carried out surveys and developed a detailed report showing that in Europe there is very little training for this type of teaching, and that teachers generally need to be trained in the specifi cities of the language fi eld they are going to teach. Medical or maritime English, legal Spanish, French for tourism, etc. require both an expert domain knowledge and a grounding in language teaching. Several testimonies highlight this situation and show the lack of career development prospects for LSP teachers at European universities. The members of the Erasmus+ TRAILs project have therefore been interested in the specifi c needs of LSP teachers and have been able to update the information through several types of surveys. The competences of LSP teachers were thus identifi ed. Based on this precise inventory, they are proposing to draw up a complete training programme. A pedagogical approach has been developed: resources, lesson preparation, course design, innovative pedagogical approaches are presented. The research presented in this book goes well beyond the TRAILs project and questions the training of specialised language teachers. More generally, it highlights the need to provide effective training and professional development for LSP teachers and offers a contribution to overcoming the shortcomings of LSP teacher education.
