The classification of emotions from text is usually done on basis of a single psychological model of emotion and affect with a singletask classifier. The goal of this bachelor thesis is to evaluate the merit of multitask learning across emotion models. Here, a multitask approa...

In recent years, cryptocurrencies implemented on top of Blockchains became very popular, with Bitcoin as the most prominent example. However, novel Blockchain-based platforms such as Ethereum also support distributed applications beyond cryptocurrencies through so-called smart contracts. Technically, smart ...

Die Erzeugung von Zwischenbildern in Bildfolgen ist eines der klassischen Probleme in der Videoverarbeitung. Viele Lösungsansätze dafür arbeiten häufig mit der Information der Bewegung im Bild, um scharfe und realistische Ergebnisse zu erzeugen. Eine Möglichkeit für die verwendete Bewegungsinformation ...

Numerical simulations on mobile devices create new applications supporting engineers and scientists in the field. Boosted by novel augmented reality devices, in-field analysis of complex systems allow engineers to make better decisions and predict the behavior of such systems by assuming&#x...

Die zunehmende Produktvielfalt und die Verkürzung der Produktlebenszyklen erfordern eine schnelle und kostengünstige Rekonfiguration bestehender Produktionssysteme [1]. Um diesen Herausforderungen zu begegnen, ist ein aktuelles digitales Modell der bestehenden Fertigungszelle, im Folgenden Digitaler Zwilling genannt, ein...

Die zunehmende Komplexität hochautomatisierter Systeme bringt neue Herausforderungen bei der Verwaltung ihrer Modelle entlang des gesamten Lebenszyklus des Systems mit sich - von der Kundenakquise über Engineering und Rekonfiguration bis hin zum Systemrecycling. Der Digitale Zwilling ist ein Konzept, ...

The dual-mode interferometer (DMI) is an attractive alternative to Mach-Zehnder interferometers for sensor purposes, achieving sensitivities to refractive index changes close to state-of-the-art. Modern designs on silicon-on-insulator (SOI) platforms offer thermally stable and compact devices with insertion los...

Polyelectrolyte hydrogels play an important role in tissue engineering and can be produced from natural polymers, such as the glycosaminoglycan hyaluronan. In order to control charge density and mechanical properties of hyaluronan-based hydrogels, we developed cross-linkers with a neutral or posi...

Hydrogels are an interesting class of materials used in extrusion-based 3D printing, e.g., for drug delivery or tissue engineering. However, new hydrogel formulations for 3D printing as well as a detailed understanding of crucial formulation properties for 3D printing are needed. In thi...

Hydrogels are versatile materials, finding applications as adsorbers, supports for biosensors and biocatalysts or as scaffolds for tissue engineering. A frequently used building block for chemically cross-linked hydrogels is poly(ethylene glycol) diacrylate (PEG-DA). However, after curing, PEG-DA hydrogels ...

Chemically cross-linkable gelatin methacryloyl (GM) derivatives are getting increasing attention regarding biomedical applications. Thus, thorough investigations are needed to achieve full understanding and control of the physico-chemical behavior of these promising biomaterials. We previously introduced gelatin met...

(Coumarin‐4‐yl)methyl (c4m) and p‐hydroxyphenacyl (pHP)‐based compounds are well known for their highly efficient photoreactions, but often show limited solubility in aqueous media. To circumvent this, we synthesized and characterized the two new c4m and pHP‐based photoacid generators (PAGs), 7‐[bis(carbox...

We dealt with a rather frequent and difficult situation while modelling extreme floods, namely, model output uncertainty in data sparse regions. A historical extreme flood event was chosen to illustrate the challenges involved. Our aim was to understand what the causes might have b...

Holzöfen in Wohnräumen verursachen nicht nur Emissionen von Schadstoffen über den Schornstein in die Außenluft, vielmehr tragen sie auch zur Schadstoffkonzentration in Innenräumen bei. Diese gelangen insbesondere beim Öffnen der Ofentür beim Anfeuern oder beim Nachlegen von Holzscheiten in die In...

„Ordinos“ ist ein vielfältig einsetzbares E-Voting-System. Eine Besonderheit des Systems besteht in der Möglichkeit, die Gesamtzahl erhaltener Stimmen pro Kandidat geheim zu halten („Tally-Hiding“) und trotzdem verifizierbare Informationen über das Ergebnis, z.B. das Ranking der Kandidaten oder nur den...

Ordinos is a novel verifiable tally-hiding e-voting system. At its heart, a homomorphic encryption scheme and secure multi-party computation (MPC) are used to tally votes and securely determine the voting result, without necessarily revealing the full tally (e.g., the number of votes pe...

With multi-party computation becoming more and more efficient and thus more practical, we can start to investigate application scenarios. One application where multi-party computation can be used to great effect is e-voting. Unlike classical e-voting protocols, one can get tally-hiding e-voting&#...

In dieser Arbeit wird das „Multigrid Reduction in Time“ Verfahren vorgestellt und auf die Simulation des neuromuskulären Systems angewendet, um durch zusätzliche Zeitparallelisierung das sehr umfangreiche Differentialgleichungssystem mit entsprechenden Hochleistungsrechnern in kürzerer Zeit zu lösen. Dazu werden...
