Dabei bleiben relevante Entwicklungen in ihrer Umwelt häufig unsichtbar. Diese Arbeit geht der Frage nach, wie es gelingt, jenseits des bisher Sichtbaren zu blicken. Aufbauend auf dem radikalen Konstruktivismus und der Luhmannschen Systemtheorie wird untersucht, wie selbstreferenzielle Organisationen durch ihre operative Geschlossenheit bestimmte Umweltphänomene systematisch ausblenden und welche Konsequenzen dieses Ausblenden für ihre Zukunftsfähigkeit hat. Im Zentrum steht das Konzept des Re-Entry. Es beschreibt die Möglichkeit, Ausgeblendetes wieder kommunizierbar zu machen – ohne die Eigenlogik des Systems zu verletzen. Die Arbeit zeigt, wie systemische Beratung dieses Potenzial nutzbar machen kann; nicht als methodische Intervention, sondern als Ermöglichungsform. Sie öffnet Kommunikationsräume, in denen Zukunft als kontingentes Phänomen denkbar und gestaltbar wird. Organisationen werden so in die Lage versetzt, nicht nur ihre Gegenwart zu verwalten, sondern ihre Zukunft aktiv zu gestalten. Ulrich Watermann masterthesis https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13168 Tue, 02 Jun 2026 10:04:44 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13142 Sabrina Ecker; Charlotte Ottenstein; Dominik Vollbracht; Tanja Lischetzke article https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13142 Wed, 27 May 2026 10:12:43 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13162 Im Rahmen der vorliegenden Arbeit konnte durch die Kombination experimenteller und theoretischer Methoden erstmals gezeigt werden, dass der Makrozyklus N,N'-Dimethyl-2,11-diaza[3.3](2,6)pyridinophan (\(L-N_4Me_2\)) in Chrom-Komplexen, wie z.B. \([Cr(L-N_4Me_2)(OAc)_2]\), als monoanionischer Diazapyridinophanligand vorliegt. Damit konnte erstmals die Reduktionsfähigkeit des Makrozyklus sowohl strukturell als auch spektroskopisch eindeutig nachgewiesen werden. Ergänzend zu strukturanalytischen Untersuchungen wurden charakteristische spektroskopische Marker identifiziert, die den Nachweis eines reduzierten tetraazamakrozyklischen Liganden in koordinierter Form ermöglichen. Hierzu zählen insbesondere die geschwächte \(Cr–N_{py}-\)Bindung, eine ausgeprägte intraligand-Elektronenanregung (\(L-N_4Me_2\) → \(L-N_4Me_2\)) sowie die markante antisymmetrische Ringstreckung und -dehnung der Pyridineinheiten am Makrozyklus. Darüber hinaus führte die Einführung fluorierter Acetatoliganden in Form von Trifluoracetatliganden, wie in \([Cr(L-N_4Me_2)(TFA)_2]\), ebenfalls zu einem Chrom(III)-System mit radikalischem (\(L-N_4Me_2 ^•)^⁻\)-Liganden und einem S = 1 Grundzustand. Temperaturabhängige Untersuchungen zeigen eine reversible Änderung des magnetischen Verhaltens, die auf die thermische Population eines angeregten S = 2 Zustands zurückzuführen ist. Für diesen Quintettspinzustand konnte anhand verlängerter \(Cr–N_{amin}-\)Bindungsabstände die Besetzung des high-spin Zustandes nachgewiesen werden, der einer (\(t_{2g})^3(e_g)^1\))-Elektronenkonfiguration entspricht. Die hier beschriebene Verbindung ist somit das erste Beispiel eines Chromkomplexes, der eine temperaturabhängige Valenztautomerie aufweist. Kristin Krämer doctoralthesis https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13162 Wed, 27 May 2026 08:56:53 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13152 Immobilien aller Nutzungsarten prägen das Stadtbild und die Funktionalität von Stadträumen. Mit Blick auf deren Realisierung ist ihr physisch-materielles Konstrukt Ausdruck vorgelagerter Handlungsentscheidungen. Folglich bieten kooperative Handlungen zwischen Kommunen und Projektentwicklern das Potenzial, qualitative Immobilien- und Stadtentwicklungen zu begünstigen. Oft wird dabei unterschätzt, dass Kooperationen kulturelle Grenzüberschreitungen darstellen, die nicht nur die Interessen der jeweiligen Beteiligten berühren, sondern auch deren Identitäten. Die Herstellung eines gemeinsamen Ausschnitts aus den jeweiligen Akteursrealitäten über ein integriertes Problem- und Aufgabenverständnis ist daher eine erforderliche Basis von erfolgsversprechenden Kooperationen. Vor diesem Hintergrund fehlt es jedoch sowohl an Wissen, wie Raumvorstellungen ausgehandelt, vermittelt und legitimiert werden als auch an Wissen, welche Einflussgrößen auf die Interaktion wirken. Die vorliegende Arbeit leistet vor diesem Hintergrund einen Beitrag, diese Forschungslücke zu füllen und das Verständnis über die Ausgestaltung der Interaktion zwischen Kommunen und Projektentwicklern zu erweitern. Kernstück der Arbeit bildet hierzu eine qualitative Inhaltsanalyse, basierend auf 48 leitfadengestützten Experteninterviews mit Vertreter:innen von Stadtplanungsämtern, Ratsmitgliedern, Projektentwicklern, Kapitalgebern sowie Dienstleistungsunternehmen im Planungskontext. Die Untersuchung zeigt, dass institutionell-organisational bedingte Interessenskonflikte zwischen Kommune und Projektentwicklern nicht vollständig auflösbar sind. Darüber hinaus wird der gemeinsame Handlungsrahmen durch externe Einflüsse tendenziell weiter begrenzt. Um sich in diesem „Gerüst“ bewegen und gemeinsame Gestaltungsspielräume schaffen zu können, ist der ernsthafte Wille der handelnden Akteure zur Zusammenarbeit notwendig. Diese vermeintlich offen-sichtliche Voraussetzung für Kooperationen wird in der Planungspraxis jedoch nicht in der Breite gelebt. Inhaltliche Zielkonflikte werden daher durch (latente) Konflikte auf Beziehungsebene verschärft statt entschärft. Die Reflexion von Kooperationsbereitschaft bleibt damit für Wissenschaft und Praxis weiterhin essenziell, wobei aufgrund der Diskrepanz über das Begriffsverständnis von Immobilien – „Lebensumfeld versus Asset“ – und der einhergehenden Verantwortungsübernahme für Immobilien-Projektentwicklungen vielmehr kulturelle Fragestellungen und Wertebewusstsein in den Blick zu nehmen sind als äußere Anreizstrukturen.

