Dezentrale Ventilatoren in zentralen raumlufttechnischen Anlagen - Berechnungen zur energetischen Vorteilhaftigkeit
(2015)
Mechanische Lüftungsanlagen sind ein zentrales Elementenergieeffizienter, nachhaltiger Gebäude. Die Luftförderung erfolgt bei zentralen Lüftungsanlagen üblicherweise über einen Zuluft- und einen Abluftventilator in der Lüftungszentrale. Jeder Zentralventilator erzeugt eine Druckdifferenz, die sich an dem Widerstand des ungünstigsten Stranges orientiert. Zum Aufteilen des Gesamtvolumenstroms auf die einzelnen Gebäudebereiche wird die Druckdifferenz in den anderen Strängen gezielt abgedrosselt. Die Abdrosselung stellt ...

Uncertainty and Speculators in an Auction for Emissions Permits
(Springer, 2016-04-16)
Auctions have become popular as means of allocating emissions permits in the emissions trading schemes developed around the world. Mostly, only a subset of the regulated polluters participate in these auctions along with speculators, creating a market with relatively few participants and, thus, incentive for strategic bidding. I characterize the bidding behavior of the polluters and the speculators, examining the effect of the latter on the profits of the former and on the auction outcome. It turns out that in addition ...

An Experimental Investigation into ‘Pledge and Review’ in Climate Negotiations
(Springer Netherlands, 2016-06-06)
A novelty of the new Paris Agreement is the inclusion of a process for assessment and review of countries’ nationally determined pledges and contributions. The intent is to reveal whether similar countries are making comparable pledges, whether the totality of such pledges will achieve the global goal, and whether, over the coming years, the contributions actually made by countries will equal or exceed their pledges. The intent is also to provide an opportunity for countries to express their approval, or disapproval, ...

Output 5 ― Evaluation-Tool
(2017)
Purpose – The purpose of this report is to study the success of short-term intensive study programmes (ISPs) over the short-term perspective and highlight additional lessons for students which might be missed without the experience of working face-to-face on sophisticated tasks in multicultural teams.
Approach/ Methodology – The evaluation of our ISPs was conducted using a quantitative methodology, via questionnaires given to students at the beginning, the middle and at the end of a course. The questionnaire development ...

Exploiting non-Markovianity for quantum control
(Nature Publishing Group, 2015)
Quantum technology, exploiting entanglement and the wave nature of matter, relies on the ability to accurately control quantum systems. Quantum control is often compromised by the interaction of the system with its environment since this causes loss of amplitude and phase. However, when the dynamics of the open quantum system is non-Markovian, amplitude and phase flow not only from the system into the environment but also back. Interaction with the environment is then not necessarily detrimental. We show that the ...

Evaluation of breeding strategies for polledness in dairy cattle using a newly developed simulation framework for quantitative and Mendelian traits
(2016-06-29)
Background: Intensified selection of polled individuals has recently gained importance in predominantly horned dairy cattle breeds as an alternative to routine dehorning. The status quo of the current polled breeding pool of genetically-closely related artificial insemination sires with lower breeding values for performance traits raises questions regarding the effects of intensified selection based on this founder pool.
Methods: We developed a stochastic simulation framework that combines the stochastic simulation ...
