We propose and implement a modular architecture where Quantum Processing Units (QPUs) operate as peripheral devices, supporting pulse-level control interfaces and high-level circuit execution offloading, while internally managing compilation, transpilation, and scheduling. To enable efficient quantum-classical orchestration, we introduce a Quantum Abstraction Layer (QAL) at the operating system level to enable seamless communication, resource management, and integration with existing software frameworks. Our two-step design approach begins with validating the architecture through simulations in virtualised environments. We then implement an FPGA-based surrogate supporting both result- and timing-accurate modes, enabling full-stack emulation and performance evaluation in the absence of physical quantum hardware. This platform supports extensible and rapid prototyping, Hardware/Software Co-Design, and allows for investigations on the practical quantum advantage under realistic system-level constraints of various use cases.

However, future deployments in both, high-performance computing (HPC) and embedded environments, will demand tighter integration for lower latencies, stronger determinism, and architectural consistency, as well as to implement error correction and other tasks that require tight quantum-classical interaction as generically as possible. We propose a vertically integrated quantum systems architecture that treats quantum accelerators and processing units as peripheral system components. A central element is the Quantum Abstraction Layer (QAL) at operating system kernel level. It aims at real-time, low-latency, and high-throughput interaction between quantum and classical resources, as well as robust low-level quantum operations scheduling and generic resource management. It can serve as blueprint for orchestration of low-level computational components "around" a QPU (and inside a quantum computer), and across different modalities. We present first results towards such an integrated architecture, including a virtual QPU model based on QEMU. The architecture is validated through functional emulation on three base architectures (x86_64, ARM64, and RISC-V), and timing-accurate FPGA-based simulations. This allows for a realistic evaluation of hybrid system performance and quantum advantage scenarios.

This paper introduces a model-driven approach to crosstalk characterisation through three architecture-inspired noise models: (1) simultaneous two-qubit gate execution, (2) shared qubit interference, and (3) proximity-induced noise from shared control or readout hardware. These models act as both diagnostic tools and building blocks for crosstalk-aware quantum programming. We assess their impact across a broad benchmark suite - quantum simulation, Grover's algorithm, and fault-tolerant primitives like surface, Shor, and Steane codes - and evaluate two mitigation techniques: dynamical decoupling and Pauli twirling. While both are discussed in literature, only dynamical decoupling consistently enhances fidelity across noise types. Our work links low-level noise effects to high-level software engineering, underscoring the role of hardware-software co-design in scalable quantum computing. Model-based, hardware-aware design flows and composable noise abstractions improve error mitigation and program portability.

While there are many algorithmic primitives to perform the required calculations, all eventually lead to quantum gates operating on quantum bits, with an order as determined by the structure of the objective function and the properties of target hardware. When the structure of the problem representation is not aligned with structure and boundary conditions of the executing hardware, various overheads degrading the computation may arise, possibly negating any possible quantum advantage. Therefore, automatic transformations of problem representations play an important role in quantum computing when descriptions (semi-)targeted at humans must be cast into forms that can be "executed" on quantum computers. Mathematically equivalent formulations are known to result in substantially different non-functional properties depending on hardware, algorithm and detail properties of the problem. Given the current state of noisy intermediate-scale quantum (NISQ) hardware, these effects are considerably more pronounced than in classical computing. Likewise, efficiency of the transformation itself is relevant because possible quantum advantage may easily be eradicated by the overhead of transforming between representations. In this paper, we consider a specific class of higher-level representations, that is, PUBOs, and devise novel automatic transformation mechanisms into widely used QUBOs that substantially improve efficiency and versatility over the state of the art.

Our results can be used to rate valid paths of transformation in advance—also in automated (quantum) toolchains. We support the automation aspect by considering stability and therefore predictability of free parameters and transformation paths.