Das Modell wurde aus verschiedenen Arbeiten, u.a. zur Wirksamkeit von Lehrkräftefortbildungen (Lipowsky & Rzejak, 2015; Schäfer & van Waveren, 2025) sowie der Trainingsforschung (Alliger et al., 1997; Baldwin & Ford; 1988; Wißhak et al., 2025) abgeleitet. Neben der Strukturierung von Einflussfaktoren werden entlang der Ebenen von Kirkpatrick und Kirkpatrick (2016) auch vier Ebenen zur Evaluation der Wirksamkeit hochschuldidaktischer Lehre dargestellt. Bei diesem Modell handelt es sich um ein Ergebnis aus dem Projekt Transferförderliche Hochschullehre - Ein standortübergreifendes Blended-Learning-Angebot (LehrTransfer).

Ausgangspunkt ist die Beobachtung, dass gesellschaftliche Diversifizierungsprozesse zu einer neuen Qualität sozialer Komplexität und daraus resultierenden Herausforderungen an pädagogisches Handeln führen. Eindeutige Zuschreibungen, stabile Kategorien und lineare Lösungsansätze verlieren dadurch zunehmend an Plausibilität. Auf Grundlage des Konzepts der Superdiversität nach Steven Vertovec werden gesellschaftliche Transformationsprozesse und ihre Bedeutung für die Frühpädagogik analysiert. Daran anschließend werden systemisches Denken und Handeln sowie zentrale systemische Haltungen als professioneller Orientierungsrahmen herausgearbeitet. Die Arbeit zeigt, dass systemische Haltungen einen professionellen Umgang mit sozialer Komplexität ermöglichen, weil sie die Sensibilität für Kontextabhängigkeit, Wechselwirkungen, Mehrdeutigkeit und die eigene Beobachterposition fördern. Anja Wilhelmi-Rapp masterthesis https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13148 Fri, 22 May 2026 12:59:07 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13143 This cumulative dissertation in theoretical macroeconomics presents five articles on deterministic, analytically tractable overlapping-generations models with two-period-lived agents and production. The microeconomic foundations are rooted in contract and game theory, while the analysis of macroeconomic dynamics builds on dynamical systems theory. Article 1 establishes that financial intermediation which provides efficient risk sharing cannot generate endogenous fluctuations. Article 2 examines how competition in the banking sector affects economic growth and welfare in the real sector. Article 3 investigates the impact of market power and strategic interaction in the capital market on savings, capital accumulation, and the qualitative dynamics. Article 4 introduces a novel parameterization of the production-possibility frontier in terms of wage-rental ratios that can enhance both the generality and tractability of two-sector growth models and allows for a refinement of the Rybczynski theorem. Building on this parameterization, Article 5 develops a tractable two-sector model with intergenerational pollution externalities to study the role of fiscal policy in steering the green transformation of an economy. The findings of this dissertation contribute to a deeper understanding of the determinants of economic growth, the sources of real business cycles, and normative welfare implications, while also providing recommendations for policymakers. Paul Maximilian Ritschel doctoralthesis https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13143 Fri, 22 May 2026 11:44:55 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13127 Scientific texts are commonly known to be hard to read. This may be for a number of reasons, such as the fact that they contain a large number of nominalizations, they often use complicated jargon, and sometimes even assume reader knowledge. In order to find ways to make scientific texts clearer, it may be worth to better understand the characteristics of this register. In this thesis, I focus on one aspect of scientific texts: their frequent use of a structure I refer to as complex nominal compounds. Nominal compounds (structures such as "research paper", "linguistic analysis paper") are composed of a head noun ("paper") and one or more modifiers ("research", "linguistic", "analysis"), which can be either nouns or adjectives. Complex nominal compounds are nominal compounds made up of three or more words. Despite decades of research on nominal compounds (complex and otherwise), little is known about how complex nominal compounds are processed, or about how they are used in scientific papers. In this thesis, I take steps towards filling this gap. In my attempt to do so, I recruit two frameworks of language processing and use, through which I produce predictions for the experiments I report here: the Entropy Rate Constancy (ERC) Principle and the Uniform Information Density (UID) Hypothesis. Of particular relevance, not much attention has been given to the UID Hypothesis from the point of view of comprehension. These experiments, therefore, not only contribute towards the understanding of nominal compounds, but also test the validity of these frameworks in general, and of the UID Hypothesis from the perspective of comprehension in particular. On the processing front, the thesis analyzes the L1 and L2 processing of complex nominal compounds, comparing them with a different structure that was predicted to be easier to process: nouns followed by prepositional phrases (e.g., "paper on the analysis of language"). The results do show that compounds are harder to process than the alternative structure, but were not as clear as predicted. On the usage front, the thesis analyzes the distribution of compounds in a corpus of 182 scientific papers of Biology, Linguistics and Economics. Compounds appear with roughly the same frequency throughout the different regions of the papers (i.e., do not cluster in specific areas), and are not reused much after the first use. They are also typically set up by their context, and this does have an impact on the difficulty experienced by readers when encountering them (at least when encountering unfamiliar compounds). The results corroborate the recommendations from writing guides suggesting that compounds should be used with parsimony, but also suggests that familiar compounds do not need to be avoided as much, as that providing contextual support may mitigate some of the difficulties experiencied by readers when encountering these structures. It is my hope that future writing guides will take these findings into consideration. In addition, the results partially support the ERC Principle and the UID Hypothesis, but were not as clear as predicted, and raise questions about the validity of the ERC Principle in texts and of the UID Hypothesis for comprehension.

