Integration einer angepassten FMEA in ein Software-Tool auf Basis von Visual-Basic-for-Applications zur Prognose der menschlichen Fehlerwahrscheinlichkeit in der manuellen Montage
(2020-12)
Das Software-Tool der Montageplanungsmethode MTQM wurde für eine aufwandsärmere Prognose der menschlichen Zuverlässigkeit von manuellen Montagetätigkeiten in der Serienfertigung entwickelt und soll in dieser Arbeit um eine Fehleranalyse in Form einer angepassten FMEA erweitert werden.

How do management practices and farm structure impact productive performances of dairy cattle in the province of Pichincha, Ecuador
(2020-11-11)
The combination of "ancestral knowledge" and modern agricultural techniques are increasingly used by Andes farmers, demonstrating its great importance as an ideal alternative to achieve international standards of productivity and sustainability. Pasture management has demonstrated its relevance in terms of milk volume and quality in farms located in the Ecuadorian highlands, showing a wide range of types of forage resource use, in its constant search for better animal yields from the occupancy rate. However, while ...

Empirical Analyses of the Emergence and the Effect of Inter-municipal Cooperation
(2020-08)
This dissertation presents four empirical studies on inter-municipal cooperation (IMC). IMC gained prominence lately as alternative to local government reform. As local decision makers grow weary of the political costs of amalgamations and discouraging empirical evidence on the effectiveness of such reforms, IMC promises a more flexible approach to the provision of public goods and services.
What are the factors that drive the emergence of IMC? This question is answered by way of survival analysis, using data of ...

An approach to the use of technology in the cocoa-growing sector: a look from the producer
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-03-06)
A study was conducted to keep scientific record of the challenges and opportunities of the insertion of a mobile app for cocoa producers in the Colombia region as a prospective tool or strategy for technological transfer and appropriation into that sector. A survey with structured and semi-structured questions that pertained to cocoa producer men and women was conducted. The questions were related to the general conditions of their labour activities and were discriminant in the following categories: cocoa-grower ...

Literale Praktiken von ambulant betreuten Beschäftigten in Werkstätten für behinderte Menschen
(wbv, 2020)
Die LEO-Studien 2010 und 2018 sind für die in Deutschland lebende Wohnbevölkerung repräsentativ. Einige Bevölkerungsgruppen sind jedoch nur in kleinen Fallzahlen in der Studie abgebildet. Das kann den Eindruck erwecken, sie wurden für unwichtig gehalten werden. In der Praxis der Erwachsenenbildung sind jedoch Überlappungen, zum Beispiel zum Bereich Behinderung, an der Tagesordnung (Hirschberg und Lindmeier 2013). Das gilt auch spezifischer für die Alphabetisierung und Grundbildung (Ditschek 2013; Rosenbladt und Bilger ...

Are there gender differences in access to and demand for East Coast fever vaccine? Empirical evidence from rural smallholder dairy farmers in Kenya
(2020-11-03)
Women lag in the adoption of agricultural innovations compared to men, mainly due to gender inequalities in access to complementary inputs, capital, and knowledge/information. The Infection-and-Treatment-Method (ITM) is considered a safe and effective method of controlling East Coast fever. However, since its commercialisation in Kenya differences in demand for this vaccine among smallholder men and women dairy cattle keepers have not been assessed. Using a sample of 448 respondents, we used an Average-Treatment-Effect ...

A GaN-based DC/DC converter for e-vehicles applications
(IEEE, 2020)
This paper presents a 4 kW GaN-based galvanically isolated bidirectional DC/DC converter suitable for on-board auxiliary power supply systems, interconnecting the HV battery with the LV power system. To enable the trend towards higher levels of electrification, a second LV level of 48 V is introduced to supply the high-power consumers, relieving the 12 V grid on the one hand and/or avoiding using additional costly isolated converters connected to the HV batteries on the other. The built converter prototypes aim to ...

Referring nouns in name-informing quotation: A copula-based approach
(Universität OsnabrückenHumboldt-Universität zu Berlin, 2020)
In name-informing constructions like "The phenomenon is called a “sun halo”", the noun mentioned in the quotation (a “sun halo”) adopts a referring interpretation, as indicated by the determiner. As an account, we claim predicates like call to introduce a copular relation, which is the source of referring uses of nominals in name-informing quotation: To call y “n” entails that y is an n. Two copula types are argued to be covertly contained in name-informing constructions, an identificational copula and an equative ...

Development of CFD-Based Tip Clearance Loss and Deviation Models for Axial-Flow Turbines
(2020-01)
Accurate loss correlations are crucial for reliable turbine performance predictions with low-fidelity tools. However, conventional tip clearance models disregard some important loss effects, e. g. from the relative motion between blades and endwall, and their natural spanwise distributions, which are valuable for through-flow methods. The objective of this thesis is the development of more realistic tip clearance models by means of high-fidelity CFD simulations, which capture all three-dimensional flow effects and ...

Can calcium sprays alleviate jelly seed in mango fruits?
(2020-03-27)
Jelly seed is a major challenge in mango production leading to enormous losses in the value chain. This internal fruit disorder is characterised by disintegration of cells, consistency of jelly and broken cells. Calcium plays an important role in enhancing tissue stability and firmness thus reducing cell disintegration. A two-year field study was conducted in Embu County, Kenya using ‘Van Dyke’ cultivar trees of approximately 10 years old. The objective of the study was to investigate the effect of varied sources of ...