Though extensively studied in data management research, the problem remains far from solved: While query optimisers rely on exhaustive search methods to determine ideal solutions for small problems, such methods reach their limits once queries grow in size. Yet, large queries become increasingly common in real-world scenarios, and require suitable methods to generate efficient execution plans. While a variety of heuristics have been proposed for large-scale query optimisation, they suffer from degrading solution quality as queries grow in size, or feature highly sub-optimal worst-case behavior, as we will show. We propose a novel method based on the paradigm of mixed integer linear programming (MILP): By deriving a novel MILP model capable of optimising arbitrary bushy tree structures, we address the limitations of existing MILP methods for join ordering, and can rely on highly optimised MILP solvers to derive efficient tree structures that elude competing methods. To ensure optimisation efficiency, we embed our MILP method into a hybrid framework, which applies MILP solvers precisely where they provide the greatest advantage over competitors, while relying on more efficient methods for less complex optimisation steps. Thereby, our approach gracefully scales to extremely large query sizes joining up to 100 relations, and consistently achieves the most robust plan quality among a large variety of competing join ordering methods.}, language = {en} } @inproceedings{ThelenMauerer, author = {Thelen, Simon and Mauerer, Wolfgang}, title = {Predict and Conquer: Navigating Algorithm Trade-Offs with Quantum Design Automation}, series = {2025 IEEE International Conference on Quantum Computing and Engineering (QCE), 30 August - 05 September 2025, Albuquerque}, booktitle = {2025 IEEE International Conference on Quantum Computing and Engineering (QCE), 30 August - 05 September 2025, Albuquerque}, publisher = {IEEE}, address = {Los Alamitos, USA}, doi = {10.1109/QCE65121.2025.00071}, pages = {591 -- 602}, abstract = {Combining quantum computers with classical compute power has become a standard means for developing algorithms and heuristics that are, eventually, supposed to beat any purely classical alternatives. While in-principle advantages for solution quality or runtime are expected for increasingly many approaches, substantial challenges remain: Non-functional properties like runtime or solution quality of many suggested approaches are not yet fully understood, and need to be explored empirically. This, in turn, makes it unclear which approach is best suited for a given problem. Accurately predicting behaviour and properties of quantum-classical algorithms opens possibilities for software abstraction layers, which in turn can automate decisionmaking for algorithm selection and parametrisation. While such techniques find frequent use in classical high-performance computing, they are still mostly absent from quantum software toolchains. In this paper, we present a methodology (accompanied by a reproducible reference implementation) to perform algorithm selection based on desirable non-functional requirements. This greatly simplifies decision-making processes for end users. Based on meta-information annotations at the source code level, our framework traces key characteristics of quantum-classical heuristics and algorithms, and uses this information to predict the most suitable approach and its parameters for given computational challenges and their non-functional requirements. As combinatorial optimisation is a very extensively studied aspect of quantumclassical systems, we perform a comprehensive case study based on numerical simulations of algorithmic approaches to implement and validate our ideas. We develop statistical models to quantify the influence of various factors on non-functional properties, and establish predictions for optimal algorithmic choices without manual user effort.

They interlace classical computation, in particular optimisation of variational parameters, with quantum-specific routines, and combine problem-specific advantages -- sometimes even provable -- with adaptability to the constraints of noisy, intermediate-scale quantum (NISQ) devices. While circuit depth can be parametrically increased and is known to improve performance in an ideal (noiseless) setting, on realistic hardware greater depth exacerbates noise: The overall quality of results depends critically on both, variational parameters and circuit depth. Although identifying optimal parameters is NP-hard, prior work has suggested that they may exhibit regular, predictable patterns for increasingly deep circuits and depending on the studied class of problems. In this work, we systematically investigate the role of classical parameters in QAOA performance through extensive numerical simulations and suggest a simple, yet effective heuristic scheme to find good parameters for low-depth circuits. Our results demonstrate that: (i) optimal parameters often deviate substantially from expected patterns; (ii) QAOA performance becomes progressively less sensitive to specific parameter choices as depth increases; and (iii) iterative component-wise fixing performs on par with, and at shallow depth may even outperform, several established parameter-selection strategies. We identify conditions under which structured parameter patterns emerge, and when deviations from the patterns warrant further consideration.