The fifth generation (5G) mobile communications standard revolutionized the cellular connectivity by adding support for new use cases such as Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC) and massive Machine Type Communications (mMTC). This enabled the foray of cellular communication technologies into new verticals such as Vehicular-to-Everything (V2X) communication, Internet of Things (IoT), industrial communications etc. V2X allows vehicles to directly communicate with each other, roadside infrastructure, and other road users to deliver an array of services. It forms a compelling usecase for 5G due to its potential to provide benefits such as road safety, traffic efficiency, smart mobility, environmental sustainability, and driver convenience. Currently, two Radio Access Technologies (RATs) exist for V2X communication: Intelligent Transportation Systems (ITS)-G5, based on the IEEE 802.11 standard that has been well over 20 years in research and development, and Cellular Vehicle-to-Everything (C-V2X), based on the newer but more established and global 3rd Generation Partnership Project (3GPP) standard. Both technologies have their own pros and cons, with ITS-G5 offering ease of deployment due to its lightweight protocol and complete decentralized operation, whereas C-V2X offers better radio performance, tighter integration with cellular networks etc. Before deploying any RAT, it is important to extensively evaluate it by means of analytical, empirical and Monte-Carlo methods. This forms the core of the first part of this thesis, where a detailed link and system level performance comparison has been carried out for ITS-G5 and C-V2X. A new link-level simulation framework, namely pycv2x, has been developed from scratch for evaluating C-V2X, whereas for ITS-G5 the open-source implementation from ublox was used. An extensive library of digital signal processing blocks for coding, modulation, channel estimation & equalization, and frequency and timing offset correction was developed for C-V2X. The developed simulation framework is tested with the 3GPP reference channel models, and the simulation results match the expected values from the 3GPP Rel.14 specification. Once the link-level simulations are ready for both C-V2X and ITS-G5, the next step is to run Monte-Carlo simulations for a wide variety of channel models. The simulations considered varying channel models, ranging from simple Additive White Gaussian Noise (AWGN) models to multi-path fading models with varying delay profiles. After an extensive literature survey, a total of 8 different channel models (from the International Telecommunication Union (ITU) and Dedicated Short Range Communications (DSRC)) specifically designed for vehicular scenarios were selected and the simulations were carried out. The results show that, in a single transmission scheme, C-V2X outperforms ITS-G5 in almost all of the considered channel models, with some exceptions for 16-Quadrature Amplitude Modulation (QAM) and higher coding schemes. With one blind retransmission enabled, C-V2X exhibits a gain of at least 6 dB and in some cases reaches as high as 10 dB over ITS-G5. Link-level simulations capture the Physical Layer (PHY) performance with a single link only. In order to understand the system capacity, a system level analysis is necessary that considers the upper Media Access Control (MAC) layer schemes. The thresholds for calculating packet errors at the system level are derived from the link level simulation by means of link-system level mapping curves (SNR - BLER curves). In this regard, a realistic system level simulation framework using real-world maps and traffic was developed to evaluate the MAC schemes of ITS-G5 and C-V2X — namely Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) and Semi-Persistent Subchannel Selection (SPSS) respectively. The simulation approach is based on bidirectionally coupling the vehicular traffic simulator (Simulation of Urban Mobility (SUMO)) and the network simulator. The analysis was carried out for European Telecommunications Standards Institute (ETSI) defined scenarios such as highway and Manhattan grid. As an additional novelty, complex scenarios using real-world maps and traffic for the cities of Kaiserslautern and Merzig were also considered for simulation, capturing the traffic characteristics of both urban and rural areas. Overall, it can be seen that C-V2X has a higher range than ITS-G5 in line with the specification. This is reflected in the Packet Error Rate (PER), where ITS-G5 maxes out before C-V2X. In terms of distance, this translates to a range gain of almost 100 m for Quadrature Phase Shift Keying (QPSK) coding schemes and almost 200 m for 16-QAM schemes. C-V2X also makes more efficient use of the spectrum compared to ITS-G5, which can be seen in the form of higher Channel Busy Ratio (CBR). The retransmission gain with C-V2X is significant at higher Modulation & Coding Scheme (MCS) schemes, lower vehicular densities and higher speeds. Machine Learning (ML) / Artificial Intelligence (AI) is a topic that has generated huge interest in both academia and industry, due to the availability of data and the processing power necessary to analyze it. Consequently, it is being widely evaluated and used in almost every engineering domain. The wireless community has also started to embrace ML over the last 5 years, and many works have been carried out to assess its applicability across the entire protocol stack. This forms the core of the second part of this thesis, where different ML strategies were evaluated for signal processing operations such as channel coding, channel estimation, reliability