The article examines the need for a qualification in the training occupation of chef for vegetarian and vegan food production, which is increasingly being offered due to high demand and economic attractiveness. It compares existing offers and shows the necessity of adapting dual training. Market analyses and statistical data underline the demand for a readjustment of the recently reorganized/modernized training. [ABSTRACT FROM AUTHOR]

Load‐bearing and fatigue behaviour of butt welds in plates of different thicknesses The cross‐section of long‐span steel structures is usually adapted to the bending moment distribution. For this purpose, a thickness transition is applied in the area of butt‐welded joints in flanges of I‐shaped beam members. The fatigue behaviour of these constructional details is complex and differs from a butt‐welded joint in steel plates of the same thickness. This paper presents the results of 30 notch detail tests and compares the behaviour of butt‐welded joints in plates with a thickness transition with those of the same thickness. The statistical analysis of the experimental studies shows a higher fatigue resistance for butt‐welded joints with a thickness transition compared to butt welds of plates of the same thickness. The classification of the latter constructional detail in detail category 90 acc. to FprEN1993‐1‐9:2024 can be confirmed. The prognosis of the notch detail tests with the Two‐Stage‐Model confirms its applicability for the analytical‐numerical prediction of the service life of complex welded constructional details. In addition, the application of the model proves the influence of the thickness ratio and stress ratio on the service life of butt‐welded joints with thickness transition. [ABSTRACT FROM AUTHOR]

Objective: Common spatial pattern (CSP) is a common filter technique used for pre-processing of electroencephalography (EEG) signals for imaginary movement classification tasks. It is crucial to reduce the amount of features especially in cases where few data is available. Therefore, different approaches to reduce the amount of electrodes used for CSP calculation are tried in this research.Methods: Freely available EEG datasets are used for the evaluation. To evaluate the approaches a simple classification pipeline consisting mainly of the CSP calculation and linear discriminant analysis for classification is used. A baseline over all electrodes is calculated and compared against the results of the approaches.Results: The most promising approach is to use the ability of CSP to provide information about the origin of the created filter. An algorithm that extracts the important electrodes from the CSP utilizing these information is proposed.The results show that using subject specific electrode positions has a positive impact on accuracy for the classification task. Further, it is shown that good performing electrode combinations in one session are not necessarily good performing electrodes in another session of the same subject. In addition to the combinations calculated using the developed algorithm, 26 additional electrode combinations are proposed. These can be taken into account when selecting well-performing electrode combinations. In this research we could achieve an accuracy improvement of over 10%.Conclusions: Carefully selecting the correct electrode combination can improve accuracy for classifying an imaginary movement task.

Abstract This article focuses on the visual qualities of Alexander von Humboldt’s statistical tables in his Political Essay on the Kingdom of New Spain (1808–1811, 2nd ed. 1825–1827) with special attention to how such composites of numbers, alphabetical script, and semiotic elements relate to narrative writing. I argue that Humboldt’s tables/tableaus open up spaces inside his narrative that fragment the reading process, inviting new conversations, connections, and ideas. Resumen Este articulo entretiene con los atributos visuales de las abundantes tablas estadísticas incluyendo en el Essai politique sur le royaume de la Nouvelle Espagne (1808–1811, 2nd ed. 1825–1827) de Alexander de Humboldt, en especial con las relaciones entre las combinaciones de números, escritura y elementos semióticos (que Humboldt llama “tableaux”) y la propia narrativa. Obran estas relaciones una fragmentación del proceso de leer, abriendo dimensiones y espacios en que se podrían manifestar nuevas conexiones, conversaciones e ideas innovadoras. Zusammenfassung Dieser Artikel befasst sich mit den bildhaften Eigenschaften der vielen statistischen Tabellen in Alexander von Humboldts Essai politique sur le royaume de la Nouvelle Espagne (1808–1811, 2nd ed. 1820–1827), wobei meine besondere Aufmerksamkeit den Verhältnissen gilt, die diese aus Zahlen, alphabetischer Schrift und semiotischen Elementen zusammengesetzten Komposita (die Humboldt als Tableaux bezeichnet) mit der beschreibenden Erzählung selbst eingehen: In diesen Verhältnissen offenbaren sich nämlich Dimensionen oder Räumlichkeiten, die durch die visuelle Zerteilung des Textes stets weitere, neue Verbindungen, Gespräche und Ideen zu produzieren suchen
