Removing Barriers for Integrating Dimensional Conceptualisations of Personality Disorders into Clinical Practice
(2023)
The present dissertation investigated the utility of dimensional personality disorder (PD) models for clinical practice, specifically focusing on the Alternative Model of Personality Disorders (AMPD) as implemented in the DSM-5 and the dimensional PD conceptualization in the ICD-11. The dissertation research consisted of three studies that addressed various aspects of clinical utility of dimensional PD models, including practical utility regarding assessment of the severity of personality pathology, the quantification ...

Female farmers in the Galapagos: An invisible force
(2023-11-07)
Despite the crucial contributions of women to agriculture and food security, female farmers in the Galapagos Islands face persistent challenges that hinder the recognition and valuation of their work. Furthermore, the lack of gender-disaggregated data tailored to their local and contextual realities presents an ongoing challenge for evidence-based policy formulation, hampering the response to their specific needs and challenges. Taking a departure from the dominant quantitative approach in agricultural research, this ...

Unionsrechtliche Maßnahmen zugunsten des beschleunigten Ausbaus von erneuerbaren Energien
(2023)
Bislang beschränken sich die Vorgaben der Richtlinie über erneuerbare Energien darauf, bestimmte Anteile erneuerbarer Energien am Energiemix vorzuschreiben. So sah Art. 3 im Jahr 2018 vor, den Anteil am Gesamtenergieverbrauch bis 2030 auf 32 % zu steigern. Art. 16 verlangt bislang vor allem die Einrichtung von Anlaufstellen, Regelungstransparenz und eine Verfahrensdauer von zwei, ausnahmsweise drei Jahren. Inhaltliche Vorgaben für Genehmigungsverfahren fehlen dagegen bislang noch.
In jüngster Zeit unternimmt die ...

Zweiskalensimulation von mikroheterogenen Strukturen aus spröden Faserverbundwerkstoffen
(Kassel Univ. Press, 2010)
Die vorliegende Dissertation behandelt die Zweiskalensimulation von mikroheterogenen Faserverbundwerkstoffstrukturen. Die Berechnung von Bauteilen aus inhomogenen Werkstoffen wird als Mehrskalenaufgabe betrachtet. Im Gegensatz zum Stand der Technik, der im Allgemeinen von der Betrachtungsweise des Werkstoff als homogenes Kontinuum ausgeht, berücksichtigt der in dieser Arbeit verfolgte, methodische Ansatz den inhomogenen Materialaufbau aus verschiedenen Werkstoffphasen. Die Auslegung von Faserverbundbauteilen hinsichtlich ...

Influence of Surface Mechanical Attrition Treatment (SMAT) on Microstructure, Tensile and Low-Cycle Fatigue Behavior of Additively Manufactured Stainless Steel 316L
(2023-08-29)
Direct Energy Deposition (DED), as one common type of additive manufacturing, is capable of fabricating metallic components close to net-shape with complex geometry. Surface mechanical attrition treatment (SMAT) is an advanced surface treatment technology which is able to yield a nanostructured surface layer characterized by compressive residual stresses and work hardening, thereby improving the fatigue performances of metallic specimens. In the present study, stainless steel 316L specimens were fabricated by DED and ...

Propagation and branching strategies for job shop scheduling minimizing the weighted energy consumption
(2023)
We consider a job shop scheduling problem with time windows, flexible energy prices, and machines whose energy consumption depends on their operational state (offline, ramp-up, setup, processing, standby or ramp-down). The goal is to find a valid schedule that minimizes the overall energy cost. To solve this problem to optimality, we developed a branch-and-bound algorithm based on a time-indexed integer linear programming (ILP) formulation, which uses binary variables that describe blocks spanning multiple inactive ...

Identifying critical demand periods in capacity planning for networks including storage
(2023)
We consider a capacity planning problem for networks including storage. Given a graph and a time series of demands and supplies, we seek for integer link and storage capacities that permit a single commodity flow with valid storage in- and outtakes over all time steps. This problem arises, for example, in power systems planning, where storage can be used to buffer peaks of varying supplies and demands. For typical time series spanning a full year at hourly resolution, this leads to huge optimization models. To reduce ...

Pathogenic Mutations in Catalytic Subunit Isoforms of the cAMP-Dependent Protein Kinase
(2023)
Protein kinase A (PKA) is an integral part in a myriad of cellular pathways and a main effector of the second messenger cAMP. Since its discovery in the late 1960s, PKA has become one of the best-studied eukaryotic protein kinases in terms of enzymatic and structural features. Pathological implications of PKA have just started to emerge. There are three main isoforms (α, β, γ) of the catalytic subunit of PKA (PKA-C) which constitute a holoenzyme (R2C2) by association with a regulatory subunit (PKA-R) dimer. While ...

Orometry, Intrinsic Dimensionality and Learning: Novel Insights into Network Data
(2023-11)
Today, networks are an integral part of our world. Let it be real-life friendship networks or social connections that are based on social media. In this thesis, we contribute to the understanding of networks by studying networks from three different perspectives. First, we adapt notions and concepts from orometry to metric data and networks to gain novel insights from a local perspective. Specifically, we study measures of local outstandingness and propose concepts to derive small hierarchies from larger networks. ...