prediction, and obstacle detection. Autoencoders are one of the first applications of ML conceived at the PHY layer, where a well-trained ML model can mimic the behavior of any signal processing block (eventually the entire PHY pipeline). The idea is that if we design a moderately complex ML model and train it with the input and output samples of any given signal processing block (such as coding/modulation), the autoencoder can learn the inherent patterns in the data and, after enough iterations, will start generating the same outputs as the considered signal processing block. In this regard, two ML models were developed for turbo decoding and channel estimation. The first is based on a Recurrent Neural Network (RNN) architecture, which is well suited to understanding time-series patterns and can therefore decode the inherent sequence dependency of turbo codes. The second is based on a Convolutional Neural Network (CNN) architecture, which is good at understanding spatial dependencies and is therefore a better candidate for channel estimation, which involves averaging operations across frequency subcarriers. The models were trained and compared with legacy signal processing blocks, and the results show that the ML-based models perform on par with or sometimes even outperform their legacy counterparts. CNN-based channel estimation in particular is seen to improve the system performance, especially in high-speed scenarios where there is a high Doppler. Proactive link adaptation and management is another key area in wireless communication where ML-based solutions can bring a significant performance gain and add value to the overall RF chain. In this regard, a novel reliability prediction scheme based on Long Short-Term Memory (LSTM) networks is proposed, which predicts the Signal to Interference plus Noise Ratio (SINR) for subsequent transmissions based on previous values obtained after channel equalization. This knowledge can help the transmitter adjust the MCS scheme before a Channel Quality Indicator (CQI) feedback from the receiver arrives. By combining the received CQI with the predicted value, the model can be tuned dynamically to make accurate predictions and subsequently optimize link adaptation. Another novel method for detecting the presence/absence of obstacles with ML algorithms on raw Ultra-Wide Band (UWB) waveforms is also investigated in this thesis. Raw UWB waveforms were collected in indoor/outdoor scenarios and labeled appropriately: 1 denotes the presence of an obstacle (human) and 0 denotes no obstacle. A suite of supervised ML models was trained on the training dataset and used to predict on the test set. The results show that just by using raw waveforms (without any need for further filtering), supervised ML-based methods can detect obstacles with accuracies close to 95%.

Neben administrativen Aufgaben gewinnen insbesondere personale, relationale und reflexive Kompetenzen an Bedeutung. Bestehende Professionalisierungsformate berücksichtigen diese inneren Entwicklungsdimensionen bislang jedoch nur begrenzt. Die vorliegende Masterarbeit untersucht daher, inwiefern die Inner Development Goals (IDGs) als theoretischer Orientierungsrahmen zur Ergänzung bestehender Professionalisierungsformate für Schulleitungen dienen können. Grundlage ist eine theoretisch-konzeptionelle Analyse aktueller Führungsmodelle, Professionalisierungsanforderungen und der fünf IDG-Dimensionen Being, Thinking, Relating, Collaborating und Acting. Die Ergebnisse zeigen, dass die IDGs insbesondere in den Bereichen Selbstführung, Reflexionsfähigkeit, Kooperation und Umgang mit Komplexität eine hohe Anschlussfähigkeit an die Anforderungen modernen Schulleitungshandelns besitzen. Daraus wird ein heuristischer Orientierungsrahmen für die reflexive Professionalisierung von Schulleitungen abgeleitet. Die Arbeit leistet damit einen konzeptionellen Beitrag zur Weiterentwicklung professioneller Qualifizierungsangebote im Schulmanagement. Frederike Weiler masterthesis https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13137 Tue, 19 May 2026 11:53:12 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13125 Interfaces play a crucial role in various physical and chemical phenomena, such as catalysis, molecular recognition, charge transfer, adsorption, and diffusion. While the role of external electric fields in controlling interfacial behavior, such as flow control and droplet manipulation has been well explored, the influence of surface charge on these processes is less understood. Surface charge can arise naturally, as in ferroelectric materials, or be artificially induced through the triboelectric effect in polymers. This research aims to bridge the gap in understanding how surface charge affects key interfacial processes like wetting, spreading, and evaporation. The present study investigates the dynamic interactions at the interface between fluids and charged surfaces, focusing on the interaction between water and lithium niobate (LN), an intrinsically charged ferroelectric material. LN, a ferroelectric material with an exceptionally high surface charge density (theoretically 0.7 C/$\mathrm{m^2}$), was chosen as the primary material for this study. The study begins by investigating classical interface phenomena, including electroosmosis, specifically on a $z$-cut LN surface. Electroosmotic flow in LN-based microchannels is compared with that in glass channels, highlighting the role of spontaneous polarization and surface charge in modulating flow velocity. The study then examines the wetting dynamics of a water droplet on a $z$-cut LN surface, focusing on how polarization direction and surface charge influence