Unlike many existing approaches, QEF emphasises iterative, exploratory analysis of evolving experimental strategies rather than exhaustive empirical evaluation of fixed algorithms using predefined quality metrics. The framework's design is informed by a comprehensive review of the literature, identifying principal parameters and measurement practices currently reported in the field. QEF captures all key aspects of quantum software and algorithm experiments through a concise specification that expands into a Cartesian product of variants for controlled large-scale parameter sweeps. This design enables rigorous and systematic evaluation, as well as precise reproducibility. Large sweeps are automatically partitioned into asynchronous jobs across simulators or cloud hardware, and ascertain full hyper-parameter traceability. QEF supports parameter reuse to improve overall experiment runtimes, and collects all metrics and metadata into a form that can be conveniently explored with standard statistical and visualisation software.

This transformation involves a shift from predominantly top-down, unidirectional electricity flows to bidirectional and increasingly complex flow patterns, fundamentally altering the operation and utilization of power systems. The growing integration of distributed energy resources (DERs), heat pumps (HPs), and electric vehicles (EVs) is particularly impacting lower voltage levels, which are evolving from traditionally consumer-dominated networks into active participants in energy dynamics. These developments have a significant influence on reactive power behavior, with many countries already reporting notable changes due to increased Q contributions from lower voltage levels. As bidirectional flows and decentralized generation increase, understanding and forecasting reactive power trends at these voltage levels becomes essential for ensuring grid stability and efficiency. This paper addresses the challenges of long-term Q forecasting in general by analyzing reactive power behavior in grids, the main influencing grid parameters and introducing existing approaches and concepts, analyzing their applicability, and discussing the associated challenges and methodologies.

ECMO is an increasingly used treatment for patients with severe respiratory failure or cardiac arrest [1]. For both, evaluation of therapeutic decisions and fundamental research on patient specific intra-device clotting phenomena, the direct visualization and analysis of clot formation in combination with a detailed flow field correlation is highly desirable and therefore an intensively followed research topic. Modelling blood flow and shear induced coagulation in MLs is challenging. The relevant geometry of oxygenator fibers and chaining threads is complex and spans several length scales. In relevant scales and regimes, blood shows several significant non-Newtonian effects. Viscosity impacts shear rate, which is important in several coagulation mechanisms. Additionally, coagulation processes are influencing fluid properties and geometry significantly. Existing approaches of previous research work are only able to consider some, but not all relevant effects and geometrical details. Due to the enormous size of the discretized geometries, highly detailed viscosity and coagulations models are not applicable. Our goal is to develop a model for combined viscosity and coagulation properties of blood flow in MLs. In our work, we compare the influence of different levels of detail of the ML geometry as well as the influence of considering realistic blood flow behavior (viscosity change by considering the local hematocrit distribution within the F{\aa}hraeus-Lindqvist-Effect) on the resulting flow field in relevant subsections of a ML. High-resolution micro-CT geometry reconstructions [1] are compared to idealized generic fiber representations. For realistic blood flow modelling, Newtonian representation is compared to the established Carreau-Yasuda and a multiphase Euler-Euler approach.

Based on a case study, this paper evaluates the role of district heating networks in reducing electrical distribution grid reinforcements and compares their economic viability against a building-specific heat supply using heat pumps. A detailed energy system model is used to analyze two building energy renovation scenarios: a business-as-usual scenario with a 1 \% annual renovation rate and an ambitious scenario with a rate of 2 \%. Using a two-step optimization, the impact of different district heating network penetration levels on the distribution grid is evaluated, followed by an ex-post analysis to incorporate a simultaneity factor into district heating networks. Overall, district heating networks can reduce distribution grid reinforcements, but the associated savings alone do not justify their construction, particularly in the ambitious renovation scenario. In the business-as-usual scenario, a district heating network can reduce reinforcement costs by up to 71 \%. However, in the ambitious scenario, grid reinforcements are already reduced due to lower heat peak demand, and the maximal reinforcement cost savings only amount to 35 \%. Compared economically, district heating networks are cost-competitive with building-specific heating only in the business-as-usual scenario, up to a heat supply share of 70 \% and in the ambitious scenario, up to 40 \%.

