Mechanical properties of MAG butt welded dissimilar structural steel joints with varying strength from grade S355 up to S960 Anzeigen

Mixed connections made of normal-strength and high-strength structural steels allow for optimized material usage and production effort in applications where, as a result of different mechanical effects on materials of the same type, it would otherwise be necessary to adjust the plate th...

Evaluation of methods for measuring tool-chip contact length in wet machining using different approaches (microtextured tool, in-situ visualization and restricted contact tool) Anzeigen

The contact length is one of the most important factors to evaluate the chip formation process and the mechanical loads in metal cutting. Over the years, several methods to identify the contact length were developed. However, especially for wet cutting processes the determination o...

On extra-special Enriques surfaces Anzeigen

We refine Cossec and Dolgachev’s classification of extra-special Enriques surfaces, providing a complete and concise proof.

Feasibility of pressurized intra peritoneal aerosol chemotherapy using an ultrasound aerosol generator (usPIPAC) Anzeigen

Background: We tested the feasibility of ultrasound technology for generating pressurized intraperitoneal aerosol chemotherapy (usPIPAC) and compared its performance vs. comparator (PIPAC). Material and methods: A piezoelectric ultrasound aerosolizer (NextGen, Sinaptec) was compared with the available technolo...

Resources for Turkish natural language processing : a critical survey Anzeigen

This paper presents a comprehensive survey of corpora and lexical resources available for Turkish. We review a broad range of resources, focusing on the ones that are publicly available. In addition to providing information about the available linguistic resources, we present a set ...

Dosage concentration and pulsing frequency affect the degradation efficiency in simulated bacterial polycyclic aromatic hydrocarbon-degrading cultures Anzeigen

A major source of anthropogenic polycyclic aromatic hydrocarbon (PAH) inputs into marine environments are diffuse emissions which result in low PAH concentrations in the ocean water, posing a potential threat for the affected ecosystems. However, the remediation of low-dosage PAH contaminations&#...

Development of a hybrid user interface for skill-based robot programming Anzeigen

Robot programming is a well-known and time-consuming task.\enspace Various methods have been developed over the years to simplify this process. However, most of these methods focus on a singular device for programming. This thesis applies the concept of Hybrid User Interfaces (HUI) ...

Effect of pore space stagnant zones on Interphase mass transfer in porous media, for two-phase flow conditions Anzeigen

Interphase mass transfer is an important solute transport process in two-phase flow in porous media. During two-phase flow, hydrodynamically stagnant and flowing zones are formed, with the stagnant ones being adjacent to the interfaces through which the interphase mass transfer happens. Due&...

Protein engineering for feedback resistance in 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase Anzeigen

The shikimate pathway delivers aromatic amino acids (AAAs) in prokaryotes, fungi, and plants and is highly utilized in the industrial synthesis of bioactive compounds. Carbon flow into this pathway is controlled by the initial enzyme 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase (DAHPS). AAAs&#...

Adaptive triple-fed antenna and thinned RF-chip integration into ultra thin flexible polymer foil Anzeigen

Cutting tool condition monitoring using eigenfaces : tool wear monitoring in milling Anzeigen

Effective monitoring of the tool wear condition within a machining process can be very challenging. Depending on the sensors used, often only a part of the relevant wear information can be detected. In the case of milling processes data acquisition is made even more difficult&...

Biocides in soils of urban stormwater infiltration systems : indications of inputs from point and non-point sources Anzeigen

AbstractUrban stormwater contains various micropollutants, such as biocides, which are washed off from facades during wind-driven rain events. Biocides can reach the groundwater via stormwater infiltration systems (SIS), although the soil layer acts as a reactive barrier preventing the leaching o...

Scalable Rare Earth ion technology for quantum computing nodes Anzeigen

Designing a computational thinking intervention for kindergarten students Anzeigen

In recent years, the emphasis on Future Skills - such as Communication, Critical Thinking, Creativity, Cooperation, and Computational Thinking (CT) - has significantly increased in K-12 education, as these skills can empower students to understand new phenomena that shape society. Various co...

Plants as inspiration for material-based sensing and actuation in soft robots and machines Anzeigen

Because plants are considered immobile, they remain underrepresented as concept generators for soft robots and soft machines. However, plants show a great variety of movements exclusively based on elastic deformation of regions within their moving organs. The absence of gliding parts, as...

Physics-driven machine learning : from biomolecules to crystals Anzeigen

Physical systems and their interactions exhibit inherent equivariance. In machine learning (ML), predicting quantities derived from these interactions follows two main approaches: constructing invariant scalar features as inputs to invariant models or employing equivariant models directly. This thesis focu...