its spreading behavior. Additionally, it explores the effects of adsorption and ferroelectric aging on wetting characteristics. The study also investigates the evaporation behavior of water droplets on $z$-cut LN surfaces, examining how factors such as relative humidity and surface polarization direction influence evaporation rates. The evaporation rate on the $z$-cut LN surface is then compared to that of other materials with similar contact angles to assess the unique role of surface charge in evaporation. The final part of the investigation focuses on the fabrication of hydrophobic, photocatalytically active antibacterial surfaces using PDMS and LN. The hydrophobic surface aims to minimize bacterial adhesion, while the photocatalytic activity targets bacterial disinfection. Different fabrication parameters, such as LN concentration, illumination conditions, and surface roughness, are optimized to enhance antibacterial performance. The antibacterial properties of these surfaces were tested using two bacterial strains: \textit{Escherichia coli} DH5$\alpha$ and \textit{Pseudomonas aeruginosa} PA14. This study investigated the often-overlooked impact of surface charge on interfacial processes such as wetting and evaporation. The findings of the study reveal that, despite LN's significantly large surface charge, it does not translate into an exceptionally high zeta potential due to charge neutralization in the Stern layer and a minimal diffuse layer, which limits its potential for electroosmotic flow. The droplet spreading dynamics of LN deviate from classical Tanner's law, with an exponential spreading phase dominating. In addition, the presence of an adsorbed layer substantially reduces the contact angle, accelerating the spreading process. These findings emphasize the importance of cleaning procedures and storage conditions for wetting studies and suggest broader relevance for understanding charge-driven spreading processes, such as electrowetting. The evaporation process on LN involves three stages: constant contact radius, mixed, and stick-slip phases. The stick-slip behavior on the smooth LN surface, even with pure water, indicates strong pinning caused by surface charge and high water affinity. The droplet evaporation studies show that polarization direction significantly affects the initial contact angle, evaporation rate, and total evaporation time, while relative humidity impacts the wettability of the +$z$-cut surface but not the -$z$-cut surface. Antibacterial studies demonstrate that LN-based surfaces can be used as light-stimuli-sensitive, requiring UV illumination for activation, making them effective for reducing bacterial transmission on frequently touched surfaces. Furthermore, the potential for LN's polarization-specific surface chemistry and wettability alterations could be leveraged in fabricating nanoscale devices, sensors, and biocompatible materials for tissue engineering. LN-based materials also hold promise for applications in energy harvesting from droplet motion and stimuli-responsive antibacterial therapeutics, with further research needed to optimize these effects. Sushmitha Vinikumar doctoralthesis https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13125 Mon, 18 May 2026 07:52:25 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13122 Diese Dissertation beschäftigt sich mit der Darstellung, Charakterisierung und Anwendung silikabasierter Hydrierkatalysatoren. Zunächst konnten neuartige Palladium(II)- und Rhodium(I)phosphankomplexe über eine imidazolinium-funktionalisierte Linkergruppe auf SBA 15, Kieselgel sowie einem Janus-Material immobilisiert werden. Die erhaltenen Single-Site-Materialien wurden anschließend mit Wasserstoff reduziert. Nach der Charakterisierung der Katalysatorproben vor und nach der Wasserstoffbehandlung wurde ihre katalytische Aktivität verglichen. Bei der Hydrierung von 2-Cyclohexen-1-on (XIV) zeigte sich dabei eine signifikante Aktivitätssteigerung bei den reduzierten Proben. Weitere neun Olefine konnten in guten Ausbeuten und hoher Selektivität unter Einsatz der reduzierten Katalysatorproben hydriert werden (Reaktionsbedingungen: 100 °C, 15 bar Wasserstoff, 1 mmol Substrat, LM (1 mL), 0.2 mol-% Pd / Rh, 2 h). Aufgrund der vielversprechenden Aktivitäten der mit dem Janus-Material geträgerten Katalysatoren wurde anschließend die Hochskalierung der Synthese dieses Trägers untersucht. Dabei wurde der Einfluss der Anreicherung der Edukte bei konstanten Mengen an Wasser und Ethanol auf die Partikelmorphologie mittels REM-Analysen verfolgt. Ab einem sechsfachen Skalierungsgrad bildeten sich keine Silikahohlpartikel mehr aus. Geringere Ammoniakmengen führten zudem zu löchrigen Partikelwänden. Abschließend wurden neuartige Palladium(II)- und Rhodium(I)phosphankomplexe einer zweiten Generation synthetisiert, welche über eine schwefelhaltige Linkergruppe auf SBA 15 und Kieselgel kondensiert wurden. Analog zu den zuvor beschriebenen Materialien wurden unter einer Wasserstoffatmosphäre die reduzierten Katalysatorproben synthetisiert. Entsprechend war auch bei diesen Materialien eine gesteigerte katalytische Aktivität der reduzierten Proben bei der Hydrierung von 2-Cyclohexen-1-on (XIV) festzustellen. Mittels eingehender struktureller Untersuchung, unter anderem mittels XPS- und TEM-Analysen, konnte dieser Befund maßgeblich auf die Bildung nullvalenter Metallspezies zurückgeführt werden. Unter optimierten Bedingungen konnten schließlich weitere neun Olefine mit guten Ausbeuten unter signifikant milderen Bedingungen hydriert werden (Reaktionsbedingungen: RT, 1 bar Wasserstoff, 1 mmol Substrat, Cyclohexan (2 mL), 0.2 mol-% Pd / Rh, 5 h).