Straight cylinders with a diameter of 380 μm in parallel arrangement were the foundation of the generic model. For validation, a method for reconstructing a native geometry from a microcomputed tomography (μCT) scan was established, with both models used for CFD.

Jahrhunderts in Europa. Eine der Hauptursachen ist der seit 2011 schwelende syrische B{\"u}rgerkrieg, welcher maßgeblich die gesellschaftliche und politische Diskussion in Europa und insbesondere Deutschland pr{\"a}gt. Syrische Migrant:innen bilden die gr{\"o}ßte Gruppe registrierter Asylsuchender und insgesamt die drittgr{\"o}ßte Ausl{\"a}ndergruppe in Deutschland. Damit stellen sie eine relevante und neue Bev{\"o}lkerungsgruppe f{\"u}r die Pr{\"a}vention und Gesundheitsf{\"o}rderung dar. Bisherige Forschung zur Gruppe der syrischen Migrant:innen fokussiert prim{\"a}r auf die psychische Gesundheit. Unklar ist, wie sich einzelne Gesundheitsverhalten dieser Bev{\"o}lkerungsgruppe, z.B. bezogen auf Ern{\"a}hrung und Bewegung, zu Beginn des Aufenthaltes in Deutschland verhalten und wie sich diese Verhaltensweisen mit zunehmendem Aufenthalt ver{\"a}ndern. Die vorliegende Arbeit hat diese Forschungsl{\"u}cke aufgegriffen und folgende Forschungsfragen zu a) dem Stellenwert von Gesundheit und Gesundheitsf{\"o}rderung; b) den Einflussfaktoren auf gesundheitsbezogene Verhaltensweisen; c) dem Zugang zu Pr{\"a}ventionsangeboten; d) unterst{\"u}tzenden sozialen und strukturellen Rahmenbedingungen im Alltag der syrischen Migrant:innen gestellt. Zur Beantwortung der Forschungsfragen wurde ein qualitativ-exploratives Forschungsdesign gew{\"a}hlt, welches dem sozialwissenschaftlichen Ansatz der Grounded Theory nach Glaser und Strauss zugrunde liegt. Die Arbeit umfasst eine longitudinale leitfadengest{\"u}tzte Interviewstudie mit der Zielgruppe zu zwei Zeitpunkten (t₀ n=30, t₁ n=17) sowie eine Fokusgruppenbefragung mit 24 Expert:innen aus dem Bereich der migrationsspezifischen Gesundheitsf{\"o}rderung. Die Narrative der beiden Studien lassen einen zeitlichen Verlauf erkennen, in welchem die eigene Gesundheit sowie gesundheitsf{\"o}rderliche Verhaltensweisen eine unterschiedlich starke Gewichtung im Alltag der Migrant:innen einnehmen. Anhand der Ergebnisse lassen sich drei Phasen formulieren, welche syrische Migrant:innen in ihren ersten Aufenthaltsjahren im Gastland durchlaufen. Die erste Phase ist durch Beh{\"o}rdeng{\"a}nge gepr{\"a}gt, um administrative und rechtliche Sachverhalte zu kl{\"a}ren, wodurch der eigenen Gesundheit sowie gesundheitsf{\"o}rderlichen Verhaltensweisen wenig Relevanz zugeschrieben wird. Der {\"U}bergang von einer ersten hin zu einer zweiten Phase stellt f{\"u}r viele Migrant:innen einen Umbruch dar. Viele erleben in dieser Phase zahlreiche F{\"o}rderfaktoren, um gesundheitsf{\"o}rderliche Verhaltensweisen st{\"a}rker in den Alltag zu integrieren, wie beispielsweise neue Zukunftsperspektiven im Gastland oder westliche Verhaltensnormen. Aufgrund des doppelten biographischen Bruches, welcher mit der Migration nach Deutschland und dem damit verbundenen Auszug aus dem Elternhaus durchlaufen wird, erleben viele Migrant:innen auch Barrieren, um gesundheitsf{\"o}rderliche Verhaltensweisen in gew{\"u}nschtem Umfang umzusetzen. Die soziale Umgebung (z.B. Mitbewohner:innen, Angeh{\"o}rige, Helferkreise) kann dabei eine wichtige St{\"u}tze sein, um gesundheitsbezogene Verhaltensweisen aufrechtzuerhalten. Im {\"U}bergang von Phase 2 zu Phase 3 k{\"o}nnen gesundheitsrelevante Verhaltensweisen etabliert und in die gefestigteren Alltagsabl{\"a}ufe der Migrant:innen eingebunden werden. In Phase 3 ist der Alltag gepr{\"a}gt durch das Absolvieren einer (akademische) Ausbildung oder einer Erwerbst{\"a}tigkeit, welche aufgrund der neuen Sprache als anspruchsvolle Aufgaben gewertet wurde. Die Bew{\"a}ltigung traumatischer Flucht- und Migrationserlebnisse sowie hoher Akkulturationsanforderungen in einem fremden