Raw data from: T1-weighted in vivo human whole brain MRI dataset with an ultrahigh isotropic resolution of 250 μm

Falk Lüsebrink, Alessandro Sciarra, Hendrik Mattern, Renat Yakupov & Oliver Speck
We present an ultrahigh resolution in vivo human brain magnetic resonance imaging (MRI) dataset. It consists of T1-weighted whole brain anatomical data acquired at 7 Tesla with a nominal isotropic resolution of 250 μm of a single young healthy Caucasian subject and was recorded using prospective motion correction. The raw data amounts to approximately 1.2 TB and was acquired in eight hours total scan time. The resolution of this dataset is far beyond any previously...

Worksheet Solution Concept

Stefan Werner Knoll
This worksheet is intended for founders in the initial phase, who in addition to a startup idea, have some assumptions about a possible target market and their related customer needs. The result of this worksheet is a description of a solution concept that satisfies possible customer needs of an intended target market. This description forms the basis to think about the business model and the problem-solution-fit. The worksheet belongs to chapter 1.3 Solution Concept of...

Entwicklung des neuronalen Antwortverhaltens im Hippocampus der Ratte und den daraus resultierenden BOLD-fMRT Antworten während wiederholter elektrischer Stimulation des Tractus perforans

Stephanie Riemann
Die fMRT (funktionelle Magnetresonanztomografie) bietet als nicht invasive Methode, die Möglichkeit komplexe Funktionen des Gehirns zu untersuchen. Mit der BOLD (Blut Sauerstoffgehalt abhängige: blood oxygenation level - dependent) fMRT werden lokale Veränderungen der neuronalen Aktivität in einer Region jedoch nur indirekt dargestellt. Um die Zusammenhänge zwischen einem veränderten neuronalen Antwortverhalten und den daraus resultierenden BOLD Antworten zu untersuchen, wurden elektrophysiologische Ableitungen, während gleichzeitiger BOLD fMRT Messungen durchgeführt. Dabei wurde der Tractus perforans, ein Faserbündel, das...

Entwicklung eines Prüfkonzeptes für thermomechanisch hoch beanspruchte Bereiche von Zylinderköpfen und numerische Abbildung der thermischen Belastungszyklen

Vanessa Hammerschmidt
Der Zylinderkopf erfährt im motorischen Betrieb wechselnde Betriebszustände mit überlagerten thermischen und mechanischen Belastungen. Diese induzieren aufgrund von inhomogenen Temperaturverteilungen und der Behinderung der Wärmeausdehnung an Querschnittsübergängen, besonders im Bereich der Ventilstege, thermomechanische Beanspruchungen und können zu einer Bauteilschädigung führen. Um das Bauteilverhalten unter Laborbedingungen zu untersuchen, wird in dieser Arbeit ein Prüfkonzept entwickelt, welches die Beanspruchungssituation im Ventilstegbereich realitätsnah abbildet. Hierfür wird eine Probenform entwickelt, die den geometrischen Randbedingungen eines Ventilsteges entspricht und das...

Similarity-driven prioritization and sampling for product-line testing

Mustafa Zaid Saleh Al-Hajjaji
A software product line comprises a family of software products that share a common set of features. Testing an entire product-line product by product is infeasible, because the number of possible products can be exponential in the number of features. Combinatorial interaction testing is a sampling strategy that selects a presumably minimal, yet suffcient number of products to be tested. Several sampling approaches have been proposed, however, they do not scale well to large product...

Theories of bounded and unbounded rationality in games of conflict and coordination

Michael Mitzkewitz
This dissertation combines four studies which investigate the strategic behavior in games. The first two studies are based on experiments and develop theories of bounded rationality in order to explain the observed behavior. This behavior violates the minimal conditions of game-theoretic rationality, i.e., that equilibrium strategies must be chosen. Instead, real behavior is driven by heuristics like fairness standards and rules of thumb. Game-theoretic rationality is too strong or it is simply inadequate to explain...

Modeling inelastic behaviour of Al-rich Ti-Al alloys at ultra-high homologous temperature

Helal Chowdhury
In this work, the Al-rich TiAl alloy family has been investigated in order to understand the microstructureproperty relationship within the mean-field homogenization approach. This is the first study of Al-rich TiAl alloy family, combining both the material science and mechanics perspective. To understand the origin of different length-scales dependent macroscopic plastic anisotropy and asymmetry is one of the prime objective of this thesis. The appearance of one or more, stable or meta-stable, long-range ordering or...