However, its low 0.6V I/O supply voltage and tight timing requirements pose significant challenges to signal integrity and synchronization. This paper presents a full LPDDR4X physical interface (PHY) in GlobalFoundries 12 nm FinFET technology that addresses these issues through novel output driver calibration, digitally controlled delay lines, and de-skewing clock generators. We further incorporate On-Die Termination calibration with comparator offset compensation to ensure robust I/O performance. By integrating a RISC-V subsystem, our PHY enables low-level software control of the memory interface and a fully programmable calibration and training algorithm. The measured results from the fabricated prototype confirm the effectiveness of the proposed strategies, achieving write margins of 300mV/0.61UI at 1.6Gbps and 200mV/0.38UI at 2.133Gbps. Post-layout simulations in all Process-Voltage- Temperature corners at 4.266Gbps show instead write margins of 80mV/0.57UI and 140mV/0.72UI in worst and best corners respectively. The measured output clock amplitude at 2.133GHz is 160mV differential. These findings underscore the feasibility of a LPDDR4X PHY solution that meets stringent performance and power requirements in advanced technology nodes.

The proposed architecture consists of an activeinductive single-stage continuous-time linear equalizer (CTLE) to compensate for the high-frequency channel loss followed by a common-source stage with resistive load to generate a noninverting output as well as enhance the signal swing and sampling margin. Furthermore, an optimized gain-enhancing technique is introduced in the CTLE stage which noticeably improves the low-frequency gain and the output signal swing. In order to evaluate the performance of the proposed gain-enhanced CTLE, two common active-inductive CTLE approaches were designed and simulated in 12nm FinFET technology to compare with the proposed architecture. The simulation results show that the proposed gain-enhancing technique improves the output signal swing of the CTLE by 30% compared to the state-of-the-art with no power and area overhead. The proposed equalizer draws 1.74 mW at a Nyquist frequency of 7.5 GHz and a supply voltage of 0.8 V. In addition, it compensates for a channel attenuation of 22 dB with a figure-of-merit (FoM) of 5.27 fJ/bit/dB, indicating a considerable improvement over previous studies.

This poses significant challenges in sizing due to the inability of using complex modern transistor models, such as the Berkeley Shortchannel IGFET Model (BSIM), to calculate the sizing of the circuits based on hand-analysis. This forces designers to perform iterative simulations, which is time-intensive and error-prone. To address these issues, this work presents an automated sizing approach using pre-computed lookup tables (LUTs) for a 4.3 Gb/s LPDDR4X transceiver in 12nm FinFET technology. The receiver is designed based on gm/ID sizing methodology where look-up tables are used to compute a set of matrices representing the possible design points based on the circuit topology. The design space is constrained by the biasing level, gain, and bandwidth to find an optimised design point in terms of operation region, speed and power. The driver circuit design is automated based on a new algorithm which computes the estimated ON-resistance from the look up table and finds an optimum sizing which fulfills the required impedance range. The calculated sizing of the proposed design approach was used as an input for spectre simulator to compare the simulation results with the input specifications, showing an error margin of less than 1%. Furthermore, the receiver power consumption was evaluated to be 70% less than the work in literature. The proposed driver topology, which uses low voltage swing terminated logic (LVSTL) and near-ground signaling (NGS), provides a 38−120 Ω impedance range at all process, voltage and temperature variations (PVT) for the postlayout results and consumes relatively low power when compared to literature.

Trotz ihrer konstruktiven Vorteile in solchen Einsatzgebieten weisen sie im Vergleich zu Horizontalachsen-Windkraftanlagen eine geringere aerodynamische Effizienz auf. Die gezielte Leistungssteigerung durch strömungsgünstige Rotoranpassungen stellt daher einen zentralen Forschungsschwerpunkt dar. Ihre systematische Umsetzung erfordert jedoch geeignete numerische Entwurfswerkzeuge, mit denen sich die zugrunde liegenden komplexen Strömungsvorgänge effizient analysieren und bewerten lassen. Mit dem Designtool OpenWIEN wird im Rahmen dieser Arbeit eine dreidimensionale Panelmethode entwickelt, die instationäre Strömungsvorgänge an Vertikalachsen-Windkraftanlagen einschließlich einer expliziten Nachlaufstruktur aerodynamisch konsistent abbildet. Um die Aussagekraft der implementierten Methode einzuordnen, erfolgt ein Vergleich mit Ergebnissen zweidimensionaler CFD-Simulationen, anhand derer die Übereinstimmung zwischen beiden Ansätzen im optimalen Betriebsbereich der Anlage bewertet wird. Grundlage des Vergleichs bildet dabei eine dreiblättrige Konfiguration mit NACA-0021-Profil. Darauf aufbauend wird die Panelmethode im Rahmen einer Variantenstudie auf 27 verschiedene Winglet-Konfigurationen angewendet, um ihr Potenzial als effizientes Werkzeug im konzeptuellen aerodynamischen Entwurfsprozess zu evaluieren. Ziel ist es hierbei, leistungssteigernde Konfigurationen zuverlässig zu identifizieren und den Einsatz rechenintensiver, insbesondere dreidimensionaler CFD-Simulationen auf vielversprechende Designvarianten zu beschränken. Hierfür wird neben der aerodynamischen Effizienz auch die strukturelle Belastung in Form des auf die Rotorblätter induzierten Biegemoments in die Bewertung einbezogen. Die Ergebnisse des Vergleichs zwischen OpenWIEN und CFD zeigen im optimalen Betriebsbereich der Windkraftanlage eine weitgehende Übereinstimmung und bestätigen die Konsistenz beider Ansätze. Die anschließende Variantenanalyse belegt zudem, dass sich OpenWIEN für den konzeptuellen Entwurfsprozess eignet und bereits in frühen Entwicklungsphasen belastbare Aussagen zur aerodynamischen Performance verschiedener Winglet-Geometrien zulässt.