Land erfordern des Weiteren die v{\"o}llige Aufmerksamkeit der Migrant:innen. Diese beiden Faktoren k{\"o}nnen zu einer geringeren Priorisierung gesundheitsf{\"o}rderlicher Verhaltensweisen f{\"u}hren. Der (gemeinsame) Verzehr heimischer Gerichte, kann als kurzeitige Ausflucht aus den psychischen Belastungen fungieren. Auch regelm{\"a}ßige k{\"o}rperliche Aktivit{\"a}t stellt f{\"u}r manche ein geeigneter Coping-Mechanismus dar, um besser mit belastenden Ereignissen umgehen zu k{\"o}nnen. F{\"u}r andere stellt die mentale Situation eine zu große Barriere da, um regelm{\"a}ßig k{\"o}rperlich aktiv zu ein. Anhand der Ergebnisse wurden nach dem Paradigma „health in all policy" der Gesundheitsf{\"o}rderung, elf multisektorial angesiedelte Handlungsempfehlungen f{\"u}r Politik und Praxis formuliert. Sowohl in Politik als auch Public-Health-Praktiken m{\"u}ssen die spezifischen Bed{\"u}rfnisse syrischer Migrant:innen st{\"a}rker eingebunden werden und unterst{\"u}tzende gesellschaftliche Strukturen in der Lern- und Arbeitswelt, als auch der sozio{\"o}konomischen und physischen Umwelt dieser Bev{\"o}lkerungsgruppe geschaffen werden. Zuk{\"u}nftige Forschung sollte sich weiterhin mit den Lebensbedingungen syrischer Migrant:innen und deren Auswirkungen auf gesundheitsrelevante Verhaltensweisen konzentrieren. Aufgrund des anhaltenden Konfliktes in Syrien ist ein fortdauernder Aufenthalt der Zielgruppe in Deutschland anzunehmen, welcher {\"u}ber die in der Arbeit beschriebenen drei Phasen hinausgehen kann.}, language = {de} } @inproceedings{PozzobonWeissMottoketal., author = {Pozzobon, Enrico and Weiß, Nils and Mottok, J{\"u}rgen and Matoušek, V{\´a}clav}, title = {Fuzzy fault injection attacks against secure automotive bootloaders}, series = {21th escar Europe : The World's Leading Automotive Cyber Security Conference (Hamburg, 15. - 16.11.2023)}, booktitle = {21th escar Europe : The World's Leading Automotive Cyber Security Conference (Hamburg, 15. - 16.11.2023)}, publisher = {Ruhr-Universit{\"a}t Bochum}, doi = {10.13154/294-10381}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:294-103817}, pages = {20}, abstract = {Secure embedded bootloaders are the trust anchors for modern vehicles' software. The secure software update process of ECUs is well-defined across the entire automotive industry. Every OEM has his own implementation, but follows the general software update process. This paper demonstrates code execution attacks by combining software and hardware weaknesses in secure automotive bootloaders. The attack can be performed entirely automated, no static code analysisis required. Random fault injection parameters were sufficient to obtain code execution in a reasonable time. All experiments were conducted with electromagnetic fault injection and without any hardware modifications of the targets. We successfully performed our attack on two entirely different gateway Electronic Control Units (ECUs) used in current vehicles (at the time of this research) from Volkswagen and BMW. As a result of this attack, consisting of a combination of a hardware and asoftware attack, the general secure software update process used in the automotive industry needs to be revised.}, language = {en} } @inproceedings{SchroepferSchwaegerlWestfechtel, author = {Schr{\"o}pfer, Johannes and Schw{\"a}gerl, Felix and Westfechtel, Bernhard}, title = {Consistency control for model versions in evolving model-driven software product lines}, series = {2019 ACM/IEEE 22nd International Conference on Model Driven Engineering Languages and Systems Companion (MODELS-C), Munich, Germany}, booktitle = {2019 ACM/IEEE 22nd International Conference on Model Driven Engineering Languages and Systems Companion (MODELS-C), Munich, Germany}, publisher = {IEEE}, doi = {10.1109/MODELS-C.2019.00043}, pages = {268 -- 277}, abstract = {Model-driven software product lines evolve in both time and space.

