Most geotechnical design codes and books use the equations of Meyerhof or Terzaghi to calculate shallow foundations. These equations are based on the failure mechanism published by Prandtl for shallow strip foundations. The common idea is that failure of a footing occurs in all cases according to a Prandtl-wedge failure mechanism. To check the failure mechanism and the equations of the currently used bearing capacity factors and correction factors, a large number of finite-element calculations of strip and circular footings have been made. The finite-element calculations show that in cases of soils with high friction angles, soils without cohesion or a surcharge, footings with inclined loading or circular footings, not the Prandtl-wedge failure mechanism, but other failure mechanisms occur. In addition, the currently used equations for the bearing capacity factors and correction factors are too high. Therefore, new equations have been presented in this article. For some correction factors, for example, the inclination factors and the cohesion slope factor, an analytical solution is found. [less ▲]

Recently, some resourceful community-driven initiatives for local food production and retail have arisen in Luxembourg, where low organic agricultural rates are paradoxically paired with high consumer demands. This niche of social innovators is combining agro-ecology with circular economy practices. Four cases of alternative food networks are of interest – studied with qualitative interviews and participant observation. One has been established since the 1980s with 200 employees, partly in social insertion measures. The more recent and smaller initiatives are characterized by a cooperative governance, a community-supported agricultural outlook, hands-on workshops and time-banks, all enabled by social media. These initiatives are more radical in their agro-ecological or permaculture practices, focusing on regenerative land use without relying on imports and fostering the integration of consumers with varying degrees of prosumer involvement, as a politicized step further than mere (possibly industrialized) organic production.

„Die Liebe verwundet, die Liebe fesselt, die Liebe macht krank, die Liebe lässt schwach werden.“ Dieser ursprünglich theologisch geprägte Gedanke über die Gewalt der Liebe, lässt sich – auf seinen bildlichen Kern reduziert – in zahllosen Varianten in der Weltliteratur aufspüren. Eine besonders auffällige Form scheinen dabei jene Texte zu bieten, die Liebe nicht allein als Auslöser, sondern gar selbst als Krankheit darstellen – zumindest implizit, insofern der Zustand des Verliebtseins mit dem Zustand der Krankheit gleichgesetzt wird. Wohl bekannt sind die körperlichen Symptome dieses Liebeszustandes, die in ihrer klassischen Ausprägung im Erbleichen, Erröten, Zittern, in Sprachlähmung sowie im Bluten aus der Nase bestehen und im Mittelalter als minnesiech bezeichnet werden. Erscheint die Liebeskrankheit im Minnesang noch vornehmlich in metaphorischem Gebrauch (s. das gequälte Herz als Beispiel für den Schmerz der Minne), weisen spätere Wörterbucheinträge (vgl. hierzu die Lemmata ‚Liebesfieber’ oder ‚Jungfernkrankheit’) wiederum auf ein stärker körperlich-physiologisches und auch sexuell-erotisches Verständnis von Liebe hin. Krank macht die Minne nun vor allem – und dem mittelalterlichen medizinischen Duktus der Humoralpathologie folgend – dann, wenn das körperliche Begehren nicht befriedigt werden kann. Der hier skizzierte Vortrag will die Vorstellung von Krankheit in einem größeren semantischen Beziehungsgeflecht in den Blick nehmen, das sich in der mhd. Lyrik in bedeutender Weise hervortut: der Verbindung Liebe – Krankheit – Wahn. Der wân als zentrales Symptom der Minnekrankheit löst – so die hier zu erprobende These –den Geist vom versehrten Körper und definiert damit den Übergang von der körperlichen Krankheit(smetapher) zu einer seelischen Zustandsbeschreibung. Die sprachhistorische Herleitung von mhd. wân vermag diese Beobachtung weiter zu untermauern, insofern der Begriff ein zunächst wertneutrales, semantisch vielfältiges Bedeutungsspektrum impliziert, und sich mit ‚Hoffnung, Zuversicht oder Einbildungskraft’ ins Nhd. übertragen ließe. Im krankhaften Minne-wân öffnen sich Denkräume, denen der Minnesang eine literarische Ausgestaltung verleiht; Minne-wân führt damit nicht nur zu körperlicher Versehrtheit, sondern ist eben auch guoter wân, lieber wân, saelden wân – und damit einer der ersten ‚Testräume’ für die Erprobung gedanklicher Spielarten des lyrischen Ichs in der deutschen Dichtung überhaupt.

This presentation focuses on the relationship between the language policy, language ideologies and language practices in a nursery class in trilingual Luxembourg. Individual multilingualism is an educational goal in Luxembourg, a small country in central Europe, and, thus, children learn Luxembourgish from the compulsory nursery school, become literate in German in Year 1 and learn oral and written French from Year 2 and Year 3, respectively. Currently, 62.4% of the children do not speak Luxembourgish on school entry (MENJE 2016). Many speak Portuguese, French or a language of the Balkans. As a result, educational policies focus on the teaching of Luxembourgish from preschool, sometimes at the expense of other languages. Gretsch and Kirsch (2015) developed the app iTEO in order to promote innovative teaching methods that capitalize on the children’s diverse language resources and that promote a dynamic view of bilingualism. This ipad app, which allows for the recording and editing of oral speech, was designed with social-constructivist theories and Bakhtin’s theory of dialogism in mind. This case-study presents the ways in which a preschool teacher’s ideological beliefs influence a child’s language use over a period of two years leading to the child’s understanding of the legitimacy of translanguaging. The focus lies on the interplay between the educational policy focusing on the teaching of Luxembourgish, the teacher’s language ideologies rooted in her multilingual identity and in societal multilingualism, and the child’s experiences of separating languages at home (Kirsch, 2014). The data stem from a qualitative, longitudinal study using a multi-method approach. The study shows that dialogue between teachers, parents, children, policy-makers and researchers can contribute to shifting ideologies and to opening up dynamic languaging spaces. [less ▲]