Yet, empirical evidence remains limited. Moreover, the mechanisms through which WTRs affect well-being and environmental outcomes are not well understood. Income and time exert distinct influence, while moderating factors such as gender further shape these outcomes. To address these research gaps, my co-authors and I systematically reviewed 30 longitudinal and (quasi-)experimental studies examining the effects of different conceptualisations of WTRs (Manuscript 1). Second, I conducted a quasi-experimental study comparing Swiss employees who reduced their working hours with those who did not (Manuscript 2). Third, I cross-sectionally analysed the same data, focussing on gendered effects on time use and well-being (Manuscript 3). Our findings show that WTRs improve well-being, health, and work-family conflict, but that evidence on environmental effects is less convincing. In the longitudinal study, I found that while lower working hours enhance well-being, lower income negatively affects it, resulting in only short-term improvements in subjective well-being for those reducing their hours. For environmental behaviour, a WTR had small positive impacts for some, but no changes for other environmental behaviours. Furthermore, our research indicates that women may benefit more from WTRs than men regarding work-family conflict, suggesting gender dynamics play a crucial role. This research advances our understanding by synthesising empirical evidence of WTRs across multiple domains with more robust and causally interpretable methods. Importantly, I could replicate that environmental outcomes appear to primarily depend on income effects, whereas framing well-being outcomes in terms of income and time effects alone may be insufficient for understanding the complex dynamics of different factors at play – such as gender, work-family conflict, and time use. Crucially, the counteracting influences of income and working hours on well-being have implications for the income–well-being debate: Working less might provide a more sustainable route to increase well-being than earning more. Finally, my research highlights a possible conflict: Environmental effects of WTRs may require decreasing income, whereas social benefits may require a full wage compensation. Sebastian Felix Neubert doctoralthesis https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13099 Mon, 11 May 2026 18:35:09 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13109 Language is a dynamic and adaptive system, continuously shaped and thus continuously changing based on language users’ interactions, social environments, and cognitive mechanisms. Language contact (i.e., the co-existence and interaction of two or more linguistic systems within individuals or communities) has been recognized historically as a primary source of change. Particularly in bilingual language contact, speakers are systematically exposed to two distinct grammatical systems, constantly shifting between languages and often transferring properties from one language into another. Such transfer can lead among others to the emergence of non-canonical/ungrammatical syntactic structures, hereafter referred to as structural innovations. Structural innovations are particularly crucial to explore in the framework of contact-induced change, as they provide insights into the conditions and constraints of language change processes. However, to better understand how language change occurs and develops in contact situations, we need to investigate the psycholinguistic mechanisms underlying them. On this basis, the present dissertation investigates how bilingual speakers cognitively adapt to structural innovations in their input and how this might lead to potential longer-term language change in a community/society. All studies of this dissertation tested Canadian French-English bilinguals, a population situated in an officially bilingual, yet extremely diverse, environment where language contact has been a persistent historical reality. Each study focuses on a different stage or manifestation of adaptation –whether through changes in speakers’ perception (acceptability judgments), online processing, or production– and together they provide a multidimensional picture of how structural innovations might enter and/or stabilize in bilingual grammars, setting the ground for language change. Foteini Maria Karkaletsou doctoralthesis https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13109 Mon, 11 May 2026 13:57:20 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13103 We study integration and \(L^2\)-approximation of functions in infinite or finite tensor products of Hilbert spaces; our main interest lies in the infinite-variate case. As univariate building blocks of the tensor product, for \(j\in\mathbb{N}\) we consider Hilbert spaces \(H(k_j)\) with reproducing kernels \(k_j\), whose elements are functions on a domain \(D\subseteq\mathbb{R}\). Additionally we assume that the \(H(k_j)\) are spaces of square-integrable functions with respect to a probability measure \(\mu_0\). Commonly studied examples are \(D=[0,1]\) with the uniform distribution \(\mu_0\), as well as \(D=\mathbb{R}\) with the standard normal distribution \(\mu_0\). For \(d\in\mathbb{N}\) or \(d=\infty\), we study integration or \(L^2\)-approximation on the space \(H(\bigotimes_{j=1}^dk_j)\) with respect to the product measure \(\bigotimes_{j=1}^d\mu_0\). To ensure that problems can be solved with reasonable costs and errors in the infinite-variate and the high dimensional case, intuitively speaking, the univariate problems on \(H(k_j)\) have to become easier sufficiently fast as \(j\) increases. We represent this mathematically with the help of suitable smoothness parameters. We study the important special case that the kernels \(k_j\) are given by \[k_j(x,y) = \sum_{\nu\in\mathbb{N}} {\alpha_{\nu,j}^{-1}h_\nu(x)h_\nu(y)},\] where \((h_\nu)_{\nu\in\mathbb{N}}\) is an orthonormal basis in \(L^2(\mu_0)\) and \((\alpha_{\nu,j})_{\nu,j\in\mathbb{N}}\) is a family of positive real Fourier weights. In this case, the growth of the Fourier weights in \(j\) quantifies how fast the univariate problems become easier. As an important example, we study the Hermite polynomials \(h_\nu\) with the standard normal distribution \(\mu_0\) on \(\mathbb{R}\), which leads to Hermite spaces. We determine the polynomial decay of the \(n\)-th minimal errors of the infinite-variate problem in terms of the Fourier weights. The second important special case we study are spaces \(H(k_j)\) whose kernels are given as Gaussian radial basis functions (Gaussian kernels), while our problems are again based on the standard normal distribution \(\mu_0\). We establish the following transference result between spaces with Gaussian kernels and Hermite spaces: The is a one-to-one-correspondence between spaces with Gaussian kernels and Hermite spaces with exponential growth of the Fourier weights such that the integration problem is equivalent on corresponding spaces. An analogue result holds true for the \(L^2\)-approximation problem. Utilizing this equivalence, we are able to constructively transfer upper and lower error bounds from one type of space to the other. In particular we construct almost optimal algorithms for spaces with Gaussian kernels in the infinite-variate case. Additionally, we are able to improve some known results in the finite-variate case.