We propose a novel approach to consistency control called well-formedness analysis and repair: Instead of attempting to guarantee consistency of each configurable version a priori (which is hard and restrictive), consistency is controlled only when a product version is actually configured. Conflicts, i.e., violation of well-formedness constraints, are detected and repaired, driven by configurable strategies.

While combining MDSE and software product line engineering (SPLE) techniques, summarized as model-driven product line engineering (MDPLE), promises increased productivity by relying on organized reuse, the benefits are impeded by transformation specifications designed exclusively for single-variant models. Applying single-variant model transformations to multi-variant input models results in output models lacking the variability information. Multi-variant model transformations (MVMT), which preserve variability information, have only recently been understood as an explicit research problem. In this paper, we propose an a posteriori approach towards MVMT. Following the paradigm of organized reuse, we propose to employ single-variant model transformations without modifications in a first step, and to transfer variability information afterwards based on the artifacts provided by the single-variant transformation specification. In particular, we implemented this approach for the well-known model-to-model transformation language ATL. To deduce variability information, the execution artifacts (trace and execution model) are analyzed. Then, variability annotations are transfered to the target model automatically. The implementation is evaluated based on a practically example of a Graph product line. Results exhibit that our approach outperforms the conventional solution with respect to user effort, accuracy and performance.}, language = {en} } @phdthesis{Schedlbauer, author = {Schedlbauer, J{\"u}rgen}, title = {Anforderungsorientierte Optimierung, Evaluation und Validierung der praktischen Inhalte der Lehre in der Medizinischen Informatik in Hochschulen f{\"u}r Angewandte Wissenschaften (HAW)}, isbn = {978-3-88246-461-0}, doi = {10.5283/epub.47750}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:355-epub-477509}, pages = {xvi, 253}, abstract = {Die European University Association (EUA) definiert „Besch{\"a}ftigungsf{\"a}higkeit" als ein Hauptziel der Hochschulausbildung. Der zentrale Aspekt dieser Arbeit ist, kompetenzorientierte Lehre in der praktischen Ausbildung der medizinischen Informatik an Hochschulen f{\"u}r angewandte Wissenschaft(HAW) durch Analyse der Kompetenzanforderungen des Marktes und der Hochschulen zu optimieren. Als Erstes wird dazu ein Berufsbild der Medizinischen Informatik erarbeitet, indem mit Hilfe von Webcrawling, Webextraktion und Text Mining Begriffe von Stellenanzeigen, anhand einer Inhaltsanalyse, die Kompetenzen im Bereich Fachwissen und Soft Skills (Gesch{\"a}ftsprozessmanagement, Teamwork, Prozesse, Lern- und Probleml{\"o}sungsf{\"a}higkeiten) ermittelt werden. Als N{\"a}chstes wird untersucht, inwiefern HAWs diese Kompetenzen in ihren Modulhandb{\"u}chern als Lernziele definieren. Um die Vermittlung der praktischen Inhalte der Ausbildung entsprechend dem Berufsbild zu optimieren wurde - basierend auf der Methodik des Design-based Research - die Lehrmethodik „INstall" entwickelt und evaluiert um die Arbeitsmarktf{\"a}higkeit der Studierenden zu verbessern. Die Eignung der Lehrmethodik wurde anhand einer Fremd- und Selbsteinsch{\"a}tzung der Studierenden untersucht. Die Ergebnisse der Stellenanalyse zeigen, dass nur 45\% der Begriffe der Kategorie Fachwissen und 55\% der Kategorie Soft Skills zuzuordnen sind. Die vorherrschenden Begriffe waren Programmierung, Erfahrung, Projekt und Server. Die Auswertung der Modulhandb{\"u}cher zur Kompetenzorientierung hat große Unterschiede offengelegt, da in zwei Dritteln der Modulhandb{\"u}cher keine Soft Skills als Lernergebnisse formuliert wurden. Anhand eines Zyklus {\"u}ber drei Vorlesungen wurde nachgewiesen, dass die Erweiterung der Lernziele auf Soft Skills durch die Methode „INstall", in der Fremd- und Selbsteinsch{\"a}tzung der Studierenden einen starken Zugewinn an Kompetenzen im fachlichen Wissen, bei der Teamarbeit, im Gesch{\"a}ftsprozessmanagement, beim Lernen, in der Kommunikation und der Probleml{\"o}sung gebracht hat. Die Arbeit legt den Schluss nahe, dass Hard- und Soft Skills bei den Arbeitnehmeranforderungen zur Medizinischen Informatik gleich gewichtet sind. Daraus kann abgeleitet werden, dass die Vorgaben der Berufsverb{\"a}nde zum Kompetenzprofil {\"u}berdacht werden sollten. Fraglich erscheint, ob ein großer Teil der Modulhandb{\"u}cher den Vorgaben der EUA (Besch{\"a}ftigungsf{\"a}higkeit) entsprechen, da die Lernziele ein Defizit an Soft Skills aufweisen. Insgesamt bleibt festzuhalten: Eine gezielte Ausrichtung der Lernziele von {\"U}bungen auf die Anforderungen des Arbeitsmarktes durch die neue Lehrmethode „INstall" hat zu einer von den Studierenden selbst best{\"a}tigten sp{\"u}rbaren Steigerung der ben{\"o}tigten Kompetenzen gef{\"u}hrt.}, language = {de} } @phdthesis{Schmid, author = {Schmid, Isabel}, title = {Weiterentwicklung von Methoden und Ans{\"a}tzen zur automatisierten Informationsextraktion aus Social Networks}, doi = {10.5283/epub.53491}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:355-epub-534918}, pages = {VII, 192}, abstract = {Ob Werbebotschaften effektiv in einem sozialen Netzwerk verbreitet werden k{\"o}nnen, ist abh{\"a}ngig von der Person, die dabei als Multiplikator eingesetzt wird (Deng et al., 2016).

