Development of feedback control for energy policy design to guarantee sustainable solar and wind power investment growth
(2021)
Energy transition in the power sector is one of the main pathways to achieving the climate targets. In order to stimulate renewable power development, regulatory policies play a vital role. However, these policies have so far attained only partial results or unexpected consequences due to the unsuitable designs. Therefore, the study addresses the question, “How do regulatory policies have to be designed in order to create a favorable environment for renewable power development?”
This work proposes to use feedback ...

Remote sensing of yield and invasive species in nature conservation grasslands invaded by Lupinus polyphyllus
(2021-07)
Extensiv bewirtschaftetes Grünland und naturnahes Naturschutzgrünland sind wertvolle Bereitsteller von Ökosystemdienstleistungen und könnten eine Schlüsselrolle in zukünftigen Managementstrategien spielen zum Schutz von Arten, die durch den Klimawandel bedroht sind. Jedoch ist extensives Grünland, wie viele andere Ökosysteme, bedroht durch die Ausbreitung invasiver Arten, welche einen großen Einfluss auf den Verlust der Biodiversität haben.
Um den Herausforderungen unserer Zeit zu begegnen, sollten Innovationen in ...

Towards Service Co-evolution in the Internet of Things
(2021-12)
Nowadays, in the world of technology, where the new technologies are devolved and replace the old ones every single day, any software product in order to maintain its competitiveness, must be updated continually. Updating a software product results from an evolution process, including adding new features, replacing outdated features, repairing bugs, closing security gaps, and improving performance, which requires a lot of effort and knowledge. Therefore, the Internet of Things (IoT) services are no exception.

Reasons for consuming rasi as a staple food for the Cireundeu indigenous people: a qualitative study
(2021-09-29)
Rasi (made from cassava) are used as staple food by the Cireundeu indigenous people. This food culture is considered different from the food culture of Indonesian people who generally make rice as their staple food. Therefore, this study aimed to show the reasons Cireundeu indigenous people consume rasi as their staple food. This qualitative research was conducted in Cireundeu Village, Cimahi City, West Java Province, Indonesia. Data was collected from the Cireundeu indigenous people through in-depth interviews and ...

Evaluation of extremely steep residual stress gradients based on a combined approach using laboratory-scale equipment
(2021-11-30)
Surface treatments characterized by rapid heating and cooling (e.g. laser hardening) can induce very steep residual stress gradients in the direct vicinity of the area being treated. These gradients cannot be characterized with sufficient accuracy by means of the classical sin2Ψ approach applying angle-dispersive X-ray diffraction. This can be mainly attributed to limitations of the material removal method. In order to resolve residual stress gradients in these regions without affecting the residual stress equilibrium, ...

Dealing with Opportunism: Experimental Investigations of Measures against Dishonest Behavior
(2021)
This dissertation aims at investigating whether and how distinct measures that are supposed to foster honest behavior work. It consists of three separate papers, in which I analyze the effectiveness and mechanisms of such measures on the basis of several laboratory experiments. Chapter 2 is dedicated to analyzing and comparing the effectiveness of distinct measures that are supposed to prevent people from lying for financial gain. Chapter 3 introduces a novel experimental design that allows the measurement of the ...

Analysis of the nutritional and productive behaviour of dairy cows under three rotation bands of pastures, Pichincha, Ecuador
(2021-12-08)
This research was carried out on Pennisetum clandestinum-based pastures to identify the effect of three (3) types of stocking methods with similar forage allowance (8.2 kg of dry matter for 100 kg of live weight) but differing by the occupation times of the rotations (3 h, 24 h, and continuous) on the behaviour and the production of dairy cows. The experimental scheme consisted in three herds of four Holstein Friesian cows grazing three paddocks, one per rotation type, for one week and replicated three times in a ...

Forage diversity and fertiliser adoption in Napier grass production among smallholder dairy farmers in Kenya
(2021-11-10)
Feed scarcity is one of the major challenges affecting smallholder dairy production in Kenya. Forages are the foundation of livestock nutritional requirements; forage diversification and fertiliser are intensification options that can increase productivity. A sample of 316 and 313 smallholder farmers were surveyed in eastern midlands and central highlands of Kenya, respectively, to establish the types of forages cultivated and the factors that influence fertiliser adoption in Napier grass (Cenchrus purpureus Schumach.) ...