It also highlights the necessity of combining orthogonal spectroscopic techniques to get a complete understanding of the excited states involved. I performed step-scan FTIR spectroscopy, luminescence spectroscopy and time-correlated single photon counting on multiple series of mono- and oligometallic complexes and thereby identified trends, which can be used in further optimization of the photophysical behaviour of the investigated metalorganic compounds and similar complexes by modifications. The interpretation of the spectra with (TD)-DFT methods helped in distinguishing between similar species as for example with determining the structure of ligands and determining oxidation and spin states of both ground and excited states of not only the original complex, but also intermediate species and photoproducts. The influence of substitution patterns of ligands was investigated and a clear trend between electron donating and electron withdrawing substituents was found by step-scan spectroscopy, while it remained unclear in the photoluminescence measurements alone due to the strong effect of the sample matrix. The replacement of bystander ligands proved to assert severe effects on the lifetimes and TADF capabilities in a series of complexes, strongly suggesting a large involvement of the spin-orbit coupling in the excited states with ligands with elements with higher ordinal numbers. Cooperative effects by metallophilic interactions proved to play a vital role with some metal combinations forming strong intermetallic interactions in the ground and excited states, some in neither state and one other only in the excited state, leading to a structural deformation of the ligand backbone in the excited state geometry. The influence of constitutional isomers was investigated and showed to have stronger effects than originally expected not only increasing lifetimes of excited states, but also transforming dark states into luminescent ones. Finally, the influence of oxidation and spin states on vibrational spectra, especially on the stretching vibrations of hydrogen bonding was utilized to clarify the ground state structures of a series of trimetallic complexes while measurements previous to the investigations seemed to contradict each other. A variety of seemingly minor changes in metalorganic complexes was characterized leading to meaningful insights of how to improve certain properties selectively. Daniel Marhöfer doctoralthesis https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13091 Thu, 30 Apr 2026 14:01:14 +0200 https://kluedo.ub.rptu.de/frontdoor/index/index/docId/13090 The synthesis of logical controllers that guarantee desired specifications is a central problem in the design of cyber-physical systems (CPS). In practice, such guarantees rely on assumptions about how the controller interacts with its environment. These assumptions restrict environment behavior to make synthesis feasible, but in existing approaches they are often overly restrictive, leading to conservative designs and limiting the range of behaviors that systems can safely accommodate. This thesis rethinks the role of assumptions in logical controller synthesis by emphasizing their \emph{permissiveness}---the ability to capture a wide range of admissible environment behaviors. We study permissive assumptions in two key settings: (a) interactions among multiple discrete components in distributed systems, and (b) interactions between high-level logical controllers and low-level physical dynamics in hybrid systems. In both settings, we develop theoretical and algorithmic foundations for computing and exploiting permissive assumptions to enable new design paradigms for logical controller synthesis. For distributed systems, we define permissiveness as capturing all cooperative behaviors of other components that enable a controller to satisfy its specification. We present an algorithm for computing such assumptions in monolithic systems and extend it to distributed systems via a negotiation-based framework that iteratively constructs permissive assume-guarantee contracts for each component. These contracts enable decentralized synthesis and are applied to human-robot interaction, allowing robots to cooperate with humans whenever possible and request cooperation only when necessary. For hybrid systems, we utilize permissive assumptions on the plant model---the abstract representation of physical dynamics---to address three key challenges. To enable seamless adaptation of controllers to changing logical contexts, i.e., changes in high-level goals or tasks, we introduce a novel synthesis framework that utilizes \emph{persistent live groups}, a class of assumptions capturing liveness properties of continuous dynamics. To improve scalability to large or uncertain plant models, we develop \emph{universal controllers} where decisions are conditioned on branching-time assumptions called \emph{prophecies}, which are learned from representative models and efficiently verified at runtime on unseen plant models. Finally, to enhance robustness under uncertainty or partial violations of assumptions on the plant model, we introduce a robust semantics for branching-time temporal logics, enabling formal reasoning about controller behavior under such violations. Overall, this work enables correctness-by-construction synthesis while avoiding unnecessary conservatism, resulting in CPS that are more robust, scalable, and responsive.