Neben der großen praktischen Relevanz des Themengebiets hat dieses auch in der Wissenschaft eine Vielzahl an Publikationen hervorgebracht. Eine klare Definition und Abgrenzung einflussreicher Nutzertypen wie z.B. Influencer, Key User oder Lead User fehlt bislang und soll mit Hilfe eines ausf{\"u}hrlichen Literatur{\"u}berblicks angefertigt werden (Ver{\"o}ffentlichung 1). Außerdem wird im Rahmen der Dissertation die Identifikation von Lead User weiterentwickelt, indem verschiedene Analyseformen wie z.B. die SNA, die Sentimentanalyse und das Topic Modeling miteinander kombiniert werden. Das Thema der Sentimentanalyse wird zudem in einer weiteren Ver{\"o}ffentlichung n{\"a}her betrachtet, insbesondere im Zuge der Analyse langer und unstrukturierter Texte.

ESN werden mit dem Ziel angewandt, die organisationale Effektivit{\"a}t sowie die Effizienz im Unternehmen zu verbessern (Stei et al., 2016). Zentral dabei ist, dass die Mitarbeiter dazu motiviert werden, aktiv Inhalte zu erzeugen und ihr Wissen mit anderen zu teilen (G{\"u}nther and Spath, 2010). Hierbei lassen sich auch unter den Mitarbeitern unterschiedliche Nutzergruppen erkennen.