The paper considers ‘octroyed’, ‘conceded’ or ‘granted’ constitutions of 19th century Europe whose common roots are to be found in the French ‘Charte constitutionnelle’ of 1814. These Charters stem from a paternalistic process of domestic constitution-making engaged unilaterally by a monarch possessing the de facto constituent power and exercising it without the direct involvement of a body representing the people. Such octroyed constitutions, which are of course to be opposed to democratically established ones, show nevertheless a number of specific characteristics which distinguish them also from ‘imposed constitutions’ in the usual sense. The expression ‘constitutional octroy’ should not be used as a synonym for any process leading to an ‘imposed Constitution’. The contribution aims to develop and to validate or invalidate the value of a series of distinctive criteria and possible elements of a definition of ‘octroyed’ or ‘granted’ constitutions in order to underline their specificity.

Hardware-in-the-loop (HiL) testing is an important step in the development of cyber physical systems (CPS). CPS HiL test cases manipulate hardware components, are time-consuming and their behaviors are impacted by the uncertainties in the CPS environment. To mitigate the risks associated with HiL testing, engineers have to ensure that (1) HiL test cases are well-behaved, i.e., they implement valid test scenarios and do not accidentally damage hardware, and (2) HiL test cases can execute within the time budget allotted to HiL testing. This paper proposes an approach to help engineers systematically specify and analyze CPS HiL test cases. Leveraging the UML profile mechanism, we develop an executable domain-specific language, HITECS, for HiL test case specification. HITECS builds on the UML Testing Profile (UTP) and the UML action language (Alf). Using HITECS, we provide analysis methods to check whether HiL test cases are well-behaved, and to estimate the execution times of these test cases before the actual HiL testing stage. We apply HITECS to an industrial case study from the satellite domain. Our results show that: (1) HITECS is feasible to use in practice; (2) HITECS helps engineers define more complete and effective well-behavedness assertions for HiL test cases, compared to when these assertions are defined without systematic guidance; (3) HITECS verifies in practical time that HiL test cases are well-behaved; and (4) HITECS accurately estimates HiL test case execution times.

Applying traditional testing techniques to Cyber-Physical Systems (CPS) is challenging due to the deep intertwining of software and hardware, and the complex, continuous interactions between the system and its environment. To alleviate these challenges we propose to conduct testing at early stages and over executable models of the system and its environment. Model testing of CPSs is however not without difficulties. The complexity and heterogeneity of CPSs renders necessary the combination of different modeling formalisms to build faithful models of their different components. The execution of CPS models thus requires an execution framework supporting the co-simulation of different types of models, including models of the software (e.g., SysML), hardware (e.g., SysML or Simulink), and physical environment (e.g., Simulink). Furthermore, to enable testing in realistic conditions, the co-simulation process must be (1) fast, so that thousands of simulations can be conducted in practical time, (2) controllable, to precisely emulate the expected runtime behavior of the system and, (3) observable, by producing simulation data enabling the detection of failures. To tackle these challenges, we propose a SysML-based modeling methodology for model testing of CPSs, and an efficient SysML-Simulink co-simulation framework. Our approach was validated on a case study from the satellite domain. [less ▲]

Natural language processing techniques, in particular n-gram models, have been applied successfully to facilitate a number of software engineering tasks. However, in our related ICSME ’18 paper, we have shown that the conclusions of a study can drastically change with respect to how the code is tokenized and how the used n-gram model is parameterized. These choices are thus of utmost importance, and one must carefully make them. To show this and allow the community to benefit from our work, we have developed TUNA (TUning Naturalness-based Analysis), a Java software artifact to perform naturalness-based analyses of source code. To the best of our knowledge, TUNA is the first open- source, end-to-end toolchain to carry out source code analyses based on naturalness. [less ▲]

Gravel wash mud (GWM), a waste product from gravel mining was dried and processed into a fine powder to be activated by different concentrations of sodium hydroxide (NaOH) solutions for the synthesis of an alkali-activated binder. The GWM powders were thermally treated at five different calcination temperatures 550, 650, 750, 850 and 950°C. The characterisation of the raw material comprises the particle size distribution (PSD) by laser granulometry, the chemical and mineralogical composition by X-ray fluorescence and X-ray diffraction analysis respectively, and simultaneous thermal analysis. The performance of the alkali-activated binders was examined using compression strength tests and the microstructure was observed using scanning electron microscopy (SEM). The GWM was classified as an aluminosilicate raw material with kaolinite and illite as main clay minerals. Furthermore, a mean particle size around 6.50μm was determined for the uncalcined and calcined GWM powders. The SEM images of the developed binders showed the formation of a compact microstructure, however, relatively low strengths were achieved. This preliminary study highlights an example of an aluminosilicate prime material, which shows very promising chemical and mineralogical characteristics, but its suitability for alkaline activation without further additives was not confirmed as far as performance-based criteria are considered.
